Abstract
Objective
To describe the management, technical nuances, and success rates of transoral robotic surgery (TORS)–assisted sialolithotomy.
Study Design
Retrospective database review.
Setting
Quaternary academic medical center.
Methods
Between the months of January 2015 and May 2019, patients with hilar submandibular gland stones underwent 2 main variations of TORS-assisted sialolithotomy and sialendoscopy: (1) TORS followed by sialendoscopy for patients with palpable predominantly single stones and (2) either sialendoscopy followed by TORS and sialendoscopy or sialendoscopy followed by TORS only for patients with nonpalpable or multiple stones. Clinical charts were reviewed to collect data, including stone size (imaging review, intraoperative measurement), palpability, duration of operation, TORS variation, operative challenges, symptom improvement, gland preservation rate, and complications.
Results
Thirty-seven patients were identified. Patients were 26 to 80 years old (mean, 57.2 years), and 40.5% were female. Twenty-four patients (64.9%) underwent TORS followed by sialendoscopy; 10 (27.0%), sialendoscopy followed by TORS and sialendoscopy; and 3 (8.1%), sialendoscopy followed by TORS only. The mean stone size was 12.4 mm (range, 4-28 mm). Eleven patients had multiple stones with a mean 4 stones per patient (range, 2-9). Procedural success was 91.9% (34/37) at a mean follow-up of 34.2 weeks (range, 1.4-262.1), and the gland preservation rate was 97.3% (36/37). No patients reported symptoms of lingual nerve injury at 3-month follow-up.
Conclusion
TORS combined with sialendoscopy for hilar submandibular gland sialolithiasis allows for improved visualization of critical anatomy, tissue manipulation, and operative flexibility. In our experience, the operative success rate is high, and duration of surgery compares favorably with conventional combined hilar approaches.
