Abstract Background We investigated the efficacy of a maxillary Jackson-Pratt (J-P) suction drain for preventing maxillary sinus hematoma and facial swelling after maxillary Le Fort I osteotomy (LF1). Methods We retrospectively evaluated 66 patients who underwent LF1 at a single institution. Of these, 41 had a J-P suction tube inserted in the mandible and maxilla (maxillary insertion), and 25 had a J-P drain inserted in the mandible only (no maxillary insertion). Facial CT was obtained before and 4 days after surgery. We compared mean midfacial swelling and maxillary sinus haziness by t test and examined correlations between bleeding amount and body mass index (BMI). Results For the maxillary-insertion group, the ratio of total maxillary sinus volume to haziness (57.5 ± 24.2%) was significantly lower than in the group without maxillary drain insertion (65.5% ± 20.3; P = .043). This latter group, however, did not have a significantly greater midfacial soft tissue volume (7575 mm3) than the maxillary-insertion group (7250 mm3; P = .728). BMI did not correlate significantly with bleeding amount or facial swelling. Conclusions Suction drainage in the maxilla reduced maxillary sinus haziness after orthognathic surgery but did not significantly reduce midfacial swelling.

When occlusal alterations are not accompanied by paranasal deficiencies, mobilization of the maxilla via Le Fort I osteotomy should be made with a different design. In this preliminary report, a W-shaped osteotomy that doesn’t change the position of the maxillary bone surrounding the pyriform aperture was presented for the first time. Advantages and indications of this new procedure are discussed.

Abstract The design and fabrication of three-dimensional (3D) -printed patient-specific implants (PSIs) for orthognathic surgery are customarily outsourced to commercial companies. We propose a protocol of designing PSIs and surgical guides by orthognathic surgeons-in-charge instead for wafer-less Le Fort I osteotomy. The aim of this prospective study was to evaluate the accuracy and post-operative complications of PSIs that are designed in-house for Le Fort I osteotomy. The post-operative cone beam computer tomography (CBCT) model of the maxilla was superimposed to the virtual surgical planning to compare the discrepancies of pre-determined landmarks, lines and principal axes between the two models. Twenty-five patients (12 males, 13 females) were included. The median linear deviations of the post-operative maxilla of the x, y and z axes were 0.74 mm, 0.75 mm and 0.72 mm, respectively. The deviations in the principal axes for pitch, yaw and roll were 1.40°, 0.90° and 0.60°, respectively. There were no post-operative complications related to the PSIs in the follow-up period. The 3D-printed PSIs designed in-house for wafer-less Le Fort I osteotomy are accurate and safe. Its clinical outcomes and accuracy are comparable to commercial PSIs for orthognathic surgery.

Introduction: Nasotracheal intubation (NTI) is preferred for general anesthesia in maxillofacial surgery. However, NTI is often traumatic or even unsuccessful, particularly in patients with a narrow nasal pathway. In this case report, we describe a less traumatic NTI approach using maxillary downfracture of Le Fort I osteotomy. Case presentation: A 19-year-old woman was admitted with a skeletal Class III malocclusion and scheduled to undergo bimaxillary orthognathic surgery. A preoperative evaluation revealed no other medical history and abnormal laboratory findings. Preoperative computed tomography showed nasal septal deviation, concha bullosa, and turbinate hypertrophy. A nasal Ring-Adair-Elwyn endotracheal tube and a tube exchanger could not be inserted via NTI because of her narrow nasal cavity. An oral intubation was performed temporarily and surgery was started. After a maxillary downfracture was performed, which made the nasal cavity wider than before, NTI was successfully conducted without difficulty. The patient was ventilated without any problems, and the operation was continued. Postoperatively, the patient had no further complications and her vital parameters were all stable. Conclusions: This case report suggests that NTI after maxillary downfracture of Le Fort I osteotomy can be a good alternative that can be successfully performed with less trauma in patients undergoing orthognathic surgery who are preoperatively evaluated as having a narrow nasal cavity.

Nasal Changes

Orthognathic surgery involves the correction of severe dentofacial deformities through a combination of orthodontics, surgery and, occasionally, restorative dentistry. This procedure, when involving surgical movement of the maxilla, can lead to changes in the overlying nasal morphology. In this paper, the standard nasal assessment that is undertaken prior to a Le Fort I osteotomy is outlined along with the reported nasal changes seen following this procedure. In addition, the various risk factors associated with adverse nasal changes are considered, as are the management techniques adopted by clinicians to minimize these changes CPD/Clinical Relevance: Clinicians should be aware of the adverse nasal changes associated with the Le Fort I osteotomy.
