“…The intrapetrous portion of the internal carotid artery has gained a growing interest in surgery, not only because it may be involved in different pathologies [5][6][7][8] , but also because it may be accidentally damaged during surgical procedures of the skull base 9 ; in addition, it is often the target of pioneering bypass procedures used to handle vascular lesions and preliminary to the removal neoplasms infiltrating the petrous portion of the temporal bone 10 . Several authors have widely described the strict relationships with surrounding structures including the cochlea, the internal auditory canal and the bony labyrinth 10,15,16 , whereas very few studies have considered the metrical assessment of IPCA so far 6 .…”

“…The petrous portion of ICA represents the most obscure and the least detailed, as it is not easily accessible to anatomical dissection 3,4 , although it is of crucial importance in clinics and surgery. In fact, the intrapetrous carotid artery (IPCA) may be invaded by tumors originating in the jugular foramen area such as schwannoma and chemodectoma, as well as chordoma, meningioma, neuroma, cholesteatoma and cholesterol granuloma 5,6 .…”

“…Finally, surgical exposure of the horizontal segment of IPCA is important for bypass procedures including cervical-to-petrous and the petrous-to-supraclinoid ICA bypass 10 , preliminary to the removal of tumors invading the petrous portion of ICA. Therefore, the exact metrical and morphological knowledge of IPCA may prevent its involuntary damage and is basilar for a good surgical exposure of structures of interest 5 .…”

The intrapetrous portion of internal carotid artery (IPCA) is one of the most unexplored anatomical regions, and its three-dimensional reconstruction in living subjects is still missing. The present study aims at describing IPCA on 3D models extracted from head CT-scans.The intrapetrous carotid artery was manually segmented on head CT-scans of 100 healthy patients free from vascular and neurological pathologies (50 males and 50 females aged between 18 and 91 years). Angles of the posterior and anterior genu, diameter and length of the horizontal portion, and volume of the entire canal were calculated through VAM® software. Statistically significant differences according to sex and side were assessed through two-way ANOVA test (p<0.05). Correlation of each measurement with age was calculated as well.On average the angles of the posterior and anterior genu were 120.1±10.4° and 118.0±10.0° in males, 119.5±9.2° and 117.6±10.3° in females, respectively, without statistically significant differences according to sex or side (p>0.05). Average length and diameter of the horizontal part were respectively 25.5±2.9 mm and 5.8±0.8 mm in males, 24.0±2.3 mm and 5.3±0.8 mm in females. The volume of IPCA was 0.941±0.215 cm 3 in males, and 0.752±0.159 cm 3 in females. Length and diameter of horizontal portion, and volume of IPCA showed statistically significant differences according to sex (p<0.05). No correlation with age was found.This study first provided data concerning not only linear and angular measurements, but also volumes of IPCA, useful in planning surgical interventions of the cranial base.

“…The lesions at the inferior clivus pose a surgical challenge with high morbidity and mortalityto neurosurgeons because ofthe critical neurovascular structures surrounding the lesion [1][2][3][4].Many studies have described the far-lateral approach which exposed theinferior clivus superior to the anterior edge of foramen magnum [5][6][7][8]. The concern of neurovascular protection and skull base reconstruction promotes the development of surgical anatomy for the far-lateral approach [9][10][11].…”

Objective The three-dimensional (3D) visualization model has ability to quantify the surgical anatomy of far-lateral approach. This study was designed to disclose the relationship between surgical space and exposed tissues in the far-lateral approach by the volumetric analysis of 3D model. Methods The 3D skull base modelswere constructed using MRI and CT data of 15 patients (30 sides) with trigeminal neuralgia. Surgical corridorsof the far-lateral approach was simulated by triangular pyramids to represent two surgical spaces exposing bony and neurovascular tissues. Volumetric comparison of surgical anatomy was performed using pair t test. Results The morphometric results were almost the same in the two surgical spaces except the vagus nerve (CN X) exposed only in one corridor. Whereas, the volumetric comparison represented the statistical significant differences of surgical space, and bony and neurovascular tissues involved in the two corridors (P༜0.001). The differences of bony and neurovascular tissuesfailed to equal the difference of surgical space. Conclusions For far-laterl approach, the increase of exposure for the bony and neurovascular tissues is not necessarilymatched with the increase of surgical space. The volumetric comparative analysis is helpful to provide more detailed anatomical information in the surgical design.
