A thorough examination of the lesion or lesions in question and any associated areas for treatment is essential. An assessment of the patient's overall health status should be performed. Findings may mandate further evaluation by laboratory tests and diagnostic studies, thus avoiding surgical complications.

The lesion should be evaluated for size, location, proximity to old scars, and relationship to potentially dangerous areas or natural skin lines. Any unusual features or preexisting abnormalities, such as eyelid ptosis or nasal alae asymmetry, should be carefully recorded. This documentation is especially important if the lesion occurs in close proximity to the proposed surgery site. Nasal valve insufficiency may be anticipated in planning for tumor removal and/or reconstruction for defects larger than 1 cm on the ala, sidewall, or alar crease. [20]
