BackgroundMicroaggressions are subtle verbal or behavioral insults (intentional or unintentional) that typically convey negative or hostile attitudes towards marginalized groups. We aim to study microaggressions and workplace culture amongst European otolaryngologist -head and neck surgeons (E-OTOHNS). The perception of "differential treatment" based on individual traits was used as a proxy for microaggressions.

Purpose: To investigate the subjective effect of office-based blue laser therapy for inferior turbinate hypertrophy in patients with nasal obstruction.

Methods: Patients with nasal obstruction who underwent office-based blue laser for the inferior turbinate hypertrophy between October 2022 and December 2023 were included in the study. The two outcome measures used to gauge the improvement in nasal obstruction and success of surgery were the Nasal Obstruction Symptom Evaluation (NOSE) scale and the Visual Analogue Scale (VAS).

Article Synopsis
  • - Young European otolaryngologists (OTOs) were surveyed about their views on transoral robotic surgery (TORS), revealing a 26% response rate from participants.
  • - Key barriers to TORS adoption included robot availability (73%), high costs (69%), and insufficient training (37%), while the main advantages were better surgical visibility (64%), reduced hospital stays (62%), and improved post-op outcomes (61%).
  • - Despite these challenges, 67% of TORS practitioners felt adequately trained, and there was an overall positive perception of TORS among young OTOs, especially for specific cancer types and conditions.
