Summary
Nasal mucosa blood flow (NMBF) is typically steady in healthy individuals but significantly decreases in patients with chronic rhinitis. This finding suggests NMBF measurement is a valuable tool for assessing treatment effectiveness in rhinitis.
Area of Science:
- Otorhinolaryngology
- Medical Physiology
- Biomedical Engineering
Context:
- Chronic rhinitis encompasses various inflammatory conditions affecting the nasal mucosa.
- Accurate assessment of nasal mucosal blood flow is crucial for understanding rhinitis pathophysiology.
- Existing methods for evaluating rhinitis may not fully capture microcirculatory changes.
Purpose:
- To investigate and quantify blood flow in the human nasal mucosa.
- To determine if nasal mucosa blood flow (NMBF) differs between healthy subjects and patients with chronic rhinitis.
- To explore the potential of NMBF measurement as a diagnostic and therapeutic evaluation tool for rhinitis.
Summary:
- Laser Doppler flowmetry was employed to measure NMBF at six points on the nasal mucosa in 108 healthy young adults and 89 patients with chronic rhinitis (including allergic and atrophic rhinitis).
- Data revealed that average NMBF is generally stable in healthy individuals.
- A significant decrease in NMBF was observed across all three types of chronic rhinitis studied.
Impact:
- NMBF measurement using laser Doppler flowmetry provides a quantifiable and objective method for assessing nasal mucosal circulation.
- The observed reduction in NMBF in chronic rhinitis patients suggests impaired microvascular function.
- This technique holds promise for monitoring treatment efficacy and disease progression in patients with various forms of rhinitis.
