Bovey Z Zhu, Jasmine Saleh, Kevin T Isgrig, Lisa L Cunningham, Wade W Chien
BACKGROUND: Delivery of therapeutic agents directly through the round window (RW) offers promise for treating sensorineural hearing loss. However, hearing loss can result from the surgical approach itself, and the reasons for this are poorly understood. We examined the hearing loss following the 3 major steps involved with the RW approach to access the mouse cochlea: bullostomy, RW puncture, and RW injection. METHODS: Twenty-one adult CBA/J mice underwent bullostomy alone, 10 underwent RW puncture, and 8 underwent RW injection with PBS with 5% glycerol...

The active middle ear implant Vibrant Soundbridge© provides a variety of coupling modalities of the floating mass transducer (FMT) to various structures of the ossicular chain and the round window. A retrospective analysis was performed on 125 subjects (n = 137 ears) (1) to compare the efficacy of the different FMT coupling modalities with increasing degree of hearing loss, (2) to compare the performance in speech outcome and the effective gain between the coupling types, and (3) to evaluate the risk of additional hearing loss of each coupling procedure...

BACKGROUND: Baro-otalgia is a common complaint among passengers in an aircraft, in particular those who had a recent upper respiratory tract infection. The underlying pathophysiology is secondary to unequal aeration of the middle ear cleft with the surrounding atmosphere and it can be explained using Boyle's Law. We describe an unusual presentation of baro-otalgia in a pilot secondary to cholesteatoma obstructing the aditus despite normal middle ear pressure equalization provided by a grommet in the ear...

The European Academy of Otology and Neurotology (EAONO) has previously published a consensus document on the definitions and classification of cholesteatoma. It was based on the Delphi consensus methodology involving the broad EAONO membership. At the same time, the Japanese Otological Society (JOS) had been working independently on the "Classification and Staging of Cholesteatoma." EAONO and JOS then decided to collaborate and produce a joint consensus document. The EAONO/JOS joint consensus on "Definitions, Classification and Staging of Middle Ear Cholesteatoma" was formally presented at the 10th International Conference on Cholesteatoma and Ear Surgery in Edinburgh, June 5-8, 2016...

This article describes the aberrant course of the internal carotid artery (ICA) through the middle ear as an extremely rare vascular anomaly. On the basis of a case report, the findings of magnetic resonance imaging, computed tomography imaging, and especially color-coded duplex sonography are presented. The diagnosis of an aberrant ICA is important to avoid severe surgical complications of a retrotympanic mass as well as unnecessary diagnostic or therapeutic approaches in expectation of a stroke.

OBJECTIVES: Presence of aberrant internal carotid artery (ICA) in the tympanic cavity is a very rare case and therefore the diagnosis is a challenge. Here, the authors aimed to address the importance of the diagnosis since the intervention to the middle ear and implants is increasing in number and this condition may lead to life-threatening bleeding. METHODS: Between 2012 and 2016, among the patients referred to the authors' Radiology Department from the Department of Otolaringology for the evaluation of the temporal region for various indications, the authors reported this anomaly in 6 patients and multidetector computerized tomography of these 6 patients and magnetic resonance imaging of 2 were assessed in detail...

Here, we provide a literature overview of cases with protruding molding material for earplugs or hearing aids and subsequent required treatment, including our own cases. Patients at risk are those with impaired tympanic membranes or who previously underwent otologic surgery. Symptoms such as otalgia, tinnitus, and vertigo are alarming but do not always arise. In case of doubt, a CT scan is of additive value to prepare for adequate surgical removal and to limit potential damage. A stepwise approach for the clinician on how to address these challenging cases is presented, based upon the literature and our own experience...

Eustachian tube dysfunction is believed to be an important factor to cholesteatoma development and recurrence of disease after surgical treatment. Although many studies have described prognostic factors, evaluation methods, or surgical techniques for Eustachian tube dysfunction, they relied on the soft tissues of its structure; little is known about its bony structure-the protympanum-which connects the Eustachian tube to the tympanic cavity, and can also be affected by several inflammatory conditions, both from the middle ear or from the nasopharynx...

Introduced in the late 90s, the active middle ear implant Vibrant Soundbridge (VSB) is nowadays used for hearing rehabilitation in patients with mild to severe sensorineural hearing loss (SNHL) unable to tolerate conventional hearing aids. In experienced hands, the surgical implantation is fast done, safe and highly standardized. Here, we present a systematic review, after more than 15 years of application, to determine the efficacy/effectiveness and cost-effectiveness, as well as patient satisfaction with the VSB active middle ear implant in the treatment of mild to severe SNHL...

BACKGROUND: Middle ear adenoma with neuroendocrine differentiation (MEA-ND), also known as carcinoid tumor of the middle ear, is an extremely rare neoplasm, especially when located within the tympanic cavity. To the best of our knowledge, this represents the first pediatric case of a MEA-ND described in Europe. Excluding the present case, only three other pediatric cases of this disease have been published globally. CASE REPORT: We report on a 15-year-old female patient who presented with conductive hearing loss of the right ear...
