Background: Septoplasty with turbinate surgery is common surgical treatment in patients with septal deviation and chronic hypertrophic rhinitis. The aim of this study was to evaluation objective outcomes of septoplasty with turbinate surgery by analysis of subjective symptom score with objective acoustic rhinometric test before and after surgery, prospectively. Materials and Methods: We reviewed 45 adult patients which were done septoplasty with bilateral turbinectomy or turbinoplasty and followed up at least 3 months by one rhinologist from November 1999 to April 2000, prospectively. We analyzed subjective symptom score, minimal cross-sectional area (MCA), C-notch cross-sectional area, and total volume of both nasal cavity before and after surgery. Correlation test was studied between symptom improvement and acoustic rhinometric results. Results: Twenty nine cases were male and sixteen cases female. The average age was 26.9 year-old (range: 17 to 57 years). There was significantly improvement of symptom score in postoperative 3 months (p<0.05). There was significantly increased C-notch cross-sectional area and total volume in postoperative 3 months. Symptoms improvement were associated with acoustic rhinometric profiles, but, there was not significantly correlation. Conclusion: Septoplasty with turbinate surgery is considered to be effective for nasal obstruction in patients with septal deviation and turbinate hypertrophy. Acoustic rhinometric test is favorable objective test for evaluation of symptom improvement after septal surgery.

Implants for rhinoplasty should ideally be biocompatible and possess long-term stability after implantation. Silicone implants are most widely used for rhinoplasty. However, these implants suffer from problems related to high extrusion and infection rates. To minimize these complications, we propose a novel augmentation rhinoplasty technique using tissue engineering. To demonstrate its feasibility, a nasal-implant-shaped scaffold was designed using commercialized CAD software and fabricated using a Multi-head Deposition System, which is a solid freeform fabrication system that dispenses material. In vitro cell proliferation and chondrogenic differentiation tests were carried out using nasal septal chondrocytes.

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 Objectives: Although polyvinyl acetate ($Merocel^{(R)}$) has been widely used as a packing material after septoplasty, removable nasal packing can increase patient discomfort, local pain, and pressure. Furthermore, the removal of nasal packing has been described as the most uncomfortable and distressing feature associated with septoplasty. The purpose of this study was to investigate the efficacy of polyvinyl acetate with carboxymethyl cellulose sheet ($Rhinocel^{(R)}$) nasal packing on patient subjective symptoms, degree of bleeding, hemostasis, and wound healing following septoplasty. Subjects and Method: Forty patients with nasal septum deviation requiring septoplasty were included. Following surgery, one nasal cavity was packed with $Rhinocel^{(R)}$ and the other one with $Merocel^{(R)}$. Patient subjective symptoms while the packing was in situ, hemostatic properties, pain on removal, degree of bleeding on removal, duration of hemostasis after removal, postoperative wound healing, and the cost of the pack were evaluated. Results: Although the two types of packing materials were equally effective in controlling postoperative bleeding after septoplasty, $Rhinocel^{(R)}$ was significantly more comfortable while in situ and less painful on removal than $Merocel^{(R)}$, which was associated with significantly more bleeding on removal and so more time was needed to control hemorrhage. There was no significant difference in postoperative wound healing or pack cost. Conclusion: The use of $Rhinocel^{(R)}$ after septoplasty has less discomfort, greater patient satisfaction, and less bleeding on removal with no adverse reactions compared to $Merocel^{(R)}$ packing. Therefore, $Rhinocel^{(R)}$ may be a useful packing material after septoplasty.

Purpose: Most nasal bone fractures involve the septum; either or both of the ethmoidal perpendicular plate(EPP) and quadrangular cartilage(QC). Unlocked tension from the underlying quadrangular cartilage and poorly reducted bony septum are obstacles to the successful reduction of nasal bone. So we compared the preliminary outcome of septoplasty as a primary treatment with the untreated septum in nasal bone fractures. Methods: We performed a retrospective study of 215 patients underwent reduction of nasal fracture between January 2002 and February 2008. We graded patients into four groups according to the amount of deviation and direction of force by CT. Our indication for septoplasty and combined procedures was the deviation of EPP or QC over 50% from the midline. We interviewed part of the patients by telephone regarding the subjective esthetic and functional outcomes. Results: Forty five of 215 patients (21 percent) underwent septoplasty and combined procedures (cartilage graft, etc) after the informed consent. Patients who underwent septoplasty significantly satisfied with the outcome of esthetic appearance and nasal patency compared with patients who underwent simple closed reduction despite of having septal deviation over 50 percent from the midline. (p < 0.05) Conclusion: Septal surgery and esthetic consideration shoud be made even in simple nasal reductions. And if CT scans reveal severe deviation of septum, septoplasty should be considered as a primary treatment.

Septal deviations interfere with the nasal airflow and contribute to the deformities in the external appearance of the nose. An aesthetically and functionally satisfactory correction of severe septal deformities often requires temporary intraoperative removal of the septal cartilage for appropriate remodeling. This article describes septoplasty through dorsal approach for the correction of septal deviation. From March 2001 to April 2004, the author performed septoplasty through dorsal approach for the correction of septal deviations on 45 patients, of whom 22 of whom had nasal obstruction. Open rhinoplasty was used for dorsal approach in all patients and operation was performed under the general anesthesia or local anesthesia. The follow-up period of the patients ranged from 3 to 15 months with a mean of 10 months, and postoperative results were quite satisfactory. There was neither incidences of patients' complaints, nor any complications such as hematoma, septal perforation, supratip deformity, or recurrence. And there was some improvement of nasal obstruction in 15 patients. In conclusion, Septoplasty through dorsal approach is an effective method for the correction of septal deviation and improvement of the nasal airway obstruction.

Craniofacial asymmetry was analyzed in 39 patients with complete unilateral cleft lip and palate(UCLP). The samples are devided into three groups nine below 9 years, twenty three from 9 years 1 month to 14 years and seven over 14 years group. Seventeen measurements were obtained from the tracing of PA X-ray cephalometric headfilms to evaluate the asymmetric characteristics and changes accdording to aging in UCLP. The obtained results were as follows. 1. Facial asymmetry in UCLP is variable(1.22-3.47 $mm/^{\circ}$) and the length from midsagitta1 reference line to maxillary 1st molar, to upper central incisor and the length of mandibular ramus showed significant asymmetry 2. Nasal septum and anterior nasal spine were deviated In the cleft side and the lower border of nasal cavity was 1ower in cleft side. 3. The deviation of nasal septum was continued significantly till after 14 years old.

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.
