Wiskirska-Woźnica B, Leszczyńska M, Swidziński, Czerniejewska H, Jackowska J, Witold S. Voice estimation in patients after reconstructive subtotal laryngectomy. Head Neck Oncol. 2011 Oct 26;3:46.

Conclusions The perceptual voice estimation revealed a good phonation result in only 3 cases after using surgery with the Calearo method as well as the best results of MPT. The VHI reflected severe voice handicap in 2 patients (26 to 40 points). No statistically significant differences were observed between the values of the acoustic parameters in MDVP analysis after following operation -CHEP, Calearo, Sedlacek.
