title: Surgical resection of cervical schwannoma and paraganglioma: Speech and swallowing outcomes.
abstract: We conducted a retrospective study (1999 to 2009) at our tertiary care institution to evaluate speech and swallowing outcomes after the resection of cervical schwannoma or paraganglioma. Of 6 patients treated for schwannoma, 5 (83.3%) had immediate dysphonia and dysphagia. All patients with deficits received primary reinnervation (n = 2) or subsequent medialization laryngoplasty (n = 3). At 6 months, 4 patients (66.6%) still had dysphonia and dysphagia. At final follow-up (median: 10 months; range: 8 to 12 months), 4 patients (66.7%) had dysphonia and 2 (33.3%) had dysphagia. Of 10 patients treated for paraganglioma, 6 (60.0%) had immediate dysphonia and dysphagia. Four patients received subsequent medialization laryngoplasty; none had primary reinnervation. At 6 months, 3 (30%) still had dysphonia and dysphagia. At final follow-up (median: 15.5 months; range: 1.25 to 48 months), 2 (20.0%) had dysphonia and dysphagia. All patients with deficits received speech and swallowing therapy. We conclude that cervical schwannoma and paraganglioma resection was associated with high rates of immediate postoperative dysphonia and dysphagia. Schwannoma had higher initial rates and poorer recovery. Primary and/or subsequent laryngeal procedures combined with therapy led to symptom resolution in some patients.
