Postoperative Dysphagia Management in Hemifacial Spasm: A Case Report of Combined Catheter Balloon and Neuromuscular Stimulation

Abstract Background: Hemifacial spasm is a frequently encountered cranial nerve disorder caused by vascular compression, and microvascular decompression is considered the criterion standard treatment, particularly for cases resistant to pharmacological or botulinum toxin therapy. Although microvascular decompression is generally safe, it carries the risk of cranial nerve complications. Glossopharyngeal and vagus nerve dysfunction can result in cricopharyngeal dysfunction, leading to significant postoperative dysphagia characterized by poor upper esophageal sphincter (UES) opening, aspiration, and pharyngeal residue. Early and effective rehabilitation is
