This study will determine if high thyroid surgical volume compared to intermediate thyroid surgical volume in an individual surgical practice can reduce rates of transient and permanent vocal fold immobility.
Single surgeon, single institutional retrospective review comparing vocal fold immobility when a mean of 32 recurrent laryngeal nerves were dissected per year (Group A) versus when 109 recurrent laryngeal nerves were dissected per year (group B). Pre and post-operative fiberoptic laryngoscopy and nerve integrity monitoring were used in both groups.
The rate of transient and permanent vocal fold immobility in Group A was 3.7% and 1.6%. The rate of transient and permanent vocal fold immobility in Group B was 0% and 0.9%.
High thyroid surgical volume compared to intermediate thyroid surgical volume resulted in a significant improvement in transient vocal fold immobility with a trend toward improvement in permanent vocal fold immobility.
