Malignant lymphomas are neoplasms with diffuse proliferation of neoplastic lymphocytes and their precursor cells. Diffuse large B-cell lymphoma, which is a subtype of non-Hodgkin's lymphomas, rarely occurs in the head and neck area and is especially rare in the maxillary sinus. We report a case of a 76-year-old female patient who was referred to the oral and maxillofacial surgery office for evaluation of a dental abscess as a clinical diagnosis. Laboratory tests revealed no signs of inflammation or infection; therefore, incisional biopsy was performed. The final diagnosis was diffuse large B-cell lymphoma in the maxillary sinus. Here we describe this case with a review of relevant literature.

A radical maxillectomy causes a defect of the alveolar bone, gingiva, palate, and orbital floor and causes cosmetical problems and masticatory and phonatory functions. Defect after a radical maxillectomy was reconstructed with skin or dermis graft was introduced, but recently wide resection of the tumor and functional reconstruction with free flap was introduced by several methods. The defect due to radical maxillectomy was reconstructed with scapula, iliac crest, radius. But reconstruction with a fibular osteocutaneous free flap was rarely introduced to defect of radical maxillectomy. The fibular osteocutaneous free flap was firstly introduced by Taylor. The fibular osteocutaneous free flap has several advantages. We experienced the first case of radical maxillectomy and reconstruction with the fibular osteocutaneous free flap, so we reported that case with literatures. The patient has a right maxillary sinus squamous carcinoma (T2N0M0), and performed a radical maxillectomy with right supraomohyoid neck dissection, and reconstruction with fibular osteocutaneous free flap. Donor site morbidity was little, and phonatory and masticatory function were nearly normalized. And cosmetical result was very acceptable.

The maxillary sinus bone graft procedure is one of the predictable and successful treatments for the rehabilitation of atrophic and pneumatized edentulous posterior maxilla. Materials used for maxillary sinus floor augmentation include autogenous bone, allogenic bone, xenogenic bone and alloplastic materials. Among them, autogenous bone grafts still represents 'gold standard'for bone augmentation procedures. We selected the mandibular ramus area as a donor site for the autogenous bone graft because of low donor site morbidity. We performed maxillary sinus bone graft procedures with implant placement using particulated ramal autobone and bovine bone mixture, and got good results. This is a preliminary report of the maxillary sinus bone graft using particulated ramal autobone and bovine bone, requires more long-term follow up and further studies.

Foreign bodies in the paranasal sinuses are not commonly observed. Recently, we have observed an interesting case of metalic foreign body (a fragment of bullet) which remained in the posterior part of the left ethmoid sinus for about 30 years, and report here now with a review of literature.

만성 상악동염은 동점막의 복잡한 변화를 일으키고, 만성증으로 지속되는 비분비물 및 비점막의 염증이 이관에 파급되어 중이에 영향을 미치며 그 치유경과를 늦추게 한다. 저자는 만성 상악동염에서 동점막의 비후정도가 이관 및 중이에 미치는 영향을 알아 보고자, 1986년 1월부터 3월까지 이화여자대학교 의과대학 부속병원 이비인후과에 비폐색 및 비루를 주소로하여 내원한 환자중 만성 상악동염으로 진단된 16세 이상의 성인 환자를 대상으로 검사하였다. 동점막 비후정도에 따라 비정상군을 경도(2~3mm), 중등도(4mm이상), 고도(상악동 전체혼탁) 3군으로나누어 각각 40예를 조사군으로 하고 동점막의 두께가 0~1mm인 경우를 정상대조군으로 하여 40예를 GSI 28 AUTO TYMP를 사용하여 screening audiometry, tympanometry, acoustic reflex threshold (ipsilateral and contralateral)를 시행하여 다음과 같은 결과를 얻었다. 1) 남녀의 비는 1 : 2.6이고 21세에서 30세군이 53예(33.0%)로 가장 많았다. 2) 증상발현기간은 6개월 이내가 42.5%로 가장 많았다. 3) Tympanogram의 분포에서 비정상적 type으로 나오는 비율이 정상군과 비정상군중에서 경도군이 각각 22.5%이었고 중등도군이 30.0%, 고도군이 50.0% 순이었다. 4) 등골근반사역치는 정상군과 비정상군 사이에 차이가 없었다. 5) 등골근무반사율 역시 정상군과 비정상군 사이에 차이가 없었다.

One hundred-ten patients with squamous cell carcinoma of the maxillary antrum treated at the Department of Therapeutic Radiology, Seoul National Unviersity Hospital between February 1979 and September 1986 were retrospectively analyzed. Of these, only 73 patients were eligible for analysis. Forty-one patients were treated with combination of surgery and radiation therapy and 32 patients were treated with radiation therapy alone. The majority of patients had advanced stage (including $47\%\;T_4$ tumor). Overall 5 year survival rate was $40.0\%$. In the radiotherapy alone group,5 year survival rate was $22.1\%$, and in the combined surgery and radiotherapy group,5 year survival rate was $65.3\%$. Of 31 patients who had failures,22 patients ($71.0\%$) had local failures, 6 patients ($19.3\%$) had regional failures and 3 patients ($9.7\%$) had distant metastasis. Planned combined treatment with surgery followed by radiation therapy is an effective modality for carcinoma of the maxillary antrum.

Background and Objectives : Unilateral maxillary sinus lesions are relatively common but may occur in variety of causes. Therefore, accurate diagnosis and appropriate treatment are needed. The aim of this study is to review patients with unilateral maxillary sinus lesion who underwent surgical treatment and to analyze causes and characteristics of unilateral maxillary sinus lesions with literature review. Materials and Methods : A retrospective chart analysis was completed on 318 patients with unilateral maxillary sinus lesions who underwent surgical treatment from January, 2008 through May, 2018. Clinical history and data such as age, sex, symptoms of initial, radiologic and dental finding, operation type were collected from medical record. Results : Patients mean age was 50.7 years with slight male gender dominance. Most common type was sinusitis (42.7%), followed by odontogenic sinusitis (22.3%) and fungal ball (19.5%). In particular, the most common cause of odontogenic sinusitis was post dental surgery such as implant. Middle meatal antrostomy (90.9%) was accounted for a great part of surgery underwent to patients. Patients complained of post nasal discharge (62.9%), nasal obstruction (40.9%) and odor smell(35.2%) most commonly. Periapical lucency (35.8%) was the most common in CT finding followed by implant perforation (17.3%) and oroantral fistula (12.3%) in odontogenic sinusitis. Conclusions : Unilateral maxillary sinus lesions are relatively common, but they are increasing recently with dental procedures such as implant surgery, and serious adverse effects due to malignant tumors or improper treatment may occur, so accurate diagnosis and treatment are needed.

This study is to calculate the proper angle for the optimal image of PNS Water's view on children, comparing and analyzing the PNS Water's projection angles between children and adults at every age. This study randomly selected 50 patients who visited the Medical Center from January to May in 2005, and examined the incidence path of central ray, taking a PNS Water's and skull trans-Lat. view in Water's filming position while attaching a lead ball mark on the Orbit, EAM, and acanthion of the patients's skull. And then, we calculated the incidence angles(Angle A) of the line connected from OML and the petrous ridge to the inferior margin of maxilla on general(random) patients's skull image, following the incidence path of central ray. Finally, we analyzed two pieces of the graphs at ages, developing out the patients' ideal images at PNS Water's filming position taken by a digital camera, and calculating the angle(Angle B) between OML and IP(Image Plate). The angle between OML and IP is about $43^{\circ} in 4-years-old children, which is higher than $37^{\circ}, as age increases the angle decreases, it goes to $37^{\circ} around 30 years of age. That is similar result to maxillary growth period. We can get better quality of Water's image for children when taking the PNS Water's view if we change the projection angles, considering maxillary growth for patients in every age stage.
