Does controlled, gradually increased venous pressure exposure (dangling) of the lower extremity after free flap reconstructions reduce partial flap loss? A multicenter randomized controlled trial.

Introduction: Controlled, gradually increased venous pressure exposure of lower extremity free flaps (dangling) is common, based on the assumption that this reduces (partial) flap loss. Dangling protocols potentially increase length of hospital stay and resource utilization. We investigated whether: (1) the proportion of partial flap loss 6 weeks after lower extremity free flap reconstruction is non-inferior after uncontrolled exposure compared to gradually increased venous pressure exposure; (2) there is a difference in length of hospital stay and major or minor adverse events 3 months after surgery.

Mental health is strongly associated with capability after lower extremity injury treated with free flap limb salvage or amputation.

Background: Knowledge about factors associated with long-term outcomes, after severe traumatic injury to the lower extremity, can aid with the difficult decision whether to salvage or amputate the leg and improve outcome. We therefore studied factors independently associated with capability at a minimum of 1 year after amputation or free flap limb salvage.

Methods: We included 135 subjects with a free flap lower extremity reconstruction and 41 subjects with amputation, between 1991 and 2021 at two urban-level 1 trauma centers with a mean follow-up of 11 ± 7 years.

Neuropathic Donor-Site Pain following Radial Forearm Free Flap Harvest: A Multicenter Study on Incidence, Prognostic Factors, and Quality of Life.

Background:  The radial forearm free flap (RFFF) is widely used and is considered one of the workhorse flaps in oncologic head and neck reconstructions. However, the potential for significant donor-site morbidity remains a major drawback. Although various donor-site problems have been reported, the incidence of neuropathic pain and possible predicting factors remain unclear.

Is dangling of the lower leg after a free flap reconstruction necessary? Study protocol for a large multicenter randomized controlled study.

Background: Within the field of plastic surgery, free tissue transfer is common practice for knee and lower leg defects. Usually, after such free flap reconstruction, patients undergo a dangling protocol in the postoperative phase. A dangling protocol is designed to gradually subject the free flap to increased venous pressure resulting from gravitational forces.

Subphenotyping and Classification of Cleft Lip and Alveolus in Adult Unoperated Patients: A New Embryological Approach.

Objective: Previously, a new embryological classification was introduced subdividing oral clefts into fusion and/or differentiation defects. This subdivision was used to classify all subphenotypes of cleft lip with or without alveolus (CL±A). Subsequently, it was investigated whether further morphological grading of incomplete CLs is clinically relevant, and which alveolar part is deficient in fusion/differentiation defects.
