Reconstructive strategies following surgical resection of malignant sublingual gland tumors: A single institution experience.

[OBJECTIVE] To investigate the characteristics and treatment modalities of malignant tumors originating from the sublingual gland, as well as evaluate the therapeutic outcomes following free flap reconstruction.

[METHODS] A retrospective statistical analysis was conducted on the clinical data of nine patients diagnosed with malignant neoplasms tumor of the sublingual gland.

[RESULTS] Nine case of malignant tumors originated from the sublingual glandular tissue, encompassing eight adenoid cystic carcinoma (ACC) and a single case of bipartite differentiated carcinoma-a hybrid of epithelial-myoepithelial carcinoma and adenoid cystic carcinoma. Among the nine patients, four anterolateral thigh flaps were used (three of which were thin flaps), and five forearm flaps were also empoyed. The size of flaps varied, with the lengths ranging from 4 cm to 9 cm, and the widths ranging from 2.5 cm to 6 cm. The vessels chosen for anastomosis were the superior thyroid artery in seven cases, the facial artery in one case, and the lingual artery in one case. Among the eight patients who underwent dissection of cervical lymph nodes, metastasis were found in one case. Two patients underwent adjuvant radiotherapy. Upon postoperative follow-up, there was no recurrence in any of the nine patients .

[CONCLUSION] The anterolateral thigh perforator flap thinning technique can be employed for postoperative reconstruction of malignant sublingual gland tumors.
