Introduction: Flap reconstructions in the head and neck area are a suitable method for covering larger soft tissue defects after tumor resections, predominantly of squamous cell carcinomas. Also for auricular reconstruction due to congenital malformation flaps can be used. Complications in the sequel are crucial for the outcome of the transplanted flap, including fistula formation, flap dehiscence, hematomas, seromas, infections and necrosis to total flap loss. Patients and methods: In this exploratory study, the outcome of all flap reconstructions between 2011 and 2016, conducted at the department of otolaryngology of the General Hospital Vienna, was analyzed retrospectively. There was a total of 164 flap surgeries on 139 patients. The collected pre- and postoperative data were presented by descriptive statistical methods. Subsequently, a possible association between the variables gender, age, tumor stage, flap localisation and complication of 'overall survival' as well as 'recurrence-free interval' was investigated; survival curves according to Kaplan-Meier were formed and compared with a log-rank test with significance level = 5% (two-sided). Results: Out of 164 flap surgeries 69 showed a complication-free postoperative course, after 95 flap surgeries (57.9%) complications occurred. Fistulas occurred most frequently in 20 (12.2%), dehiscences in 19 (11.6%) and complications at the donor site in 16 cases (9.8%). Total flap loss was only in 5 cases (3%), corresponding to a 97% success rate. A surgical flap revision had to be performed after a total of 47 surgeries (28,7%). No statistical significant correlation could be established between the variables gender, age, tumor stage, flap localisation, complication and the 'overall survival' as well as 'recurrence-free interval'. Conclusion: This retrospective study analyzes the outcome of both regional, pedicled and free flaps. The found success rate of 97% confirms and complements the success rate of most studies on flap reconstructions. Contrary to most research, higher tumor stages in this study were not associated with a shorter recurrence-free survival, possibly due to the limitation of the data set. The recommendation for further research is the implementation of larger, multi-center studies and to test other risk factors.
