Lacerations are extremely common and Mr Callan repairs many each year. Lacerations can be caused by running into blunt stationary objects or by sharp objects such as glass or a knife. Your general practitioner is your best guide as to whether you will need a plastic surgeon. Plastic surgeons have specific skills to assess certain injuries to ensure there is no deeper damage and then to repair those injuries accurately to give you the best possible result and minimise scarring.
