Precise knowledge of the infraorbital canal corpus types and relationship with the morphometry allow surgeons to choose an appropriate surgical approach to avoid iatrogenic infraorbital nerve injury.

Preoperative radiologic analysis of the vidian canal and the surrounding structures will allow surgeons to choose an appropriate endoscopic approach to ensure predictable postoperative outcomes.

Numerous neurological lesions and tumors of the paranasal sinuses and oral cavity may spread into the middle and posterior cranial fossae through the anatomical apertures. For the appropriate management of these pathologies, many extensive surgical approaches with a comprehensive overview of the anatomical landmarks are required from the maxillofacial surgery's point of view. The surgical significance lies in the fact that iatrogenic injury to the petrous segment of the temporal bone including the carotid artery, sigmoid sinus, and internal jugular vein, can lead to surgical morbidity and postoperative pseudoaneurysm, vasospasm, or carotidcavernous fistula. To simplify understanding complex anatomy of the temporal bone, we aimed to review the surgical anatomy of the temporal bone focusing on the associations between the surface landmarks and inner structures. Also, breaking down an intricate bony structure into smaller parts by compartmental approach could ease a deep concentration and navigation. To identify the anatomic architecture of the temporal bone by using reference points, lines and compartments can be used to supplement anatomy knowledge of maxillofacial surgeons and may improve confidence by surgical trainees. Especially, this systematic method may provide an easier way to teach and learn surgical spatial structure of the petrous pyramid in clinical applications.

AIM: To provide detailed information about anterior skull base anatomy. MATERIAL and METHODS:In terms of gender and laterality, the drainage pathways and anatomical variations of the frontal sinus, crista galli and nasal septum in 402 patients were evaluated via computed tomography scans. RESULTS:The pneumatization patterns of the frontal sinus were as follows: absent, 3.7%; unilateral, 8%; bilateral, 75.1% and triple, 13.2%. The pneumatized crista galli was identified in 120 (29.8%) patients, and its drainage pathway was observed in 54.1% of patients. The sinus septi nasi was identified in 92 (22.8%) and its drainage pathway was observed in 16.3%. The prevalences of the position types of crista galli regarding the cribriform plate were as follows; type I, 18.3%; type II, 64.9%; type III, 16.8%. CONCLUSION:Despite meticulous knowledge of anatomy, preoperative radiologic evaluation creates the base for successful treatment of anterior skull base pathologies with safer and effective surgery.
