Summary
Extracorporeal shock wave lithotripsy (ESWL) effectively treats salivary stones, particularly smaller ones within glands. While ESWL aided stone fragmentation and excretion in most patients, some required additional procedures.
Area of Science:
- Urology
- Otolaryngology
- Biomedical Engineering
Context:
- Sialolithiasis, or salivary stones, affects salivary gland function and patient quality of life.
- Traditional treatments for sialolithiasis can be invasive, often requiring surgical gland removal.
- Extracorporeal shock wave lithotripsy (ESWL) offers a non-invasive therapeutic option.
Purpose:
- To evaluate the efficacy and safety of ESWL in treating patients with sialolithiasis.
- To determine the optimal indications for ESWL in salivary stone management.
- To compare ESWL outcomes with traditional surgical interventions.
Summary:
- ESWL was performed on 11 patients with sialolithiasis, with varying degrees of success.
- Fragmented calculi were excreted in 7 patients; 4 required additional intraoral ductotomy for complete stone removal.
- ESWL was ineffective for large (20 mm) or purely intraducted stones.
- No severe complications were observed during or after ESWL treatment.
Impact:
- ESWL is a beneficial treatment for salivary stones, especially intraglandular and transitional zone types smaller than 10 mm.
- ESWL can potentially avoid the need for submandibular glandectomy in select cases.
- Further research may refine ESWL protocols for improved outcomes in complex sialolithiasis cases.
