[Hyaluronic acid gel implants for correction of pathological conditions of the orbit and eyelids]. / Primenenie in''ektsionnykh implantatov na osnove gelia gialuronovoi kisloty pri patologii vek i orbity.

PURPOSE: To evaluate the effectiveness of injectable implants made of hyaluronic acid gel (HAG) in ophthalmoplastics. MATERIAL AND METHODS: The study included 57 patients (37 patients with lagophthalmos related to acute or chronic facial nerve palsy, endocrine ophthalmopathy; 20 patients with enophthalmos, anophthalmic syndrome). Depending on filler particle size, the patients received either intrapalpebral or intraorbital HAG injection. The biometric measures of palpebral fissure, the position of the eye/implant, and the condition of the cornea were evaluated during the follow-up period (12 months for eyelid and 18 for orbital injection). RESULTS: In the course of the follow-up, all patients showed reliable reduction of lagophthalmos; additionally, improvement of the condition of the cornea was observed in patients after intrapalpebral injection; patients after intraorbital injection exhibited reduction in enophthalmos, upper orbital palpebral fold retraction and upper eyelid excursion. No serious complications have occurred after the injection. CONCLUSION: As minimally invasive method of treating various pathologies of the orbit and eyelids, HAG fillers showed good clinical effectiveness and safety.
