Laryngeal electromyography (LEMG) demonstrates high diagnostic sensitivity and prognostic reliability in evaluating laryngeal neuromuscular disorders. We conducted a prospective case series of 37 patients presenting with voice and swallowing disorders to assess the diagnostic and therapeutic impact of LEMG. The study included vocal cord immobility (n = 15), presbyphonia (n = 7), spasmodic dysphonia (n = 5), puberphonia (n = 5), and dysphagia (n = 5). LEMG altered clinical management in 70.2% of cases by differentiating neurogenic from mechanical etiologies, predicting neural recovery, and guiding targeted interventions such as medialization or LEMG-guided botulinum toxin injection. Significant improvement in Voice Handicap Index scores was observed post-intervention (p < 0.001). Dysphagia patients demonstrated statistically significant improvement following cricopharyngeal botulinum injection (p = 0.012). This case series highlights the critical role of LEMG in refining diagnosis, guiding precision-based therapy, and optimizing patient-specific outcomes in contemporary laryngology practice.
