Disease relevance of Stapes Surgery

• OBJECTIVE: To determine the incidence of benign paroxysmal positional vertigo (BPPV) following stapedectomy in a patient group and the efficacy of the Epley maneuver in this group [1].
• We report a patient with bilateral cholesteatomas, each following an initially successful stapedectomy for conductive hearing loss due to stapedial fixation from otosclerosis [2].
• This situation may occur in the presence of severe tympanosclerosis, otosclerosis, congenital ossicular malformations, and revision surgery for either stapedectomy or chronic ear disease [3].
• To determine new guidelines for stapedectomy in patients with both Meniere's disease and otosclerosis, we studied the position of the saccular membrane and Reissner's membrane in relation to the stapes footplate in eight temporal bones from patients with Meniere's disease [4].
• It is concluded that a daily sodium fluoride intake of 1 to 3 mg in a low-fluoride area is too small to have a significant effect on hearing impairment after stapedectomy [5].

Psychiatry related information on Stapes Surgery

• Speech discrimination in advanced otosclerosis following stapedectomy [6].

High impact information on Stapes Surgery

• Numerous attempts to deal surgically with otosclerosis were made before the current method of stapedectomy with stapes prosthesis was established [7].
• Two clinical studies analyze the long-term hearing results and complications in patients who had undergone CO2 laser stapedectomy revision (59 patients) and CO2 laser stapedotomy (153 patients) [8].
• CONCLUSIONS: The Nitinol piston greatly simplifies the stapedectomy procedure by taking the need for a hand operated instrument out of the surgeon's hands [9].
• An Internet survey of the relevant literature in English shows a scarcity of publications on the incidence of BPPV following stapedectomy [1].
• OBJECTIVE: The molecular defect in patients with X-linked mixed deafness showing a perilymphatic gusher at stapedectomy (DFN3) has been attributed to mutations in the POU3F4 gene [10].

Chemical compound and disease context of Stapes Surgery

• Ipriflavone (7-isopropoxy-isoflavone) was attempted to relieve tinnitus of otosclerotic patients prior to stapedectomy and continuing the treatment postoperatively in a 6 months regimen [11].

Biological context of Stapes Surgery

• Patients who underwent stapedectomy for reasons other than otosclerosis and those with inadequate post-operative bone conduction threshold data were excluded [12].
• Conductive hearing loss can be relieved through stapedectomy in patients with osteogenesis imperfecta with about the same level of predictability as in those with otosclerosis [13].
• This paper presents a small series of 29 stapedectomies in patients aged 21 or less; 19 for otosclerosis, 10 for other pathologies associated with stapedial fixation [14].
• The differences in hearing gain 1 year after stapedotomy, partial platinectomy, or total stapedectomy for otosclerosis were studied separately at 0.5, 1, 2, 4, and 8 kHz with the data available from 311 consecutive primary operations performed between 1980 and 1982 in the University of Nijmegen Department of Otorhinolaryngology [15].

Anatomical context of Stapes Surgery

• Round window closure is an uncommon complication of advanced otosclerosis found in 1% of 30,000 stapedectomy cases [16].
• The surgical techniques advocated in solving these problems are: placing a Robinson prosthesis on the floating footplate, utilizing the Lippy modification of the Robinson prosthesis for the problem incus, and performing only a stapedectomy for malleus fixation and otosclerosis [17].
• Samples of 3 mul to 5 mul of perilymph removed during 103 stapedectomies and samples of known alpha 1-trypsin activity were placed on slides coated with alpha 1-antitrypsin serum [18].
• OBJECTIVES: To determine the incidence of middle ear abnormalities in patients with bilateral otosclerosis, which could potentially affect successful stapedectomy, and the rates of success in these patients, including the chance of overclosure in the second ear [19].
• Sensorineural hearing loss as a result of surgical trauma to the inner ear occurred in revision surgery more frequently than in primary operations, cases with regrowth of otosclerotic bone to the oval window after stapedectomy having the greatest risk of labyrinthine trauma [20].

Associations of Stapes Surgery with chemical compounds

• Osseous disease of the external canal was removed and stapedectomy was performed, using the Argon laser on 15 patients [21].
• Sodium fluoride has now been used for 24 years in an effort to slow down or arrest sensorineural hearing nerve deterioration in patients with stapedial otosclerosis or after stapedectomy, as well as in patients with pure cochlear otosclerosis [22].
• What the history of stapedectomy reveals is the truth of the quotation from Ecclesiastes, "There is nothing new under the sun." Progress is only made when the Zeitgeist is right, by someone who puts together the truths of the past with the new discoveries of the present [23].
• Reversible auditory disorders after stapedectomy may be explicable by the intracochlear release of histamine [24].
• The objective of the study was to determine whether a titanium piston stapes prosthesis would be audiometrically and surgically equivalent to a Robinson stainless steel piston for stapedectomy [25].

Gene context of Stapes Surgery

• OBJECTIVE: To report a successful stapedectomy for stapedial fixation in a patient with Stickler syndrome type I (COL2A1) [26].
• Increased sensorineural hearing loss occurred in 0.8% of revision stapedectomy cases [27].
• This study of a possible relationship between the ABG and the remodeling of the niche in otosclerosis in a significant number of patients operated on by stapedectomy allows the authors to define six types of ABG shape, corresponding to various types of stapedial fixation and remodeling of the niche [28].
• In 5 ears stapedectomy for tympanosclerosis was performed; 9 patients had otosclerosis and 1 had Treacher Collins syndrome [29].
• Ten subjects with unilateral stapedectomies were presented with consonant-vowel nonsense syllables in low pass noise at 70, 95, and 110 dB SPL in each ear [30].

Analytical, diagnostic and therapeutic context of Stapes Surgery

• Thermal effects of laser stapedectomy in an animal model: CO2 versus KTP [31].
• Far-advanced otosclerosis. Cochlear implantation vs stapedectomy [32].
• PATIENTS: Intraoperative electrocochleography was performed in 22 patients 27-73 years of age undergoing a stapedectomy for otosclerosis under general anesthesia [33].
• This paper demonstrates that the BAHA offers a third treatment option for otosclerosis in patients who cannot or will not undergo stapedectomy and experience difficulty with conventional hearing aids [34].
