부비동염은 흔하고 일반적으로 소아에서는 양성질환인 경우가 많다. 경험적으로 사용하고 있는 항생제로 인해 소아의 부비동염의 두 개강 내 합병증은 드물지만, 발생할 경우 생명에 위협적일 수 있다. 두 개강 내 합병증은 정맥동 혈전, 안와 합병증, 뇌수막염, 뇌수막하 농양 등이 있다. 이러한 합병증은 소아에서 심각한 예후를 보일 수 있다. 따라서 뇌수막하 농양을 초기에 정확하게 진단하여 치료를 시작하는 것이 중요하다. 저자들은, 급성 부비동염 치료 중이던 15세 남아가 3일간의 발열, 두통을 동반한 편마비 증상으로 내원하여 뇌 전산화 단층촬영에서 뇌수막하 농양으로 진단되어 항생제 투여 및 신경학적 수술로 치료된 증례를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

12세의 중성화 수술을 한 수컷 미니어쳐 슈나우져종견이 급성 경련 증상으로 내원하였다. 컴퓨터단층촬영에서 좌측 비강 내 종괴와 사상판의 용해가 관찰되었다. 조영 후 자기공명영상 사진에서 좌측 전엽과 전두동에 고신호 감도의 종괴가 확인되었다. 비강 종양에 의해 이차적으로 발생한 뇌종양으로 가진단되었으며 조직검사상에서 비강샘암종이 뇌에 전이된 소견이 관찰되어 확진되었다. 개에서 발생한 비강샘암종이 침습되어 이차적으로 두개 내 종양이 발생한 증례로써 이차성 뇌종양의 이해 증진에 기여할 수 있는 자료를 제공할 수 있을 것으로 기대된다.

The lateral rhinotomy signifies only an incision and not on operation and a lateral rhinotomy incision with osteotomy of the nasal bones provides access to the entire nasal cavity and maxillary, ethmoid, and sphenoid sinuses as well as the frontal sinus if the floor is removed, permitting removal of benign lesions at these sites and en bloc resection of the ethmoid labyrinth and the party wall between the nasal cavity and antrum with infiltrating tumors. The authors treated a tumor patient and a midfacial bone fracture patient via lateral rhinotomy approach and had a good result. So we report the cases with literature review.

Pneumocephalus is exceedingly rare in the absence of trauma or recent surgery. It is most commonly seen after severe head injury, with disruption of the dura and subsequent cerebrospinal fluid leakage. Intracranial air has also been reported as a complication of shunting. This may be secondary to intermittent shunt failure or a persistent communication between the extracranial and intracranial space that permits the entrance of air. In the present case, air appeared to enter the ventricular system through the fistula that connected the frontal sinus. This air replaced the CSF being drained into the peritoneal cavity by the shunt. The decrease of intracranial pressure after a shunt might play a role in causing pneumocephalus. We report a case of tension pneumocephalus after shunting for hydrocephalus as a life-threatning complication.

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.

Typical transcranial approaches are insufficient for adequate visualization and resection of skull base tumors. Different approaches with multiple modifications have been attempted. Here, we describe a new approach for a lesion that is central and hard to treat by conventional craniotomy and successful reconstruction with calvarial bone graft and titanium mesh plate. A 69-year-old female patient presented with recurrent meningioma. The tumor had invaded the frontal lobe, right supraorbital rim, and ethmoidal bone. We performed a modified anterior craniofacial approach that fully exposed the tumor and invaded bone. In consideration of the patient's age and cosmetic result, the tumor and invaded bone was resected and the defect area was reconstructed with titanium mesh and calvarial bone graft. At 6 months postoperative the patient had no complications and was satisfied with the esthetic result. We report this case to demonstrate the successful approach and reconstruction using this technique.

Objective : To evaluate objectively the sites of injury in patients with posttraumatic olfactory deficits and to suggest the diagnostic procedure for evaluation of posttraumatic anosmia. Methods : Ten patients with posttraumatic olfactory dysfunction were examined by means of olfactory testing, sinoscopy, contrast filled paranasal sinus computed tomography(contrast filled PNS CT) and magnetic resonance imaging(MRI). Five normal persons without olfactory dysfunction were also evauluated. The aerodynamic patency of olfactory cleft was examined by contrast filled PNS CT. The olfactory system(oflactory bulbs, olfactory tracts, inferior frontal region, hippocampi, or temporal lobes) was investigated in detail with MRI. The difference in the size of the olfactory bulb between normal volunteers and anosmic patients was evaluated by Student's t test. Results : Contrast filled dynamic CT scan was useful method for the evaluation of dynamic patency of the olfactory cleft. Paranasal CT scan of the all anosmic patients showed dynamic reflux of contrast media in olfactory cleft on valsalva maneuver. For the largest cross-sectional area and great height, the difference in olfactory bulb size between normal volunteers and patients was statistically significant(p<0.001) in MRI study. Conclusion : Posttraumatic anosmia was completely evaluated by olfactory testing, sinoscopy, and contrast filled CT scan for differentiation between conductive type and neurogenic type. Neurogenic anosmia was confirmed by perfect localization with MRI study.

성공적인 종이수술을 위하여 안전하고 효과적인 접착제가 필요하며, 합성 접착제의 독성작용 때문에 인체에서 추출한 접착제를 사용하게 되었다. Fibrin 접착제가 저장 혈액에서 체취되면 감염성 질환의 전염 위험성이 있지만 자가 fibrin 접착제를 사용하면 전염위험성이 없다. 저자들은 ammonium sulfate fibrin 접착제와 상품화된 fibrin 접착제의 접착력을 비교한 결과 ammonium sulfate fibrin 접착제의 접착력이 상품화된 fibrin 접착제의 반 정도의 접착력을 가지지만 그 정도의 접착력이면 고막재생술, 안면신경 봉합술, 이소골 재건술, 외이도 후벽재건술, 뼈가루를 이용한 전두동 및 유양동폐쇄술 등 이비인후과 수술에 사용하기엔 충분한 접착력이다.

The clear cell meningioma[CCM] is a rare and recently described as a histologic variant of meningioma. It has been identified and included in new World Health Organization[WHO] classification of the Central Nervous System[CNS] tumors recently. The CCMs are histologically characterized by sheets of spindled to polygonal cells with clear cytoplasm, which is the expression of high glycogen concentration. The CCMs occur in younger patients and usually are located in the spinal canal and posterior fossa. The most interesting aspect of CCM is the high recurrence rate and aggressiveness. Poor outcome has been shown in intracranial and spinal tumor location, but the indicators that predict outcome have not been established. Until now 22 intracranial CCM cases had been reported in English literature and 3 cases in Korean. The authors report two cases of CCM located at cerebral convexity and one at cavernous sinus those were totally removed [Simpson Grade $I{\sim}II$] by subfrontal, frontal and orbitocranial approaches. The clinical, radiological, histopathological, and neurosurgical features of these cases are discussed with the relevant literatures.
