Application of 3D Printing in Cleft Lip and Palate Repair.

This manuscript reviews the transformative impact of 3-dimensional (3D) printing technologies in the treatment and management of cleft lip and palate (CLP), highlighting its application across presurgical planning, surgical training, implantable scaffolds, and postoperative care. By integrating patient-specific data through computer-aided design and manufacturing, 3D printing offers tailored solutions that improve surgical outcomes, reduce operation times, and enhance patient care. The review synthesizes current research findings, technical advancements, and clinical applications, illustrating the potential of 3D printing to revolutionize CLP treatment. Further, it discusses the future directions of combining 3D printing with other innovative technologies like artificial intelligence, 4D printing, and in situ bioprinting for more comprehensive care strategies. This paper underscores the necessity for multidisciplinary collaboration and further research to overcome existing challenges and fully utilize the capabilities of 3D printing in CLP repair.

A NSQIP study comparing surgical outcomes between primary and non-primary TEPs after total laryngectomy.

OBJECTIVE: Tracheoesophageal puncture with voice prosthesis (TEP) is considered the gold standard for voice rehabilitation after total laryngectomy; however, there is debate as to whether it should be inserted concurrently with removal of the larynx (primary TEP), or as a separate, additional procedure at a later date (secondary TEP). We utilized the National Surgical Quality Improvement Program Database (NSQIP) to compare postoperative complications, readmission rates, and reoperation rates among individuals who underwent total laryngectomy with or without concurrent TEP placement. METHODS: We conducted a retrospective study using the American College of Surgeons National Surgical Quality Improvement Program database (ACS-NSQIP) from 2012 to 2019. Patients were categorized into primary and non-primary TEP groups using a variation of CPT codes for total laryngectomy, tracheoesophageal prosthesis, and type of reconstruction. Univariate analyses were performed and significance was determined at p < 0.05. RESULTS: A total of 1974 patients who underwent total laryngectomy were identified from the database: 1505 (77.3 %) in the non-primary TEP group and 442 (22.7 %) in the primary TEP group. Patients in the non-primary TEP group were more likely to have an ASA class greater than or equal to three (91.2 % primary vs. 84.6 % non-primary, p < 0.001). Patients in the non-primary TEP group were also more likely to require intraoperative or postoperative blood transfusions within the first 72 h of surgery (20.5 % non-primary vs. 15.3 % primary, p = 0.016). Both groups had similar rates of wound breakdown and dehiscence. There remained no significant difference based on type of reconstruction. CONCLUSIONS: This study suggests that patients receiving primary TEPs are not at a greater risk of developing wound complications such as pharyngocutaneous fistulas in the 30-day postoperative period. This remained true when patients were stratified by type of flap reconstruction. Patients in the non-primary TEP group were more likely to have an ASA category of 3 or greater, which may explain why they experienced higher rates of complications such as blood transfusions intra-operatively or post-operatively.

Intensified Adjuvant Treatment for High-Risk Resected Cutaneous Angiosarcoma of the Head and Neck.

OBJECTIVE: Previous studies have highlighted the poor survival of patients with cutaneous angiosarcoma of the head and neck. Therapeutic options are limited, and effective treatment strategies are yet to be discovered. The objective of this study is to evaluate overall survival following intensified adjuvant treatment for high-risk resected angiosarcoma of the head and neck. STUDY DESIGN: Retrospective observational. SETTING: National Cancer Database (NCDB). METHODS: Patients diagnosed with nonmetastatic cutaneous angiosarcoma of the head and neck from 2004 to 2016 were identified by NCDB. We retrospectively compared demographics and overall survival between patients who received surgery and radiation therapy (SR) and patients who received surgery and chemoradiation (SRC). The χ2 test, Kaplan-Meier method, and Cox regression models were used to analyze data. RESULTS: A total of 249 patients were identified, of which 79.5% were treated with surgery and radiation alone and 20.5% were treated with surgery and chemoradiation. The addition of chemotherapy, regardless of the sequence of administration, was not associated with significantly higher overall survival. Factors associated with worse survival in both groups included positive nodal status and positive margins. Patients with positive nodes had higher overall survival with radiation doses >50.4 Gy compared to ≤50.4 Gy (hazard ratio: 2.93, confidence interval: 1.60-5.36, p < 0.001). CONCLUSION: Adjuvant chemotherapy was not significantly associated with higher overall survival for resected nonmetastatic angiosarcoma of the head and neck. Higher radiation doses appear to be prognostic for high-risk diseases.

Invasive Intracranial Electroencephalogram (EEG) Monitoring for Epilepsy in the Pediatric Patient With a Shunt.

The use of invasive intracranial electroencephalogram (EEG) monitoring in the patient with a cerebrospinal fluid (CSF) diversionary shunt presents a conundrum -- the presence of a percutaneous electrode passing into the intracranial compartment presents a pathway for entry of pathogens to which a chronically implanted device like a shunt is especially susceptible to infection. In this case report, we describe the clinical and radiological features, medical and surgical management, and treatment outcomes of pediatric patients with shunted hydrocephalus who underwent invasive intracranial monitoring over an eight-year period. Three cases of children undergoing invasive intracranial monitoring were included in this study. Invasive monitoring for each patient occurred over three to six days. In each case, invasive intracranial monitoring was completed successfully, without resulting infection or shunt malfunction. While the second procedure was complicated by the formation of a pneumocephalus, there was no associated midline shift, and invasive intracranial monitoring was completed without incidence. Each patient received further surgery that successfully reduced seizure frequency. This study suggests that, while children with CSF diversionary shunts are at an inherently increased risk for infection and other complications, invasive intracranial monitoring is a relatively safe and feasible option in these patients. Future studies should explore the optimal duration for intracranial monitoring in pediatric patients with chronically implanted devices.

Orthopedic Surgery Residency Program Website Content and Accessibility During the COVID-19 Pandemic: Observational Study.

BACKGROUND: The exceptional competitiveness of the orthopedic surgery specialty, combined with the unclear impact of the COVID-19 pandemic on residency recruitment, has presented significant challenges to applicants and residency program directors. With limited in-person opportunities in the 2020-2021 application cycle, applicants have been pressed to gauge chances and best fit by browsing program websites. OBJECTIVE: The aim of the study was to assess the accessibility and content of accredited orthopedic surgery residency program websites during the COVID-19 pandemic. METHODS: Using the online database of the Electronic Residency Application Service (ERAS), we compiled a list of accredited orthopedic surgery residency programs in the United States. Program websites were evaluated across four domains: program overview, education, research opportunities, and application details. Each website was assessed twice in July 2020, during a period of adjustment to the COVID-19 pandemic, and twice in November 2020, following the October ERAS application deadline. RESULTS: A total of 189 accredited orthopedic surgery residency programs were identified through ERAS. Of these programs, 3 (1.6%) did not have functional website links on ERAS. Data analysis of content in each domain revealed that most websites included program details, a description of the didactic curriculum, and sample rotation schedules. Between the two evaluation periods in July and November 2020, the percentage of program websites containing informative videos and virtual tours rose from 12.2% (23/189) to 48.1% (91/189; P<.001) and from 0.5% (1/189) to 13.2% (25/189; P<.001), respectively. However, the number of programs that included information about a virtual subinternship or virtual interview on their websites did not change. Over the 4-month period, larger residency programs with 5 or more residents were significantly more likely to add a program video (P<.001) or virtual tour (P<.001) to their websites. CONCLUSIONS: Most residency program websites offered program details and an overview of educational and research opportunities; however, few addressed the virtual transition of interviews and subinternships during the COVID-19 pandemic.
