Minimally-invasive definitive treatment of recurrent sialadenitis due to obstructive sialolithiasis - a case report.

Introduction: Salivary gland lithiasis is one of the most frequent causes of sialadenitis. We report the case of a patient who presented multiple episodes of subangulomandibular tumefaction, until salivary lithiasis was finally identified as the underlying condition and resolved through a minimally invasive approach. Case report: A 43-year-old male patient presented with a history of 12 episodes of recurring one-sided subangulomandibular tumefaction over the course of the past 3 years. A computed tomography of the head and neck revealed a large calculus on Wharton's duct and right lithiasic submaxillitis. Non-steroidal anti-inflammatory treatment and antibiotic treatment was administered, and after the complete resolution of the acute process, we performed a sialendoscopically-assisted sialolithotomy with complete removal of the calculus. Following the procedure, the patient was discharged on the same day, clinically well, and displayed no further recurrences over a follow-up duration of 12 months. Conclusions: The case we have reported highlights the importance of performing a correct differential diagnosis and of determining the underlying cause of recurrent sialadenitis, in order to ensure the most adequate therapeutic and, when warranted, minimally-invasive surgical management for definitive treatment.
