(P-value for VHI was 0.004 and that of GRBAS was 0.00). On acoustic analysis, mean pre-operative habitual fundamental frequency (FO), jitter % and shimmer % was 245.82 Hz, 0.21 and 2.34, respectively, whereas post-operative mean was 140.78 Hz (P=0.00), 0.19 (P=0.04) and 1.52 (P=0.00), respectively.Conclusion: The mainstay of treatment of puberphonia is voice therapy. Thyroplasty provides a suitable management option in those cases who fail to respond by voice therapy./p
