Background and Objectives:The aim of this study was to observe the effects of midle meatal antrostomy (MMA) on ciliary beat frequency (CBF) and histopathology of the nasal mucosa in experimentally induced maxillary sinusitis in rabits. Materials and Method:Maxillary sinusitis was induced in both maxillary sinuses (MSs) of 30 Pasturellapartially occluding the natural ostium and inoculating with P. aeruginosa. After 4 weeks, the MS and inferior turbinate mucosae were obtained in 5 rabits. In the remaining 25 rabbits, the ostia were reopened. Five rabbits were sacrificed 2, 4, 6, 8, and 12 we-eks after MMA, respectively and the MS and inferior turbinate mucosae were obtained. Another 5 normal rabbits were used as a control group. CBF was measured by video-computerized analysis. Degree of inflammation in histopathology was graded using ups. Results:CBF of the MS mucosa significantly improved after MA in a time-dependent patern, but did not reach a normal level even after 12 weeks. CBF of the inferior turbinate mucosa significantly improved after MMA in a time-dependent pattern, and reached a normal level after 12 weeks. Inflammation scores of the MS and inferior turbinate mucosae were significantly decreased after MMA in a time-dependent pattern. However, they did not reach a normal level of the control group even after 12 weks. Conclusion:MMA can improve not only the primary inflammation of the MS mucosa but also functionally and morphologica-lly improve the secondarily developed inflamation of the nasal mucosa in experimentaly induced maxillary sinusitis in rabbits.

We developed the remote bridge monitoring system for safety surveillance based on web. BMSWare(Bridge Management System Middleware) was implemented as a middle ware to process the sensor data in real time. The developed system operates on web, so the system can be used as a general safety surveillance system for bridges. In various environments according to geographical locations, it can obtain reliable data from various loggers and sensors without re-programming. The main functions of the system include the data acquisition, processing, backup and wireless transmission of the collected data. It was proved reliability and effectiveness of the monitoring system by application of real bridge(Mooyeong bridge).

Background and Objectives:Conventional turbinoplasty and laser-assisted partial turbinoplasty (LAPT) are commonly performed to control nasal obstruction secondary to inferior turbinate hypertrophy. Coblation, one of radiofrequency electro-compare the postoperative outcome of Coblation-asisted partial turbinoplasty (CAPT) with that of LAPT. Materials and Method:Forty-one patients with nasal obstruction due to inferior turbinate hypertrophy refractory to medical therapy were prospectively evaluated with a folow-up period of 6 months. Twenty-one patients (42 sides) were treated with LAPT, and 20 patients (39 sides) with CAPT. Postoperative changes in degre of nasal obstruction, minimal cross-sectional area (MCA) (V5), operation time, duration of crust formation, operation-associated pain, intraoperative bleeding and episodes of delayed bleeding were compared betwen the two surgical methods. Results:Crust was formed for a shorter postoperative period and operation-associated pain was less in the LAPT group. Nasal patency (MCA and V5) was more improved and operation time was shorter in the CAPT group. However, there were no significant diferences in improvement of nasal obstruction and operation-associated bleeding between the two groups. Conclusion:Thorough knowledge of advantages and limitations of LAPT and CAPT is required for clinicians to make appropriate use of surgical tols for the given patient characteristics and medical environment.

Sinochoanal polyp is an inflammatory polyp that originates in the paranasal sinus, pases through a sinus ostium, and extends into the choana. While antrochoanal polyp is the most comon type of sinochoanal polyp, sphenochoanal polyp is rare and ethmochoanal polyp is extremely more rare to find. To minimize postsurgical recurrence, it is essential to completely remove the polyp together with the base of its origin. We have recently experienced and successfuly managed three cases of ethmoc-polyps asociated with chronic rhinosinusitis. For this reason, ethmochoanal polyp should be suspected and completely removed together with the base of its origin when a large polyp originates from the ethmoid sinus and extends into the choana. Now we report three cases of ethmochoanal polyp with a brief review of the related literatures. (Korean J Otolaryngol 2002;45:921-5)
이개 연골과 측두근막의 자유 복합 이식을 이용한 비중격천공의 비내 재건술

Background and Objectives:The aims of this study are to introduce an intranasal repair technique of nasal septal perforation using a fre composite graft of the auricular cartilage and the temporalis muscle fascia and to determine its eficacy by evalua-ting the treatment outcome. Materials and Method:Nine symptomatic patients (7 males and 2 females, aged 23 to 66 years) with nasal septal perforation were included in this study. They were all refractory to conservative treatments and they underwent and perforations were retrospectively evaluated with a mean follow-up period of 21.7 months. Results:Preoperative symptoms included nasal obstruction, crust formation, rhinorrhea, epistaxis and foul odor. Septal perforation was asumed to have resulted in three patients from septal surgery, trauma and idiopathic causes, respectively. In all patients, the perforation size was 20 mm or les (mean:12.2× 8.4 mm) in diameter and located at the cartilagenous portion, not near the nasal dorsum. The perforations patients showing incomplete closure, respectively. However, clinical symptoms disapeared in 8 of 9 (88.9%) patients, postope-ratively. Conclusion:This technique may be an effective method for the repair of nasal septal perforation when the perforation is not located near the nasal dorsum and that its size is 20 m or less in diameter, as the technique offers a cosmetic advantage and produces a satisfactory postoperative outcome by obviating difficulty in intranasal suture.

Background and Objectives:The aims of the current study are to reintroduce a surgical technique for endoscopic removal of the antral portion of antrochoanal polyp (ACP) by powered instrumentation and to determine its eficacy by evaluating the outcome of the patients. Materials and Method:sinus surgery for ACP by the authors surgical technique. Improvements of clinical symptoms and endoscopic and computed tomographic findings were evaluated postoperatively with a follow-up period ranging from 12 to 52 months. All symptom scores on a 100 mm visual analog scale before operation were compared with those obtained at the last visit after operation. Postoperative endoscopic and computed tomographic findings were graded using a three-point scale ranging from 0 to 2. In the surgical technique, the antral portion of ACP was identified through the enlarged ostium under intranasal endoscopy and removed by a blade of powered instrumentation that was inserted through the canine fossa. Results:Symptom scores were all significantly reduced postoperatively. All but one patient showed improvement in clinical symptoms and endoscopic and computed tomographic findings during the follow-up period. There were no major complications specific to this technique. Conclusion:This technique provides an attractive alternative to other methods for removing the antral portion of ACP and is associated with excellent outcomes and the minimal morbidities rate.
