Spontaneous intraorbital hematoma is an uncommon clinical entity seen in ophthalmology practice. It is poorly represented in the literature. Current evidence attributes it to orbital trauma, neoplasm, vascular malformations, acute sinusitis, and systemic abnormalities. A 65-year-old female presented with spontaneous intraorbital hematoma manifesting as severe ocular pains, eyelid edema, proptos...

Previously, anatomists considered paranasal sinuses as a mysterious region of the human skull. Historically, paranasal sinuses were first identified by ancient Egyptians and later, by Greek physicians. After a long period of no remarkable improvement in the understanding of anatomy during the Middle Ages, anatomists of the Renaissance period-Leonardo da Vinci and Vesalius-made their own contrib...

Osteomas are benign osteogenic neoplasms or hamartomas with a very slow growth rate. Osteoma is the most common mesenchymal neoplasm of the paranasal sinuses. In the jaws, the mandible is more commonly involved than the maxilla. Osteomas may occur at any age, but most frequently are found in individuals older than 40 years. Although most osteomas are small, some may become large enough to cause...

Background: Chronic rhinosinusitis (CRS) refers to a group of disorders characterized by inflammation of the mucosa of the paranasal sinuses. Computed tomography (CT) scans used as the gold standard diagnostic modality of nose and paranasal sinus diseases. There has been a lot of studies regarding the anatomic variations leading to pathogenesis of paranasal sinus diseases. Considerable progress...

Iatrogenic foreign bodies of the paranasal sinuses are extremely rare and, as a rule, during medical procedures. In this clinical case, fracture needle for puncture maxillary sinus required surgical treatment.

Background This study aimed to present the correlation between headaches and anatomical changes within nasal cavity paranasal sinuses. Material methods: includes a literature search our observations of 24 patients regarding with sinus anatomy.

A mucocele of paranasal sinuses is a collection of mucus within an epithelial lined sinus whose outflow tract is permanently obstructed. The most common site for a mucocele is the frontal sinus; it is less common in the other sinuses. Frontal mucoceles present in different ways depending upon their size and duration, with symptoms often gradual and insidious. Symptoms are mainly ophthalmic and ...

Idiopathic expansion of a paranasal sinus containing air and without an associated mass has been termed pneumosinus dilatans [1] . This rare disorder has been known to occur in all the paranasal sinuses, but it most commonly affects the frontal sinus. Clinical symptoms include pain , visual loss, proptosis, galactorrhea, and hypopituitarism [2-4]. Proposed mechanisms of origin include developme...

It is not fully understood why humans possess paranasal sinuses and for many years there has been speculation as to their physiological significance. Much the same uncertainty holds true for the pathophysiology of chronic paranasal sinusitis, a disease which represents a major therapeutic challenge despite recent medical and surgical progress. 3 There are probably several distinct subtypes of c...

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.
