“…Introduced by Retzius (1840) and modified by Morrison (1973) classification of the shape of the skull subdivided all individuals into three phenotypical groups with wide (brachycephalic), narrow (dolichocephalic), or normal (mesocephalic) shapes of the skull.

“…To evaluate the shape of the skull, the laterolateral and anteroposterior diameters of the skull were measured on both wet and radiologic specimens of the skull and axial MR images, as previously described. 16,17 The cranial index (CI) was calculated as a percentage ratio of the laterolateral diameter of the skull to the anteroposterior diameter. All specimens were subdivided into 3 groups according to CI value: dolichocephalic (CI<74.9), mesocephalic (CI=75-79.9), and brachycephalic (CI>80).…”

Introduction: The wide range of anatomical variability of the structures of the middle cranial fossa and the lack of reliable surgical landmarks contribute to a high level of complications in the surgical treatment of vestibular schwannomas. We hypothesized that the cranial phenotype influences the shape of the middle cranial fossa, the orientation of the pyramid of the temporal bone, and the relative topography of the internal acoustic canal. Materials and Methods: The skull base structures were studied on 54 embalmed cadavers and 60 MR images of the head and neck by photo modeling, dissection, and 3D analysis techniques. By the value of the cranial index, all specimens were subdivided into dolichocephalic, mesocephalic, and brachycephalic groups for comparison of variables. Results: The length of the superior border of the temporal pyramid, the apex to squama distance, and the width of the middle cranial fossa all peaked in the brachycephalic group. The value of the angle between the superior border of the pyramid and the axis of the acoustic canal varied from 33 to 58 º; it peaked in the dolichocephalic group and showed its smaller value in the brachycephalic one. The pyramid to squama angle had reversed distribution and dominated in the brachycephalic group. Conclusions: The cranial phenotype influences the shape of the middle cranial fossa, temporal pyramid, and internal acoustic canal. Presented in this paper data help specialists operating on the vestibular schwannoma to localize the internal acoustic canal based on the individual shape of a skull.

“…Referring to a previous study, 20 we utilized Mimics 25.0 (Materialise HQ, Technologielaan 15, 3001 Leuven, Belgium) to measure ICV above the foramen magnum. Anterior cranial height (ACH), anterior cranial base length (ACBL), and cranial height–length index 21,22 were measured preoperatively and postoperatively in feasible cases amongst patients with bilateral coronal synostosis. Any surgical complications such as dural tears and injury of venous anomalies (dilated emissary vein, fetal dural sinus) that may occur were also investigated.…”

Objective: Endoscopic suturectomy is a widely practiced surgical option for infants with craniosynostosis. But the efficacy and safety of the procedure remain unclear in syndromic patients. This study aims to evaluate the efficacy and safety of endoscopic suturectomy for patients with syndromic craniosynostosis. Methods: From January 2013 to December 2020, 242 patients underwent endoscopic suturectomy at our institution. The surgical outcome was determined to be favorable or unfavorable based upon the necessity of an additional cranial surgery upon the last follow-up. First, we analyzed the outcomes of 26 syndromic craniosynostosis patients who have followed up for over a year. Second, we compared the outcomes between the syndromic (N=12) and nonsyndromic (N=11) patients with bilateral coronal synostosis who have followed up for over a year. Results: Twenty-three out of 26 syndromic craniosynostosis patients (88%) showed favorable outcomes without significant complications. In the analysis for bilateral coronal synostosis patients, 11 of 12 syndromic patients (92%) presented favorable outcomes, and all nonsyndromic patients showed favorable outcomes. No significant differences were observed in various anthropometric indices (cranial index, intracranial volume, anterior cranial height, anterior cranial base length, and cranial height–length index) and surgical outcomes between syndromic and nonsyndromic groups. Conclusions: Endoscopic suturectomy has the potential to be a surgical option for syndromic craniosynostosis. Even for patients with unfavorable outcomes, endoscopic suturectomy could serve as a bridge treatment for infants to counter cranial deformation before additional extensive surgery.

Phenotypical variability of the sigmoid sinus in translabyrinthine and retrosigmoid surgeries

Introduction We hypothesized that the cranial phenotype influences the shape of the posterior cranial fossa and the relative position of the sigmoid sinus. Materials and methods The topography of the sigmoid sinus was studied on 26 magnetic resonance venograms and 35 embalmed cadavers by morphometric analysis, dissection, and photo modeling techniques. Results The data show that the transverse diameter of the posterior cranial fossa correlates positively with the laterolateral diameter of the skull. The majority of cases with the low-anterior position of the sigmoid sinus were recorded in the brachycephalic group (82%), while the high-posterior localization of the sigmoid sinus was typical for the dolichocephalic patients (63%). The results of the ANOVA test confirm the significance of differences. Conclusions The shape of the skull reflects the morphology of the posterior cranial fossa and influences the topographic characteristics of the sigmoid sinus that must be considered in the selection of surgical approach to the inner ear and pontocerebellar angle.
