目的：运用 HRCT 对外耳道永存胡施克氏孔及其遗迹区薄弱进行活体形态学研究,为颞颌关节与外耳道相关疾病的影像诊断提供解剖学依据。方法2位放射科医师各自分析525例(5岁以上,共1050耳)双侧外耳道的 HRCT 薄层图像,判别有无永存胡施克氏孔及遗迹区薄弱。观察孔或薄弱区的形态、测量大小、内缘与鼓膜的距离。统计分析其发生率、性别差异及形态学测量数据。结果①共146耳有永存胡施克氏孔,发生率为13.91%,男40例,女77例,29例双耳发生。其横断位最大径平均为2.35 mm±1.16 mm(0.6~5.8 mm),矢状位最大径平均为2.09 mm±1.2 mm(0.5~6.2 mm),孔的内缘与鼓膜附着点的距离平均为1.61 mm±2.4 mm(0~10 mm)。②共233耳遗迹区薄弱,发生率为22.19%,男58例,女122例,53例双耳发生。其轴位最大径平均为2.43 mm±0.89 mm(0.8~5.4 mm),矢状位最大径平均为2.08 mm±0.73 mm(0.6~4.3 mm),与鼓膜附着点的距离平均为1.55 mm±1.2 mm(0~9.9 mm)。③137例(占90.73%)永存胡施克氏孔与221例(占94.43%)遗迹区薄弱发生在距鼓膜3 mm 以内区域。结论大样本活体 CT 解剖研究表明外耳道永存胡施克氏孔及其遗迹区薄弱并不少见,二者的大小、部位差异无统计学意义,均为外耳道内侧好发,女性多发。
目的：運用 HRCT 對外耳道永存鬍施剋氏孔及其遺跡區薄弱進行活體形態學研究,為顳頜關節與外耳道相關疾病的影像診斷提供解剖學依據。方法2位放射科醫師各自分析525例(5歲以上,共1050耳)雙側外耳道的 HRCT 薄層圖像,判彆有無永存鬍施剋氏孔及遺跡區薄弱。觀察孔或薄弱區的形態、測量大小、內緣與鼓膜的距離。統計分析其髮生率、性彆差異及形態學測量數據。結果①共146耳有永存鬍施剋氏孔,髮生率為13.91%,男40例,女77例,29例雙耳髮生。其橫斷位最大徑平均為2.35 mm±1.16 mm(0.6~5.8 mm),矢狀位最大徑平均為2.09 mm±1.2 mm(0.5~6.2 mm),孔的內緣與鼓膜附著點的距離平均為1.61 mm±2.4 mm(0~10 mm)。②共233耳遺跡區薄弱,髮生率為22.19%,男58例,女122例,53例雙耳髮生。其軸位最大徑平均為2.43 mm±0.89 mm(0.8~5.4 mm),矢狀位最大徑平均為2.08 mm±0.73 mm(0.6~4.3 mm),與鼓膜附著點的距離平均為1.55 mm±1.2 mm(0~9.9 mm)。③137例(佔90.73%)永存鬍施剋氏孔與221例(佔94.43%)遺跡區薄弱髮生在距鼓膜3 mm 以內區域。結論大樣本活體 CT 解剖研究錶明外耳道永存鬍施剋氏孔及其遺跡區薄弱併不少見,二者的大小、部位差異無統計學意義,均為外耳道內側好髮,女性多髮。

Objective To study the morphology of the persistent foramen of Huschke (PHF)and the weakness of the remains of foramen of Huschke (WRHF)in the external auditory canal (EAC)by high resolution computer tomography (HRCT)in vivo. Methods The thin HRCT images of 525 cases elder than 5 years were retrospectively reviewed by two radiologists,to detect the PHF or WRHF,and to depict the precise location,size and the distance to the tympanic membrane.The incidence,sex differences, and morphologic data of PHF and WRHF were statistical analyzed.Results ①PHFs were found in 146 EACs of 40 males and 77 fe-males with the prevalence of 13.91%,and were found on both sides in 29 cases.Mean maximum axial diameter was 2.35 mm± 1.1 6 mm (0.6-5.8 mm)and sagittal diameter was 2.09 mm±1.2 mm (0.5-6.2 mm).Mean distance between the inner edge of PFH and the sulcus tympanicus was 1.61 mm±2.4 mm (0-10 mm).②WRHFs were found in 233 EACs of 58 males and 122 fe-males with the prevalence of 22.1 9%,and were found on both sides in 53 cases.Mean maximum axial diameter was 2.43 mm± 0.89 mm (0.8-5.4 mm)and sagittal diameter was 2.08 mm±0.73 mm (0.6-4.3 mm).Mean distance between the inner edge of WRPFH and the sulcus tympanicus was 1.55 mm±1.2 mm (0 - 9.9 mm).③The distance to the sulcus tympanicus was within 3 mm in 137 cases (90.73%)of PFHs and 221 cases (94.43%)of WRFHs.Conclusion Both PHF and WRFH are common by the CT morphological study in vivo.The medial part of EAC is predominant and female is predominant.The incidence and the location of PHF and WRFH are no significant difference.
