Modification of the sublabial approach to midface, nasopharynx, and postnasal tumors.

The midline degloving approach to midfacial and nasosinal tumors is a procedure consisting of elevation of the midfacial soft tissue from a sublabial approach. A modification consisting of a composite flap laterally based on periosteum and soft tissue prevents flattening of the side of the nose. The method has distinct advantages over the transnasal, transpalatal, or lateral rhinotomy approach, giving wide exposure without external scars or disfigurement, and thus is suitable for benign as well as malignant lesions.
