Bilateral Nevus of Ota Treated with Combination of CO2 Fractional Laser and 1064 nm Nd:YAG Laser
ABSTRACT: Ota’s nevus (nevus
fuscocaeruleus ophthalmomaxillaris) was first described by Ota in 1939. It is characterized
by blue–black or gray–brown dermal melanocytic pigmentation and typically
occurs in areas innervated by the first and second branches of the trigeminal
nerve. Mucosal pigmentation may occur involving conjunctiva, sclera, and tympanic
membrane (oculodermal melanocytosis), or other sites. Purpose: Describe the
clinical manifestation and therapy of bilateral nevus of Ota. Case: A
20-year-old female patient, complaint about dark patches in both of her cheek
and forehead since birth. Histopathology has not been done because patient
refused to do the biopsy. Diagnosis of bilateral nevus of Ota is made based on
anamnesis and clinical manifestations. Discussion: Pasien has undergo Nd:YAG
laser session for Ota’s nevus and the result was not satisfactory. Now patient
was given combination laser of CO2 fractional laser and 1064 nm Nd:YAG laser
for 4 sessions with 3 months interval. After four laser sessions, there has
been an improvement in the lesions as the lesions is getting lighter. The
purpose of CO2 fractional laser is to increase light delivery into the tissue
and for extruding material out of the skin. This laser combination aimed to
increase the ability to remove pigment as an alternative method without
inducing a systemic allergic reaction. Conclusion: Nevus of Ota is diagnosed
based on clinical finding. Combination therapy of CO2 fractional laser and1064
nm Nd:YAG is the mode of choice because of excellent results.
