Silent Sinus Syndrome: A Case of Sinking Eyeball

Abstract

The first case of maxillary sinus opacification and atelectasis was reported by Montgomery in 1964 [1]. It was only after 30 years that the term silent sinus syndrome was coined by Soparkar [2]. Silent sinus syndrome is also called as imploding antrum, chronic maxillary atelectasis. Silent sinus syndrome is a condition characterized by asymptomatic, spontaneous enophthalmos and hypoglobus with characteristic clinical and radiographic features, including ipsilateral maxillary sinus atelectasis or hypoplasia [2].
