Gland‐preserving surgery for salivary stones and the utility of sialendoscopes

Abstract

Background

Sialoendoscopy is the standard treatment for sialolithiasis; however, some patients may be unlikely to benefit from an endoscopic approach. This study assesses predictors of failure in the endoscopic management of sialoliths.

Methods

Patients treated for sialolithiasis from 2012 to 2017 at two centers were stratified into 3 groups: successful interventional sialendoscopy, incisional sialolithotomy, and gland excision. Patient, disease, and surgical factors were compared.

Results

Interventional sialendoscopy was attempted in 156 of 206 cases and successful for 42 (27%). Endoscopically retrieved calculi were smaller (4.96 mm) compared to incisional sialolithotomy (7.90 mm). Nonendoscopic approaches were required more often in submandibular cases 87% (P ≤ .005). Palpable stones were present in 74% of incisional sialolithotomies (P < .001). Submandibular location (OR 3.50, 1.53‐7.98), palpability (OR 2.74, 1.21‐6.18), CT localization (OR 3.05, 1.32‐7.10, P = .010), and increased diameter (OR 1.25, 1.09‐1.44) were predictive of incisional management.

Conclusion

Stone size/location, CT‐localization, and palpability were predictive of calculi that require an incisional approach. If these factors are recognized, the surgeon can consider proceeding directly to incisional sialolithotomy.

Level of evidence
