Transposition Island Pedicle Flap to Repair the Nasal Ala.
Cureus
August 2024
Medicine, William Carey University College of Osteopathic Medicine, Hattiesburg, USA.
Article Synopsis
- Reconstruction of the nasal ala poses challenges such as loss of the nasofacial junction and compromised blood supply, while aiming for good cosmetic results.
- A new surgical technique using a melolabial-based transposition island pedicle flap offers an effective alternative to traditional methods, allowing for a single-stage procedure.
- This flap technique, which involves careful dissection from the nasolabial fold, is particularly suitable for patients with specific nasal defects and results in minimal complications and a cosmetically pleasing outcome.
The effect of human recombinant epidermal growth factor on neovascularization and pedicle division time in a rat interpolation flap model.
Turk J Med Sci

Department of Pathology, Manisa Celal Bayar University, Manisa, Turkiye.
Article Synopsis
- The study investigated the impact of recombinant human epidermal growth factor (rhEGF) on the viability of skin flaps post-surgery, focusing on whether it could reduce healing issues related to the timing of flap pedicle division.
- Thirty-six rats were divided into control and study groups, with the latter receiving a single injection of EGF during the surgical procedure, and results showed that the study group had significantly less necrosis and improved healing metrics compared to the control group.
- Histopathological analysis indicated that EGF treatment enhanced granulation tissue and neovascularization, suggesting that it can promote better flap outcomes and potentially allow for earlier pedicle division in clinical settings.

Cutis
July 2023
Karissa Libson is from The Ohio State University College of Medicine, Columbus. Drs. Varra, Shahwan, and Carr are from the Department of Dermatology, The Ohio State University Medical Center, Columbus. Dr. Shahwan also is from Altru Health System, Grand Forks, North Dakota, and the University of North Dakota School of Medicine & Health Sciences, Grand Forks.
Article Synopsis
- Reconstruction of a large conchal bowl defect is difficult due to its complex shape and the need for strong structural support.
- Traditional methods involve multi-stage repairs, like using a pedicled flap from behind the ear.
- For significant cartilage loss but preserved skin, the retroauricular pull-through sandwich flap is recommended, which integrates a cartilage graft and a flap to cover the front of the ear.

Dermatology Department, Complejo Asistencial Universitario de León, León, Spain.
Article Synopsis
- The paramedian forehead flap allows for tissue transfer from the forehead to the nose and is usually divided after 14 to 21 days, but this study aims to show it can be done sooner.
- Researchers conducted a study with 12 patients needing nasal reconstruction, using ultrasound to measure the optimal division time for the flap.
- Results indicated that the average time to successfully divide the flap was about 6.9 days, with no major complications, suggesting that ultrasound is an effective and economical method to personalize the timing for flap division.

- - A systematic search identified 12 relevant studies, which reported complications and outcomes related to aesthetics and function following different surgical techniques.
- - Overall, while most flap techniques showed positive results, careful planning of donor sites is crucial for good cosmetic results, particularly with certain types of flaps, and there's a need for additional research.
Xenografts in the post-operative wound management of interpolation flaps.
J Cosmet Dermatol
January 2022
Cleveland Clinic Foundation, Fort Lauderdale, Ohio, USA.
Article Synopsis
- Safeguarding the donor site during the initial phase of an interpolation flap is challenging, with no widely accepted postoperative management practices; using xenografts can improve care by preventing infection and simplifying wound management.
- A study involved using a porcine acellular dermal skin substitute for four patients undergoing postauricular interpolation flaps, where the xenograft was sutured to aid in healing.
- The results showed no infections or bleeding issues, suggesting that this approach offers an effective alternative to traditional methods for managing donor sites.
