Current practice trends in microvascular free flap reconstruction by fellowship-trained otolaryngologists.

Purpose: In the field of head and neck microvascular surgery, there are currently no clear, universally accepted recommendations on the intraoperative, preoperative, and postoperative management of these patients.

Materials And Methods: A 23-question cross-sectional survey was distributed to otolaryngologists who perform microvascular reconstruction. Information about practice setting, fellowship training background, intraoperative practice, postoperative practice, and surgical complications were analyzed.

Results: Complete survey responses were received from 102 (32.8% response rate) of surveyed otolaryngologists who perform microvascular surgery. A great degree of variability was noted in intraoperative and postoperative care of free flap patients. Overall, self-reported free flap survival-rates were relatively high, despite the variability in practice, with the majority of surgeons (74%) reporting flap survival rate of 96-100%. Complication rates requiring return to the operating room were low; all respondents reported <20% overall complications with <10% re-operation rates due to vascular complications.

Conclusion: An increasing number of microvascular-trained otolaryngologists are performing free flaps. Self-reported free flap survival rates are high and complication rates are low, despite significant variability in intraoperative and postoperative practices among otolaryngologists performing microvascular flap reconstruction. By identifying these differences among surgeons, we hope to provide the impetus for further academic dialog and prospective trials.
