“…2). Lang used three terms to describe it [4]: ± Laterally near the frontal squama a deepening can be found, the so-called lateral endofrontal fovea. ± The highest point from the orbitomeatal line, called the endofrontal eminence, is between the lateral and middle third of the orbital roof.…”

Continuous improvement of surgical techniques is needed in skull base surgery in order to decrease intraoperative complications during various operations. However, the basis of minimizing damage in the operative field is a comprehensive knowledge of microsurgical anatomy. This article provides a detailed description of the cribriform plate and adjacent areas, based on investigations of over one thousand dried skulls and 225 computerized tomography scans of the anterior skull base. The main anatomic structures and the different types of the cribriform plate are demonstrated on color photographs and identified on CT scans as well. The variations important in anterior skull base approaches are also discussed and compared with the data found in the literature. The surface anatomy and development of the cribriform plate is described.

“…The existence of bony defects and dehiscences in the roof of ethmoidal cells is still dicussed [1][2][3][4][5][6]. These cells are of special interest in cases in whom the roof is incorpo rated into the bottom of the anterior cranial fossa.…”

During the period from 9 to 35 years of age, the ethmoidal cells form completely or partly the bottom of the anterior cranial fossa on both sides of the cribriform plate. These cells, not covered by the frontal bone, form a thin bony wall covered by the dura mater. This roof may show different shapes. In our material, consisting of 32 specimens from human skulls, the following variations were found: (1) openings with a smooth margin; (2) rarefactions; (3) openings with an irregular margin, and (4) cells with a thin wall. The openings with a smooth margin (5 specimens) had dimensions of 2–10 mm. They occurred as single or multiple formations on one or both sides of the ethmoidal roof. Rarefactions and openings with an irregular margin were found in seven specimens. Openings with an irregular margin could be an artefact due to destruction or maceration. In the openings with a smooth margin, a close contact between nasal mucous membrane and dura has to be expected. This fact may play an important role in inflammation of the ethmoidal labyrinth as well as in surgical interventions. A thin wall of the roof of ethmoidal cells and rarefactions may also present a danger during surgery.

Transnasale Chirurgie der Orbita

The endonasal surgery has a branch in the transnasal orbital surgery. For this transnasal approach the anterior skull base, the medial and infero-medial orbita, the orbital apex with the optical nerve and the sphenoid sinus are within reach. In all primary and secondary malignant lesions with extension into the orbita, the transnasal biopsy is of importance for diagnosis, particularly in metastasis to the orbit and pseudo-tumors. Benign lesions like mucoceles and osteomas are accessible and fully removable. Good results have been obtained in endonasal orbital decompression and inhomogeneous space occupying intraorbital lesions like bleedings. Among the orbital traumatism, with restrictions fractures of the medial orbital wall, medial orbital floor and foreign bodies could be operated. The transnasal approach is not indicated in all diseases, which are situated mostly intraconally, supraorbitally and lateral of the bulbus as well as in tumors with intracranial extension. In summary, the transnasal orbital approach has its place as helpful addition to the transfacial and transcranial techniques and can even replace them in certain selected indications.
