Large metacarpal and phalangeal bone defects are a hot topic for orthopedic surgeons due to its high clinical incidence, disability rate, and postsurgical amputation rate, along with its difficult treatment, long treatment course, high cost, and poor effect, all of which have a negative impact on the appearance and function of the patient's hands. There are currently a variety of treatment options for large metacarpal and phalangeal bone defects, each with its own benefits and drawbacks. However, there is no treatment method capable of perfectly resolving all the problems of patients with these defects. In this paper, the authors introduce several common plans for and progress of large metacarpal and phalangeal bone defect treatment.

Objective: To determine alterations in the crista galli (CG) size in fetuses with advancing weeks.

Methods: Skull bases of 32 fetuses (11 males/21 females) aged 17 to 32 weeks in utero were included in the study. The width (width of CG), height (height of CG), and length (length of CG) of CG were measured, and also olfactory fossa depth (OFD) was measured to determine the relation of CG with OFD.

Results: Width of CG, height of CG, length of CG, and OFD were measured as 1.77 ± 0.59 mm, 5.10 ± 1.70 mm, 12.32 ± 2.25 mm, and 1.56 ± 0.56 mm, respectively. No significant difference was observed between the measurements in terms of sex and side ( P > 0.05). Apart from OFD, the parameters were greater in the third-trimester fetuses than in the second-trimester fetuses ( P < 0.001). Olfactory fossa depth was similar in both trimester fetuses ( P = 0.798). Olfactory fossa depth did not alter with advancing gestational weeks ( P = 0.077), but the others increased ( P < 0.01). Only one configuration regarding Keros types was observed. Type 1 was detected in all fetuses (100%). A linear function was calculated as y=1.442+0.455×age for the length of CG, y=-2.566+0.321×age for the height of CG, y=0.641+0.039×age for OFD, and y=-1.088+0.119×age for the width of CG.

Conclusions: Crista galli size increased with advancing fetal weeks. The authors detected Keros type 1 in all fetuses. The authors' linear functions representing the growth pattern of CG and OFD in fetuses may be useful in estimating their dimensions.

Hyaluronic acid injection for chin augmentation presents a minimally invasive technique that has garnered increasing popularity. Although the chin region is generally regarded as relatively safe with a lower likelihood of ischemic complications, it is imperative to recognize that severe adverse events can still arise due to variations in vascular or bone structures. This article documents a rare case of necrosis affecting the chin skin, floor of the mouth, and tongue after hyaluronic acid injection for chin augmentation, which was successfully managed with reconstituted hyaluronidase injection.

Robotic-assisted microsurgery has emerged as a transformative technology, offering enhanced precision for complex procedures across various fields, including lymphatic surgery, breast reconstruction, trauma, and neurosurgery. This paper reviews current advancements, applications, and potential future directions for robotic-assisted microsurgery. In lymphatic surgery, robotic systems such as Symani have improved precision in thoracic duct reconstruction and lymphatic vessel anastomoses, reducing morbidity despite longer surgery times. In breast reconstruction, robotic systems are being used to refine techniques like the miraDIEP approach, minimizing tissue damage and enhancing precision in individualized treatments. Trauma reconstruction, particularly for extremities, has also benefited from robotic assistance, enabling successful sutures in small vessels and nerves. Emerging applications in meningeal lymphatics show potential for treating neurodegenerative diseases through improved drainage. In neurosurgery, robots enhance precision in deep and narrow anatomic spaces, although advancements in specialized instruments are needed for full implementation. Future development of robotic microsurgery systems will focus on improved maneuverability, miniaturization, and integration of tools like augmented reality and haptic feedback. The goal is to combine robotic precision, data storage, and processing with human skills such as judgment and flexibility. Although robots are unlikely to replace surgeons, they are poised to play an increasingly significant role in enhancing surgical outcomes. As the technology evolves, further research and clinical trials are needed to refine robotic systems and validate their expanding applications in clinical practice.

The aim of the study was to investigate the incidence and diversity of deformational auricular anomalies in human fetuses based on their morphologic appearances. A total of 100 auricles from 56 formalin-fixed fetuses (32 female and 24 male), gestational ages ranging from 17 to 36 weeks, were examined. The auricles were categorized according to the morphologic deformities outlined in existing literature. Of the samples analyzed, 67% exhibited auricular deformities, while the remaining 33% showed no auricle anomalies. Among the auricles with deformities, 73% displayed a single type of deformity: Conchal crus, 22%; Stahl's ear, 13%; inverted conchal bowl, 13%; lidding ear, 12%; cup ear, 7%; and constricted ear, 6%. In addition, 27% of the auricles exhibited 2 different deformities on the same side: Conchal crus with lidding ear, 10%; conchal crus with Stahl's ear, 5%; conchal crus with the antihelix 3rd crus, 3%; constricted ear with lidding ear, 5%; constricted ear with cup ear, 2%; and constricted ear with inverted conchal bowl, 2%. The most prevalent deformity was conchal crus, whereas cup ear was the least. Among the fetuses, 10 had bilaterally normal auricles, 8 had unilaterally normal auricles, 12 exhibited the same deformity bilaterally, and 14 displayed different deformities on each side. Auricular deformational variations can vary in shape and symmetry, even in morphologically normal fetuses. Identifying these deformities can contribute to accurate diagnosis and treatment planning for such anomalies in newborns.

Parents of children with craniosynostosis may experience psychological distress, particularly during intensive periods of treatment. Yet, recent research indicates parents may not be accessing the support they need to cope with common challenges. The aim was to develop an evidence-based booklet to promote psychological health in families undergoing surgery and to assess the acceptability of the booklet among the craniosynostosis community. Researchers collaborated with UK charity Headlines Craniofacial Support, 5 parent representatives, and 2 specialist clinical psychologists to develop the booklet based on data obtained from online focus groups, individual interviews, and written accounts. The draft booklet was attached to an online acceptability survey and distributed to a broader group of parents and multidisciplinary craniofacial specialists for feedback. A total of 52 complete responses to the online acceptability survey were received, and acceptability (measured by the number of respondents who would recommend the booklet) was 100%. All respondents supported the UK-wide distribution of the booklet. Evidence for psychological intervention in the craniofacial field remains scarce, and specialist teams may be under-resourced to effectively screen and support families. It is hoped this booklet can begin to address the gap in psychological support for families affected by craniosynostosis.

The vascularized iliac crest flap has garnered widespread acclaim within the field of mandibular reconstruction attributable to its sufficient bone mass and congruent curved morphology. However, when the precise orientation of the iliac crest is imperative during mandibular reconstruction and there exists an accompanying defect within the oral soft tissue, the indispensability of an additional flap to facilitate concurrent defect repair becomes evident. In such instances, the submental island flap emerges as an exemplary candidate.

Objective: The aim of this study is to assess maxillary transverse dimension following presurgical maxillary segmented orthodontics associated with 3-piece Le Fort 1 osteotomy in a cohort of "long face syndrome" patients with palatal constriction.

Methods: Patients with maxillary transverse insufficiency were retrospectively included. They all underwent maxillary segmented orthodontics followed by a 3-piece Le Fort 1 osteotomy with palatal expansion. Palatal width dimensions were collected preoperatively, postoperatively, and at the time of the final follow-up, the stability of the expansion was analyzed.

Results: Nineteen patients were included. There was no complication. The mean postoperative expansion was 6 mm (range: 3.1-8.7 mm) in the canine region and 4.3 mm (range: 0-9.1 mm) in the second molar region. The mean relapse was 0.36 mm (range: 0-1.4 mm) or 6% (range: 0%-16.1%) in the canine region and 0.17 mm (range: 0-1.3 mm) or 4% (range: 0%-14%) in the second molar region.

Conclusion: Presurgical maxillary segmented orthodontics with 3-piece Le Fort 1 osteotomy has shown high stability of the maxillary transverse dimension in a 1-step surgery without dental tipping. It should be considered as an alternative to rapid palatal expansion.

Atherosclerosis (As) is an important pathologic basis for ischemic cerebrovascular disease and easily causes stenosis of the origin of the internal carotid artery (ICA). As the main source of intracranial blood supply, the ICA accounts for 70% to 80% of blood flow. This stenosis can cause various ocular symptoms in patients. In the existing literature, it is rare to report cases with only acute vision loss caused by ICA plaque hemorrhage combined with thrombosis. The authors report a case of acute vision impairment caused by ICA plaque hemorrhage. The clinical manifestations, imaging characteristics, differential diagnosis, and treatment methods were discussed based on relevant literature, and the diagnosis and differentiation of the disease were considered to deepen the understanding of the disease.

Different surgical techniques have been explored over time to treat children with scaphocephaly. The objective of this study is to compare morbidity and cosmetic outcomes in total cranial vault remodelling (TCVR) and minimally invasive suturectomy with postoperative helmet therapy (MISPH) in patients with scaphocephaly. The authors performed a retrospective comparative cohort study, including 43 patients with isolated sagittal craniosynostosis who underwent TCVR (n=17) or MISPH (n=26) at the Antwerp University Hospital between April 2008 and December 2022. MISPH was associated with significantly shorter procedure duration (TCVR 199 ± 48 min, MISPH 69 ± 12 min, P <0.001), decreased blood loss (TCVR 610 ± 298 mL, MISPH 85 ± 73 mL, P <0.001) and lower transfusion rate (TCVR 100%, MISPH 54%, P <0.001). Mean length of stay at the intensive care unit and the hospital were significantly shorter after MISPH (TCVR 6 ± 1 d, MISPH 3 ± 0.5 d). The change in CI after TCVR was significantly larger than after MISPH during the first postoperative year. However, the CI in the MISPH group was significantly higher during the first year compared with the TCVR group. Mean CI of the MISPH group reached normal limits during the first year, while in the TCVR group, mean CI reached normal values 5 years after surgery. The authors could not find a statistically significant difference in cosmetic outcome between the 2 groups. The authors conclude that MISPH is associated with decreased morbidity and comparable cosmetic results when compared with TCVR in the treatment of scaphocephaly.
