저자들은 비중격 만곡증으로 잔단받은 22명의 환자들을 대상으로 수술 전후 음향비강통기도 검사를 시행하고 협부와 광부에서 각각 측정된 6개의 계측치들을 비교하여 비중격성형술과 하비갑개 절제술의 효과에 대한 객관적인 평가자료로서 음향비강통기도 검사가 갖는 의의를 연구하였다. We used acoustic rhinometry to evaluate the effectiveness of surgery on nasal septum and turbinate. Twenty two patients with septal deviation and/or inferior turbinate hypertrophy were examined preoperatively and preoperatively by acoustic rhinometry. Six parameters were measured and evaluated statistically. Postoperatively the area at the conchal notch, the area at 4.0cm from the nostril, nasal volume increased significantly. These results suggest that the area at the conchal notch, the area at 4.0cm from the nostril, nasal volume could be useful parameters for the evaluation of the effectiveness for the septal and turbinate surgry.

Purpose: Nasal bone fractures are often classified as minor injury. However, the incidence of posttraumatic nasal deformity remains alarmingly high. It is because of unnoticed septal fracture. This study was conducted to determine the necessity of septoplasty for patients with nasal bone fracture accompanying grade I septal fractures. Methods: Among 105 patients with nasal bone fractures, 52 who had grade I septal fracture were diagnosed based on physical examination and computed tomography. Patients' age ranged from 14 to 65 years (mean 29.25 years), and 35 were male and 17 female. Patients were divided into 2 groups according to surgical treatment methods: patients who underwent closed reduction only (group 1, n=28) and those who underwent simultaneous closed reduction and septoplasty (group 2, n=24). The treatment outcomes were evaluated by comparing changes in nasal airway volume measured by acoustic rhinometry before the surgery, 3 months and 6 months after the surgery according to the timing of surgical repair and surgical treatment methods. Results: Nasal airway volume increased after the surgery by 17.8% in 3 months after the surgery, 25.2% in 6 months in group 1 and by 22.7% in 3 months, 35.8% in 6 months in group 2. The increase in airway volume after the surgery by 26.3% in 3 months after the surgery, 34.2% in 6 months after the surgery in operation within 1 week after trauma and by 12.1% in 3 months, 22.2% in 6 months after the operation later 1 week after trauma. The difference was statistically significant. Three patients in group 1 complained of intermittent nasal obstruction, two of whom showed a decrease in nasal airway volume by acoustic rhinometry. Conclusion: Most patients with nasal bone fractures accompanying grade I septal fractures have been treated with closed reduction in clinical settings. However, the results of this study suggest that septoplasty be performed after a correct diagnosis of septal fracture is made through comprehensive physical examination and computed tomography. Septoplasty is important to obtain more favorable outcomes and reduce complication.

Objectives : Allergic rhinitis is one of the most common allergic diseases. The aim of this study was to evaluate the clincal effect of herbal medicine(Gamitonggue-tang) in patients with allergic rhinitis by using acoustic rhinometry. Methods : A total of 22 individuals with allergic rhinitis who visited the Dept. of Oriental Medical Opthalmology & Otolaryngology & Dermatology of Daegu Hanny Oriental Medical Center from June 1st, 2006 to February 28th, 2007 were included in this study. In this study, they were only treated with Gamitonggue-tang. For 4 weaks the flow resistance of nasal cavity and total nasal volume, nasal minimum cross-sectional area were measured by acoustic rhinometry at the 1st, the 14th and the 28th day. And symptom score of nasal obstruction were recorded. Results : There were no significant differences on sex, age and onset. After treatment(2, 4 weeks) the calculated flow resistance of nasal cavity, total nasal volume and nasal minimum cross-sectional showed no significant changes(p>0.05). But symptom score of nasal obstruction showed significant changes(p<0.05). Conclusions : Considering the above results, treatment with herbal medine(Gamitonggue-tang) could be efficacious in allergic rhinitis. Further studies in other methods are needed.

Background and Objectives The aim of this study was to evaluate clinical characteristics and outcome of septoplasty in patients complaining of paradoxical nasal obstruction. Subjects and Method Medical records of 637 patients who underwent septoplasty from 2011 to 2016 were reviewed retrospectively. One hundred sixty-nine patients whose follow up periods were longer than 3 months were included. These patients were categorized into two groups, the experimental group (paradoxical nasal obstruction) and the control group. We analyzed the degree of nasal obstruction, the sino-nasal outcome test (SNOT)-22 score, which is the sino-nasal outcome, and the minimal cross-sectional area in acoustic rhinometry. The effect of concurrent turbinoplasty was also evaluated. Results Paradoxical nasal obstruction was found in 19 patients (11.2%). Compared to the control group, the degree of mucosal change (both concave and convex side) had no statistical significance. Although the degree of nasal obstruction and SNOT-22 scores were significantly improved after surgery in both groups (p<0.05), the values for the experimental group were slightly increased at 3 months of surgery after having been improved at one month of surgery. In contrast, those values improved steadily over time in the control group. The tendency of psychologic domain scores was significantly different between the two groups (p=0.021). The results of volume reductive turbinoplasty showed that it maintained the improved symptoms better when performed along with septoplasty. Conclusion Although septoplasty showed beneficial effects in patients with paradoxical nasal obstruction, the effect of septoplasty decreased over time. Concurrent volume reductive turbinate surgery maintained the effect of septoplasty in paradoxical nasal obstruction.

한준성,심우섭,배진호,박상희,신영덕,권은정 대한마취통증의학회 2013 Korean Journal of Anesthesiology Vol.65 No.2

Background: During nasotracheal intubation it is important to have proper pretreatment for nasal mucosa constriction and nasal cavity expanding. Nasal packing of epinephrine gauze is widely used as well as xylometazoline. The aim of this study was to compare and evaluate the efficacy of prophylactic intranasal spray of xylometazoline against epinephrine gauze packing in expanding the nasal cavity. Methods: Volunteers (n = 32) in their twenties without nasal disease such as septal deviation or rhinitis were enrolled in the study. The more patent nostril in each subject was measured by acoustic rhinometry as the base value. After intranasal spray of xylometazoline, the same nostril was remeasured by same method. Twenty four hours later, intranasal packing of epinephrine gauze was done and the same treatment was done. Subject preferences about the procedures were asked. Results: There were significant difference among treatments (base value: 0.582 ± 0.164 cm2, xylometazoline spray: 0.793 ± 0.165 cm2, epinephrine gauze packing: 0.990 ± 0.290 cm2) in acoustic rhinometry. While the epinephrine gauze packing showed more efficient mucosa constriction, subjects preferred xylometazoline spray. Conclusions: Even though xylometazoline spray was less effective than epinephrine gauze packing, the simplicity and convenience compensated. In patients undergoing nasotracheal intubation, xylometazoline spray can be an alternative to epinephrine gauze packing.

비강 구조에 대한 임펄스 응답 추정 방법에 관한 연구

In this paper. the new method of estimating impulse response by modified Wiener filter is presented. The modified Wiener filter is composed of the noise-to-signal power ratio so that the bias in modified Wiener filter depends on the power spectrum of input signal and noise. Hence. in estimating impulse response. noise is effectively suppressed at the band where the frequency content of input signal is becoming less and less. Simulation shows that error is less in the presented method than in the conventional method. In experiments using the Acoustic Rhinometry. the presented method can acquire the more exact geometry from the estimated impulse response.

Objectives. Acoustic rhinometry is a rapid, reliable and non-invasive technique for the evaluation of conditions associated with impaired nasal patency. This study aimed to examine the intersession repeatability of acoustic rhinometry measurements of unilateral and combined nasal parameters in a group of healthy volunteers. Methods. Twenty healthy volunteers were studied. In each subject, acoustic rhinometry measurements were performed on five consecutive days, with multiple recordings. Five clinically relevant parameters were measured in each session and the intersession repeatability of these measurements was expressed in terms of mean coefficient of variation, intraclass correlation coefficient and inter-item correlations. Results. Intraclass correlation coefficients showed a high, and greater repeatability over time for all the combined (mean)values compared to the unilateral values. All intraclass correlations for combined values were ≥0.80 confirming almost perfect agreement. All intraclass correlations and inter-item correlations were associated with P<0.001. The mean coefficient of variation was low (<10%) for all but the proximal minimum cross sectional area (MCA1) measurements. Conclusion. Acoustic rhinometry provides highly repeatable measurements of nasal patency, which is best for combined (mean) nasal parameters. This property makes it suitable for use in the diagnosis and follow-up of conditions associated with nasal obstruction, either structural or functional. Objectives.

The upper and lower lateral cartilages provide the key to the lower cartilaginous portion of the nose. Lifting the cartilages is essential procedure for correction of unilateral cleft lip nose deformity. After correction of cleft lip nose deformity, authors used acoustic rhinometry (AR) to compare the lower nasal cavity of cleft side with non-cleft side. AR is a well known new, non-invasive diagnostic technique in which nasal geometry is assessed by means of acoustic reflection. From June 1996 to January 2004, we performed acoustic rhinometric analysis after correction of unilateral cleft lip nose deformity. This study involved 40 children of age ranged from 3 months to 8 years. Subjects were divided into the group of incomplete unilateral cleft lip nose deformity(20 subjects), and the group of complete unilateral cleft lip nose deformity(20 subjects). Results show that lower nasal cavity volume between non-cleft side and cleft side has no difference, and better results were obtained when nasal molding prong was applied at cleft side nostril. The results between incomplete type and complete type have no significant difference. In conclusion, AR is an effective method to calibrate cross sectional area and nasal cavity volume of unilateral cleft lip nose deformity, and furthermore effective in comparing the volume of cleft side with non-cleft side after unilateral cleft lip nose deformity correction with lifting the lower lateral cartilages to the upper lateral cartilages.

Evaluations and treatments of nasal bone fracture have been mainly focused on aesthetic aspect, but nose has an important role as an airway. The purpose of this study was evaluation of nasal bone fractures in the view of nasal obstruction and its improvement after reduction. Acoustic rhinometry was applied to the 77 nasal bone fractured patients who received closed reduction from August 2002 to July 2003 and received closed reduction. This was tested twice, before and 6 days after reduction, for all 77 patients and additional acoustic rhinometry was also possible in 26 patients after 6 months. The analysis of acoustic rhinometry were based on data of minimal cross-sectional area(MCA) according to fracture sites(one side, both side and tip) and septal displacement. Mean MCA for all cases before reduction was $0.43{\pm}0.21cm^2$, which was 19% decrease compared to normal adult data($0.53{\pm}0.12cm^2$). Depending on fracture sites the MCA were $0.45{\pm}0.16cm^2$ for one side fracture, $0.35{\pm}0.18cm^2$ for both side fracture, and $0.42{\pm}0.25cm^2$ for tip fracture. The patients with septal displacement showed more severe obstruction than ones without septal displacement, $0.26{\pm}0.26cm^2$ and $0.46{\pm}0.10cm^2$, respectively. The MCA was improved up to $0.50{\pm}0.22cm^2$ after reduction and showed slight decrease after 6 month($0.48{\pm}0.23cm^2$). Based on the results of this study, nasal bone fracture really caused airway obstruction(19% decrease). Both side fracture showed more profound decrease than one side fracture and septal displacement was an important parameter which causes nasal obstruction. Closed reduction improved MCA by 14% right after reduction, and 11% after 6 month follow up.
