  • Congenital or traumatic loss on the oral and maxillary area or the loss of jaws due to the surgical excision of a tumor causes functional problems, such as masticatory and swallowing disorders, phonetic problems and psychological disorders in patients. In most cases, a prosthetic restoration is needed to resolve these problems and restore the damaged tissue and function. When loss occurs on the maxilla, foods and liquids leak into the nasal cavity, and a nasal sound can be heard due to air leakage into the removed area. In these cases, the palatal obturator can be used to improve the esthetic and functional aspects because it restores the removed area of the maxilla and closes the opened route between the oral cavity and maxillary sinus or nasal cavity. In this case report, a palatal obturator was applied to patients who had a hemimaxillectomy due to the occurrence of squamous cell carcinoma on the right maxillary area. Therefore, fundamental functions, such as phonetic and swallowing functions were restored, and the esthetic aspects of the facial profile were improved.

  • Biological behavior and treatment results of 33 patients with Adenoid Cystic Carcinoma (ACC) in the Head and Neck at Yonsei Cancer Confer for 10 years between 1971 and 1980 were retrospectively analysed. Most common, primary site was minor salivary glands such as maxillary sinus, nasal cavity and base of tongue. The typical biological behavior of these tumors was very slowly in growth with long time of duration(mean 19 months) from 1 month to 10 years and more frequent of nerve invasion but rare invasion of neck nodes. Local control and failure pattern in the results of treatment, 16 of 17 patients with irradiation alone were seen complete or partial response but 5 cases of locoregional recurrence, 2 cases of failure of neck node and 4 cases of distant metastasis as lung and brain. On the other hand, among 10 cases of surgery and postoperative irradiation, 2 cases of locoregional failure and 3 cases of distant metastasis as lung and bone. 2 of 4 cases with surgery alone were recurred within primary site. Actuarial overall NED survival at 3 ana 10 years were $52.6\%$ and $42.8\%$, respectively. Survival rate of 10 Patients with surgery and Postoperative irradiation was more high than 17 Patients of radiation alone. Therefore, we have known that surgery with postoperative adjunctive irradiation is most effective treatment modality of adenoid cystic carcinoma in the head and neck. Primary site, treatment modality and with or without nerve ana bone invasion have influenced on prognosis.

  • When a high energy photon beam is used to treat lesions located in the upper respiratory air passages or in maxillary sinus, the beams often must traverse an air cavity before it reaches the lesion. Because of this traversal of air, it is not clear that the surface layers of the lesion forming the air-tumor tissue interface will be in a state of near electronic equilibrium; if they are not, underdosing of these layers could result. Although dose corrections at large distances beyond an air cavity are accountable by attenuation differences, perturbations at air-tissue interfaces are complex to measure or calculate. This problem has been investigated for 4MV and 10MV X-ray beams which are becoming widely available for radiotherapy with linear accelerator. Markus chamber was used for measurement with variouse air cavity geometries in X-ray beams. Underdosing effects occur at both the distal and proximal air cavity interface. The magnitude depended on geometry, energy, field sizes and distance from the air-tissue interfaces. As the cavity thickness increased, the central axis dose at the distal interface decreased. Increasing field size remedied the underdosing, as did the introduction of lateral walls. Fellowing a $20{\times}2{\times}2\;cm^3$\;air\;cavity,\;4{\times}4\;cm\;field\;there\;was\;an\;11.5\%\;and\;13\%\;underdose\;at\;the\;distal\;interface,\;while\;a\;20{\times}20{\times}2\;cm^3\;air\;cavity\;yielded\;a\;24\%\;and\;29\%$ loss for the 4MV and 10MV beams, respectively. The losses were slightly larger for the 10MV beams. The measurements reported here can be used to guide the development of new calculation models under non-equilibrium conditions. This situation is of clinical concern when lesions such as larynx and maxillary carcinoma beyond air cavities are irradiated.

  • 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.

  • Inverted papilloma arising from mucous membrane of the nasal cavity and paranasal sinuses is very rare benign neoplasm. Ward first described nasal papilloma in 1854, but its infrequent occurrence has delayed accurate understanding. This tumor was histologically benign neoplasm and clinically malignant, because it is locally invasive with extensive bone erosion at times and it shows a high incidence of local recurrence, and change of squamous cell carinoma was sometimes found. Recently, the authors have experienced a case of inverted pailloma with focal squamous cell carcinoma change which occupied the right side of the nsal cavity and maxillary sinus in a 48-year-old male. The tumor mass was removed surgically through intranasal and Caldwell-Luc's approach, and then was treated with systemic administration of Bleomycin, local spray of 5-FU and radiotherapy ($Co^{60}$). We report our case with review of current literatures.

  • Forty eight patients with adenoid cystic carcinoma (ACC) in the head and neck treated between 1979 and 1990 were reviewed according to treatment modalities and clinical courses. The common site of origin was minor salivary gland ($69\%$), mostly hard palate and maxillary sinus. 11 patients received radiation therapy (RT) alone and 37 patients received combined surgery and radiation therapy. The follow-up period of the survivors ranged from 4 to 118 months (median 49.5 months). The 5 year local control rate was $69.3\%$, $67.3\%$ and 83.9$\%$ in RT alone, conservative operation (OP)+RT and radical OP+RT group, respectively (p>0.05). The control of local disease was best achieved with radical OP+RT. In postoperative RT, high dose ($\ge$60 Gy) and generous field size($\ge$64 cm$^2$) yielded a better local control rate. Actuarial overall survival rate was $79.0\%$, at 5 years and $19.2\%$ at 10 years. Distant metastases (DM) developed in $40\%$ of patients, mostly in the lung. Disease-free (NED) survival rate was $45.8\%$ at 5 years and significant differences did not exist according to primary sites and treatment options. Survival rate after the onset of DM was $19.5\%$ at 5 years. Occurrence of DM tends to lower survival significantly. In an effort to find the role of RT in the treatment of ACC, our data suggest that a well-planned postoperative RT employing a high dose and generous field size can produce high local control rate and remaining urgent problem of distant metastasis demands more effective chemotherapy for the purpose of improving survival of ACC patients.

  • [ $\underline{Purpose}$ ]: This study was to evaluate the survival and pattern of failure after radiation therapy of sino-nasal cancer using partial attenuation filer and wedged beams and to help radiotherapy planning of sino-nasal cancer. $\underline{Materials\;and\;Methods}$: Between February 1992 and March 2003, 17 patients with sino-nasal cancers underwent radiation therapy using partial attenuation filter at Dongsan Medical Center, Keimyung university. There were 9 male and 8 female patients. Patients' age ranged from 40 to 75 years (median 59 years). There were 10 patients of maxillary sinus cancer, 7 patiens of nasal cancer. The histologic type was squamous cell carcinoma in 11, adenoid cystic carcinoma in 4 and olfactory neuroblastoma in 2. The distribution of clinical stage by the AJCC system was 3 for stage II, 7 for III and 6 for IV. The five patients were treated with radiation alone and 12 patients were treated with surgery and postoperative radiation therapy. The range of total radiation dose delivered to the primary tumor was from 44 to 76 Gy (median 60 Gy). The follow-up period ranged from 3 to 173 months with median of 78 months. $\underline{Results}$: The overall 2 year survival rate and disease free survival rate was 76.4%. The 5 year and 10 year survival rate were 76.4% and 45.6% and the 5 year and 10 year disease free survival rate was 70.6%. The 5 year disease free survival rate by treatment modality was 91.6% for postoperative radiation group and 20% for radiation alone group, statistical significance was found by treatment modality (p=0.006). There were no differences in survival by pathology and stage. There were local failure in 5 patients (29%) but no distant failure and no severe complication required surgical intervention. $\underline{Conclusion}$: Radiation therapy of sino-nasal cancer using partial attenuation filter was safe and effective. Combined modality with conservative surgery and radiation therapy was more advisable to achieve loco-regional control in sino-nasal cancer. Also we considered high precision radiation therapy with dose escalation and development of multi-modality treatment to improve local control and survival rate in advanced sino-nasal cancer.
