OBJECTIVES We evaluated the outcome of adenotonsillectomy for obstructive sleep apnea syndrome (OSAS) in children using polysomnography (PSG) data and a quality-of-life (QOL) instrument. METHODS We enrolled children (4 to 14 years of age) who had OSAS diagnosed by overnight PSG and who underwent both adenoidectomy and tonsillectomy between January 2003(More)
OBJECTIVE To investigate the expression of E-cadherin and its relationship with clinicopathological parameters in laryngeal squamous cell carcinoma (LSCC). METHODS Sixty-four patients who had previously undergone complete resection of tumor for LSCC were studied retrospectively. The level of E-cadherin expression in tumor tissues and paired nontumor(More)
BACKGROUND Traumatic optic neuropathy (TON) is an important cause of severe loss of vision due to blunt or penetrating head trauma. The pathogenesis of TON remains unclear, and there are several potential causes for the observed loss in vision. Endoscopic optic nerve decompression (EOND) has been reported to improve the visual prognosis in TON cases, but(More)
PURPOSE To investigate the expression and quantity of glucocorticoid receptor-alpha and -beta in polyp tissues taken from the patients treated were subsequently treated with topical glucocorticoid (GC). METHODS Eighty patients with nasal polyps were initially enrolled in the study. All polyp specimens were obtained prior to treatment. Patients then(More)
OBJECTIVE To explore the expression of γδ T cells in chronic rhinosinusitis (CRS) and its potential significance in pathogenesis. METHODS γδ T cell expression was detected by immunohistochemistry (Envision method). From polyps (25 CRS patients with nasal polyps, CRSwNP), inferior turbinate mucosa (13 CRS patients without nasal polyps, CRSsNP), and 16(More)
OBJECTIVE To explore the method of reducing bleeding during endoscopic sinus surgery for chronic sinusitis and nasal polyp. METHODS Bleeding during surgery and the effective rate of two groups patients with chronic sinusitis and nasal polyp were compared (68 cases in group A with preoperative treatment, 30 cases in group B without preoperative treatment).(More)
PURPOSE To summarize the experience and explore the clinical application of myringoplasty with autogenous adipose tissue by endotoscope. METHODS In this study, we retrospectively analyzed 56 cases (64 ears) of otoendoscopic myringoplasty with autogenous adipose tissue performed between January 2006 and April 2007. RESULT All patients were followed up(More)
OBJECTIVE To evaluate the value of Advantage Windows 3.1 (AW 3.1) software for anatomical study of nasofrontal region, and to study the CT characteristics of nasofrontal region which related to the frontal sinus surgery. METHODS Eighty patients underwent axial consecutive computed tomography scans and these data were studied with AW 3.1 software which(More)
BACKGROUND Recent studies suggest that epithelial cell (EC)-derived cytokines contribute to allergic airway disease exacerbation. OBJECTIVE To confirm our hypothesis that atopic dendritic cells (DCs) are activated to up-regulate the receptors of cytokines that mainly derived from ECs and enhance TH2 responses. METHODS The expressions of interleukin 17(More)
