[Late results of stapedectomy after 15 years (author's transl)]. 1976

P Strauss, and M Strahl

Stapedectomy in Otosclerosis in using polyethylene struts or stainless-steel wire protheses results in permanent correction of the postoperative gap. The use of stainless-steel wire protheses however is successful with 94% of the patients regarding the postoperative gap, compared to 89% of the patients in using the polyethylene struts. The postoperative decrement of bone conduction is statistically significantly lower in the stainless-steel wire protheses than in polyethylene struts.

UI	MeSH Term	Description	Entries
D010040	Otosclerosis	Formation of spongy bone in the labyrinth capsule which can progress toward the STAPES (stapedial fixation) or anteriorly toward the COCHLEA leading to conductive, sensorineural, or mixed HEARING LOSS. Several genes are associated with familial otosclerosis with varied clinical signs.	Otospongiosis,Otoscleroses,Otospongioses
D011095	Polyethylenes	Synthetic thermoplastics that are tough, flexible, inert, and resistant to chemicals and electrical current. They are often used as biocompatible materials for prostheses and implants.	Ethylene Polymers,Ethene Homopolymers,Homopolymers, Ethene,Polymers, Ethylene
D001844	Bone Conduction	Transmission of sound waves through vibration of bones in the SKULL to the inner ear (COCHLEA). By using bone conduction stimulation and by bypassing any OUTER EAR or MIDDLE EAR abnormalities, hearing thresholds of the cochlea can be determined. Bone conduction hearing differs from normal hearing which is based on air conduction stimulation via the EAR CANAL and the TYMPANIC MEMBRANE.

D001299	Audiometry	The testing of the acuity of the sense of hearing to determine the thresholds of the lowest intensity levels at which an individual can hear a set of tones. The frequencies between 125 and 8000 Hz are used to test air conduction thresholds and the frequencies between 250 and 4000 Hz are used to test bone conduction thresholds.	Audiometries
D013201	Stapes Surgery	Surgery performed in which part of the STAPES, a bone in the middle ear, is removed and a prosthesis is placed to help transmit sound between the middle ear and inner ear.	Stapedectomy,Surgery, Stapes,Stapedectomies,Stapes Surgeries,Surgeries, Stapes
D013232	Steel	A tough, malleable, iron-based alloy containing up to, but no more than, two percent carbon and often other metals. It is used in medicine and dentistry in implants and instrumentation.	Steels
D013997	Time Factors	Elements of limited time intervals, contributing to particular results or situations.	Time Series,Factor, Time,Time Factor
