This case report details sialolithiasis (salivary stones) in an accessory submandibular duct, a rare finding diagnosed via sialendoscopy. Successful treatment involved endoscopic and intraoral removal of these stones.
Area of Science:
- Otolaryngology
- Oral and Maxillofacial Surgery
- Sialology
Background:
- Recurrent sialadenitis can significantly impact patient quality of life.
- Submandibular sialolithiasis is a common cause of sialadenitis, typically involving the main duct.
Observation:
- Computed tomography suggested extensive sialolithiasis in the main right submandibular duct.
- Sialendoscopy revealed a normal main duct but identified an accessory duct with significant sialolithiasis.
Findings:
- This is the first reported case of sialolithiasis within an accessory submandibular duct diagnosed during sialendoscopy.
- The condition was successfully treated using a combined endoscopic and intraoral approach.
Implications:
- Sialendoscopy is crucial for identifying accessory salivary ducts and their pathologies.
- Preoperative imaging may aid in planning surgical approaches for complex sialolithiasis cases.
