Microdissected thin anterolateral thigh perforator flaps with multiple perforators: A series of case reports

Thin and Thinned Anterolateral Thigh Flaps for Upper Extremity Reconstruction

Upper extremity reconstruction remains challenging due to the high functional and esthetic demands of this location. The anterolateral thigh (ALT) flap is a workhorse flap for microsurgical reconstruction of the upper extremity and can be elevated in various planes depending on desired thickness of the flap. Microsurgical reconstruction of the upper extremity often benefits from a thin flap that can resurface the extremity, which can provide improved functional and esthetic outcomes. This article reviews the anatomy, preoperative planning, and operative technique, as well as presents 4 cases to illustrate the outcomes and benefits of thin and thinned ALT flaps.

A split flap technique shifting the location of perforator entry point to lengthen the pedicle of a multiple perforator based free flap

BACKGROUND

Pedicle length deficiency in microsurgical procedure is a challenging issue. The aim of this report is to present a case series of a flap-splitting technique for pedicle lengthening of large multiple perforator-based (MPB) free flaps.

METHODS

In this retrospective case series, we reviewed the medical records of patients who underwent free flap repair with "split flap" pedicle-lengthening technique between August 2017 and December 2021. Main outcome measures included patient demographics, indications, defect size, flap type, additional vascular pedicle length, and flap survival.

RESULTS

Data from 16 patients (age 38-78 years) were reviewed. Indications included breast reconstruction, repair of scalp malignancy or titanium mesh implant exposure, and repair of burn scar contracture. Flaps included ALT flap, LD flap and DIEP flap. The mean added pedicle length was 3.8 cm. Fifteen flaps survived completely and one flap was necrotic distally. No major complications occurred.

CONCLUSIONS

The 'split flap' technique could be an effective remedy for unexpected pedicle length deficiencies in large MPB free flaps.

Acute Management of Thermal Hand Burns in Adults: A 10-Year Review of the Literature

INTRODUCTION

Advances in the evidence base of acute thermal hand burns help to guide the management of these common injuries. The aim of this literature review was to evaluate recent evidence in the field over 10 years.

METHODS

The Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols methodology was used as a guide for this literature review. PubMed, MEDLINE, EMBASE, CINAHL, and Google Scholar were searched for English language articles related to hand burns published between 2009 and 2018 inclusive, and the Cochrane Library was reviewed. Exclusion criteria were as follows: participants younger than 18 years, scar or contracture management, rehabilitation, outcomes assessment, late reconstruction, and electrical or chemical burns.

RESULTS

An initial search retrieved 6493 articles, which was narrowed to 403 full-text articles that were reviewed independently by 3 of the authors and categorized. Of 202 included articles, there were 8 randomized controlled trials and 2 systematic reviews. Six evidence-based guidelines were reviewed. Referral of hand burns to specialist centers, use of telemedicine, early excision and grafting, and immediate static splintage have been recommended. Enzymatic debridement results in earlier intervention, more accurate burn assessment, preservation of vital tissue, and fewer skin grafts, and ideally requires regional anesthesia. Guidance on escharotomy emphasizes indication, technique and adequate intervention, and potential for enzymatic debridement. Inclusion of topical negative pressure, dermal regenerative templates, acellular dermal matrices, and noncellular skin substitutes in management has helped improve scar and functional outcomes.

DISCUSSION

The results of this literature review demonstrate that multiple national and international societies have published burns guidelines during the decade studied, with aspects directly relevant to hand burns, including the International Society for Burn Injuries guidelines. There are opportunities for evidence-based quality improvement across the field of hand burns in many centers.

CONCLUSIONS

More than 200 articles globally in 10 years outline advances in the understanding of acute management of thermal hand burns. Incorporating the evidence base into practice may facilitate optimization of triage referral pathways and acute management for hand burns.
