n Flashcards
Enumerate the 6 features in the medial wall of the middle ear
Promontory: first basal turn of cochlea
Oval window
Round window
Transverse part of facial nerve
Sinus tympani (depression between oval and round window)
Process cochleariform
Give the treatment for Otomycosis
Local EAC cleaning with ear wash
Antifungal drops like Nystatin and Salicylic acid 2% + Alcohol 70%
Packing EAC with antifungal cream on gauze if resistant
Symptoms and signs of meningitis
Signs: neck rigidity, painful neck flexion, restlessness, photophobia, projectile vomiting, blurring of vision and severe headache that is persistent
Signs:
-Kernig’s sign: Patient is asked to lie in supine position; with hip and knee flexed–> He can not do extension
-Brudzinski’s sign: Flexion of the neck will be accompanied with reflex flexion of hip and knee
Investigations and treatment of meningitis
Investigations: CT to exclude brain abscess and Lumber puncture for CSF analysis
Treatment: Hospitalization in semi-dark room, Systemic antibiotics that cross BBB like 3rd or 4th gen cephalosporin IV, Dehydrating measure like mannitol to decrease ICT
Surgical: treatment of the cause—> if cholesteatoma; mastoidectomy
Compare between clinical pictures of UMNL and LMNL facial paralysis
Enumerate the cranial (4) and extracranial (6) complications of cholesteatoma
Cranial: Mastoiditis, Labyrinthitis, Petrositis, Facial paralysis
Intracranial: Extradural, Subdural, Brain abscess, Meningitis, Lateral sinus thrombosis, Otitic Hydrocephalus
Enumerate the indications (4) and contraindications (4) of the ear wash?
Wax deafness
Non impacted foreign body
Fungal mass
Caloric test
TM perforation
Vegetable foreign body
Bacterial otitis externa
Fistula between middle and inner ear
Investigations and treatment of nasal fracture
Investigations: X-ray
Control of epistaxis if present. Reduction of bone right away if no edema under general anesthesia.
If edema, wait a week.
If he came after 2 weeks, wait for 3 months and do rhinoplasty
After fixation, anterior nasal packing to stop any bleeding and support for 48hrs
Fixation from outside with aluminum sheet for 2 weeks
Anti biotics analgesics and anti-inflammatory
Oro-antral fistula, Symptoms, signs and investigations
Symptoms:
Unilateral regurgitation of food and fluid
Unilateral offensive nasal discharge
Discharge through the fistula to the mouth
Fistula is seen through oral cavity
CT shows sight of fistula
Treatment of Oro-antral fistula
Recent case (24 h after dental extraction): small fistula heals spontaneously and large fistula needs surgical closure
Old case: Radical antrum operation
Maxillary sinusitis symptoms and signs
History of dental operations, nasal discharge can be offensive
pain over cheeks referred to teeth and ears
Tenderness over cheeks, and discharge from posterior part of middle meatus
Sinusitis investigations
Xray sinus view shows opacity or fluid level
Culture and sensitivity of discharge
CT if chronic or recurrent case: mandatory preoperative investigation
Sinusitis treatment
Complete bed rest with plenty of warm fluids. Systemic antibiotics according to culture and sensitivity. Analgesic, antipyretic and decongestant nasal drops. Steam inhalation
If fail treatment then surgical: Functional endoscopic Sinus Surgery (FESS)
Causes of watery discharge 5
Acute non-specific rhinitis
Allergic rhinitis

Excessive lacrimation
CSF rhinorrhea
4 causes of water and food discharge
Perforated palate (syphilis)
Cleft palate
Paralysis of soft palate
Oro-antral fistula
3 causes of crusty nasal discharge
Atrophic rhinitis
All granulomas
Septal perforation
Discuss briefly the investigations and treatment of Choanal Atresia
Investigations: CT: differentiated bony from membranous atresia
Treatment
1. Unilateral: Operation is not urgent to be done in the neonatal age, so it is postponed for 2-3 years
2.Bilateral: It is an emergency situation
Saving the airway: keeping the mouth open by either:
- Plastic oral airway
- Endotracheal intubation
> Operation:
- Trans-nasal by endoscope
Enumerate local causes of Epistaxis (9)
Idiopathic: commonest cause
Trauma: Foreign bodies
Inflammations: Acute or chronic rhinitis
Neoplastic: malignant or benign tumors

Environmental factors: allergens, humidity
Enumerate systemic causes of Epistaxis 4
Systemic hematologic, hepatic, renal or genetic disease
Long term anti-coagulant use
Hypertension
Coagulation disorder like hemophilia
Explain the three stages of Rhinoscleroma
Atrophic stage: obstruction, discharge, epistaxis. Roomy cavity, atrophic mucosa and turbinates
Active nodular stage: Bilateral obstruction and discharge. Bilateral masses and Russel bodies and Mikulicz cells are detected
Fibrotic stage: Obstruction and deformity
