RESUMO
Vocal cord paralysis after administration of the chemotherapeutic agent vincristine is a rare occurrence. Most occurrences are bilateral. Of the 24 cases referenced in this article, 19 are children. In all the reported cases, symptoms have occurred after multiple doses of vincristine have been administered. The authors report a case of a 39-year-old woman with unilateral vocal cord motion impairment occurring 3 days after the administration of the first dose of vincristine. This is the first case of vocal cord motion impairment reported after the administration of only 1 dose of this drug.

The free fibula flap is the preferred reconstructive method for oncologic defects of the mandible. Arterial inflow of the extremity is routinely evaluated with several modalities; however, venous screening is rarely performed. Patients with cancer are at elevated risk of occult deep venous thrombosis (DVT). An asymptomatic thrombus encountered during free fibula reconstruction is a serious concern. Although such cases have been reported, we suspect the incidence of DVT during fibula free flap harvest is underappreciated. This monograph uses a case example to review risk factors for occult DVT, present a strategy for preoperative assessment, and provide a reconstructive algorithm to for mandibular reconstruction in such instances.
