Treatment

Nevus of Ota is a rare pigmentary disorder characterized by blue-gray or brown hyperpigmentation that primarily affects the face along the innervation of the trigeminal nerve. Its origin is associated with the accumulation of melanocytes in the dermis and may have a congenital or acquired component.

This type of nevus can, in some cases, involve the sclera, cornea, oral mucosa, or nasal mucosa. Several approaches have been used to manage nevus of Ota, including chemical peels, dermabrasion, cryotherapy, ophthalmological follow-up, and, rarely, surgery. However, these methods have limited results, risk of scarring, and high recurrence.

Currently, with advances in technology, the Q-Switched laser is considered the most effective therapy for nevus of Ota. Using ultrashort, high-energy pulses, it selectively fragments dermal pigments without damaging the adjacent skin. Providing progressive lesion lightening, safety, and low complication rates when administered properly.

In this clinical case, 8 sessions of ACROMA-QS®, a Q-Switched laser handpiece compatible with the ETHEREA-MX® and ZYE® platforms, were performed. A progressive and personalized approach is recommended, considering the patient's skin characteristics and pigment depth.
