Description
Summary:We evaluated quantitatively, with electromyography, the function of orbicularis oculi muscle flaps in modified Hughes reconstructions of the lower eyelids. A modified Hughes procedure with a bipedicle orbicularis oculi flap was used to reconstruct large left lower eyelid defects after tumor excision in six consecutive patients. Standard needle electromyography and facial nerve conduction studies were performed on each reconstructed lower eyelid, and results were compared with those of the unoperated-on right lower eyelid. Electromyographic studies were performed between 143 and 517 days after division of the tarsoconjunctival flap. Blink reflexes and results of facial nerve studies were normal and similar on both sides. All operated-on eyelids demonstrated electromyographic activity during voluntary orbicularis contraction. The functional and cosmetic results were satisfactory in all patients. No complications of reconstruction, such as eyelid retraction, ectropion, tissue necrosis, or abnormal contour or thickness, occurred. A modified Hughes procedure using a bipedicle orbicularis oculi flap provides viable, electrically active muscle to the reconstructed lower eyelid and may enhance the functional results.
