A 10-year old female Yorkshire terrier with nasal discharge and swelling was referred to the local animal hospital. Abnormal mass of right nasal cavity was detected in physical examination and radiography. According to the radiographs of the head, there was an evidence of bony destruction in right nose. Oronasal fistula was detected in right maxillary canine teeth. After surgical excision, the sample of nasal mass was refereed to Pathology Department of Veterinary Medicine in Jeju National University. Grossly, the enlarged mass was soft and 3 ${\times}$ 3 cm in size. Histopathologically, the neoplastic mass was composed of tubular to tubulopapillary structures which were lined by single to 6~7 layers of cuboidal to ciliated columnar cells. These neoplastic cells showed invasive tendency to adjacent normal parenchyma. They had uniform, round to oval nuclei, cytoplasm with small vacuoles and indistinct cellular margin. The number of mitotic figures was varied in different areas, ranged from 0 to 4 per high power field. Necrotic foci and infiltration of inflammatory cells including neutrophils, lymphocytes, and plasma cells also presented in the mass. Immunohistochemically, the neoplastic cells demonstrated strong positive reaction for cytokeratin (CK) 18 but were negative for CK 7 and 8. Based on the gross, histopathology and immunohistochemistry, this mass was diagnosed as nasal adenocarcinoma originated from respiratory epithelium.

The Functional endoscopic sinus surgery through transnasal approach is a common modality of treatment for disorders of the nasal cavity, paranasal air sinuses as well as cranial cavity. The olfactory fossa (OF) is located along the superior aspect of cribriform plate which varies in shape and depth. This variable measurement of the depth of OF is mostly responsible for greater risk of intracranial infiltration during endoscopic procedures in and around the nasal cavity. The morphology of frontal and ethmoid sinus (ES) vary from simple to complex. This cadaveric study is planned to improve the ability of the otolaryngologist, radiologist to understand the possible morphological variations and plan steps of less invasive "precision surgery" to have a safe and complication free procedures. A total of 37 human head regions were included in the study. For classification of OF, Modified Kero's classification was used. The size, shape and cells of frontal and ES were noted. We found, type II (60.8%) OF was more common followed by type I (29.7%) than type III (9.5%). The shape of frontal sinus was comma shaped (55.4%) followed by oval (18.9%) than irregular (16.2%). Most common two cells type of ES was seen in 50.0% of both anterior and posterior ES. Out of 74 ES, 8.1% of Onodi cells and 14.9% of agger nasi cells were seen.

Background Packing after closed reduction of a nasal bone fracture causes inconvenient nasal obstruction in patients. We packed the superior meatus with Vaseline gauze to support the nasal bone, and packed the middle nasal meatus with a Doyle Combo Splint consisting of an airway tube, a silastic sheet, and an expandable sponge to reduce the inconvenience. In addition, we aimed to objectively identify whether this method not only enables nasal respiration but also sufficiently supports the reduced nasal bone. Methods Nasal ventilation was measured via spirometry 1 day before surgery and compared to 1 day after surgery. To compare support of the reduced nasal bone by the 2 methods, 2 plastic surgeons assessed the displacementon X-rays taken after the surgery and after removing the packing. The extent of nasal obstruction, dry mouth, sleep disturbance, headache, and swallowing difficulty were compared with visual analog scales (VAS) on a pre-discharge survey. Results In the experimental group, the nasal respiration volume 1 day after surgery remained at $71.3%{\pm}6.84%$ on average compared to 1 day prior to surgery. Support of the reduced bone in the experimental group ($2.80{\pm}0.4$) was not significantly different from the control group ($2.88{\pm}0.33$). The VAS scores for all survey items were lower in the experimental group than in the control group, where a lower score indicated a lower level of inconvenience. Conclusions The nasal cavity packing described here maintained objective measures of nasal respiration and supported the reduced bone similar to conventional methods. Maintaining nasal respiration reduced the inconvenience to patients, which demonstrates that this packing method is useful.

Nasal polyps were apparently common in many parts of the world and treated for nearly three thousand years. Nasal polyps are round, smooth, soft, semi-translucent, yellow or pale glistening structures, usually attached to the nasal or sinus mucosa by a relatively narrow stalk or pedicle. The incidence of nasal polyps is increased in patients with atopic diseases; it varies from 15% to 25% and now increased using allergy therapy for nasal polyposis treatment. Sinusitis is an inflammation of the mucous membranes of the sinuses. Many agents can cause an inflammatory response, including organisms such as bacteria and viruses, physical and chemical trauma, and antigen antibody reactions. The role of antigen antibody interactions (allergy) in simusitis is not completely understood ; however, patients with allergic rhinitis and nasal polyps have a high incidence of sinusitis. Recently authors have experienced two cured cases of nasal polyposis combined with chronic sinusitis by allergy therapy, that cases were treated only allergy thereapy after Caldwell Luc operation with ethmoidectomy and polypectomy. At now cases were not recur of nasal polyps and nasal symptoms. So the cases were reported with a brief review of literature.

In addition to respiration, the nose performs three other major physiological functions-air-conditioning, filtering, and smelling. On the basis of our experience in experimental investigations of nasal airflows in normal and abnormal nasal cavity models, airflows in the normal model and three artificially deformed models, which simulate the results of surgical treatments (inferior turbinectomy), are investigated by PIV and CFD. The left cavities of all three models are normal, and the right cavities are modified as follows: (1) excision of the head of the inferior turbinate, (2) resection of the lower fifth of the inferior turbinate, and (3) resection of almost the entire inferior turbinate. The use of high-resolution CT data and careful surface rendering of three-dimensional computer models with the help of an ENT doctor provide more sophisticated nasal cavity models. Nasal airflows for both normal and deformed cases are also compared.

Objectives This study was designed to analyze the characteristics of craniofacial hyperhidrosis and palmar/plantar hyperhidrosis by nasal endoscopy and body composition test. Methods The study sample consisted of 20 and 22 patients with craniofacial hyperhidrosis and palmar/plantar hyperhidrosis, respectively, who answered questionnaires and underwent nasal endoscopy and body composition test. The questionnaires estimated the quality of life by Dermatology Life Quality Index score (DLQI), and the degree of obesity was evaluated using body mass index (BMI), percent body fat (PBF), and waist-hip ratio (WHR). The state of nasal cavity was evaluated by color, humidity, and swelling of the mucous membranes, and runny nose. Results BMI, PBF, and WHR were higher in patients with craniofacial hyperhidrosis than in patients with palmar/plantar hyperhidrosis. Rhinitis score was not significantly different between craniofacial hyperhidrosis and palmar/plantar hyperhidrosis. There was a positive correlation between rhinitis score and DLQI. Conclusions The degree of obesity was higher in patients with craniofacial hyperhidrosis than in those with palmar/plantar hyperhidrosis. The state of nasal cavity was not significantly different between craniofacial hyperhidrosis and palmar/plantar hyperhidrosis, but was associated with quality of life of hyperhidrosis patients.

The lateral rhinotomy signifies only an incision and not on operation and a lateral rhinotomy incision with osteotomy of the nasal bones provides access to the entire nasal cavity and maxillary, ethmoid, and sphenoid sinuses as well as the frontal sinus if the floor is removed, permitting removal of benign lesions at these sites and en bloc resection of the ethmoid labyrinth and the party wall between the nasal cavity and antrum with infiltrating tumors. The authors treated a tumor patient and a midfacial bone fracture patient via lateral rhinotomy approach and had a good result. So we report the cases with literature review.

The sphenopalatine ganglion lies behind the middle nasal concha in the sphenopalatine foramen which connects the fossa to the nasal cavity. It has sympathetic and parasympathetic fibers as well as sensory fibers which innervate the nasal cavity, palate and nasopharynx. Current indications for blockade of the sphenopalatine ganglion include the management of migraine, cluster headache and a variety of facial neuralgias. Blockage of this ganglion can be attempted when more conservative treatments have failed. If the pain relief gained through the procedure is of short duration and the blockage needs to be repeated frequently, then radiofrequency thermocoagulation should be considered. Since the sphenopalatine ganglion lies close to the maxillary nerve, neurolytics can cause facial dysesthesia, radiofrequency thermocoagulation is the preferred method for ganglionotomy. Radiofrequency thermocoagulation of the sphenopalatine ganglion was done for 3 patients who suffered from postherpetic neuralgia, cluster headache, atypical facial pain respectively. Good results were obtained with the exception of the patient suffering from atypical facial pain. Although we were concerned about complications such as epistaxis, none were encountered. However it should be noted that caution must be exercised when repeatedly redirecting the cannula in the sphenopalatine fossa as serious bleeding and pronounced facial swelling may result.

The mucociliary system is one of the most important airway defense mechanisms, and knowledge of the ciliary beat frequency(CBF) is important in the understanding of this system. Using a laser light scattering method and fiber optic probe, we developed a simple and practical instrument for real-time in vivo measurements of CBF of cells in human nasal cavity. From the ciliated epithelium cells in an anterior end of middle terminator in nasal cavity, the signals of ciliary movement are transferred into a PC and analyzed by a autoregressive(AR) power spectrum. The mean CBF of 8 normal subjects was $7.1{\pm}1.1$(Hz). This instrument provided a convenient and reliable method of studying the mucociliary activity in the respiratory tract.

The present study reports a case of inverted papilloma of the nasal cavity and infiltrating into the maxillary sinus. Inverted papilloma is an uncommon and locally aggressive benign tumor of the sinonasal region. The patient, 51year-old male, presented with unilateral nasal obstruction and periodic swelling on the palate without pain. Enhanced CT scan revealed a heterogeneously enhancing solid mass in the nasal cavity and infiltrating into the right maxillary sinus, as well as an incidental, secondarily infected residual cyst in the periapical area of the right maxillary canine. The sinonasal mass was revealed as an inverted papilloma on histopathologic examination. (Korean J Oral Maxillofac Radiol2009; 39: 103-7)
