Summary
The Transoral Stensen's Duct Approach (TSDA) is effective for parotid gland duct stones when other methods fail. This safe, minimally invasive technique offers good results for anterior stones, potentially avoiding surgery.
Area of Science:
- Otolaryngology
- Minimally Invasive Surgery
- Endourology
Background:
- Parotid gland duct lithiasis often requires minimally invasive treatments like sialendoscopy and lithotripsy.
- These methods may not resolve all duct obstructions, necessitating alternative approaches.
Purpose of the Study:
- To evaluate the efficacy and safety of the Transoral Stensen's Duct Approach (TSDA) for parotid duct lithiasis.
- To assess TSDA outcomes in patients with prior failed sialendoscopy or lithotripsy treatments.
Main Methods:
- Retrospective study of 22 patients with 28 parotid duct stones treated via TSDA (2006-2013).
- Inclusion criteria: failed sialendoscopy and/or lithotripsy for parotid duct obstruction.
- Evaluation of pain, swelling, and infection over a mean 47.4-month follow-up.
Main Results:
- TSDA achieved an 87.5% immediate success rate for anterior parotid duct stones.
- Low morbidity observed, including transient facial nerve palsy and post-operative stenosis.
- Effectiveness for posterior stones, stenosis, or megaducts was limited.
Conclusions:
- TSDA is a safe and straightforward technique for anterior parotid duct lithiasis refractory to other treatments.
- It can be a valuable alternative to external surgery or parotidectomy.
- While having limitations for posterior obstructions, TSDA is a useful adjunct in the management of parotid duct stones.
