Summary
Normal nasal symptoms are occasional, momentary stuffy nose, and infrequent sneezing or nose blowing. This study redefines normal nasal symptom criteria for accurate rhinitis diagnosis and treatment evaluation.
Area of Science:
- Otolaryngology
- Allergy and Immunology
- Rhinology
Context:
- Nasal symptoms like sneezing and stuffy nose are common in allergic and nonallergic rhinitis.
- Differentiating these symptoms from those in a normal nose is crucial for accurate diagnosis and treatment assessment.
- Current diagnostic criteria for normal nasal symptoms require refinement.
Purpose:
- To establish objective criteria for defining a normal nose based on symptom frequency and intensity.
- To propose revised grading for nasal symptoms in individuals without rhinitis.
- To inform the development of improved rhinitis diagnostic and treatment normalization standards.
Summary:
- A study surveyed 235 individuals without nasal symptoms and 54 patients with normal noses diagnosed by otolaryngologists.
- Results indicated that normal nasal symptoms include none or occasional, momentary stuffy nose, and infrequent sneezing/nose blowing (<5 times/day).
- Itchy nose and postnasal drip occurred in 30% and 25% of participants, respectively, and were typically less than 4 days per week.
Impact:
- Provides a clearer definition of normal nasal symptoms, aiding in the diagnosis of rhinitis.
- Facilitates more accurate grading of rhinitis severity.
- Establishes a benchmark for assessing treatment effectiveness and normalization of nasal symptoms.
