PROBLEMS ADDRESSED Despite their abundant spread, mobile phones are suspected by a major share of the population to cause adverse effects on health and welfare. The ear as the sense organ next to the individual device has rarely been investigated for short-term effects in this regard. In a previous article, we could not prove any impact on the vestibular(More)
CONCLUSIONS The results of this study show that in clinical practice it will not be easy to diagnose tonic contractions of the tensor tympani muscle and only a combination of findings will be helpful. Based on these experimental results a clinical study will be started which should clarify the diagnostic relevance of indicators of tonic tensor muscle(More)
OBJECTIVES Pulsating electromagnetic (EM) radiation emitted by mobile phones is often incriminated for causing tissue alterations by caloric effects. In particular, the eye and the ear were regarded as possible "hot spots," with heating up to 1 degree C, in which EM radiation might have negative effects. If so, these temperature increments should be large(More)
CONCLUSION By means of a direct, though non-invasive experiment on healthy humans we could demonstrate that middle ear (ME) pressure decreases when the eustachian tube (ET) does not open. Thus with a very simple method the basic theory of continuous gas loss from the ME into the circulation and the replenishment of the loss through the ET could be(More)
BACKGROUND It is the subject of this study to investigate the biological effect of the HF radiation produced by the Global System for Mobile Communications-( GSM)-mobile phone on the inner ear with its sensors of the vestibular and auditive systems. METHODS/PATIENTS Thermographic investigations made on various model materials and on the human temporal(More)
OBJECTIVE To prove the feasibility of recording stapedius reflexes by bipolar electromyography intra-operatively during cochlea implant via a bipolar hook needle electrode. STUDY DESIGN Prospective study. SETTING Tertiary referral center. PATIENTS Adults receiving a MED-EL cochlear implant. INTERVENTION Diagnostic. MAIN OUTCOME MEASURES Stapedius(More)
OBJECTIVE Aim of this paper is to prove the applicability of intra-operative recordings of auditory brainstem responses during cochlear implantation. METHODS The clinical practicability of intra-operative monitoring of hearing thresholds (Notched-Noise BERA, Amplitude Modulation Following Response [AMFR]) is presented in the respective case. The(More)
Healing and integration of a cochlear implant is largely influenced by good blood circulation in the covering skin, which, on the other hand, is closely correlated to skin temperature. Measuring superficial flap temperatures by thermography is an easy way to get some clues about the corresponding blood supply. These data should allow some implications for(More)
Bei CI-Versorgung eines Ohrs mit Tieftonrestgehör sollte die cochleäre Funktion für die Möglichkeit einer elektrisch-akustischen Stimulation (EAS) erhalten bleiben. Neben möglichst atraumatischer Elektrodeninsertion sollte auch das akustisch-mechanische Trauma bei der Cochleostomie minimiert werden. Ausgehend von Felsenbeinversuchen stellten wir die(More)
OBJECTIVES To assess the reliability of visually assessed thresholds of the electrically elicited stapedius reflex, recorded during cochlear implant surgery, compared with intra-operative tympanometric threshold assessment. Intra-operatively recorded electrically elicited stapedius reflex thresholds vary considerably, and differ from those measured(More)
