Microvascular reconstruction demands specialized and additional training beyond residency. This study investigates the free flap learning curve at a newly established microsurgery center by analyzing free flap viability rate over 10 years. A retrospective review of free flap procedures performed between 2014 and 2024 by a single microsurgeon at a National Referral Hospital, Indonesia, was performed to assess free flap viability rates, flap types, and the relationships between specific flap choices and defect locations.

Background: Assessing perfusion in free flaps is crucial in clinical practice. Indocyanine green (ICG) angiography offers a more objective and reproducible method, utilizing near-infrared imaging to monitor flap vascularization. This study aims to evaluate the efficacy of diluted ICG as a tool for assessing free flap perfusion.

The management of micrognathia in adults necessitates intricate surgical procedures. A vascularized bone graft, notably the free fibular flap (FFF), offers a novel viable solution for repairing significant defects. However, the limited utilization of FFF in adult micrognathia contributes to gaps in understanding its outcomes.

Article Synopsis
- - The study investigates the optimal dose of indocyanine green (ICG) for evaluating free flap viability, traditionally set at 5 mg per mL, focusing on finding a lower concentration that maintains fluorescence quality using near-infrared cameras.
- - Conducted on 25 Wistar rats, researchers tested five ICG concentrations (from 5 mg to 0.5 mg per mL) and assessed the fluorescence visibility and flap vasculature through randomized videos rated by five microsurgeons.
- - Results indicated that while the 2.5 mg per mL concentration was the most favorable, there was no significant difference in performance between standard and diluted concentrations, suggesting potential for lower-cost ICG usage
Background: The long-term outcomes in pediatric patients with various extents of mandible defects have not been well-documented.
Methods: A retrospective case series in which this study looked at pediatric patients under the age of 13 who had mandibular reconstruction with free fibular flap and had not received another operation in the previous 6 months. The eating, swallowing, speech function, and quality of life are evaluated with EORTC QLQ-H&N35 after the mandible growth spurt has occurred.
