Figure 2 A typical case of sigmoid sinusoidal tinnitus and low-frequency sensorineural hearing loss (the defect in the bone wall of the right sigmoid sinus forms a resonating cavity). (A) Preoperative temporal bone computed tomography (CT). (B) Postoperative temporal bone CT. (C) Preoperative pure-tone audiometry (PTA). (D) Postoperative PTA. (E) Resonance cavity formation was observed intraoperatively. (F) After excision of the resonance cavity 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.
