He offers operative and office-based laser for papilloma, utilizing the Blue Light laser, which allows for precise excision of papilloma while preserving underlying vocal function. Dr. Best is also a pioneer in the adjuvant use of bevacizumab for RRP, helping many patients break the cycle of repeated surgeries. The Best Laboratory studies RRP and the development of novel immunotherapies to target the underlying viral infection. This research is conducted in collaboration with the head and neck cancer and cervical cancer research groups at Johns Hopkins, which also study human papillomavirus-related diseases. In addition, Johns Hopkins is a site for ongoing clinical trials in DNA immunotherapy, the goal of which is to eliminate the causative viral infection that leads to RRP.
