Nasal Anatomy: Common Concerns and Breathing Issues

Inquiry Consultation

Dear Dr.
Zhou,
1.
The width of my left and right nostrils measures approximately 1 cm when measured horizontally, and about 1.2 cm at the widest diagonal point.
I do not experience nasal congestion or any other breathing difficulties.
I would like to ask you: Q1.
Are the sizes of my nostrils within the normal range for an average person? Q2.
Additionally, is there a correlation between nostril size and the volume of air inhaled? For instance, do individuals with smaller nostrils inhale less air and thus are more prone to hypoxia, or is there no relationship between nostril size and the amount of air inhaled?
2.
When I take a deep breath, my left nostril collapses and becomes smaller due to the suction, while my right nostril does not exhibit this behavior.
I have researched and it seems to be a case of unilateral "external nasal valve collapse." However, during normal breathing, neither nostril collapses; this only occurs when I inhale forcefully.
I would like to ask you: Q3.
Given my situation, do I need medical treatment, or is it sufficient to just observe? Q4.
Based on your experience and perspective, is "external nasal valve collapse" a common condition? Q5.
I tested for "external nasal valve collapse" by forcefully inhaling several times, which resulted in slight hypoxia and dizziness.
Could you explain the underlying principle? Is it possible to experience hypoxia and dizziness after forcefully inhaling several times in a short period?
Thank you, Dr.
Zhou.

Hello! Thank you for your detailed questions regarding nasal anatomy and related concerns. Let's address each of your queries systematically.

Q1: Are my nasal measurements within the normal range?
Based on your measurements, a width of approximately 1 cm for each nostril and 1.2 cm at the widest point is generally considered to be within the normal range for adults. Nasal anatomy can vary significantly among individuals, but these dimensions do not indicate any abnormalities.

Q2: Is there a correlation between nostril size and air intake?
The size of the nostrils can influence airflow, but it is not the sole determinant of how much air is inhaled. While larger nostrils may allow for greater airflow, other factors such as nasal passage structure, the presence of any obstructions (like polyps or deviated septum), and overall respiratory health play significant roles. Therefore, a person with smaller nostrils may not necessarily experience oxygen deprivation if their nasal passages are otherwise clear and functioning well.

Q3: Should I seek medical treatment for the nasal collapse during forceful inhalation?
The phenomenon you describe, where one nostril collapses during forceful inhalation, is known as "external nasal valve collapse." If this occurs only during intense inhalation and does not affect your normal breathing or daily activities, it may not require immediate medical intervention. However, if you experience discomfort, difficulty breathing, or if this condition worsens, it would be prudent to consult an ENT specialist for a thorough evaluation.

Q4: How common is external nasal valve collapse?
External nasal valve collapse is relatively common, especially among individuals who may have structural variations in their nasal anatomy. It can occur due to factors such as weakness in the nasal cartilage or excessive nasal tissue. While it may not be a widespread issue, it is not uncommon, particularly in individuals with a history of nasal trauma or surgery.

Q5: Can forceful inhalation lead to temporary hypoxia and dizziness?
Yes, forceful inhalation can lead to temporary hypoxia, especially if it causes a significant collapse of the nasal passages, limiting airflow. When you exert yourself to inhale forcefully, you may create a negative pressure that can lead to a reduction in airflow, resulting in less oxygen being delivered to your lungs. This can cause feelings of dizziness or lightheadedness due to decreased oxygen levels in the bloodstream. It’s essential to breathe normally and avoid excessive forceful inhalation to prevent such symptoms.

Additional Considerations
If you are experiencing any discomfort or persistent symptoms, it is advisable to consult with an ENT specialist. They can perform a thorough examination, including nasal endoscopy if necessary, to assess the structural integrity of your nasal passages and provide recommendations tailored to your specific situation.

In summary, while your nasal measurements appear normal and the collapse during forceful inhalation may not be a significant concern, it is essential to monitor your symptoms. If you notice any changes or if the situation worsens, seeking medical advice would be the best course of action. Maintaining good nasal hygiene and avoiding irritants can also help in managing any potential issues. Thank you for your questions, and I hope this information helps clarify your concerns!
