“…The parotid glands are the largest source of stimulated saliva, and even children who are not fed orally may kinetically stimulate the glands with fingers and other objects. Other treatments for sialorrhea typically avoid the parotid gland directly due to the risk of nerve injury, and this has previously been a shortcoming in sialorrhea management [30]. The low rate of nerve injury in our safety cohort is encouraging and refining this technique is important for the future management of sialorrhea.…”

Background Sialorrhea is common in children with neurological disorders and leads to social isolation, aspiration pneumonia and increased caregiver burden. Sialorrhea management includes anticholinergic medications and a variety of surgeries, but these are limited by side effects, recurrence and risks. Objective We present our method of salivary gland ablation, an interventional radiology treatment for sialorrhea, and report safety and efficacy data from pediatric patients who underwent salivary gland ablation. Materials and methods Salivary gland ablation uses image-guided sotradecol and ethanol dual-drug injection into the salivary glands. Submandibular and sublingual glands are injected percutaneously using ultrasound. Parotid glands are injected retrograde through Stensen ducts using fluoroscopy. We conducted a retrospective review of the medical records of patients who underwent salivary gland ablation at our institution between 2005 and 2019. Pre-and post-procedure Drooling Frequency and Drooling Severity (DFDS) scale scores were compared and caregiver satisfaction was assessed. We devised two cohorts, one to study patient safety and a subcohort to study clinical efficacy using DFDS scores. Results One hundred and seventy salivary gland ablation procedures were performed in the 99 patients comprising the safety cohort. Of the procedures, 88.8% resulted in no or minimal complications. Respiratory difficulty, temporary nerve palsy and infection represent the majority of the 11.2% of patients who experienced periprocedural complications. There were no complications resulting in permanent sequelae. Twenty-seven patients met our inclusion criteria for the efficacy subcohort with a mean follow-up time of 5.4 years. DFDS at follow-up decreased from a median score of nine to a seven post-procedure (P=0.000018). The proportion of caregivers who were satisfied with the procedure increased as more glands were ablated, which suggests a causal link between the number of glands ablated and the outcome. Conclusion Salivary gland ablation is a safe and effective procedure with the potential for permanent decrease in symptoms related to sialorrhea.

“…This method, known as NOTES, is technically feasible and provides a good surgical field, and thus it is thought to be applicable to patients with TGDCs. In previous studies, we reported the safe excision of dermoid cysts, TGDCs, ectopic thyroid tissue, and thyroid isthmus mass through an endoscope‐assisted transoral approach with a frenotomy incision . This showed that a transoral approach was technically feasible, which allowed us to reach the thyroid gland without major tissue damage or bleeding.…”

“…The accessory parotid gland is a salivary tissue separated from the main parotid gland. It is located between the skin and the masseter muscle, in front of Stensen's duct . If a patient presents with a midcheek mass, an accessory parotid gland mass should be suspected .…”

Objective: Transoral surgery is gaining favor because it has the advantage of leaving no scar after surgery. The aim of this study was to evaluate the technical feasibility and safety of endoscope-assisted transoral accessory parotid mass excision.Study Design: Multicenter, prospective, observational study.Methods: This study was designed as a 7-year, prospective, multicenter evaluation of endoscope-assisted transoral accessory parotid mass excision. Clinical outcomes and complications related to the procedures were evaluated in patients.Results: Twenty patients underwent endoscope-assisted transoral accessory parotid mass excisions, and 22 patients underwent conventional parotidectomy approach excisions. There was no significant difference with respect to overall demographic characteristics between the groups. However, the operation times were shorter in the transoral approach group (P = 0.001), and cosmetic satisfaction was much better in the transoral group (P < 0.001).Conclusion: Endoscope-assisted transoral accessory parotid mass excision is a potentially safe and effective procedure with excellent outcomes.
