Advanced technology and increasing knowledge about aging faces have combined to create the illusion of thread lifting to replace surgical interventions. However, results that came far beyond expectations led to a heavy suspicion of these tools. However, combined treatments with fillers would have better outcomes with a synergetic effect. In this study, 52 patients were treated with a specific thread, whereas soft tissue support was added to supervene the lifting effect of the threads. With a mean age of 48 years, these patients were treated with 3 pairs of mid and lower facial areas, and one for eyebrows. With a median amount of 5 mL fillers were added simultaneously at the same treatment plan. The follow-up period was 32 months. Assessment with a Likert Scale questionnaire revealed most of the patients (n = 42) were delighted, whereas only one patient was unsatisfied. The only unsatisfied patient experienced the most frustrating complication, which was thread removal due to infection. The literature shows unauthorized, unspecialized applications of such medical devices cause failure and loss of reliability. Therefore, the most important point of this technique is the sterile setting. Other issues that are discussed in this paper also aim to direct the reader to achieve the most benefit of these 2 techniques.

Background: This paper presents the authors' team's research on a craniofacial surgical robot developed in China. Initiated in 2011 with government funding, the craniofacial surgical robot project was officially launched in Shanghai, developed jointly by the Ninth People's Hospital affiliated with Shanghai Jiao Tong University School of Medicine and the Shanghai Jiao Tong University medical-engineering team. Currently, based on multiple rounds of model surgeries, animal experiments, and clinical trials, our team is applying for approval as a Class III medical device from the National Medical Products Administration (NMPA). As an innovative tool in the field of craniofacial surgery, it fills a technological gap within the country.

Methods: This study is a multicenter cohort study based on patient data from Shanghai Ninth People's Hospital from 2019 to 2024. Inclusion criteria included patients who underwent craniofacial surgery with complete follow-up data, with the primary variable being the use of robotic assistance in craniofacial surgery. Data analysis involved descriptive statistics, t tests, and multivariable regression, with a significance level set at P<0.05.

Results: The craniofacial surgical robot has been widely explored in the fields of congenital deformities, tumor reconstruction, and esthetic surgery. In the clinical trials discussed in this article, which included experiments on both craniofacial deformity correction surgeries and esthetic surgeries, a total of 39 patients were enrolled. In mandibular osteotomy surgery, robotic-assisted procedures can reduce osteotomy length error by an average of 2.2 mm and mandibular angle error by 9.09 degrees, while also decreasing the average surgery time by 10.43 minutes. In hemifacial microsomia distraction osteogenesis surgery, robotic-assisted surgery can reduce osteotomy length error by an average of 4.6 mm and shorten the average surgery time by 60 minutes. The robotic-assisted group also showed better perioperative outcomes for patients. The surgical precision was improved and there was a significant reduction in postoperative complications.

Conclusion: The authors' research team has completed the first multicenter study on craniofacial surgical robots in China, demonstrating that this robot significantly enhances surgical precision, reduces operation time, and improves perioperative patient indicators. These findings indicate that the robot is highly effective in assisting surgeons with complex procedures. The study suggests that, in the future, this robot is likely to be widely adopted in craniofacial surgery, significantly advancing surgical efficiency and precision, and bringing transformative progress to clinical practice.

Introduction: The surgical requirement for cleft lip and palate repair remains unmet in many developing areas of the world, including remote regions of Ghana. This article reviews the utilization of Internet education and online consultation for cleft lip and palate surgical training in Sunyani Regional Hospital (SRH), Ghana.

Methods: The cleft lip and palate treatment was promoted to patients in remote areas of Sunyani, Ghana region, through a charitable outreach program. These basic designs and settings were managed by local participants such as doctors, residents, nurses, and staff in SRH, Ghana.

Results: From November 2014 to December 2020, the authors collaborated in surgical treatment for 84 cases that were diagnosed with unilateral cleft lip, bilateral cleft lip, hard and soft palate cleft, and microstomia. The type of surgery has varied and has included cheiloplasty, palatoplasty, and others. The average scores of esthetic outcome evaluation were nasal form=2.4, symmetry of the nose=2.9, and vermillion border=2.9. Through the program, the surgeons and residents became significantly more proficient at cleft lip and palate surgery. The seminar topics have covered essential and sustainable topics based on SRH's current needs and showed the effectiveness in the current coronavirus disease-19 pandemic situation.

Conclusions: The shortage of orofacial cleft surgeons working in rural areas like Sunyani, Ghana, remains an obstacle that poses a challenge to any effort to improve health care quality in these rural communities. Sustainable remote education is essential for the training of local cleft surgeons to fill this local need; our collaborative and charitable program could be a recommended education design for cleft surgeons and institutes for their sustainable education.

Purpose: Previous studies have lacked a comprehensive analysis of imaging modalities for diagnosing Moyamoya disease (MMD). This study aims to bridge this gap by utilizing multi-modal imaging to provide a more detailed understanding of the clinical and imaging characteristics of MMD.

Methods: A retrospective analysis was conducted on seventy-eight adult MMD patients enrolled from March 2018 to March 2021. The study focused on clinical features, imaging findings, and treatment outcomes, with a particular emphasis on the comparative efficacy of different imaging modalities.

Results: In this series, clinical manifestations varied depending on the type of MMD, with intracerebral hemorrhage (ICH) being the most common (69.2%), followed by cerebral infarction (25.6%). Imaging techniques provided critical diagnostic insights: magnetic resonance imaging (MRI) demonstrated superior sensitivity over computed tomography (CT) in detecting hemorrhages, whereas computed tomography angiography (CTA) and digital subtraction angiography (DSA) identified intricate vascular lesions, including moyamoya vessels and aneurysms. Notably, cerebral perfusion imaging (CTP) highlighted significant differences in cerebral blood flow and volume between infarction and hemorrhage cases. This comprehensive imaging approach guided varied therapeutic strategies, including bypass surgery in 57 patients and interventional embolization for aneurysms in 14 patients.

Conclusion: The authors' findings underscore the critical role of early diagnosis using DSA, whereas highlighting CTA and MRA as valuable noninvasive tools for screening and follow-up. The integration of multi-modal imaging provides a detailed vascular assessment crucial for individualized patient management, facilitating timely interventions and significantly improving clinical outcomes.

Cranial vault remodeling (CVR) is a common procedure for correcting sagittal craniosynostosis. Some approaches leave significant craniectomy defects. The authors investigated the reosteogenesis in different cranial defect areas after CVR. A cross-sectional study was conducted in nonsyndromic sagittal craniosynostosis. Available early postoperative computed tomography (CT) scans were analyzed. The segmentation of three-dimensional reconstructed images was performed. Different cranial defect areas, including coronal, vertex, and occipital regions, were further investigated using an automated three-dimensional analysis software for reosteogenesis percentage. Forty-four CT scans were included. The average age at CVR was 8.8 months. The median time of postoperative CT scans was 6.1 weeks. The median bone reformation percentage of the entire cranial defect was 56.7%. Given the similar postoperative CT timing, the median bone reformation at the coronal, vertex, and occipital areas demonstrated 44.21%, 41.13%, and 77.75%, respectively ( P < 0.001). In the simultaneously removed coronal and lambdoid sutures, there were 45% with coronal and lambdoid sutures reformation, followed by lambdoid suture reformation alone, no suture reformation and coronal reformation alone in 35%, 20%, and 0%, respectively ( P = 0.013). There was no coronal reformation in the removed coronal suture group. However, 40% demonstrated lambdoid suture reformation after the isolated lambdoid suture removal. The occipital region has the highest reosteogenesis compared with the other cranial defects after CVR in nonsyndromic sagittal craniosynostosis. Within the removed previous patent sutures, the lambdoid suture reformation showed a higher rate than the coronal suture.

This study introduces a novel surgical technique that leverages digital design for the precise repair of mandibular defects resulting from benign jaw tumors. The restoration of the mandibular defect is accomplished through autologous bone grafting from the mandible itself. This method significantly diminishes surgical complexity and risk, meeting the patient's preference to avoid additional surgical sites. Notably, 15 months postsurgery, the patient's mandible dimensions were suitable for dental implantation. Therefore, this technique has proven effective in repairing mandibular defects caused by the excision of benign tumors.

Enhanced recovery after surgery (ERAS) protocols have informed perioperative care across multiple surgical specialties, optimizing patient outcomes through surgical stress management and accelerated recovery. This study evaluates the familiarity and adoption of ERAS elements among craniofacial and oral and maxillofacial surgeons in pediatric orthognathic surgery, a field where a formal ERAS protocol has not been established. A closed-ended survey of 102 surgeons was conducted to assess familiarity with and utilization of 14 ERAS elements. The survey garnered a 40.2% response rate, with 41 surgeons participating. The majority of respondents (68.3%) specialized in craniofacial (CF) surgery, and their annual pediatric orthognathic surgery caseload varied widely. Key findings revealed that 7 ERAS elements were widely adopted, including hypothermia prevention, normovolemia maintenance, intraoperative tranexamic acid use, and minimized opioid use for postoperative pain control. However, elements such as liposomal bupivacaine and postoperative goal-directed fluid therapy were less utilized, primarily due to limited availability or knowledge. Surgeons demonstrated high familiarity with elements like jaw immobilization and minimizing opioid use but showed knowledge gaps in areas such as preoperative nutritional screening and goal-directed fluid therapy. These insights underline the need for further education and the development of a standardized ERAS protocol tailored for pediatric orthognathic surgery. The study underscores the importance of multidisciplinary collaboration and comprehensive preoperative education in implementing ERAS protocols. This study serves as a foundation for future research into optimizing perioperative care for pediatric patients undergoing orthognathic surgery.

Introduction: Sarcomas are relatively rare malignant tumors of mesenchymal origin, representing only about 1% of tumors in the head and neck region.

Materials and methods: A retrospective study involved patients with sarcomas of the head and neck region who were diagnosed and treated over a 5-year period.

Results: Nine patients were included, 4 men and 5 women. The mean age of the patients was 51 years. Eight patients had soft tissue sarcomas, and 1 patient had osteosarcoma. The most common histologic types were dermatofibrosarcoma protuberans and angiosarcoma. Tumors presented predominantly with local symptomatology. All patients were treated only by surgical excision. No distant or regional metastases were found in any patient. Complete surgical excision was achieved in all cases, except in patients with chondrosarcoma of the nose and sinuses, who died due to local progression in the second year of follow-up. Other patients were disease-free during the observed period; a patient with osteosarcoma died in the fourth year of follow-up without recurrence of the malignant disease.

Conclusion: Large prospective and multicenter studies are necessary to provide relevant data on the distribution of different types of sarcoma in the head and neck region, their clinical behavior and response to therapeutic modalities, as well as on recurrence, presence of metastases, and survival.

This study was performed to clarify whether the superthin anterolateral thigh (ALT) flap is an appropriate choice for head and neck reconstructions requiring thinner and more pliable flaps. Data of patients who underwent head and neck reconstruction from January 2020 to December 2022 were retrospectively collected. Nine patients (4.2%) underwent reconstruction with a superthin ALT flap. All the flaps survived with no cases of total or partial necrosis. Six patients treated with superthin ALT flaps and 15 patients treated with conventional ALT flaps who underwent oral cavity reconstruction were compared. The mean body mass index was significantly higher in the superthin flap group than in the conventional ALT flap group (25.2 vs 21.2 kg/m 2 , respectively; P = 0.04). The rate of postoperative complications requiring debridement was 0% and 13% ( P = 0.37). The mean postoperative Hirose score was 9.7 and 8.7 ( P = 0.17). The mean postoperative Functional Oral Intake Scale score was 6.7 and 5.9 ( P = 0.12). Secondary flap refinement surgery after facial skin reconstruction was performed in 0 of 2 patients (0.0%) in the superthin flap group and 4 of 52 patients (7.7%) in the conventional ALT flap group ( P = 0.04). Oral cavity reconstruction with superthin ALT flaps did not increase the incidence of postoperative flap necrosis and resulted in comparable postoperative function. In addition, superthin ALT flaps did not require additional flap refinement surgeries after facial skin reconstruction. The superthin ALT flap is a safe and reliable choice for obese patients with thick thigh subcutaneous tissue.
