The objective of the study was to estimate the normal upper and lower limit cut-off value of the different dimensions of maxillary and frontal sinuses, and also to determine the influence of gender on the obtained variables and to observe the effect of nasal septal deviation on maxillary sinus. The observational study was carried out and a total of 60 samples were collected from both males and ...

OBJECTIVE The purpose of this study was to determine the prevalence, height, location and morphology of maxillary sinus septa in dentate, partially dentate and edentulous adults as well as in mixed dentition children using cone beam computed tomography (CBCT) for maxillary sinus surgical interventions. SUBJECTS AND METHODS Five hundred and fifty-four sides in the CBCT scans of 272 patients (3...

Silent Sinus Syndrome (SSS) is known to be a rare clinical condition, characterized by spontaneous and progressive enophthalmos and hypoglobus associated with atelectasis of the maxillary sinus and alteration of the orbital floor. Most of the patients with this syndrome present with ophthalmological complaints without any nasal sinus symptoms, and it typically has a painless course and slow dev...

OBJECTIVE To investigate the anatomical characteristics of the nasal cavity and paranasal sinuses in relation to the presence of sinusitis in patients with cleft lip and palate. DESIGN Retrospective survey. SETTING Tertiary care hospital. PATIENTS Forty-seven consecutive patients with cleft lip and alveolus with or without cleft palate. MAIN OUTCOME MEASURES The patients underwent compu...

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...
