[Value of sialendoscopy in German ENT-hospitals in 2016].

Objective: In 2009 a nationwide survey revealed that only 24 % of the German ENT-hospitals performed sialendoscopy. In 2016 the survey was repeated to reevaluate the actual ranking of sialendoscopy in Germany.

Material Und Methods: Again, the same questionnaire as in 2009 was sent to all German ENT-hospitals. It is a self-developed questionnaire including eleven questions. The results from 2009 and the new results from 2016 were matched with each other.

Results: The amount of hospitals performing sialendoscopy doubled and the number of interventions tripled. There were various reasons for denying sialendoscopy. Main reason was a lack of patients. No differences were seen in ambulant vs. inpatient interventions and the duration of sialendoscopy. Preoperative ultrasound was performed in all hospitals.

Conclusions: The survey reveals an increasing number of hospitals performing sialendoscopy and an increasing number of sialendoscopies. Simultaneously, some hospitals alleged a lack of patients. These facts could explain a development of specialized centers for obstructive sialadenitis and sialendoscopy. Meanwhile, further salivary gland diseases are treated with sialendoscopy. The preoperative diagnostic of choice is ultrasound. Sialendoscopy seems to be more and more established in German ENT-hospitals.
