Silastic and gelatin film sheeting in tympanoplasty. 1975

J Falbe-Hansen, and M Tos

In 78 patients, representing 10% of the most severe case of chronic otitis media and in whom the mucosa from the promontory had been removed or severely damaged, the promontory was covered in one-stage mastoidectomy-tympanoplasty with a large piece of thin silastic or of Gelfilm. The results in the silastic group, comprising 50 patients, and in the Gelfilm group, comprising 28 patients, were compared on the basis of various criteria. The results proved better in the Gelfilm group. In particular, the percentage of recurrent perforations was considerably lower than in the silastic group. In one-stage operations, which we prefer, it is therefore recommended to use Gelfilm rather that silastic.

D012826	Silicone Elastomers	Polymers of silicone that are formed by crosslinking and treatment with amorphous silica to increase strength. They have properties similar to vulcanized natural rubber, in that they stretch under tension, retract rapidly, and fully recover to their original dimensions upon release. They are used in the encapsulation of surgical membranes and implants.	Elastomers, Silicone,Rubber Silicone,Silicone Rubber,Elastosil,Microfil,SE-30,Elastosils,Microfils,SE 30,SE30,Silicone Elastomer
D014432	Tympanic Membrane	An oval semitransparent membrane separating the external EAR CANAL from the tympanic cavity (EAR, MIDDLE). It contains three layers: the skin of the external ear canal; the core of radially and circularly arranged collagen fibers; and the MUCOSA of the middle ear.
