Abstract
|
|
|
Tinnitus is a perception of sounds in the absence of external noise. There are two types of tinnitus, sensorineural and somatic, and somatic tinnitus is usually amenable to treatment. The most common form of somatic tinnitus is a pulsatile tinnitus, which is known to be attributable to turbulent blood flow caused by vascular abnormalities.
However, recent research has demonstrated that structural abnormalities are not mandatory factor to cause pulsatile tinnitus. Here we present a case of pulsatile tinnitus originated from sigmoid sinus (SS), but without definite bony wall dehiscence, which have been treated by transmastoid SS reshaping surgery.
