OBJECTIVE To determine the predictors affecting treatment outcome after application of the mandibular advancement device (MAD). DESIGN Retrospective analysis. SETTING Tertiary care university hospital. PATIENTS A total of 76 patients (68 men and 8 women) who were treated with the MAD for obstructive sleep apnea (OSA) were included from September 2005(More)
OBJECTIVE To evaluate retrospectively the efficacy of the mandibular advancement device (MAD) in patients with obstructive sleep apnea in terms of positional dependency. DESIGN Retrospective analysis. SETTING Academic tertiary referral center. PATIENTS One hundred patients with obstructive sleep apnea treated with the MAD at the Department of(More)
PURPOSE To investigate prognostic values of nasopharyngeal carcinoma (NPC) with skull base invasion for optimal management, according to its extent of involvement. METHODS From January 1985 through December 2000, 119 patients with histologically proven NPC were analyzed retrospectively with review of their computed tomography/magnetic resonance imaging(More)
BACKGROUND The optimal chemotherapy regimen for the treatment of olfactory neuroblastoma has not been clearly defined. The purpose of the current study was to evaluate the efficacy of neoadjuvant chemotherapy with the combination of etoposide, ifosfamide, and cisplatin (VIP) for patients with olfactory neuroblastoma. METHODS Eleven consecutive patients(More)
BACKGROUND Nasal packing is commonly performed after functional endoscopic sinus surgery (FESS). However, nasal packing is associated with higher cost (owing to the cost of packing materials), patient discomfort, delayed wound healing, and concern about toxic shock syndrome. Some surgeons have been performing FESS without packing, but there are few studies(More)
After functional endoscopic sinus surgery (FESS), nasal packing may be necessary and a packing material which has benefits in both cost and efficacy would be required. This study aimed to determine the efficacy of Gelfoam packing on hemostasis and wound healing after FESS. Patients who underwent bilateral FESS due to chronic bilateral rhinosinusitis were(More)
The apnea–hypopnea index (AHI) is closely related with the severity of daytime sleepiness, but excessive daytime sleepiness (EDS) is not presented on all patients with obstructive sleep apnea (OSA). It is unclear why daytime sleepiness is not always present in OSA patients even if their sleep is disrupted from the perspective of polysomnographic findings.(More)
The purposes of this study were to evaluate clinical outcome of mandibular advancement device (MAD) for obstructive sleep apnea (OSA) patients and to estimate influencing factors on MAD effect. From the patients who were diagnosed as OSA by polysomnography at Seoul National University Bundang Hospital from January 2007 to February 2009, the patients who(More)
