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.

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.

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.

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.

Primary intraosseous carcinoma(PIOC) is defined as a squamous cell carcinoma arising within the jaw, having no initial connection with the oral mucosa. The squamous cell carcinoma within the bone can be presumably developed from residues of the odontogenic epithelium, therefore, it is seen in the jaw only. Metastatic carcinoma from another primary site should be excluded in the diagnosis of Primary Intraosseous Carcinoma. This is a case of 62-year-old man, who initially diagnosed as odontogenic cyst on maxilla, but its pathologic examination was diagnosed as squamous cell carcinoma with odontogenic cyst. We treated this patient with partial maxillectomy, modified radical neck dissection(mRND), and postoperative radiation therapy.

목적 :상악동암에서 수술 전 방사선 치료를 시행함으로써 안면 보존의 가능성이 어느 정도 되는지를 알아보고자 하였다. 대상 및 방법 : 1986년 6월부터 1990년 9월까지 상악동암으로 방사선치료를 받은 42례의 환자를 대상으로 후향적 분석을 시행하였다. 환자의 연령은 24세에서 75세로 중간값은 56세였으며, 남자 27예, 여자 15예였다. 병기별 분포는 T2 2예, T3 19예, T4 21예로 진단 당시 대부분 진행된 상태였다. 조직학적으로는 편평 상피암 38예, 미분화 세포암 1예, 이행 상피암 1예, 선양 낭종암 2예였다. 모든 환자에 대해 동측 부비동을 포함하는 쌍쐐기빔 방법의 방사선치료를 시행하였다. 방사선 치료선량은 50.4-70.2 Gy로 중간값은 70.2 Gy였다. 11례의 환자에 대해 방사선치료와 유도 화학요법을 병행하였다. 화학요법은 5-fluorouracil과 cisplatin으로 2회 시행하였다. 대상 환자의 추적기간은 3개월에서 92개월로 중간값은 16개월이었다. 방사선치료 후 6 내지 8개월 경과 후 전산화단층촬영을 실시하여 병소의 반응을 평가하였다. 완전관해가 된 경우는 계속 추적검진만 하였으며 병변이 의심되는 경우는 콜드웰-뤼크 수술을 시행하여 확인하였다. 병변이 확인된 경우는 상악동전절제술을 시행하였다. 결과 : 방사선 및 화학요법 시행 후 9예 (21.4$\%$)에서 완전관해를 보였고 33예 (88.6$\%$)에서 잔여병변이 확인되었다. 완전관해를 보인 9예의 환자 중 7예가 국소제어되었으며 2예에서 국소재발하였다. 잔여병변이 있는 33예의 환자 중 10예에서 근치적 수술이 가능하였고 그 중 2예에서 국소제어가 되었다. 전체 환자의 5년 생존율은 23.1$\%$였고 5년 무병생존율은 16.7$\%$였다. 방사선치료에 대한 반응 (P<0.05) 만이 생존율에 영향을 미치는 유의한 인자였다. 결론 : 방사선치료에 대한 반응만이 생존율에 영향을 미치는 유의한 인자였다. 전체적으로 7예(16.7$\%$) 에서 수술 전 방사선치료로 안면보존이 가능하였다.

Soft tissue sarcoma of the head and neck is not frequent neoplasm, accounting for less than 1% of all malignant neoplasm in the region. The histological varieties include osteogenic sarcoma, malignant fibrous histiocytoma, rhabdomyosarcoma, fibrosarcoma, tenosynovial sarcoma, angiosarcoma and chondrosarcoma. Rhabdomyosarcomas of the head and neck usually occur in children under the age of 10 years (over 70%) and rarely develop in adults over the age of 20 years. The prevalent sites of involvement include the orbit, nasal cavity, external ear, paranasal sinus and soft tissue of mouth and the primary location of tumor is considered to be one of the important prognostic factors. Before the 1960s, when surgical resection was the only method of treatment, the 5-year survival rate was less than 20%, but recently it has been greatly improved by the multimodality treatment, combining surgery with chemotherapy and radiation therapy. Here we treated a rhabdomyosarcoma woman with three cycles of high dose chemotherapy followed by radiation therapy. After the, completion of preoperative treatments, successful result of more than partial response was achieved. Three months later total maxillectomy and radical neck dissection was performed. There was no evidence of tumor infiltration in the resected tumor and regional lymphnodes but metastasized tumor cells in cervical lymphnodes were detected. Tumor cell infiltration was also found on the bone marrow biopsy to evaluate the pancytopenia which occurred during postoperative recovery. Two months later she died of secondary bone marrow failure. We think that this multimodality treatment combining pre-operative chemotherapy, radiotherapy and surgery might play an important role in curative resection and eyeball preservation in patients with rhabdomyosarcoma involving the eyeball.
