<p>In our case, we report a previously unreported complication of a thread lift procedure in the jowl region. This complication was caused by damage to the glossopharyngeal nerve through compression. The case also illustrates the diagnostic and therapeutic aspects of iatrogenic injury to the glossopharyngeal nerve. The widespread use of thread lift in aesthetic medicine has increased the variety and frequency of complications. The thread lift procedure is an blind intervention in which critical anatomical structures are not directly visualised. Therefore, the risk of damage to various structures is also high. Damage to the nerves in the application area is manifested by specific symptoms such as sensory deficits, pain, swallowing impairment, and autonomic dysfunction. We describe the diagnosis and treatment of a glossopharyngeal nerve injury caused by compression of the nerve trunk following a facial thread lift procedure.</p>
