[Evaluation of polypectomy-related changes on olfactory function].

Area of Science:

• Otolaryngology
• Rhinology
• Sensory science

Background:

• Nasal polyposis frequently causes nasal obstruction.
• Nasal obstruction is associated with impaired olfactory function.
• Surgical intervention like polypectomy is a common treatment for nasal polyps.

Purpose of the Study:

• To evaluate changes in olfactory function after polypectomy.
• To compare postoperative olfactory function with preoperative status.
• To investigate the relationship between nasal polyposis, obstruction, and olfaction.

Main Methods:

• Olfactory function was assessed using the Elsberg-Levy method.
• Measurements were conducted on 25 patients preoperatively.
• Postoperative assessments were performed one month after polypectomy.

Main Results:

• Preoperatively, 18 patients exhibited higher odor thresholds, indicating reduced olfactory sensitivity.
• Postoperatively, 14 patients with hyposmia showed a decline in odor thresholds, signifying improved smell.
• The study observed a trend towards improved olfactory function post-polypectomy.

Conclusions:

• Olfactory function is significantly impacted by nasal obstruction due to nasal polyposis.
• Polypectomy demonstrates potential to enhance olfactory function in patients with nasal polyps.
• Olfactometry serves as a valuable tool for assessing nasal polyps during and after treatment.
