This study aims to investigate the relationship between frontal sinus volume and lateral lamella angle.Methods: 150 computed tomography scans of paranasal sinuses (300 sides) were retrospectively reviewed. Pneumatization patterns were classified according to volume using a three-dimensional reconstruction analysis of the frontal sinuses. The angle formed between the lateral lamella and the horizontal plane in continuation with the cribriform plate was measured and grouped according to Gera classification based on the hypothetical risk of iatrogenic injury. Analysis of these measurements was conducted.Results: A positive correlation was found between frontal sinus volume and lateral lamella angle. Hyperplastic frontal sinuses were the most prevalent followed by middle-sized sinuses. 5% of the frontal sinuses were aplastic. Lateral lamella angles ranging from 45 to 80 degrees (Gera class II) were the most common. Aplastic and hypoplastic frontal sinuses were common in subjects with less than 45 degrees lateral lamella angles (Gera class III). Males had significantly higher frontal sinus volumes and lateral lamella angles than females, while the influence of age was insignificant. Lateral lamella angles were significantly higher on the left side.Conclusion: The frontal sinus volume affects the lateral lamella angle. Larger frontal sinuses are associated with higher lateral lamella angles and vice versa. Understanding this anatomical relationship can help prevent surgical complications.","PeriodicalId":49461,"journal":{"name":"Surgical and Radiologic Anatomy","volume":"47 1","pages":"3"},"PeriodicalIF":1.4,"publicationDate":"2024-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142734097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Males demonstrated significantly higher values than females in terms of Zy-Zy (Zy = Zygion), nasal body, and width/length of the columella. Hyperleptoprosop types were the most frequently observed, followed by the leptoprosop type. Females exhibited megaseme characteristics according to OI on both sides. Additionally, the danger triangle of the face was greater in males compared than in females, suggesting a higher risk of infection in this region among males.Conclusion: The observed sex differences in facial and nasal dimensions, along with facial indices, are crucial for customizing surgical procedures to individual patients. For example, the greater distance in the danger triangle among males highlights the importance of considering anatomical variations to avoid complications, such as septic cavernous sinus thrombosis. Integrating these measurements into preoperative planning can enhance the precision of facial reconstruction and aesthetic surgeries, thereby improving patient outcomes and safety.","PeriodicalId":49461,"journal":{"name":"Surgical and Radiologic Anatomy","volume":" ","pages":"1811-1823"},"PeriodicalIF":1.4,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142114066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When appendicitis happens in subhepatic caecum, it can be misdiagnosed and can lead to severe complications during surgical procedures. Therefore, this study aimed to understand the histomorphometric development of the appendix and caecum and to identify when lymphoid follicles appear in the appendix during fetal life.Methods: The study was conducted on a total of 50 fetuses. The caecum and appendix were carefully dissected. Their position and various measurements were observed. Afterwards, the appendix was taken out for histological processing. All three layers, mucosa, submucosa, and muscularis externa were measured using Image Analyzer Software Image Pro Premiere 9.1, and the appearance of lymphoid follicles was also examined. Results were analyzed using SPSS statistical software.Results: During the 1st, 2nd, and 3rd trimesters the most common caecum type was type 1: as a lengthy tube, type 3: The lateral wall expanded more, thus it has an asymmetric saccule, and type 4: adult-like caecum. The caecum was mostly situated in the right lumbar region in the 2nd and 3rd trimesters. In the 1st trimester, it was subhepatic in position. The most common position of the appendix was 11 o'clock in 1st and 3rd trimesters. 2nd trimester's most common position of the appendix was 12 o'clock. The thickness of the mucosa, submucosa, and the muscularis externa increases as the trimester increases. The lymphoid follicles have appeared during the 2nd trimester.Conclusion: The knowledge from this study will be useful in the diagnosis and treatment of malformations, pathology, and anomalies of the caecum and appendix due to congenital causes.","PeriodicalId":49461,"journal":{"name":"Surgical and Radiologic Anatomy","volume":" ","pages":"1875-1883"},"PeriodicalIF":1.4,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11458631/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142308910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The \"normal\" branches of the CIA principally consist of subangiographic rami supplying neighboring structures. Larger branches participate in the vascularization of the psoas muscle and the ureter. Less often, the CIA provides anomalous branches that complement or replace critical neighboring vessels. This study investigates the prevalence, type, and clinical relevance of CIA branches detectable during pelvic angiography.Methods: This study analyzes the prevalence of CIA branches in 100 consecutive angiograms that included bilateral CIA injections as well as selective catheterizations of the median sacral artery, both L4 ISAs, and both internal iliac arteries. CIA branches were classified as normal (i.e., neither supplementing nor replacing a normal artery), accessory (i.e., supplementing a normal artery), or aberrant (i.e., replacing a normal artery).Results: Forty-three branches arose from 38 CIAs (19% of CIAs) in 30 patients (30% of patients), including 20 normal branches (46.5%), 21 aberrant branches (48.8%), and 2 accessory branches (4.7%). Each of the 15 patients with aberrant branches had at least one anomalous vessel capable of providing a radicular or radiculomedullary artery.Conclusions: CIA branches were present in 30% of patients undergoing spinal angiography. While most normal branches were diminutive and clinically irrelevant, CIAs also provided vessels able to vascularize pelvic and vertebral structures, including the spinal cord or a spinal vascular malformation in 16% of cases. Our study therefore confirms that CIA injections represent an essential component of pelvic and spinal angiography.","PeriodicalId":49461,"journal":{"name":"Surgical and Radiologic Anatomy","volume":" ","pages":"1845-1857"},"PeriodicalIF":1.4,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142331015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CTA and DSA revealed a large FVA involving the V3 and V4 segments. Additionally, we observed bilateral duplicated SCAs originating from the distal basilar artery.Discussion: FVA is a rare anomaly resulting from fusion failure during the embryological period, with a reported incidence of 0.1%. FVA is often (70%) detected in the extracranial region, but it can also occur intracranially at a frequency of approximately 30%. Although various nomenclatures are used in the literature, we identified only two reports of a single fenestration encompassing the V3 and V4 segments, i.e., involving both the extracranial and intracranial regions. While duplication of the SCA is relatively common, bilateral duplication of SCA occurs at a rate of 0.9-5%.Conclusion: This case report describes an unusual case of VA fenestration involving both extracranial and intracranial segments, along with bilateral duplication of the SCAs. While rare, these findings highlight the importance of recognizing such vascular anomalies, which could be relevant for planning surgical or endovascular procedures in the posterior circulation.","PeriodicalId":49461,"journal":{"name":"Surgical and Radiologic Anatomy","volume":" ","pages":"1801-1805"},"PeriodicalIF":1.4,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142120975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
