Background: Turbinate hypertrophy is one of the common causes of chronic nasal obstruction. In principle, therapeutic guidelines recommend medical treatment. Failure to treat turbinate thickening despite drug therapy may indicate the need for surgery. The main aim of this study was to determine the effect of radiofrequency surgery, among various other surgical procedures, on people with both nasal septal deviation and turbinate hypertrophy. Methods: Among people with nasal deviation who visited the subject hospital between July 2008 to July 2014, 21 people with nasal septal deviation and severe turbinate hypertrophy before their surgery had undergone septoplasty with turbinoplasty using radiofrequency combined with septoplasty. The degree of the turbinate's hypertrophy was appraised in all the patients before and after the surgery using the rhinoscopy, and acoustic rhinometry was objectively carried out. The subjective effect of the turbinoplasty using radiofrequency was explored through the visual analog scale (VAS) score. Results: The degree of contraction of the nasal mucosa after the rhinoscopy changed from Grades 3 and 4 (100%) to Grades 1 and 2 (95.2%) and Grades 3 (4.8%). The minimal cross-sectional area significantly increased from $0.44{\pm}0.07$ to $0.70{\pm}0.07cm^2$ (p<0.05). The nasal cavity volume increased from $4.79{\pm}0.49$ to $6.76{\pm}0.55cm^2$ (p<0.05). The subjective symptoms evaluated with VAS score a year after the surgery significantly improved (p<0.05). Conclusion: Turbinoplasty using Coblator with septoplasty is an effective treatment method because it expands nasal cavity, has a low incidence of complications, subjectively improves symptoms, and has short treatment duration.

Three major physiological functions of nose can be described as air-conditioning, filtering and smelling. Detailed knowledge of airflow characteristics in nasal cavities is essential to understanding of the physiological and pathological aspects of nasal breathing. In our laboratory, a series of experimental investigations have been conducted on the airflows in normal and abnormal nasal cavity models by means of PIV under both constant and periodic flow conditions. In this work, more specifically experimental and numerical results on the surgically modified inferior turbinate model were presented. With the high resolution CT data and a careful treatment of the model surface under the ENT doctor's advice yielded quite sophisticated cavity models for the PIV experiment. Physiological nature of the airflow was discussed in terms of velocity distribution and vortical structure for constant inspirational flow. Since the inferior and middle turbinate are key determinants of nasal airflow, the turbinectomy obviously altered the main stream direction. This phenomenon may cause local changes in physiological function and the flow resistance.

This study was done to analyze the effects of a smear in the nasal cavity against nosocomial Infection. The smear used was mupirocin, and the study centered on infection which constitutes the majority of nosocomial infections called MRSA. The data were collected between March 23 1998 and June 31 of the same year in a university hospital in the Kyongi Province, and is made up of a experimental group of 14 patients who were given nasal cavity smears and a control group of 16 patients who were not given nasal cavity smears. The data were analyzed through frequency and the Chi-square tests and gave forth these results. 1. Of the experimental group 28.6% developed nosocomial infections while 62.5% of the control group developed infections. This difference was significant. 2. In the experimental group, all of the patients developed infections within the first week in the ICU, while 80% of the control group developed infections in the first week and 20% in the second week. The difference was not as marked here. 3. In the experimental group the DM group 66.7% contracted MRSA while 18.2% developed it in the non-DM group showing that the DM group had infection rate was 3.7 times higher than the non-DM groups. In the control group the DM group had a 100% infection rate while 50% of the non-DM group developed it. Overall the DM group's rate infection was 2.4 times higher than the non-DM group. 4. In the experimental group, 37.55% of the patients who had a tracheostomy developed it while 16.7% of the patients who did not have a tracheostomy developed infections. In the control group, 62.5% of the patients who had tracheostomy, and 37.5% of the patients who did not have tracheostomies developed infections. Those who had tracheostomies, and the control group had double the rate contracting infections. From these results we can see that nasal cavity smears are effective against nosocomial infections. In spite of the smears, patients with the diabetes mellitus had a high MRSA infection rate, which requires new alternative treatments.

5 year-old female Siberian husky which was 27 kg had presented with a recurrent rhinitis with chronic discharge and cough. A nasal foreign material had been suggested by a finding of a bone density ($0.3{\times}0.3$ cm) in the left nasal cavity on X-ray and CT-scanning. Soft tissue opacity in frontal sinus and nasal cavity was increased and foreign material was located beside turbinate bone in the left nasal. We found that there was the increase in the number of eosinophil and mast cell by the nasal cytology test. These results mentioned above indicated that the rhinitis by nasal foreign body was suspicious. We decided that the transfrontal rhinotomy could be the proper procedure to approach the material in this case. After rhinotomy, the foreign body and severe sticky discharge were removed. Drain was placed through the hole and into the frontal sinus and nasal cavity which were flushed two times a day for 7 days. The clinical signs such as cough and nasal discharge were shown to be improved in the every visiting for the re-check. On the $40^{th}$ day after surgery, we could confirm that the most of soft tissue density in the frontal sinus and nasal cavity was decreased by CT-scanning. However, foreign body was not identified by histological examination. For the treatment of chronic rhinitis caused by foreign body, the surgical method such as rhinotomy can be applied, when it is difficult to remove it in the guide of the nasal endoscope.

Rhinoliths are foreign bodies composed of mineralised deposits in the nasal cavity that are rarely encountered in routine dental practice. The current report presents a case of a 77-year-old female patient who visited a dental treatment centre for a routine dental check-up and prophylaxis. On the clinical examination, the patient did not report any breathing difficulty, nasal obstruction, or any form of discharge. Panoramic radiography showed a horizontally magnified radiopaque structure in the right nasal fossa region. Cone-beam computed tomography (CBCT) revealed a hyperdense entity with a laminated presentation in the right nasal fossa. The hyperdense entity was diagnosed as a rhinolith based on the radiographic findings. Although the patient was asymptomatic, a referral was made to an ear, nose, and throat surgeon for a further evaluation. This report highlights the importance of CBCT imaging in the diagnosis of soft-tissue calcifications.

Allergic rhinitis is a specific IgE mediated inflammatory disease of the nasal mucosa, characterized by symptoms such as rhinorrhea, nasal congestion, nasal obstruction, nasal and eye itching, and sneezing. The prevalence of allergic rhinitis varies according to country, age, and surveying methods, but it seems to increase worldwide, also in Korea. Prolonged mouth breathing caused by allergic rhinitis can produce muscular and postural alterations, causing alterations on the morphology, position, growth direction of the jaws, and malocclusion. Also, mouth breathing leads to dryness of the mouth, causing various oral diseases; gingivitis, halitosis, inflammation of tonsil, increased risk of dental caries and dental erosion. In dental clinic, using rapid maxillary expansion to persistent allergic rhinitis patients with narrow maxilla can enlarge maxillary dental arch and nasal cavity anatomy, improving nasal breathing and reducing nasal cavity resistance. However, it is desirable to use along with otolaryngologic treatment. Dentists should be aware of the characteristics of allergic rhinitis and its effects on patients, and consider when planning dental treatment.

Inflammatory sinonasal disease was diagnosed in five dogs and two cats with clinical signs of nasal discharge and epistaxis. Survey radiography and CT were performed in all of patients. CT scan of the rostral cranium was performed with a thickness of 2 or 5 mm. Nasal cytology and culture from nasal smear were performed immediately after CT examination. Remarkable increase of opacity in the nasal cavities and frontal sinuses was observed in only 3 cases. On CT images, the cavitating lesions were isodense in nasal cavity (7 cases), frontal sinuses (3 cases), and nasopharynx (2 cases) with destruction of the nasal septum (4 cases), maxillary turbinates (5 cases), maxilla (3 cases), and hard palate (3 cases). The lesions were enhanced after intravenous contrast administration in 5 cases and were not enhanced in 2 cases. Inflammatory cells were observed in nasal cytology. Most of the cultures from nasal smear were bacteria. CT is useful to diagnose sinonasal disease and is more accurate in demonstrating the extent and character of lesions of nasal cavity than radiography.

Because vocal technique is the basis of singing a song beautifully, so this study was undertaken to use the scientific and correct technique in order to get much better musical expressions. Shimadzu X - ray remote control TV system was used for checking the supporting state of diaphragmatic respiration after 5, 10, 15, 20, 25 and 30 sec during phonation in the state of full inhalation between professional singer and non - professional singer. Shimadzu Magnet $nex-{\alpha}$(SMT -50CX/H) was used for examining the scattering state from the resonance of nasal cavity to that of cranial cavity on the basis of diaphragmatic respiration. The results obtained were summerized as follows : 1. The resonance of cranial cavity must be scattered by the energy of diaphragmatic respiration after gathering the foci of the fundamental 5 vowels. 2. while raising the epiglottis, the resonance of nasal cavity must be clearly in order to maintain the resonance of cranial cavity beautifully. 3. We can get musical expressions by maintaining the elasticity of diaphragmatic respiration.

Purpose : To assess the width of the labial alveolar bone of the incisive canal and the width of the incisive canal on spiral computed tomographic images of the anterior portion of the maxilla. Materials and Methods : Study materials included 38 CT scans taken for preoperative planning of implant placement. Axial cross-sectioned image entirely showing the incisive canal was selected and scanned with 600 DPI resolution. The width of the labial alveolar bone of the incisive canal at an orifice to the oral cavity, middle portion, and an orifice to the nasal cavity and the diameter of the incisive canal at the middle portion were determined by two specialist using Digora for Windows 2.1 The statistical analyses were carried out using SPSS 12.0.1. Results : When the maxillary central incisors remained, the mean labial alveolar bone width were $6.81{\pm}1.41mm,\;6.46{\pm}1.33mm$, and $7.91{\pm}1.33mm$. When the maxillary central incisors were missed the mean width were $5.42{\pm}2.20mm,\;6.23{\pm}2.29mm$, and $7.89{\pm}2.13mm$. Conclusions : The labial alveolar bone width at middle portion and an orifice to the nasal cavity were of no statistical significant difference according to presence of the maxillary central incisors (P>0.05). The width between oral cavity and nasal cavity, middle portion and to nasal cavity revealed statistically significant difference (P<0.05).
