Cause Analysis and Surgical Treatment of Aponeurotic Ptosis With Upper Eyelid Depression

Ptosis and upper eyelid depression were previously diagnosed as 2 separate diseases. The authors found that in patients with aponeurotic ptosis accompanied by upper eyelid depression, the main cause of upper eyelid depression was impaired dynamic transmission of the levator aponeurosis.

To analyze the causes of upper eyelid depression in patients with aponeurotic ptosis accompanied by upper eyelid depression and to introduce the best treatment methods.

The authors enrolled 15 eyes (11 patients) with aponeurotic ptosis accompanied by upper eyelid depression from October 2021 to August 2022. The authors analyzed the causes of upper eyelid depression in those patients and performed aponeurotic ptosis correction surgery and orbital septum fat release surgery. After 6 to 12 months of follow-up, the authors reviewed the patient's medical records and photographs to evaluate the treatment outcomes.

After surgery, ptosis was corrected and upper eyelid depression significantly improved in all the patients. One patient had poor eyelid morphology and upper eyelid depression due to habitual brow lifting, which was relieved after an injection of botulinum toxin into the frontalis muscle. One patient had overcorrection of the upper eyelid depression on the affected side and no other complications.

The main cause of upper eyelid depression in patients with aponeurotic ptosis is impaired dynamic transmission of the levator aponeurosis. Aponeurotic ptosis repair surgery and orbital septum fat release surgery are simple surgical procedures that restore the normal anatomy and physiology of the upper eyelid and maintain the normal structure of the eyelid, with good post-operative outcomes.
