Objective: The gracilis muscle free flap has become a reliable means for smile reanimation for patients with facial paralysis. Because it is a buried flap, it presents a postoperative monitoring challenge. We sought to evaluate our experience with color Doppler ultrasound in the monitoring of gracilis free flap viability in the immediate postoperative setting.
Study Design: Case series with planned data collection.
Setting: Tertiary medical center.
Methods: Patients with facial paralysis treated with gracilis muscle free flap for smile reanimation performed between March 2009 and November 2010 were evaluated by color Doppler ultrasound and included in the study. Our experience with the use of the color Doppler ultrasound to monitor the gracilis muscle flap is presented.
Results: Forty-six patients were identified. In all cases, color Doppler ultrasound was used postoperatively to assess flow through the vascular pedicle. Outcomes included an early flap survival rate of 100%, with no instances of equivocal or absent flow on either the arterial or venous side. Color Doppler ultrasound provided important objective information regarding muscle perfusion postoperatively in several instances of equivocal postoperative perfusion of the flap.
Conclusion: Color Doppler ultrasound is a safe, noninvasive method that can be performed serially to evaluate a buried free flap. We have had success in verifying normal arterial and venous flow through the pedicle using this method of monitoring of the gracilis muscle free flap during facial reanimation, and in 3 instances, it eliminated the need for wound exploration to verify appropriate muscle perfusion.

Giant cell arteritis (GCA), a systemic vasculitis affecting large and medium-sized arteries, poses significant diagnostic and management challenges, particularly in preventing irreversible complications like vision loss. Recent advancements in artificial intelligence (AI) technologies, including machine learning (ML) and deep learning (DL), offer promising solutions to enhance diagnostic accuracy and optimize treatment strategies for GCA. This systematic review, conducted according to the PRISMA 2020 guidelines, synthesizes existing literature on AI applications in GCA care, with a focus on diagnostic accuracy, treatment outcomes, and predictive modeling.

Background: Mutations in the LARS2 gene are correlated with Perrault syndrome, a rare autosomal recessive genetic disorder, that is typically characterized by sensorineural hearing loss and ovarian insufficiency.
Methods: Whole-exome sequencing and mutational analysis were employed to identify hearing loss-causing genes in a Chinese family from the Guangxi Zhuang Autonomous Region. Clinical phenotypes, audiological data, and color Doppler ultrasound of the family were collected, and a series of computer software were used to analyze the impact of genetic variations on protein structure and function.

Patients at high risk of deep vein thrombosis are recommended to undergo lower-extremity ultrasonography to screen for pulmonary embolism (PE); however, there are few reports on whether this can effectively reduce the occurrence of fatal pulmonary embolism (FPE). This study aimed to assess the risk factors associated with PE and to investigate whether perioperative ultrasound screening of lower extremity veins in orthopedic patients can effectively reduce the incidence of FPE. We enrolled 137 patients with PE who underwent orthopedic surgery between 2013 and 2020.

Objectives: Surgical options for mitral valve repair in dogs are unstandardized and influenced by various factors. This study describes a four-point surgical technique (MI-4) to reduce mitral regurgitation and provides data from a study of dogs with 12 months of follow up.
Methods: Twenty-five dogs with stages C or D mitral insufficiency were treated by one of two surgeons using the MI-4 procedure at Ueno no Mori Animal Hospital between October 2021 and May 2023.
