Hello, the sequelae of changing face may include insensitivity around cheeks or mouth. A few people will have this situation because the wound is swollen after operation and the facial sensory nerve is compressed. But don't worry, it usually takes two to four weeks, and the wound will recover after the swelling subsides. It is difficult to open your mouth because of swelling of masticatory muscles or swelling of wounds. It will recover slowly after swelling, and it will take about two weeks.
