  • The septal extension graft is a very useful method of controlling nasal lengthening and tip projection, rotation, and shape by fixing a graft to the septum, which leads to a strong supporting structure. Enhancing graft stability is important for better long-term outcomes and minimizing complications or relapse, and even more efficient application of these methods is needed for East Asians who lack enough cartilage to be harvested in addition to possessing a weak cartilage framework. In this paper, the methods for overcoming the drawbacks of the septal extension graft, such as instability, a fixed tip, and insufficiency of cartilage, are presented, and the applications of each method for greater satisfaction with surgical outcomes are also discussed.

  • The present experiment was carried out 1) to study the developmental topography of GnRH neuronal system and 2) to characterize the cellular localization of GnRH neurons in the prenatal brain development of the rat. At embryonic day (I) 14.5, immunoreactive cell bodies of GnRH were first seen in the nasal septum and in the ganglion terminate located in the ventral protion of the caudal olfactory bulb. Two days later (E 16.5), GnRH-containing neurons were observed at the level of olfactory tubercle and diagonal band of Broca, which is the first appearance in the intracerebral region. From 118.5, the topographic pattern of immunoreactive GnRH perikarya was similar to that of adult rats. The present data suggest that GnRH neurons were originated from the nasal septum and gradually extended to the hvpothalamic regions with increasing fetal age.

  • Allergic rhinitis is a growing tendency to increase. Following this tendency, allergic rhinitis is lively studied also in Korean oriental medicine. Bupleuri Radix (BR) has been used for many inflammatory diseases, but experimental backgrounds are not enough to treat allergic rhinitis. So in this study, effects of BR on OVA-induced allergic rhinitis model of BALB/c mice were examined. Thirty two BALB/c mice are equally devided into four groups; control group, OVA group, OVA+BR group, OVA+Cet group. The OVA, OVA+BR and OVA+Cet groups were induced allergic rhinitis by sensitizing to OVA. And then saline solution included BR (10.6 mg/kg body weight) was administered to the OVA+BR group orally. The number of nasal rubbing and nasal sneezing was evaluated for 10 days and later serological and histological changes were analyzed. Serological analysis included the serum levels of cytokines and chemokines (IL-4, IL-5, IL-12, MCP-1, MIP-2), total IgE and OVA-specific IgE levels in serum. Histological analysis included thickness of nasal septum, eosinophil counts changes of nasal mucosa, infiltration of eosinophil in nasal mucosa and histological changes of nasal mucosa. The number of nasal rubbing and nasal sneezing was significantly decreased in the OVA+BR group. The serum levels of IL-4, IL-5, MCP-1, MIP-2 were significantly decreased in the OVA+BR group but the serum levels of IL-1β had not significance. Total IgE and OVA-specific IgE levels in serum were decreased in the OVA+BR group, but total IgE levels in serum had only significance. Thickness of nasal septum, eosinophil counts of nasal mucosa and infiltration of eosinophil in nasal mucosa were significantly decreased in the OVA+BR group. From the results of this study, we think that BR has an effect on improvement of allergic rhinitis by improving nasal rubbing and nasal sneezing, reducing histological changes of nasal mucosa and infiltration of eosinophil in nasal mucosa, inhibiting increasing of the serum levels of cytokines, chemokines and total IgE.

  • A 39 kg, 7-year-old male Labrador Retriever dog with a 3-month history of epistaxis, sneezing, and nasal discharge was referred to the Veterinary Medical Center of the Tokyo University. On the plain X-ray and computed tomography (CT) of the head showed increased density of the soft tissue in the left nasal cavity and the tumor infiltrated to nasal septum. The tumor mass removed by rhinotomy. Histopathological examination of the mass revealed adenocarcinoma. Four weeks after the surgery, the radiation therapy was performed twice a week for f weeks. 4 months after surgery, the dog had a recurrence in nasal cavity and administered carboplatin 300 mg/$m^2$ twice. However, the tumor had no response to chemotherapy, additional surgery and additional radiation therapy, and the dog was euthanized at the owner's request. At necropsy, metastatic proliferation was confirmed in the lung, lymph nodes and nasal cavity.

  • Congenital facial cleft is a rare entity and appears along by the line of different processes of the facial development. An isolated cleft of the nose has been reported not often in the literature. We treated a patient with an isolated nasal cleft associated with undefined cranial anomaly. On 3D CT scan was seen a bony cleft traversing the pyriform aperture lateral to the anterior nasal spine. The nasal septum and frontal process of the maxilla were intact. There also was found bilateral bony defects in the frontal bone and bilateral frontal boss. The nasal cleft and frontal defect and boss were corrected by two stages: anterior two-third of the cranial vault with bilateral frontal boss was remodeled at the age of two years and the nasal cleft was repaired with a local rotation flap at age 3.

  • A neutered male, 8-year-old, Pekingese, weighing 4.3 kg with a history of anorexia, sneezing, nasal discharge, and epistaxis for one month was referred. Soft tissue swelling around the nasal bone and small defects of the hard palate with a tiny round dark red mass were found on physical examination. The laboratory tests represented mild leukocytosis. On skull radiographs, soft tissue swelling and osteolytic change of the incisor bone, nasal bone, and maxilla were found. On computed tomography scan images, there was soft tissue attenuating opacity with calcified spots in the bilateral nasal cavities and frontal sinuses. Loss of nasal turbinate pattern and nasal septum was found. And destruction of the insicor bone, nasal bone, maxilla, hard palate, perpendicular palatine bone, and cribriform plate were identified. Nasal malignant melanoma was confirmed by nasal biopsy.

  • Background: This report describes the authors' experience of "melting" septal cartilage after placement of a septal extension graft in a nasopharyngeal cancer patient that had been previously undergone radiation therapy, and provides a review of the literature. Methods: Electronic medical records were used to obtain details of the patient's clinical history. Results: A 32-year-old woman, who had previously undergone radiotherapy for nasopharyngeal cancer, visited our department to for rhinoplasty. Rhinoplasty was performed using a septal extension graft to raise the nasal tip (first operation). Five days after surgery, it was found that the septal extension graft was melting without any signs of infection, that is, the graft had softened, lost elasticity, thinned, and partially disappeared without any sign of infection at 5 days, and thus, the nasal tip was reconstructed with conchal cartilage (second operation). Five months after surgery, it was found that almost all septal cartilage had disappeared without any sign of infection, and thus, the entire nasal septum was reconstructed using 2-mm costal cartilage and an onlay graft was used for tip augmentation (third operation). Conclusions: After cartilage has been exposed to radiotherapy, its patency should be viewed with suspicion. Further studies are needed for determine the mechanism responsible for cartilage damage after radiotherapy.

  • Deviated nose deformities have always been a surgical challenge, and it is essential to achieve both functional and esthetic improvements. Various techniques have evolved over time to correct deviated noses but no one method applies in all cases. Successful correction requires a complete understanding of the various surgical techniques and concepts, including the three-dimensional nasal structure and the time-related changes to surgically-treated noses.

  • A 6-year-old spayed female Turkish Angora cat presented with sneezing, nasal discharge, and decreased appetite lasting for 21 days. Skull radiography revealed slightly increased density of soft tissue in the left nasal cavity. Computed tomography (CT) scan revealed an extensive mass with nasal septum destruction and moderate contrast enhancement in the left nasal cavity. After surgical biopsy, histopathological examination confirmed that the mass was an infiltrative round cell neoplasm, composed of sheets of large neoplastic cells. Immunohistochemical analysis revealed that most of the neoplastic cells were strongly positive for CD79a and weakly positive for PAX5. Additionally, numerous mature lymphocytes were found to be positive for CD3. This is the first reported case of nasal diffuse large B-cell lymphoma (DLBCL) in a Turkish Angora cat in Korea.
