It is stone formation in the nasal cavity. A rhinolith usually forms around the nucleus of small exogenous foreign body, blood clot or inspissated secretion by slow deposition of calcium and magnesium salts. Over a period of time, it grows into a large, irregular mass which fills the nasal cavity and then may causes pressure necrosis of the septum or lateral wall of nose.
Rhinoliths are more common in adults,its common presentation is unilateral nasal obstruction and foul smelling discharge which is very often bood-stained. Frank epistaxis and neuraligic pain may result from ulceration of the surrounding mucosa.
On examination,a grey,brown or greenish-black mass with irregular surface and stony hard feel is seen in th nasal cavity between the spetum and turbinates. It is often brittle and portion of it may break off while manipulating. Sometimes it is surrounded by granulations.
They are removed under general anasethesia. Most of them can be removed through anterior nares. Large one need to be broken into pieces before removal. Some, particular hard and irregular ones, require lateral rhinotomy
Adhesion formation between the nasal septum and turbinates by scar tissue is often the result of injury to opposing surface of nasal mucosa. This has to be surgically removed.
