The OOPS index makes it possible to accurately prognosticate hearing outcomes in adult and pediatric patients undergoing ossiculoplasty in both the short term and the long term.
Smoking is not a significant risk factor for anatomic failure of cartilage tympanic membrane graft or worsened audiometric outcome after ossiculoplasty. However, complications were significantly more common in smokers, supporting the practice of primary tympanostomy tube placement at the time of ossiculoplasty.
Use of the titanium stapes FPP during TORP ossiculoplasty provides a statistically significant advantage in short-term PTA-ABG closure and a higher rate of successful rehabilitation of conductive hearing loss. Further studies are necessary to assess any long-term advantages a FPP may offer.
Cartilage tympanoplasty with intubation achieves good anatomical and audiologic results when Eustachian tube dysfunction or craniofacial abnormalities are present. Significant hearing improvement was realized in a patient population that is characteristically more prone to problems.
cochlear from the ten most differently bi-regulated candidate genes were chosen for further q-PCR validation. As a result, Fcer1g, Nnmt, Lars2 (up-regulated) and Cuedc1 (downregulated) genes were proved to be differentially expressed between KI and WT group.Conlusion: GJB2 p.V37I KI mice presented progressive lateonset hearing loss with depletion in numbers of hair cell. Fcer1g, Nnmt, Lars2 and Cuedc1 genes were proved to be differentially expressed between KI and WT group. Introduction: The World Health organisation has identified chronic suppurative otitis media as a neglected condition affecting up to 330 million people worldwide, the burden of the disease located in impoverished countries. There are huge socioeconomic implications that support any progress towards the correct management of otorrhoea. The recent Lancet Commission on Global Surgery highlighted the need for NGOs to hardwire training into their programmes and that low cost simulation would be one avenue by which this might be achieved. With this in mind, we aimed to develop an ear surgery simulator appropriate for training in resource poor settings and to demonstrate its effectiveness in facilitating acquisition of headlight and microsurgical skills necessary to perform procedures via the ear canal, safely.Methods: A low-fidelity ear trainer was designed to emulate the ear canal and middle ear space. Face validity was assessed via questionnaires. Six tasks were developed, from headlight foreign body removal through to microscope-orientated tasks of foreign body removal, ventilation tube insertion, tympanomeatal flap raising, myringoplasty, and middle ear manipulation skills.Novices (medical students), those with limited otology experience ( junior ENT doctors) and experts (consultant otologists) were video-recorded performing each task. Videos were scored by a blinded observer, using a validated measurement tool and specially adapted task-specific checklist, in order to assess construct validity.Results: Face validity results confirmed that ET was a realistic representation of the ear. Construct validity results showed a statistically significant trend with experts performing better than those with limited experience performing better than novices.Conclusion: This study validates ET as a useful training tool to assess headlight and microsurgical skills required to perform otologic procedures. Further testing is now planned in the developing world setting.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
