Pterygoid process fractures (PPFs) are classically associated with Lefort fractures but can also be encountered in association with other facial fractures such as mandibular fractures. The aim of this study was to estimate the frequency of PPFs associated with mandibular fractures and identify factors associated with PPF.

We conducted a retrospective cross-sectional study using computed tomography scanning of patients having a mandibular fracture between November 2018 and April 2020. PPFs were classified using the classification by An etal. Volume, length, and width of both lateral pterygoid muscles have been evaluated by using an image processing software. Study population has been divided into 2 groups fracture of pterygoid process or the absence of PPF. To evaluate the implication of lateral pterygoid muscle in the pathophysiology of PPF, we compared lateral pterygoid muscle volume, its maximal length, and width between both groups. Patients with bilateral fractures were excluded from this analysis.

About 304 patients with at least 1 mandibular fracture have been included in this study. About 18 patients presenting an association of mandibular fracture and PPF were finally selected. About 83.33% of the patients were concerned by a fracture of the posterior part of the mandible. The PPF was classified as type IIA by the classification of An etal for 94.4% of patients. The lateral pterygoid muscle volumes were significantly larger on the side of the PPF (P=.02). However, there were no significant differences in the maximum length (P=.49) and width (P=.1) of lateral pterygoid muscle.

Our study showed an association between mandibular fractures (mainly ipsilateral posterior) and isolated PPF through a lateral pterygoid muscle volume increase.

To characterize adequate study of chronic neuropathic orofacial pain induced by a mental nerve injury in a mouse model, we propose a behavioral assessment of its dimensions sensory, affective, and cognitive.

Trigeminal injury was induced by a chronic mental nerve constriction (MnC). Behavioral tests were conducted to assess the different dimensions of pain and to evaluate the general well-being of mice.

Rodents who went through MnC showed signs of mechanical hyperalgesia and increased escape/avoidance behavior. They showed no alterations in general well-being behaviors, yet the injury was sufficient to induce impairment in the ability to adapt to the environmental requirements.

MnC injury is an efficient model for the study of orofacial pain in mice, capable of inducing impairment in the different dimensions of pain. Intensity and temporality of its effects make our model less aggressive, yet effective to generate cognitive impairment. This work provides a solid foundation for the study of the neural circuits involved in the processing of neuropathic orofacial pain.

Adult temporomandibular joint ankylosis (TMJA) lacks a uniform management protocol. The purpose of the study was to evaluate the outcome of stock total joint replacement (TJR) along with fat grafting around the joint in adult TMJA patients. Specific aim was to find out whether TJR can be a definitive management for adult TMJA.

The investigators implemented a prospective study on adult TMJA patients treated with ostearthrectomy of ankylosis and stock temporomandibular joint (TMJ) TJR with fat grafting. Concomitant orthognathic correction of facial asymmetry was performed in some unilateral cases. Follow-up was carried out at regular intervals for assessing primary outcome variable of maximal incisal opening (MIO) and reankylosis. see more Secondary outcome variable included demographic data, etiology, duration of ankylosis (DOA), correlation between DOA and preoperative and postoperative MIO, occlusion and complications of hemorrhage, facial nerve paresis, periprosthetic joint infection, dislocation, and implant faints provides adequate mouth opening without any sign and symptoms of reankylosis. Stock TMJ TJR with fat grafting can be considered as a definitive treatment modality in adult TMJA with minimum comorbidity.

Blood transfusion is usually a common clinical practice in flap transfer surgery because of its invasive hemorrhagic nature. Although intraoperative restrictive transfusion policy was suggested in vascularized fibular flap reconstruction, its clinical evidence was still insufficient. Therefore, our study aimed to investigate the influence of intraoperative blood transfusion on length of stay (LOS) after vascularized fibular flap reconstruction.

Patients who underwent vascularized fibular flap reconstruction of mandibulofacial defects between 2012 and 2018 were reviewed. Univariate and multivariate analyses were performed to identify factors that influenced LOS. The identified factors and other perioperative factors that may influence transfusion decision were included in propensity score matching to explore the independent impact of intraoperative blood transfusion on LOS.

About 375 patients were included, and the median LOS was 14.00 (12.00, 19.00) days in our study. Multivariate analysis suggested thausion is independently associated with prolonged LOS in patients without preoperative anemia, radiotherapy history, or intraoperative massive hemorrhage who undergo vascularized fibular flap reconstruction. Efforts should be made to avoid unnecessary intraoperative blood transfusion, and our results support consideration of a restrictive transfusion policy in these patients.
