Background : Nasal pyramid fractures accompanied by saddle nose deformities are not easily corrected by closed reduction. We used an absorbable plate as a perpendicular strut to support the collapsed "keystone area" and obtained good results. Methods : Between September 2008 and June 2011, 18 patients who had nasal pyramid fractures with saddle nose deformities underwent surgery. Pre- and postoperative facial computed tomographic images and photographs were taken to estimate outcomes. The operative technique included the mucoperichondrial dissection of the nasal septum, insertion of an absorbable plate prepared to an appropriate length to support the "keystone area", and fixation of the absorbable plate strut to the cartilaginous septum. Results : Functional and esthetic outcomes were satisfactory in all patients. Eleven patients assessed the postoperative appearance of the external nose as 'markedly improved' and 7 patients as 'improved'. The 5 surgeons scored the results as a mean of 4.5 on a 5-point scale. Conclusions : The use of an absorbable plate as a perpendicular strut requires no additional procedures because the plate is gradually absorbed. The mechanical strength provided by a buttress between the "keystone area" and the maxillary crest lasts for a long time before the strut is absorbed.

The nose is an important landmark of the face and its shape and beauty is of significant concern. The columella is the subunit between the two nostrils that provides support and projection to the nasal tip and has functional role in nostrils, as well as aesthetic. Ethiology for columellar absence or deficiency is diverse, and it is one of the most complex nasal subunits to reconstruct because of its narrow horizontal dimension, its tenuous vascularity and limited availability of adjacent tissue. We present a patient with columellar, membranous septum and upper lip defect, due to oncological resection. The lip reconstruction was designed using advancement of two upper lip edges with the technique of webster perialar/nasocheek advancement. However, the perialar/nasocheek tissue which is usually discarded was used as inferiorly based skin flaps to reconstruct the membranous septum, columellar skin and nasal vestibule lining. Rib cage cartilage graft was used as columellar strut for support. At 1-year follow-up, the patient has good nasal contour and projection. Scaring of the columella is very subtle. This is a versatile way for successful reconstruction of a columella and large central facial defect in one-stage operation. It is a method which provides very satisfactory aesthetic result with minimum patient morbidity and discomfort.

Background Nasal tip support is an essential consideration for rhinoplasty in East Asians. There are many techniques to improve tip projection, and among them, the columellar strut is the most popular technique. However, the conventional design is less supportive for rotating the tip. The amount of harvestable septal cartilage is relatively small in East Asians. For an optimal outcome, we propose an L-shaped design for applying the columellar strut. Methods To evaluate the anthropometric outcomes, the change in nasal tip projection and the columella-labial angle were analyzed by comparing preoperative and postoperative photographs. The anthropometric study group consisted of 25 patients who underwent the same operative technique of an L-shaped strut graft using septal cartilage and were followed up for more than 9 months. Results There were statistically significant differences between the preoperative and postoperative values in the nasal tip projection ratio and columella-labial angle. We did not observe any complications directly related to the L-shaped columellar strut in the anthropometric study group. Conclusions The L-shaped columellar strut has advantages not only in the controlling of tip projection and rotation, but in that it needs a smaller amount of cartilage compared to the conventional septal extension graft. It can therefore be an alternative technique for nasal tip plasty when there is an insufficient amount of harvestable septal cartilage.

There are various surgical methods for reconstruction of the nasal defect. Among them, there is some difference in the choosing the proper reconstruction method according to defect size and position. When the defect involved the tip, the columella, and the alar, the local flaps may be preferred, because they can provide sufficient amount of tissue. However, the composite grafts from the ear have been effectively used in reconstructions of smaller sized defects of the columella and ala. We excised total external nose because of squamous cell carcinoma on the nasal tip, columella, and nasal septum. We reconstructed the nasal tip, both alae, and columella with forehead flap. After division of the regional flap, we found partial necrosis of the columella and narrowness of the nostril. So, we used chondrocutaneous auricular composite grafts for reconstruction of the columella and both nostrils. We used the file-folder designed auricular composite graft for reconstruction of columella and the wedge shaped ear helical composite grafts for widening of nostrils. 6 months later, there were no significant problems, except some mismatched dark color in the grafted alar tissues. Here, we report a successful reconstruction of large nasal defect using combined two different reconstructive methods.

Since the first report of a nasal septal abscess (NSA) from a dental origin (1920), six articles have been published in the English literature to date. The most common cause of NSA is an infection of the nasal septal hematoma after trauma. This is a report of an uncommon cause of NSA with a dental origin. A PubMed search performed regardless of year and country using the terms ("nasal septal abscess") OR ("nasal septum abscess") initially yielded 229 articles. After screening, seven articles (eight patients) were selected. Addition of two related articles produced a total of nine articles (10 patients) to be included. The age of the included patients ranged from 7 to 69 years (mean, 32.82 years; standard deviation, ±23.86 years). The sex composition was as followed: males (n=7; 63.6%), females (n=4; 36.4%). Dental histories were various: periapical lesions, caries, extraction, endodontic therapy, and cystic lesions. The maxillary incisor dominated as the tooth of origin. Early diagnosis and treatment of NSAs are important to avoid not only facial deformity, but also severe complications (e.g., intracranial infection). If NSA is suspected in patients without facial trauma, the possibility of a dental origin, especially from the maxillary incisor area, should be considered.

Schwannomas, which originate from Schwann cells in the peripheral nervous system, are slowg-rowing and uncommon benign tumors. Most schwannomas (90%) occur in isolation, and multiple occurrences are a characteristic feature of neurofibromas. Schwannomas of the nose and nasal tip are particularly unusual. Although a few cases of schwannomas of the sinusoidal tract and nasal septum have been reported, schwannomas arising from the nasal dorsum area and tip are extremely rare. Sensory abnormalities are also a very rare symptom. We excised a schwannoma on the nasal dorsum through direct incision and a schwannoma on the nasal tip through open rhinoplasty. No postoperative complications involving recurrence, hematoma, or infection occurred. The possibility of neurological changes should be considered in cases of an abnormality in the peripheral nervous system. Schwannoma must be kept in mind as a possible cause of neurological changes localized to a specific dermatome, and should always be considered in the differential diagnosis of a mass on the nose.

비강의 3 가지 생리학적 주요기능은 공기조절, filtering, 후각기능이다. 비강 내 공기유동특성에 대한 지식은 비강 호흡의 생,병리학적 측면을 기반으로 한다. 본 연구실에서는 정상 및 변형된 비강 모델 내 유동에 관하여 일정유량 및 주기유동 하에서 다양한 PIV 실험들을 진행해 왔다. 비대칭 비강을 가진 환자들 중에 일부는 고통을 느끼거나 불편함을 호소하는 반면 그렇지 않은 환자들도 있다. 이 원인을 밝히기 위하여 비중격이 휘어진 비대칭 모델에 대하여 PIV 및 수치해석적인 연구를 진행하였다. 이를 위하여 이비인후과 의사로부터 모델에 관한 CT 데이터를 제공받아 PIV 및 수치해석을 통해 호기 및 흡기시의 RMS 값 및 속도 분포를 얻었다. 모델에 따라 좌우 유량이 크게 다른 것을 확인할 수 있었고 이것이 고통을 느끼는 원인중에 하나가 될 수 있다.
