ĐÁNH GIÁ HIỆU QUẢ CỦA BOTULINUM TOXIN A TRONG ĐIỀU TRỊ TẠM THỜI QUẶM MI DƯỚI TUỔI GIÀ

Abstract

Objective: Evaluate the efficacy of botulinum toxin A in the temporary treatment of eyelid droop in the elderly. Study Design: Non-control group experimental clinical study on a series of cases. Study Sample: 34 patients with 44 eyes. Method: 34 patients diagnosed with eyelid droop in the elderly (44 eyes), who did not want or were not yet able to undergo surgical treatment, were assigned to receive botulinum toxin A injection as an alternative. Clinical symptoms, patient satisfaction levels, and eyelid laxity were assessed before and after injection. The time of eyelid droop recurrence was recorded. Results: The botulinum toxin A injection method was performed quickly and simply. The anatomical position of the lower eyelid was restored in 40 out of 44 eyes with significant improvement in clinical symptoms and high satisfaction levels. The average effective duration of botulinum toxin A was 12 weeks, with a gradually decreasing success rate over time. There was no change in eyelid laxity before and after injection, indicating that botulinum toxin A does not affect the outcomes of future surgery. The horizontal direction of eyelid laxity was inversely correlated with the effective duration of botulinum toxin A. Conclusion: Temporary treatment of eyelid droop in the elderly with botulinum toxin A injection is a highly effective method with very few complications and does not affect the outcomes of future eyelid droop surgery
