Plastic Cryosurgery: Cryosurgery and its Cosmetic Effect
Nevus Ota is a congenital or acquired facial dermal melanosis that is rather rare in Caucasians but is observed frequently in Mongolian races (Kukita et al. 1981, Yamauchi et al. 1981). The pigmentation is usually unilateral and most pronounced on the eyelids and in the zygomatic and maxillary regions. It is composed of light brownish-blue to deep purplish-blue macules caused by an abnormal occurrence of melanocytes within the connective tissue. In Japan, this disorder is estimated to affect approximately 0.4 percent of the dermatology outpatient population (Yoshida 1952) and 2.6 percent of plastic surgery outpatients (Suzuki 1991). The ratio of male to female patients is reported to be approximately 1:3 (Kukita et al. 1981, Suzuki 1991).
