Introduction: The close relationship between diseases of the paranasal sinuses system and the orbit is based on their anatomical relationship. About 60% to 80% of the osseous eye socket is made up by sinus walls. Objective: To describe evaluation of orbital complications in patient with paranasal sinuses diseases at Dr. M. Djamil Hospital Padang for 2005-2014. Method: Descriptive study we obtai...

We used pipe models to investigate the effects of paranasal sinus ostium size and paranasal sinus volume on the area-distance curves derived by acoustic rhinometry (AR). Each model had a Helmholtz resonator or a short neck as a side branch that simulated the paranasal sinus and sinus ostium. The AR-derived cross-sectional areas posterior to the ostium were significantly overestimated. Sinus vol...

non-penetrating head injuries associated with skull base fractures can lead to the development of pneumocephalus upon airs ingress, which leads its course in the subarachnoid space. intracerebral air accumulation is rare and ensuses when a paranasal sinus fracture is associated with a ensues when a paranasal sinus fracture is associated with a nearby parenchymal contusion. a 25-year old man is ...

Introduction/Background The paranasal sinuses consist of the maxillary, ethmoid, sphenoid, and frontal sinuses. They communicate with the nasal cavity in the midline and all structures together form a group of air-filled cavities where cancers can arise, grow, and spread without encountering significant barriers to local extension. Cancers of the paranasal sinuses and nasal cavity are rare mali...

BACKGROUND Olfactory neuroblastoma is a rare paranasal sinus malignancy. The traditional approach was craniofacial resection (CFR) and then postoperative radiotherapy until 1998. This review will chart development of a new protocol. METHODS This ethics-approved audit evaluated the number of new patients diagnosed with olfactory neuroblastoma, with information relating to patient, disease, and...

The current work aimed to analyse the anatomical findings of the nasal and paranasal sinuses of the donkey by gross anatomical observation of the skull and cadaver head, cross-sections, sagittal sections and computed tomography (CT) imaging. Seven adult donkeys and ten skulls were used in this study. The donkey head had six pairs of sinuses, three paranasal; the frontal, maxillary, and sphenopa...

The paranasal sinus system of horses is complex, comprising six pairs of sinuses. Disease processes that can develop in the sinuses include ethmoid hematomas, cysts, neoplasia, and bacterial and fungal infections. Horses that develop paranasal sinus disease vary widely in age. A significant number of clinical conditions involving the paranasal sinuses require a combination of diagnostic tests t...

BACKGROUND We hypothesized that higher body mass index (BMI) was associated with increased prevalence of paranasal sinus disease and examined the hypothesis in Japanese adults. METHODS This was a cross-sectional study including 1350 Japanese adults aged 40 years or more who participated in a health check-up program focusing on brain diseases and metabolic syndrome. Participants were divided i...

Fibro-osseous lesions of the face and paranasal sinuses are relatively uncommon. These lesions have overlapping clinical, radiologic and pathologic features causing difficulty in diagnosis. Neoplastic fibro-osseous paranasal sinus lesions can be benign or malignant. The benign fibro-osseous lesions described are: ossifying fibroma (and its histologic variants) and fibrous dysplasia. The variant...

Bilateral paranasal sinus mucoceles are rare. To date, only 5 cases have been reported in the English-language literature. All were bilaterally symmetrical. We present a patient with bilateral asymmetric mucoceles. This patient had a symptomatic mucocele of the right ethmoid sinus with orbital extension and an asymptomatic mucocele involving the left maxillary sinus with retroorbital extension....
