Objectives To assess the long-term outcome of sialendoscopy-assisted combined approach for parotid sialolithotomy with gland preservation. Patients and methods A retrospective study of patients treated with a combined sialendoscopic and open approach was conducted between 2011 and 2020. Demographic data of patients such as operative technique, stone size, stone location, complications, and symptom relief were collected. Patients were followed up via clinical examination and questionnaires. Results Seventy-four patients were included and underwent endoscopy-assisted combined operations for the removal of 98 parotid stones. Of the 98 stones, 92(94%) stones were completely removed and 6(6%) were partially removed. At a mean follow-up of 47.1 ± 35 months, 65 of 74 patients (88%) achieved long-term success. Patients with stone incomplete removal were significantly more often to develop the recurrence of obstructive symptoms (p = 0.000) There were no cases of facial nerve injury or fistula formation. Gland function was preserved in 73 of 74 patients (99%). Conclusions The combined approach for parotid stones is a safe and gland-preserving alternative to parotidectomy. The techniques described here show high success rates and good long-term results, and they avoided the need for gland resection in >95% of cases.

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

To evaluate outcomes of in-office versus operating room (OR) sialendoscopy/sialolithotomy and to recognize the efficiency of outpatient salivary gland surgery with significant time and facility charge reductions.Case series with chart review.State hospital OR and ambulatory clinic.Retrospective review was performed of adult patients treated for inflammatory salivary diseases by a single surgeon from 2011 to 2016. The patients were divided into 2 groups based on procedure setting (office vs OR) and compared by various baseline features, including demographics, symptom onset and duration, stone size, symptomatic improvement, and recurrence. Patient time burden was compared via office procedure records and OR time charting from the electronic health record. Retrospective clinic and hospital charge sheets were tallied and similarly compared.The 2 cohorts (office, n = 111; OR, n = 96) were comparable in all demographics, including sialolith number and size (7.36 vs 6.69 mm, P = .45). Additional subgrouping was statistically similar. Both cohorts had similar postprocedure symptom improvement (97% vs 95.8%, P = .65) and recurrence rates (8.9% vs 14.5%, P = .22) independent of subgroup. Overall time burden for patients was 39 minutes in the office versus 277 minutes in the OR ( P ≤ .0001). Procedure and hospital charge data were tallied and compared (office, $719.21; OR, $13,956.14; P ≤ .0001).Bothcohorts were statistically similar in all features. There was significant reduction in patient time burden and health care charges with office-based procedures while maintaining similar symptom improvement and recurrence rates.

Objectives/Hypothesis The objectives of this study were to describe robot-assisted sialolithotomy with sialendoscopy (RASS) for the management of large palpable hilar submandibular gland (SMG) stones and analyze procedural success and lingual nerve damage following RASS in comparison to the combined transoral sialendoscopic approach. Study Design Retrospective chart review. Methods A retrospective chart review was performed on patients with large palpable hilar SMG stones managed with RASS following institutional review board approval. Large stones were defined as ≥5 mm, the upper limit that can be removed via sialendoscopy. Twenty-two patients between January 2012 and June 2014, with mean stone size of 12.3 mm, were identified. Data collected included symptoms of recurrence, postoperative lingual nerve function, and patient satisfaction at a mean follow-up of 14 months. Procedural success was defined as absence of symptom recurrence in conjunction with gland preservation. These measures were compared with the combined approach (CA) outcomes reported in the English literature. Results Procedural success was 100% (22/22) for our cohort. No patients reported symptoms of lingual nerve damage at follow-up, whereas four patients reported transient lingual nerve paresthesia (mean duration, 2.5 weeks). Mean patient satisfaction was 9.9 out of 10. Literature review identified 135 patients in the CA cohort. Procedural success rate for these patients was 75%, and lingual nerve damage was reported in 2% of patients. Conclusions Our study demonstrates the safety and efficacy of RASS in the management of large SMG sialoliths. We attribute this preliminary success of RASS to the enhanced visualization, magnification, and technical advantages of the procedure. Level of Evidence 4 Laryngoscope, 2015

Objectives/Hypothesis: To report our experience with management of giant salivary stones via a combined approach technique using salivary endoscopy (CA) and results of a review of current literature related to giant salivary stones. Study Design: Retrospective case series. Methods: An institutional review board-approved chart review was performed on patients managed with a CA to treat giant salivary stones (≥15 mm). In addition, we reviewed the English literature from 1942 to 2009. Results: Table 1 consists of 54 stones; 47 of which were identified during the review of literature and 7 from our case series. Of those 47 stones, 23 were hilar in location, 23 were glandular in location, and 1 stone was missing data. The gland preservation rate in the 47 reported stones was 57% (17/30). Among patients where gland resection was reported, the majority of the patients (12/13) had hilar glandular stones. Only one patient with a ductal stone had a gland resection. In our series, CA enabled a gland preservation rate of 86% (6/7). Among these patients, stone location was hilar glandular in six (86%) and ductal in one (14%). The mean size of stones from the literature review was 35 mm and from our series was 19 mm. Conclusions: Our review reflects current treatment recommendations for giant stones, i.e., transoral sialolithotomy for ductal stones and gland resection for hilar glandular stones. Our preliminary experience with CA for giant stones suggests improved gland preservation rates (86% vs. 57%) independent of stone location and with preservation of salivary function.
