The sensation of a popping or clicking sound coming from the nose or the surrounding facial area is a common, yet often perplexing, experience. Although this feeling may be compared to cracking a knuckle, the two actions involve entirely different anatomical structures and mechanics. A knuckle pop is related to joint fluid and pressure changes, while the sound in the nasal area comes from the movement of soft tissues, air, and fluids. Understanding the source of this sound helps determine if it is a benign occurrence or a sign of a potential issue.
The Anatomy Behind the Nasal Sound
The sounds perceived as a “pop” or “click” in the nose most frequently originate from the movement of air and fluid within the nasal passages and paranasal sinuses. These sounds are not the result of a joint being intentionally manipulated, as the nose is primarily structured by cartilage and bone, not synovial joints. When pressure is applied to the nose, air bubbles can get momentarily trapped and then released within the thick mucus lining the sinus cavities, which produces a crackling noise.
The nasal septum, the dividing wall of the nose made of cartilage and thin bone, can also be a source of noise. If the cartilage has experienced past trauma or is naturally hypermobile, a shearing movement between cartilage segments can create a clicking sound when pressed. Furthermore, the nasal turbinates, which are bony structures covered by spongy mucous membranes, can swell and shift due to inflammation. The sound of sticky mucus momentarily adhering and then releasing from the turbinate walls can also result in an audible click.
Safety and Risks of Forcing a Pop
Intentionally trying to “pop” or manipulate the nose to replicate this sensation is generally not recommended, especially if it involves forceful pressure or movement. Unlike the joints in the hands, the delicate structures of the nose are not designed to withstand routine, forceful manipulation. The sound itself is typically incidental to movement or pressure regulation, not a sign of necessary pressure release.
Forcing a pop can irritate the sensitive mucosal lining of the nasal passages, which may increase the risk of a nosebleed. More concerning is the potential for damage to the underlying cartilage or the introduction of bacteria. Aggressive manipulation has led to a septal hematoma, which is a collection of blood under the lining of the septum.
Forceful blowing or pushing on the nose can also transmit high air pressure into the Eustachian tubes, which connect the back of the nose to the middle ear. This can result in a painful ear pop, and may force infectious fluid from the sinuses into the middle ear, potentially leading to an ear infection. The practice of trying to generate a pop should be avoided to protect the integrity of the nasal structure and connected systems.
When Nasal Sounds Are a Concern
While many nasal pops and clicks are benign, occurring due to simple mucus movement or minor pressure shifts, certain accompanying symptoms warrant medical attention. If the nasal sound is persistent or accompanied by pain, visible swelling, or difficulty breathing, consultation with a healthcare provider is advised. These symptoms could indicate an underlying structural issue or infection.
A sound that is chronic and associated with symptoms like facial pain, thick nasal discharge, or decreased sense of smell could be a sign of chronic sinusitis. Similarly, a noticeable change in the sound or its frequency following a traumatic injury should be evaluated for a potential septal fracture or severe deviation. A medical professional can determine if the sound is related to conditions such as nasal polyps, a deviated septum, or chronic inflammation.
