My husband had a full beard before his neck disection. He didn't want them shaving or trimming it so he shaved it off and went down to a gotee before surgery. He was fitted for the mask with the gotee. A few weeks into radiation, all his facial hair fell out. His gotee was clipped pretty close to start with so there really wasn't a "fit issue" once the whiskers fell out.
