B Schwartz's sign is usually present in the tympanic membrane

C Low frequency sensorineural deafness is often seen in pure tone audiogram

D Decompression fallopian canal is the treatment of choice

Ans. C Low frequency sensores neural deafness is often seen in pure tone audiogram

Ref. Dhingra 5th/ed p 77 3, 6th/ed p 707

a. Carharts' Notch and Schwartz's sign are seen in otosclerosis - Dhingra 5/e pg-98-99, 6/e p87

b. Decompression of endolymphatic sac (and not fallopian canal) is done in Menieres disease. - Dhingra 5/e pg-7 76, 6/e p 704

c. Decompression of Fallopian canal is done in traumatic facial nerve palsy.

d. Meniere's disease is associated with - SNHL which affects low frequencies first, followed by higher frequencies later. This is visible on pure tone audiogram.

Also Know

a. Conductive deafness often involves all frequencies (high as well as low) whereas sensorineural hearing loss such as presbycusis affects higher frequencies more than lower frequencies. Meniere's disease is an exception which affects lower frequencies more.

b. Hennebert's sign: False positive fistula test is seen in Meniere's disease.
