It is not possible to blow cartilage out of one’s nose. The structures within the nose are firmly attached and not designed to be expelled through forceful exhalation. This common misconception often arises from discomfort or unexpected sensations during vigorous nose blowing.
The Structure of Nose Cartilage
The nose is supported by a framework of bone and cartilage, giving it shape and maintaining open nasal passages. A significant part of this framework consists of hyaline cartilage, a flexible yet dense connective tissue. The main cartilaginous components include the septal cartilage, which forms the nasal septum separating the nostrils, and the alar cartilages, which shape the nostrils themselves. The septal cartilage is a flat, quadrilateral piece that fits between the ethmoid and vomer bones, extending from the nasal bones to the alar cartilages. The alar cartilages are flexible structures that maintain the patency of the nostrils. These cartilages are not loose pieces; they are securely connected to surrounding bone and fibrous tissues, forming a robust and integrated structure within the nasal cavity.
How Blowing Your Nose Works
Blowing one’s nose involves a forceful exhalation of air through the nasal passages to clear mucus and debris. This action is typically performed to alleviate congestion or remove irritants. While the force generated can be considerable, it is directed at expelling liquid mucus, not solid anatomical structures. Studies indicate that the pressure generated during nose blowing can be significant, sometimes reaching up to 1.3 pounds per square inch, which is considerably higher than during sneezing or coughing. Despite this pressure, the firm attachment of nasal cartilages to the bone and other tissues prevents their dislodgement. The mechanics are designed to propel secretions out, not to dismantle the nasal structure.
What Can Happen When You Blow Too Hard
While expelling cartilage is not a risk, forceful nose blowing can lead to other issues. One common consequence is a nosebleed, or epistaxis, which occurs when small, delicate blood vessels lining the nasal passages rupture from the pressure. The nasal lining is rich in tiny blood vessels, making them susceptible to irritation and bleeding, especially with dry air or frequent blowing. Excessive force can also push mucus and air into the sinuses or Eustachian tubes, which connect the middle ear to the back of the throat. This can increase pressure in the sinuses, potentially leading to discomfort, headaches, or even sinus infections if bacteria are forced into the cavities. Pressure changes can also cause ear pain, a feeling of fullness, or, in rare instances, a ruptured eardrum.
When to Seek Medical Help
It is advisable to seek medical attention if symptoms persist or worsen after forceful nose blowing. Consult a doctor for severe or prolonged nosebleeds that do not stop after 10-15 minutes of direct pressure, or if they occur frequently. Intense or persistent ear pain, changes in hearing, or a feeling of blockage in the ears following forceful blowing warrant professional evaluation. Other indicators for medical consultation include severe or worsening sinus pain, pressure, or discharge that suggests an infection, especially if accompanied by fever. Any unusual discharge, such as clear fluid following head trauma that might suggest a cerebrospinal fluid leak, also requires immediate medical assessment. Prompt medical attention helps address potential complications and ensures appropriate care.
