Use of the myocutaneous serratus anterior free flap for reconstruction after salvage glossectomy.

PURPOSE

To describe the use of a myocutaneous serratus anterior free flap (SAFF) for tongue reconstruction after salvage subtotal (STG) and total glossectomy (TG).

METHODS

In this prospective case series, seven patients underwent salvage STG or TG and reconstruction with a myocutaneous SAFF between 10/2015 and 02/2017. Functional and oncologic outcomes were prospectively evaluated. Donor side morbidity was determined using the Disabilities of the Arm, Shoulder and Hand (DASH) score.

RESULTS

SAFF with mean skin paddles of 6.7 cm × 8.7 cm was used in five STG and two TG patients, respectively. There was a 100% flap survival and a mean DASH score of 10.8 reflected normal arm and shoulder function after surgery. One year after salvage surgery, 1 (14.3%) and 4 (57.1%) patients were tracheostomy and gastrostomy tube dependent. Gastrostomy tube dependence was significantly worse in patients with tumors of the base of tongue compared to other tumor sites (p = 0.030) and in patients who underwent transcervical compared to transoral tumor resection (p = 0.008). Local recurrence rate was 57.1% with a disease-free survival of 17.6 months.

CONCLUSION

The myocutaneous SAFF represents a safe and reliable flap for tongue reconstruction after salvage glossectomy with satisfying functional outcomes and low donor side morbidity.
