The objective of this study is to determine the incidence and degree of anterior clinoid process pneumatization, in addition highlighting to their clinical significance. Multidetector-row CT scans of the skull base were reviewed in 648 subjects between 2007 and 2008. The presence of pneumatized anterior clinoid process and its degree were studied and documented. These data were statistically analyzed. Pneumatization of the ACP was found in 62 of 648 patients (9.6%) including 32 (51.6%) men and 30 (48.4%) women. The age of these patients ranged from 21 to 82 years (mean, 41 +/- 15.7 years). Pneumatization of the ACP occurred only on the left side in 14 cases (22.6%), only on the right side in 11 cases (17.7%), and bilaterally in 37 patients (59.7%). ACP pneumatization Type I, in which less than 50% of the ACP is pneumatized, was found in 47 of 124 sides (38%), Type II, in which more than 50% but not totally pneumatized ACP, was found in 28 of 124 sides (22.6%), and Type III, in which the ACP is totally pneumatized, was found in 22 of 124 sides (17.7%). The incidence of Type I in the general population was 6.6%, Type II was 3.5%, and Type III was 2.5%. Radiologically recognizing the degree of ACP pneumatization is important in decreasing the incidence of surgical complications during anterior clinoidectomy. Proper intraoperative management can be undertaken with special attention to the new classification.
本研究旨在确定前床突气化的发生率和程度，并强调其临床意义。我们回顾了 2007 年至 2008 年间 648 例头颅底多排 CT 扫描。研究并记录了前床突气化的存在及其程度。对这些数据进行了统计学分析。在 648 例患者中，62 例（9.6%）发现前床突气化，其中 32 例（51.6%）为男性，30 例（48.4%）为女性。这些患者的年龄为 21-82 岁（平均 41+/-15.7 岁）。前床突单侧气化（14 例，22.6%）、双侧气化（37 例，59.7%）和右侧气化（11 例，17.7%）。ACP Ⅰ型（前床突不到 50%气化）在 124 侧中占 47 侧（38%），Ⅱ型（前床突超过 50%但未完全气化）在 124 侧中占 28 侧（22.6%），Ⅲ型（前床突完全气化）在 124 侧中占 22 侧（17.7%）。ACP Ⅰ型在前人群中的发生率为 6.6%，Ⅱ型为 3.5%，Ⅲ型为 2.5%。在进行前床突切除术时，放射学上识别前床突气化程度对降低手术并发症的发生率非常重要。通过特殊关注新的分类，可以进行适当的术中管理。
