Inter-rater agreement between 13 otolaryngologists to diagnose otitis media in Aboriginal and Torres Strait Islander children using a telehealth approach.

Introduction: Telehealth programs are important to deliver otolaryngology services for Aboriginal and Torres Strait Islander children living in rural and remote areas, where distance and access to specialists is a critical factor.

Objective: To evaluate the inter-rater agreement and value of increasing levels of clinical data (otoscopy with or without audiometry and in-field nurse impressions) to diagnose otitis media using a telehealth approach.

Design: Blinded, inter-rater reliability study.

Implantation and long-term assessment of the stability and biocompatibility of a novel 98 channel suprachoroidal visual prosthesis in sheep.

Severe visual impairment can result from retinal degenerative diseases such as retinitis pigmentosa, which lead to photoreceptor cell death. These pathologies result in extensive neural and glial remodelling, with survival of excitable retinal neurons that can be electrically stimulated to elicit visual percepts and restore a form of useful vision. The Phoenix Bionic Eye is a fully implantable visual prosthesis, designed to stimulate the retina from the suprachoroidal space.

Composite gelfoam/fascia graft: a novel technique in tympanoplasty surgery.

Background: Traditional tympanoplasty techniques require graft placement and then supporting material (GelFoam) as a two-step process. Both steps potentially disrupt accurate graft placement leading to failure and persistence of the perforation.

Methods: We demonstrate a novel technique for graft preparation and placement using composite gelfoam/fascia in which the gelfoam and fascia are compressed into a common layer and applied to the perforation and drum remnant in a single step.

Risk Factors for Facial Nerve and Other Nonauditory Side Effects Following Cochlear Implantation.

Objective: The purpose of this study was to characterize a cohort of patients with nonauditory side-effects (NASx) following cochlear implant (CI) surgery.

Study Design: Retrospective case review.

Setting: Tertiary referral center.

Validation of a 3D-printed human temporal bone model for otology surgical skill training.

Hypothesis: Three-dimensional (3D) printed temporal bones are comparable to cadaveric temporal bones as a training tool for otologic surgery.

Background: Cadaveric temporal bone dissection is an integral part of otology surgical training. Unfortunately, availability of cadaveric temporal bones is becoming much more limited and concern regarding chemical and biological risks persist.

Assessing Cochlear Length Using Cone Beam Computed Tomography in Adults With Cochlear Implants.

Unlabelled: : Developing a clinically viable technique for measuring cochlear length could enhance future electrode design of cochlear implants and surgical skills to improve clinical outcomes. While computed tomography (CT) has been used, metal artifact and the exposure to higher levels of radiation limits its use. More recently, cone beam CT (CBCT) has been used to assess the integrity of the implant array in situ, exposing implantees to lower levels of radiation while retaining image quality.

Speech Recognition Outcomes After Cochlear Reimplantation Surgery.

This study compares speech recognition outcomes before and after cochlear reimplantation surgery, in relation to clinical factors known before and at time of surgery. Between 2006 and 2015, 2,055 adult cochlear implant surgeries were conducted at this center, of which 87 were reimplantation surgeries (4.2%).

Neuroendocrine Adenoma of the Middle Ear: A Rare Histopathological Diagnosis.

Neuroendocrine tumours occur throughout the body but are rare in the head and neck region and particularly rare in the middle ear. Clinical findings are often nonspecific and therefore pose a diagnostic challenge. Furthermore, the nomenclature of neuroendocrine tumours of the middle ear is historically controversial.

Growth Rate Analysis of an Untreated Glomus Vagale on MRI.

Paragangliomas are slow growing, hypervascular neuroendocrine tumors that develop in the extra-adrenal paraganglion tissues. Paraganglioma involving the vagus nerve ganglia is termed glomus vagale. The slow growth of head and neck paragangliomas especially in the absence of symptom may obviate the necessity for any active intervention, in which case, a "wait and scan" policy is implemented involving long-term clinical and radiologic follow-ups.

Outcomes in Stapedotomy Surgery: The Learning Curve Redefined.

Objective: The aim of this study is to determine if the cumulative summation test for the learning curve (LC-CUSUM) and the cumulative summation graph (CUSUM) can be used to demonstrate landmark points of competence and maintenance of proficiency in stapes surgery over a continuous time period.

Study Design: Retrospective review from January 1999 until August 2014.

Setting: Tertiary referral hospital.

The semi-lunar meatoplasty.

Stenosis of the external auditory meatus is known to be problematic for the otolaryngologist. Establishment of an adequate meatoplasty is important to restore normal otologic physiologic function, whether the meatoplasty is performed as a primary operation or as an adjuvant procedure. Numerous techniques have been devised for performing a meatoplasty.

Rates of revision and device failure in cochlear implant surgery: a 30-year experience.

Objectives/hypothesis: To characterize revision cochlear implant surgery and quantify rates of revision and device failure.

Study Design: Retrospective review of 235 cases of revision cochlear implant surgery performed at the Sydney Cochlear Implant Center over a period of 30 years, between January 1982 and June 2011.

Methods: Patient demographics and characteristics of revision surgery were retrospectively extracted from a centralized database.

The vestibular schwannoma surgery learning curve mapped by the cumulative summation test for learning curve.

Objective: To demonstrate and quantify the learning curve for microsurgical excision of vestibular schwannoma in a newly formed neurootologic team by using the cumulative summation test for learning curve (LC-CUSUM). To secondarily identify the factors influencing postoperative facial nerve outcome.

Study Design: Retrospective review.

Cochlear implants and magnetic resonance scans: A case report and review.

Objective And Importance: Traditionally, magnetic resonance imaging (MRI) was contraindicated for patients with cochlear implants (CIs), due to concern about device displacement, overheating of the device or tissues, or direct damage to the device electrode. In addition, image artifact from the device magnet gave poor imaging information in the cranial and upper cervical spine region. Today, MRI is increasingly required in patients who have undergone cochlear implantation, and CI design and MRI protocols have therefore changed to allow implanted patients to safely enter the MRI field, in some cases without removal of the CI internal magnet.

Quality of life in postoperative vestibular schwannoma patients.

Objectives/hypothesis: To quantify the postoperative quality of life (QOL) in patients following vestibular schwannoma surgery in a new multidisciplinary skull base unit.
