Introduction: Nasal polyps are pedunculated, edematous, prolapsed mucosa of the paranasal sinuses. These polyps commonly arise around the ostia of the paranasal sinuses in the middle meatus. Discussion: The commonest sites of polyp formation are the ethmoid sinuses and maxillary sinus. Rarely polyps may also arise from the other paranasal sinuses. Sites in the nasal mucosa other than the parana...

CONTEXT Paranasal sinus cancer is considered rare, with an incidence of less than 1 per 100,000 per year, with the frontal sinus being the primary site in only 0.3%. We report a case of adenocarcinoma arising in the frontal sinus. DESIGN Case report. CASE REPORT A 59-year-old woman, secretary, came in February 1998 with a 4-month history of low intensity frontal headache. She denied contact...

Juvenile Paget's disease (JPD) is a rare skeletal disorder that's characterized by bone demineralization and elevated levels of serum alkaline phosphatase. JPD involves the paranasal sinuses in extremely rare cases. We report here on a 25-month-old Asian male who was diagnosed of JPD associated with aplasia of the paranasal sinuses, but not the ethmoid sinuses. The patient was successfully trea...

The maxillary sinus is an airfilled cavity and is part of a series of paranasal sinuses and impacts most on the work of oral and maxillofacial surgeons as they will often be required to make a diagnosis in relation to inflammation, orofacial pain, tumour, etc. It could be mainly sinogenic or odontogenic in origin. Maxillary sinus diseases are often coincidentally observed on radiographs, and ph...

Despite the advances in modern antimicrobial treatment, paranasal sinus disease remains relatively common. A case of chronic inflammatory frontal sinus disease presented with unilateral recurrent eyelid swelling. Clinical features and management in conjunction with ENT are discussed. An extensive literature search has shown only one other similar case reported in Russian language whose manageme...

We report an unusual case of primary intracranial germinoma involving the sphenoid bone and sinus. To the best of our knowledge, paranasal sinus and bone invasion of primary intracranial germinoma has not been previously reported. Recognition of this rare form of presentation by imaging is important because early radiation and chemotherapy can result in a cure of this neoplasm.

OBJECTIVES We present the clinical and radiological features, treatment protocols, and medium-long-term results of our patients following surgery for paranasal sinus mucocele, along with a review of the relevant literature. MATERIALS AND METHODS A total of 18 patients (11 women and 7 men) who underwent surgery for paranasal sinus mucocele at Kocaeli University Faculty of Medicine, Department ...

OBJECTIVE Paranasal sinus balloon catheter dilation (BCD) represents a commonly used tool in the management of chronic rhinosinusitis (CRS) for which the indications, utilization, and outcomes have not been well established. A systematic review and meta-analysis were undertaken to evaluate change in quality of life and sinus opacification following paranasal sinus BCD in the treatment of CRS. ...

Patients with a paranasal disorder often manifest voice change. Yet, computer simulation of these nasal sounds is difficult using a nasal tract model without any branching cavity. In other words, acoustic property of the nasal tract is influenced by a coupling with the paranasal sinuses. If the transfer function of the sinus acts as a Helmholtz resonator, the resonance frequency, or "zero" poin...
