背景资料。虽然颞骨内的空气细胞在脉动性耳鸣(PT)噪声的传递中可能起着重要作用，但尚未有系统的研究。目的。目的探讨乙状窦憩室裂(SSDD)患者与正常对照组颞骨气化度的差异。材料和方法。199例单侧持续性PT伴发SSDD患者和302例对照受试者接受了双期增强CT扫描(DP-CECT)，以评估每只耳的颞骨气化程度。结果。对照组双侧颞骨中，I级16耳，II级53耳，III级141耳，IV级394耳。在199例PT患者的患耳中，I级1耳，II级18耳，III级53耳，IV级12 7耳。虽然颞骨内的气泡是PT发生的重要因素，但其严重程度与健康人的气化症并无显著差异。
Background. Although air cells within temporal bone may play an important role in the transmission of pulsatile tinnitus (PT) noise, it has not been studied systematically. Purpose. To evaluate the difference in temporal bone pneumatization between PT patients with sigmoid sinus diverticulum and/or dehiscence (SSDD) and healthy people. Material and Methods. A total of 199 unilateral persistent PT patients with SSDD and 302 control subjects underwent dual-phase contrast-enhanced CT (DP-CECT), to assess the grade of temporal bone pneumatization in each ear. Results. In the bilateral temporal bone of 302 controls, 16 ears were grade I, 53 were grade II, 141 were grade III, and 394 were grade IV. Among the affected ears of 199 PT cases, 1 ear was grade I, 18 were grade II, 53 were grade III, and 127 were grade IV. There was no significant difference in the pneumatization grade between the affected PT ear and either ear in the healthy subjects (p > 0.05). Conclusion. Although air cells within the temporal bone are an important factor in the occurrence of PT, its severity does not differ significantly from the pneumatization of healthy people.
