The aim of the study was comparison of voice and life quality after microdirect laryngoscopy in three patient histopathological categories: benign, precancerous, and malignant glottic lesions. A totalnof 137 patients treated with microdirect laryngoscopy were included in the study. Each patient was evaluated with a multidimensional protocol before and 3, 6, and 12 months after treatment. Final 1-year evaluations were achieved in 74.5% (102). The assessment included laryngovideostroboscopy (LVS), perceptual (GRBAS) grading, aerodynamic measures including maximum phonation time and phonation quotient and acoustic measurements (Kay Elemetrics Multi-Speech program), Voice Handicap Index (VHI), Voice-Related Quality of Life questionnaire; and World Health Organization Quality of Life Scale-Brief Version (WHOQoL-BREF). An improvement in mean value of LVS ratings was obtained in all three groups; however, only in benign lesion group was it consistently statistically significant for each time period (P < 0.001). Perceptual evaluation revealed significant improvement of G, R, and B parameters in benign lesions for each time period. In malignant neoplasms R and B parameters improved 3 and 6 months post microsurgery. In patients with benign lesions the maximum phonation time increased, but the improvement was significant only after 3 months. The acoustic parameters improved in all three groups. VHI significantly improved in patients with benign lesions after 3 and 12 months. VHI in the malignant neoplasm group significantly worsened on the first follow-up visit. Considering quality of life (QoL) results, only in patients with benign lesions was there a significant improvement in overall assessment of their QoL and general health.
