Treating chronic rhinosinusitis (CRS) by nebulization requires an airflow capable to deliver medication to deep target sites beyond the nasal valve. Fixed frequency acoustic airflow technology is currently available, mainly as post-surgical therapy, but still have not been able to realize the full potential of direct nose to paranasal sinuses delivery. Reported herein are the application of frequency sweep acoustic airflow and the optimization of its frequency range, sweep cycle duration and intensity. The resonant frequencies of the model's maxillary sinuses can be estimated using the Helmholtz resonator theory...

Metastasis from distant primary tumors is extremely rare in the paranasal sinuses with few hundred cases in the literature. Metastatic carcinoma of the prostate is even rarer, despite being one of the most common tumors, with only 24 cases published. In this article, we report a case of a 58-year-old male presenting with epistaxis and nasal obstruction as initial symptoms of a metastatic prostate carcinoma in the ethmoid cells and maxillary sinus.

Introduction Thermography is a form of radiography that images the skin surface temperature. Thermograms are pictorial representations of thermal maps of the entire body's outer surface. Thermography was applied as an attempt to evaluate its usefulness in the diagnosis of chronic sinusitis (CS). Hence, this study was done to determine the diagnostic value of thermography for patients suffering from CS. Methodology Patients attending the Department of Otorhinolaryngology and Head and Neck Surgery over a two years' duration with symptoms suggestive of CS were included in this diagnostic evaluation study...

Allergic rhinitis (AR) is the most common form of allergy, which - as epidemiological research has shown - applies to nearly 25% of the population. AR significantly affects the quality of life of the patient, and the more severe the disease, the greater the risk of developing bronchial asthma. One of the factors affecting the severity of symptoms and the degree of their control is air pollution. In some patients, despite proper treatment, persistence or only partial remission of symptoms (uncontrolled allergic rhinitis) is observed...

Brain abscess (BA) is an encapsulated infection and can be the consequence of head and cranio-maxillo-facial surgery or trauma, or may be secondary to cavernous thrombophlebitis, but is most frequently due to hematogenous septic dissemination from an adjacent site of infection, such as the paranasal sinuses, middle ear or oral cavity. We report a rare and unfortunate case of multiple BA caused by dental procedures in a young man with undiagnosed patent foramen ovale (PFO). Simple routine dental procedures, such as tooth brushing and professional oral hygiene, can predispose to life-threatening conditions...

BACKGROUNDː Functional Endoscopic Sinus Surgery (FESS) is a minimally-invasive surgical technique for patients with paranasal sinus pathology. Surgical bleeding reduces operative field visibility and increases the incidence of serious complications. Epinephrine injection into the nasal mucosa and controlled hypotension are used to minimise bleeding. Hypotension carries risks and sometimes does not reduce surgical bleeding. The goal of this study is to discover which haemodynamic parameter better correlates with surgical bleeding...

Rhinosporidiosis is a chronic fungal inflammatory disease prevalent in India and Sri Lanka. Its manifestations are mostly nasal and extranasal lesions are relatively rare. Occasional atypical presentations of this disease lead to diagnostic dilemma. Herein we report on a case of nasopharyngeal rhinosporidiosis having extensive involvement of paranasal sinuses along with intracranial extension which mimicked radiologically as juvenile nasopharyngeal angiofibroma. To our knowledge, this is the first reported case of rhinosporidiosis having intracranial extension...
