    A Computed Tomography Study of the Sella Turcica in Chiari Malformation Type 2
    (Lippincott Williams and Wilkins, 2025) Yalinkiliç, A.; Beger, B.; Erdem, M.Z.; Sönmez, B.; Karaaslanli, A.; Çetin, C.Ş.; Beger, O.
    Objective: To reveal differences in morphology of the sella turcica (ST) in patients with Chiari malformation type 2 (CMT2) by comparison normal subjects. Methods: Computed tomography slices of 46 CMT2 (sex: 22 females and 24 males, and mean age: 8.80±5.87 y) and 46 controls (sex: 22 females and 24 males, and mean age: 8.48±5.13 y). Results: Patients with CMT2 had statistically similar ST size (its surface area, height, width, length, and diameter) to controls. Four configurations regarding Axelsson shape types were detected in CMT2s (normal sella: 71.70%, oblique anterior wall: 15.30%, irregularity: 6.50%, and pyramidal shape of the dorsum sellae: 6.50%) and controls (normal sella: 76.10%, oblique anterior wall: 10.90%, irregularity: 6.50%, and pyramidal shape of the dorsum sellae: 6.50%). Three configurations regarding Camp shape types were detected in CMT2s (oval: 28.30%, round: 67.40%, and flattened: 4.30%) and controls (oval: 26.10%, round: 71.70%, and flattened: 2.20%). CMT2 did not correlate with Axelsson (P=0.942) or Camp (P=0.804) shape types. Conclusion: The authors' computed tomography study displays that ST size and shape in CMT2s were similar to that of healthy subjects. © 2025 by Mutaz B. Habal, MD.

    Morphometric Properties of the Tensor Fascia Lata Muscle in Human Foetuses
    (Via Medica, 2018) Beger, O.; Koc, T.; Beger, B.; Uzmansel, D.; Kurtoglu, Z.
    Background: In neonatal and early childhood surgeries such as meningomyelocele repairs, closing deep wounds and oncological treatment, tensor fasciae lata (TFL) flaps are used. However, there are not enough data about structural properties of TFL in foetuses, which can be considered as the closest to neonates in terms of sampling. This study's main objective is to gather data about morphological structures of TFL in human foetuses to be used in newborn surgery. Materials and methods: Fifty formalin-fixed foetuses (24 male, 26 female) with gestational age ranging from 18 to 30 weeks (mean 22.94 +/- 3.23 weeks) were included in the study. TFL samples were obtained by bilateral dissection and then surface area, width and length parameters were recorded. Digital callipers were used for length and width measurements whereas surface area was calculated using digital image analysis software. Results: No statistically significant differences were found in terms of numerical value of parameters between sides and sexes (p > 0.05). Linear functions for TFL surface area, width, anterior and posterior margin lengths were calculated as y = -225.652 + 14.417 x age (weeks), y = -5.571 + 0.595 x age (weeks), y = -4.276 + 0.909 x age (weeks), and y = -4.468 + 0.779 x age (weeks), respectively. Conclusions: Linear functions for TFL surface area, width and lengths can be used in designing TFL flap dimensions in newborn surgery. In addition, using those described linear functions can also be beneficial in prediction of TFL flap dimensions in autopsy studies.
