OBJECTIVE: To evaluate clinical characteristics and present surgical outcomes of
PT caused by sigmoid sinus wall dehiscence (SSWD). METHODS: This study
retrospectively reviewed 34 patients with PT who were diagnosed with SSWD in our
institution between December 2008 and July 2013. Among them, 27 patients
underwent sigmoid sinus wall reconstruction (surgery group) and 7 patients
refused surgery (non-surgery group). Preoperative data were obtained from the
patients' medical records. All patients were followed up regularly for at least
25 months. Preoperative and postoperative computed tomography angiography (CTA)
images were compared. Student's t-tests were used to compare age, body mass index
(BMI) and preoperative Tinnitus Handicap Inventory (THI) scores between the
surgery and the non-surgery groups and to compare pre- and follow-up THI scores.
RESULTS: There was no significant difference in age, body mass index, or
preoperative THI scores between groups. Following surgery, 14 patients had
complete resolution, 5 had partial resolution, 7 experienced no change and PT was
aggravated in 1 patient. The difference between preoperative and postoperative
THI scores was significant. No severe complications were found postoperatively.
Comparison of the preoperative and postoperative CTA images revealed that remnant
unrepaired dehiscences were the cause of unsatisfactory outcomes following
surgery. In the non-surgery group, PT remained largely unchanged. CONCLUSIONS:
Sigmoid sinus wall reconstruction is an effective and safe treatment for PT
caused by SSWD. It is imperative that all regions of the dehiscence are
sufficiently exposed and resurfaced during surgery.
