subcondylar fracture

Among all mandibular fracture 25.0 to 40.0% fractures are regarded as condylar and subcondylar fracture. Commonly, reduction of subcondylar fracture is done under general anaesthesia. Different approaches were found for the surgical treatment of condylar fractures besides intraoral approaches such as the pre-auricular, submandibular, rhytidectomy, retromandibular. This is a prospective observational study which was performed to find out the outcome of retromandibular approach for subcondylar fracture treatment of mandible i...

BACKGROUND: Mandibular subcondylar fractures can be fixed with 2 titanium plates or 2 resorbable plates. However, when a wider resorbable plate is used, there might be insufficient space on subcondylar region. The authors have tested the back of the condyle as an alternative location for the wide resorbable plate. METHODS: The fractured condyle was accessed through the preauricular approach. The first resorbable plate (4 hole plate, extended; 2 mm Inion OTPSTM) was contoured around the posterior edge of the mandibular ramus...

Although closed reduction is common for condylar fractures, bone fragments may heal improperly. This study aimed to investigate the healing morphology of unilateral condylar fractures. We retrospectively investigated 70 patients with unilateral condylar fractures. Clinico-statistical analyses were performed on the whole-condylar fracture, closed reduction, and observation/functional therapy groups. Among these patients, 52 patients aged older than 16 years underwent closed reduction. The extent of maximum mouth opening, the incidence of malocclusion, and the relationship between healing morphology and Arbeitsgemeinschaft für Osteosynthesefragen classification or trismus were analyzed in the closed reduction group...

AIM: In 2006 following the development of dedicated osteosynthesis plates, Meyer and colleagues reported a successful clinical study of condylar fractures treated by a modified submandibular approach; it was called high submandibular approach or "Strasbourg approach." The aim of this study is to describe the high submandibular approach step by step. CASE SERIES: Between January 2010 and December 2015 at the Maxillofacial Unit of the Hospital "Policlinico San Martino" 13 patients affected by subcondylar fracture underwent open reduction and internal with high submandibular approach...

Condylar fractures alone accounts to about 25% to 40% of all the fractures of mandible. Management of condylar fractures has always been a controversy. Nowadays there has been more emphasis on open reduction of condylar fractures by the surgeons.The reasons could be the result of complications of closed reduction where the patient may not be able to masticate properly and deviation still present thereby the structural and functional loss forcing the surgeons' choice to open up. The anterior parotid approach has lesser risk of injury to parotid gland and also to facial nerve we attempted to use mini retro mandibular access for such fractures...

BACKGROUND: There are several indications for partial or total replacement of the temporomandibular joint (TMJ), including neoplasms and severe bone resorptions. In this regard, several techniques have been suggested to increase the functionality and longevity of these prosthetic devices. This case report describes the treatment of a TMJ ankylosis patient with the Puricelli biconvex arthroplasty (ABiP) technique, with a long-term follow-up. CASE PRESENTATION: In 1978, a 33-year-old male polytraumatised patient developed painful symptoms in the right preauricular region, associated with restricted movement of the ipsilateral TMJ...

In lieu of a lack of consensus among the global community, it becomes imperative to address the pitfalls in the surgical management of bilateral mandibular condylar fractures with the contemporary technique of open reduction and internal fixation of only one side. This dictum inevitably leads to postoperative complications despite the best efforts of the surgical team to optimize care. We present a case series comprising residual deformities and complications arising out of the inadequate treatment of bilateral condylar fractures...

Aim: To carry out clinical in vivo evaluation of efficiency of the 2-mm lambda plate for open reduction and internal fixation of condylar fractures. Materials and Methods: This prospective clinical study was conducted on a group of 16 patients who underwent open reduction for subcondylar fractures of the mandible and fixation using a 2-mm 7-holed titanium lambda miniplate. Results: The average surgical time was found to be 79.5 min. The ease of access was found to be adequate in 13 cases (81...

Background: Osteogenesis imperfecta (OI) is a rare metabolic bone disorder in which collagen production is impaired. Patients have brittle bones that are prone to fracture with minor trauma. Whereas most of the fractures occur in the spine and extremities, fractures of the craniofacial bones are less common. Methods: This report describes the management of a 14-year-old boy with OI type 1 who sustained mandible fractures from an assault. Management consisted of open reduction and internal fixation of the parasymphyseal and angle fractures and closed reduction and mandibulomaxillary fixation of the subcondylar fracture...

Pediatric subcondylar jaw fractures in the mixed dentition phase present a unique challenge as immobilization of the jaw is indicated but arch bars are contraindicated due to fear of damage to underlying tooth buds. No definite guidelines are present in the management of pediatric subcondylar jaw fractures. We report a case in which a patient in mixed dentition with undisplaced fracture of neck of condyle which was managed with Intermaxillary fixation. How to cite this article: Tirupathi SP, Rajasekhar S, Ganesh M, et al...

In this study, we introduced a small "V" shaped incision around the ear lobe modified from fact-lift approach to treat the mandibular condylar neck and subcondylar fractures to further minimize and hide the postsurgical scars. A total of 15 cases with mandibular condylar fractures from low levels of condylar neck to high levels of subcondylar region were treated by this approach. An incision was designed from the posterior rim of the tragus down to the anterior skin wrinkle to the ear lobe, surrounding it, continually up and backward for a little distance, forming a "V"-like shape...

PURPOSE: The aim of this study was to review retrospectively the functional recoveries of subcondylar fracture patients that underwent open reduction surgery using an extraoral approach or an intraoral approach using a trans-buccal trocar and involving ramus buccal decortication. MATERIALS AND METHODS: Of 47 patients with mandibular condyle fracture who visited Pusan National University Dental Hospital Department of Oral and Maxillofacial Surgery between May 2015 and November 2020, 38 patients underwent open reduction and were classified according to the surgical method used...

PURPOSE: This paper is intended to compare and evaluate the better treatment option in the management of subcondylar fractures of the mandible. MATERIALS AND METHODS: This study included 20 patients who were diagnosed clinically and radiologically to have sustained an isolated subcondylar fracture of the mandible. They were divided into two groups randomly. Group I included 10 patients who underwent treatment by intermaxillary fixation alone followed by active physiotherapy in the form of conservative management...

This study aimed to evaluate the reliability of a trapezium plate for open reduction and internal fixation (ORIF) of mandibular subcondylar fractures with the simultaneous use of an endoscope. We selected and retrospectively studied 18 patients (12 males and 6 females) with unilateral mandibular subcondylar fractures who visited the Wonju Severance Christian Hospital. The mean age of the patients was 43.43 ± 15.76 years. Patients underwent ORIF with trapezium miniplate application through an intraoral incision under general anesthesia...

The purpose of this study was aimed to compare the efficiency and safety of retromandibular versus modified Risdon approach using periangular incision for open reduction and internal fixation of low subcondylar mandibular fracture. Open reduction and internal fixation with different plating systems were utilized via retromandibular approach (group I) and via modified Risdon approach with periangular incision (group II). Twenty four (n= 24) condylar fractures in 21 adult patients were divided randomly into two equal groups (12 each) according to the cutaneous incision (approach) utilized...

The aim of this study was to investigate whether life-like fractures of human cadaveric mandibles with a focus on the condylar process and the intact soft tissue envelope could be simulated. A total of nine fresh-frozen human head specimens were fractured in a custom-made drop-test bench. This reproducible method is based on a weight falling from a defined height onto the fixed specimens, simulating a direct blow to the symphysis of the mandible. All the fractures were analyzed by fluoroscopy and CT-scans. In all the specimens that were included in this study, several typical lesions could be created, resulting in a total of 27 mandible fractures...

Mandibular symphysis fractures pose several technical challenges for the craniomaxillofacial surgeon. One classic challenge is restoration of the transverse dimension when the mandible is widened secondary to splaying of the lingual cortex. Failure to diagnose or correct this problem can result in widening of the lower facial third, inadequate fracture reduction, and/or a malocclusion. Surgeons have traditionally utilized techniques such as manual pressure to the rami or lingual splint application to address transverse defects intraoperatively...

The dilemma regarding the management of condylar fractures generally revolves around the surgical approach, implant design, and the surgeon's experience. Zide and Kent's guidelines streamlined the decision making process for condylar fractures. However, there exists no standardized protocol for reduction and fixation of condylar fractures. Here, we have described a detailed and stepwise protocol, common to any surgical approach, that would lead to predictable, reproducible, and repeatable results in every surgeon's hands...

BACKGROUND: Many types of titanium plates were used to treat subcondylar fracture clinically. However, the efficacy of fixation in different implant positions and lengths of the bone plate has not been thoroughly investigated. Therefore, the primary purpose of this study was to use finite element analysis (FEA) to analyze the biomechanical effects of subcondylar fracture fixation with miniplates at different positions and lengths so that clinicians were able to find a better strategy of fixation to improve the efficacy and outcome of treatment...

Salivary gland and duct complications following surgical approaches to condylar fractures are well known, particularly in approaches requiring parotid tissue dissection. We report a rare case of a parotid duct wound caused by the fracture itself and due to a lateral displacement of the condylar fragment. Four days after the surgical management of a trifocal mandibular fracture (head fracture on the left side, laterally displaced condylar base and angular fracture on the right side) the patient presented with a fluctuating subcutaneous swelling in the right cheek, evoking a sialocele...
