Functional reconstruction of tissue defects after total parotidectomy using a modified submandibular gland flap

Objective

Reconstruction of soft tissue defects after total parotidectomy requires a feasible and effective pedicled flap with sufficient volume. In this study, we introduce a modified submandibular gland flap (SMGF) for functional reconstruction of soft tissue defects resulting from total parotidectomy.

Materials and Methods

This study included 12 patients diagnosed with parotid gland carcinoma undergoing total parotidectomy and ipsilateral selective neck dissection. The modified SMGF was harvested and transferred to the parotid bed. This procedure was coupled with anastomosis between the parotid gland duct and Wharton's duct. The feasibility of the surgery, postoperative complications, facial profile restoration, and salivary secretion were assessed.

Results

All SMGFs pedicled only over the proximal facial artery survived without major complications. Facial profiles were well-restored, and salivary secretion was partially reserved. During the postoperative follow-up, no tumor recurrence was observed in any of the cases, and the volume of the SMGFs did not show obvious atrophy.

Conclusions

The modified SMGF is a viable solution for volume restoration and functional reconstruction after total parotidectomy.

Clinical Relevance

This modified technique is simple and feasible for the functional reconstruction of soft tissue defects after total parotidectomy compared to other flaps and is worthy of clinical promotion.
