NAME: XXXX XXXXXX MEDICAL RECORD #: XXXXXXX DATE OF SURGERY: XX/XX/XX SURGEON: XXXX XXXXXX, MD ASSITANT: XXXX XXXXXX, MD PREOPERATIVE DIAGNOSIS Mandibular symphysis osteotomy. Open wound at floor of mouth and buccal mucosa. POSTOPERATIVE DIAGNOSIS Mandibular symphysis osteotomy. Open wound at floor of mouth and buccal mucosa. PROCEDURE Repair with internal fixation and repair of soft tissue defect. ANESTHESIA General. OPERATIVE INDICATIONS This is a youngster with a history of neuroblastoma whom I had first seen 6 months earlier. At that time, the lesion presented as a neck mass, which was biopsied. Subsequent studies showed extensive involvement of the right neck and right cranial base, namely extension into the jugular foramen. The patient received neoadjuvant chemotherapy and is slated for radical en bloc excision today. OPERATIVE PROCEDURE Through the mandibular-splitting approach, a radical neck dissection with en bloc resection of the tumor from the cranial base around the jugular foramen was carried out without complication after tracheostomy had been performed. The right floor of the mouth incision, extending from the posterior middle third of the tongue up to the anterior floor of the mouth, was closed with interrupted sutures of Vicryl, with care being taken to maintain a watertight closure. The mandibular symphysis osteotomy was carried out through the socket of the extracted right mandibular central incisor halfway down the vertical height of the symphysis and then stairstepped to the left and then down across the mandibular border. Care was taken to preserve both mental nerves bilaterally. The horizontal portion of the osteotomy had necessarily coursed through 2 tooth buds of the permanent dentition, and these were subsequently debrided. An anatomic approximation of the symphysis was carried out and held in place while a 2.0 compression plate made of titanium was applied to the lower rim of the symphysis. Good solid bony union was achieved. The mucosa, both labial and gingival of the lower lip were then reapproximated with 5 interrupted sutures of Vicryl. The gingiva was then brought up to the tooth crowns and secured into the mucosa in the anterior floor of the mouth with sutures. These sutures encircled the teeth and created a nice watertight seal, with no exposure of the underlying mandible. The lip was then prepared, and the remainder of the neck closure was carried out by Dr. Fischer.
