Neurotization of the radial forearm free flap improves swallowing outcomes in hemiglossectomy defects.

BACKGROUND

We examined the effect of free tissue neurotization on speech and swallowing outcomes for patients undergoing reconstruction of hemiglossectomy defects with a radial forearm free flap (RFFF).

METHODS

A retrospective study was performed in patients with oral cavity squamous cell carcinoma undergoing a hemiglossectomy and reconstruction with a RFFF. Functional outcomes including nutritional mode, range of liquids and solids, and speech understandability were analyzed 1-year post-treatment.

RESULTS

Eighty-four patients were included in this analysis, 41 of whom had neurotized flaps (49%). No significant differences in demographic or clinical variables were seen between the neurotized and non-neurotized groups. On multivariate analysis controlling for BMI, flap area, and N-classification, patients with neurotized flaps were significantly more likely to have normal range of liquids and solids and less likely to have a G-tube.

CONCLUSIONS

Neurotization of RFFF reconstructing hemiglossectomy defects results in decreased G-tube dependence and improved range of liquids and solids.
