Cholesterol granuloma in the paranasal sinuses is rare. It is more common in the mastoid antrum and temporal bone air cells in chronic middle ear disease. A case of bilateral maxillary sinus cholesterol granuloma that mimics chronic maxillary sinusitis is reported. This is the first reported case of cholesterol granuloma of the maxillary sinus in the Malaysian Literature.

BACKGROUND Several anatomical variations can lead to the inflammation of the paranasal sinuses; therefore, surgeons should be familiar with these variations and their impacts on the status of the paranasal sinuses. OBJECTIVES The present study aimed to determine the prevalence of Haller cells and its association with patients' sex and age. Furthermore, the relationships between the presence a...

OBJECTIVE Organized hematoma of the maxillary sinus can develop by means of organization of hematoma in the unaerated maxillary sinus. To our knowledge, this is only the second article describing organized hematoma in the maxillary sinus. MATERIAL AND METHODS We have observed eight cases of organized hematoma of the maxillary sinus recently and here we describe the clinical features (using CT...

Macaques (genus Macaca) are unique among cercopithecids in that they possess a maxillary sinus, and among anthropoids in that they demonstrate a relatively weak relationship between the size of this sinus and the cranium. To test the hypothesis that extrinsic factors may contribute to maxillary sinus size variation, a sample of 46 Japanese macaque (M. fuscata) crania from known localities were ...

Antral pathoses and anatomical variations increase the risk of surgical complications during a lateral window sinus augmentation procedure. Therefore, an understanding of maxillary sinus diseases and anatomies is imperative. In the first part of this article, common sinus diseases will be reviewed, which include acute/chronic rhinosinusitis, mucoceles, pseudocysts, retention cysts, and odontoge...

Nasopharyngeal carcinoma (NPC) may spread to the paranasal sinuses. This retrospective study describes the features of paranasal sinus involvement in NPC on computed tomography (CT) and magnetic resonance imaging (MRI). One hundred and fourteen patients with histologically proven NPC underwent staging with both CT and MRI. Maxillary sinus infiltration was demonstrated on MRI in 10 patients; sph...

The maxillary sinus augmentation procedure has been gaining more acceptance among dental professionals. The aim of this review article is to provide an update about various aspects of anatomy, physiology, and common pathological conditions of the maxillary sinus and their clinical relevance to the sinus augmentation procedure and subsequent implant placement.

Enophthalmos developed in a 44-year-old woman with history of respiratory infection but not of sinus disease. Sinus roentgenograms and MR revealed opacification of the right maxillary antrum, deviation of the nasal septum to the right, obstruction of the right osteomeatal complex, and diminished volume of the right maxillary sinus.

150 Maxillary sinus hypoplasia (MSH) is the underdevelopment of maxillary sinus antrum and it is usually associated with other anomalies, such as uncinate process and infundibular passage. Hypoplasia is classified into three: Type I is mild hypoplasia, normal uncinate and infundibulum; Type II is significant hypoplasia with hypoplastic or absent uncinate and pathological infundibular passage; T...

A very low incidence of complications of rehabilitating jaw with implant therapy ismigration of dental implants into maxillary sinus. Implant migration into the maxillary sinus may be followed by sign of infection and oroantral communication. This way, paranasal sinus function will be appearing altered after the implant migration and hence implant removal is utmost important.
