Brief summary

The primary study goal is to evaluate the histological characteristic of Silk Voice to evaluate the potential for Silk Voice to deliver long-term results to patients.

Detailed description

The primary study goal is to evaluate the histological characteristic of Silk Voice at a surrogate implantation site to evaluate the potential for Silk Voice to deliver long-term results to patients. Information obtained from this study will help clinician determine Silk Voice's treatment duration and whether Silk Voice is appropriate for their patient.
