Longitudinal Voice Outcomes and Neoglottic Function After Supracricoid Partial Laryngectomy: The Development of a New Scale.

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.
