Chronic Sinusitis Leads to Sinolith Formation in Maxillary Sinus – A Rare Case

Maxillary antrolith is a mineralized mass found very rarely in the maxillary sinus formed by exogenous or endogenous origin [1,2]. These mineralized bodies have been variously described as rhinoliths, antral rhinoliths, antral stones, antral calculi, antroliths, sinoliths, maxillary sinus stones and antrorhinoliths. The maxillary sinus is covered by ciliated pseudostratified columnar epithelium which is required for secretion of mucous [3,4]. Its function depends on the ostium opening, cilia and secretion quality and blockage of that normal drainage causes sinusitis. Acute sinusitis when not treated could become chronic, when the recurrent episodes occur for more than 3 months. This longstanding chronic sinusitis leads to chronic inflammation associated with poor sinus drainage, deposition of salts and enzymatic activities of bacterial pathogens are needed for the formation of an antrolith [5]. The purpose of this article is to report, a case of maxillary sinus sinolith which is the complications of chronic maxillary sinusitis.
