Purpose : A retrospective analysis was performed to investigate the proper management of maxillary sinus carcinoma. Materials and Methods : Authors analysed 33 patients of squamous cell carcinoma of maxillary sinus treated at Chonnam University Hospital from January 1986 to December 1992. There were 24 men and 9 women with median age of 55 years. According to AJCC TNM system of 1988, a patient of T2, 10 patients of T3 and 22 patients of T4 were availalbe, respectively. Cervical lymph node metastases was observed in 5 patients(N 1;4/33, N2b; 1/33). Patients were classified as 3 groups according to management method. The first group, named as 'FAR' (16 patients), was consisted or preoperative intra-arterial chemotherapy with 5-fluorouracil(5-FU;mean of total dosage;3078mg) through the superficial temporal artery with concurrent radiation(mean dose delivered:3433cGy, daily 180-200cGy) and vitamin A(50,000 IU daily), and followed by total maxillectomy and postoperative radiation therapy(mean dose;2351cGy). The second group, named as 'SR'(7 patients), was consisted of total maxillectomy followed by postoperative radiation therapy(mean dose 5920 cGy). The third group, named as 'R'(6 patients), was treated with radiation alone(mean dose;7164cGy). Kaplan-Meier product limit method was used for survival analysis and Mantel-Cox test was performed for significance of survival difference between two groups. Results : Local recurrence free survival rate in the end of 2 year was $100\%$, $50\%$ and $0\%$ in FAR, SR and R group, respectively. Disease free survival rate in 2 years was $88.9\%$, $28.0\%$ and $0\%$ in FAR, SR and R group, respectively. Overall survival rate in 2 years was $88.9\%$, $40\%$ and $50\%$ in FAR, SR and R group, respectively. There were statistically significant difference between FAR and SR or FAR and R group in their local recurrence free, disease free and overall survial rates. But difference of each survival rate between SR and R group was not significant. Conclusion : In this study FAR group revealed better results than SR or R group. In the future prospective randomized study is in need.

Purpose : This study was to evaluate the effectiveness of preoperative radiotherapy in maxillary sinus cancer. Materials and Methods : A retrospective analysis was done for 42 patients with maxillary sinus cancer who were treated with radiation with or without surgery from April 1986 to September 1996. There were 27 male and 15 female patients. Patients' age ranged from 24 to 75 years (median 56 years). Stage distribution showed 2 in T2, 19 in T3, and 21 in T4 lesions The histologic type was squamous cell carcinoma in 38, undifferentiated carcinoma in 1, transitional cell carcinoma in 1, and adenoid cystic carcinoma in 2 patients. All patients were treated with radiation initially with a dosage range of 50.4-70.2 Gy (median 70.2 Gy) before further evaluation of remnant disease. Eleven patients were given induction chemotherapy (2cycles of 5-fluorouracil and cisplatin) concurrently with radiotherapy. Six to eight weeks after radiotherapy with or without chemotherapy computerized tomography (CT) of paranasal sinus was taken to evaluate remnant disease. If the CT finding showed remnant disease, a Caldwell-Luc procedure was done to get the specimen of suspicious lesions. A radical maxillectomy was done if the specimen was proven to contain malignancy. In contrast periodic follow-up examination was done without any radical surgery if the tissue showed only granulation tissue. Follow-up period ranged from 3 to 92 months with a median 16 months. Results : Nine (21.4$\%$) patients showed complete response (CR) and 33 patients (78.6$\%$) showed persistent disease (PER) to initial radiotherapy. Among the 9 CR patients, 7 patients had no evidence of disease (NED), 1 patient had local failure, and 1 patient had regional failure. Among 33 PER patients, salvage total maxillectomy was done in 10 patients, and the surgery was not feasible or refused in 23 patients. Following the salvage radical surgery, 2 patients were NED and 8 patients were PER status. Overall and disease- free survival rate at 5 years was 23.1$\%$ and 16.7$\%$, respectively. The only factors associated with the overall survival rate was the response to radiotherapy (P<0.01). Conclusion : The only factors associated with the overall survival rate was the response to radiotherapy. We could omit a radical mutilating surgery by preoperative irradiation in 7 of 42 patients (21.4$\%$) so as to preserve their facial integrity.

An advanced maxillary sinus cancer requires an extensive ablation that results an extensive facial deformity, including a skin defect. Reconstruction has to be considered in a radical maxillectomy, especially with skin defect may be accomplished in one stage with a microsurgical free transfer of a latissimus dorsi flap. A man of right maxillary sinus cancer, squamous cell carcinoma, 47 years old of age, had soft tissue invasion of the cheek region. He underwent a radical maxillectomy with extensive skin excision. The maxillectomy and skin defects were reconstructed with the double skin island latissimus dorsi myocutaneous free flap. The cosmetic result and the functional outcome of the nose were thought to be considerably satisfied.

Malignant tumors of the paranasal sinuses are quite rare entity, with maxillary neoplasms accounting for less than 1 percent of all head and neck malignancies. When considering the paranasal sinuses alone, 77 percent of cancers arise in the maxillary sinuses. There is no situation more frustrating than the management of the patients with chronic facial pain due to cancer. The initial step in managing patients with cancer pain is the use of oncologic therapy in the form of radiotherapy, surgery, chemotherapy, alone or combined, either to effect a cure or decrease the size of the tumor and thus decrease or eliminate the pain. When oncologic therapy is ineffective in providing relief, the pain must be treated by one or more of the followings: Systemic analgesics and adjuvant drugs, psychologic techniques of analgesia, neurostimulating techniques, neuroablative surgical procedures, regional analgesia with local anesthetics or neurolytic blocks. An 82-year old patient had severe pain of the orbital and infraorbital region due to squamous cell carcinoma of the maxillary sinus. We successfully treated this patient with the percutaneous retrogasserian ethanol gangliolysis by a H$\ddot{a}$rtel approach, and the analgesia lasts until the death of the patient.

The authors reviewed 95 cases(46 men and 49 women) of the orbital tumors diagnosed histopathologically at the Department of Ophthalmology, Yeungnam University Hospital from March 1984 through August 1994. Seventy-five cases of benign tumors were found evenly in all decades, but twenty cases of malignant tumors were noticed more frequently in 1st, 6th, and 7th decades. The frequency of benign orbital tumors was in this order; dermolipoma(21%, 20 cases), dermoid cyst(11.6%, 11 cases), mucocele(8.4%, 8 cases), lipoma(7.4%, 7 cases) and pleomorphic adenoma(5.3%, 5 cases). Of malignant orbital tumors, the frequency was in this order; retinoblastoma(3 cases), malignant melanoma(2 cases), sebaceous carcinoma(2 cases), and maxillary sinus carcinoma(2 cases). Malignant orbital tumors of 8 expired patients were revealed as secondary or metastatic tumors.

Irradiated 88 patients of Maxillary Sinus Carcinoma at Yonsei Cancer Center for 10years between 1971 and 1980 were retrospectively analysed. The majority of patients had very advanced disease(87.5% of $T_3\;and\;T_4$) and 17% of cervical lymph node involvement. 80.6% of all patients were epidermoid type. In 44 cases(50%), irradiation alone was performed. 28 cases(32%) of postoperative radiation after incomplete surgery and the remaining 16 cases(18%) of postoperative radiation after radical surgery were done. The majority of patients except 6 cases had irradiation a dose between 60Gy and 80Gy in 30-40 fractions over 6-8 weeks. The actuarial overall 3 and 5 year survival rate were 362% and 26%, respectively. The actuarial 5 year survival rate for 44 cases of radiation alone group was 14.1%, The actuarial 5 year survival rate for 28 cases of incomplete surgery and postoperative radiation group and 16 cases of radical surgery and postoperative radiation group were 312% and 67.4% respectively. In the actuarial 5 year survival rate according to the stage, stage II, III and IV were 79.5%, 20.9% and 0%. In recent, for the improvement of survival rate of advanced Maxillary Sinus Carcinoma at Yonsei Cancer Center, combined multidisplinary or trimodal treatment modality have been applied and in near time the more excellent results expect to be analyse.

Purpose : Maxillary sinus cancers are usually locally advanced, and involve the structures around sinus, but the regional lymphatic spread is uncommon. Therefore, the local control of these cancers is important for their cure. We reviewed our experience of 55 patients with squamous cell carcinomas of the maxillary sinus, treated with radiation therapy, and looked for the role of radiation therapy in maxillary sinus cancers. Materials and Methods : Between November 1982 and October 1999, 55 patients with squamous cell carcinomas of the maxillary sinus underwent either radiation therapy only, or combined with surgery or with concurrent chemoradlation therapy. All patients were restaged according to the 1997 AJCC staging systems. The T classifications of the tumors of the patients were as follows 1.8$\%$ (1/55) for 72, 81.8$\%$ (45/55) for 73 and 16.4$\%$ (9/55) for 74. Thirteen patients were diagnosed with lymph node involvement. With the surgical procedures, 12 patients were managed by biopsy only, 21 were resected by FESS (funclienal endoscopic sinus surgery) and 22 by partial/medical/total rnaxillectomies. The details of the treatments were as follows 8 patients were treated with radiation therapy only, 17 with a combination of FESS and radiation therapy, 22 with a combination of a maxillectomy and radiation therapy, 4 with a combination of preoperative radiation therapy and surgery, and 4 with concurrent chemoradiation therapy. The mean follow-up for all patients was 25 months, ranging from 2.8 to 125 months. Results : The 4-year local control and survival rates for all Patients were 45.5 and 33.3$\%$, respectively. The 4-year local control and suHival rates, due to the extent of surgery, were as follows 32.1, and 21.4$\%$ for biopsy; 41.9, and 31.7$\%$ for FESS; and 56.8, and 52.7$\%$ for maxillectomy, respectively. Twenty-nine (52.7$\%$) patients were not cured, and of these 29 patients, 23 (79.3$\%$) patients had a iocal recurrence following treatment. Conclusions :This study has shown that the major failure sites following treatment to be the local regions, and that the completeness of surgery was important for improving the local control and survival of patients with squamous cell carcinoma of the maxillary sinus.

Purpose : Maxillary sinus cancers usually are locally advanced and involve the structures around sinus. It is uncommon for this cancer to spread to the regional lymph-nodes. For this reason, local control is of paramount important for cure. A policy of combined treatment is generally accepted as the most effective means of enhancing cure rartes. This paper reports our experience of a retrospective study of 31 Patients treated with radiation therapy alone and combination therapy of surgery and radiation. Materials and Methods: Between July 1974 and January 1992, 47 Patients with maxillary sinus cancers underwent either radiation therpay alone or combination therapy of surgery and radiation. Of these, only 31 patients were eligible for analysis. The distribution of clinical stage by the AJCC system was $26\%$(8/31) for T2 and $74\%$(23/31) for T3 and T4. Eight patients had palpable lymphadenopathy at diagnosis. Primary site was treated by Cobalt-60 radiation therapy using through a $45^{\circ}$ wedge-pair technique. Elective neck irradiation was not routinely given. Of these 8 patients, the six who had clinically involved nodes were treated with definite radiation therapy. The other two patients had received radical neck dissection. The twenty-two patients were treated with radiation alone and 9 patients were treated with combination radiation therapy, The RT alone patients with RT dose less than 60 Gy were 9 and those above 60 Gy were 13. Results : The overall 5 year survival rate was $23.8\%$. The 5 year survival rate by T-stage was $60.5\%$ and $7.9\%$ for T2 and T3,4, respectively. Statistical significance was found by T-stage(p<0.005). The 5 year survival rate by N-stage was $30\%$ for N (-) and $8.3\%$ for N(+), but statistically no significant difference was seen(p${\geq}$0.1). The 5 year survival rate for RT alone and combination RT was $22.5\%$ and $27.4\%$, respectively. The primary local control rate was $65\%$ (20/31). Conclusion : This study did not show significant difference in survival between RT alone and combination RT. There is still much controversy with regard to which treatment is optimum. Improved RT technique and development of multimodality treatment are essential to improve the local control and the survival rate in patients with advanced maxillary sinus cancer.

Background: Cancers of the maxillary sinuses are not common and are the most difficult head and neck malignancies in which to make an early diagnosis. Objectives: This reports was conducted to evaluated the efficacy of combination therapy and the relationship between the treatment modalities and their outcome of maxillary sinus cancers. Materials and Methods: We retrospectively analyzed a clinical datas of 46 patients who were treated at the department of Otolaryngology-Head and Neck Surgery. The Catholic University of Korea over 10 years between 1987 and 1996. Results: According to AJCC TNM system, 35 patients presented with $T_4$, 10 with $T_3$, one with T1. Two patients were treated with radiotherapy alone, 4 patients with chemotherapy alone, 17 patients with radiotherapy and chemotherapy, 23 patients with combination of surgery, radiotherapy and chemotherapy. The overall 5 years survival rate for combination therapy group were 57%, but 23 patients treated with the other treatment modalities all died within 2 years except two cases with chemotherapy and radiotherapy or radiotherapy alone. There was a statistical trend for better survival and local control in those patients treated with combination therapy than others(p<0.05). Conclusion: The results of this study suggest that it may be possible to acheive better results with aggressive combination treatment including surgery in advanced cases and to avoid orbital excentration in patients with orbital invasion.
