Scarless Modified Approach to Subcondylar Fracture Bypassing the Parotid Gland- A Case Report

Subcondylar fractures contribute about 19-29% amongst all the mandibular fractures worldwide, yet the treatment paradigm remains slightly controversial. Subcondylar fractures are pivotal in maxillofacial surgery for diverse reasons, as they can result in number of complications, whether treated or not. Initial clinical outcomes may appear pragmatic but complications such as pain, restrictions of jaw movements, muscle spasm, mandibular deviation, malocclusion, and facial asymmetry may become apparent. Fracture of tympanic part, mandibular fossa of temporal bone, may or may not be escorted by dislocation of condylar segment into middle cranial fossa, damage to blood vessels, arteriovenous fistula are some additional complications. Choosing right surgical strategy is a for minimising postoperative complications management of subcondylar fractures and it should be taken in account that, perioperative, functional, and patient-reported outcomes. The majority of studies that have been published describe the use submandibular, retromandibular, or preauricular incisions have drawbacks such as poor visibility, accessibility, and the potential to harm facial nerve and complications related to the parotid gland. Hereby, the authors present a case report of left subcondylar fracture in a 55-year-old, male patient, where a modified percutaneous approach was taken, to access the fracture, and aid in adequate reduction and proper fixation without any postoperative complications. In this approach, parotid gland is bypassed and masseter muscle fibres are excised to reach the fractured site at subcondylar region. It is small, straight forward, elementary, safe, reliable and scarless approach for the management of subcondylar fractures that ensures adequate exposure of the fractured site, osteosynthesis and minimal potential postoperative complications.

Temporomandibular Joint Ankylosis In Children

Temporomandibular joint (TMJ) ankylosis is defined as osseous or fibrous fusion of the condyle of the mandible and the mandibular fossa of temporal bone (Nitzan et. al. 1998).It is a debilitating disease that renders the afflicted person unable to use their oral cavity well. Clinical presentation depends on the age at which ankylosis occurs and whether ankylosis is unilateral or bilateral. Surgery and postoperative physiotherapy are regarded as the mainstay treatment for TMJ ankylosis. The study reviews surgical outcomes of 13 children treated for temporomandibular joint (TMJ) ankylosis in the maxillofacial and oral surgery unit at Red Cross Children's Hospital. Nine patients were treated by gap arthroplasty, while four patients had previous reconstruction with costochondral graft. One patient treated by gap arthroplasty reankylosed. The study showed a positive correlation between intraoperative MIO and the outcome, and between age and the outcome. Mouth opening was improved by 15mm, with postoperative change of -4mm.
