DESCRIPTION
Bedside Cases Flash CardsTRANSCRIPT
ENT OSCE 2012 at PMC. Questions were made by RCSI. Just remember that there will be questions for each ENT components. For example here we have 2 nasal questions (saddle nose, septal hematoma), 3 ear questions(cauliflower ear, middle ear effusion, hearing loss/audiogram), 2 oral/throat questions(tongue cancer, submandibular stone), 3 head and neck questions (facial palsy, tracheostomy, laryngectomy). The questions I wrote back here may not be complete since I could not recall everything, but hopefully it will still be helpful and you guys can figure out the rest.
1. Saddle nose, deviated nose a. Signs/symptoms: nasal obstruction, cosmetically complaint,
anosmia b. Cause = trauma, cancer, infection(syphilis, leprosy), relapsing
polychodritis, wegeners granulomatosis,ectodermal dysplasia c. Complication d. Treatment: rhinoplasty e. Define oezena = atrophic rhinitis. Caused by klebsiella.
i. Primary due to infection?? ii. Secondary due to work related, trauma
f. Smell and taste come together. If can’t smell, can’t taste.
2. Nose growth/mass/polyps? Is actually septal haematoma a. Symptoms – nasal obstruction, bleeding, anosmia b. Rx: incision and drainage, cover with IV antibiotic to prevent
saddle nose? c. Complications: abscess, saddle nose, septal perforation(if cartilage
only affected), fibrosis/septaldeviation d. Name 2 structures of cartilage
3. Granulomatous disease : TB, sarcoidosis, toxoplasmosis, wegener’s
a. Actinomcosis silvr stain b. Aetiology: poor dental hygiene, post radiation,
immunocompromised c. Rx: antibiotic (penicillin), surgical debridement d. it was actinomycosis.description were non-‐caseating granuloma,
multiple sinus with discharge, sulphur granules found in pus e. differentials – cellulitis, furunculitis, carbuncle, sebaceous cyst
4. Cauliflower ear(auricular haematoma) due to trauma
a. Microtia: congenital b. Common in where: boxing or sport injury? Also wrestler
5. Middle ear effusion
a. Can see air bubble b. Rx: medically for 3 months. c. Causes: allergic rhinitis, passive smoking, not breastfed d. Grommet inserted at infant?
e. Temporofascia for tympanic membrane surgery?
6. Upper facial nerve palsy a. Has not cross, so forehead sparred b. Other associated symptoms of facial nerve palsy
i. Metallic taste (altered taste) ii. Hearing very loud sound (due to stapedius muscle palsy) iii. Decrease lacrimation
c. Ramsay hunt syndrome. = herpes zoster otticus d. Classification of facial nerve palsy : House-‐Brackmann
classification
7. Electric larynx, surf box, iesophageal voice?? a. Laryngectomy : no sound production
i. Cant taste (because no linear of air?) ii. Constipation iii. Cant dliver baby iv. Difficulty in lifting heavy weight
1. All because unable to increase intraabdominal pressure
8. Pre-‐malignant condition for tongue cancer: erythroplakia, leukoplakia,
non healing ulcer a. Ix: biopsy, CT b. Aetiology: STD, sharp tooth, smoking, alcohol, betel nut c. Rx: surgery, radiotherapy d. Classification: TNM
9. Tracheostomy with tube
a. Indications – i. upper airways blockage, ii. assist ventilation iii. decrease dead space, eg: end stage COAD, iv. forn bronchial toilet? In semiconscious/unconscious
patient v. prophylaxis vi. stroke, vii. laryngectomy
b. Complications – i. Tube dislodge ii. Bleeding iii. Tube going to wrong place/ false track iv. Pneumothorax v. infection, vi. inner tube-‐ can be taken out and washed (to prevent block
due to phlegm) vii. to do tracheostomy:
1. skin 2. split strap muscle
3. divide isthmus of the thyroid 4. make hole at neck = tracheostomy
c. Where do you insert endotracheal tube in patient with laryngectomy
d. How to make it not move or stay still in position e. Tracheostomy hole
i. Is it permanent?
10. Submandibular stone a. Symptom: pain on eating (due to saliva can’t flow), swelling during
eating b. Rx: sialodonoscopy, remove the whole gland c. Neural complication in patient????
i. Marginal mandibular? ii. Hypoglossal iii. Lingual (supply sensation of tongu. Risk chewing out of own
tongue??) d. Rx: antibiotic, painkiller, antiinflammatory e. Lesion indicates tumour? f. Name the gland most commonly affected g. Name the structure? Submandibular duct, Wharton’s duct
11. Pure tone audiometry
a. Occupational deafness b. Noise-‐induces sensorineural loss – because there was no air-‐borne
gap on the audiometry and there was a dip at 4000hz c. Why 4000 Hz?
Here are the list of topics need to be covered: 1. Facial trauma
a. Saddle nose b. Septal hematoma c. Fractured nasal bone
