This study aimed to elucidate whether the stability of an unsintered hydroxyapatite particles/poly--lactide (uHA/PLLA) system is comparable with that of titanium, according to different load-bearing areas of the mandible. The study included patients who underwent open reduction and internal fixation of the mandibular body, angle, or subcondylar fracture. The stability of uHA/PLLA systems was compared between the immediate and 6-month postoperative time points using three-dimensional cone-beam CT image analysis. The positional changes of each landmark were measured in three-dimensional (3D) coordinate systems using simulation software. Among 36 patients, there were more displacements of the landmarks between the immediate and 6-month postoperative time points after subcondylar fracture reduction than after body or angle fracture reductions. Strong upward displacements of the landmarks after subcondylar fracture reduction were found in the lateral pole [mean (SD) = 1.75 (3.16), p-value = 0.003] and medial pole [mean (SD) = 1.64 (2.50), p-value = 0.024], but not in the center. Subgroup analyses revealed similar unstable results in males on the condylar landmarks after subcondylar fracture reduction. There were tendencies for lateral displacement of the coronoid process in the body fracture group [mean (SD) = 0.8 (0.83)] and angle fracture group [mean (SD) = 0.75 (0.58)] postoperatively (p-value = 0.01). This study concluded that bioresorbable osteosynthesis can be recommended for body or angle fractures, while the indication for subcondylar fractures is less clear.

Purpose: Preoperative virtual planning and osteosynthesis with patient-specific implants (PSIs) have become a quotidian approach to many maxillofacial elective surgery setups. When a process is well-organized, a similar approach can be harnessed to serve the needs of exact primary reconstructions, especially in midfacial trauma cases. PSI osteosynthesis of the mandible is, however, more challenging because a mirror technique of the facial sides is often unreliable due to inherent lack of symmetry, and movement of the mandible increases the risk of loosening of the osteosynthesis.

Background: The choice of treatment for subcondylar fractures in children and adolescents remains a controversial issue. The aim of this study was to evaluate the association between the treatment modality of subcondylar fractures and functional outcomes at the six-month follow-up.
Methods: This retrospective study examined a cohort of children and adolescents with unilateral or bilateral subcondylar fractures treated at a level 1 trauma center over a five-year period.

Introduction: Mandibular condylar fractures are among the most common facial fractures and its incidence has been rising since the past few decades. Although various approaches for management of mandibular condylar fractures have been described in literature there is a gap in the published literature when it comes to comparison of these approaches. There have only been a handful of studies which have compared use of Retromandibular Transparotid against Retromandibular anteroparotid approach in management of mandibular condylar fractures with conflicting results.

Fractures of the condylar region of the mandible, although fairly common, also generate the most debate regarding management-both closed and open treatment options have been recommended and shown to yield good results. We present our experience with a minimal access retromandibular approach to fractures of the vertical mandible. This is a retrospective study of all patients who underwent open reduction and internal fixation for fractures of the vertical mandible (condyle, subcondylar region, ramus) using a retromandibular approach at a tertiary care hospital in a metropolitan city in India between January 2022 and July 2023.

Background: The aim of the study was to evaluate the etiology, incidence, demographics, and characteristics of maxillofacial fractures treated at a university hospital over a seven-year period.
Methods: We performed a retrospective analysis of 1,757 patients with maxillofacial fractures who were referred to our department between May 2012 and March 2019. The patients' demographic and clinical characteristics were noted, as well as the fracture type, location, and etiology.
