Figure 1 A typical case of sigmoid sinusoidal tinnitus and low-frequency sensorineural hearing loss (right sigmoid sinus diverticulum [SSD]). (A) Preoperative temporal bone computed tomography (CT). (B) Postoperative temporal bone CT. (C) Preoperative pure-tone audiometry (PTA). (D) Postoperative PTA. (E) Intraoperative SSD. (F) After excision of the sigmoid diverticulum during the operation, the autologous bone powder was covered. In PTA, the dotted red line represents the right side; the star blue line represents the variation of the left.
