G Bai, C Yang, Y Qiu, M Chen
Open surgery and arthroscopy for the treatment of synovial chondromatosis (SC) of the temporomandibular joint (TMJ) have their advantages and disadvantages. The aim of this study was to report the application and results of the combined use of these two methods in the treatment of SC and the indications for use. A total of 36 patients with magnetic resonance imaging (MRI) confirmation of SC, treated from 2010 to 2015, were included. Patients with tumours in the upper articular cavity and with the extended margin of the medial groove still in-between the medial crest of the condyle and infratemporal space on coronal MRI were selected to undergo open surgery with the assistance of arthroscopy to clear the loose bodies and affected synovium...

INTRODUCTION: The temporomandibular joint is highly adaptive and masticatory apparatus disorders (MAD) can occur when its ability to adapt is overwhelmed. Occlusal etiologies were long pinpointed as the sole culprits. However, a consensus now exists which minimizes their involvement. It is recognized that the etiology of MAD is multifactorial, combining occlusal problems, parafunctions, postural anomalies, orofacial dyspraxia and stress. MATERIALS AND METHODS: In this article, the authors review the role of physiotherapy in managing these pathologies...

PURPOSE: To explore the potential use of concentrated growth factor (CGF) in the treatment of temporomandibular joint osteoarthritis (TMJ-OA). MATERIALS AND METHODS: Surgical defects were created bilaterally on the condylar cartilage and bone to induce TMJ-OA in goats. CGF was applied to the right joints (CGF group) and physiologic saline was applied to the left joints (unrepaired group). There was a 1-month period of observation after the operation. These joint specimens were evaluated and compared based on gross appearance and histopathologic observations with hematoxylin and eosin (HE)...

Tissue regeneration using stem cell-based transplantation faces many hurdles. Alternatively, therapeutically exploiting endogenous stem cells to regenerate injured or diseased tissue may circumvent these challenges. Here we show resident fibrocartilage stem cells (FCSCs) can be used to regenerate and repair cartilage. We identify FCSCs residing within the superficial zone niche in the temporomandibular joint (TMJ) condyle. A single FCSC spontaneously generates a cartilage anlage, remodels into bone and organizes a haematopoietic microenvironment...

Oral appliance therapy (OAT) has become an increasingly popular nonsurgical option for the treatment of obstructive sleep disorders. Recent research supports its efficacy and high levels of compliance for patients with obstructive sleep disorders. Common side effects of OAT include temporomandibular joint-related symptoms, bite changes, and tooth movement. These side effects can be minimized by the use of exercises. The American Academy of Dental Sleep Medicine and the American Academy of Sleep Medicine have released joint clinical practice guidelines for the treatment of obstructive sleep apnea and snoring with OAT...

BACKGROUND: Internal derangement of the temporomandibular joint (TMJ) is one of the most common forms of temporomandibular disorders. The minimally invasive treatments such as arthrocentesis as well as arthroscopic lysis and lavage are often used as a first-line surgical treatment or in conjunction with nonsurgical modalities with low morbidity and high efficacy. Sodium hyaluronate (SH) has been proposed as an alternative therapeutic agent with similar therapeutic effects. OBJECTIVE: A prospective study was carried out for evaluation of efficacy of TMJ arthrocentesis with and without injection of SH in management of internal derangements...

Temporomandibular disorders (TMDs) are among the most common maxillofacial complaints and a major cause of orofacial pain. Although current treatments provide short- and long-term relief, alternative tissue engineering solutions are in great demand. Particularly, the development of strategies, providing long-term resolution of TMD to help patients regain normal function, is a high priority. An absolute prerequisite of tissue engineering is to understand normal structure and function. The current knowledge of anatomical, mechanical, and biochemical characteristics of the temporomandibular joint (TMJ) and associated tissues will be discussed, followed by a brief description of current TMD treatments...

The temporomandibular joint (TMJ) dislocation can be categorised into three groups: acute, habitual or recurrent and long-standing. The long-standing or protracted lower jaw dislocation refers to a condition that persists for more than one month without reduction. There are a great variety of methods for its treatment, from the manual or non-surgical, to surgical ones like the indirect approach (conservative surgical approach) and direct approach (open joint). Additional procedures in unsuccessful cases may include extra-articular orthognathic techniques to correct a malocclusion until joint replacement...

Surgery of the temporomandibular joint (TMJ) is increasingly recognised as a subspecialist area of interest within our specialty and many procedures such as arthroscopy, arthroplasty, and replacement of the TMJ are becoming increasingly centralised and restricted to certain regions. We previously made a national survey of trainees and have sought to augment this with a survey of trainers to find out the nature of practice and patterns of referral nationally. We have also examined the consultants' expectations of competent final-year trainees...

We evaluated the effects of chitosan membrane, a highly absorbable and viscous material, in the prevention of intra-articular adhesions after anchoring of the disc in the temporomandibular joints (TMJ) of six adult goats (12 joints). To simulate anterior displacement of the disc and TMJ trauma, we cut off the retrodiscal attachment and damaged the surface of the condylar bone, then randomly divided the goats into two groups: the control group (n=2) and the experimental group (n=4). In the experimental group we covered the condylar surfaces on both sides of the animals with chitosan membranes...
