ObjectiveTo evaluate safety, effectiveness, and long-term gland function of endoscopy-assisted lithectomy for parotid gland calculusStudy designOverall, 116 consecutive patients with parotid gland calculus underwent endoscopy-assisted lithectomy at our center. The immediate safety and effectiveness were evaluated. After surgery, the patients were followed up, and gland function was analyzed by clinical manifestations and sialography.ResultsComplete stone extraction was achieved in 110 cases (94.8%, 110/116) by using a transoral (95 cases) or transcutaneous (15 cases) approach. At a median follow-up of 3 years, clinical outcomes were excellent in 86 cases (78.2%), fair in 16 cases (14.5%), and poor in 5 cases (4.5%). Postoperative sialographic appearance in 30 stone-free patients was categorized into 3 types: (1) normal (13 cases); (2) the main duct had ectasia or stenosis, but no persistent contrast was seen on functional films (10 cases); and (3) the main duct had ectasia or stenosis, and persistent contrast was evident on functional films (7 cases).ConclusionsIn the absence of lithotripsy, appropriate application of various minimally invasive endoscopic procedures confirms safety and effectiveness of stone extraction for parotid calculi. Sialography is a viable method for evaluation of postoperative gland function.
