Radiation therapy is an established modality in the treatment of head and neck cancer patients. Compromised wound healing in irradiated tissues is a common and challenging clinical problem. The pathophysiology and underlying cellular mechanisms including the complex interaction of cytokines and growth factors are still not understood completely. In this(More)
OBJECTIVE To investigate in vertigo patients in routine practice to what extent a rapid and straightforward triple bedside test (spontaneous nystagmus, head-shaking nystagmus, and the head impulse test) can predict a normal result on caloric testing. STUDY DESIGN Prospective, single-blind, diagnostic study. SETTING Tertiary referral center. PATIENTS(More)
Sedation or anesthesia is often necessary in pediatrics when magnetic resonance imaging is performed. This anesthesia outside of the operation room combines specific requirements and risks. Ferromagnetic foreign bodies are a clear contraindication for magnetic resonance imaging due to the high magnetic field within the scanner. However, insertion of various(More)
BACKGROUND The inflammatory response clinically observed after radiation has been described to correlate with elevated expression of cytokines and adhesion molecules by endothelial cells. Therapeutic compensation for this microvascular compromise could be an important approach in the treatment of irradiated wounds. Clinical reports describe the potential of(More)
OBJECTIVE The underlying pathology of sudden sensorineural hearing loss (SSNHL) is still not completely understood. Inflammatory and vascular factors are part of the present discussion. The aim of this study was to learn more about the possible role of adhesion molecules and cytokines in patients with SSNHL. These molecules are thought to contribute to(More)
Secondary cleft rhinoplasty represents a particular surgical challenge. The authors have identified the deficit in skeletal projection of the cleft-sided piriform rim as an important contributor to the pathology. A graft is described to augment the piriform crest on the cleft side. This foundation graft is suture fixated to the piriform crest after complete(More)
Objective: Many tinnitus patients complain about difficulties regarding speech comprehension. In spite of the high clinical relevance little is known about underlying mechanisms and predisposing factors. Here, we performed an exploratory investigation in a large sample of tinnitus patients to (1) estimate the prevalence of speech comprehension difficulties(More)
External radiation seems to be associated with increased amounts of cytokines and other cellular modulators. Impaired microcirculation and fibrosis are examples of typical long term damage caused by radiotherapy. Adipose tissue-derived stem cells (ASC) are discussed to enhance wound healing, but their role in wounds due to radiotherapy is poorly understood.(More)
The aim of this study was to find out whether objective analysis of snoring sounds (sound pressure level and psychoacoustic parameters) correlates with the subjective rating by participants with respect to perceived annoyance and hence whether it is useful. 43 participants, aged 22-65 years with normal hearing, were asked to rate 60 snoring sounds from(More)
UNLABELLED BACKGROUND Aim of the present study was to evaluate the occurence of a round window membrane rupture and the effects of hearing restoration after exploratory tympanotomy and sealing of the round window (niche) in patients with unilateral sudden deafness. METHODS Retrospective analysis of patients' charts in a tertiary referral center. Charts(More)
