Purpose: Pnumosinus dilatans is a rare disease that one or more of the paranasal sinuses are dilatated without functional alteration. The most frequently involved sites are frontal and sphenoid sinus. Facial asymmetric contour is the most common signs and nasal obstruction and pain may be combined. The purpose of reconstruction of pneumosinus dilatans is two-fold, to re-establish a permanent pressure equilibrium of sinus and to correct the possible facial deformities. Methods: We present a case of a 24-year-old female with a 7-year history of protrusion of right malar region. Plane radiography and computed tomography detailed an abnormal expansion of the right maxillary sinus without thinning of bony wall, leading to diagnosis of maxillary pneumosinus dilatans. Surgical decompression and maxilloplasty were achieved by ostectomy of anterior wall of maxillary sinus and repositioning of removed bony fragment with miniplate. Results: Post operative course was uneventful without complication and malar height became symmetric by physical and radiologic examination. Conclusion: We corrected successfully pneumosinus dilatans of maxillary sinus by surgical decompression and maxilloplasty. For this case, we reviewed literature related to this topic.

목적 : 접형동에 발생하는 일차성 암은 매우 드물어 전체 부비동 악성종양의 $0.3\%$를 차지한다. 접형동암이 드물게 발생되므로 많은 환자들을 분석하여 얻은 치료결과나 생존기간의 통계가 지금까지도 보고되지 않았다. 이에 본원에서 치료를 시행했던 접형동암 환자 1예의 치료경과를 보고하고자 한다. 증례 보고 : 일부 증례보고들과 소수의 환자들을 대상으로 했던 연구들을 재검토한 한 보고에 따르면 2년 생존율이 $7\%$였다. 본 증례는 접형동암으로 진단된 후 지금까지 29개월동안 생존하고 있다. 또한 척수내 전이는 암환자에서 드문 합병증인데 본 증례에서는 접형동암으로 진단된 후 25개월 만에 갑자기 하지 마비증세와 배뇨곤란을 호소하여 흉추부위를 MRI촬영한 결과 척수내 전이성종양을 3번 4번 흉추부위에서 관찰할 수 있었고 척수공동증을 그 이하부위에 동반하고 있었다. 저자들은 접형동암환자에서 척수공동증을 동반한 척수내 전이소견을 보인 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

Purpose: Maxillary sinus elevation has been widely used to enable insertion of endosseous implants in severely resorbed maxilla. Maxillary sinusitis after this procedure was considered to be the major drawback, therefore, preoperative evaluation of paranasal sinus is considered to be important. In order to evaluate the condition of the sinus, we used Waters' projection. In this study, asymptomatic patients were evaluated by Waters' view, and compared to timing to assess the sinus cavity. Methods: The retrospective study was based on 14 patients who were performed sinus elevation surgery in Seoul National University Dental Hospital. These patients did not show any signs of maxillary sinusitis. These patients were taken Waters' view at preoperative, postoperative 1 day, 3 months, 6 months. In Waters' view, presence of air fluid level, radiopacity of sinus wall, or radiopacity of entire maxillary sinus were evaluated. The density, and sinus dimension changes were assessed using Adobe Photoshop CS5$^{(R)}$ (Adobe Systems Inc., San Jose, CA, USA). Results: Findings of Waters views in patients with clear maxillary sinus at preoperative time were followed by elevated sinus floor with transplanted bone, mucosal swelling, and air fluid level. At postoperative 3 months, and 6 months, the radiographic findings were similar to preoperative state. By contrast, patients with preoperative mucosal swelling, or haziness in sinus cavity showed radiopacity entire sinus in Waters' view. In cases of the patients who were treated with simultaneous treatment to mucosal swelling, good status of sinus cavity were found. Conclusion: Although Waters' projections provide the limited information, and is less sensitive method compared with computed tomography, it is simple, easy, and economical method to assess of maxillary sinus. We suggest using Waters' view as radiographic routine tool for evaluation of sinus condition, especially in the sinus elevation surgery.

부비동내의 이물은 흔히 경험할 수 없는 것으로 그 발생원인은 총기 및 폭발물 사고, 교통 사고 등 외상성 사고로 인한 것과, 부비동 수술시 의료기구의 잔존에 의한 의인성 사고로 나눌 수 있다. 외상성 사고로 인한 부비동내 이물의 발생을 보면 상악동이 가장 흔한 것으로 되어 있고, 전두동, 사골동, 접형동 순으로 되어 있다. 최근 저자 등은 약 8년간의 비폐쇄증 및 농성비루를 주소로 내원하였던 환자에서 좌측 사골동내에 30여 년 이상 체류되었던 1 $\times$ 0.5cm 정도의 탄알파편을 경험하였기에 문헌적 고찰과 함께 보고하는 바이다.

Ossifying fibroma is a rare, benign, fibro-osseous tumor of mesenchymal origin. It develops mainly in the mandible, where it is usually slow growing and asymptomatic, whereas in the maxilla and paranasal sinus, it is more aggressive. The vast majority are located in the posterior region of the mandible; however, ossifying fibroma involving the maxillary sinus is uncommon. It may reach a very large size and cause facial asymmetry. It shows a female predilection, and most cases are seen in the third and fourth decades of life. Radiographically, ossifying fibroma is radiolucent or radiopaque depending on the amount of calcification. Histologically, the tumor consists of a cementum-like or bony mass. Ossifying fibroma shares many histopathologic features with fibrous dysplasia. Their radiographic features may help to separate these entities when pathological differentiation is uncertain. It is important to differentiate ossifying fibroma from fibrous dysplasia. The treatment of ossifying fibroma involves its complete removal using curettage, enucleation, excision, or en bloc resection. This case report presents an unusual case of ossifying fibroma of the maxillary sinus. We describe a Caldwell-Luc operation with a lateral window approach for excision of an ossifying fibroma of the maxillary sinus.

Purpose: This study evaluated maxillary sinus volume changes in military jet aircraft pilot candidates before and after the training program, in comparison with a control group, considering the effects of pressurization, altitude, and total flight hours, through multislice computed tomography. Materials and Methods: Fifteen fighter pilots were evaluated before initiating the training program and after the final approval. The control group consisted of 41 young adults who had not flown during their military career. The volumes of each maxillary sinus were measured individually before and at the end of the training program. Results: When comparing the initial and final volumes in the pilots, a statistically significant increase was observed both in the left and right maxillary sinuses. When evaluating the average total volume of the maxillary sinuses(i.e., the average volume of the right and left maxillary sinuses together), a significant increase in the volume of the maxillary sinuses was observed in the pilot group when compared to the control group. Conclusion: The maxillary sinus volumes in aircraft pilot candidates increased after the 8-month training program. This may be explained by changes in the gravitational force, the expansion of gas, and positive pressure from oxygen masks. This unprecedented investigation among pilots might lead to other investigations considering paranasal sinus alterations in this singular population.

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.

Large cell neuroendocrine carcinoma is a rare epithelial neuroendocrine malignancy and is preferentially located in gastrointestinal tract and pancreas. Cases of large cell neuroendocrine carcinoma have been reported in many other locations, including the thymus, gallbladder, prostate, larynx, salivary glands, nasopharynx, tonsil and mastoid. However, primary sinonasal large cell neuroendocrine carcinoma never have been reported in Korea. We experienced a case of primary large cell neuroendocrine carcinoma arising from left maxillary sinus recently. A 82-year-old male patient presented with nasal obstruction and epistaxis. The biopsy revealed large cell neuroendocrine carcinoma with poor differentiation. After a general evaluation, the patient was staged as cT3N0M0. The patient was treated by combined radiotherapy and chemotherapy. We report this rare case with literature review.

Osteomas are most often located in the femur, tibia, humerus, spine, and talus. They are rare in the skull. Osteomas in the head and neck regions are benign bone neoplasms usually found in the frontoethmoid area. The developmental theory postulates that osteomas develop at the sites of fusion of tissues different embryological origin such as occur at the junction of the embryonic cartilaginous frontal and ethmoid bones. Trauma and infection have also been implicated as causative factors, but many patients with osteoma deny any preceding history of these. Osteomas are usually produce symptoms primary to cosmetic problems and secondary to pressure on adjacent structures. The objects of this study are from a 5-year period of April of 2002 to April of 2007, consisting of 48 male patients and 52 female. There were 33 cases of frontal bone osteomas, 5 cases of madibular bone osteomas, 5 cases of occipital bone osteomas, 6 cases of symptomatic paranasal sinus osteomas, 48 cases of asymptomatic paranasal sinus osteomas, and 3 cases of mastoid osteomas. We reviewed medical records of patients to find out their presentations, diagnostic considerations, therapeutic options, and outcomes. Patients were followed up six months postoperatively on the average. The authors experienced 48 cases of osteoma in the head and neck lesion, which were removed via direct approach or endoscopic approach. The 100 cases who came to the hospital with or without symptoms after diagnosis healed completely without sequelae. During the follow-up periods, excellent functional and cosmetic results were observed with an inconspicuous scar. There was no specific complications related to this procedure. Results of surgery in most cases were satisfied. We discussed the surgical procedure and the characteristics of the osteomas, and we report several cases with the review of literatures.

Objectives The purpose of this study is to examine 33 cases of chronic sinusitis in children who were treated with Korean medicine. Methods Herbal medicine, acupuncture, and nebulizer and laser therapy were used to treat chronic sinusitis, and a plain radiography (paranasal sinus water's view) was used to confirm improvement of the children's sinusitis. Then, the data was classified by sex, age, frequency and duration of common cold, severity of sinusitis, duration of treatment, pattern identification and so on. Results There were 72.7% boys and 27.3% girls. The average age of children is $4.48{\pm}2.18years$. 70% of the children had common cold more than once a month, and 85.1% of the children from the study group had common cold lasting more than a week. The sinusitis severity score ranged from 10 to 200. 81.8% were more than 100. Duration of the treatment was $157.21{\pm}83.4day$, duration of herbal medicine treatment was $79.3{\pm}31.23day$, rate of herbal medicine was $62.12{\pm}29.21%$. The frequency of acupuncture, nebulizer and laser therapy ranged from 1 time to 11 times but was much lower than expected. Conclusions 33 cases of chronic sinusitis in children were treated with Korean medicine, and cure of the illness was confirmed by PNS water's view, and clinical characteristic of the patients with chronic sinusitis was analyzed.
