This new proposed maxillofacial categorization is based on the scoring of two groups: Group I and Group II. The information obtained in Group I permits evaluation of (1) life-threatening injuries; (2) maxillofacial etiological factors producing life-threatening injuries; and (3) other organ or anatomic areas that may also have been injured. This information permits a fast and correct categorization of the patient before hospitalization and helps achieve transportation to an adequate hospital in an adequate amount of time and adequate treatment. Using the score obtained for Group II categorization, the functional and aesthetic severity of soft tissues (skin, mucosa, scalp), skeletal facial areas, and other important tissues (e.g., facial nerve, ocular globe, palpebral tissues) is determined. The final score resulting in Group II categorization is based on three grades of different severity: Grade I (minor), 1 to 6; Grade II (moderate), 7 to 24; and Grade III (grave), greater than 25. By means of Group II categorization the following can be evaluated: (1) type and severity of functional and aesthetic lesions; (2) adequate timing of treatment; (3) convenient treatment; (4) type and severity of functional and aesthetic sequelae; and (5) probability of successful treatment of sequelae.
