The meningioma constitutes 12 to 16 percent of all intracranial tumors. Generally, meningiomas arise from intracranial arachnoid villi and located intracranially. Extension of an intracranial meningioma onto the frontal and ethmoidal sinus occurs occassionally, but primary meningiomas of the frontal and ethmoidal sinus are extremely rare. The authors experienced a case of cystic, meningotheliomatous meningioma containing lamellated calcification involving of the lest frontal and ethmoidal sinus, which presented with protrusion of frontal bone and exophthalmos. In addition to our case, other types of extracranial meningioma are discussed with review of literature.

A patient with frontal sinus hypertrophy complained about an bossing in eyebrow region, increased width of the upper nasal pyramid, inferior displacement of the eyebrow and deep furrows in his forehead, etc. This case report illustrated a method of correction for frontal sinus hypertrophy. Surgery was performed via the bicoronal incision. After the anterior wall of the frontal sinus was removed, we tried a frontal bone remodeling by dividing it into three pieces, trimmming each piece at the margin and fixed with microplate. Bilateral thick bony portions around the frontal sinus were shaved with a surgical burr. At the same time, a 1cm-forehead lift and frontal muscle partial resection was performed. A satisfactory aesthetic result with a smooth and wide forehead could be obtained by employing this technique.

PURPOSE: The frontal sinuses are a pair of triangularly shaped, air-filled chambers lined by mucoperiosteum and located between the inner and outer tables of the frontal bone. Until recently, our understanding of gender variations in craniofacial anatomy has been chiefly built upon anthropometric studies, which typically employ facial surface measurements or plain film radiography. The aim of this study i to determine the sizes of the frontal sinus in both sexes in Koreans. METHODS: 95 Korean subjects who underwent maxillofacial 3-Dimensional computed tomography(CT) between January 2009 and December 2009 were enrolled. Frontal sinus dimensions and forehead measurements were taken at midline and at 10, 20, and 30mm to the left and right of midline using sagittal, coronal, and axial images. The data was analyzed for significant differences between measurements made at the selected points in the frontal sinus, for left to right variations, for gender variations, and for racial differences. RESULTS: The mean thickness of the anterior table ranged from 2.31 to 3.23mm. Mean anteroposterior depth of the frontal sinus ranged from 7.38 to 9.45mm and did not vary significantly at any distance from midline. Frontal sinus height was greatest at midline(mean=29.24mm) and progressively lessened at lateral distances. Mean total width at the level of the supraorbital ridge was 53.66mm. For all measurements, no significant left to right variation was noted. Comparing the sexes, males were found to have greater dimensions in most frontal sinus measurements, though these differences were only found to be significant at or close to midline. The male forehead was marked by more acute nasofrontal angle(133.3degrees versus 141.6degrees) and a steeper posterior forehead inclination(14.9degrees versus 7.7degrees). CONCLUSION: Using CT imaging, forehead and frontal sinus dimensions have been described. Generally, males had larger overall frontal sinus dimensions. And Korean had similar sized frontal sinus to Caucasian in height and width. But in AP distance Korean had lesser measurement. The result of this study may be helpful in the comprehension of normal size of frontal sinus in Korean.

Frontal sinus fractures, particularly anterior sinus fractures, are relatively common facial fractures. Many agree on the general principles of frontal fracture management; however, the optimal methods of reduction are controversial. The subbrow approach enables accurate reduction and internal fixation of the fractures in the anterior table of the frontal sinus by allowing direct visualization of the fracture. Given the surgical success in reduction and rigid fixation, patient satisfaction, and aesthetic benefits, the transcutaneous approach through a subbrow incision is superior to other reduction techniques used in the management of an anterior table frontal sinus fracture.

An en bloc bilateral osteotomy of the orbital roofs and frontal sinus for large or deeply situated anterior skull base tumors offers less brain retraction and a wide exposure. The authors describe en bloc bilateral osteotomy of the orbital roofs and frontal sinus, with skull base reconstruction using inner table of the patient's own frontal bone flap. The approach in this report offers the advantage of wide exposure, one-site operation and short operation time.

Malignant Meningioma is rare and its initial clinical course tends to be short but otherwise indistinguishable from that of benign meningioma. And although it has been noted that many of them have propensities for invading the dural venous sinuses, the skull, and even extracranial tissues by direct spread, there seems little tendency for these to metastases. The changes of recurrence and eventual death are high in malignant meningioma. Recently we have experienced a case of malignant meningioma involving the right frontal bone and frontal lobe with infiltration to the adjacent structures.
