To the authors' knowledge, this is the first report of a new, simple, and inexpensive minimally invasive technique that proved to be at least partially successful in the treatment of sialolithiasis in cases refractory to other therapies. The technique also seems to be suitable as a primary treatment approach.

The German Society of Otorhinolaryngology, Head and Neck Surgery recently has released the abbreviated version of its scientific guideline "ENT-specific therapy of obstructive sleep apnoea (OSA) in adults", which has been updated in 2015 and can be found online at the Association of the Scientific Medical Societies (Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften, AWMF). A summary of the main recommendations is provided in this revised English version. All recommendations are based on a systematic literature research of articles published up until March 2014. Literature research followed the Cochrane Handbook for Systematic Literature Research to create Guidelines published by the German Cochrane Centre. Studies were evaluated with respect to their scientific value according to the recommendations of the Oxford Centre for Evidence-based Medicine, and grades of recommendation are provided regarding each intervention.

Although patients felt relieved after surgery since their nasal breathing problem was solved, the results with respect to AHI, EDS, and sleep pattern were unexpected. Perhaps these findings can be explained by surgical alteration of nasal receptors or by a postoperative switch from oral to nasal nocturnal breathing.

NCPAP therapy has a number of different side effects in the head and neck. These side effects are seen frequently. Prospective analysis must show whether there are correlations between the intensity and frequency of side effects and the duration of therapy, and whether technical improvements (quality of masks, noise reduction, humidifiers) are able to reduce the frequency of side effects.

The present S2e-guideline is an update of the former S2e-guideline "treatment of obstructive sleep apnea in adults". The update was performed on behalf of the German Society for Otorhinolaryngology, Head and Neck Surgery by its Sleep Medicine Task Force. The long version of the guideline is valid from 5.9.2015 to 5.9.2020 and has been available (guideline No. 017-069) since November 2015 on the official AWMF website.The subsequently presented short version of the guideline summarizes the essentials in a legible way. For further information, please refer to the long version.
