Abstract
Endoscope-assisted surgery is becoming a preferred technique in salivary gland surgery.
However, this technique has not yet been applied in submandibular gland (SMG) preservation
surgery. This retrospective study was performed to evaluate the outcomes of endoscope-assisted
gland-preserving surgery through a hairline incision in patients with benign SMG tumours.
The study included 38 patients with benign SMG tumours who underwent tumour excision
with gland preservation: 19 who underwent local excision of the tumour through an
endoscope-assisted hairline approach and 19 who received the conventional cervical
approach. The feasibility of the surgical procedure, perioperative patient variables,
and postoperative appearance and functional outcomes were evaluated. Patients in both
groups had their tumours removed successfully with tumour-free margins. The intraoperative
blood loss, postoperative amount of drainage, mean length of the incision, and unstimulated
saliva flow rate did not differ between the two groups. There was no difference in
the stimulated saliva flow rate between the preserved gland and unaffected SMG. The
aesthetic result was better in the endoscope-assisted hairline incision group. No
tumour recurrence occurred during follow-up (range 12–52 months). Thus, gland-preserving
tumour dissection appears to be a safe method for benign SMG tumours, with good functional
results. Furthermore, the endoscope-assisted hairline incision is a feasible method
with excellent cosmetic results.
