Introduction:
Submandibular gland pleomorphic adenoma is rare in children, and data regarding the optimal surgical approach remain limited. This study evaluated the feasibility, perioperative outcomes, and postoperative complications of transoral submandibular gland excision for pediatric pleomorphic adenoma.
Methods:
A retrospective review was conducted of pediatric patients who underwent transoral excision of submandibular gland pleomorphic adenoma between January 2023 and December 2024. Patients aged 18 years or younger with histopathologically confirmed pleomorphic adenoma treated via a transoral approach were included. Demographic characteristics, tumor size, operative time, length of hospital stay, postoperative complications, cosmetic satisfaction, and recurrence were analyzed.
Results:
Sixteen patients were included. The mean age was 11.6 ± 2.8 years, and the mean tumor diameter was 2.4 ± 0.6 cm. All patients underwent successful transoral excision without conversion to a transcervical approach. The mean operative time was 42.6 ± 11.6 min, and the mean length of hospital stay was 4.5 ± 1.2 days. The mean cosmetic satisfaction score was 9.1 ± 0.6 at 3 months postoperatively. Transient lingual nerve dysfunction occurred in five patients and resolved spontaneously in all cases. One patient developed a postoperative abscess, and one experienced transient limitation of tongue movement; both resolved without long-term sequelae. No permanent lingual, hypoglossal, or marginal mandibular nerve dysfunction, hematoma, residual gland tissue, or local recurrence was observed.
Conclusion:
Transoral submandibular gland excision may be a feasible, safe, and cosmetically favorable approach for carefully selected pediatric patients with pleomorphic adenoma. Careful patient selection, meticulous surgical technique, and long-term follow-up remain essential.
