Current Practices in Microvascular Reconstruction by Oral and Maxillofacial Surgeons

Purpose Microvascular free tissue transfer (MFTT) is a reliable reconstructive option with variation in perioperative care and a general lack of clinical practice guidelines. Oral and maxillofacial surgeons’ (OMSs) current MFTT perioperative practices in the United States have not been described. This study describes these practices including surgeon practice environment, operative practices, perioperative management, and success. Methods The study design is cross sectional. The sample is composed of OMSs who completed an Oral/Head and Neck Oncologic and Microvascular Surgery Fellowship prior to 2018 in the United States. Data were collected by means of a survey of the study sample. Descriptive statistics were reported. Results Forty surgeons responded to the survey for a response rate of 33.9%. Respondents were 97.5% (n = 39) male and worked in private (n = 8), combination (n = 10), and academic practices (n = 23). Surgeons in private and academic practice performed an average of 23.3 (SD 13.9) and 48.6 (SD 28.6) flaps per year respectively. 88.2% of surgeons operated with a 2-team approach. Immediate dental implants were placed in osteocutaneous free flaps by 28.6% (n = 2) of private practice surgeons and 70% (n = 14) of academic surgeons. Postoperatively, most patients went to an intensive care unit (ICU) (82.7%, average duration 2.6 days). Anticoagulation or antiplatelet medications were routinely used with the most common choice being aspirin (77.4%, n = 24). Antibiotics were universally administered, often for 3 days or longer (74.2%, n = 23). Self-reported success rates were 95.3% (SD 4.1) and 96.0% (SD 1.7) in private and academic settings respectively. Conclusion This is the first report of practice trends by microvascular OMSs in the United States. The results of this study suggest that there is variation in MFTT operative and perioperative practices by individual surgeons and practice environment with minimal variation in self-reported success rates.
