Сryosurgery possibilities for nevus in intermarginal eyelid space

Purpose. Assessment of the functional state of eye adnexal apparatus and eyeball after cryodestruction of the dermal eyelid nevus using modern cryosurgical equipment. Material and methods. The clinical studies were conducted in 17 patients (17 eyes) with nevus in the eyelid intermarginal space, with conducting nevus cryodestruction using an autonomous cryoapplicator of porous-permeable titanium nickelide. Results. The new generation cryogenic systems are remarkable for new properties compared to the known cryogenic apparatuses. They can significantly improve the surgery quality in cryotherapy due to a more distinct localization of cryotherapy and a high rate of heat removal from the altered tissue surface without damaging the surrounding tissues. Depending on the size of the pathological formation, exposure duration, the frequency of application repetitions per session, the nevus regression occurred within 1.5–2.0 months with preserving the integrity of the eyelid intermarginal space and the eye functional condition. Conclusion. The analysis of the data obtained evidences for a high clinical and cosmetic cryosurgery effectiveness for the eyelid nevus intermarginal space using an autonomous cryoapplicator of porous-permeable titanium nickelide. Key words: cryosurgery, dermal eyelid nevus, cryoapplicator of titanium nickelide.
