Abstract

Objectives: Supracricoid partial laryngectomy (SCPL) is an oncologically sound alternative to total laryngectomy that results in long-term alterations in vocal function. Little is known about long-term improvements in dysphonia and the mechanism of vocal recovery is unclear due to the lack of a standardized rating tool: The Pattern, Degree, and Vibration (PDV) Scale. Methods: Data from 24 individuals were compared over 3 post-operative timepoints after SCPL: 3 to 11, 12 to 35, and over 35 months. Voice outcomes were assessed using the Voice Handicap Index (VHI) and the GRBAS scale. Laryngeal exams were deidentified and rated using a novel rating scheme developed using literature review and consensus panel discussions. Results: There were significant improvements in VHI scores, Grade, and Strain over time. There was an increase in the Degree of Closure and a decline in Mucosal Vibration across timepoints. Pattern of Movement (P) was associated with dysphonia Grade. Better Degree of Closure (D) was associated with lower VHI scores and better Grade and Roughness. Mucosal Vibration (V) was associated with reduced Breathiness and Strain but variable Roughness. Age, T-stage, radiation treatment, surgery type, and time to feeding-tube removal were also associated with voicing characteristics. Conclusions: There is evidence of improvement in several voice parameters over time after the first post-operative year. Various subcomponents of the new PDV rating scale were associated with voice outcomes. Its utility for research and clinical practice merits further investigation.
