NCT07466706

Brief Summary

this study reports the incidence of levator muscle dysgenesis among patients with simple congenital myogenic ptosis. In addition, the study aims to describ the nature of the dysgenesis, including the gross appearance of the muscle intraoperatively as well as the histopathological features under the microscope, correlation between the degree of dysgenesis and the preoperative ptosis assessment, and evaluation of the surgical outcome after levator muscle resection. Also, this research aims to shed light on the role of aponeurotic developmental anomalies, specifically fibrotic changes and maldevelopment in the pathogenesis of simple congenital ptosis.

Outcome Measures

Primary Outcomes (1)

  • Nature and Pattern of Levator Muscle Dysgenesis

    Characterization of gross intraoperative findings (fibrosis, fatty infiltration, aponeurotic abnormalities) and microscopic histopathological features across proximal, middle, and distal muscle segments. Distribution and predominance of abnormalities will be documented.

    Preoperative clinical assessment compared with histopathological findings obtained at time of surgery.

Study Arms (1)

ptosis

ACTIVE COMPARATOR
Procedure: levator muscle resection

Interventions

All patients will undergo levator muscle resection under general anesthesia. A standard skin incision will be made through the eyelid crease and orbicularis muscle. The orbital septum will be opened to expose the preaponeurotic fat, which will be retracted to identify the Levator Aponeurosis (LA), Whitnall's ligament, and the Levator Palpebrae Superioris (LPS) muscle belly. * Macroscopic Assessment: Before resection, the LA and surrounding tissues will be meticulously inspected and photographed. We will document: 1. Fibrotic Changes 2. Aponeurotic Defects 3. LPS Characteristics 4. Whitnall's Ligament * Surgical Repair: Levator resection will be performed based on the degree of ptosis and levator function (utilizing Beard's tables or Berke's formula). In cases of aponeurotic dehiscence, the identified aponeurosis will be advanced and reattached to the anterior surface of the tarsus using double-armed 5-0 polyester sutures.
