Laryngeal nerve damage is a serious complication of thyroidectomy. We present a closed-loop audit of pre-operative fibreoptic vocal cord checks to determine whether implementation of a rapid-access otolaryngology voice assessment improves the rate of pre-operative checks. Data were collected retrospectively from thyroidectomies performed within the Brighton and Sussex University Hospitals Trust over one year. Data were analysed, a rapid-access otolaryngology voice assessment service instigated, data disseminated to both ENT and general surgery departments, and a re-audit performed over the subsequent six-month period. Pre-operative vocal cord check rate increased from 87.6% to 92.3%. Post-operative documentation of voice increased from 68.5% to 96.1%. The voice assessment service improved the trust's preoperative assessment of vocal cords by facilitating easy access to flexible nasoendoscopy.
