Extra-Conjunctival Implant

Extra-conjunctival Implants.

SIRS-Mr. Choyce has had the kindness to read my article. I would have appreciated his criticism all the more had he read it more carefully. His choice of the word " disservice" is unfortunate and unjustified. This is a new departure in the technique of implants, with a minimum of foreign material buried under conjunctiva, in an attempt at preventing sepsis and extrusion. My list of thirteen cas...

Extra-conjunctival Implants.

To the Editorial Committee of the BRITISH JOURNAL OF OPHTHALMOLOGY SIRS-The technique described by Nairac (1954) is ingenious, but founded upon a doubtful principle. Most authorities on orbital implants (movable ocular prostheses) agree that, to stand a chance of being retained for more than 5 years, an implant must be completely enclosed in both Tenon's capsule and the conjunctiva (Choyce, 195...

Extra-conjunctival Orbital Implants.

Silicone implant to extra-ocular muscles.

A PROCEDURE which would allow the lengthening of an extra-ocular muscle beyond that which is usually obtained from the conventional surgical techniques would be of definite advantage in large-angle strabismus and strabismus fixus. Since silicone rubber is well tolerated by ocular and non-ocular tissues, the implantation of a small, thin sheet of this material to lengthen an extra-ocular muscle ...

Extra- and Intracochlear Electrocochleography in Cochlear Implant Recipients.

OBJECTIVE To monitor cochlear function by extra- and intra-cochlear electrocochleography (ECoG) during and after cochlear implantation and thereby to enhance the understanding of changes in cochlear function following cochlear implantation surgery. METHODS ECoG responses to acoustic stimuli of 250, 500 and 1,000 Hz were recorded in 9 cochlear implant recipients with presurgical residual heari...
