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.e. to find out correction of occlusion and establishment of jaw function, infection, hematoma, salivary fistula, facial nerve damage, haematoma etc complication. Surgical treatment of subcondylar fractures of 15 patients was done in Dhaka Dental College and Hospital and different private centres in Dhaka and Mymensingh, Bangladesh from January 2019 to December 2021 in retromandibular transparortid approach. The patients were evaluated for hematoma, infection, Frey's syndrome, salivary fistula, facial nerve damage, occlusion, fracture site stability, chronic pain in the fracture site and temporomandibular joint movements in the post operative period. Facial nerve injury was not observed. Postoperative swelling of parotid region developed in first two patients. Single patient developed paresis in zygomatic branch of facial nerve causing left upper eyelid muscle weak and after two weeks of physiotherapy it became normal. Salivary fistula developed in three patients which resolved spontaneously. Outcome of this approach like good anatomy and function was found in all cases. Good articular function was obtained in all the cases. By this retromandibular approach condylar fracture reduction; fixation and healing were managed comfortably. However, direct vision of facial nerve fibres has limited the risk of facial nerve injury.
