The shape of the temporal bone of the adult human cranium, specifically the mastoid region, is documented widely in past literature as a measure of sexual dimorphism within and among human populations. Yet, past research focus primarily on the qualitative assessment of the size of the mastoid region as it varies between males and females. This study explores both standard qualitative and standa...

BACKGROUND To identify predictors for development of mastoiditis after intensity-modulated radiation therapy (IMRT) in nasopharyngeal carcinoma (NPC). METHODS Data for 146 NPC patients treated with IMRT was retrospectively reviewed under institutional ethics committee approval. Clinical factors associated with mastoiditis were analyzed. Dose-volume histogram analysis was performed for the Eus...

We present a case of gastric varices successfully treated with modified plug-assisted retrograde transvenous obliteration. A 45-year-old male patient had isolated fundal caused by alcoholic cirrhosis. Contrast-enhanced computed tomography showed that the were drained mainly via gastro-renal shunt. The obliteration using an IMPEDE vascular plug coil-assisted obliteration-II procedure. There no c...

AIM To review the literature on pulp chamber and root canal obliteration in anterior teeth and to establish a clear protocol for managing teeth with fine, tortuous canal systems. SUMMARY Pulp canal obliteration (PCO) occurs commonly following traumatic injuries to teeth. Approximately 4-24% of traumatized teeth develop varying degrees of pulpal obliteration that is characterized by the appare...

UNLABELLED Computed tomography-based measurements of mastoid surface area and volume have not been described for adult Brazilian individuals. These measurements add to the understanding of middle ear physiology, related diseases, and their impact on mastoid pneumatization. OBJECTIVE To check the ratio between mastoid surface area and volume. METHOD This contemporary cross-sectional cohort s...

SummaryMalignant tumours of the mastoid are rare, the majority being squamous cell carcinomas. We report two cases whose clinical presentation mimicked mastoid abscess with intracranial complications. The first case is a twenty year Nigerian lady who presented to the Emergency Room of the Otorhinolaryngology Department with a one month history of headache, low grade fever, left facial palsy, ne...

OBJECTIVES Patients who fail endoscopic drainage procedures for chronic frontal sinusitis often require obliteration of the frontal sinus with abdominal fat. The purpose of this study was to evaluate an endoscopic technique for frontal sinus obliteration. STUDY DESIGN AND SETTING Retrospective case-control. Thirty-five patients underwent frontal sinus obliteration using either an endoscopic (...

OBJECTIVE Congenital mastoid cholesteatomas are rare lesions of the temporal bone. The clinical presentation of these lesions is variable, making them difficult to identify preoperatively. We evaluated our series of mastoid congenital cholesteatomas (CCs) in an effort to better define the clinical presentation, imaging characteristics, and surgical challenges specific to this lesion. STUDY DE...

The incidental finding of an enlarged mastoid foramen on the right posterior mastoid region of temporal bone is reported, together with a discussion of its clinical significance. A 67-year-old female underwent the pre-implant assessment of a maxillary left edentulous region. A cone-beam computed tomographic (CBCT) image was acquired and referred for consultation. Axial CBCT slices revealed a un...
