Research Interest Summary

Laryngopharyngeal Reflux, Laryngeal Electromyography, Vocal fold paralysis, Surgical ergonomics, Quality of life and dysphagia

Research Interests

Dr. Smith's primary area of research is the treatment of vocal fold paralysis, utilizing laryngeal EMG to guide customized patient treatment, as well as vocal fold augmentation.  Dysphagia (difficulty swallowing) often results in poor quality of life for affected patients.  Recent research efforts are building around improving patients quality of life in dysphagia, especially after head and neck cancer treatment.  Surgical ergonomics has been a passion of Dr. Smith's for years, to optimize surgeon positioning, to thus reduce musculoskeletal injury.
