Effects of septorhinoplasty on smell perception.

Purpose: To assess whether significant changes in smell perception occur after septorhinoplasty, and evaluate whether septum deviation, allergic rhinitis, and surgical technique affect postoperative smell perception.

Methods: Thirty-four patients (> 18 years old) awaiting septorhinoplasty were included, while those with previous severe hyposmia or anosmia were excluded. The participants self-assessed their smell perception using a 100-mm visual analogue scale (VAS), where 0 mm indicated the inability to smell and 100 mm indicated normal smell perception.
