Purpose: A patient registration and real-time surgical navigation system and a novel device and method (Noctopus) is presented. With any tracking system technology and a patient/target-specific registration marker configuration, submillimetric target registration error (TRE), high-precise application accuracy for single or multiple anatomical targets in image-guided neurosurgery or ENT surgery is realized.

Methods: The system utilizes the advantages of marker-based registration technique and allows to perform automatized patient registration using on the device attached and with patient scanned four fiducial markers.

Total spiking probability edges: A cross-correlation based method for effective connectivity estimation of cortical spiking neurons.

Background: Connectivity is a relevant parameter for the information flow within neuronal networks. Network connectivity can be reconstructed from recorded spike train data. Various methods have been developed to estimate connectivity from spike trains.

Sonority's Effect as a Surface Cue on Lexical Speech Perception of Children With Cochlear Implants.

Objectives: Sonority is the relative perceptual prominence/loudness of speech sounds of the same length, stress, and pitch. Children with cochlear implants (CIs), with restored audibility and relatively intact temporal processing, are expected to benefit from the perceptual prominence cues of highly sonorous sounds. Sonority also influences lexical access through the sonority-sequencing principle (SSP), a grammatical phonotactic rule, which facilitates the recognition and segmentation of syllables within speech.

Spike-contrast: A novel time scale independent and multivariate measure of spike train synchrony.

Background: Synchrony within neuronal networks is thought to be a fundamental feature of neuronal networks. In order to quantify synchrony between spike trains, various synchrony measures were developed. Most of them are time scale dependent and thus require the setting of an appropriate time scale.

Objectives/hypothesis: This feasibility study was designed to show the preliminary safety and efficacy of targeted hypoglossal neurostimulation (THN), and to identify baseline predictors of successful therapy.

Study Design: Open-label, prospective, multicenter, single-arm cohort study, conducted at seven centers in the U.S.

Induction of single-sided deafness in the newborn rat and its consequence for cochlear nucleus volume development.

Aim of this study was to induce a single-sided deafness (SSD) in rats before hearing onset. Rats were operated at postnatal day 10 by approaching the tympanic cavity along a retroauricular path without manipulating ossicles or tympanic membrane. The ototoxic aminoglycoside neomycin was injected intracochlearly through the round window membrane on one side.

The pattern of Fos expression in the rat auditory brainstem changes with the temporal structure of binaural electrical intracochlear stimulation.

The immediate-early-gene c-fos with its protein product Fos has been used as a powerful tool to investigate neuronal activity and plasticity following sensory stimulation. Fos combines with Jun, another IEG product, to form the dimeric transcription factor activator protein 1 (AP-1) which has been implied in a variety of cellular functions like neuronal plasticity, apoptosis, and regeneration. The intracellular emergence of Fos indicates a functional state of nerve cells directed towards molecular and morphological changes.

Speech Perception Outcomes after Cochlear Implantation in Children with GJB2/DFNB1 associated Deafness.

Background: Cochlear implants (CI) for the rehabilitation of patients with profound or total bilateral sensorineural hypoacusis represent the initial use of electrical fields to provide audibility in cases where the use of sound amplifiers does not provide satisfactory results.

Aims: To compare speech perception performance after cochlear implantation in children with connexin 26-associated deafness with that of a control group of children with deafness of unknown etiology.

Study Design: Retrospective comparative study.

Laryngotracheal stenosis and restenosis. What has the influence on the final outcome?

The aim of this study is to analyze the impact of various parameters on the course and treatment outcome in patients with laryngotracheal stenosis and recurrent stenosis. Two groups of patients were compared: Group I included 29 patients with primary stenosis, and Group II included 22 patients with recurrent stenosis. The most frequent etiological factor for the development of stenosis was prolonged endotracheal intubation (79.

Traumatic dislocation of the incudostapedial joint repaired with fibrin tissue adhesive.

We present a case of traumatic dislocation of the incudostapedial joint (ISJ) and a simple method for controlled application of the glue using commercial fibrin tissue adhesive. A 26-year-old female presented to our ENT clinic for hearing impairment to her left ear 2 months after a head trauma due to a motorcycle accident. The audiogram revealed a 40- to 50-dB HL conductive hearing loss with a notch configuration in bone conduction curve on the left ear.

Transient evoked otoacoustic emissions in young children with otitis media with effusion before and after surgery.

Objective: Otitis media with effusion (OME) is one of the commonest causes of acquired hearing loss in children with increasing incidence. In young children the diagnosis is restricted to clinical trials and tympanometry whereas evaluation of the auditory function is impossible due to noncompliance during pure tone audiometry. For this purpose, measurement of otoacoustic emissions, especially transient evoked ones (TEOAE), can be applied.

Surgical treatment of primary tracheal dyskinesia in a 14-month-old child--case report.

The primary form of tracheal dyskinesia in early childhood is a rare congenital malformation of unknown origin. The degree of the posterior membranous tracheal wall involvement determines the intensity of obstruction and the severity of the clinical picture. The aim of this paper is to present a case of a 14-month-old child with severe tracheal dyskinesia that required surgical treatment.

APSCI panel discussion I: imaging and surgical issues.

This is a short overview on imaging techniques in pre-, peri- and postoperative evaluation of cochlear-implant patients. Surgery techniques are described as well as possible complications and how to avoid them.

Psychic stress and quality of life in parents during decisive phases in the therapy of their hearing-impaired children.

Objective: This study was performed to analyze psychic stress and quality of life in the parents of children with hearing impairment in the course of various phases of treatment.

Design: At three measuring points over a course of 12 months, the degree of parental stress and the quality of life was surveyed prospectively. In addition, the children's hearing and speech status was surveyed.

Singing and evil in visual art.

Surprisingly, singing and music sometimes are connected with poor or even lethal outcomes. One example is personified in the legend of Orpheus, who through the power of his songs, succeeded in leading the wild Thracians into the Greek religion. This did not save him, however, from being murdered by Thracian women probably because of his paedophilic tendency.

Parenting stress and parental bonding.

Attachment experiences are thought to be important because of their implications for later development. The authors' aim with the questionnaire-based study was to investigate the differences between recalled parental bonding regarding 4 types of maternal and paternal bonding with respect to experienced parenting stress caused by child characteristics, parent attributes, and life events under the consideration of the child's gender and age. The authors gathered parental bonding behavior data with the German version of the Parental Bonding Instrument (PBI).

Reconstructive methods in hearing disorders - surgical methods.

Restoration of hearing is associated in many cases with resocialisation of those affected and therefore occupies an important place in a society where communication is becoming ever faster. Not all problems can be solved surgically. Even 50 years after the introduction of tympanoplasty, the hearing results are unsatisfactory and often do not reach the threshold for social hearing.

Impact of impaired nasal breathing on sleep-disordered breathing.

Objective: The role of the nose and its importance in the development and severity of sleep-disordered breathing (SDB) is still a matter of discussion. In the first part of this study, often-controversial data and theories about the nose are reviewed concerning its influence on the pathophysiology of SDB and to interpret certain clinical findings connected with impaired nasal breathing. In the second part, the effectiveness of some nonsurgical and surgical therapies is evaluated.

Receptive and expressive language skills of 106 children with a minimum of 2 years' experience in hearing with a cochlear implant.

Objective: The aim of the study was to assess the speech development of children with at least 2 years' hearing experience with a cochlear implant (CI).

Methods: One hundred and six children were tested, all of whom had used the CI for at least 2 years. Receptive and expressive language development were tested using the scales of early communication skills for hearing-impaired children after Geers and Moog and the Reynell developmental language scales III.

Investigating quality of life and coping resources after laryngectomy.

Surgical procedures and in particular laryngectomy can become a life-saving treatment for patients with laryngeal or hypopharyngeal cancer, but can result in permanent damage. Clinical observation suggests that patients vary considerably in their ways of dealing with this new situation and in their ability to cope. The aim of our interdisciplinary group was to investigate the quality of life of laryngectomy patients and learn about their perceptions, situation and coping mechanisms.
