상악암의 치료에는 일반적으로 수술요법과 방사선요법이 단독 또는 복합적으로 시행되어 왔다. 항암화학요법과 면역요법의 발전과 더불어 병용요법이 소개되었으며, 상악암에 대한 병용요법은 수술요법과 방사선요법 및 국소동주 화학요법을 병행하고 있다. 본 연구에서는 상악암에 대한 병용요법의 효과를 알아보기 위하여, 상악암으로 진단된 환자에서 Morita법을 약간 변형한 병용요법으로 치료하고 추적관찰이 가능하였던 24례를 대상으로 임상적 및 병리조직학적으로 비교 분석하였다. 병용요법에 의해 5년생존율이 66%로 향상되었으며, 상악전적출술의 필요성이 감소되었다. 상악암에 대한 병용요법은 기존의 광범위한 수술적 치료방법과는 달리 악안면의 형태 및 기능 보존을 목적으로 선택될 수 있는 치료방법의 하나인 것으로 생각된다.

Nine cases of maxillary sinus aspergillosis during a period from February of 1992 to June of 2000 were investigated to analyze the clinical, radiologic and pathologic features. Maxillary sinus aspergillosis is rare disease, but it was increasing tendency with overuse antibiotics, steroid hormones, and anticancer agents. Aspergillosis of the maxillary sinus may occur as a chronic disease in an otherwise healthy person. The clinical features of maxillary sinus aspergillosis were similar to the non-fungal, chronic sinusitis. Intrasinus calcification is known to be a characteristic feature of maxillary sinus aspergillosis. It is suggested that excess root filling materials containing zinc oxide in the maxillary sinus could favour the formation of a local, non-invasive maxillary sinus aspergillosis. And this "dental" model of pathogenensis of maxillary sinus aspergillosis is an alternative to the widely accepted concept of spore inhalation and "aero-genic" pathogenensis of maxillary sinus aspergillosis. The radical surgery such as Caldwell-Luc operation was one of the most effective treatment modalities. Our results of this study indicate that maxillary sinus aspergillosis might occur mainly in healthy individuals rather than debilitating patients. It could efficiently treated with radical surgery alone without the antifungal agents. 4 cases were suspected to be related with teeth extraction and endodontic treatment. There were no recurrence in all cases.

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.

Maxillary cancer is usually detected late, and the majority of patients have advanced($T_3\;or\;T_4$) diseases at the first diagnosis. It invades outside the maxillary antrum, superiorly the orbit, ethmoid sinus and the anterior cranial base, anteriorly the facial skin. If the cancer extends through the posterior antral wall, the pterygoid plates, pterygoid muscles and infratemporal fossa are to be involved that make the conventional maxillectomy impossible to remove all the involved structures in infratemporal fossa completely. So, more extensive surgical apprdoach is necessary. We report surgical experience using infratemporal fossa approach(lateral facial approach) in four cases of maxillary cancer and one case of hard palate cancer which extends through the posterior antral wall and involving pterygoid muscles, pterygoid plates and temporalis muscle.

A retrospective analysis was performed to ascertain the relationship between the treatment modalities and their treatment results. From July 1980 to June 1993, 115 patients with squamous cell carcinoma of the maxillary sinus were: treated at the Department of Radiation Oncology, Yonsei Cancer Center, Yonsei University. There were 88 men and 27 women with median age of 57 years. According to AJCC TNM system of 1992. eight patients of T2, 54 patients of T3 and 53 patients of T4 were available, respectively. Cervical lymph node metastases at diagnosis was observed in 11 patients. 87 patients were treated with radiotherapy and 28 patients were treated with combination of surgery and radiotherapy. The overall 5 year survival rate was 32 %, patients that were treated with radiotherapy alone had a 5 year survival rate 24.3 % and patients who were treated with combination of surgery and radiation therapy had a 5 year survival rate of 52.8 % (p<0.05). Combination of surgery and radiotherapy resulted in a better treatment modality for squamous cell carcinoma of the maxillary sinus. Improved radiotherapy technique and development of multimodality treatment are needed to improve the local control and the survival rate in patients with advanced maxillary sinus carcinoma.

Purpose: The objective of this study was to evaluate the outcomes of using the free flap in the reconstruction of maxillary defects. Methods: 27 consecutive cases of maxillary reconstruction with free flap were reviewed. All clinical data were analyzed, including ideal selection of flap, time of reconstruction, recurrence of cancer, postoperative complications, flap design, and follow-up results. The main operative functional items, including speech, oral diet, mastication, eye globe position and function, respiration, and aesthetic results were evaluated. Results: Among the 24 patients who underwent maxillary reconstruction with the free flap, 14 patients underwent immediate reconstruction after maxillary cancer ablation, and 10 patients underwent delayed reconstruction. There occurred 1 flap loss. Recurrences of the cancer after the reconstruction happened in 2 cases. Postoperative complications were 3 cases of gravitational ptosis of the flap, 2 cases of the nasal obstruction, and 1 case of fistula formation. Out of 27 free flaps, there were 15 latissimus dorsi myocutaneous flaps, 5 radial forearm, 4 rectus abdominis myocutaneous flaps, 1 scapular flap, 2 fibula osteocutaneous flap, respectively. Flaps were designed such as 1 lobe in 9 cases, 2 lobes in 9 cases, and 3 lobes in 5 cases. Among the 14 patients who had intraoral defect or who had palatal resection surgery, 2 patients complained the inaccuracy of the pronunciation due to the ptosis of the flap. It was corrected by the reconstruction of the maxillary buttress and hung the sling to the upper direction. All of the 14 patients were able to take unrestricted diets. In 6 patients who had reconstruction of inferior orbital wall with rib bone graft, they preserved normal vision. Aesthetically, most of the patients were satisfied with the result. Conclusion: LD free flap is suggested in uni-maxilla defect as the 1st choice, and fibular osteocutaneous flap and calvarial bone graft to cover the larger defect in bi-maxilla defect.

A retrospective analysis was performed to assess the relationship between the treatment modalities and treatment results in patients with adenoid cystic carcinoma of the maxillary sinus. From Feb. 1977 to March 1994, 10 patients with the disease were treated at the Department of Radiation Oncology, Yonsei Cancer Center, Yonsei University College of Medicine. Six men and 4 women were presented with median age of 57 years. According to AJCC TNM system, all patients except one had advanced T3 and T4 disease. Only one patient had the regional metastasis to lymph node but none of them had hematogenous metastasis on initial admission. One patient(Group 1) was treated with surgery alone, 3 patients(Group 2) were treated with definitive radiotherapy and 6 patients(Group 3) were treated with combination of surgery and radiotherapy. One patient who was treated with surgery alone had experienced a locoregional recurrence 9 months later and 3 patients who were treated with radiation therapy alone had PRs(partial response) followed by the subsequent progression of the local disease. Whereas all patients who were treated with combination of surgery and radiation therapy had CRs(complete response). Among them, only one patient was recurred in the primary site, who was salvaged by reoperation and reirradiation therapy. In conclusion, combination of surgery and radiotherapy resulted in the best treatment modality for adenoid cystic carcinoma of the maxillary sinus. Improved radiotherapy technique and development of multimodality treatment are needed to improve the local control and the survival rate in patients with advanced adenoid cystic carcinoma of the maxillary sinus.

상악암은 비교적 진행되어서야 발견되는 수가 많지만 경부 임파절 전이나 원격 전이는 다른 두경부 암에 비해 흔하지 않기 때문에 종양의 국소 억제가 치료의 성패를 좌우하게 된다. 그러나, 상악동은 안와나 두개저에 접하고 있어서 다른 악성 종양처럼 충분하게 안전한 절제연을 두고 제거하는 것이 불가능한 수가 많다. 한편 대부분의 시설에서 수술과 방사선요법을 단독 또는 병행요법으로 시행하고 있는데 그 치료성적이 보고자에 따라 다양하며 비교적 좋지 못한 형편이다. 저자들은 88년 t월부터 91년 12월까지 상악암으로 진단받고 동맥내 항암제 주입요법, 방사선 치료및 수술을 포함한 집합적 치료를 시행하였던 16례(전례 편평상피암, T2 1례, T3 6례, T4 9례, 평균 연령 57.2세)에 대하여 그 결과를 후향적으로 검토하였다. Kaplan-Meier법에 의한 5년 생존률은 51.95%였으며 안구나 구개, 안면 피부등을 일부 보존할 수 있었고 기능적으로도 만족할 만하였다.

Objectives: Maxillary cancer is notorious for its poor prognosis because it is usually detected lately and the majority of patients have advanced disease. Especially when the cancer extended to infratemporal fossa or pterygopalatine fossa it is very difficult to remove all the involved structure by conventional maxillectomy. In these cases we have used radical maxillectomy through lateral approach. We tried to figure out the clinical significance of this procedure. Material and Methods: This study retrospectively analyzed 23 patients with squamous cell carcinoma of the maxillary sinus who underwent surgical treatment for cure. Among them 17 patients(group A) were treated with initial surgery and 6 patients(group B) underwent salvage surgery after radiotherpy. Radical maxillectomy was performed in 12 patients and conventional total maxillectomy in 11 patients. Results: In group A, 3 out of 9 total maxillectomy case and none of 8 radical maxillectomy case were recurred. In group B one patient died of postoperative complication and among the other 5 patients only one out of 3 radical maxillectomy was salvaged and 2 total maxillectomy cases were died of intercurrent disease. Conclusion: Wide surgical dissection of pterygopalatine fossa and infratemporal fossa may improve the survival rate in patients with posterior wall invasion of maxillary sinus.
