Abstract

Purpose: To investigate the anatomical variations and measure the distances between surgically relevant structures in the maxilla associated with Le Fort I osteotomy in patients with maxillary canting using cone beam computed tomography (CBCT).

Methods: CBCT scans of 63 patients (21 males and 42 females) with maxillary canting who were indicated for orthognathic surgical planning were retrospectively investigated and analyzed. The distances of the relevant anatomical structures, including the descending palatine artery, pterygomaxillary junction, infraorbital foramen, and nasolacrimal duct opening, were measured with the key anatomical landmarks to evaluate their variations. The independent correlations of measurements with magnitude of canting were examined, considering a 5% significance level.

Results: Among the 63 patients, the mean vertical difference of maxillary canting was 3.26 ± 0.98 mm and 3.62° ± 1.09°. The descending palatine artery differed significantly in distance between the longer and shorter sides (P < 0.001). Similar significant differences were found in the pterygomaxillary junction distance (P < 0.001), pterygomaxillary junction height (P < 0.001), and infraorbital foramen distance (P = 0.009). Every 1 mm of maxillary canting increases the pterygomaxillary junction distance by 0.1721 mm, pterygomaxillary junction height by 0.2773 mm, infraorbital foramen by 0.3301 mm, and nasolacrimal duct in 0.2255 mm.

Conclusion: Maxillary canting significantly affects the morphometrics of pterygomaxillary junction distance and height, infraorbital foramen, and nasolacrimal duct on the longer and shorter sides. Therefore, these surgical anatomies should be of concern when performing Le Fort I osteotomy in patients with maxillary canting.

Clinical trial number: Not applicable.

与 Le Fort I 截骨术相关的上颌骨倾斜和解剖变异：利用锥形束计算机断层扫描进行的形态计量学研究。

目的：利用锥形束计算机断层扫描（CBCT）研究上颌倾斜患者在Le Fort I型截骨术时的解剖变化，并测量上颌手术相关结构之间的距离。方法：对63例上颌倾斜患者（男21例，女42例）的CBCT扫描结果进行回顾性分析。用关键解剖标志测量相关解剖结构的距离，包括腭降动脉、翼颌交界处、眶下孔和鼻泪管开口，以评估其变化。考虑到5%的显著性水平，检测了测量值与倾斜幅度的独立相关性。结果：63例患者上颌倾斜的平均垂直度差为3.26±0.98 mm, 3.62°±1.09°。结论：上颌倾斜对长、短侧翼颌交界处的距离、高度、眶下孔、鼻泪管的形态计量学有显著影响。因此，在上颌倾斜患者进行Le Fort I型截骨术时，应注意这些手术解剖。临床试验号：不适用。

期刊介绍： Oral & Maxillofacial Surgery founded as Mund-, Kiefer- und Gesichtschirurgie is a peer-reviewed online journal. It is designed for clinicians as well as researchers.The quarterly journal offers comprehensive coverage of new techniques, important developments and innovative ideas in oral and maxillofacial surgery and interdisciplinary aspects of cranial, facial and oral diseases and their management. The journal publishes papers of the highest scientific merit and widest possible scope on work in oral and maxillofacial surgery as well as supporting specialties. Practice-oriented articles help improve the methods used in oral and maxillofacial surgery.Every aspect of oral and maxillofacial surgery is fully covered through a range of invited review articles, clinical and research articles, technical notes, abstracts, and case reports. Specific topics are: aesthetic facial surgery, clinical pathology, computer-assisted surgery, congenital and craniofacial deformities, dentoalveolar surgery, head and neck oncology, implant dentistry, oral medicine, orthognathic surgery, reconstructive surgery, skull base surgery, TMJ and trauma.Time-limited reviewing and electronic processing allow to publish articles as fast as possible. Accepted articles are rapidly accessible online.Clinical studies submitted for publication have to include a declaration that they have been approved by an ethical committee according to the World Medical Association Declaration of Helsinki 1964 (last amendment during the 52nd World Medical Association General Assembly, Edinburgh, Scotland, October 2000). Experimental animal studies have to be carried out according to the principles of laboratory animal care (NIH publication No 86-23, revised 1985).
