PURPOSE: Few studies have examined patients after sigmoid sinus wall reconstruction (SSWR) surgery. The present research seeks to establish a correlation between the SSWR and the long-term recurrence of pulsatile tinnitus (PT), to understand how structural repair affects symptoms.
METHODS: Patients diagnosed with sigmoid sinus wall dehiscence (SSWD), in conjunction with or without concomitant sigmoid sinus diverticulum (SSD), were retrospectively included. Those who underwent SSWR and had both pre- and post-CT arteriography and venography (CTA/V) examination were eventually analyzed in the study. They were classified as a recurrence group and a non-recurrence group based on their follow-up outcomes. The percentage of reconstructed SSWD and SSD was calculated, and the differences between the two groups were compared.
RESULTS: Of the 51 patients, 24 had SSWD only, and 27 had both SSWD and SSD. The recurrence probability was 31.4 %. The presence of preoperative SSD did not affect the outcomes (p = 0.135). SSWD repair degree predicted non-recurrence outcome regardless of SSD (only SSWD: p = 0.049, OR = 1.071, 95 % CI [1.005, 1.46]; SSWD + SSD: p = 0.014, OR = 1.054, 95 % CI [1.011, 1.099]). The Receiver Operator Characteristic curve analysis showed that the SSWD repair degree was a good predictor of non-recurrence. The optimal cut-off values of SSWD repair degree were 71 % and 67 % (only SSWD: AUC = 0.814, p = 0.010, 95 % CI [0.614-1]; SSWD + SSD: AUC = 0.881, p = 0.005, 95 % CI [0.715-1]).
CONCLUSION: During postoperative follow-up, the degree of coverage in the SSWD area is related to the recurrence of SSWR surgery.
