2.2 | Outcome measurement
Clinical factors were compared between the two groups, and outcomes were analyzed according to suture time and complication. Suture time was measured during closure of oral/oropharyngeal defects. Suture times were compared according to site. Complications were categorized by wound dehiscence and foreign body sensation due to suture material at more than two weeks after surgery. The Mann–Whitney test was used to compare continuous variables, and categorical variables were analyzed with Fisher’s exact test. P-value < 0.05 was considered statistically significant. Statistical analyses were performed using SPSS for Windows ver. 20.0 (SPSS Inc., Chicago, IL, USA).
