“…This is similar to previous reports in the literature depending on the rating scale used, the extent of surgery and the patient-related comorbidities [10][11][12] . The low tone of speech was a consistent source of discontent amongst valve users [4] .…”

Background: This study aimed to assess valved speech and related issues in total laryngectomy patients with the help of the validated Voice Prosthesis Questionnaire (VPQ). Patients and Methods: We identified 61 patients who had undergone a surgical voice restoration with a valve following total laryngectomy and who were sent the VPQ by mail. Results: Fifty-one patients (37 males) completed the questionnaire giving a response rate of 83.6%. Fifty-three percent of the patients (n = 27) were fully aware of the dimensions of their valve including the length and diameter, whilst 25% (n = 13) were aware of only one of the two. There was a strong correlation between the patient’s perception of tone and their gender with the tone scores significantly lower in women as compared to men (Mann-Whitney test, p = 0.04). Ten patients (19.6%) had had leakage-related issues during the previous 7 days. Conclusions: This questionnaire provided a significant amount of valuable data. Based on our experience, we recommend the VPQ for prospective use in the serial monitoring and audit of total laryngectomy patients.

“…Device‐life assessment has received quite a bit of attention over the last two decades of indwelling voice prosthesis research, but ever since the discovery that biofilm formation with its most visible end result, the growth of Candida species,9 it is obvious that silicone rubber voice prostheses remain limited in their functional survival. Worldwide there are considerable differences in device life published, with the shortest ones in Western Europe (median, 3 months; mean, 5–6 months), and the longest in Mediterranean countries and India, with the United States in between (mean, 9–12 months) 6, 10–15. Most likely, these differences are caused by differences in biofilm buildup, which have been hypothesized to have a relation with differences in diet in these areas 16, 17.…”

“…Numerous studies of both TEP procedures have been reported with success rate that ranges from 30 to 93% [4] If we look in the Indian contingent perspective, the first account of this procedure is available from Hazarika et al in 1990 [5], since then many centers have taken this work but only few have reported their experiences [6][7][8][9][10][11].…”

Author presents in this study 160 patients who underwent tracheoesophageal puncture (TEP) for voice rehabilitation after laryngectomy. This study represents authors experience in Indian perspective with regards to technique, timing of surgery, i.e., primary or secondary, effect of socioeconomic condition of the patients. Author also narrated complications secondary to the TEP voice and prosthesis, during long follow-up of 15 years. The primary and secondary TEP were compared in patients having good socio-economical status with that of relatively poor status patients. As compared to the western literature, this Indian study showed significant differences in success rate of achieving good TEP voice production and also continuing use of TEP voice. Author observed that despite, entirely different socio economic condition and lack of proper follow-up, the secondary TEP done after complete evaluation of the patient yields much better sustained results for successful voice acquisition and continuation of the use of acquired voice. Author has described in details about the surgical procedures for secondary TEP; the prosthesis, care of prosthesis, problems due to TEP and prosthesis and the ways to rectify these problems.
