Data Collection and statistical analysis:
The following data elements were collected for each patient in the cohort: basic demographics, social history, defect classification (partial vs. circumferential), previous treatment, ablative procedure, donor site morbidity, salivary bypass tube use, and functional outcomes. In addition, basic lab work results and nutritional status was also recorded for each patient. Also, skin paddle dimensions, recipient blood vessels, and venous coupler sizing was collected. Surgical outcomes and complications were documented for each patient both from the flap donor site and reconstructive site.
Lastly, speech and language pathology data were reviewed including voice outcomes, swallowing outcomes, enteral feeding usage, and tracheoesophageal puncture usage. Descriptive statistics were utilized after review of pertinent charts.
