Article Synopsis
  • - The report evaluates a surgical technique for nasal reconstruction using auricular cartilage and skin grafts in a 50-year-old woman with severe nasal deformities following a car accident.
  • - The surgery resulted in a high survival rate of grafts and a successful aesthetic outcome, with the reconstructed nasal ala closely resembling the other side.
  • - Postoperative follow-ups indicated high patient satisfaction, suggesting that the procedure positively impacts quality of life and psychological well-being for individuals with complex nasal defects.

Reconstruction of functional human lips utilizing a prelaminated flap.

Front Bioeng Biotechnol

Emeritus in Surgery, University of Michigan, Ann Arbor, MI, United States.

Lips form a structure that are difficult to reconstruct after a traumatic avulsion injury or cancer ablative surgery secondary to loss of volumetric muscle mass. Traditional tissue engineering approaches of fabrication of mature tissue constructs can supply an alternative to the current surgical standard of care for functional lip reconstruction. We demonstrate a hybrid approach that combines the advantages of muscle flap prefabrication with fabrication of an autogenous mucocutaneous construct as the laminate for prelamination to form a designer microvascular muscle free flap for lip reconstruction.

The free fibular flap has been elevated by a "lateral approach" from the posterior edge of the peroneal muscle for more than 40 years. However, in this approach, the surgical view is limited because flap elevation in mandibular reconstruction is performed simultaneously with tumor resection in the supine position, even when using positioning pillows. We herein propose an "anterior approach" as a new surgical method.

Excessive compression after parotidectomy can lead to flap necrosis, while inadequate pressure can cause fluid accumulation. This study aimed to determine the optimal pressure and compression properties of different types of dressings. Initially, pressure measurements were taken for conventional Barton's dressing and a pre-fabricated facial garment.
