OBJECTIVE To describe weakness of the orbicularis oculi muscle after external dacryocystorhinostomy (DCR) and propose an anatomic explanation for the complication. DESIGN Retrospective, observational study. PARTICIPANTS Sixteen patients (13 female, 3 male) with a mean age of 60 years (median, 61 years; range, 34-85 years). METHODS A retrospective(More)
Distichiasis is a rare congenital or acquired condition in which an accessory row of eyelashes arises from the posterior lamella of the eyelid margin. Previously described surgical techniques to treat distichiasis can result in complications including trichiasis, loss of normal eyelashes, cicatricial entropion, and eyelid margin deformities. We describe a(More)
A 43-year-old woman (Case 1), 63-year-old man (Case 2), and a 67-year-old man (Case 3) presented with diplopia (Cases 1, 2, and 3) and upper-eyelid ptosis (Cases 1 and 3). The cases had preceding cranial nerve V1 disturbances ranging from 3 months to 8 years. Each demonstrated complete internal ophthalmoplegia and external ophthalmoplegia. No case had a(More)
In vivo implants of demineralized dentin matrix into muscle induce the formation of bone within the muscle. As with bone matrix implants, the bone induction appears to follow a chondrogenic pathway. Outgrowth cells from explants of neonatal rat muscle respond to bone matrix, in vitro, by expressing a heightened synthesis of sulfated proteoglycans and type(More)
BACKGROUND Fluid resuscitation remains a fundamental component of early burn care management. However, recent studies suggest that excessive volumes of resuscitation are being administered. Overresuscitation results in negative sequelae including abdominal and extremity compartment syndromes. Elevated intraocular pressure (IOP) has been described as another(More)
Blindness caused by ischemic optic neuropathy in the hospital setting occurs perioperatively and in critically ill patients, but its etiology remains ill defined. We describe four critically ill patients who developed blindness within 1 mo of one another. Three cases occurred outside of the operative arena. Potential risk factors for the development of(More)
OBJECTIVE To evaluate the successes and challenges of endoscopic orbital floor fracture repairs. METHODS We analyzed 53 orbital floor repairs and recorded the indications for surgery, factors that complicated the endoscopic repair or necessitated conversion to an open approach, and outcomes for each. RESULTS Forty-five procedures were completed(More)
