|Beitragstitel||Trigeminal Endonasal Sensitivity - an Outcome Predictor for Septoplasty|
Background. Different studies already concluded a meaningful role of trigeminal sensitivity
for the perception of nasal airflow and the impression of a “patent nose“. The aim of this study was to examine whether trigeminal sensitivity predicts patients’ satisfaction after septoplasty.
Material and Methods. All patients planned for primary septoplasty or functional septorhinoplasty with turbinoplasty were asked to participate in this prospective study. Before and 6 weeks after surgery standard preoperative examinations (acoustic rhinometry and Sniffin’ Sticks 12 test), an evaluation of nasal obstruction on a visual analogue scale (VAS) and the trigeminal lateralisation test were performed.
Preoperative lateralisation test scores were then plotted against mean VAS change scores, representing on the one hand endonasal trigmenial sensitivity and on the other hand subjective improvement. Additionally, biopsies were taken during surgery and TRPV1 mRNA expression was measured by PCR.
Results. A significant correlation of trigeminal perception and the sensation of nasal obstruction was found (r=0.40, p=0.03). Furthermore, high TRPV1 mRNA expression was linked with good postoperative VAS scores.
Conclusion. Endonasal trigeminal sensitivity is directly linked with subjective outcome. With this preoperative assessment of trigeminal sensitivity, patients could be selected more appropriately and the rate of satisfaction could be improved. Therefore, patients with low trigeminal sensitivity should undergo septoplasty only after thorough counselling.
