Four-duct ligation demonstrates a higher success rate for treating anterior drooling compared to two-duct ligation, with similar complication rates. This surgical intervention offers a safe and effective option for managing excessive salivation.
Area of Science:
- Otolaryngology
- Surgical Innovation
- Salivary Gland Disorders
Background:
- Anterior drooling is a common and debilitating condition with significant psychosocial and health impacts.
- Effective management strategies are crucial for improving patient quality of life.
Purpose of the Study:
- To systematically compare the efficacy and safety of 4-duct ligation versus 2-duct ligation for treating anterior drooling.
- To analyze success rates and complication profiles of each surgical approach.
Main Methods:
- A systematic review of CINAHL, PubMed, and Embase databases was performed.
- Studies analyzing success rates and complications of 2-duct or 4-duct ligation for anterior drooling were included.
Main Results:
- Four-duct ligation exhibited a significantly higher success rate (RD 0.47, RR 2.99) compared to 2-duct ligation.
- Complication rates were comparable or lower with 4-duct ligation. Infection was the most frequent complication for both methods.
Conclusions:
- Ductal ligation is a safe and effective surgical treatment for anterior drooling, characterized by high success and low morbidity.
- While 4-duct ligation shows promising results, definitive efficacy and safety comparisons between 2- and 4-duct ligations are limited by small sample sizes.
