INTRODUCTION: Frequent and broad application of endoscopic sinus surgery (ESS) in parallel with experience makes it imperative to know the anatomy and the existing pathology very well before surgery. This study examines the association between anomalies in the sphenoid sinus area in paranasal sinuses computed tomography (PNS-CT) and pathological findings and determines variations of sphenoid sinus. METHODS: A total of 200 cases (100 women, 100 men) who had PNS-CT in the emergency and radiology polyclinics within the period of one year were included in this study...

OBJECTIVES: Saline irrigation of the nasal cavity and paranasal sinuses by one-way valved sinus containers has a recognised role in the management of chronic rhinosinusitis. However, bacterial recontamination of irrigation bottles through backflow from the sinonasal cavity is a concern in recurrent sinus cavity infections. While patients are encouraged to clean the irrigation bottles regularly, there remains significant concern that the use of contaminated bottles may perpetuate chronic rhinosinusitis...

Orbital surgeons are quite familiar with the diagnosis and management of paranasal sinus mucoceles due their frequent involvement of the orbit. These benign masses form and expand following sinus outflow obstruction secondary to various causes including trauma, inflammation and malignancy, amongst others. The authors present two cases of isolated orbital mucoceles without associated sinus outflow obstruction. There were notably no connections between the paranasal sinuses and the lesions. The mucoceles were diagnosed following orbitotomies and excisional biopsies with confirmatory histopathology...

Orbital inflammatory disease and secondary optic neuropathy is a rare but devastating complication of long-term intranasal cocaine abuse. We describe 2 patients with a history of intranasal cocaine consumption who presented with subacute onset of unilateral vision loss from optic neuropathy and limitation of abduction in the affected eye. Magnetic resonance imaging findings included an orbital mass in combination with absent nasal septum and partial destruction of the paranasal sinuses. Biopsies and histopathologic examination of the nasal cavity and the orbital mass revealed chronic inflammation...

OBJECTIVE: Balloon Sinuplasty for the management of paranasal sinus inflammatory diseases was introduced in otolaryngology in 2005. Over the past decade, evidence strongly supports its safety and efficacy for the treatment of chronic rhinosinusitis (CRS) in adults. Because it requires no bone or tissue removal, this procedure could be suitable in children. We present our initial experience of its use for the treatment of CRS in children. MATERIALS AND METHODS: A prospective study was performed of 30 children with failed medical therapy, who were scheduled for surgery...

About 50% of scuba divers have suffered from barotrauma of the ears and about one-third from barotrauma of paranasal sinuses. The sphenoid sinuses are rarely involved. Vital structures, as internal carotid artery and optic nerve, adjoin the sphenoid sinus. Thus, barotrauma could lead to serious neurologic disorders, including blindness. After searching the literature (Medline) and other sources (Internet), we present some cases of sphenoid sinus barotrauma, because these injuries may be underreported and misdiagnosed due to the lack of awareness and knowledge...

BACKGROUND AND OBJECTIVE: Interleukin (IL)-25 has been shown to play an important role in the pathogenesis of chronic rhinosinusitis with nasal polyps. Nasal polyps are associated with chronic inflammation of the mucous membranes in the paranasal sinuses and are involved in extracellular matrix (ECM) accumulation. The aim of this study is to evaluate the effects of IL-25 on myofibroblast differentiation, ECM production and the expression of matrix metalloproteinases in nasal polyp derived fibroblasts (NPDFs) and to determine the molecular mechanism underlying these processes...

PURPOSE OF REVIEW: Chronic rhinosinusitis (CRS) is a multidimensional inflammatory disorder of the nose and paranasal sinuses. We reviewed the recent literature to identify improved methods to assess, control, and manage these difficult to control patients. RECENT FINDINGS: The role of endotyping in CRS has offered a better understanding of the underlying pathophysiology and allows for more targeted treatment. The understanding of systemic disorders and their role in CRS and the importance of topical treatment reaching the sinuses has also allowed for better control of these patients...

INTRODUCTION: Osteomas of the paranasal sinuses are benign bone tumours that produce clinical signs depending on their size and location. In most reported cases large tumours are excised by an external approach or in conjunction with an endoscopic technique. Endoscopic treatment of such tumours is a huge challenge for the operator. OBJECTIVE: Determine the optimal surgical approach by analysing giant osteomas of the frontal and ethmoidal sinuses in the literature...

Orbital emphysema and associated pneumocephalus usually result from trauma to orbital bones or due to sinus disease, allowing air to travel from paranasal sinus into orbit and brain. However, it is extremely rare to have orbital emphysema and pneumocephalus in the absence of orbital wall fracture. In our case, a young male was admitted with severe eye pain, diminution of vision due to sudden exposure of compressed air gun. Examination revealed proptosed, emphysematous right eye with conjunctival laceration...

Introduction  Pneumosinus dilatans (PSD) is a rare phenomenon involving the expansion of the paranasal sinuses, without bony destruction or a mass. Previously documented cases have demonstrated simple expansion of a solitary air cell. We present two unique cases of PSD in the presence of meningioma, in which complex new cells developed within the frontal sinus. One of the two patients developed associated sinus disease. Case 1  A 28-year-old man presented with facial pain. A computed tomography scan showed an abnormally enlarged, septated right frontal sinus, not present on childhood scans...

Paranasal sinus mucoceles are mucus-containing cystic structures with an epithelial lining that completely fills in the paranasal sinuses. Although they are benign in nature, they may result in the destruction of the surrounding bony structures over time. Clinical findings such as exophthalmia, visual impairment, and diplopia occur due to pressure of the fronto-ethmoidal mucocele on the orbita. Currently, the endoscopic intranasal approach is preferred in the treatment of paranasal sinus mucoceles due to its minimal morbidity and low recurrence rates...
