The antrochonanal polyp (ACP) is defined as a maxillary sinus polyp that originates in the maxillary sinus, passes through the sinus ostia, and extends into the choana. The aim of this study was to compare the histologic findings of 40 cases of ACP with those of allergic and non-allergic nasal polyps, and so possibly to elucidate the pathogenesis of ACP. No(More)
Acoustic rhinometry and rhinomanometry have been used to assess nasal airway patency objectively. We compared nasal obstruction symptoms before and after decongestion with several parameters of these objective tests. The patients assessed their nasal obstruction using a visual analogue scale (VAS). Cross-sectional areas and nasal resistance were measured by(More)
Congenital aural atresia is a relatively common anomaly in otology. It requires an early assessment of hearing status and an early evaluation of the degree of atresia. Its surgical management is aimed at obtaining hearing gain and at establishing appropriate auditory canal status for the application of hearing aids. The authors analyzed the preoperative(More)
We attempted to evaluate postoperative mucosal changes and symptomatic improvement in 99 patients who underwent functional endoscopic sinus surgery from September 1991 through August 1992. The patients were divided into 2-, 4-, 6-, and 12-month postoperative groups. Thickness of the maxillary sinus mucosa measured at the midpoint of the lateral sinus wall(More)
The authors aimed to evaluate the validity and characteristics of acoustic rhinometic tests by comparing the results with those of computed tomography (CT) of the nasal cavity. Cross-sectional areas along the nasal cavity were measured by acoustic rhinometry (AR) and CT of the nasal cavity in 30 normal subjects. Cross-sectional areas measured by each(More)
Nasal polyps are the most common mass lesion of the nasal cavity. Various pathogenetic mechanisms have been proposed. However, the cause is still largely unknown, and treatment methods have not been changed for several hundred years. In order to investigate the role of cytokines in the pathogenesis of nasal polyps, expression of cytokine messenger RNAs(More)
OBJECTIVES Temperature-controlled and temperature-monitored radiofrequency tissue volume reduction (RFTVR) for the turbinate is a new treatment modality for nasal obstruction secondary to turbinate hypertrophy. We compared the nasal functions after the treatment ofRFTVR and laser vaporizing turbinoplasty (LVT) using subjective symptom scores and objective(More)
To investigate the expression of cytokine mRNAs in nasal polyps and the role of allergy in the pathogenesis of nasal polyposis, we studied the expression of IL-4, IL-5, and IFN-gamma mRNAs using the RT-PCR and Southern blot. Nasal polyp specimens were obtained from 14 patients with infectious rhinitis and 5 patients with perennial allergic rhinitis.(More)
This study aimed to investigate expression of various cytokine mRNAs, including IL-6, IL-8, TGF-beta, IL-4, IL-5, and IFN-gamma in maxillary sinus mucosa of patients with chronic sinusitis. Maxillary sinus mucosae of six patients with chronic sinusitis and turbinate mucosae of six healthy subjects were obtained. We performed RT-PCR and Southern blot to(More)
BACKGROUND Though mucosal cysts in the paranasal sinuses (PSMCs) are common findings on radiographic images, the nature of PSMCs and risk factors for the development of PSMCs have not yet been determined. The aim of this study was to evaluate the characteristics of PSMCs using brain magnetic resonance (MR) imaging. METHODOLOGY/PRINCIPAL A total of 6831(More)
