  • Intracranial involvement by adenoid cystic carcinoma (ACC) is very rare and there is no report of intracranial extension from the palate ACC in Korea. Intracranial involvement can occur in one of three ways: direct extension, perineural spread, and hematogenous spread. A case report of a 35-year-old woman with intracranial ACC is presented. Initially she had ACC of the right palate and was treated by surgery and postoperative radiation therapy. Three years and 10 months later, the paresthesia in the distribution of ophthalmic and maxillary branch of right trigeminal none developed without evidence of recurrence in CT scan. Ptosis and total ophthalmoplegia developed sequentially and the second operation was peformed. It was suggested that the tumor was spread perineurally along the trigeminal news into the Gasserian ganglion and then cavernous sinus and orbit. Seven years and 6 months after the first operation, direct intracranial extension into the right temporal lobe developed via sphenoid bone, sphenoid sinus and temporal bone and the third operation was done. And then lung metastasis was diagnosed. She is alive for 9 years 5 months after first operation.

  • Patients undergone partial maxillectomy experience post-operative masticatory, phonetic, and swallowing difficulties. They also encounter social and psychological challenges due to changes in their facial appearances. Thus, functional and esthetic recovery through maxillofacial prosthesis becomes significant for these patients. The objective of an appropriate obturator is to restore palate and improve phonetic and swallowing ability by separating the oral cavity, nasal cavity, maxillary sinus, and nasopharynx. In this case report, an obturator was fabricated for a patient who had partial resection from the maxillary posterior region to the pharynx due to squamous cell carcinoma. The purpose of this case study is to describe the results because the patient was successfully improved both functionally and esthetically.

  • Most patients with acquired maxillary surgical defects have difficulties such as functional impairments of mastication, speech, and deglutition as well as various degrees of facial deformity. The purpose of a prosthetic approach is to restore function and appearance with an obturator as normal as possible. This goal can be achieved when there is thoughful preoperative communication between a prosthodontist and a surgeon regarding a rehabilitation. In this case report, prosthetic rehabilitation was planned before the surgery for the patient diagnosed with squamous cell carcinoma in the right maxillary sinus with careful oral examination. Four months after maxillectomy, a definitive obturator was fabricated following the surgical and interim obturation phase. The objective of this case report is to describe the satisfactory results of the patient with improved rehabilitation of mastication, speech, deglutition, and appearance.

  • This is a report of adenoid cystic carcinoma occurred in the palate in 30-year-old patient with a complaint of exophytic mass. The authors diagnosed it as adenoid cystic carcinoma by the clinical examination, radiographic findings and histopathological findings. The obtained results are as follows: 1. In clinical examination, asymptomatic exophytic mass of palate was observed. 2. In radiographic findings, soft tissue mass infiltrated the left maxillary sinus, nasal cavity, infraorbital fossa, hard palate, pterygopalatine fossa and pterygoid plate, and enhanced soft tissue mass was also observed in CT. 3. In histopathological findings, tubular and solid patterns of glandular structures were observed and the infiltration of tumor cells into the nerve fibers was also observed. 4. Two years after radical surgery, radiation therapy and chemotherapy, the perineural spread to orbital area was observed. 5. Much longer follow-up than 5 years is needed for early diagnosis of recurrence and distant metastasis.

  • Metastatic squamous cell carcinoma was described in two female Pere David's deer reared at Everland zoo. Both deer with chronic emaciation had the mass on right maxilla(9$\times$11$\times$15cm or 20$\times$17cm) which was composed of miliary tan creamy contents and encapsulated by connective tissue. The undulating contents in the mass was a1so extended in the underlying or adjacent soft palate, maxillary and frontal sinus causing severe bone destruction. In one deer, two fistula were also noted in the right periocular area. Histologically, the neoplastic masses of both deer consist of anastomosing cords or nests of squamous epithelial cells with intercellular bridge or keratin pearl formation. The neoplastic cells invade deep into the subcutis and bony tissue. Mitotic figure was rare. Multifocal areas of necrosis and hemorrhages were also noted in the dermis. Metastasis to maxilla and ethmoid bones and/or to submandibular lymph node was noted in both cases. The diagnosis was based on the results of histopathology.

  • Introduction: Maxillary malignant tumors are primary tumors of the maxillary gingiva, sinus, and palate. The purpose of this study was to research the prognosis and treatment modalities of maxillary malignant tumors. Materials & Methods: For this study, 52 patients, who were treated after being diagnosed for maxillary malignant tumors at the department of OMFS at Yonsei University college of Dentistry from January 1997 till April 2008, were classified, then the prognoses of these patients were evaluated depending on their primary site, histopathology and treatment modalities. The results of this study showed that the most common primary site for maxillary malignant tumors was the gingiva and for histopathology, squamous cell carcinoma. Result & Conclusion: The average follow up period was 32.7 months. In determining prognosis, the most important factors were the control of local site and metastasis of cervical lymph nodes. Therefore, for a better prognosis, a tumor free margin during surgery and a periodic follow up to examine for metastasis to cervical lymph nodes and other organs are necessary.

  • Background: Most of the cancers of maxillary sinus are the squamous variety, but various histopathologic types of malignant tumor can occur in the maxillary sinus. These non-squamous cell tumors have quite different patterns of clinical behavior compared with squamous variety, such as invasive characters, route of metastasis, treatment modality, and so on. Objectives: The authors intend to establish the clinical characteristics and treatment modalities of non-squamous cell tumors of the maxillary sinus. Material and Methods: We experienced 16 cases of non-squamous cell tumors arisen from the maxillary sinus during the 10-year period from 1987 to 1996. We analyzed their clinical features, therapeutic modalities and results with review of literatures. Results: According to AJCC TNM system, 13 patients presented with $T_{1-2}$, 3 with $T_{3-}4$, Two patients were treated with surgery after radiotherapy, 3 patients with surgery after chemotherapy and radiotherapy, 4 patients with chemotherapy and radiotherpy, 5 patients with chemotherapy and radiotherapy after surgery. Conclusion: In cases of adenoid cystic carcinoma, adenocarcinoma and sarcoma, we believe that the best form of therapy is wide surgical excision. If there is microscopic evidence of disease at or close to the resection margin, postoperative radiation was used to achieve better local control. In cases of undifferentiated carcinoma, preoperative chemotherapy and radiation therapy showed improved outcomes.

  • This type of neuropathic pain(atypical odontalgia) is seen most often in middle-aged women or men after dentoalveolar operation. Atypical odontalgia probably is caused by deafferentation leading to intraneural changes in the medullary dorsal horn. Treatment of this problem is difficult, but some success has been reported in uncontrolled, open-labeled studies using high doses of tricyclic antidepressants. This is the management report of a patient case, that had a neuropathic atypical odontalgia recognized with the right maxillary lateral incisor. The patient was consulted to the Department of Pain Clinics, ENT & Neurology and diagnosed the adenoid cystic carcinoma on left cerebellum and right paranasal sinus with extension to the cavernous sinus. In spite of the osteoplastic craniotomy, neurosurgical mass removal and radiation therapy were done with chemotherapy, atypical odontalgia was continued. In addition to the consultation to Psychology, stress management and antidepressant medication were done and improved slowly.

  • Background: Lateral rhinotomy and medial maxillectomy, an en bloc resection of the medial maxillary sinus, ethmoid sinus with the lamina papyracea, medial orbital floor, and lacrimal fossa-duct, have been advocated for lateral nasal wall neoplasms as a standard approach method. Objective: This report was conducted to investigate the clinical efficacy of lateral rhinotomy and medial maxillectomy for lateral nasal wall neoplasms. Materials and Methods: We retrospectively analyzed clinical data of 31 patients who were treated at department of otolaryngology-head and neck surgery, Catholic university of Korea, school of medicine between 1990 and 1996. Results: Twenty five patients had benign lesions(80.6%). By far, the largest percentage was inverted papillomas(80%, 20/25). Of the six malignant lesions(19.4%), 33.3%(2/6) was squamous cell carcinoma and other lesions were metastatic renal cell carcinoma, adecarcinoma, transitional cell cacinoma, and hemangiopericytoma. There were a 4% recurrence for benign tumors(1/25), 5% especially for inverted papilloma(1/20), and 50% for malignant neoplasms(3/6). The overall complication rate was 9.7%. Conclusion: Despite the various approach for treatment of lateral nasal wall neoplasms including inverted papilloma, we continue to advocate a lateral rhinotomy and medial maxillectomy as the treatment of choice.

  • Prosthetic rehabilitation of an edentulous patient who has a maxillary defect is difficult to achieve for many clinicians. The maxillary defect causes leakage of air during pronunciation and compromises denture stability, support and retention by reducing denture-bearing area and breaking peripheral seal. In these patients, the sizes and shapes of defects are very important factors which attribute to prognosis of maxillary obturators. This case report shows the prosthetic rehabilitation of the patient who had maxillectomy on the right maxillary sinus because of squamous cell carcinoma. The patient had a stepwise treatment protocol which started with pre-operative dental examination and followed by surgical, interim and definitive obturation phase. In this case, an acceptable level of retention could be obtained due to well-defined static defects and the preserved premaxillae and the patient was satisfied with the result of the treatment in the aspect of function and esthetics.
