Piezosurgery in External Dacryocystorhinostomy.

Background: Dacryocystorhinostomy (DCR) can be performed via an external or endoscopic approach. The use of ultrasonic or piezosurgery has been well described for endoscopic DCRs but is lacking for external DCRs. This study presents a case series of external DCRs performed using piezosurgery evaluating results and complications.

Infection Rates after Periocular Surgery Utilizing New versus Re-Processed Monopolar Electrocautery.

Background: To determine if there is a difference in periocular post-operative infection rates when utilizing new versus re-processed monopolar electrocautery tips.

Methods: Retrospective cohort study of 4,976 consecutive surgical cases involving 17,149 procedures. Post-operative infections were identified using chart review, facility infection surveillance records, and surgeon reporting.

Risk of ocular blood splatter during oculofacial plastic surgery.

Purpose: To assess intraoperative blood splatter to the ocular surface and adnexa during oculofacial surgery.

Methods: Four surgeons and multiple assistants at three separate locations wore a total of 331 protective eye shields during 131 surgeries. Postoperatively, a luminol blood detection system was used to identify blood splatter on the shields.

Age-matched, case-controlled comparison of clinical indicators for development of entropion and ectropion.

Purpose. To analyze the clinical findings associated with involutional entropion and ectropion and compare them to each other and to age-matched controls. Methods.

Canalicular obstruction: a histopathologic case series.

Objective: To investigate the histopathologic causes of canalicular obstruction in a case series of patients treated by canalicular trephination for symptomatic epiphora.

Design: A university and private practice retrospective chart review.

Participants: The study involved 12 consecutive patients who underwent unilateral canalicular trephination with tissue retrieval for the treatment of canalicular obstruction.

Hydrogel explant extrusion masquerading as a malignant eyelid lesion.

Hydrogel was a commonly used material for scleral buckling in the early 1980s to the mid-1990s. Use of hydrogel ceased due to a high complication rate, including frequent migration. Various symptoms and clinical findings have been reported with hydrogel migration.

Percutaneous drainage and ablation as first line therapy for macrocystic and microcystic orbital lymphatic malformations.

Purpose: To review the management of orbital lymphangiomas and to propose a new treatment for both macrocystic and microcystic lymphatic malformations of the orbit.

Methods: A retrospective case series of all patients from the authors' practice from 2001 to the present who met the histopathologic and/or diagnostic imaging criteria for orbital lymphatic malformation was reviewed. Lymphatic malformation was diagnosed if there was a multilobulated pattern on CT or a cystic internal structure on ultrasonography.

Efficacy of pulsed electromagnetic energy in postoperative recovery from blepharoplasty.

Background: A novel medical device that has been approved by the Food and Drug Administration is available for treatment of postsurgical edema. The device emits a low-level, pulsed electromagnetic energy field, which modulates resting cell membrane potential, allowing a return to physiologic resting membrane potential.

Objective: To investigate the benefits of electromagnetic energy in eyelid wound healing.

Addition of dermis-fat graft to diminish cable visibility in frontalis suspension for patients with pre-existing deep superior sulci.

Purpose: To propose and demonstrate a technique modification for frontalis suspension to simultaneously address ptosis and diminish abnormalities related to deep superior sulcus defect.

Methods: Six patients underwent simultaneous frontalis suspension and placement of a superior sulcus dermis-fat graft.

Results: Postoperative visibility of the cables, anticipated in patients with deep superior sulci, was prevented in these 6 patients.

Uveal melanoma with massive extrascleral extension via pars plana vitrectomy sites.

A 74-year-old man underwent cataract extraction and 4 months later developed a macula-off retinal detachment. The retinal detachment was repaired via pars plana vitrectomy. Postoperatively, hyphema and dense vitreous hemorrhage developed.
