ObjectiveDetermine the effectiveness of calcium hydroxylapatite paste in vocal rehabilitation in routine clinical practice.MethodsRetrospective series of adult patients undergoing calcium hydroxylapatite paste injection for vocal fold rehabilitiation over a 3-year period. Outcomes include change in Voice Handicap Index (VHI) scores, procedure-related complications, and need for follow-up vocal procedures.ResultsA total of 23 patients with an average age of 65 years underwent vocal fold rehabilitation with calcium hydroxylapatite injection performed by operative endoscopy.

Following injection, 17 patients (74%) had improvement in voice as measured by VHI, 4 had worsening of voice, and 2 were essectially unchanged from baseline. The mean VHI scores improved from 66 (S.D. 4.4) to 35 (S.D. 4.5) after a mean follow-up time of...
