Surgery is used for patients with smaller T2 lesions on the lower lip, if simple closure produces an acceptable cosmetic result.
Radiation therapy, which may include external-beam and/or interstitial techniques, as appropriate, has the advantage of producing a relatively better functional and cosmetic result with intact skin and muscle innervation, if a reconstructive surgical procedure is required.
Radiation therapy is usually selected for patients with T2 lesions that have minimal infiltration to preserve speech and swallowing. 
Surgery is reserved for patients for whom radiation treatment failed.
Neck dissection may be considered when primary brachytherapy is used.
Surgery, radiation therapy, or a combination of both are used for deeply infiltrative lesions.
