Predictive factors for outcomes of sialoendoscopy

OBJECTIVES: We evaluated the epidemiological and clinical factors related to the complications and failure of sialoendoscopy. METHODS: This retrospective study analyzed the medical records of patients who underwent sialoendoscopy between 2010 and 2019. RESULTS: 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. CONCLUSION: Sialoendoscopy has uncommon and limited complications. Procedures in the submandibular gland and for sialolithiasis treatment were more likely to result in complications and recurrences. LEVEL OF EVIDENCE: 4.
