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.

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.

Background & Objectives : Nasal resistance which is halfly responsible for airway resistance is known to be influenced by hypoxia, hypercapnia, exercise, pregnancy, alcohol, ammonia and smoking. Smoking is a common part of our sociocultural environment and we have many a times been introduced to its various adverse effects, which have usually been more focused on lung problems. The purpose of this study is to determine any relationship between smoking and nasal resistance and to evaluate it's effective sites. Materials and Methods : Acoustic rhinometry was performed in 25 smokers and 25 nonsmokers who had no nasal symptoms nor abnormal rhinoscopic findings, and used an acoustic rhinometry to measure the distance from nose-piece to the C-notch, cross sectional area at the C-notch, and volume of the nasal cavity from nose-piece to 7cm. The authors compared the data between the two groups. Results : The cross sectional area at the C-notch was significantly decreased(p<0.05) in smoking group. The distance to the C-notch and the volume of nasal cavity were decreased likely in smoking group but there were no significant difference(p>0.05). Conclusion : Smoking reduced the cross sectional area at the C-notch, so increased the nasal resistance. The underlying mechanisms seems to be decreased nasal mucosal reactivity and congestion of the nasal mucosa. The authors believe there should follow more studies on pathophysiologic mechanisms and the histopathologic changes which involve the effect of smoking on nasal structures.

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.

Background/Aims: A catheter is inserted through the nasal cavity during high-resolution esophageal manometry (HRM), which may cause adverse events such as pain or epistaxis. Despite these possible safety considerations, studies on this subject are very limited. We aimed to investigate the usefulness of nasal cavity evaluation before HRM to reduce the risk of adverse events and test failure. Methods: Patients who underwent HRM after consultation with the ear-nose-throat department for nasal evaluation were retrospectively enrolled between December 2021 and May 2022. The included patients had a previous history of sinonasal disease or surgery or had subjective nasal discomfort. All patients answered the Sino-Nasal Outcome Test (SNOT-22) questionnaire, and subjective nasal discomfort was scored using a visual analog scale. Nasal endoscopy and acoustic rhinometry were performed for disease evaluation and volumetric assessment. Results: The analysis included 22 patients with a mean age of 58.9 years. The mean SNOT-22 score was 24.2, and 16 patients (72.7%) complained of subjective nasal obstruction. The HRM catheter was successfully inserted in 20 patients (90.9%), without any significant adverse events. The objective measurement outcomes of acoustic rhinometry and sinus endoscopy did not always correspond to subjective symptoms. Narrowed nasal airways unresponsive to decongestants were observed in two patients with failed catheter insertion. Conclusions: To reduce the risk of adverse events and test failure during HRM, a site-specific questionnaire to evaluate nasal obstruction might be helpful. When nasal obstruction is suspected, objective nasal cavity evaluation could be recommended for the safe and successful performance of HRM.

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.

Background : The rhinomanometry and acoustic rhinometry can assess e nasal passage dynamically and statically Recently, analytic methods such as nasometer and sound spectrogram are gaining wide attention to evaluate the nasality objectively. Objectives : firstly to determine if ere was a relationship between the new methods and nasal airway resistance, and secondly to establish if the measurement of nasalance and sound spectrum could be used as an alternative to rhinomanometry and acoustic rhinometry. Materials and Methods : Thirty two patients who underwent either septoplasty and turbinectomy for nasal obstruction were studied. And their ages ranged form 15 to 45 years, with an average of 26.1 years. The rhinomanometry, nasometer, sound spectrogram were performed at preoperative and postoperative 4 weeks day. Results : After operation, subjective symptoms and rhinomanometric results were significantly improved but nasalance and slope of nana, mama and mamma passage had not meningful change. The significnat changes were noted in nasalance and first nasal formant frequency of nasal consonant of velum(angang). Conclusion : Nasometer and sound spectrogram had a limitation for the measure of nasal patency.

Background and Purpose : Allergic rhinitis is a well-known, relatively controllable chronic disease. Although a number of methods for treating allergic rhinitis have been tried, many patients have not been satisfied with their treatment. Therefore, this study tried to evaluate the effect of a cooperative system of Oriental and Western medicine and to develop a new diagnosis protocol for treatment of allergic rhinitis. Methods : We measured improvement rate and acoustic rhinometry after the allergeninduction test and performed a filter paper test as a nonspecific hypersensitivity test with 60 patients who are allergic to house dust mite. Patients were divided into two groups, one treated with Western medicine only and one treated with both Western and Oriental herbal medicine. For the group with Western medicine only, antihistamine for one week and local steroid medicine for two weeks were prescribed. For the group with combined medicine, Oriental herbal medicine was prescribed according to the patient s constitution, along with Western medicine. After all treatments, the above tests were re-performed and the improvement rate was compared. Results and Conclusion : We observed better results in the group treated with both Western and Oriental herbal medicines, comparing improvement rate and the alteration of total nasal volume through acoustic rhinometry after the allergen induction test. In the filter paper test, there was no significant difference between the two groups. In conclusion, we showed the additive effect of Oriental herbal medicine without any severe side effects compared with treatment with Western medicine only. In this study, we set only two patient groups, but further study is required to create various experimental groups and compare among them. We suggest that it might enhance understanding of the improved effect of Oriental herbal medicine in the therapy of allergic rhinitis.

Background and Objectives : With the development of computerized systems, an objective evaluation methods of nasal speech and nasal geometry have become readily available by means of a simple, noninvasive technique. In this study, we assessed the nasality, nasal formant, nasal volume and nasal area in patients with hypertrophic rhinitis before and after turbinate surgery. Material and Method : With the nasometer, we measured nasalance, which reflects the ratio of acoustic energy output of nasal sounds from the nasal and oral cavities. With CSL 4300B, we measured nasal formants. We used acoustic rhinometer to measure nasal area and nasal volume. Postoperative changes of above factors were compared with preoperative values. Paired t-test and Pearson's correlation were used for statistical analysis. Results : The first nasal formant frequency, nasalance scores of three passages(baby, mamma and rabbit passages), minimal cross sectional area(MCA) of narrow side, nasal volume of narrow side and nasal volume of wide side had increased significantly after turbinate surgery (p <0.05). The MCA and nasal volume of narrow side and MCA of wide side showed significant correlation with nasalance score of rabbit passage and baby passage showed significant correlation with nasal volume of narrow side(p<0.05). Conclusion : There were significant increases in nasalance scores, first nasal formant frequency, MCA and nasal volume after turbinate surgery. Thus, we must consider the possibility of voice changes postoperatively in professional voice users.

1999년 11월에서 2000년 4월까지 본 교실에서 비중격 성형술과 하비갑개 절제술 혹은 하비갑개 성형술을 시행 받고 3개월이상 추적 관찰이 가능하였던 45명의 성인환자를 대상으로 비중격 성형술 및 하비갑개 수술의 결과를 전향적으로 분석하였다. 수술 전 증상접수는 코막힘이 가장 높았으며 수술 후 전체적으로 모든 증상에서 통계학적으로 의미 있게 호전되었다(p<0.05). 수술 전 후의 음향비강통기도 검사에서 비강수축전의 경우에서 최소비강단면적은 큰 변화가 없었으나, C-절혼 면적과 비강체적은 의미 있게 증가되었다. 또한 증상의 호전도와 음향비강통기도 검사치의 변화와는 통계학적 연관성이 없었으나, 증상이 호전됨에 따라 최소비강단면적, C-절혼 면적, 비강체적이 증가하는 경향을 볼 수 있었다. 결론적으로 바중격 성형술 및 하비갑개 수술 후 결과 판정방법으로서 수술 전 후의 환자의 주관적인 증상을 접수화하여 어느 정도 객관성을 부여하였으며 수술 전 후의 음향비강통기도 검사를 이용하여 음향비장통기도 검사결과를 구하고 이를 바탕으로 증상접수의 호전도와 음향비강통기도 검사결과를 비교 분석함으로써 증상의 호전을 객관적으로 증명하였다.
