Submandibular suction lipectomy and single-hole inflator-free endoscopic thyroidectomy with a submental approach: a...

We have successfully carried out single-hole inflator-free endoscopic thyroidectomy through a submental approach, which has the advantages of less trauma, fewer complications, and hidden incisions. However, for patients with submandibular fat accumulation, submental incisions are not easy to hide, which directly affects the cosmetic effect. We developed a new surgical strategy "submandibular suction lipectomy and single-hole inflator-free endoscopic thyroidectomy with a submental approach" for these patients. We initially used submandibular suction lipectomy to reduce the accumulation of submandibular fat and obvious fat protrusion and, thus, restore the normal depression, placing the submental incision back where it is hidden in the submental shadow. Subsequentially, we began to use single-hole inflator-free endoscopic thyroidectomy with a submental approach. We aimed to explore the feasibility and cosmetic effect of this method for the treatment of thyroid disease patients with submandibular fat accumulation. The average operation time was 4.2 hours; and the average hospitalization time was 4.75 days. There were no postoperative complications, such as hoarseness, low calcium, hand and foot numbness, etc., and no special complications and no recurrence or metastasis seen in the 6-month follow-up examination. The aesthetic satisfaction survey results of patients half a year after surgery were satisfactory and above. For thyroid cancer patients with submandibular fat accumulation, this method not only hides the surgical incision in the neck but also meets the patient's requirement for "submental aesthetics"; thus it has good application prospects. It should be pointed out that the current findings are preliminary results, based on data from only four patients.
