Delayed complications after anterior craniofacial resection of malignant skull base tumors.

Objective To report complications occurring at least 6 months after completion of treatment for patients with anterior skull base malignancy undergoing anterior craniofacial resection (CFR). Design Retrospective review of medical records of all patients undergoing traditional CFR for treatment of anterior skull base malignancy from 2002 through 2011. Setting Massachusetts General Hospital/Massachusetts Eye and Ear Infirmary Cranial Base Center. Participants Thirty-one consecutive patients who had at least 18 months of follow-up for analysis were reviewed. All patients underwent traditional CFR. A total of 28 patients received postoperative proton beam radiation therapy. Eleven patients received adjuvant chemotherapy. Main Outcome Measures A delayed complication was any complication occurring at least 6 months after the completion of treatment. Results Seventeen patients had delayed complications. Orbital complications were the most common type (13 patients) followed by issues with wound healing (6 patients). The most common orbital complication was epiphora (7 patients). The most common wound complication was a nasocutaneous fistula (5 patients). Conclusions Patients with anterior skull malignancy can develop complications months to years after the completion of treatment. Therefore, it is important to continue to follow and report complications for several years when deciding on the optimal approach for treatment of these patients.
