Purpose: In most cases of nasal bone fracture, closed reduction with internal or external splint fixation approach is selected. However, because of indiscriminate insertion of the internal splint without considering of anatomical difference or deformity, insufficient fixation happens frequently that need additional fixation. Therefore, we suggest a new method for providing adequate support in reduced nasal bone by carving $Merocel^{(R)}$ that is fixed for the anatomical structure. Method: Closed reduction and internal fixation with carved $Merocel^{(R)}$ was performed in 15 nasal bone fracture patients from March, 2010 to July, 2010. Each patient was evaluated by physical examination, facial photographic check, simple X-ray, and computerized tomography. On the first day post-operation, location of packing and amount of reduction were checked by follow up X-ray and computerized tomography. In addition, patients' symptoms were evaluated. During the 3-month post-op follow up at out-patient clinic, operator, 2 doctors in training and one assistant performed the objective evaluations by physical examination on nasal dorsal hump, nasal deviation, nasal depression, nasal breath difficulty, and nasal airway obstruction. A survey of subjective patients' satisfaction in 4-stages was also performed. Results: The results of follow-up computerized tomography of the 15 patients revealed that 11 patients had good reduced state. Three patients with combined maxillary frontal process fracture had over reductions. A survey performed on the first day post-operation showed that 14 of 15 patients answered that their current symptoms were more than tolerable. At the 3-month follow-up physical exam, one case had a dorsal hump. However, there were no nasal deviations, nasal depressions, nasal breath difficulties, or nasal airway obstructions. Twelve of the 15 patients answered more than moderate on the 3-month survey. Conclusion: Intranasal packing after carving the $Merocel^{(R)}$ considering anatomical structure is a new effective method to promote proper-reduction, maintain stability, and minimize patients' symptoms by addition of a simple procedure.

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.

A study on the absorption mechanism of cefixime(CF), an oral ${\alpha}-amino$ group deficient cephalosporin antibiotic, has been undertaken through the rat jejunum and nasal cavity using an in situ simultaneous perfusion technique developed in our laboratory. CF was well absorbed in the jejunum and nasal cavity of rats at pH 5.0, but not at pH 7.0. CF absorption was studied over four orders of magnitude in concentration to determine saturability. Disappearance of CF in the perfusate followed first-order kinetics at all tested concentrations. The apparent first-order absorption rate constant was found to be dependent on the concentration over the range of $0.1\;mM{\sim}3\;mM$ in the jejunum and nasal cavity of rats. Inhibitors were added to determine the competitive inhibition of CF absorption. The presence of L-tyrosine, L-phenylalanine, alanine-alanine, glycine-glycine and cefadroxil produced the significant inhibition of CF absorption in the nasal cavity and jejunum. However, there was no evidence of the inhibition in the presence of cefazolin. In addition, The CF absorption in the nasal cavity and jejunum was inhibited significantly by ouabain and 2,4-dinitrophenol(DNP). This study suggested that CF is absorbed across the rat nasal cavity and jejunum by carrier-mediated transport mechanism and energy consuming system.

As the number of people who have undergone augmentation rhinoplasty has increased recently, nasal fractures are becoming more common after rhinoplasty. A silicone implant can affect the nasal fracture pattern, but there is no significant difference in treatment methods commonly. A 28-year-old female who had undergone augmentation visited our clinic with a nasal fracture. Computed tomography revealed that the silicone implant was sandwiched between the intact nasal bones with fractured bone fragments. In this case, open reduction was inevitable and a new silicone implant was inserted after reduction. Migration of the silicone implant beneath the nasal bone is a very rare phenomenon, but its accurate prevention and diagnosis is important because a closed reduction is impossible.

Purpose: The nasal bone fracture is the most common type of facial bone fracture. In making a diagnosis, physical findings are much more important than the simple radiologic findings. Facial bone CAT scan can provide the accurate diagnosis and the correct location of nasal bone fractures, so it can be lessoned with proper intervention. The aim of this study was to evaluate the usefulness of facial bone CAT scan in the diagnosis of nasal bone fractures. Methods: The medical records and facial bone CAT scan of 45 patients clinically suspected nasal bone fracture but was not diagnosed on simple radiologic findings were analyzed. Results: All of the 45 patients were confirmed as nasal bone fractures in the facial bone CAT scan. The most common cause of fracture was assault. The mean age was 23.2 years. Physical findings were tenderness (100%), swelling(93.3%), epistaxis(66.6%), deviation (42.2 %), external wound(17.7%) and crepitus(4.4%) in order. Conclusions: It was concluded that the simple radiologic findings can not be conclusive, where the physical findings indicate a suspected nasal bone fracture. The facial bone CAT scan was more reliable for the correct diagnosis and follow-on treatment.

A female unknown aged Yorkshire terrier, weighing 3.5 kg with nasal discharge, left facial swelling and severe inflammation was referred to Veterinary Medical Teaching Hospital, Seoul National University. Radiographic findings were lytic change and soft tissue swelling of left zygomatic process and increased radiopacity of nasal cavity. In computed tomography, turbinate bone destruction was observed as well as lytic change of left zygomatic process and left maxilla indicating aggressive lesion. Then 3-dimensional reconstruction was also performed. Biopsy of tissue mass revealed it as squamous cell carcinoma. For this patient, euthanasia was performed guarded prognosis. Generally, tumors of the nasal cavity in dogs account for approximately 1 % to 2% of all neoplasms. The prevalence of these tumors increased with age and exposure to the ultraviolet. About two thirds of all nasal tumors are malignant tumors such as squamous cell carcinoma and adenocarcinoma. As these tumors of nasal cavity are locally invasive, and external beam radiotherapy is the current treatment of choice. Unfortunately, diagnosis of these tumors often occurs late in the course of disease, resulting in a poor prognosis for outcome in many patients. It is considered that computed tomography could be used as an aid modality for the exact evaluation of extend and degree of bone lysis of nasal cavity and metastasis.

The challenges of successful nasal reconstruction, which are related to the anatomical complexity of the region, have been extensively studied. Revisional operations are often required to achieve proper nasal reconstruction, with results resembling the premorbid nasal status. This is necessary to ensure the quality of life of skin cancer patients. Fundamental nasal reconstruction requires both proper soft tissue coverage and proper function. However, earlier studies in the field primarily focused on the functional aspect of nose reconstruction, although the cosmetic aspect is also an important factor to consider. In response to this need, many recent studies on nose reconstruction have proposed various refinement strategies to improve aesthetic satisfaction. Most plastic surgeons accept the nasal aesthetic subunit principle as a standard for nasal reconstruction. This review outlines the commonly used surgical refinement options and management strategies for postoperative complications based on the subunit principle. In patients with nasal defects, a proper technical strategy might help minimize revision operations and optimize the long-term results.

A 14-year-old girl had a midfacial trauma event caused by hitting against an opening door and experienced discomfort and swelling of the columella and upper lip. Physical examination revealed mild tenderness on light palpation without any discomfort with upper lip movement. A computed tomography scan of the maxillofacial bones with three-dimensional reconstruction showed a fracture of the anterior nasal spine with obvious leftward displacement, mild-deviation of the caudal aspect of the nasal septum, and no sign of nasal bone fracture. Open reduction and internal fixation was performed with regard to aesthetic and functional concerns, including nasal septum deviation. The postoperative course was uneventful, and healing proceeded normally without complications. Herein, we emphasize the importance of differential diagnosis of isolated anterior nasal spine fractures in patients with midfacial trauma and clinicians' strategic decision-making in treatment modalities.
