CHAPTER 2 Objective and subjective voice outcomes after total laryngectomy: a systematic review Abstract Background: Esophageal speech (ES), tracheoesophageal speech (TES) and/or electrolarynx speech (ELS) are three speech rehabilitation methods which are commonly provided after total laryngectomy (TL). Methods: A systematic review of the literature was conducted to evaluate comparative acoustic, perceptual, and patient-reported outcomes for ES, TES, ELS and healthy speakers. Results: Twenty-six articles could be included. In most studies, methodolog- ical quality was low. It is likely that an inclusion bias exists, many studies only included exceptional speakers. Significant better outcomes are reported for TES compared to ES for the acoustic parameters, fundamental frequency, maximum phonation time and intensity. Perceptually, TES is rated with a significant better voice quality and intelligibility than ES and ELS. None of the speech rehabilitation groups reported clearly better outcomes in patient- reported outcomes. 0 Appeared as: van Sluis, K.E., van der Molen, L., van Son, R.J.J.H., Hilgers, F.J.M., Bhairosing, P.A., van den Brekel, M.W.M. “Objective and subjective voice outcomes: a sys- tematic review.” European Archives of Oto-Rhino-Laryngoly 275,1: 11-26, 2018.
