A straight pick was used for the gradual application of cement over the ossicular gap between incus and stapes (fig's.2, ,3). 3). generally, one to two applications were sufficient to make an ossicular bridge between incus and stapes. 35 minutes was given for the setting of the cement.
A total of 17 patients were treated with bone cement only; in 4 of these patients, hearing loss reoccurred within 6 months. the procedure was repeated in 2 of these patients using both bone cement and wire with satisfactory hearing results (airbone gaps, 7.5 and 8.8 decibels hearing level db hl) after 1 year.

No complications in the middle ear related to bone cements were encountered. conclusions incudostapedial rebridging ossiculoplasty with ionomeric bone cement is a reliable method for ossicular reconstruction that is cost effective and offers satisfactory hearing results in.
While incudostapedial rebridging ossiculoplasty is the most common indication of bone cement ossiculoplasty, bone cements also can be used in different situations such as between malleus and stapes in the absence of incus, 5 in case of incus long arm necrosis in stapedotomy cases, 3 to secure ossiculoplasty prostheses like torp or porp, 12 and.
Mean abg closure ranged from 15 db to 23 db in patients treated with bone cement across 11 studies. most of the two‐armed studies did not show a statistically significant difference between the use of bone cement and various conventional rebridging techniques, including allograft or autograft interposition and partial ossicular replacement.
Objectiveshypothesis to evaluate the effectiveness of bone cement on mean postoperative air–bone gap (abg) and the proportion of abg closure to within 20 db in patients undergoing ossicular chain.
To evaluate the effectiveness of bone cement on mean postoperative air–bone gap (abg) and the proportion of abg closure to within 20 db in patients undergoing ossicular chain reconstruction or revision stapes surgery. data sources. pubmed, embase, and central. methods. a systematic search was conducted.
Bone cement becomes stable and very minimally soluble after hardening. there is no information about ototoxicity of glass ionomer bone cement. in this study we aimed to find out possible ototoxic effect of glass ionomer bone cement powder. materials and methods the study assessed in afyon kocatepe university faculty of medicine.

Bone cement is a good and cheap option for some ossicular chain problems such as incudostapedial rebridging. the purpose of this retrospective study is to evaluate the audiologic results after reconstruction of three different types of ossicular chain defects, using bone cement.
Bone cement is a good and cheap option for some ossicular chain problems such as incudostapedial rebridging. the purpose of this retrospective study is to evaluate the audiologic results after reconstruction of three different types of ossicular chain defects, using bone cement. group 1 consists of 42 patients who underwent an ossiculoplasty using bone cement between the damaged long.
Bone cement is prepared and shaped easily and after getting hard and it doesnt get affected by any fluids like blood . the majority of used area of bonecement is the defect of incus long process . most preferred pathology to use bonecement is incus long process defect and it is used between incus and stapes for incudostapedial rebridging.
Bone cement reconstruction of the ossicular chain was performed from incus to stapes in the absence of a long arm or lenticular process of the incus. the clinical data of the patients were evaluated by otoscopic examination and audiometry. results: after incudostapedial rebridging ossiculoplasty we performed; out of 19 patients, 10 had 20 db.
Er ear. in patients requiring revision ossiculoplasty, half of failures are due to prosthesis displacement. bone cements have been used as prosthetic material in craniofacial surgery, and their adhesive and osseointegrative properties make them ideal for use in ossicular reconstruction. methods twentyfour adult male guinea pigs underwent a postauricular surgical approach for access to the.
Patient underwent exploratory tympanotomy. incudostapedial joint identified intraoperatively , stabilized with glass ionomer bone cement. post operative air bone gap evaluated after 6 months. a postoperative airbone gap less than 20 db was achieved. hearing results with bone cement ossiculoplasty are satisfactory.
After the ossicular defect has been prepared for the placement of bone cement (as explained above), the powder (hydroxylapatitebased mixture of tetracalcium phosphate) and the liquid (diluted citric acid) component of the bone cement (otomimix calcium phosphate, ref: 70143266, biomet microfixation, jacksonville fl, usa) are mixed thoroughly.
Cholesteatoma formation may occur many years after a temporal bone fracture. 92 93 additionally, when the attic, antrum, or mastoid is involved, it may take many years to experience symptoms as the growth must involve the ossicular chain, labyrinth, or facial nerve before symptoms develop. there are four pathogenic mechanisms responsible for.
Literature, bonecement usage for some type of ossicular chain problems as an economic application, may have successfully functional results. longer term followup results may help to understand longterm efficiency of bonecement. references 1. kalcioglu mt, tan m, fleerakkers j. the use of bonecement for ossicular chain defects.
Objectivethe objective of this study was to compare hearing results in patients undergoing ossiculoplasty with bone cement (bc) vs partial ossicular replacement prosthesis (porp) in cases of incudo.
More than 75 of cases had a postoperative airbone gap (abg) 25 db in all groups with group c having 85 of cases with 25 db abg at 1year after surgery. no statistically significant difference observed in abg at 3 months and 1year. conclusion: abnormalities of incus are commonly observed during tympanomastoid surgeries and ossiculoplasty.
Chronic otitis media is one of the major health issues worldwide resulting in partial or complete loss of conductive hearing mechanism including the tympanic membrane and ossicular assembly. the aim of the study is to assess hearing improvement after reconstructing the incudostapedial joint with glass ionomer cement. here, a prospective observational study was done in a.

Bone cement serves as a good adjunct for ossiculoplasty. it is easy to prepare and apply with fast setting times and good biocompatibility. it can be molded to augment the ossicular remnant, allowing ossicle preservation. ninety percent of patients who underwent bone cement reconstruction have reported an airbone gap closure of 20db or better.
