Objectives/hypothesis: The aim of this study was to present our experience with management of malignant lesions arising within the masticator space, and to describe a technique of en bloc resection and reconstruction.
Study design: Case series and case report.
Methods: Eight cases of masticator space malignancies treated surgically with en bloc resection and free flap reconstruction were retrospectively reviewed.
Results: Tumor extirpation was carried out through a parotidectomy approach with mobilization and protection of the facial nerve. Primary reconstruction was accomplished with vascularized bone containing free flaps, fibula (n = 4), scapula (n = 2), and scapula with latissimus dorsi muscle (n = 2). Mean follow-up was 62.5 months (range, 18-132 months).
Conclusions: En bloc resection of masticator space malignancies can be consistently accomplished through an extended parotidectomy approach. The defect is best reconstructed with a vascularized bone and soft tissue free flap. Favorable functional and aesthetic outcomes can be successfully achieved using the techniques described in this series.
Level of evidence: 4.
