Suture remnant-induced sialolithiasis and suppurative parotitis: A delayed complication following facial thread lifting.

Facial thread lifting is a popular, minimally invasive procedure for facial rejuvenation. While most complications are mild and self-limiting, severe adverse events may occur rarely. Injury to the parotid gland or its ducts represents a serious complication, particularly when leading to delayed sequelae such as sialolithiasis. We present the case of a 45‑year‑old female who developed acute suppurative parotitis and sialolithiasis three years after facial thread lifting. The patient received antibiotic therapy followed by surgical removal of the calculi. Intraoperatively, suture remnants were identified within the calculi. The patient recovered well postoperatively. This case highlights the risk of parotid duct injury and secondary chronic sialolithiasis following thread lifting, which may predispose patients to suppurative parotitis. Clinicians should be aware of this rare but significant delayed complication. Precise surgical technique and strict adherence to anatomical planes are crucial to prevent such adverse events.
