Exploring Salivary Gland Complications: Case of Acute Parotitis After Botulinum Toxin Injection for Bruxism
Israel: Recent reports have emerged highlighting botulinum toxin-induced parotitis as a significant postoperative complication following masseter muscle injections. This unexpected adverse effect has raised concerns among practitioners in aesthetic medicine and dentistry, necessitating increased awareness and caution during procedures.
A recent case study has described a case of acute parotitis in a 60-year-old female following Botulinum toxin (BTX) injections to the masseter muscle (to treat bruxism). The botulinum toxin also impacted the parotid gland and facial nerve leading to reduced saliva production and weakness in the corresponding facial muscles.
The case published in the Journal of Oral and Maxillofacial Surgery highlights the possible salivary gland complications after BTX injection into the masticatory muscles.
The case concerns a 60-year-old female who presented to the emergency room (ER) with complaints of swelling and pain in the right side of the face, accompanied by xerostomia, which was initiated a week before her ER visit. The patient indicated that she received a botulinum toxin injection in the masseter muscle three weeks before she visited the ER for her known bruxism. She reported experiencing mild muscle weakness at the right commissure, which had improved a few days before her arrival.
