Results of anationwide survey on the treatment of salivary gland diseases in German hospitals

Abstract

Salivary gland diseases are an important part of the work of ENT physicians in hospitals. The treatment strategies depend, among other things, on the doctrine at the respective location. The aim of this questionnaire-based study was to assess the current diagnostic workup and therapeutic strategies for salivary gland diseases in German otorhinolaryngology departments. Asurvey was performed using a 25-question online questionnaire sent to all German otorhinolaryngology department directors. The questionnaire was answered by92 of 175otorhinolaryngology departments (52.6%). In the diagnosis of salivary gland tumors, adominance of sonography and MRI was shown. Fine- and core-needle aspiration were not performed by more than 50% of the clinics. The dominant technique for parotidectomy was under microscopic control (82%). In 99% of clinics, EMG was used during resection of the parotid gland for intraoperative monitoring of the facial nerve. There was atrend towards performing partial parotidectomies (85%), lateral parotidectomies (70%), and extracapsular dissections (57%) for benign tumors of the parotid gland. The treatment concepts for malignant tumors were inconsistent. In particular, the treatment strategy and extent of surgery for benign and malignant salivary gland tumors differed depending on location. The choice of palliative (drug) therapy was also diverse. Prospective multicenter studies could help to develop evidence-based treatment strategies.
