BACKGROUND: Arthrocentesis has an effect of washing out inflammatory products that accumulate in the joint compartment of a dysfunctional TMJ. The procedure removes inflammatory cytokines, which are pain-causing substances, for early reduction of TMJ pain and quick recovery of jaw function, thus increasing the possibility of a successful rehabilitation. OBJECTIVE: The aim of the present study was to investigate the relationship between arthroscopy synovitis grade in patients with unilateral high condylar fractures and concentrations of the pro-inflammatory cytokines tumor necrosis factor (TNF)-alpha as well as of matrix metalloproteinases (MMPs) in washed-out synovial fluid (SF) samples obtained from those patients...

Background: Temporomandibular joint (TMJ) ankylosis is one of the most disruptive maladies afflicting the masticatory system. The characteristic feature is the formation of bony mass bridging condyle with glenoid fossa. The exact pathogenesis is, however, not completely understood. Purpose: To investigate and compare histomorphometric features of ankylosed condylar specimen with normal condylar process. Materials and Methods: Group I included 17 post-traumatic unilateral TMJ ankylosis patients managed by excision of ankylosed mass and interpositional arthroplasty...

OBJECTIVE: Condylar and subcondylar fractures (CSFs) are among the most common mandible fractures. If reduction of these fractures is not carried out correctly, serious complications can result, including infection, damage to temporomandibular joint (TMJ) function, malocclusion, nonunion, malunion, and ankylosis of the TMJ. METHODS: We used a preauricular, mini-incision, open technique (PMIOT) for CSF of the mandible. 66 patients (48 males, 18 females), with a total of 72 CSFs of the mandible, were repaired with PMIOT between 2011 and 2016...

Introduction: Condylar fractures of the mandible are functionally important fractures as the condyle of the mandible being a part of the temporomandibular joint (TMJ) and can lead to TMJ dysfunction if not properly treated. Materials and Methods: This was a cross-sectional study of a total of 33 treated patients with fracture of the mandibular condyle who underwent examination as per the Helkimo index. Their dysfunction was quantified and clinicoepidemiological characteristics were assessed...

OBJECTIVES: In this study, we tried to explore the effects of a single condylar neck fracture without condylar cartilage injury during the pathogenesis process of traumatic heterotopic ossification around the temporomandibular joint (THO-TMJ). STUDY DESIGN: One-month-old C57 BL/6 J male mice were divided into 2 groups. In group 1, condylar cartilage was partially removed in the right joint to induce THO. In group 2, a single fracture on the condylar neck was created using small scissors...

OBJECTIVE: To explore the selection of temporomandibular joint (TMJ) disc reduction and fixation methods in condylar sagittal fracture surgery. METHODS: A total of 36 patients with condylar fractures were chosen. The follow-up period was more 6 months. All 36 cases of condylar sagittal fracture were fixed with long screw. In the operation, the displaced joint disc was repositioned and fixed. The fixed method included direct suture (22 cases) and anchorage (14 cases)...

Total condylar resorption and the failure of bone synthesis material as postoperative complications of condyle fracture are seldom reported in the literature. When these occur, they may severely limit temporomandibular joint (TMJ) function. In such cases, a reconstruction of the joint is indicated, which can be achieved by means of an alloplastic prosthesis. This article reports a rare case of impaction of osteosynthesis material in the region of the base of the skull associated with a mandibular condyle fracture treated with rigid internal fixation, which resulted in complications...

Management of condylar head fractures (CHF) of the temporomandibular joint (TMJ) remains a source of controversy. Based on established literature, group of CHFs and conservative treatment connected with period of maxillomandibular fixation (MMF) increases the risk for TMJ ankylosis. This paper presents anatomical and functional results of surgical treatment of condylar head fractures in a group of 24 patients (29 joints). Fractures were diagnosed based on conventional radiographs and computed tomography (CT) scans...

OBJECTIVES: Differential diagnosis of bifid mandibular condyle (BMC) is important, since it may play a role in temporomandibular joint (TMJ) dysfunctions and joint symptoms. In addition, radiographic appearance of BMC may mimic tumors and/or fractures. The aim of this study was to evaluate the prevalence and orientation of BMC based on cone beam computed tomography (CBCT) scans. MATERIALS AND METHODS: This cross-sectional study was performed on CBCT scans of paranasal sinuses of 425 patients...

A prospective cohort study was performed to investigate concurrent and delayed temporomandibular joint (TMJ) injuries following different types of mandibular fracture using magnetic resonance imaging (MRI). One hundred adult male patients with a recent history of mandibular fracture were included. The patients were divided into five groups according to the site of fracture. The patients underwent MRI within 10 days of the primary injury. The same clinical, radiographic, and MRI examinations were performed 5 years later...

BACKGROUND: The pathogenesis of traumatic TMJ ankylosis remains unclear. This study aimed to verify the role of the lateral pterygoid muscle in the pathogenesis of traumatic temporomandibular joint (TMJ) bony ankylosis. METHODS: Eight 6-month-old male sheep were used in this study. Bilateral TMJ osteotomies were performed to induce sagittal fractures of the mandibular condyle. The lateral one-fourth segment of the disc was removed to establish a model of TMJ bony ankylosis...

The aim of this study was to investigate the bone resorption effect of the mediators delivered in joint cavity of patients with mandibular condyle fractures by detecting osteoclast markers using cellular biochemistry methods, and by analysing bone resorption activities via inducing osteoclast differentiation of the infiltrated cells from arthrocentesis. Sixteen joints in 10 patients with mandibular condyle fractures were evaluated. The control group consisted of synovial fluid (SF) samples from seven joints of four volunteers who had no clinical signs or symptoms involving the temporomandibular joint (TMJ) or disc displacement...

To evaluate the displacement of the disc of the temporomandibular joint (TMJ) in different types of condylar fracture we studied 160 patients (222 joints) from May 2009-June 2014. All patients had computed tomographic scans (CT) and magnetic resonance images (MRI) taken preoperatively, and 24 patients (32 joints) had MRI postoperatively. CT scans were reviewed to categorise the types of condylar fracture (intracapsular, condylar neck, and subcondylar), and intracapsular condylar fractures were further classified into subtypes A, B, C, and M...

BACKGROUND: Temporomandibular joint (TMJ) ankylosis due to undiagnosed condylar fractures has a high incidence in India compared to western countries. We evaluated the demographics, injury pattern, hospital reporting and referral pattern of undiagnosed condylar fractures complicating TMJ ankylosis in northern India. METHODS: We did a retrospective analysis by retrieving medical records of patients with post-traumatic TMJ ankylosis reporting to the Department of Oral and Maxillofacial Surgery, All India Institute of Medical Sciences between 1 July 2012 and 30 June 2013...

Mandibular condylar fractures are common presentations to hospitals across the globe and remain the most important cause of temporomandibular joint (TMJ) ankylosis. This study aimed to analyze cases of mandibular condylar fracture complicated by TMJ ankylosis after treatment. A 16-year retrospective analysis was performed at the dental and maxillofacial surgery clinic of the study institution; patient data were collected from the hospital records and entered into a pro-forma questionnaire. It was found that 56/3596 (1...

INTRODUCTION: In a condylar fracture whether to intervene or to go for conservative management still remains a dilemma. Studies and hypothesis suggests that it's medially dislocated condylar fracture segment that is more likely to ankylose, moreover no consensus have been put forth as to whether to remove the medially displaced fracture segment. PRESENTATION OF CASE: The current article describes a case of unilateral temporomandibular joint (TMJ) ankylosis, which resulted as a sequlae from conservative management of a bilateral condylar fracture of which, the ankylosed side had a sagittal fracture of condyle...
