Complications of the transconjunctival approach are uncommon. When they do occur, proper management results in a successful outcome.

Surgical correction of congenital blepharoptosis may be performed with autologous fascia lata, cadaveric allograft, or permanent suture material. The use of a frontalis muscle advancement flap is elegantly designed; however, its role in clinical practice remains to be defined. Advancement of the levator aponeurosis for senile blepharoptosis may be preformed via a minimally invasive small incision approach. Patients benefit with decreased operative time, edema, ecchymosis, and recovery times.

To assess longstanding alterations in human muscle innervation induced by botulinum toxin, we studied motor axons in the orbicularis oculi of nine patients previously injected with botulinum toxin for treatment of benign essential blepharospasm (BEB). Compared with untreated BEB and normal orbicularis oculi, muscle exposed to botulinum toxin developed persistent and cumulative alterations of innervation, including (1) thin, unmyelinated axonal collaterals that contact muscle end plates, (2) an increased number of muscle fibers innervated by individual terminal motor axons, (3) a profusion of unmyelinated axonal sprouts that end blindly, (4) an increased range of end plate sizes, and (5) multiple end plates on individual muscle fibers. The findings suggest that axonal sprouts which develop after botulinum-toxin-induced functional denervation can form new end plates. A single muscle fiber may then be innervated at separate sites by more than one axon.

Rosai-Dorfman disease, although historically described as benign and self-limiting, may cause significant morbidity and mortality involving multiple organ systems. Available treatment options may not control the disease. Further research and long-term clinical correlation is necessary.

Lower eyelid fat repositioning blepharoplasty in an intra-SOOF plane is an alternative technique to address the tear trough deformity. This technique provides excellent surgical results and high patient satisfaction. Convenient for both patient and surgeon, this technique is readily performed in an office-based procedure room under local anesthetic. Further follow-up will determine long-term outcomes.
