mucoceles are defi ned as chronic, cystic lesions in the paranasal sinuses. when the mucocele content becomes infected, the lesion is defi ned as mucopyocele. most mucoceles are located in the frontal and anterior ethmoid sinuses and normally they involve the frontal-ethmoid complex, expanding to the superior-medial region of the orbit, leading to ocular disorders; maxillary sinus presentation ...

Alveolar rhabdomyosarcoma (RMS) has a predilection for the deep soft tissues of the extremities and mainly occurs in children. Although the tumor may originate in other sites, such as the nasal cavity or paranasal sinus, invasion of the orbit is unusual. We describe the clinicopathological features of 2 cases of alveolar RMS of the nasal cavity or paranasal sinus in adult patients with orbital ...

Orbit is an innocent bystander that is afflicted by lesions of the Paranasal Sinuses (PNS). Orbits share 3 walls with the sinuses, frontal sinuses on the supero-medial aspects of the orbits, ethmoid sinuses medially and maxillary sinuses inferiorly. Between the ethmoids and the orbits, there is lamina papyraecea which is a very thin bone. Between the maxillary sinus and the floor of the orbit, ...

The orbit is involved in 10% of all lymphomas. Paranasal sinuses and nose are other sites for extranodal lymphoma that are involved in upto 2.6 to 6.7% of lymphomas involving head and neck region and are second most common presentation of extranodal lymphoma. In nearly 22.5% of patients, sinonasal lymphoma and orbital lymphoma may coexist. The present report describes such patient with first pr...

Inverted papilloma is an interesting benign tumour arising from lining epithelium of paranasal sinuses which most commonly involves nasal cavity and sinuses. Extension to orbit a rare presentation. It uncommon intermediate grade epithelial the cavity, with tendency recur associated malignancy, Schneiderian membrane Reporting case inverted right well differentiated squamous cell carcinoma, invad...

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...

Orbital chondrosarcomas are extremely rare and are usually an extension of tumours involving the paranasal sinuses. A unique case of dedifferentiated chondrosarcoma arising solely within the orbit is presented.

Osteomas are the most common benign tumors of the paranasal sinuses. They are usually localized in the frontal sinus and less often in the other paranasal sinuses. In this article, we report the surgical treatment of an unknown frontal sinus osteoma discovered after an acute exophthalmos. We have chosen an external approach to obtain a radical excision of the tumor, but we prefer a direct front...

Rhinocerebral mycosis is an invasive fungal infection which occurs primarily in the paranasal sinuses and progresses to involve the brain and/or the orbit. It is commonly seen in immunocompromised individuals and can be most effectively treated if diagnosed early, when it is limited to the nasal cavity and the paranasal sinuses. Even though it is acceptable that surgical debridement in combinat...
