Intracranial metastasis of prostate cancer is rarely seen, and there are few studies in this regard in the literature. Most of these studies in the literature comprise the metastasis of prostate cancer to the sphenoid sinus, and metastasis to the frontal and ethmoid sinus is a much rare entity. Association of visual symptoms, epistaxis, headache, and hematuria may indicate a urologic malignancy in terms of the origin of the primary tumor. This study was aimed to present the prostate cancer case of a 73-year-old patient whose paranasal sinus tomograms revealed the presence of frontal and ethmoid sinus metastasis...

The aim of this study is to describe the morphology of frontal recess area with its anatomical variations and to reveal if frontal recess morphology and the anatomical variations related to that region have effects on the pneumatization of the frontal sinuses. The frontal sinus and recess morphometry of 136 sides of 68 dry skulls were evaluated on multislice high-resolution computed tomography. The relationships between frontal sinus and frontal recess measurements were analyzed by correlation and linear regression analysis...

OBJECTIVE: Eosinophilic chronic rhinosinusitis (ECRS), a subgroup of chronic rhinosinusitis with nasal polyps, is a refractory disease closely associated with bronchial asthma. We recently reported on the efficacy of ultra-fine particle inhaled corticosteroids (ICS) (hydrofluoroalkane-134a-beclomethasone dipropionate: HFA-BDP) exhalation through the nose (ETN) treatment for mild-to-moderate asthmatics with ECRS. However, the effect of HFA-BDP ETN was found to be transient in some cases with severe ECRS and asthma, requiring treatment with higher-dose ICS and long-acting β2-agonists (LABA)...

The osteomeatal complex plays an important role in the development of Chronic rhinosinusitis. The ethmoidal infundibulum is bordered medially by the uncinate process, and the anatomic relationship between the ethmoidal infundibulum and the frontal recess may depend upon the types of attachment of the uncinate process. The osteomeatal complex is the main area targeted in chronic rhinosinusitis and within it uncinate process is the first anatomical structure encountered. The aim of this study was to evaluate the types of attachment of the uncinate process and its implications in the development of sinus inflammation...

BACKGROUND: Functional endoscopic sinus surgery is recognised to have a significant complication profile (e.g. blindness, cerebrospinal fluid leak and intracranial sepsis). Pre-operative computed tomography imaging is considered mandatory for surgical planning to reduce intra-operative risk. A radiological report is the 'gold standard' in image interpretation; however, because of a lack of otolaryngological or radiological guidance, its contents may be variable. By surveying practising otolaryngologists, this study aimed to provide some guidance which may be used by radiologists to produce more surgically relevant radiological reports...

A 73-year-old male patient underwent a right nephrectomy for renal cell carcinoma in 2008, and interferon-alpha was initiated as adjuvant treatment. Computed tomography (CT) scans showed lymphadenopathy above the left diaphragm, and treatment with interferon-2 was subsequently initiated in 2009. Nasal bleeding manifested in February 2010, and CT scans showed a soft-tissue density mass mainly located in the ethmoid sinus. A biopsy of the lesion was performed, and metastatic renal cell carcinoma was diagnosed...

Propel and Propel Mini sinus implants are mometasone furoate-coated bioabsorbable stents used as an adjunct in the management of chronic rhinosinusitis after endoscopic sinus surgery. The original sinus implant was deployed in the ethmoid sinuses to provide medialization of the middle turbinate, decrease scarring and mucosal adhesions, limit polyp regrowth, and reduce mucosal inflammation. A structurally smaller version of the Propel, the Propel Mini, was developed and now has been approved for endoscopic placement in the frontal sinuses...

The widespread use of dental implants and reconstructive procedures for their positioning has led to an increase in sinonasal complications of dental disease and treatment (SCDDT). Diagnosis requires accurate dental and rhinological evaluation, including computed tomography (CT). The aim of this study is to investigate a multidisciplinary approach for the treatment of SCDDT by combining endoscopic endonasal surgery (EES) and an intraoral approach on the basis of a preliminary classification system already proposed by other authors...

Although functional endoscopic sinus surgery is an effective means of treating patients with recurrent and refractory sinusitis, the procedure is not without risk of serious surgical complications. Preoperative computed tomography (CT) affords radiologists the opportunity to prospectively identify anatomic variants that predispose patients to major surgical complications; however, these critical variants are not consistently evaluated or documented on preoperative imaging reports. The purpose of this review is to illustrate important anatomic variants and landmarks on the preoperative sinus CT with a focus on those that predispose patients to surgical complications...

Sinonasal neuroendocrine tumours (NETs) are rare, aggressive neoplasms with a high recurrence potential. There are no robust protocols for the management of these tumours. An 81-year-old man presented with an incidental sinonasal mass visualised on CT scan of head. Over the next few weeks he developed new onset, progressively worsening headache, right eye ptosis and restricted extraocular movements. Imaging confirmed a rapidly enlarging tumour involving the right nasal cavity and the orbit. Biopsy showed a large cell neuroendocrine carcinoma of the right ethmoidal sinus...

BACKGROUND: Olfactory neuroblastoma (ONB) is an uncommon neoplasm that arises from olfactory epithelium in the nasal cavity near the cribriform plate. Although local recurrence or direct extension along olfactory epithelium and metastasis to the central nervous system has been reported, remote leptomeningeal metastasis is quite rare. In our report of a leptomeningeal metastasis of ONB without recurrence of primary site, we discuss the possible pathogenesis of this rare phenomenon with a review of the literature...

CONCLUSION: By means of three-dimensional display of the critical measurements, the authors suggest a novel definition of 'dangerous ethmoid'. Parallel to Keros type III, the proposed determining factors include: olfactory fossa width >6 mm, its distance to the medial nasal concha (turbinate) <20 mm and to the orbit interval of <10 mm. Clinical evaluation of these preliminary criteria based only on radiological data is required and underway. OBJECTIVES: Detailed pre-operative assessment of sinus computer tomography (CT) scans reduces the frequency of severe complications in patients undergoing endoscopic sinus surgery (ESS)...

Osteomas are the most common benign tumors of the paranasal sinuses. They are usually localized in the frontal sinus. Giant osteomas of the frontal sinuses are very rare but readily extend into the intraorbital or intracranial cavity, causing serious complications. This is a report of a 14 year-old boy with a bulging in frontal area and asymptomatic giant osteoma of the frontal sinuses. He had a history of minor trauma that had a bulging after 3 months. However, he referred to a plastic surgeon after 15 months...

Rhabdomyosarcoma (RMS) is a fast growing, malignant tumour arising from immature mesenchymal cells, committed to skeletal muscle differentiation. It is more often seen in the paediatric population and constitutes less than 1% of all malignancies and less than 3% of all soft tissue tumours. RMS of the paranasal sinuses constitutes 10-15% of adult head and neck RMS, ethmoidal and maxillary sinuses being the most common. We report a 56-year-oldman presenting with left nasal obstruction, epistaxis on and off and left cheek swelling...

Introduction. A range of traumatic, vascular, inflammatory, infectious, and neoplastic processes can affect the orbit and its structures. In the area of otolaryngology, the rhino-orbital-cerebral involvement of invasive fungal rhinosinusitis can affect the orbit, which may look like initially a rhinosinusitis or even mimic malignancy. Case Presentation. Female patient, 32 years old, with headache and ocular proptosis. She was using prednisone in immunosuppressive doses for a year and had breast cancer treated three years earlier...
