코골이와 수면무호흡증은 대부분 상기도의 인두부위의 폐쇄에 의해 발생되므로, 이 부위의 폐쇄를 방지하기 위해 혀나 하악을 전방으로 이동시키는 다양한 구강내 장치가 코골이 및 수면무호흡증의 치료에 사용되고 있다. 본 연구는 세 종류의 코골이장치 즉, 하악전방이동장치(mandibular advancement appliance, MAA), 혀견인장치(tongue retaining appliance, TRA), 하악-혀전방이동장치(mandibular advancement-tongue retaining appliance, MATRA )가 구인두와 하인두 공간을 어떻게 변화시키는지를 비교하고자 하였다. Class I 교합을 갖고 코골이 및 수면무호흡증의 증상이 없으며 체질량지수 (BMI)가 정상인 남성 9명을 대상으로 상기 세종류의 코골이장치를 제작하였으며, 이때 MAA, MATRA의 하악전방이동량은 5mm로 TRA, MATRA의 혀전방이동량은 10-20mm로 설정하였다. 그리고, 코골이장치를 장착하지 않은 CO상태와 MAA, TRA, MATRA를 장착한 상태에서 측모두부 규격방사선사진을 촬영한 후, 구인두와 하인두 공간, 두경부 자세, 연구개와 설골의 위치와 관련된 20가지 측정항목에 대해 통계분석을 시행하였다. 분석결과 MAA, TRA, MATRA 모두 상부 구인두 공간을 유의성 있게 증가시켰으나, MATRA 만이 하부 구인두 공간을 유의성 있게 증가시켰다. 이러한 결과는 코골이와 수면무호흡증을 개선시키는데 있어 MATRA가 MAA와 TRA에 비해 효과적일 수 있음을 시사한다.

Inflammatory pseudotumor is characterized by the presence of a mass that may mimic malignancy and is composed of spindle cells mixed with variable amounts of extracellular collagen, lymphocytes, and plasma cells It is benign tumor commonly involves lung and orbit and rarely that occurs in the head and neck The cause and pathogenesis of inflammatory pseudotumor still remain controversial. Some bacterial infection or chronic irritation may have prompted some speculation that an initially reactive process can change into an overt neoplastic disease. It tends to affect children and young adults than old ages. We present a case of inflammatory pseudotumor involving the tongue base, in a 73-year-old patient with repeated oral bleeding that aggravated over a few days. Clinical examination showed angiomatous polyp like findings in oropharynx that easy bleeding tendency. CT images showed well defined soft tissue mass with focal enhancement. After surgery, tumor was finally diagnosed inflammatory pseudotumor by histopathologic examinations showed plasma cells and inflammatory cells in variable fibrotic tissues.

Neurinoma originates from any nerve covered with a Schwann cell sheath and can occur in any cranial, sympathetic, or peripheral nerve. Hypoglossal neurinomas are rare and most of them are intracranial, but they may extend extracranially. Most intracranial neurinoma arise from the sensory division of cranial nerve but a motor nerve such as hypoglossal nerve is rarely involved. Although the typical sign of hypoglossal neurinoma is ipsilateral hemiatrophy of the tongue, it is easily overlooked. For the diagnosis of hypoglossal nerve tumor, CT scanning with contrast enhancement and MRI should be included, and they are greatly aids in planning the radical removal of the tumor. We experienced a case of intracranial hypoglossal neurinoma with extracranial extension in a 43-year-old woman. The patient showed otherwise unremarkable except 4 months history of right infraauricular mass and right tongue hemiatrophy. Computed tomography and magnetic resonance imaging for local diagnosis was valuable and we could remove the mass by one stage operation via suboccipital transcervical approach.

Chondroid choristomais a rare tumor like lesion of normal tissue in an unusual location. Oral cavity chondroid choristoma is exceedingly uncommon. This lesion is commonly covered by normal oral mucosa and can develop during a whole lifetime. We experienced a case of 57-year-old man who presented as 6-months history of asymptomatic mass on the dorsal surface of the tongue. We performed surgical excision under local anesthesia, and the pathological diagnosis was chondroid choristoma. After surgery, patient was followed up without any recurrence and discomfort. Therefore, we report this case with a review of literature.

Matrix metalloproteinase(MMP) is the proteolytic enzyme of the extracellular matrix. MMPs play a role in the invasion and metastasis of malignant tumor, but it is not known whether the expression of MMPs in squamous cell carcinoma of the tongue is related to the prognostic factors of this tumor. In this study, 32 paraffin-embedded tumor specimens were examined immunohistochemically using monoclonal antibodies of MMP-2, MMP-3, MMP-10 and MMP-13. The possible relationships between the expressions of the MMPs and TNM staging, the differentiation of tumor cells, size of tumor mass and lymph node metastasis were anlaysed statistically. The results were as follows. 1. The expression of MMP-2 increased according to TNM staging (P<0.05) and lymph node metastasis (P<0.05) and the expression of MMP-2 was not affected by the differentiation of tumor cells or tumor size. 2. The expression of MMP-3 increased with increasing tumor size (P<0.05). However it was not related to TNM staging, the differentiation of tumor cells or lymph node metastasis. 3. The expression of MMP-10 was unrelated to TNM staging, differentiation of tumor cells, lymph node metastasis or tumor size. 4. The expression of MMP-13 increased as tumor size increased (P<0.05). However it was not related to TNM staging, the differentiation of tumor cells or lymph node metastasis. We concluded that the expression patterns of MMP-2, MMP-3, and MMP-13 may play a role in the diagnosis, treatment plan and prognostic evaluation of malignant tumors of the tongue.

There are very few case reports of the diagnosis and management of concurrent oral cavity and parapharyngeal space tumors. We present a case involving a 49-year-old female who presented with oral cavity squamous cell carcinoma confirmed by biopsy. Initial diagnostic workup revealed a concurrent parapharyngeal mass. Diagnostic studies and surgical therapy were tailored to account for both pathological entities. The patient was treated with a combination of surgery and adjuvant therapy. The surgical strategy was designed to address both lesions simultaneously. One year post-surgery, the patient had good response to therapy with no evidence of persistent or recurrent disease. This report discusses the outcome and treatment of a rare case of concurrent squamous cell carcinoma with a complicating parapharyngeal space tumor. It explores the diagnostic process, comprehensive workup, and the surgical management.

As public awareness of the various warning signs of malignancy increases, so does the concern evoked by the self identified finding of mass in the head and neck area. Not all the palpable masses are always significantly abnormal, but any nontender mass especially to the adult is significant enough to warrent further full investigation and follow up, the object of which should be to determine the possibility of malignancy and urgency of treatment. Approach to the diagnosis of the neck mass is so important in that it affects decision regarding further evaluation would lead to the determination of the most efficacious mode of therapy, eventually to the good prognosis. So, it should be emphasized that approach to the diagnosis of neck mass should be planned, systematic and thorough, this begins with the taking careful history following performance of complete examination of the head and neck especially to the nasopharynx, tongue base, pyriform sinus, palatine tonsil and larynx. Then a number of laboratory and radiologic studies are available, following triple endoscopy under general anesthesia and blind biopsy if needed. The most important rule to keep is that any biopsy procedures should be delayed to the last modality of effort to the diagnosis and if it should be done, under the plan of radical neck dissection.

Objectives: We report an interim result of conformal radiotherapy in a patient with early stage cancer at the base of the tongue, which developed in a previously irradiated area. Materials and Methods: A 64-year-old male patient was diagnosed with T4N0M0 supraglottic cancer. He received 72Gy of radiation therapy from 21 November 1988 to 24 February 1989. He had local failure and underwent a salvage total laryngectomy on 28 August 1989. Subsequently, he did well. In early 1999, he suffered from throat pain. He had a 2.5cm ulcerative mass at the base of his tongue, in the area that had been irradiated previously. Biopsy showed squamous cell carcinoma. After workup, he was diagnosed with base of tongue cancer with T2N0M0. Surgery was not feasible because the morbidity was not acceptable. Since it was difficult to re-irradiate the area with a curable dose using conventional 2D radiation therapy with an acceptable morbidity, we decided to try conformal radiotherapy. We used 7 static beam ports with field sizes from $7x6.4\;to\;8x8cm^2$, using 6 and 10MV photons. The fractionation regimen was 1.8Gy, 5 times per week. He received 64.8Gy in 36 fractions from 9 April 1999 to 1 June 1999. Results: In the 21 months since radiotherapy, the patient has not experienced any acute or chronic complications, such as xerostomia. He experienced relief of pain shortly after the start of radiotherapy, showed a complete response, and is still doing well. Conclusion: Conformal radiotherapy can be used to treat cancer that develops within a previously irradiated field, with curative intent.
