Introduction: Cleft patients often need orthognathic surgery to correct maxillary hypoplasia and rhinoplasty to correct nasal deformity. Rhinoplasty can be performed as a staged procedure after orthognathic surgery or simultaneously with maxillary osteotomy.
Aim: The authors evaluated need for and complications of staged and simultaneous rhinoplasties in patients with different cleft types undergoing maxillary osteotomy.
Patients And Methods: This retrospective study examined 99 (54 females) consecutive nonsyndromic patients with cleft lip/palate [23 bilateral cleft lip and palate (BCLP), 51 unilateral cleft lip and palate (UCLP), and 25 cleft palate (CP)] with a mean age of 17.8 (range: 11.5-45.3) years who had undergone Le Fort I maxillary advancement or bimaxillary osteotomy at the Cleft Palate and Craniofacial Center, Helsinki University Hospital, Finland, between 2002 and 2016. Medical charts were accessed through the hospital's archives and database.
Results: Of patients who underwent maxillary osteotomy, 45% (45/99) needed rhinoplasty (14 BCLP, 27 UCLP, and 4 CP). A significant difference ( P <0.01) existed in the need for rhinoplasty between different cleft types, those with BCLP and UCLP needing the most operations (60% and 53%). In 20 patients (20%), rhinoplasty was performed simultaneously with maxillary osteotomy, and in 25 patients (25%) in a second operation after osteotomy. The overall complication rate was 14%. No difference existed in complication rate in patients with or without simultaneous rhinoplasty.
Conclusions: Of cleft patients who underwent maxillary osteotomy, 45% needed rhinoplasty. Patients with BCLP and UCLP needed rhinoplasty most often. Staged and simultaneous procedures were almost equally common with similar complication rates.

Background/purpose: Studies have indicated that 50%-55% of the population have malocclusion, and approximately 5%-10% require orthognathic surgery to correct this condition. Optimal placement of plates and screws significantly affects the success rate of the surgery and postoperative stability. This study evaluates the cortical thickness of the maxillary bone in the nasomaxillary and zygomaticomaxillary buttress regions in Taiwanese patients based on cone-beam computed tomography (CBCT) images.

Background: The study aimed to investigate the effect of customized lateral nasal wall osteotomy (LNO) on the lateral nasal wall (LNW) and pterygomaxillary junction (PMJ) separation during Le Fort I. We hypothesized that customized LNO on the LNW affect the PMJ separation type.
Material And Methods: This prospective, controlled, randomized study included forty-three patients were randomly assigned to either the conventional or customized (study) osteotomy groups.

Introduction: The cant of the occlusal plane in the frontal plane reflects facial asymmetry. Its treatment requires close collaboration between the orthodontist and the maxillofacial surgeon. In case of mild cant, treatment consists in coordination of dental arches followed by mandibular osteotomy.

Pterygomaxillary separation (PMS) is an important step in Le Fort I osteotomy procedure, without which complete mobilization of the maxilla cannot be achieved. The aim of this study was to evaluate PMS patterns and their relationship with the anatomic measurements in Le Fort I osteotomy. In this prospective observational study cone beam computed tomography (CBCT) was used to measure the anatomic variables of the pterygomaxillary junction (PMJ) region including thickness, width, the distance between the most concave point at the lateral surface of PMJ and the greater palatine foramen (C-GPF), and the angle preoperatively, and the separation patterns postoperatively divided into the clean-cut type, maxillary sinus type, and the pterygoid fracture type.

Background: To analyze the biomechanical and functional characteristics of different maxillary fixation techniques after Le Fort I osteotomy and occlusal plane rotation, using the finite element method to simulate the mechanical behavior of three different osteosynthesis approaches.
Material And Methods: This is a virtual experimental study carried out using finite element analysis to compare three different osteosynthesis techniques after Le Fort I osteotomy and rotation of the maxillary occlusal plane. Three configurations were tested: four-point fixation with "L" plates (C1), two-point fixation with "L" plates (C2), and two-point fixation with pre-modeled Lindorf plates (C3).
