The Effectiveness of Three-Dimensional Osteosynthesis Plates versus Conventional Plates for the Treatment of Skeletal Fractures: A Systematic Review and Meta-Analysis.

PURPOSE: To assess the difference between preformed anatomically shaped osteosynthesis plates and patient-specific implants versus conventional flat plates for the treatment of skeletal fractures in terms of anatomical reduction, operation time, approach, patient outcomes, and complications. MATERIAL AND METHODS: MEDLINE (1950 to February 2023), EMBASE (1966 to February 2023), and the Cochrane Central Register of Controlled Trials (inception to February 2023) databases were searched. Eligible studies were randomised clinical trials, prospective controlled clinical trials, and prospective and retrospective cohort studies (n ≥ 10). Inclusion criteria were studies reporting the outcomes of preformed anatomically shaped osteosynthesis plates and patient-specific implants versus conventional flat plates after treating skeletal fractures. Outcome measures included anatomical reduction, stability, operation time, hospitalisation days, patients' outcomes, and complications. Two independent reviewers assessed the abstracts and analysed the complete texts and methodologies of the included studies. RESULTS: In total, 21 out of the 5181 primarily selected articles matched the inclusion criteria. A meta-analysis revealed a significant difference in operation time in favour of the preformed anatomical plates and patient-specific implants versus conventional plates. Significant differences in operation time were found for the orbital (95% CI: -50.70-7.49, p = 0.008), upper limb (95% CI: -17.91-6.13, p < 0.0001), and lower limb extremity groups (95% CI: -20.40-15.11, p < 0.00001). The mean difference in the rate of anatomical reduction in the lower limb extremity group (95% CI: 1.04-7.62, p = 0.04) was also in favour of using preformed anatomical plates and patient-specific implants versus conventional plates. CONCLUSIONS: This systematic review showed a significant mean difference in surgery time favouring the use of preformed anatomical plates and patient-specific implants for orbital, upper, and lower limb extremity fractures. Additionally, preformed anatomical plates and patient-specific implants in the lower limb group result in a significantly higher rate of anatomical reduction versus conventional flat plates.

Classification Systems of Cleft Lip, Alveolus and Palate: Results of an International Survey.

OBJECTIVE: This study aimed to identify commonly used classification systems by cleft providers around the world, including the perceived indications and limitations of each system. DESIGN: A cross-sectional survey. PARTICIPANTS: A total of 197 registrants from three international cleft/craniofacial meetings. INTERVENTIONS: Participants were sent a web-based questionnaire concerning cleft classification systems. MAIN OUTCOME MEASURES: Frequency of commonly used classification systems, their perceived indications and limitations. RESULTS: A total of 197 respondents from 166 different centers completed the questionnaire. Healthcare professionals from all disciplines responded, with the most frequent respondents being plastic surgeons (38.1%), maxillofacial surgeons (28.4%) and orthodontists (23.9%). Eighteen different classification systems were in use. The most frequently used systems were the International Statistical Classification of Diseases and Related Health Problems (ICD-10) (35.5%), LAHSHAL (34.0%), and Veau (32.5%) classification systems. Most respondents (32.5%) indicated that anatomical and morphological characteristics are essential components of a classification system. However, respondents indicated that their current classification systems lacked sufficient description of cleft extension and severity. CONCLUSIONS: Great variety in the use of classification systems exists among craniofacial specialists internationally. The results recommend the usage of the LAHSHAL classification of OFCs, due to its comprehensiveness, relatively high implementation rate globally, convenience of usage and complementarity with the ICD-10 system. Moreover, it can overcome deficiencies inextricably linked to ICD-10, such as incapacity to describe laterality and clefts of the alveolus. More international exposure to the merits of using the LAHSHAL classification system would be highly recommended.

The use and reliability of SymNose for quantitative measurement of the nose and lip in unilateral cleft lip and palate patients.

INTRODUCTION: It is essential to have a reliable assessment method in order to compare the results of cleft lip and palate surgery. In this study the computer-based program SymNose, a method for quantitative assessment of the nose and lip, will be assessed on usability and reliability. METHODS: The symmetry of the nose and lip was measured twice in 50 six-year-old complete and incomplete unilateral cleft lip and palate patients by four observers. For the frontal view the asymmetry level of the nose and upper lip were evaluated and for the basal view the asymmetry level of the nose and nostrils were evaluated. RESULTS: A mean inter-observer reliability when tracing each image once or twice was 0.70 and 0.75, respectively. Tracing the photographs with 2 observers and 4 observers gave a mean inter-observer score of 0.86 and 0.92, respectively. The mean intra-observer reliability varied between 0.80 and 0.84. CONCLUSIONS: SymNose is a practical and reliable tool for the retrospective assessment of large caseloads of 2D photographs of cleft patients for research purposes. Moderate to high single inter-observer reliability was found. For future research with SymNose reliable outcomes can be achieved by using the average outcomes of single tracings of two observers.

Best Practices for the Diagnosis and Evaluation of Infants With Robin Sequence: A Clinical Consensus Report.

IMPORTANCE: Robin sequence (RS) is a congenital condition characterized by micrognathia, glossoptosis, and upper airway obstruction. Currently, no consensus exists regarding the diagnosis and evaluation of children with RS. An international, multidisciplinary consensus group was formed to begin to overcome this limitation. OBJECTIVE: To report a consensus-derived set of best practices for the diagnosis and evaluation of infants with RS as a starting point for defining standards and management. EVIDENCE REVIEW: Based on a literature review and expert opinion, a clinical consensus report was generated. FINDINGS: Because RS can occur as an isolated condition or as part of a syndrome or multiple-anomaly disorder, the diagnostic process for each newborn may differ. Micrognathia is hypothesized as the initiating event, but the diagnosis of micrognathia is subjective. Glossoptosis and upper airway compromise complete the primary characteristics of RS. It can be difficult to judge the severity of tongue base airway obstruction, and the possibility of multilevel obstruction exists. The initial assessment of the clinical features and severity of respiratory distress is important and has practical implications. Signs of upper airway obstruction can be intermittent and are more likely to be present when the infant is asleep. Therefore, sleep studies are recommended. Feeding problems are common and may be exacerbated by the presence of a cleft palate. The clinical features and their severity can vary widely and ultimately dictate the required investigations and treatments. CONCLUSIONS AND RELEVANCE: Agreed-on recommendations for the initial evaluation of RS and clinical descriptors are provided in this consensus report. Researchers and clinicians will ideally use uniform definitions and comparable assessments. Prospective studies and the standard application of validated assessments are needed to build an evidence base guiding standards of care for infants and children with RS.

Tongue-lip adhesion in the treatment of Pierre Robin sequence.

OBJECTIVE: Pierre Robin sequence (PRS) is a congenital malformation in which micrognathia causes retroposition of the tongue. This results in feeding and breathing difficulties that can lead to severe complications. If conservative treatment is not sufficient, a surgical procedure such as a tongue-lip adhesion can be performed. The objective of this study was to evaluate our benefits and complications with this operation. SETTING: All patients under the care of the Department of Plastic and Reconstructive Surgery of the VU University Medical Center, Amsterdam, The Netherlands, in the period 1993 to 2002. PATIENTS: A consecutive series of 22 patients who needed operative intervention for PRS. All underwent a tongue-lip adhesion. METHODS: Retrospective analysis of the patient charts. Follow-up has been performed for a minimum of 1 year. RESULTS: In 16 (73%) of the patients operated on, feeding and breathing have improved. In 6 children, the results were limited because of concomitant congenital anomalies. Complications, all without lasting effect, were observed in 12 (55%) of the patients: 4 of 5 children with dehiscence of the adhesion needed reoperation, 6 developed small chin abscess that resolved after removal of the supporting suture, and 1 patient was reintubated for bronchospasm. CONCLUSIONS: Tongue-lip adhesion is a good surgical treatment for most children with PRS who have an isolated tongue-base airway obstruction. More invasive procedures such as mandibular distraction can be reserved for patients where a tongue-lip adhesion has not been successful.
