PURPOSE To establish the incidence of thyroid carcinoma metastasis in adult patients presenting with apparently benign cervical cysts. The authors report their experience with four cases of papillary thyroid carcinoma who present with a lateral cervical cystic mass and no palpable disease in the thyroid gland. MATERIALS AND METHODS A retrospective review(More)
Sphenochoanal polyp is a rare entity which originates in the sphenoid sinus cavity and extends into the choana via the ostium. It presents in a similar manner to the more common antrochoanal polyp. Radiological examination is necessary to differentiate between these two types. We present a case of sphenochoanal polyp and review the clinical, radiological(More)
OBJECTIVES Computerized tomography (CT) is used widely to diagnose deep neck infections (DNIs), and, generally, the decision of surgical intervention is based on findings of a CT study. This study examines the accuracy of CT in differentiating abscess versus cellulitis in DNIs (lateral pharyngeal and retropharyngeal). STUDY DESIGN This is a retrospective(More)
The purpose of this prospective study was to evaluate microsurgical thyroidectomy by comparing it with traditional thyroidectomy. Before surgery, patients were assigned either to the microscopic thyroidectomy group (MT group), with the use of the surgical microscope, or the traditional thyroidectomy group (TT group), without the use of visual magnification.(More)
PURPOSE Nitric oxide (NO) in the exhaled air is mainly produced by the upper respiratory airway mucosa, and the output of NO has been found to differ from normal in sinonasal disease. In allergic rhinitis (AR) nasal NO output (V(NO)) has been reported to increase compared with healthy individuals. The purpose of this study was to observe daily variations in(More)
Nitric oxide (NO) in exhaled breath is produced primarily by the upper respiratory airway mucosa. The nasal output of this gas is increased in patients with allergic rhinitis. We performed a study on a 41-year-old nonsmoking male volunteer with allergic rhinitis to investigate the effect of fluticasone nasal spray on nasal NO output (VNO). A total of 28(More)
Laryngotracheal foreign bodies, although less common than bronchial foreign bodies, are potentially more dangerous. We report a 10-year-old girl with Down syndrome with asthma bronchiale symptoms, which was later found to be the result of a thin bone lamella impacted in her larynx. There was no clear history of foreign body aspiration. She was treated with(More)
Nitric oxide (NO) is produced from L-arginine in mammalian tissues. Nitric oxide synthase (NOS) catalyzes this reaction in human tissues. It has been shown that NO serves as an important signaling molecule in the cardiovascular system and is responsible for vasoregulation. In 1991, NO was discovered in exhaled air. More recently, it has been shown that the(More)
Prior to 2003, only 39 cases of oncocytic carcinoma of salivary gland origin had been reported in the English-language literature. We report a new case, which occurred in a 48-year-old woman whose disease had metastasized to regional lymph nodes. She was treated by radical parotidectomy, with sacrifice of the facial nerve, and radical neck dissection. At(More)
Despite advances in technology, the radiologic assessment of certain head and neck lesions may still pose difficulties because of the complex anatomy of this region, the small and mobile structures that this region harbors, and the apposition of mucosal surfaces in the neutral position. Certain maneuvers have been described in the literature to overcome(More)
