The goal of rehabilitation after temporomandibular joint (TMJ) surgery is to achieve a normal range of motion. The aim of this study was to compare the impact of a comprehensive and early supervised rehabilitation programme with home-based exercise after TMJ condylar discopexy. Patients diagnosed with disc displacement without reduction were randomized to the study and control groups. After baseline assessments, the same surgical condylar discopexy procedure was applied to both groups. Following surgery, the study group patients underwent a supervised exercise programme conducted by a physiotherapist in the outpatient clinic...

Objectives: Mandibular condylar chondrocyte apoptosis is mainly responsible for the development and progression of temporomandibular joint osteoarthritis (TMJ-OA). Interleukin-1β (IL-1β) generally serves an agent that induces chondrocyte apoptosis. Hyperbaric oxygen (HBO) treatment increases proteoglycan synthesis in vivo. We explore the protective effect of HBO on IL-1β-induced mandibular condylar chondrocyte apoptosis in rats and the potential molecular mechanisms. Methods: Chondrocytes were isolated from the TMJ of 3-4-week old Sprague-Dawley rats...

OBJECTIVE: Temporomandibular joint (TMJ) diseases predominantly afflict women, suggesting a role of estrogen in the disease etiology. Previously, we determined that decreased occlusal loading (DOL) inhibited collagen type II (Col2) expression in the mandibular condylar cartilage (MCC) of female wild-type (WT) mice whereas no change was observed in males. This decrease in chondrogenesis was abolished by estrogen receptor beta (ERβ) deficiency in females. Therefore, the goal of this study was to examine the role of estradiol - ERβ signaling in mediating DOL effects in male mice to further decipher sex differences...

INTRODUCTION: TMJ arthrocentesis involves lavage of the upper joint space which forces the disc apart from the fossa and washes away the inflammatory components of the joint. To increase the joint space during arthrocentesis, the patient is usually asked to open the mouth and deviate it to the opposite side so as to distract the condyle from the glenoid fossa thereby increasing joint space. METHOD: The authors describe a simple and rapid technique of preparing a custom-made mouth prop to hold the mandible in eccentric position during arthrocentesis...

The purposes of this study were to evaluate the anti-nociceptive effect of oral and topical administration of (-)-α-bisabolol (BISA) in rodent models of formalin- or cinnamaldehyde-induced orofacial pain and to explore the inhibitory mechanisms involved. Orofacial pain was induced by injecting 1.5% formalin into the upper lip of mice (20 μL) or into the temporomandibular joint (TMJ) of rats (50 μL). In another experiment, orofacial pain was induced with cinnamaldehyde (13.2 μg/lip). Nociceptive behavior was proxied by time (s) spent rubbing the injected area and by the incidence of head flinching...

Temporomandibular Joint (TMJ) ankylosis is a situation in which the mandibular condyle is fused to the glenoid fossa by bone or fibrous tissue. The management of TMJ ankylosis has a complicated chore and it is challenging for the maxillofacial surgeon because of technical hitches and high rate of re-ankylosis. Interpositional gap arthroplasty is one of the modalities for its management. A range of inter-positional materials have been used to avert recurrence after gap arthroplasty in TMJ ankylosis. The aim of this series was to evaluate the effectiveness of the temporomyofacial flap in the treatment of TMJ ankylosis as an interpositional gap arthroplasty...

The purpose of this study was to develop and evaluate a novel method for real-time MRI of TMJ function at high temporal resolution and with two different contrasts. Real-time MRI was based on undersampled radial fast low angle shot (FLASH) acquisitions with iterative image reconstruction by regularized nonlinear inversion. Real-time MRI movies with T1 contrast were obtained with use of a radiofrequency-spoiled FLASH sequence, while movies with T2/T1 contrast employed a gradient-refocused FLASH version. TMJ function was characterized in 40 randomly selected volunteers by sequential 20s acquisitions of both the right and left joint during voluntary opening and closing of the mouth (in a medial, central and lateral oblique sagittal section perpendicular to the long axis of the condylar head)...

Maxillofacial prosthesis (MFP) can be defined as the art and science of esthetic and functional reconstruction of the facial bones, art because it uses hand-crafted and empirical rules, science because of its technical rigorism and its integration in medicine. MFP aims to multidisciplinary rehabilitate patients presenting with cutaneous and underlying structures defects, It also allows for functional speech and swallowing rehabilitation related to temporo-mandibular joint disorders. Whatever the origin, (traumatic, infectious ortumoral), surgical treatment of these TMJ disorders is usually not indicated in first-line...
