Predictive factors for outcomes of sialoendoscopy

Area of Science:

• Otolaryngology
• Minimally Invasive Surgery

Background:

• Sialoendoscopy is a minimally invasive technique for diagnosing and treating salivary gland disorders.
• Understanding factors influencing sialoendoscopy outcomes is crucial for improving patient care.

Purpose of the Study:

• To evaluate epidemiological and clinical factors associated with sialoendoscopy complications and failure.
• To identify specific salivary gland procedures and conditions linked to adverse outcomes.

Main Methods:

• Retrospective analysis of medical records from patients undergoing sialoendoscopy between 2010 and 2019.
• Data collected included patient demographics, gland treated, indication for procedure, and outcomes (complications, success rates).

Main Results:

• 174 sialoendoscopies were analyzed; 71.8% in women, 65.5% in the parotid gland.
• Most common complications: false path (4.59%) and restenosis (2.30%).
• Submandibular gland procedures had higher complication rates (3.43x) and lower success rates (86.7% vs. 91.2%) compared to parotid gland procedures. Sialolithiasis treatment showed the strongest association with complications and failure.

Conclusions:

• Sialoendoscopy demonstrates a low incidence of complications.
• Procedures involving the submandibular gland and treatment for sialolithiasis are associated with increased risk of complications and recurrence.
• Further research may focus on optimizing techniques for high-risk procedures.
