To analyse the degree of pneumatisation of the temporal bone when there is an association between dehiscence of the superior semicircular canal and dehiscence of the tegmen tympani.
We analysed a retrospective CT study of 124 selected cases. A single inclusion criterion was applied: the presence of a dehiscence of the tegmen tympani. On the other hand, the degree of temporal pneumatisation was assessed by axial and coronal planes, and has been divided into the following grades O, I, II and III, according to the status and relationship of the mastoid, the bony labyrinth, the petrous segment of the carotid canal and sigmoid sinus.
Of the 124 cases studied, 35 (28.2%) presented both dehiscences. In 26 of the 35 (47.3%), grade II pneumatisation, 4 (14,8%), grade I, and 5 (11,9%) grade III was observed, with a statistically significant relationship (p < 0.001). On the other hand, we did not find a significant relationship when relating both dehiscences in any age or sex group. However, when relating the degree of pneumatisation to sex, among those with grade III pneumatisation, the proportion of men (52.4%) was significantly higher than that of women (47.6%) (p = 0.017).
We have detected a statistically significant relationship between the coexistence of grade II pneumatisation and the presence of both dehiscences in the temporal bone.
分析上半规管裂和鼓室盖裂之间存在关联时颞骨气化的程度。
我们对 124 例经选择的病例进行了回顾性 CT 研究。应用单一纳入标准：存在鼓室盖裂。另一方面，通过轴位和冠状位评估颞骨气化程度，并根据乳突、骨迷路、颈内动脉岩骨段和乙状窦的状况和关系分为 O、I、II 和 III 级。
在研究的 124 例病例中，35 例（28.2%）同时存在两种裂。在 35 例中，26 例（47.3%）为 II 级气化，4 例（14.8%）为 I 级，5 例（11.9%）为 III 级，存在统计学显著关系（p < 0.001）。另一方面，我们在任何年龄或性别组中都没有发现这两种裂之间存在显著关系。然而，当将气化程度与性别相关联时，在 III 级气化的患者中，男性（52.4%）的比例明显高于女性（47.6%）（p = 0.017）。
我们发现 II 级气化程度与颞骨中同时存在两种裂之间存在统计学显著关系。
