The Effect of Initial Tracheoesophageal Voice Prosthesis Size on Postoperative Complications and Voice Outcomes.

OBJECTIVES: The optimal initial size of tracheoesophageal voice prosthesis (TEVP) for tracheoesophageal voice restoration (TEVR) remains unclear. As purported advantages exist favoring the placement of both 16F and 20F prostheses, this study compares complications and voicing outcomes after placement of 16 and 20 French (F) prostheses.

METHODS: All cases of TEVR at an academic medical center were retrospectively reviewed (2007-2013). Complications including dislodgement, leakage, infection, and granulation tissue were compared. Outcomes including frequency of prosthesis change, acquisition of speech, and time to fluent speech were compared.

RESULTS: Of 47 patients, 25 received 20F prostheses, and 22 received 16F. Postoperative complications were similar between groups, including leakage around the prosthesis (P = .373) and aspiration pneumonia (P = .670). There were no significant differences in timing of voicing or ability to achieve fluency. Although the 20F group appeared to undergo fewer prostheses changes per year (3.0 vs 5.3) and had a longer duration of use before first prosthesis change (76 vs 43 days), neither difference was found to be statistically significant.

CONCLUSION: Voice restoration was successfully achieved using either 16F or 20F prostheses. Prosthesis diameter did not significantly affect complications or voicing. Both prostheses may be placed with safety and efficacy, allowing the practitioner to choose based on the potential individual benefits of either device.
