AI Article Synopsis

  • The study examines the effectiveness of different sizes of forehead tissue expanders in improving reconstructive outcomes and minimizing donor site deformities following surgery.
  • It analyzed data from 79 patients who received either small (50/80 mL) or large (150/200 mL) expanders, finding no major demographic differences between the two groups.
  • Results indicated that larger expanders led to less frontal deformation and better overall reconstruction results, suggesting that larger expanders are preferable for forehead procedures.

Article Abstract

Background: Both reconstructive outcomes and donor site deformities should be considered in forehead expander selection for resurfacing facial skin defects. Cranial bone deformity as well as bone resorption always cannot be completely normalized after tissue expander extraction. This study aimed to investigate the correlation between the degree of frontal deformity, the reconstruction outcomes, and the expander size.

Patients And Methods: Cases of forehead tissue expansion performed from 2011 to 2020 with 50/80 mL sized expanders and 150/200 mL expanders were retrospectively reviewed and separated into 2 groups. Demographic and clinical data were collected. Two plastic surgeons (Y.Z. and L.L.) who were not involved in the operation process compared the patient's preoperative photos with their final follow-up photos. The Fisher exact, 2-sample t tests, and the Wilcoxon rank-sum test were performed in this study.

Results: Ultimately, 51 patients were included in the 50/80ml sized expander group, and 28 patients were included in the 150/200 mL expander group. Demographic data were collected and had no statistically significant differences between the 2 groups. There was no statistical difference in the frontal deformation rate between the 2 groups. The degree of frontal deformation was significantly different, and a large expander could significantly reduce the frontal deformation degree ( P < 0.05) and acquire a higher evaluation of the whole reconstruction outcomes ( P = 0.007).

Conclusions: The large-sized (150/200 mL) expander sited on the forehead was shown to have a slighter postoperative forehead change and better reconstruction effect. It is advisable to choose expanders with relatively larger sizes in the application of the forehead expand flap.

Brain Network Analysis Reveals Hemispheric Aberrant Topology in Patients with idiopathic REM Sleep Behavior Disorder.

Idiopathic rapid eye movement sleep behavior disorder (iRBD) is recognized as a prodromal stage of neuro-degenerative disease. While brain network analysis is a well-documented approach for characterizing disease-related dysfunctions, the specific patterns in iRBD, particularly those related to hemispheric aberrations remain largely unexplored. To address this gap, this study investigated the topological abnormalities of multi-band EEG networks in patients with iRBD.

Modified Infrabrow Blepharoplasty for Periorbital Rejuvenation in Asia Women.

J Craniofac Surg

December 2024

Department of Plastic Surgery, The First Affiliated Hospital, School of Medicine, Zhejiang University, Hangzhou.

Objective: The infrabrow blepharoplasty is a common surgical operation indicated in Asians for periorbital rejuvenation. This operation alone is difficult to achieve the correction of crow's feet. Therefore, the authors elucidate the authors' experiences of applying infrabrow blepharoplasty combined with the subcutaneous undermining of the lateral periorbital region to treat upper eyelid dermatochalasis with lateral hooding deformity and alleviate crow's feet, including its indications, operative procedures, and postoperative outcomes.

Background: Down syndrome (DS) is the most common congenital neurodevelopmental disorder, present in about 1 in every 700 live births. Despite its prevalence, literature exploring the neurobiology underlying DS and how this neurobiology is related to behavior is limited. This study fills this gap by examining cortical volumes and behavioral correlates in school-age children with DS.

Background: Frontoorbital distraction osteogenesis (FODO) is an established surgical technique for patients with unicoronal craniosynostosis. The authors' institution has used an endoscope-assisted technique (endo-FODO) in recent years to decrease cutaneous scarring and lessen the impact on the functional growth matrix. This study compared perioperative outcomes in patients undergoing endo-FODO to those in patients undergoing the traditional coronal approach.

Introduction: In an effort to maximize benefit and minimize morbidity when performing fronto-orbital distraction osteogenesis (FODO) for unilateral coronal synostosis (UCS), we have transitioned to an endoscopic-assisted approach ("endo-FODO"). This study compares photogrammetric outcomes of patients who underwent FODO via an endoscopic-assisted versus open approach.

Methods: We retrospectively reviewed patients treated for UCS from 2013 to 2023.
