Role of Video Laryngostroboscopy in Benign Disease of Larynx.

Benign disease of larynx frequently present with voice disorder. Observing the larynx with high resolution stroboscope and its mucosal wave pattern with greater precision aids in the better understanding of normal/abnormal anatomy and function, which forms the basis of designing treatment strategies.Videolaryngostroboscopy now a days is considered routinely used method of vocal fold examination and evaluation of patients with voice disorders. This valuable imaging tool can also be used to assess the outcomes of therapy of laryngeal diseases or functional result of phonosurgical procedures. Present study, videostroboscopic assessment of 81 cases of different benign vocal cord pathologies was done. Stroboscopic parameters like glottic closure, amplitude, vocal fold edge, symmetry, periodicity and mucosal wave pattern were studied and statistically significant relationship with different vocal pathologies were obtained.
