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...

The objective of the study was to improve the functional outcomes of the treatment in the patients presenting with chronic otitis media by means of the combined application of platelet-enriched plasma and the biologically compatible cyanacrylate-based glue for the fixation of the reconstructed auditory ossicular chain. The functional results of the surgery were evaluated within 1, 3, and12 months after the intervention making use of tonal threshold audiometry. It was shown that the use of the platelet-enriched plasma with its subsequent fixation by the biologically compatible cyanacrylate-based glue enhances stability of the implanted prosthetic elements, reduces the risk of their displacement during the postoperative period due to the formation of the cicatrical tissue between the structural components of the middle ear...

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...

INTRODUCTION: In Internet forums and other social media many reports regarding chronic headaches after cochlear implantation can be found. Although quite rare, there are also some reports in the literature. However, little is known regarding the true prevalence of headaches in persons who have undergone cochlear implant surgery. OBJECTIVES: The primary aim of this study was to investigate the 1-year prevalence of headache in patients having received a cochlear implantation ("cochlear implant group") in comparison with patients having undergone middle ear surgery ("surgery group") and persons with no history of head and neck surgery ("non-ear-nose-throat [ENT] group")...

Cone beam computed tomography (CBCT, syn. digital volume tomography = DVT) was introduced into ENT imaging more than 10 years ago. The main focus was on imaging of the paranasal sinuses and traumatology of the mid face. In recent years, it has also been used in imaging of chronic ear diseases (especially in visualizing middle and inner ear implants), but an exact description of the advantages and limitations of visualizing precise anatomy in a relevant number of patients is still missing. The data sets of CBCT imaging of the middle and inner ear of 204 patients were analyzed regarding the visualization of 18 different anatomic structures...

A number of methods to drive the round window (RW) using a floating mass transducer (FMT) have been reported. This method has attracted attention because the FMT is relatively easy to implant in the RW niche. However, the use of an FMT to drive the RW has been proven to produce low outputs at frequencies below approximately 1 kHz. In this study, a new tri-coil bellows-type transducer (TCBT), which has excellent low frequency output and is easy to implant, is proposed. To design the frequency characteristics of the TCBT, mechanical and electrical simulations were performed, and then a comparative analysis was conducted between a floating mass type transducer (like the FMT) and a fixed type transducer (like the TCBT)...
