Use of Cone-Beam Computed Tomography in Performing Submandibular Sialolithotomy

Transoral Robotic Surgery in the Management of Submandibular Gland Sialoliths: A Systematic Review

This study aimed to systematically review the literature to determine the efficacy and safety of transoral robotic surgery (TORS) in the management of submandibular gland (SMG) sialolithiasis. PubMed, Embase, and Cochrane were searched for English-language articles evaluating TORS in the management of SMG stones published up to 12 September 2022. Nine studies with a total of 99 patients were included. Eight patients underwent TORS followed by sialendoscopy (TS); 11 patients underwent sialendoscopy followed by TORS and sialendoscopy (STS); 4 patients underwent sialendoscopy followed by TORS only (ST); and 4 patients underwent TORS without sialendoscopy (T). The mean operative time amounted to 90.97 min. The mean procedure success rate reached 94.97%, with the highest for ST (100%) and T (100%), followed by the TS (95.04%) and STS (90.91%) variants. The mean follow-up time was 6.81 months. Transient lingual nerve injury occurred in 28 patients (28.3%) and was resolved in all of them within the mean of 1.25 months. No permanent lingual nerve injury was reported. TORS is a safe and effective management modality for hilar and intraparenchymal SMG sialoliths, with high procedural success in terms of successful sialolith removal, SMG preservation, and reduced risk of permanent postoperative lingual nerve damage.

Outcomes of Submandibular Stone Removal With and Without Salivary Endoscopes

OBJECTIVES/HYPOTHESIS

For patients with submandibular sialolithiasis, there are many gland-preserving treatment options including sialendoscopy. Sialendoscopy, however, requires expensive instrumentation with limited availability, which may not be required for routine cases. The objective of this study is to compare the outcomes of patients with submandibular sialolithiasis undergoing sialendoscopy versus those undergoing transoral incisional sialithotomy.

STUDY DESIGN

Longitudinal, prospective study of patient undergoing gland-preserving therapy for submandibular sialolithiasis.

METHODS

The study was a prospective, nonrandomized trial of 30 patients with submandibular sialolithiasis who received gland-preserving treatment by either sialendoscopy-assisted techniques (Scope group; 14 patients) or transoral sialithotomy with or without dochoplasty (No Scope group; 16 patients). Factors analyzed between the two groups included age, race, gender, size of stone, location of stone, gland(s) involved, surgical method, and modified salivary Oral Health Impact Profile (sOHIP) scores before and after therapy.

RESULTS

There were no significant differences between the Scope and No Scope groups regarding age, race, or gender. There was a significant difference in stone size between the groups, with the No Scope group having larger stones on average. Both treatments led to statistically significant symptomatic improvement in sOHIP scores. There was no statistically significant difference in salivary quality of life improvement between the Scope and No Scope groups (P = .33).

CONCLUSIONS

Sialendoscopy is an important diagnostic and therapeutic tool in the management of salivary disorders, but is not associated with improved outcomes in gland-preserving treatments for routine submandibular sialolithiasis. Transoral stone removal alone may have equivalent symptomatic outcomes in the management of select sialoliths.
