ABOHNS Otolaryngology common mistakes
ABOHNS Otolaryngology · Understand the traps and how to avoid them.
When a vignette describes a unilateral serous middle-ear effusion in an adult, committing to 'otitis media with effusion' and stopping, rather than proceeding to nasopharyngeal evaluation for a mass.
Trainees pattern-match the pediatric OME pathway and anchor on the effusion itself; the adult unilateral effusion is a red flag for nasopharyngeal carcinoma and the exam tests whether you escalate.
What to do instead
Build a reflex rule: adult + unilateral effusion = mandatory flexible nasopharyngoscopy and consider imaging before any tube is placed. Practice writing the next-step answer explicitly whenever the effusion is unilateral or persistent.
Selecting the diagnosis that fits the most dramatic symptom (e.g., vertigo) instead of the one that fits the time course and associated findings, such as treating a 20-second positional vertigo as Meniere disease.
Vestibular questions are written with overlapping symptom words; candidates sort on the loudest word rather than on duration, triggers, and audiometric findings.
What to do instead
For every vertigo stem, write down four variables before answering: duration of episodes, trigger (positional vs spontaneous), hearing symptoms, and exam findings. Match the answer to all four, not one.
Choosing 'CT sinuses' as the initial study for uncomplicated acute bacterial rhinosinusitis, or ordering imaging before maximal medical therapy in chronic rhinosinusitis.
Candidates conflate diagnostic workup with surgical planning; CT is a surgical roadmap, not a first-line test for a clinical diagnosis.
What to do instead
Memorize the decision rule: acute bacterial rhinosinusitis is a clinical diagnosis treated empirically; CT is reserved for complications, recurrence after medical therapy, or preoperative planning. State the indication in your answer rationale.
Missing the red-flag combination in a sinus vignette (orbital symptoms, frontal swelling, cranial neuropathy, or fever with severe headache) and answering with oral antibiotics instead of urgent imaging and ophthalmology or neurosurgical involvement.
Complication stems are long and the complication is buried in one clause; candidates focus on the sinus opacification and under-weight the eye or neurologic finding.
What to do instead
Scan every sinus stem for five words: eye, vision, forehead, fever, neuro. If any appear, the answer is imaging plus multidisciplinary urgent management, not outpatient therapy.
Treating a hoarse patient with a normal-appearing larynx on mirror exam as functional dysphonia without visualizing the full larynx, including the anterior commissure and subglottis.
Incomplete visualization is mistaken for a normal exam; the exam tests whether you recognize that inadequate exposure demands a better view.
What to do instead
When the stem says visualization was limited or the anterior commissure was not seen, the correct next step is flexible or operative endoscopy, not a voice diagnosis. Never accept a partial exam as normal.
Under-staging or mis-selecting treatment for a head and neck cancer because the candidate ignores the nodal level or extranodal extension described in the stem.
Candidates focus on the primary tumor size and skim the neck findings; nodal level and extranodal extension drive both stage and adjuvant therapy.
What to do instead
For every oncology stem, extract T, N (with level and extranodal status), and M into a one-line summary before reading the options. If extranodal extension is present, adjuvant chemoradiation enters the differential.
Choosing wide local excision alone for a parotid mass without addressing facial nerve preservation or the role of superficial parotidectomy, and biopsying a parotid mass without considering fine-needle aspiration first.
Candidates reduce the question to 'remove the lump' and skip the anatomic and diagnostic sequence that the exam is actually testing.
What to do instead
Use a fixed parotid algorithm: FNA first, then superficial parotidectomy with facial nerve identification for a typical benign or low-grade lesion. State nerve management explicitly in your rationale.
Managing a pediatric stridor or airway case with the adult reflex (awake intubation or immediate rigid endoscopy) rather than following pediatric airway priorities such as keeping the child calm, avoiding agitation, and proceeding to controlled evaluation in the operating room.
Adult airway algorithms are over-learned and candidates apply them to children without adjusting for smaller margins, higher oxygen consumption, and the risk of precipitating obstruction.
What to do instead
Memorize a separate pediatric airway sequence and rehearse it: minimize agitation, allow spontaneous ventilation, and evaluate in a controlled setting. Flag any answer that involves agitating or paralyzing a child with stridor.
For a thyroid nodule, selecting surgery based on nodule size alone without applying the Bethesda cytology category and ultrasound risk features.
Candidates memorize size cutoffs in isolation and forget that cytology category and ultrasound pattern determine whether to observe, repeat, or operate.
What to do instead
Answer thyroid nodule questions by writing the Bethesda category and ultrasound suspicion first, then applying the management rule for that combination. Size alone is never the whole answer.
Diagnosing 'recurrent infection' in a child with chronic nasal symptoms without considering allergic rhinitis, and ordering antibiotics instead of allergy evaluation.
The infectious framing of the stem pulls candidates toward antibiotics; the allergy domain is tested through the differential rather than the label.
What to do instead
When a pediatric or adult stem lists sneezing, itching, seasonal pattern, or allergic shiners alongside nasal obstruction, put allergy evaluation on the list before antibiotics. Practice stems where the correct answer is 'test for allergy' rather than 'treat the infection'.
