Summary
Cigarette smoking negatively impacts olfactory function, particularly in older adults undergoing chronic sinusitis surgery. While surgery can improve smell for many, smokers over 40 experienced persistent deficits in smell identification.
Area of Science:
- Otolaryngology
- Smell and Taste Disorders
Background:
- Chronic sinusitis often impairs olfactory function.
- Surgical interventions aim to restore sinonasal function and potentially improve olfaction.
Purpose of the Study:
- To evaluate the efficacy of surgical intervention for chronic sinusitis on olfactory function.
- To investigate the influence of cigarette smoking on olfactory ability in patients undergoing surgery.
Main Methods:
- Olfactory ability was assessed using the University of Pennsylvania Smell Identification Test (UPSIT).
- 37 patients (21-60 years) with chronic sinusitis underwent surgery.
- Preoperative and postoperative UPSIT scores were analyzed, considering age and smoking status.
Main Results:
- 64.5% of patients showed improvement in smell (≥4 point UPSIT increase) post-surgery.
- 31 patients had preoperative olfactory disturbance.
- Smokers over 40 years old exhibited significant preoperative and postoperative olfactory deficits.
Conclusions:
- Surgical intervention can improve olfactory function in many patients with chronic sinusitis.
- Cigarette smoking adversely affects olfactory ability, especially in older patients.
- Smoking cessation may be crucial for optimizing olfactory recovery after sinusitis surgery.
