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.

Study Design: Free fibula flaps are nowadays the gold standard for the surgical reconstruction on large mandibular defects. Malocclusion is an important complication of this type of reconstruction and many of these patients end up requiring subsequent orthognathic corrective surgery. This is a descriptive retrospective case series study. Objective: To describe the demographic data, operative techniques, corrective methods and postoperative results in the management of malocclusion following mandibular reconstruction with free fibula flap. Methods: This case series study included patients who underwent free fibula flap mandibular reconstructions and who that subsequently developed malocclusion requiring orthognathic corrective surgery, from June 2010 to December 2019. Panoramic X-rays, cephalometries and/or 3-D facial reconstruction CT scans were used for surgical planning to create surgical cutting guides, templates and occlusal splints in all the patients that underwent corrective orthognathic surgery. Results: There were 46 patients who underwent a free fibula flap mandibular and maxillary reconstruction at San Jose Hospital between June 2010 and December 2019 of these, 5 patients (10.9%) developed postoperative malocclusion. One case from another institution was added to this study for a total of 6 patients with malocclusion following mandibular reconstruction surgery with a fibula free flap. During the orthognathic surgery, vertical osteotomies were performed in 3 patients and bilateral sagittal split osteotomies were necessary in 2 patients and L-shape in 1 patient. Osteogenic distraction was performed in 3 patients as part of their orthognathic treatment. The fixation methods were based in miniplates for 3 of the patients and lag screws for the remaining 3 patients. With this approach, all patients had an adequate occlusion correction with a 100% consolidation at their 6-month follow up. Conclusion: Malocclusion is a significant complication following mandibular reconstruction surgery that must be identified and managed. In severe cases, it requires corrective orthognathic surgery in severe cases. We have developed a protocol to avoid pitfalls during the primary reconstruction and in case an orthognathic surgery is required for malocclusion correction, preoperative planning with cutting guides and occlusal splints should be assessed, to guarantee favorable results through a reproducible technique.

Introduction Maxillary advancementis applied extensively for malocclusion class III correction.This procedure is done using one of the two methods, Conventional or High. Maxilla moves in both vertical and horizontal and only in the horizontal directions in Conventional and High method respectively, so expecting a difference in facialsoft tissue changes. In present study is a case series that describes this issue. Materials and Methods: The cases included 30 patients with class III malocclusion due to maxillary deficiency, whom underwent Le Fort I osteotomy for maxillary advancement in Shahid Beheshti Hospital in Babol, Iran during 1995 to 1995. According to surgical technique, the cases were placed in group 1 (Conventional) or group 2 (High). Maxillary advancement and changes in hard and soft tissue of the middle and lower facial regions where measured through tracing on the lateral cephalometry. Intra-group and inter-group statistical comparisons were done using SPSS20 software at significance level as 0.05. Result: The pre-surgical mean size of SNA, SNB, nasolabial and mentolabial angles was similar in two groups. In all patients, after surgery, SNA angle size was increased and SNB، nasolabial and Mentolabial angles size were decreased. The mean value of these change was similar in two groups. In group 2, the displacement of point A ‘(mean difference: 1.30 mm) and Labrale Superius (mean difference: 1.40 mm) were significantly more than group 1. The amount of displacement of SN (mean difference: 1.30 mm), Labrale Inferius (mean difference: 0.88 mm) and Pogonion (mean difference: 0.23 mm) points in group 2 was higher than that of group 1, but this difference was not statistically significant. Conclusion: It is needed strong evidence for decision about selecting High or Conventional approach maxillary advancement in terms of facial aesthetic aspects. So, further studies with larger sample sizes and cohort or quasi-experimental design is suggested
