title: [Inpatient Salivary Gland Surgery in Germany: A DRG-Based Nationwide Analysis, 2007-2011].
abstract: BACKGROUND
  This is the first population-based analysis of inpatient salivary gland surgery across Germany.
  
  
  METHODS
  Nationwide Diagnosis-Related Groups (DRG) statistics for 2007 to 2011 were analyzed regarding indications for salivary gland surgery based on ICD-10 codes. Age specific surgery rates were calculated for both sexes.
  
  
  RESULTS
  Inpatient salivary gland surgical rates in 2007-2011 amounted for incisions (OPS [Classification of Operations and Procedures] code 5-260) 1.43 per 100 000 population, for excisions (5-261) 2.06 per 100 000, for salivary gland resections (5-262) 2.06 per 100 000, and for external incisions (5-270) 0.43 per 100 000. Regarding the mentioned four OPS codes, the surgical rates for benign tumors accounted to 10.08 per 100 000, for sialadenitis (without sialoliths) to 4.00 per 100 000, for malignant tumors to 3.90 per 100 000, and for sialolithiasis to 2.09 per 100 000. The increase of surgical rates from 2007 to 2011 was significant for malignant and benign tumors as well as for salivary stones. The surgical rates were highest for patients>60 years.
  
  
  CONCLUSIONS
  Especially surgery for malignant tumors was more frequent than expected. In spite of the introduction of minimal invasive technique the rates for salivary gland resections in case of sialadenitis or sialolithiasis still seem to be high.
