organism confirms the diagnosis in 2 to 8 days; (4) there is a membrane which is

firmly adherent and which extends beyond the tonsil. The disease is reportable

to public health authorities.

Differential diagnosis. This includes nonspecific tonsillitis, infectious

mononucleosis, Vincent's angina, candidiasis, agranulocytosis, leukemia, and

syphilis.

Treatment. Antiserum in a dose of 200 to 500 IU/kg must be given intramuscularly

at the earliest reasonable suspicion of the diagnosis, i.e., before

bacteriologic confirmation. In severe cases a high dose of 1,000 IU/kg may be

given accompanied by antibiotic cover. Treatment also includes bed rest, oral

hygiene. Diphtheria immunization by diphtheria toxoid is protective but does not

become effective for several weeks.

Complications. These include general toxicity, failure of the heart and

circulation, hemorrhagic nephritis or nephrosis, palatal paralysis due to

polyneuritis, airway obstruction, and danger of asphyxia. A proportion of the

population are silent carriers of the disease.

Normally, excretion of virulent diphtheria bacteria ceases after several weeks.

However, carriers may remain a source of infection for months or even years.

Cultures are therefore necessary until three cultures at weekly intervals are

negative.

Long-term carriers should be treated by local and parenteral antibiotics and

local disinfection. If this does not eradicate the organism, it may be necessary

to carry out tonsillectomy, accompanied by adenoidectomy in children, to remove

the source.

 

Tonsillitis

 

CLASSIFICATION OF TONSILLITIS

 

I. Acute.

1) Primary: catarrhal, lacunar, follicular, Vincent’s tonsillitis

(ulceromembranous tonsillitis).

2) Secondary:

a) in acute infectious diseases: diphthteria, scarlet fever, tularemia,

abdominal typhoid;

b) in blood vascular diseases: infections mononucleosis, agranulocytosis,

alimentary-toxical aleukia, leukemia.

II. Chronic.

1) Nonspecific:

a) stage of compensation;

b) stage of decompensation.

2) Specific: having infectious granulomatous-tuberculosis, syphilis, scleroma.

 

Acute Tonsillitis

 

Symptoms. The disease usually begins with high temperature and possibly chills,

especially in children. The patient complains of a burning sensation in the

throat, persistent pain in the oropharynx, pain on swallowing, and pain

irradiating to the ear on swallowing. Opening the mouth is often difficult and

painful, the tongue is coated, and there is oral fetor. The patient also

complains of headaches, thick speech, marked feeling of malaise, and swelling

and tenderness of the regional lymph nodes. Both tonsils and the surrounding

area including the posterior pharyngeal wall are deep-red and swollen, but in

catarrhal tonsillitis there is no exudate on the tonsil. Later, yellow spots

corresponding to the lymphatic follicles form on the tonsils, hence the name

follicular tonsillitis. Alternatively, yellow spots occur over the openings of

the crypts, hence the name lacunar tonsillitis. A membrane occurs in

ulceramembranous tonsillitis, but is seldom confluent and rarely spreads beyond

the tonsil. There is also swelling of the neighboring organs such as the faucial

pillars, the uvula, and the base of the tongue. The patient also complains of

sialorrhea and difficulty in eating.

Pathogenesis. The most common organism is the beta-hemolytic streptococcus.

Staphylococci, pneumococci, mixed flora, hemophilus influenza, and E. coli are

much less common. If the symptoms worsen and multifocal symptoms occur, a

generalized disorder expressing itself particularly in the lymphoepithelial

organs should be suspected. On the other hand, there are also tonsillar

infections in which the generalized symptoms are minimal and only the local

changes can be recognized. Virus infections are particularly important in this

respect, e.g., herpangina. The tonsillar parenchyma is infiltrated with

leukocytes in tonsillitis, causing small abscesses in the parenchyma and in the

crypts. In addition, a fibrinous exudate is formed and there are marked changes

in the parenchyma and the epithelium.

Bacteria are constantly present in the mouth and pharynx. These saprophytic



organisms include: saprophytic streptococcus viridans, pneumococci, fusiform

bacteria, leptothrix, neisseria. lactobacteria, staphylococci, sarcina, and

fungi.

These saprophytic organisms may become pathogenic due to a change in

environment.

A virus infection may prepare the way for secondary bacterial infection.

Diagnosis. This is made from the clinical picture of an acute onset with high

fever, pains in the neck and on swallowing, redness and exudate on the tonsils,

and from general investigations of the blood picture, the erythrocyte

sedimentation rate (ESR), the heart and circulation, and the urine. Appropriate

tests or even cultures are carried out if diphtheria is suspected, and blood

tests are done for mononucleosis.

Differential diagnosis. This includes scarlet fever, diphtheria, infectious

mononucleosis, agranulocytosis, leukemia, hyperkeratosis of the tonsils, stage 2

syphilis, and in unilateral disease, peritonsillar cellulitis or abscess,

tuberculosis, and tonsillar tumors.

Treatment. This consists of bed rest, analgesics, bland fluid diet, high-dose

penicillin for 10 days, and observation for complications. Local care should

include oral toilet and dental hygiene. Disinfectant and analgesic mouthwashes

may be used.

Course. Tonsillitis usually resolves within I week. On the other hand,

complications may occur such as respiratory obstruction due to laryngeal edema,

otitis media, or rhinosinusitis; sequelae may occur.

The following laboratory investigations should be done in tonsillitis:

1. Smear and culture to exclude diphtheria and determine causative bacteria

2. Urinalysis to exclude nephritis

3. Differential blood count to exclude mononucleosis and leukemia.

Vincent’s Angina (Angina Ulceromembranacea)

 

The patient usually complains of unilateral pain on swallowing, and there is

ipsilateral swelling of the jugulodigastric nodes. There is an ulcer, which is

often deep, on one tonsil with a whitish exudate, whose site of predilection is

the upper pole. The local findings are often impressive in contrast to the

symptoms, which are often slight. There may only be a feeling of a foreign body

in the throat, and the patient also has a characteristic oral fetor. Usually

there is no fever. The exudate which can be easily wiped off does not extend to

the palate, buccal mucosa, and gingiva.

Microbiology. There is an obligatory symbiosis of a spirochete and fusiform

rods.

Diagnosis. This is made on the clinical picture of a typical infection usually

of one tonsil, with unilateral lymphadenopathy, and on the results of bacterial

culture.

Differential diagnosis. This includes diphtheria, tuberculosis, syphilis,

tonsilar neoplasms, acute leukemia, agranulocytosis, and infectious

mononucleosis.

Treatment. Penicillin is given for 3 to 6 days. The course is usually short and

the prognosis good.

 

Chronic Tonsillitis

 

Chronic tonsillitis requires particular attention on diagnostic grounds because

it is difficult to differentiate from a normal tonsil. It may also be a focus of

infection with effects on the entire body.

Symptoms. The history usually shows recurrent attacks of tonsillitis, but this

is not always the case. There is often little or no pain in the neck or

difficulty on swallowing. There is a halitosis and a bad taste in the mouth. The

jugulodigastric lymph nodes are often enlarged. Chronic tonsillitis often

remains more or less symptomless. The systemic effect may declare itself by

lowering of resistance, tiredness, tendency to catch colds, unexplained high

temperature, and loss of appetite.

Pathogenesis. The organisms are usually a mixed flora of aerobic and anaerobic

bacteria in which streptococci predominate. Group A beta-hemolytic streptococci

are especially likely to cause focal symptoms. Poor drainage of the branching

crypts leads to retention of cell debris which forms a good culture medium for

bacteria. From such crypt abscesses, the infection extends via the epithelial

defects of the reticular epithelium into the tonsillar parenchyma to form a

cryptic parenchymatous tonsillitis. Alternatively it penetrates into the

capillaries surrounding the crypts, allowing intermittent or continuous

penetration of toxins and organisms into the general circulation. In the long

term, the tonsillar parenchyma undergoes fibrosis and atrophy.

Diagnosis.

a) History shows recurrent acute or subacute attacks of tonsillitis.

b) Local Findings

- The tonsils are more or less fixed to their bed as shown by the depressor

test.

- The tonsillar surface is fissured or scarred.

- Watery pus and greyish-yellow material may be pressed out of the opening of

the crypts by a tongue depressor.

- Reddening of the anterior faucial pillar is present

- Peritonsillar tenderness is present

- Lymphadenopathy of the jugulodigastric group is found

c) General Findings

- History shows recurrent tonsillitis, unexplained high temperature, lowering of

resistance, etc.

- Blood picture: there is increased ESR.

The presence of fixed yellow tonsillar debris on pressure on the crypts by a

tongue depressor is not evidence of a chronic tonsillitis but is a physiologic

phenomenon (tonsillar plugs). The size of the tonsil is also not a criterion for

the presence of chronic tonsillitis. This disease can occur in large

hyperplastic tonsils, but is more common in small and medium-sized tonsils. It

is not always possible to make the diagnosis of chronic tonsillitis from the

local findings. The history and general findings must also be assessed

critically. The judgment and experience of the examiner is often decisive.

There are two stages of chronic nonspecific tonsillitis: stage of compensation

and stage of decompensation.

Stage of decompensation:

- Recurrent acute tonsillitis (more then 3 times per year)

- Peritonsillar abscess

- Tonsillogenic septicemia

- Tonsillogenic or posttonsillitis focal symptoms (diseases of the heart,

joints, kidneys, etc.).

Treatment.

Tonsillectomy is absolutely indicated in the following cases:

1. Chronic tonsillitis, stage of decompensation:

2. Marked hypertrophy of the tonsil causing mechanical obstruction.

3. If a tonsillar tumor is suspected.

Contraindications include pharyngitis sicca, leukemia, agranulocytosis, serious

generalized disorders such as tuberculosis or diabetes, and ulcerative or

destructive processes extending beyond the tonsil if the diagnosis has not been

confirmed.

The age of the patient has no contraindication in doubtful cases.

The previously popular tonsillotomy has now become obsolete because of the

danger of postoperative development of foci in the remaining scarred tonsillar

remnant. This is also true for procedures such as incising the tonsil.

The decision to advise tonsillectomy should not be taken lightly. Much critical

experience is required.

The balance between immunobiologic considerations and the local pathologic

findings must be weighed carefully before advising tonsillectomy, particularly

in children.

Conservative treatment: tonsillar irrigation, aspiration of the tonsils,

electrocoagulation.

Principles of Tonsillectomy

 

Tonsillectomy is usually carried out under local anesthesia. An incision is made

in the anterior faucial pillar, and the connective tissue layer between the

tonsillar parenchyma and the pharyngeal constrictor muscles is demonstrated. The

tonsil is then freed by combined blunt and sharp dissection proceeding from the

upper pole to the base of the tongue, preserving the faucial pillars. The entire

tonsillar tissue must be removed. Hemostasis is secured by pressure, ligatures,

or electrocautery. The same procedure is then carried out on the opposite side.

Complications include hemorrhage which may occur up to the 14th postoperative

day.

In countries where there is risk of infection by poliomyelitis, tonsillectomy

should not be carried out during the warmer season of the year. Tonsillectomy

should also not be carried out during epidemics of other infectious diseases.

Tonsillectomy by cryosurgery is technically easier and may be used for patients

with coagulation disorders or in poor general condition. Otherwise, it is not to

be recommended since compete removal of the entire tonsil cannot be guaranteed

and the procedure may need to be repeated for remnants of tonsillar tissue.

 

Complications During and After Tonsillitis

 

Posttonsillitis complications include rheumatic fever, often with a symptomfree

interval of 4 to 6 weeks, and endo-, myo-, or pericarditis. Acute

glomerulonephritis and focal nephritis, which require urinalysis after

resolution of the tonsillitis, are diseases secondary to streptococcal

infection.

 

Local Complications

Peritonsillar Abscess

 

Symptoms. Rapidly increasing difficulty in swallowing occurs after a symptomfree

interval of a few days after tonsillitis. The pain usually irradiates to the

ear, and opening of the mouth is difficult due to trismus. The speech is thick

and indistinct. The pain is so severe that the patient often refuses to eat, the

head is held over to the diseased side, and rapid head movements are avoided.

The patient has sialorrhea and oral fetor, swelling of the regional lymph nodes,

increase of fever with high temperatures of 39° to 40°C, and the general

condition deteriorates rapidly. He also has an intolerable feeling of pressure

in the neck, obstruction of the laryngeal inlet, and increasing respiratory

obstruction. However, the symptoms may on occasion be only mild. Simultaneous

bilateral abscesses may occur.

Pathogenesis. Inflammation spreads from the tonsillar parenchyma to the

surrounding tissue, peritonsillitis, and forms an abscess within a few days. The

pharyngeal constrictor muscle is usually an effective barrier against further

spread.

Diagnosis. This is made on the clinical picture of swelling, redness, and

protrusion of the tonsil, the faucial arch, the palate, and the uvula. The uvula

is pushed to the healthy side, and there is marked tenderness of the tonsillar

area. Inspection of the pharynx may be difficult because of severe trismus.

There is an exudate on the tongue, rarely on the tonsils and palate. The blood

picture and ESR are typical of an acute infection. When the swelling is

fluctuant, it may be possible to aspirate its contents for diagnosis.

Differential diagnosis. This includes peritonsillar phlegmon, tonsillogenic

sepsis, allergic swelling of the pharynx without fever (angioneurotic edema),

malignant diphtheria, agranulocytosis, specific tonsillar infections

(tuberculosis and syphilis), and nonulcerating tumors of the tonsil or

neighboring tissues (malignant lymphoma, lymphoepithelial tumor, anaplastic

carcinoma, or leukemia).

Conservative treatment. High doses of antibiotics, e.g., penicillin or

cephalosporin, etc., for I week at least, can only prevent the formation of an

abscess in the early stages of infiltration of the peritonsillar tissues.

Analgesics, a fluid diet, cold foods, an ice pack to the neck, and mouthwashes

are prescribed.

Operative Treatment.

1. Abscess tonsillectomy which is usually carried out under local anesthesia.

This procedure may be performed on all patients who are fit for operation,

particularly those with a recurrent peritonsillar abscess. It prevents further

recurrence, the patient must endure only one course of treatment and time is

saved.

2. Drainage of the abscess followed by tonsillectomy 3 to 4 days later under

local anesthesia.

Principles of drainage of the abscess. Local anesthesia is induced carefully

with 3% topical Dicaine, and infiltration anesthesia with 1% Novocaine plus

Adrenaline 0,1% is used at the site of the intended incision. Pus often drains

from the puncture site when the anesthetic agents is introduced. The anesthetic

must be allowed approximately 5 min to act before incision.

The site of incision. This is made at the point of maximum protrusion, usually

between the uvula and the second upper molar tooth. A test aspiration may be

made on occasion before the incision. A long-handled pointed scalpel is used for

the incision. All but 1,5 to 2 cm of the point is wrapped in sterile adhesive

tape to prevent the point of the scalpel from penetrating too deeply and

injuring the major vessels of the neck. The incision is made parallel to the

ascending ramus of the mandible and must not pass externally since the internal

carotid artery and internal jugular vein are immediate relations. If the

diagnosis is correct, pus gushes out and must be removed with a powerful

aspirator to prevent aspiration into the trachea. After the abscess has drained,

a hemostat is introduced into the abscess cavity and opened widely usually

producing a further gush of pus. The abscess cavity must be opened up daily

until pus no longer drains from it.

An incision should not be made until the abscess is “ripe”, i.e., fluctuation

can be shown or is probable.

Course and prognosis. Regression of the inflammation and prevention of an

abscess is possible with timely administration of antibiotics. An abscess may

also drain spontaneously and heal. However, distressing pain and difficulty in

eating usually require active drainage. If tonsillectomy is not carried out,

there is a high risk of recurrent abscess in the paratonsillar scar tissue.

Complications and dangers. These include extension of the inflammatory swelling

and edema to the laryngeal inlet with increasing respiratory obstruction and

possibly danger of asphyxia. The abscess may also rupture into the

parapharyngeal space. From here it may extend

- A descending internal cervical phlegmon

- A parapharyngeal abscess

- An ascending involvement of the orbit or the cranial cavity causing

meningitis, cavernous sinus thrombosis, and brain abscess

- Thrombosis of the internal jugular vein

- Erosion of the carotid artery or its branches (rarely)

- Invasion of the parotid (purulent parotitis).

 

RARE ABSCESSES IN THE PHARYNGEAL AREA INCLUDE:

 

Retropharyngeal Abscess in Children

 

An abscess may form by breaking down of lymphadenitis of the retropharyngeal

lymph nodes after pharyngeal infection in children especially in the first 2

years of life.

Symptoms. These include swelling of the posterior pharyngeal wall, difficulty in

swallowing, thick speech, difficulty in eating, elevated temperature, relieving

posture of the neck (differential diagnosis: torticollis), leakage of food

through the nose, possibly nasal obstruction, croup, and laryngeal edema.

Differential diagnosis. Benign and malignant prevertebral tumors must be

considered.

Treatment. This is by paramedian incision and drainage with the head hanging if

fluctuation occurs. The patient must be protected from aspiration and is given

antibiotic cover

 

Retropharyngeal Abscess in Adults

 

This is usually a descending prevertebral cold abscess originating from

tuberculous canes of a cervical vertebra or of suppuration in osteomyelitis of

the temporal bone, e.g., petrositis, and in mastoiditis.

Symptoms. These include pressure in the neck, attacks of coughing, difficulty in

swallowing, mild dysphagia, stiffness of the neck, and typical lesions of the

cervical spine on radiographs.

Differential diagnosis is benign and malignant tumors and spondylosis of the

cervical spine.

Treatment. A test aspiration is made. If a cold abscess is present it is

drained, if possible to the lateral part of the neck and not into the

oropharynx. Antituberculous treatment is given, and the patient is referred to

an orthopedic surgeon.

 

OTHER PHARYNGEAL INFLAMMATIONS

 

Acute Catarrhal Pharyngitis

 

Symptoms. These include pain on swallowing, possibly radiating to the ear, a

feeling of dryness, heat, and soreness in the pharynx, itching, scratching,

burning, clearing the throat, and attacks of coughing. The patient usually feels

sick. The entire pharynx (naso-, oro-, and hypopharynx), is usually involved in

the infection. Fever occurs, especially in children.

Pathogenesis. This is usually a primary virus infection often with later

secondary bacterial infection. Less often it is a primary bacterial infection

due to streptococci, hemophilus influenza, or pneumococci. There are prodromal

symptoms on acute infection such as measles, scarlet fever, and rubella. An

acute pharyngitis may also be caused by physical or chemical injury, scalds,

caustics, etc.

Diagnosis. The mucosa appears red and thickened. The palatal and pharyngeal

mucosa are dry with a glazed surface. Mucus is produced which is initially

colorless but later tenacious and yellow. Deep-red, solitary follicles are

usually prominent, and there is a regional lymphadenopathy with swelling and

tenderness, especially in children. Tonsillitis often occurs, or if the tonsils

have been removed there is infection of the lateral bands.

Treatment. Symptomatic treatment includes hot milk and honey, cold or warm

cervical dressings, pharyngeal irrigation, and steam inhalations. Smoking is

forbidden, and anesthetic and disinfectant lozenges are given. Parenteral

antibiotics are only given for severe bacterial infections. Bed rest is advised

for fever.

 

Chronic Pharyngitis

 

This is a comprehensive term for several chronic irritative or inflammatory

conditions of the pharyngeal mucosa.

Symptoms. There are several forms.

1. Simple chronic pharyngitis. This causes a globus sensation, constant throat

cleaning, bouts of coughing, a feeling of dryness or phlegm in the throat, pain

in the neck and on swallowing of varying degree, and tenacious secretion. The

course is intermittent, and there is no generalized upset and no fever.

2. Chronic hyperplastic pharyngitis. The mucosa of the posterior pharyngeal wall

is thickened and granular with prominent solitary follicles. It is a smooth red

to greyish-red in color, possibly with venous telangiectasis and secretion of

stringy colorless mucus. There is usually a very disturbing, strange sensation

in the pharynx with compulsive throatclearing and swallowing, gagging, and even

vomiting.

3. Chronic atrophic pharyngitis. The posterior pharyngeal wall is dry, glazed

often with dry, tough crusts of secretion. The mucosa is smooth, pink, often

very tender and transparent, but may also be red and thickened. Simultaneous

atrophic rhinitis and laryngitis sicca may occur. The patient is constantly

obliged to spit out the stringy secretion. At night there is a feeling of

choking and disturbance of sleep. Continuous clearing of the throat may produce

slight mucosal hemorrhage. The disease depends on climatic or temperature

conditions, and the symptoms resolve at the seaside but are worse in hot dry

air. Older people are more often affected.

Pathogenesis. The patient often has a constitutionally determined functional

weakness of the mucosa. On the other hand, the disease may be due to chronic

exogenous damage from dust, chemicals, heat (e.g., at work), marked changes in

temperature, and working in drafty and smoky conditions (butchers and restaurant

personnel), and dry or incorrectly air-conditioned atmosphere, marked nicotine

and alcohol abuse, mouth breathing, nasal obstruction, abuse of nose drops,

chronic sinusitis, and adenoidal hypertrophy. Other causes include endocrine

disorders (menopause, hypothyroidism), avitaminosis A and general disorders

(heart and kidney malfunction, diabetes, pulmonary insufficiency, chronic

bronchial diseases). Finally, mucosal allergy and incorrect use of the voice in

professional speakers such as teachers, politicians, and singers may be

responsible.

Diagnosis. The local findings are typical. The disease lasts for years with an

intermittent course. There is often a discrepancy between the unremarkable local

findings and the marked symptoms.

Treatment. The above-named local or distant causes are looked for and

eliminated.

Symptomatic treatment includes moisturizing of the pharyngeal mucosa by steam

inhalations. Nicotine and alcohol must be avoided. Local measures are include

oily preparations to provide a protective film for the dry mucosa. A change of

climate is advised, and the air humidity at work is tested. The patient may even

have to change his job or place of residence.

 

 

Part 8

 

DISEASES OF THE LARYNX

 

Acute laryngitis

 

Symptoms. These include hoarseness, aphonia, pain in the larynx, and coughing

attacks. In children there is a danger of airway obstruction. Acute laryngitis

is usually due to ascending or descending infections from other parts of the

airway. Fever can take place.

Pathogenesis. The cause is viral or bacterial infection, although thermal,

allergic, or inhaled chemical toxins may occasionally be responsible.

Diagnosis. There is reddening of the tip of the epiglottis and there may be some

slight oedema. The arytenoids are reddened and also show some swelling. Oedema

and flushing of the false cords may be one of the most marked features of the

infection. The false cords may be so swollen that they conceal the true cords

beneath. The true cords will appear watery. They are thickened and rounded;

their colour may vary from a slight pink to a bright red, the reddening being

most marked at first at the part of the cord farthest from the free edge.

Movement of the cord may be restricted owing to the swelling of the surrounding

parts, but the movement is equal and there is no paralysis. The whole larynx

shows the presence of hypersecretion, and the vocal cords may be covered with

mucus or pus. Depending on the underlying disease, the neighboring pharyngeal or

tracheal mucosa, may also be inflamed.

Treatment. Since viral infections are often followed by secondary bacterial

infection, antibiotics are indicated. Steroids are also indicated for marked

edema. General measures include steam inhalation, infusion of the solutions,

which contains Ectericide, Hydrocortizone by special laryngeal syringe into the

larynx.

Voice rest is indicated, and smoking should be forbidden. Chemicals such as

certain dyestuffs or artificial products and allergic toxins such as hair

sprays, shellfish, and crustaceans should be eliminated.

If the symptoms do not improve considerably or resolve within 3 weeks,

telescopic or microlaryngoscopy is indicated to exclude other laryngeal

diseases. Ulceration, proliferation, and exudate are not typical of
