目的通过对上颌骨后部的应用解剖学观察,为Le Fort I型截骨术的手术切口设计提供形态学基础。方法选择40例干性头颅标本,观测与Le Fort I型截骨术有关的上颌骨后部解剖结构,并比较其性别和侧别差异。结果翼上颌联合为骨性融合型占22.5%,多见于右侧。翼上颌联合和上颌骨后部高度分别为(13.7±3.1)mm和(18.7±4.2)mm;上颌结节-第二磨牙、-第三磨牙切口和翼上颌联合切口深度分别为(16.1±2.4)mm、(19.7±3.3)mm和(11.8±1.9)mm;腭中缝与3种切口夹角分别为69.3°±8.0°、89.3°±9.6°和111.1°±9.4°;27.5%的上颌结节-第二磨牙切口经过腭大孔;鼻腔外侧壁切口长度为(33.1±3.3)mm,翼腭管与硬腭夹角为64.1°±7.9°。男性翼上颌联合切口深度和鼻腔外侧壁切口长度大于女性。结论熟悉上颌骨后部的解剖有助于LeFort I型截骨术手术切口的设计。
Objective To observe the anatomy of the posterior maxilla and provide a morphological basis for the surgical incision design of Le Fort I osteotomy. Methods Forty cases of dry skull specimens were selected to observe the posterior maxillary anatomy related to Le Fort I osteotomy. The gender and lateral differences were compared. The results of the maxillary wing fusion accounted for 22.5% of bone fusion, more common in the right. The maxillary and maxillary posterior height were (13.7 ± 3.1) mm and (18.7 ± 4.2) mm, respectively. The maxillary nodule-second molar-third molar incision and maxillary wing incision depth were (16.1 ± 2.4) mm ) mm, (19.7 ± 3.3) mm and (11.8 ± 1.9) mm, respectively. The angle between the incision and the three incisions was 69.3 ° ± 8.0 °, 89.3 ° ± 9.6 ° and 111.1 ° ± 9.4 °, respectively. 27.5% Section - second molars incision through the large palatal hole; nasal lateral wall incision length (33.1 ± 3.3) mm, the angle between the palatal palate and hard palate 64.1 ° ± 7.9 °. Male wing maxillary incision depth and nasal lateral wall incision length greater than the female. Conclusions Familiarity with the anatomy of the posterior maxilla contributes to the design of the surgical incision for LeFort type I osteotomy.
