Why don't you research the reason, why physicians wear masks, why surgeons wear masks during surgery. Maybe you could even come back with the results of studies that have measured infection rates of surgeons with and without masks?
Thats not how this works. You told me there was a reason other than pandemic virus why practitioners aren’t wearing masks. The onus is on you to prove your assertion.
