In this study, data related to the total soft tissue thickness and fat layer thickness of 41 anatomical landmarks were extracted from the craniofacial computerized tomography data of 280 Chinese individuals (160 males and 120 females). The measurements were assessed according to the following factors a. sex, b. age, and c. sex × age. Descriptive statistics and a differential analysis were carried out in each group to analyze both the total soft tissue thickness and fat layer thickness. The results showed the following. 1. The results showed that the greater the total thickness of the soft tissue, the thicker the fat layer. 2. The thicknesses of the head and face soft tissues are strongly affected by sex. The total thickness of all landmark points in the men, except for the zygomatic points, was on average greater than that in the women. In contrast to the total thickness, the fat layer, except for the point of rhinion, in the women was larger than that in the men. 3. In the comparison of the 4 age groups, msults showed that the greater the total thickness of the soft tissue, the thicker the fat layer. 2. The thicknesses of the head and face soft tissues are strongly affected by sex. The total thickness of all landmark points in the men, except for the zygomatic points, was on average greater than that in the women. In contrast to the total thickness, the fat layer, except for the point of rhinion, in the women was larger than that in the men. 3. In the comparison of the 4 age groups, most feature points did not show an evident increasing or decreasing trend with age in the total thickness of the soft tissue. However, regarding the thickness of fat, the thickness at the other points, except for the feature infraorbital fossa point, decreased with age. 4. In the analysis of the sex × age group, no statistically significant differences were found at any landmark points. This paper is significant for facial reconstruction and cosmetic surgery in the Chinese population.
In this retrospective study, the authors determined changes in intracranial volume (ICV) and cephalic index (CI) in patients with sagittal craniosynostosis and operated with craniotomy combined with either 2 or 3 springs. The authors included patients (n = 112) with complete follow-up that had undergone surgical correction for isolated sagittal craniosynostosis with craniotomy combined with springs between 2008 and 2017. All patients underwent computed tomography examination preoperative, at the time of spring extraction, and at 3 years of age. Intracranial volume was measured using a semiautomatic MATLAB program, and CI was calculated as the width/length of the skull. The authors found that craniotomy combined with 2 springs increased the ICV from a preoperative value of 792 ± 113 mL (mean ± standard deviation) to 1298 ± 181 mL at 3 years of age and increased the CI from 72.1 ± 4.1 to 74.6 ± 4.3, whereas craniotomy combined with 3 springs increased the ICV from 779 ± 128 mL to 1283 ± 136 mL and the CI fromtained at 3 years of age.
By measuring velopharyngeal structure and evaluating speech intelligibility, to explore and observe the association between velopharyngeal anatomy and speech outcomes in these patients.
Thirty-one adult patients with velopharyngeal insufficiency after the primary palatoplasty aged 18 to 35 years (mean 22.03 years) were enrolled as the study group. The patients had significant hypernasality and audible nasal emission. The degree of velopharyngeal closure assessed by electronic nasopharyngeal fiberoptic endoscopy was grade III. Cephalometric analysis was performed on lateral cephalograms to measure velopharyngeal structure, including hard palate length (ANS-PNS), velar length (PNS-U), pharyngeal depth (PNS-PPW), and oropharyngeal airway space (U-MPW). Their speech intelligibility was evaluated through the Mandarin Chinese speech intelligibility test, and each speech sample was examined by 2 speech and language pathologists. The results were assessed with the SPSS 23.0 software package, and regression analyscy, this is consistent with our clinical observation. It suggests that appropriate reduction of pharyngeal depth during palatopharyngoplasty may have a good effect on the speech recovery in patients with cleft palate and patients with velopharyngeal insufficiency after palatorrhaphy.
Anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis is a form of autoimmune encephalitis associated with EEG abnormalities. In view of the potentially severe outcomes, there is a need to develop prognostic tools to inform clinical management. The authors explored whether quantitative EEG was able to predict outcomes in patients with suspected anti-NMDAR encephalitis.
A retrospective, observational study was conducted of patients admitted to a tertiary clinical neuroscience center with suspected anti-NMDAR encephalitis. Peak power and peak frequency within delta (<4 Hz), theta (4-8 Hz), alpha (8 - 13 Hz), and beta (13-30 Hz) frequency bands were calculated for the first clinical EEG recording. Outcome was based on the modified Rankin Scale (mRS) score at 1 year after hospital discharge. Binomial logistic regression using backward elimination was performed with peak frequency and power, anti-NMDAR Encephalitis One-Year Functional Status score, age, and interval from symptom onset to EEG entered ody encephalitis, thereby serving as a useful adjunct to qualitative EEG assessment; however, given the small sample size, replication in a larger scale is indicated.
In this exploratory study, it was found that quantitative EEG on routinely collected EEG recordings in patients with suspected anti-NMDAR encephalitis was feasible. A higher peak frequency within the delta range was associated with poorer clinical outcome and may indicate anti-NMDAR-mediated synaptic dysfunction. Vorinostat purchase Quantitative EEG may have clinical utility in predicting outcomes in patients with suspected NMDAR antibody encephalitis, thereby serving as a useful adjunct to qualitative EEG assessment; however, given the small sample size, replication in a larger scale is indicated.
The intrarectal suture is considered a high technically complex procedure. The study's objectives were to assess the feasibility of making an intrarectal knot, through an in vitro study and assessing whether the video tutorial facilitates learning.
A detailed description of the technique. A comparative observational cross-sectional study in surgeons with no previous experience in intrarectal knots.
Twenty-one of these 32 participants passed the intrarectal knot test without video tutorial (T1) (65.6%), and 26 (81.2%) after the video tutorial (T2) (P=0.26). The mean time taken to tie the knot fell from 74 seconds (SD=46) in T1 to 41 seconds (SD=41) in T2 (P<0.001). At T1, 26 participants (81.3%) described the technique as difficult, but only 7 (21.9%) at T2 (P<0.001).
Performing the intrarectal knot suture is feasible. Despite the technical difficulty, the video tutorial is sufficient for surgeons to learn the technique.

Plain radiographic evaluation remains the standard initial assessment of patellar instability, while 3-dimensional imaging is obtained in some patients. Merchant radiographs can demonstrate the tibial tubercle relative to the trochlear groove (TT-TG), but the determination of the TT-TG from these radiographs has been abandoned since its original description. The purpose of this study is to evaluate the utility of the TT-TG measured on Merchant radiographs for the assessment of patellar instability.
A prospective cohort study was performed of pediatric and adolescent patients aged 10 to 18 who underwent standardized Merchant radiographs, including a total of 98 knees (in 57 patients). Merchant TT-TG was measured as the distance between the center of the trochlear groove and the tibial tubercle, with both lines perpendicular to the anterior femoral condylar axis. In Part 1, the Merchant TT-TG measured by the tibial tubercle radiographic appearance was compared with the measurement utilizing a radiographic mifferentiating patients with and without patellar instability.
Standardized Merchant radiographs allow for reliable assessment of the Merchant TT-TG distance when the tibial tubercle is visualized and moderately correlate with MRI TT-TG (with Merchant TT-TG on average 4.5 mm less than MRI).

Forearm nonunion is a rare condition in children, and its treatment is usually successful. However, nontraumatic nonunion can be resistant to treatment. Although the vascularized fibular bone graft has been frequently used for complex forearm nonunion, there is no consensus on the best treatment method. In this study, we aimed to investigate the outcome of the antegrade posterior interosseous bone flap (PIBF) in treating children with complex radius nonunion.
The participants consisted of 3 girls and 1 boy ranging from 31 months to 9 years of age. They were treated with PIBF surgery, and the nonunion of the radius was fixed with a plate or an external fixator. The nonunion was due to congenital pseudoarthrosis, osteogenesis imperfecta, or infantile osteomyelitis. All patients were evaluated for a clinical and radiologic union.
The radiologic union was achieved 2 to 3 months after the surgery in all cases. The functional recovery of the elbow, forearm, and wrist was satisfactory except for 1 patient who experienced donor site fracture, and finally radioulnar synostosis accompanied by radial head dislocation.
Because of the simplicity of its technique and short duration of surgery, PIBF can be a reliable and less-demanding alternative to vascularized fibular bone graft in the treatment of complex forearm nonunion in children.

Discoid meniscus, a congenital meniscus variant, may have greater incidence in Asian populations. No US population-based studies have examined the discoid meniscus ethnic/racial distribution. In pediatric patients undergoing meniscus surgery, it is hypothesized that ethnic/racial variability exists in patients with discoid meniscus and this variability is different than in patients with medial meniscus tears.
The Pediatric Health Information System was queried from 48 hospitals to examine patients 18 years of age and younger between 2015 and 2019, using International Classification of Diseases, 10th Revision, Clinical Modification codes. A cohort of patients treated surgically for discoid meniscus was compared with a cohort of patients treated surgically for medial meniscal tear. These 2 populations were compared based on age, sex, ethnicity/race, Current Procedural Terminology code, insurance, urban versus rural, and region of country. Univariate testing and multivariable logistic modeling were used to ten made up a greater percentage of the population having surgery for a torn discoid meniscus versus a torn medial mensicus. When evaluating pediatric patients, younger age and Asian or Hispanic/Latino ethnicity should increase attention to the possibility of a discoid meniscus.
