Alternative etiology and surgical correction of acquired lower-eyelid entropion.

When increased contraction of the levator muscle accompanied by the superior rectus muscle compensates for aponeurotic blepharoptosis, increased contraction of the inferior rectus muscle for foveation retracts the lower eyelid through the capsulopalpebral fascia, showing the lower sclera. We hypothesized that in patients with aponeurotic blepharoptosis, the capsulopalpebral fascia excessively retracts the posterior lamella of the lower eyelid alone while keeping the anterior lamella unretracted, especially in patients with both weak extension of the capsulopalpebral fascia to the pretarsal anterior lamella and increased contraction of the orbicularis oculi muscle, resulting in entropion. Aponeurotic reinsertion to the tarsus for the upper eyelid improved entropion in 15 younger patients.

Split thoracodorsal nerve funicular graft combined with functional latissimus dorsi musculocutaneous flap transfer for immediate facial reanimation after tumor ablation.

The authors report a case of immediate facial reanimation resulting from functional latissimus dorsi musculocutaneous flap transfer and funicular grafting of the thoracodorsal nerve after cheek tumor ablation. After wide excision of the tumor, including the facial nerve except the temporal branch and part of the zygomatic major muscle and masseter muscle, the authors reconstructed the cheek skin and provided movement by performing a small-segment latissimus dorsi musculocutaneous flap transfer using Harii's method and the defect of the buccal and marginal mandibular branches of the facial nerve by funicular grafting from one of the two funicles of the thoracodorsal nerve. After 6 months, the transplanted, small-segment latissimus dorsi muscle showed good voluntary movement, and the lower orbiculus oris and depressor oris presented good functional recovery.
