Abstract
The purpose of this study was to investigate the causes of dysphagia after cervical surgery using laryngeal electromyography (LEMG), and the effect of laryngeal neuropathy on the severity of dysphagia. Seventeen patients with dysphagia evident after cervical surgery were included. Video fluoroscopic swallow study (VFSS) parameters evaluated included the volume of residue in the vallecular pouch and the pyriform sinus, the Rosenbek penetration-aspiration scale (PAS), and the swallowing function scoring system (SFSS). By VFSS findings, patients were classified into a mild or severe dysphagia group. Nine of 17 patients showed voice change. SFSS scores were 0 in 2 patients, 3 in 1 patient, 4 in 1 patient, 5 in 1 patient, and 6 in 12 patients. PAS scores were 1 in 8 patients, 2 in 5 patients, 7 in 3 patients, and 8 in 1 patient. Laryngeal neuropathy was evident in seven patients (41.2%). Of these, all patients exhibited recurrent laryngeal neuropathy and 28.6% had superior laryngeal neuropathy. When we evaluated LEMG findings with respect to the severity of dysphagia, the severe dysphagia group showed significant association with the presence of laryngeal neuropathy (p = 0.006). Although the level of residue in the vallecular pouch was not associated with the presence of laryngeal neuropathy (p = 0.442), the amount of residue in the pyriform sinus did show a significant association (p = 0.020).
