Treatment and reconstruction of oral scar contracture, is always a challenging procedure to restore structure and functions of the oral cavity. We present a case of a patient with limited mouth opening who sustained extensive oral scar contracture with complete adhesion of tongue to floor of mouth following ingestion of caustic soda without his knowledge 4 years back. We performed a surgical release of the scar contractures from buccal mucosa on both sides, along with a release of the tongue from the floor of the mouth, followed by reconstruction of all sites using split skin grafts. Adequate mouth opening and tongue movement was achieved. There was a follow up period of 1 month with excellent mouth opening and tongue function.
