Nevus of OTA



What are these? -- Nevi of Ota.

A dark brown, blue or gray patch on the face, which may be congenital or acquired. It is mostly unilateral (90%) which affect the forehead, temple, malar area, or periorbital skin.

Nevus of Ota is very common in Asian populations, and the male-to-female ratio is 1:4.8. It is caused by the entrapment of melanocytes in the upper third of the dermis, involving the distribution of the ophthalmic and maxillary branches of the trigeminal nerve. In some cases, it may also involve the ocular and oral mucosal surfaces.

After onset, nevus of the Ota may enlarge and darken in color and usually remains stable once adulthood is reached. The characteristic of the nevus may fluctuate according to personal and environmental conditions.





Any solution? –YES!
Q switched Nd:YAG laser(Revlite laser treatment), which is unquestionably the current treatment of choice for nevi of Ota with high success rates and minimal adverse effects. It works by destroying the dermal melanocytes selectively without causing harm to the surrounding tissue.






Revlite laser is a quick procedure (10-15 minutes) with only a mild pain. No scabs, hyperpigmentation and down time after the procedure. With a minimum of 6 treatments, skin pigmentation is reduced dramatically with a brightened skin tone.
