The Long-term Indwelling Tracheoesophageal Prosthesis for Alaryngeal Voice Rehabilitation

Abstract

The indwelling tracheoesophageal voice prosthesis offers patients all the advantages of tracheoesophageal speech rehabilitation after laryngectomy without the inconvenience of frequent prosthesis changes. With careful attention to the details of fitting and care, it can be worn by the majority of patients successfully.

A Decade of Postlaryngectomy Vocal Rehabilitation in 318 Patients

“…In addition, as also mentioned by others, the last valve has to be censored, since the exact lifetime of that valve is not yet known, ie, the valve has not failed at the time of analysis. 17 In our study, the mean value (163 days) is comparable to that reported by others (range, 148-311 days) 18,19,23,24,26 and to the 141 days reported earlier. 25 The median value of 89 days is lower than the values reported by others (101 and 137 days), 17,33 and probably is influenced by the shorter device lifetime of Provox2, which has not yet been used by the other authors.…”

“…In comparison to other studies, the mean indwelling time of both groups was longer than in reports using solely the Provox 2 prostheses (69 days and 96 days) but shorter than in studies using only the Provox 1 or both the Provox 1 and Provox 2 prostheses (between 141 days and 311 days), [22][23][24][25][26]34,35 mainly due to the generally longer device lifetime of the Provox 1 prosthesis. [23][24][25] The median indwelling time observed in patients after laryngectomy in this study was similar to results published recently by other authors (92 days and 3.7 months).…”

Speech rehabilitation after total laryngectomy: long-term results with indwelling voice prosthesis Blom-Singer®

“…The habitual life of the prosthesis used in this study was 6.43 months and it exceeded the average of 7 weeks of the short-term prosthesis 4 . The financial aspects of the indwelling device are also comparable to short-term devices 4 . These prostheses are not completely free from maintenance.…”
