目的探讨乳突及岩尖气化与颈静脉球高位间的相关性。方法回顾性分析477例(954侧)颞骨CT片,统计乳突和岩尖的气化分型及各型颈静脉球高位的发生率,并对其作统计学分析。结果477例中颈静脉球高位的出现率右侧为40.67%(194例),左侧为21.38%(102例);女性出现率为35.37%,男性28.75%,差别均有统计学意义。岩尖气化I型与III型颈静脉球高位的发生率分别为31.25%及30.58%,乳突气化型与其它型颈静脉球高位的出现率分别为31.64%及29.02%,差别均不存在统计学意义。结论颈静脉球高位的发生率在两侧及性别间存在差异;颞骨气化与颈静脉球高位没有相关性。
Objective To explore the relationship between papillae and petroclival gasification and the jugular bulb. Methods 477 cases (954 lateral) CT images of the temporal bone were retrospectively analyzed. The gasification types of the papillae and petrous apex and the incidence of various types of jugular bulb hyperemesis were statistically analyzed. Results The incidence of jugular bulb in 477 cases was 40.67% (194 cases) on the right side and 21.38% (102 cases) on the left side. The incidence rate of females was 35.37% and that of males was 28.75%. The differences were statistically significant. The incidence rates of petroclival gasification type I and type III jugular bulb were 31.25% and 30.58%, respectively. The incidence rates of mastoid gasification and other types of high jugular bulb were 31.64% and 29.02%, respectively, with no difference There is statistical significance. Conclusions The incidence of jugular bulb hyperextension is different on both sides and between sexes. Gasification of the temporal bone has no correlation with the jugular bulb.
