Technique and indications of extended sublabial rhinotomy ("midfacial degloving").

Midfacial degloving is an extended sublabial rhinotomy, which permits good bilateral access to the nasal and paranasal cavities, the base of the skull, and the clivus. The incisions leave no visible scars. The access is suitable for large benign tumours (such as nasopharyngeal fibromas or inverted papillomas), but can also be used for malignant tumours. It can be enlarged by supplementary incisions to meet the demands of tumour surgery.
