Surgical correction of Tessier number 8 cleft.
The number 8 Tessier cleft can be a discrete horizontal shadow at the level of the lateral canthus of the palpebral fissure or a true coloboma with absence of the commissure between the upper and lower eyelids. A surgical technique, which has been used in eight patients, is described to correct this congenital defect. Four flaps are created and transposed as two Z-plasties. The lateral canthal ligament is fixed to the lateral orbital rim, and the orbicularis muscle is interdigitated to restore its continuity. This procedure reconstructs the depth of the conjunctival fornix, provides proper form and length to the palpebral fissure, and restores continuity and an anatomic angle to the malformed canthus.
