Aim Of The Study:
Injectable fillers are a popular treatment for sunken upper eyelid (SUE) deformity, but their efficacy and duration are limited. This study evaluated the clinical efficacy and safety of blunt separation combined with an uncrosslinked sodium hyaluronate compound solution for treating SUE in Asians.
Methods:
Twenty-seven Chinese patients (22 women, five men) with SUE underwent blunt separation to loosen subcutaneous adhesions. After disrupting the dermal layer, an uncrosslinked sodium hyaluronate solution was injected to stimulate collagen regeneration. Symptom improvement, recurrence, safety, and patient satisfaction were assessed.
Results:
Park S grading scores significantly improved after-treatment, 6 months, and 1 year (p < 0.05) immediately. Patients experienced mild pain, erythema, and swelling. Four had post-treatment bruising, which resolved within 5-8 days. No other adverse events or recurrences were observed, and patient satisfaction was high.
Conclusions:
This single-arm trial suggests that blunt separation with uncrosslinked sodium hyaluronate is a safe and effective SUE treatment with minimal side effects, the findings indicate potential for clinical application.
