1. In oriental medicine, the case of sinusitis can be explained, not only external invasion such as PUNG HAN(wind-cold), PUNG YUL(wind-hot), SHUP YUL(damp-heat), but also functional disorder of internal organ such as spleen(脾), lung(肺), kidney(腎) The western medicine classified the cause of sinusitis as two factors. That is bacterial infection factor-Haemophilus influenza, streptococcus pyogeues, streptococcus pneumonia- and viral infection factor-Rhinovirus, parainfluenza, Echo28, Coxsacki21, Sinusitis is complicated to allergic rhinitis, chronic otitis media purulent, chronic tonsilitis, sinubronchitis. On the condition of nasal septum deformity, turbinates deformity, nasal septum deviation, sinusitis can be developed. the predisposing factors of sinusitis is swimming, air pollution, malnutrition, shortage of immunity.2. According to survey, sinusitis occurred that children from 4 to 12 years old and from 5 to 7 years old occupied 70% 3. From the past history data, they experienced chronic tonsillar hypertropy(20%), otitis media, atopic dermatitis, allergic rhinitis, bronchial asthma, pneumonia, bronchiolitis, chronic sore throat, urticaria, milk allergy in sequence. 4. the symptoms of sinusitis is nasal obstruction, postnasal dripping, purulunt(yellow)or white discharge, cough, nose bleeding in sequence. nasal obstruction take the portion of 95%, postnasal dripping 65%, night time or early morning cough 60%. 5. The suffering period of sinusitis is 6 month minimum, 4 years maximum, most cases are included in a year. The suffering period of children was shorter than adult. 6. Diagnosis depend on inspection of nasal cavity, postnasal dripping, X-ray finding. 75% of patient(15case) showed both maxillary sinusitis, 25%(5cases) showed left or right maxillary sinusitis. 7. Treatment of oriental medicine, consist of Herb-medicine, acupuncture and exposing of Lazer beam. Kamihyunggyeyungyotang(加味荊芥蓮翹湯) is administered mainly as the medical therapy, Kamigwaghyangjeungkisan(加味藿香正氣散) Kimizwakwieum(加味左歸飮), Kamihyangsosan(加味香蘇散) is administered for a additional symptoms which occurred by influenza recurrence. Kamijeonxibackchulsan(加味錢氏白朮散) is administered to treat gastro-intestine trouble patients who have sinusitis. 8. The period of treatment is varied with patient conditions and X-ray finding. The minimal period is 35days, maximal period is 202days. So it took about 86days in average and about 50% of patient(10cases) is recovered in one or two month.

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.

Supernumerary teeth are teeth added to the normal complement of teeth. They are most often found in the maxillary anterior region. Most supernumerary teeth in the maxillary anterior region have complications, such as impaction or malposition of permanent teeth, formation of diastema, cysts, and eruption into the nasal cavity or into the oral cavity. These complications have influence on deciding the treatment and its prognosis is depends on how these complications are treated. In clinical studies, it has been found that the removal of supernumerary teeth before the age of 5 years resulted in significant fewer eruption problems of the permanent tooth compared to removal at 7 years of age or later. However, such an early removal may leads to serious consequences of tooth development and behavioral management of patients. Therefore clinicians must consider complications of supernumerary tooth when deciding the time of removal. These cases report five-type of complication associated with supernumerary tooth such as diastema, delayed eruption, external root resorption, migration into nasal cavity and cyst formation.

Purpose: The radial forearm fasciocutaneous free flap is currently considered as the ideal free flap for reconstruction of mucosal and soft tissue defects of the palate. But the availability of stably attached oral and nasal mucosal lining is needed. In addition to this, for better operation field, operating convenience and esthetics, we planned a prelaminated radial forearm free flap. Methods: A 64-year-old male patient was admitted due to a $4{\times}4.5cm$ full through defect in the middle of the hard palate caused by peripheral T cell lymphoma with actinomycosis. In the first stage, the radial forearm flap was elevated, tailored to fit the hard palate defect, and then it positioned up-side down with split thickness skin graft. Two weeks later, the prelaminated radial forearm free flap was re-elevated and transferred to the palatal defect. One side covered with grafted skin was used to line the nasal cavity, and the other side (the cutaneous portion of the radial forearm flap) was used to line the oral cavity. Results: The prelamination procedure was relatively easy and useful. The skin graft was well taken to the flap. After 2nd stage operation, the flap survived uneventfully. There was no prolapse of the inset flap into the oral cavity and the cutaneous portion of the flap was mucosalized. The procedure was very successful and the patient can enjoy normal rigid diet and speech. Conclusion: The use of prelaminated radial forearm free flap for hard palate reconstruction is an excellent method to restore oral function. Based upon the result of this case, microvascular free flap transfer with prelaminated procedure is a valid alternative to the prosthetic obturator for palatal defect that provides an improved quality of life. It should be considered as an integral component of head and neck cancer therapy and rehabilitation.

Velopharyngeal insufficiency is defined as a status in which nasal cavity and oral cavity can not be sepa-rated when speaking, swallowing by any reason. It has been treated by palatorrhaphy, pharyn-geal flap, local flap, free flap etc. When the size of the defect is small, it can be restored by palatorrhaphy, pharyngeal flap etc. But they are not proper for treatment of the large size of defect. In that case, local flap and free flap are more beneficial. Although large defect can be restored by free flap technique, but it is very complex, time-consuming and may bring about esthetical, functional complications of donor site. Buccinator myomucosal flap is a kind of local flap and reported for the first time by Bozola et al in 1989 and it has become a useful way for reconstruction of large intraoral defect. Authors experienced the use of buccinators myomucosal flap for treating secondary velopharyngeal insufficiency with large soft palate defect and obtained good result. So we report the case with literature reviews.

Basaloid squamous cell carcinoma(BSCC) is uncommon and distinct variant of squamous cell carcinoma that arises mostly in the upper aerodigestive tract and aggressive, high grade tumor with an increased tendency to be deeply invasive, multifocal, and metastatic even at the initial presentation. The typical microscopic features of carcinoma with a basaloid pattern in intimate association with a squamous component helps in diagnosis of this tumour. Since Wain's report in 1986, BSCC of oral cavity, the palate, floor of the mouth, nasopharynx, oropharynx and mastoid region have been reported. However, BSCC in the nasal cavity or in the paranasal sinuses is rare and there are few reports in the Korean literature. We had experienced a case of basaloid squamous cell carcinoma that occurred in the left maxillary sinus of 72-year-old woman and reported with review of the clinical and pathologic features from the literature.

Drug delivery in human upper airway was studied by the numerical simulation of oral airflow. We created an anatomically accurate upper airway model from CT scan data by using a medical image processing software (Mimics). The upper airway was composed of oral cavity, pharynx, larynx, trachea, and second generations of branches. Thin sliced CT data and meticulous refinement of model surface under the ENT doctor's advice provided more sophisticated nasal cavity models. With this 3D upper airway models, numerical simulation was conducted by ANSYS/FLUENT. The steady inspiratory airflows in that model was solved numerically for the case of flow rate of 250 mL/s with drug-laden spray(Q= 20, 40, 60 mL/s). Optimal parameters for mechanical drug aerosol targeting of predetermined areas was to be computed, for a given representative upper airways. From numerical flow visualization results, as flow-rate of drug-laden spray increases, the drag spray residue in oral cavity was increased and the distribution of drug spray in trachea and branches became more homogeneous.

In order to understand the effects of all-trans-RA on palate development, RA was injected into the abdominal cavity of pregnant mice and then the embryos were taken in the following days and analyzed morphologically as well as molecular biologically. When RA was administered at the stage of E11 or E15, the overall craniofacial development was retarded. The length from jaw to eye was shortened, compared to that of normal group. When the E11 embryos were exposed to RA, cleft lip was also found along with the cleft palate. In vitro palate culture experiment also revealed that RA caused cleft palate. When RT-PCR was performed, early stage administration of RA at E11 inhibited the upregulation of Hoxa7 expression at E15 through E17. Whereas in control group, high level of Hoxa7 expression was detected in the palate of E15 to E17. In the case of Bax, the expression was decreased from E16, while remaining constant in control group. When TUNEL analysis was performed following the RA treatment at E15, TUNEL positive cells were detected in the mesenchymal cells as well as epithelial cells of palatal shelves of E16 and in E17 embryos. Whereas in normal control, TUNEL positive cells were observed mostly at the epithelium around the nasal cavity and oral cavity where rugae is made. These results altogether indicate that exposure to RA during palate development causes facial deformity including cleft palate and cleft lip by modulating the expression of homeotic genes such as Hoxa7 as well as an apoptosis-related gene, Bax, and thus malregulating the apoptosis.
