Glomus Tympanicum

We reviewed the clinical characteristics and treatment outcomes of patients with glomus tympanicum tumors (GTTs) presenting with pulsatile tinnitus (PT). We explored whether transcanal sound recording-spectro-temporal analysis (TSR-STA) usefully evaluated changes in PT. The medical records of 13 patients who underwent surgical removal of GTTs were reviewed retrospectively. Two patients underwent preoperative endovascular embolization. Changes in PT, pre- and postoperative audiometry data, TSR-STA results, and clinical outcomes were evaluated. PT was the chief complaint in eight patients (61.5%) and resolved immediately after surgical intervention in all. Two patients exhibited ipsilateral, pseudo-low-frequency hearing loss (PLFHL); surgical GTT removal elicited postoperative improvements in the ipsilesional low-frequency hearing thresholds. Five patients underwent TSR-STA using previously described methods. TSR-STA revealed definite rise-and-fall patterns; surgical tumor removal abated this pattern in one patient, but, for the other four, the patterns did not change greatly post-intervention. Thus, GTT-related PT can be treated successfully (via surgical GTT removal) without complications. In selected cases, preoperative embolization reduces intraoperative hemorrhage. In PT patients with PLFHL, a detailed otoendoscopic examination of the middle ear is required to rule out a GTT. TSR-STA may usefully (and objectively) assess postoperative improvements in GTT-related PT.

Objective: Comprising 4% of tinnitus, pulsatile tinnitus (PT) can be particularly difficult for affected patients as well as surgeons looking to address their symptoms. Often the cause is not identified but can be secondary to turbulent flow in or near the sigmoid sinus, particularly if there is an identifiable sigmoid sinus dehiscence (SSDe) and/or diverticulum (SSDi). These sigmoid sinus wall anomalies (SSWA) may be treated with transmastoid sigmoid sinus resurfacing; however, this intervention remains relatively novel and its technique, materials used, resolution success, and complications need to be continuously reviewed. Methods: A retrospective case series of patients with PT due to SSWA at a tertiary referral center was reviewed. A total of 6 patients (7 ears) treated by transmastoid resurfacing using hydroxyapatite (HA) were retrospectively assessed. Pre-operative demographics and symptoms, pre- and post-operative hearing results, and post-operative outcomes were reviewed. Results: All patients were female with an average BMI of 32.9 (±5.4) and a mean age of 45.5 years (±15.3). Mean follow-up was 648 days. Objective tinnitus was noted in all ears with SSDi (100%); however, no objective tinnitus was noted with purely SSDe. In 100% of ears, PT was diminished with ipsilateral jugular compression and was amplified with contralateral head turn. Pre-operative symptoms of PT resolved in all patients, but delayed recurrence (>1 year) occurred in 1 ear (14%). No patient had pre- or post-operative hearing loss. No major complications were encountered. Conclusions: Transmastoid resurfacing for SSWA with HA bone cement is a safe, reliable intervention in properly identified PT patients.
