Surgical approach in a rare case of coloboma-choristoma

Area of Science:

• Ophthalmology
• Plastic Surgery
• Pediatric Surgery

Background:

• Congenital eyelid defects, including coloboma and dermolipoma, can occur in isolation or with craniofacial anomalies.
• Tessier craniofacial clefts represent a spectrum of congenital malformations affecting the face and skull.

Purpose of the Study:

• To describe the rare co-occurrence of upper eyelid coloboma and lower eyelid dermolipoma in an infant with a Tessier no. 0-1 cleft.
• To present a surgical technique for correcting congenital palpebral coloboma using specific tissue grafts.

Main Methods:

• Surgical intervention involving a flap of subconjunctival choristoma.
• Grafting of reshaped cutaneous and tarsal portions from a preauricular anlage.
• Correction of congenital upper eyelid coloboma and lower eyelid dermolipoma.

Main Results:

• The described surgical technique resulted in a virtually complete repair of the congenital eyelid defect.
• An acceptable functional and cosmetic outcome was achieved post-operatively.
• Demonstrated successful management of a complex congenital eyelid malformation.

Conclusions:

• The presented surgical approach is effective for correcting congenital palpebral coloboma, particularly in complex cases.
• This technique offers a viable solution for managing combined eyelid defects associated with craniofacial anomalies.
• Highlights the importance of tailored surgical strategies for rare congenital eyelid malformations.
