Use of Pericranial Flap Coverage in Cochlear Implantation of the Radical Cavity: Rationale, Technique, and Experience.

Conference Otolaryngol Head Neck Surg · September 2016 Cochlear implant (CI) surgery in the setting of an open mastoid cavity is evolving. Two strategies are commonly pursued: a staged approach, clearing the disease, closing the meatus or the external auditory canal (EAC), and reevaluating in 3 to 6 months pri ...

Racial Differences of Pigmentation in the Human Vestibular Organs.

Conference Otolaryngol Head Neck Surg · September 2016 OBJECTIVES: Melanin pigmentation is present in the human inner ear. In this study, we quantify the melanin pigmentation in the vestibular system and examine racial differences of vestibular melanin pigmentation using human cadaveric temporal bone specimens ...

Measuring Success: Cost-Effectiveness and Expanding Access to Cochlear Implantation.

Conference Otol Neurotol · February 2016 Only a small fraction of patients with profound sensorineural hearing loss have access to cochlear implantation with the majority of these affected people living in developing countries. Cost effectiveness analysis (CEA) is an important tool to demonstrate ... Full text Link to item Cite

Determinants of resident competence in mastoidectomy: role of interest and deliberate practice.

Conference Laryngoscope · December 2013 OBJECTIVES/HYPOTHESIS: This study explores the influence of selected factors on achievement of competency in mastoid surgery. STUDY DESIGN: A prospective study of surgical performance and a retrospective survey of learner and training factors. METHODS: The ... Full text Link to item Cite

A comparison of mastoidectomy learning curves in otolaryngology-head and neck surgery residents

Conference Laryngoscope · January 1, 2011 OBJECTIVES:/Hypothesis: The purpose of our study was to explore factors that might influence the trajectories in residents' learning curves of surgical performance in the mastoidectomy procedure. Study Design: Retrospective-cohort study. Methods: Mastoidec ... Full text Cite

Using a virtual reality temporal bone simulator to enhance surgical competency in procedural tasks: A pilot study

Conference Laryngoscope · January 1, 2011 OBJECTIVES: The purpose of our study is to identify the potential roles of a virtual reality (VR) temporal bone simulator in the Otolaryngology residency program.

Programmatic challenges in obtaining and confirming the pneumococcal vaccination status of cochlear implant recipients.

Conference Otol Neurotol · October 2010 BACKGROUND: Bacterial meningitis represents a substantial concern for individuals with cochlear implants (CIs). METHODS: Chart review and direct patient and family correspondence to ascertain vaccination status. INTERVENTION: Information dissemination via ... Full text Link to item Cite

Efficient quantification of afferent cochlear ultrastructure using design-based stereology.

Conference J Neurosci Methods · January 30, 2006 The afferent synapse between the auditory nerve fiber and the inner hair cell (IHC) represents a critical junction for hearing. Elucidation of the structure at this site will help establish the substrate for normal sound encoding as well as pathologic proc ... Full text Link to item Cite

Cochlear implant outcome is not influenced by the choice of ear.

Conference Ear Hear · August 2005 OBJECTIVES: This study tested the hypothesis that patients with residual hearing in the nonimplanted ear had the same cochlear implant benefit whether the implanted ear had profound or severe hearing loss. DESIGN: A retrospective chart review of adult coch ... Full text Link to item Cite

Effects of central nervous system residua on cochlear implant results in children deafened by meningitis.

Conference Arch Otolaryngol Head Neck Surg · May 2004 BACKGROUND: This study explored factors associated with speech recognition outcomes in postmeningitic deafness (PMD). The results of cochlear implantation may vary in children with PMD because of sequelae that extend beyond the auditory periphery. OBJECTIV ... Full text Link to item Cite

Squamous cell carcinoma of the temporal bone: a radiographic-pathologic correlation.

Conference Arch Otolaryngol Head Neck Surg · July 2001 OBJECTIVE: To assess the utility of a previously proposed staging system for patients with primary squamous cell carcinoma of the temporal bone. METHODS: Retrospective chart review of 15 patients treated for squamous cell carcinoma of the temporal bone ove ... Link to item Cite

A model of educational resource use by children with cochlear implants.

Conference Otolaryngol Head Neck Surg · September 1997 We have tracked patterns of use of educational and rehabilitative resources as part of an initial assessment of cost-benefit ratios of cochlear implants in children. Forty-two children with cochlear implants in the Listening Center at Johns Hopkins program ... Full text Link to item Cite
