RESUMO
Nevus of Ota, nevus of Ito and nevus of Hori are special melanocytic nevi that have a slate-brown or blue/grey coloring. They are pigmented disorders characterized by its heterotopic melanocytic dermal location and by blue/brown unilateral and sometimes bilateral facial patch in case of nevus of Ota, and in the supraclavicular, scapular, and deltoid region in case of nevus of Ito. It is more common in patients with Asian and dark-skinned ethnic backgrounds. Histologically, elongated, dendritic melanocytes are seen scattered mainly throughout the upper third of reticular dermis. An acquired variant is called Hori's nevus with more bilateral facial distribution, similar to melasma. Dermal melanocytosis can also occur elsewhere on the body, including inside the mouth. Despite its benign nature, patients frequently seek therapy because of its facial involvement. QS lasers are used effectively to treat these lesions. The number of treatment sessions correlates with clinical improvement. Post laser hypo- and hyperpigmentation are common side effects mainly affecting patients with darker skin.

OBJECTIVE: This study aimed to compare the outcomes of turbinoplasty assisted by microdebrider and by diode laser (980 nm wavelength). METHODS: Forty patients suffering from bilateral nasal obstruction were randomly divided into two equal groups. One group was managed with microdebrider-assisted turbinoplasty and the other with diode laser assisted turbinoplasty. The patients were followed up for six months post-operatively. RESULTS: After six months, total success rates were 90 per cent for the microdebrider group and 85 per cent for the diode laser group. There were no significant differences between the two groups regarding success rate, post-operative complications or operative time. CONCLUSION: These two techniques are equally safe, reliable, successful and non-invasive.
