A nasal stone is a mineralized mass or stone that is formed within your nasal cavity.
The nasal stone is often around a retained foreign body or a blood clot.
A nasal stone is also known as rhinoliths which typically forms when calcium and magnesium salts deposit and harden around a nidus which is a small object or area within your nasal cavity.
The nidus can be a retained foreign body such as a small object, seed or even piece of paper or a blood clot or natural secretion.
The symptoms of a nasal stone or rhinoliths include nasal obstruction, foul smelling nasal discharge and pain or discomfort in your nose and surrounding areas.
Nasal stones are often discovered during an ear, nose and throat exam or even incidentally during radiological exams such as CT scans and X rays.
Treatment for nasal stones is often the removal of the nasal stones surgically.
In some cases some people may not experience any symptoms of the nasal stones and be unaware that they have the nasal stones, especially in the early stages.
Nasal stones are found frequently as incidental findings during rhinoscopy's and appear as irregular, hard dark masses with greenish foul smelling crusts all around them.
X rays and CT scans can help with diagnoses and any complications of the nasal stones.
