Changing trends in the epidemiology and surgical treatment of benign parotid gland tumours: a 10-year retrospective comparison in a tertiary referral centre of southeast Bavaria.
Article in Head & face medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundBenign salivary gland tumors are in general rare. Pleomorphic adenomas (PA) and Warthin’s tumors (WT) make up to 90% of these tumors. Their epidemiology shows significant regional differences but also changes over time. In addition to that, new developments in the surgical approach, like extracapsular dissection (ED), have been introduced.
methodsWe retrospectively analyzed epidemiological and clinical data of 347 patients (184 male and 163 female) treated in the ENT-Department of the University Hospital of Regensburg in 2010/11 and 2020/21 and assessed their changes over time.
resultsWT is by far the most common benign tumor of the parotid gland, followed by PA and the age of diagnosis shows an increasing tendency. The hospitalization time showed a significant reduction after a period of ten years. Patients treated with ED are being hospitalized for a shorter period of time. Regular smokers tend to present more WT and are being diagnosed at younger age. Patients with WT have a higher body mass index (BMI) than other patients.
conclusionsOver the last decade, WT remained the most common benign parotid tumor in Southeast Bavaria, while the implementation of ED has potentially impacted clinical resource utilization coincide with reduced duration of inpatient hospitalization.
