ENT Signs

·         BATTLE SIGN- Bruising behind ear at mastoid region, due to petrous temporal bone# (middle fossa #)

·         BOCCA'S SIGN - Absence of post cricoid crackle(Muir's crackle) in Ca post cricoid

·         BROWN SIGN—blanching of redness on increasing pressure more than systemic pressure see in glomus jugulare

·         BOYCE SIGN - Laryngocoele-Gurgling sound on compression of external laryngocoele with reduction of swelling

·         DODD’S SIGN/CRESCENT SIGN - X-ray finding-Crescent of air between the mass and posterior pharyngeal wall. positive in AC ployp Negative in Angiofibroma

·         FURSTENBERGERS SIGN-This is seen when nasopharyngeal cyst is communicating intracranially,there is enlargement of the cyst on crying and upon compression of jugular vein.

 ·         HITSELBERGER'S SIGN - In Acaustic neuroma- loss of sensation in the ear canal suppllied by Arnold's nerve( branch of Vagus nerve to ear )
·
         HOLMAN MILLER SIGN, ANTRAL SIGN-it is seen in angiofibroma,the tumor pushes forward on the posterior wall of the maxillary sinus..

·         HONDOUSA SIGN--X-ray finding in Angiofibromaindicating infratemporal fossa involvement characterised by widening of gap between ramus of mandible and maxillary body.

·         HENNEBERT SIGN- false fistula sign( cong.syphilis, Meniere's,)

·         IRWIN MOORE’S SIGN-------- positive squeeze test in chronic tonsillitis

·         LIGHT HOUSE SIGN--- seeping out of secretions in acute OTITIS media

·         LYRE'S SIGN - splaying of carotid vessels in carotid body tumor

·         MILIAN’S EAR SIGN- Erysipelas can spread to pinna(cuticular affection), where as cellulitis cannot.

·         PHELP'S SIGN - loss of crust of bone between carotid canal and jugular canal in glomus jugulare

·         RACOON SIGN-Indicate subgaleal hemorrhage,and not necessarly base of skull #

·         STEEPLE SIGN- X-ray finding in Acute Laryngo tracheo bronchitis

·         STANKIEWICK'S SIGN - indicate orbital injury during FESS. fat protrude in to nasl cavity on compression of eye ball from ouside

·         TRAGUS SIGN- EXTERNAL OTITIS , Pain on pressing Tragus

·         TEA POT SIGN is seen in CSF rhinorrhoea..

·         WOODS SIGN----- palpable jugulodigastric lymphnodes

·         Pseudohypacusis is defined as functional hearing loss. Occasionally, patients willfully or subconsciously exaggerate their hearing loss. The signs in test behavior that suggest a functional component include (1) inconsistent responses, (2) significant differences between the thresholds obtained using ascending and descending administration of test stimuli, (3) a discrepancy of more than 8 dB between the SRT and the pure-tone average of 500–2000 Hz, and/or (4) a positive Stenger test. The Stenger test may be used to identify unilateral or asymmetrical functional hearing loss. It is based on the concept that when both ears are stimulated simultaneously by a tone equal in frequency and phase, the auditory percept is lateralized to the ear with better hearing. Systematic manipulation of the relative intensities delivered to each ear provides the audiologist with an estimate of the true threshold in the ear that has a more significant hearing loss. When speech stimuli are used, the test is called a Speech Stenger test or a Modified Stenger test. Other objective measures that may disclose functional involvement include acoustic reflexes, auditory brainstem responses, and otoacoustic emissions.
