[Sinusitis of dental origin]. / Die dentogene Sinusitis.

In recent years, an increasing number of dental infections of the maxillary sinus has been observed. A prerequisite for a bacterial infection of the maxillary sinus is the perforation of Schneider's membrane. Pathogenetically, the ostiomeatal unit is only secondarily involved due to the infection ascending from the maxillary sinus floor. Besides the anamnesis, imaging procedures are important, whereby the high-resolution CT and CBCT (cone beam CT) have a special task due to their three-dimensional resolution. A dental X-ray or a dental examination for diagnosis is not sufficient in many cases. Due to the anatomy, the molars in particular are to be regarded as the cause of dentogenic sinusitis. The germ spectrum is polymicrobial with a dominance of anaerobes. Therapeutically, we favour one-stage surgery with rehabilitation of the underlying process and functional sinus surgery. Functional sinus surgery can also make a significant contribution to the rehabilitation of inflammatory complications in implantology.

Diagnosis and treatment of snoring in adults--S1 guideline of the German Society of Otorhinolaryngology, Head and Neck Surgery.

INTRODUCTION: Snoring has received increased attention over the last years. Given its high prevalence and its impact on quality of life, diagnosis and treatment of snoring are of major importance. AIM OF THE GUIDELINE: This guideline aims to promote high-quality care by medical specialists for adults who snore. DIAGNOSTIC MEASURES: Before every intervention, a medical history, clinical examination and sleep test need to be performed. INTERVENTIONS: There is no need to treat snoring unless requested by the snorer. Invasive treatments should be selected with care; for surgical treatment, minimally invasive procedures are preferred. Weight reduction; the avoidance of sleeping pills, alcohol and nicotine; and a regular sleep-wake cycle can be recommended, although convincing evidence is lacking. Since currently, there is not enough evidence to confirm the effectiveness of muscle stimulation or other forms of muscle training, these treatments cannot be recommended. Snoring can be treated successfully with intraoral devices, but it is essential to select suitable subjects. Devices preventing sleep in the supine position can also be helpful in selected cases. The data on the success rates of surgical intervention are often limited to short-term follow-up studies, and not all interventions have been sufficiently evaluated. The techniques used to treat nasal obstruction in snorers are identical to those used for general nasal obstruction. Nasal surgery is only indicated when subjects complain about nasal obstruction. A significant amount of data is available for laser-assisted resection of excessive mucosa; however, resections can be performed with other tools. The efficacy of radiofrequency surgery at the soft palate has been documented in placebo-controlled trials. Soft palate implants can reduce snoring. Tonsillectomy or uvulopalatopharyngoplasty should be selected with care, especially as less invasive alternatives are available.
