Study design and patient inclusion
This was a retrospective analysis of prospectively collected data on 28
patients with prestyloid tumors undergoing surgery at our center
([removed for blind peer review]) from February 2015 to February
2020. All patients underwent a clinical examination, magnetic resonance
imaging (MRI) and computed tomography (CT). A fine-needle aspiration was
taken transorally or transcervically.8
The use of the data base was approved by the hospital ethics committee
([removed for blind peer review]) and all individuals included in
the study provided their signed informed consent.
