We compared the voice outcomes after cricotracheal resection (CTR) and airway dilation in adult women.


We performed long-term comprehensive voice assessments in 23 adult women treated for laryngotracheal stenosis, including acoustic and perceptual measurements of voice, videostroboscopy, the Voice Handicap Index, and an open-ended subjective questionnaire.


Voice measures were abnormal in both groups. Objective pitch and loudness measurements were significantly more impaired after CTR than after dilation. Perceptual ratings of voice were worse after CTR than after dilation, particularly with regard to breathiness, pitch, and loudness. The CTR group was more likely to report a voice disorder, reported significantly more voice symptoms, and had higher voice handicap scores. Videostroboscopy was frequently abnormal in both groups, with more evidence of vocal hyperfunction after CTR. Self-ratings of breathing and swallowing were generally high in both groups, but voice satisfaction was rated lower after CTR.


Voice was more significantly negatively impacted by CTR than by dilation. Surprisingly, many individuals in both groups reported improvements--a finding that possibly highlights the impact of laryngotracheal stenosis on airflow and vocal function before surgery. The importance of patient selection and preoperative counseling is emphasized, along with the potential need for voice therapy.
