Abstract:Objective To investigate the effects and prognosis of Mohs surgery for treating craniofacial cutaneous malignant tumors, such as basal cell carcinoma (BCC), squamous cell carcinoma (SCC). Bowen's disease and actinic keratosis (AK) and analyze the clinical characteristics of craniofacial cutaneous malignant tumors. Methods Totally 411 cases of cutaneous malignant tumors without metastasis were enrolled, of which 256 cases were performed the Mohs microsurgery (group A), 130 cases were performed surgical operation with the traditional intraoperative frozen-section examination (group B), 25 cases were performed classic surgical operation (group C). Adjacent flap, myocutaneous flap, skin graft or direct suture was used to repair the wound. All were followed up for 3 to 5 years. Results In group A, 248 cases were Ⅰhealing with skin flaps and skin grafts all survived; 8 cases were Ⅱhealing, 2 cases recurred (0.8%). In group B, 125 cases were Ⅰhealing, 5 cases were Ⅱhealing, 7 cases recurred (5.4%). In group C, all cases were Ⅰhealing, 4 cases recurred (16%). The recurrence rate was statistically differentanlong thro groups (p < 0.05). Conclusions Mohsmicrosurgery is the first choice to treat craniofacial cutaneous malignant tumors, which can resect tumor completely, at the same time reserve the normal skin tissues to the greatest extent and reduce the excessive damage to patients' appearance by operation.
