INTRODUCTION In the last decade tonsillotomy has come into vogue again, whereas the number of tonsillectomies is decreasing rapidly. Currently, most tonsils are reduced by utilise electrosurgery, radiofrequency or carbon dioxide laser. However, it is not clear whether radiofrequency tonsillotomy is as effective as laser or other surgical techniques in(More)
BACKGROUND Depending on age and gender up to 60 % of the population snore regularly. As simple snoring is more a social than a medical problem, unlike OSAS, CPAP-therapy or multilevel surgery are not appropriate therapies for snoring. But alternative therapies, such as laser-assisted uvulopalatoplasty (LAUP) or uvulopalatopharyngoplasty (UPPP) address(More)
INTRODUCTION The therapy of choice in the treatment of pediatric obstructive sleep apnea syndrome (OSAS) consists of tonsillectomy or tonsillotomy combined with adenoidectomy. While tonsillectomy unfortunately has a notable risk of secondary hemorrhage and postoperative pain, tonsillotomy is safer and less painful for children. The effect of both surgical(More)
BACKGROUND Nonallergic rhinitis with eosinophilia syndrome (NARES) constitutes a rare nasal condition characterized by a chronic, eosinophilic inflammation. Patients' major complaints constitute nasal congestion and rhinorrhea. Obstructive sleep apnea syndrome (OSAS) is a potentially life-threatening condition characterized by recurrent episodes of(More)
Laser-assisted surgery is a valid option for the treatment of respiratory sleep disorders and complements established therapies. Laser-surgery of the inferior turbinates can improve nasal obstruction and amend or eliminate primary snoring. LAUP is as well an ambulant therapeutic method for snoring, but it is leading to strong post-operative pain and should(More)
OBJECTIVES To examine whether medical history and nasopharyngeal examination are useful for predicting obstructive sleep apnea syndrome (OSAS) and to compare these findings with those of the gold standard, polysomnography. DESIGN Patients underwent polysomnography recordings for 2 nights and an otorhinolaryngologic examination, including flexible(More)
Obstructive sleep apnea syndrome (OSAS) is a condition characterized by recurrent episodes of obstruction of the upper airway. The aim of this study was to evaluate whether nasal obstruction due to allergic rhinitis constitutes a risk factor for OSAS. Patients (n = 119) presenting typical symptoms of sleep apnea were tested for OSAS using polysomnography.(More)
OBJECTIVES Sleep at extreme altitudes is characterized by the repetitive occurrence of central apneas that in some cases may lead to a marked decrease in arterial oxygen saturation. During the Ludwig Maximilians University Expedition to Mt. Everest (MedEx 2006), nocturnal polygraphic recordings were made at different altitudes and included the first(More)
BACKGROUND The influence of nasal obstruction on sleep associated breathing disorders (SABD) and the controversial effects of surgical treatment are discussed. RESULTS Complete nasal obstruction caused by nasal packing increases SABD, but varies from patient to patient and depends on age and individual anatomy. Especially patients with preexisting(More)
