When the tumor extends into the sella turcica, removal of the posterior planum sphenoidale and tuberculum sellae may be required to gain adequate intrasellar exposure.94 After removal of tumor, any defects communicating with the sphenoid sinus must be obliterated with fat and pericranial grafts.

Involvement of the optic nerve immediately behind the optic foramen can produce bilateral visual problems. The inferior nasal fibres of the opposite optic nerve not only cross in the chiasm but also sweep forwards into the optic nerve before turning sharply to head posteriorly into the chiasm and optic tract. They can therefore be damaged by a lesion just anterior to the chiasm. A meningioma of the tuberculum sellae is the most likely lesion to be found at this site. This can produce a blind eye, an upper temporal field defect in the contralateral eye (called a junctional scotoma) and, if large, may cause loss of smell on the same side as the blind eye and eventually papilloedema in the opposite eye, the swelling in the blind eye being prevented by the compressing lesion. This constitutes the well known, but extremely rare, Foster–Kennedy syndrome.

Meningiomas and pituitary tumours are the two most prevalent benign tumours of the central nervous system (meningiomas: 35.9%, pituitary tumours: 15.5%)1 but neither are common and without a history of radiotherapy their concomitant occurrence is extremely rare.2 We describe a patient with a large sellar tumour and bitemporal hemianopsia. During surgery, two different types of tissue were recognized, which were pathologically diagnosed as an infradiafragmatic sellar pituitary non-functional adenoma with an abutting tuberculum sellae meningioma. During the sinonasal part of surgery a third tumour was identified and removed, which at pathologic examination showed a glomangiopericytoma. Surgical strategy and video are presented. In addition, a literature review of the coincidence of these tumours was conducted. Written informed consent was obtained from the patient for the publication of this case report and any accompanying images.
From above or from below? That is the question. Comparison of the supraorbital approach with the endonasal approach. A cadaveric study

The most important difference between these two approaches was observed in the anterior portion of the anterior skull base. In fact, with the supraorbital approach we moved up to reach the entire insertion of the falx, the inner portion of the frontal bone and the posterior wall of frontal sinus, which was impossible to reach through the transnasal approach for the presence of the frontal sinus that limited our view, with a margin of 1 centimeter (Figure 1(H)). Furthermore we reached the orbital face of the frontal lobe, cribriform plate, planum sphenoidale, tuberculum sellae, anterior clinoid process, sphenoid ridge, optic canal, anterior communicating arteries, carotid artery and its branches, pituitary stalk, interpeduncular cistern and oculomotor nerves.14

According to Simpson classification for patients undergoing meningioma operation, 26 patients were categorized as Simpson grade 2 (%70.2), 5 patients were categorized as Simpson grade 3 (%13.5), 4 patients were categorized as Simpson grade 4 (%10.8) and 2 patients were categorized as Simpson grade 5 (%5.4) resection. Complications occurred in four patients. One patient had died after operation for tuberculum sellae meningioma (The mortality rate for tuberculum sellae meningioma was 4.5%). Two patient developed anosmia after surgical removal. And one patient had left-sided hemiparesis after surgery.
