Previous research has developed a pneumatically driven device for delivering a controlled mechanical insult to cultured neurons. The neuronal cell culture was injured by applying a transient air pulse to a culture well fitted with a highly elastic Silastic culture well bottom. In response to the pressure pulse, he Silastic culture well bottom deformed, stretched the attached cell culture, and r...

In retinal detachment surgery, Chawla (I97I) had excellent results using a 7-mm. encircling silastic band, cauterization of the edges of the tear by cryocautery, and evacuation of the subretinal fluid (Schepens, Okamura, and Brockhurst, I957). He felt that the technique was simpler than scleral dissection and safer than the supramid encircling suture. The present study has the following aims: (...

AIMS To describe a method of securing indwelling O'Donohughe's lacrimal tubes in dacryocystorhinostomy using two 3-4 mm Watski sleeves. METHODS The operative technique used to secure the sleeves into position on the lacrimal tubes is described. Forty seven procedures with a follow up ranging from 3 to 30 months (mean 10 months) are reviewed. RESULTS The tubes and sleeves were well tolerated...

BACKGROUND Malar augmentation is a common cosmetic procedure utilizing silastic materials. We describe an uncommon complication of a silastic implant eroding into the anterior maxillary sinus wall resulting in chronic rhinosinusitis (CRS). METHODS A literature review is presented describing the presentation, surgical management and outcome of this uncommon adverse event. RESULTS An 80 year ...

A survey was mailed to members of The American Society of Ophthalmic Plastic and Reconstructive Surgery (ASOPRS) concerning the diagnosis and management of patients with epiphora. Specifically, the respondent was asked about his or her work-up and management of an older patient with epiphora whose nasolacrimal system was patent on irrigation. Some pertinent findings were that 48 respondents did...
