# Predictive factors for outcomes of sialoendoscopy

## TL;DR

Sialoendoscopy is a minimally invasive treatment for salivary gland diseases with high success rates and few complications.

## Contribution

This study identifies predictive factors for complications and failure in sialoendoscopy procedures.

## Key findings

- Submandibular gland procedures had higher complication rates compared to parotid gland procedures.
- Sialolithiasis treatment was most strongly associated with complications and failure.
- Sialoendoscopy overall has uncommon and limited complications.

Chronic sialoadenitis is mainly treated with surgical procedures.

Sialoadenectomies may result in aesthetic defects and complications.

Sialoendoscopy is an effective treatment for major salivary gland duct diseases.

Sialoendoscopy boasts minimal complications and high success rates.

We evaluated the epidemiological and clinical factors related to the complications and failure of sialoendoscopy.

This retrospective study analyzed the medical records of patients who underwent sialoendoscopy between 2010 and 2019.

Of the 174 sialoendoscopies analyzed, 125 (71.8%) were performed in women, and 114 (65.5%), in the parotid gland. The most prevalent complications described were false path (4.59%) and restenosis (2.30%). Complications in the submandibular gland were 3.43 times more common than those in the parotid gland and procedures in that gland were less successful (86.7% vs. 91.2%). Sialolithiasis treatment was most strongly associated with complications and failure then the other groups.

Sialoendoscopy has uncommon and limited complications. Procedures in the submandibular gland and for sialolithiasis treatment were more likely to result in complications and recurrences.
