Laryngocele
Causes of Neck Lumps
Laryngocele :
Air filled sac associated with larynx becomes dilated
High pressure in larynx pushes laryngeal mucosa through
thyrohyoid membrane
Found in wind instrument players
Symptoms include:

Thyroglossal Cyst :
Arise from persistent epithelial thyroid duct formed with the
descent of thyroid from foramen caecum to its final position
in the front of the neck
Occur at any age, but commonly between 15 – 30 yrs of age
Presents with painless smooth cystic midline swelling in
region of hyoid bone
Cyst rises when the patient protrudes their tongue

Branchial Cyst:
Arises from embryonic remnants of second branchial cleft in
the neck
Most common in young adults
Presents as smooth swelling in front of the anterior border of
sternomastoid, at the junction of upper and middle thirds
Treatment is by excision
Treatment may need to be delayed if cyst is acutely infected,
leading to branchial fistula

Quinsy
Diagnosis of ENT Diseases

Quinsy :
Diagnosis of ENT Diseases










Quinsy :
Aka peritonsillar abscess
Complication of acute tonsillitis
Usually due to streptococcal infection
Collection of pus arising outside tonsil capsule.
Symptoms include: sore throat, fever, halitosis, dysphagia,
trismus, referred ear ache.
Uvula may be very oedematous and displaced downwards
and medially by the infected tonsil
Treatment is with penicillin based antibiotics ( IV
Benzylpen, or oral penicillin V, + IV hydrocortisone)
Drainage of abscess by aspiration or incision
Consider tonsillectomy 6 weeks post acute infection

Diagnosis of ENT Diseases

Otitis Externa :
Diagnosis of ENT Diseases
Otitis Externa :
Causes :





Infection – bacteria (esp staph), fungi
Allergy – eczema, contact allergy
Iatrogenic – frequent ear syringing, trauma
Swimmers more commonly affected
Symptoms – irritation, discharge, pain, hearing loss
Refer to hospital if :






Malignant otitis externa
Uncontrolled symptoms
Previous history of complex ear problems
Treatment:




Antibiotic eardrops +/- oral fluclox
Aural toilet
If symptoms not resolving after 1/52, consider alternative drops +/erythromycin









Malignant Otitis Externa :
Otitis externa that has spread to cause osteomyelitis of skull
base
Due to Pseudomonas aeruginosa and anaerobes
Facial nerve involved in 50% of cases
Granulation tissue - diagnostic indicator
Ix – swabs for cultures, and CT/MRI to show invasion
IV cipro or ceftazidine + metronidazole
Surgical removal of granulated tissue may be needed
Diagnosis of ENT Diseases

Otitis Media
Diagnosis of ENT Diseases
Otitis Media :
Inflammation of middle ear
Classified as :









Acute suppurative – caused by viral or bacterial infection. Causes
pain and tenderness
Chronic suppurative – persistent drainage from ear associated with
TM perforation. Not usually painful due to chronic nature
Serous/secretory – Middle ear effusion without TM perforation.
Associated with dysfunction/obstruction of eustachian tube.
Important cause of hearing loss in children.
Antibiotics used in AOM – Amoxicillin
Tympanoplasty in safe CSOM
Aural toilet, antibiotics, exploration of the ear in unsafe
CSOM
