Study Notes
ENT Clinics and Schedule
- Jolly-Radiology and ENT Clinic sessions are segmented into two groups, A and B.
- Dr. R. Forde oversees the DERM outreach clinics, occurring weekly for all students.
- DERM clinics at various locations are held on designated Tuesdays and Fridays throughout the month.
Otitis Externa vs. Otitis Media
-
Otitis Externa:
- Severe otalgia that does not decrease with otorrhoea onset.
- Otorrhoea without mucus.
- Mild hearing loss.
- Significant pain when pressing on the tragus or moving the pinna.
-
Otitis Media:
- Otalgia reduces significantly with early onset of otorrhoea.
- Discharge is mucopurulent.
- Mild to moderate hearing loss.
- Pain is unrelated to pinna movement.
Pathogenesis of Middle Ear Infections
-
Dysfunction of the eustachian tube leads to:
- Poor middle ear ventilation.
- Pressure imbalance with atmospheric pressure.
- Accumulation of middle ear secretions.
- Risk of nasopharyngeal infections ascending via the eustachian tube.
-
Common causes of eustachian tube obstruction include:
- Adenoidal hyperplasia in children.
- Congenital cysts.
- Angiofibromas in male teenagers, potentially leading to severe epistaxis.
- Nasopharyngeal carcinoma, which may obstruct eustachian tube drainage.
Cholesteatoma
-
Cholesteatoma can arise from:
- Penetrating injuries or surgical procedures affecting the tympanic membrane.
- Congenital cohort, where epithelial rests are trapped.
-
Complications of cholesteatoma:
- Hearing loss due to ossicular disruption and middle ear exudate.
- Facial nerve palsy and various abscess formations.
- Potential for meningitis and intracranial complications.
Malignant Otitis Externa
-
Often occurs in elderly diabetics, characterized by:
- Purulent otorrhoea and disproportionate otalgia, worsened at night.
- Granulation tissue at the osseo-cartilaginous junction in the external auditory canal.
- Conductive hearing loss.
-
Pseudomonas aeruginosa is frequently implicated as the causative organism.
-
Affected cranial nerves may lead to complications like osteomyelitis.
Nasopharyngeal Carcinoma
-
A malignant epidermoid tumor, predominantly found in specific ethnic groups such as Cantonese Chinese.
-
Incidence rates vary regionally, with high rates in Southern China compared to low rates in Caucasians.
-
Key statistics:
- Hong Kong: 26 per 100,000 males.
- Jamaica: 1.4 per 100,000 males; 0.5 for females.
- Incidence peaks in the 4th decade of life in high-risk areas.
-
Aetiology involves genetic, viral, and environmental factors, highlighting the complex nature of carcinogenesis in this type of cancer.
