Abstract

Purpose The purposes of this study are to describe our experience using a double mandibular osteotomy for access to the parapharyngeal space in vascular and tumor surgery and to report on the outcomes and complications of this procedure. Patients and Methods We designed and implemented a case series to review the medical records of all patients treated with a double mandibular osteotomy for parapharyngeal space access from 1994 to 2016. Patient demographic characteristics, indications for the procedure, outcomes, and complications were recorded. Results A total of 17 patients underwent a double mandibular osteotomy procedure for access to the parapharyngeal space during the study period. There were 7 men (41%) and 10 women (59%) comprising the cohort. The average age was 57 years (range, 29 to 75 years). The follow-up period ranged from 6 to 98 months (mean, 40 months), and 7 patients (41%) were tobacco users at the time of surgery. The most common indication was high internal carotid artery stenosis (n = 6) followed by carotid body paraganglioma (n = 3). Average blood loss was 186 mL, and there were no deaths during the study period. Eight postoperative complications were noted in 7 patients (41%). No procedures were aborted or compromised because of inadequate parapharyngeal space access. All patients showed clinical and radiographic signs of healing of the osteotomy sites. Conclusion The double mandibular osteotomy provides adequate access to the parapharyngeal space for effective tumor removal and high carotid surgical intervention with acceptable patient morbidity and complications.
