RESUMEN

Introduction Mandibular fractures have the highest incidence next to nasal bone fractures of which condylar fractures account for one-third of it. Various approaches for condylar fracture include intraoral and extraoral approaches such as coronal, preauricular, postauricular, endaural, endoscopic, rhytidectomy, transparotid, submandibular, and retromandibular approaches. The purpose of this study was to evaluate the mini-preauricular incision in open reduction and internal fixation of condylar and subcondylar fractures of the mandible. Materials and methods Twenty patients with condylar fracture underwent open reduction and internal fixation under general anesthesia using a modified mini-preauricular incision and subdermal dissection approach. Parameters assessed were pain, mouth opening, occlusal derangement, accessibility of fracture site, duration of surgery, neurosensory deficit (facial nerve), postoperative edema, wound infection, wound dehiscence, and scar. Patients were followed up at an interval of one week, one month, three months, and six months. Results On comparing the parameters preoperatively and postoperatively, occlusal derangement, mouth opening, and pain showed statistical significance with a p-value of 0.01, while nerve weakness and scar assessment showed a high level of statistical significance with a p-value of 0.001. The anatomical reduction of the condyle and internal fixation with miniplates was easy when this approach was used. Patients showed transient facial nerve paralysis only. No permanent damage was noted. The resultant scar was aesthetically acceptable. Discussion The mini-preauricular approach is an effective and safe technique for open reduction and internal fixation of condylar and subcondylar fractures. This approach provided good access, good cosmetic results, and patient satisfaction. This approach resulted in very less morbidity to the facial nerve.
