Morphometric Features of the Latissimus Dorsi Muscle in Fetal Cadavers With Meningomyelocele for Prenatal Surgery
(Lippincott Williams & Wilkins, 2019) Beger, Orhan; Beger, Burhan; Dinc, Ugur; Hamzaoglu, Vural; Erdemoglu, Ece; Ozalp, Hakan
Purpose: Latissimus dorsi (LD) flaps are frequently used in the prenatal meningomyelocele (MMC) repairs; on that basis, this study aims to reveal the morphometric features of LD, thoracodorsal artery (TDA) and nerve (TDN) in fetal cadavers with MMC defects, with an anatomical perspective. Methods: The study was conducted on 7 formalin-fixed human fetal cadavers (4 males and 3 females) with MMC defects, aged from 18 to 27 weeks of gestation. The size of LD, TDA, and TDN including their area, length, and width were measured by a digital caliper and digital image analysis software. Our direct measurements were compared with the corresponding estimations of a previous study in the literature which provides regression formulae based on gestational age. Results: The fetal cadavers with MMC had bilateral LD. No significant differences were found in the numerical data of anatomical structures between the sides or the sexes. LD size (ie, area, length and width) was approximately 3% to 10% smaller in the fetuses with MMC defects than that of the normal fetuses. Unilateral LD flap in a 22-week-old fetus with a large MMC was evaluated as insufficient to close the defects. Conclusion: Ten percent shrinkage in the area of LD might be too critical to be disregarded by surgeons during the closure of MMC defects. The dimensional findings about LD (area, length, and width) may be helpful in planning of LD flap harvesting for the repairs of MMC.
Multiple Muscular Abnormalities in a Fetal Cadaver With Charge Syndrome
(Springer France, 2019) Beger, Orhan; Koc, Turan; Beger, Burhan; Ozalp, Hakan; Hamzaoglu, Vural; Vayisoglu, Yusuf; Olgunus, Zeliha Kurtoglu
The CHARGE syndrome characterized by coloboma, heart defects, atresia of the choanae, retarded growth, genitourinary hypoplasia, and ear anomalies is one of the rare syndromes. Although certain clinical issues (scapular winging, sloping shoulder, Sprengel's deformity, kyphosis and scoliosis) which could be related to abnormalities in musculoskeletal structures of the neck and shoulder have been identified in CHARGE syndrome, data on details of muscle anomalies seem to be quite limited in the literature. In this case report, bilateral multiple muscular abnormalities (agenesis of the trapezius, presence of the rhombo-atloid muscle, and presence of the bipartite rhomboid minor with superficial and deep parts) was presented in a fetus cadaver with atypical CHARGE syndrome to attract the attention of clinicians for definitive diagnoses and surgical reconstruction of the shoulders deformity such as scapular winging and Sprengel's deformity. By considering the previous studies, we propose that the absence of the trapezius, as well as the other muscle abnormalities around the neck and shoulder, should be revised as being a component of CHARGE syndrome.
