Facial atrophy following accidental subcutaneous extrusion of sodium hypochlorite.

Facial atrophy of the buccal fat pad following inadvertent subcutaneous extrusion of sodium hypochlorite is very rare. It is a complication which leaves the patient with a defect which is very difficult to treat. We present the case of a 46-year-old lady who presented with almost complete unilateral atrophy of the buccal fat pad. She has undergone multiple surgeries over the past two years. We highlight the precautions that must be taken to prevent such a complication and the difficulties in rehabilitating such a patient.
