ENT: rapid revision one-liners for NEET PG
ENT (Otorhinolaryngology) in NEET PG covers ear diseases, nasal and sinus pathology, throat conditions and head and neck tumours. The subject is clinically oriented with questions based on presenting symptoms, examination findings and management.
These one-liners cover the classic associations, investigation of choice and treatment protocols for the most commonly tested ENT conditions.
Must-know one-liners
- Otitis media with effusion (glue ear) is the most common cause of conductive hearing loss in children
- Cholesteatoma is a keratinising squamous epithelium in the middle ear; it is locally destructive and not a true tumour
- Attic perforation (posterosuperior marginal) with cholesteatoma is unsafe type of chronic suppurative otitis media (CSOM)
- Tubotympanic type (central perforation, mucosal disease) is the safe type of CSOM
- Modified radical mastoidectomy is the surgery for cholesteatoma (canal wall down procedure)
- Otosclerosis causes conductive hearing loss due to stapes fixation; Carhart notch at 2 kHz on audiometry is characteristic
- Stapedectomy (or stapedotomy) is the definitive treatment for otosclerosis
- Schwartz sign (flamingo-pink tympanic membrane due to increased vascularity of promontory) is seen in active otosclerosis
- Rinne test is negative in conductive hearing loss (bone conduction > air conduction); positive in normal hearing and sensorineural hearing loss
- Weber test lateralises to the affected ear in conductive hearing loss and to the better ear in sensorineural hearing loss
- Acoustic neuroma (vestibular schwannoma) is the most common tumour of the cerebellopontine angle
- Acoustic neuroma: earliest symptom is progressive unilateral sensorineural hearing loss; MRI with gadolinium is the investigation of choice
- Meniere disease presents with the triad of episodic vertigo, fluctuating sensorineural hearing loss and tinnitus; low-frequency hearing loss initially
- BPPV (benign paroxysmal positional vertigo) is the most common cause of peripheral vertigo; diagnosed by Dix-Hallpike test and treated with Epley manoeuvre
- Ototoxic drugs: aminoglycosides (cochlear and vestibular), loop diuretics, cisplatin, aspirin (reversible at high doses)
- Rhinitis medicamentosa is rebound nasal congestion from prolonged use of topical nasal decongestants (oxymetazoline, xylometazoline)
- Antrochoanal polyp is a unilateral polyp arising from the maxillary sinus in young adults; benign, treated by Caldwell-Luc or endoscopic surgery
- Ethmoidal polyps are typically bilateral and associated with allergy and asthma; Samter triad = nasal polyps + asthma + aspirin sensitivity
- Inverted papilloma is a benign but locally aggressive tumour of the lateral nasal wall; has malignant potential (squamous cell carcinoma)
- Juvenile nasopharyngeal angiofibroma is a benign vascular tumour occurring exclusively in adolescent males; presents with unilateral nasal obstruction and recurrent epistaxis
- Epistaxis: Little area (Kiesselbach plexus) on the anterior nasal septum is the most common site of bleeding
- Posterior epistaxis is more common in elderly and hypertensives; may require posterior nasal packing or sphenopalatine artery ligation
- DNS (deviated nasal septum) is corrected by septoplasty (SMR -- submucous resection -- is the older procedure)
- CSF rhinorrhoea: fluid tests positive for beta-2 transferrin (most specific test) or glucose (less specific)
- Atrophic rhinitis (ozaena) causes foul-smelling nasal crusting; paradoxically, the patient cannot smell it (anosmia)
- Acute epiglottitis is most commonly caused by Haemophilus influenzae type b; presents with stridor, drooling and thumb sign on lateral X-ray
- Croup (acute laryngotracheobronchitis) is most commonly caused by parainfluenza virus; steeple sign on AP X-ray
- Reinke oedema is subepithelial oedema of the vocal fold (Reinke space); caused by smoking and voice abuse
- Vocal cord nodules (singer nodules) are bilateral, at the junction of anterior one-third and posterior two-thirds of the vocal cord
- Vocal cord polyps are usually unilateral; may occur at any site on the vocal cord
- Recurrent laryngeal nerve palsy causes vocal cord paralysis in the paramedian position; bilateral paralysis causes stridor
- The most common malignant tumour of the larynx is squamous cell carcinoma; glottic carcinoma has the best prognosis (early voice change, low metastatic rate)
- Supraglottic carcinoma has a higher rate of cervical lymph node metastasis than glottic carcinoma
- Tracheostomy is performed between the 2nd and 3rd or 3rd and 4th tracheal rings
- The most common complication of tracheostomy is haemorrhage (immediate) and tracheal stenosis (late)
- Ludwig angina is a bilateral submandibular space infection; airway management is the priority
- Quinsy (peritonsillar abscess) causes trismus, unilateral tonsillar swelling with uvular deviation; treated by incision and drainage
- Nasopharyngeal carcinoma is associated with EBV and is common in Chinese populations; elevated EBV VCA IgA antibodies aid diagnosis
- Parapharyngeal abscess pushes the tonsil medially; retropharyngeal abscess causes neck stiffness and dysphagia in children
- Pleomorphic adenoma is the most common tumour of the parotid gland; treated by superficial parotidectomy with facial nerve preservation
- Warthin tumour (papillary cystadenoma lymphomatosum) is the second most common parotid tumour; bilateral in 10% of cases
- Frey syndrome (gustatory sweating) is a complication of parotid surgery due to aberrant regeneration of parasympathetic nerve fibres
- Branchial cyst (second arch) presents as a painless swelling anterior to the upper third of the sternocleidomastoid in young adults
- The most common foreign body site in the oesophagus is the cricopharyngeal sphincter (C6 level)
- The most common foreign body in the bronchus in children is peanut; goes to the right main bronchus more often
- Gradenigo syndrome: otitis media + CN VI palsy + retro-orbital pain (petrous apex involvement)
- Presbycusis: age-related sensorineural hearing loss; bilateral, progressive, high-frequency loss
- Mucocele of the paranasal sinuses most commonly involves the frontal sinus
- Laryngocele is an abnormal dilatation of the laryngeal saccule; may be internal, external or combined
- Killian dehiscence (between the thyropharyngeus and cricopharyngeus) is the site of pharyngeal (Zenker) diverticulum
How to use these one-liners
ENT one-liners work best when grouped by anatomical region: ear (otology), nose (rhinology) and throat (laryngology). For each condition, try to recall the classic presentation, investigation of choice and definitive management.
Pay special attention to the differentiation between safe and unsafe CSOM, types of hearing loss (conductive vs sensorineural) and causes of stridor in children vs adults.
Key mnemonics
Samter triad: nasal polyps + asthma + aspirin sensitivity (also called aspirin-exacerbated respiratory disease).
Carhart notch at 2 kHz = otosclerosis (C for Carhart, 2 for 2 kHz).
Little area = Kiesselbach plexus: both names for the most common site of epistaxis on the anterior nasal septum.
Revision schedule
ENT is a relatively compact subject. Revise these one-liners every 3-4 days, alternating between otology and rhinology/laryngology. In the final week, one complete run-through daily is sufficient. Focus extra time on hearing tests (Rinne, Weber, audiometry patterns) and causes of stridor.
Frequently Asked Questions
How many ENT questions appear in NEET PG?
Typically 8-12 questions. Otology (CSOM, otosclerosis, hearing tests), rhinology (polyps, epistaxis) and laryngology (vocal cord lesions, laryngeal carcinoma) are the most commonly tested areas.
Are hearing test interpretations commonly asked?
Yes, Rinne and Weber test interpretation is a classic NEET PG question type. Know how to differentiate conductive from sensorineural hearing loss using these tests and audiometry patterns.
How important are head and neck tumours for NEET PG?
Salivary gland tumours (pleomorphic adenoma, Warthin tumour), nasopharyngeal carcinoma and laryngeal carcinoma are all commonly tested. Know the tumour type, location and management.
Should I focus on surgical procedures?
Know the indications and basic principles of key procedures: tympanoplasty, mastoidectomy, stapedectomy, septoplasty, FESS, tracheostomy and parotidectomy. Detailed operative steps are usually not asked.
