title: Submental island flap reconstruction in oral cavity cancer patients with level I lymph node metastasis.
abstract: The submental island flap is useful as an alternative to microvascular free tissue transfer for the reconstruction of defects after resection of oral cancer because it is simple to harvest, reliable, and is associated with good oral function and low morbidity. However, because cancer of the oral cavity carries a risk of level I nodal metastases, the oncological safety of the flap remains controversial. Between April 2012 and September 2016, we studied patients with squamous cell carcinoma of the oral cavity who had surgical resection with submental island flap reconstruction for viability of the flap, signs of recurrence, and complications. Thirty-five patients (22 men and 13 women) were enrolled in the study and the mean (range) duration of follow-up was 23 (11-48) months. Six patients had local recurrences of their tumours, none of which was considered to be related to the flap. No flap was lost completely, but there were 10 cases of partial skin loss that healed with conservative management. There were no orocutaneous fistulas, haematomas, or marginal mandibular nerve palsies. We conclude that the submental island flap can be used safely in selected patients with level I lymph node metastases when the flap has been harvested meticulously.
