Breast augmentation using a free lateral thoracic artery perforator flap from the contralateral breast: A case report.

Microsurgery 2021 Jun 4. Epub 2021 Jun 4.

Department of Plastic Surgery, Norfolk and Norwich University Hospital, Norwich, United Kingdom.

When performing breast reconstruction, reduction of the contralateral breast is often required to achieve symmetry. The tissue that would otherwise be discarded from the reduced breast has been utilized as a free flap. This has the benefit of minimizing donor site morbidity, and combining the principles of "spare-part-surgery" and replacing "like-with-like. Read More

Secondary Procedures after Severe Upper Extremity Injury.

J Hand Surg Asian Pac Vol 2021 Jun;26(2):152-157

Department of Hand and Reconstructive Microsurgery, National University Health System, Singapore.

Upper extremity trauma is one of the most common types of injuries, accounting for 20 to 40 percent of injured patients presenting to the emergency department. In severe upper extremity injury, the likelihood of secondary procedures to improve function and resolve outstanding clinical problems is high. Secondary procedures are performed later than initial primary surgery, usually after wound healing and with a discernible time gap of days, weeks or occasionally longer. Read More

Complex Microsurgical Reconstruction After Tumor Resection in the Trunk and Extremities.

Clin Plast Surg 2020 Oct;47(4):547-559

Division of Plastic and Reconstructive Surgery, Mayo Clinic, 200 First Street, Rochester, MN 55905, USA. Electronic address:

Reconstruction of soft tissue defects following tumor ablation procedures in the trunk and extremities can challenge the microsurgeon. The goal is not just to provide adequate soft tissue coverage but also to restore form and function and minimize donor site morbidity. Although the principles of the reconstructive ladder still apply in the trunk and extremities, free tissue transfer is used in many cases to optimally restore form and function. Read More

Intercostal Nerve Transfers to the Musculocutaneous-A Reliable Nerve Transfer for Restoration of Elbow Flexion in Birth-Related Brachial Plexus Injuries.

Indian J Plast Surg 2020 Aug 30;53(2):254-259. Epub 2020 Aug 30.

Department of Orthopaedic, Hand and Microsurgery, Assiut University, Assiut, Egypt.

 There is consensus on the need for early microsurgical reconstruction in birth palsies involving three or more roots, that is, extensive partial palsies and total palsies. The fundamental principles of these operations are complete exploration and judicious use of the ruptured stumps by nerve grafting to suitable distal targets. The frequent observation of root avulsions in such cases makes it imperative to look for extraplexual nerve donors for some functions. Read More

J Hand Surg Asian Pac Vol 2020 Sep;25(3):257-266

Department of Hand and Reconstructive Microsurgery, National University Hospital, Singapore.

The proximal interphalangeal joint (PIPJ) is a complex anatomical structure. In managing fracture dislocations about the PIPJ, the aim is to restore a congruent joint that allows for smooth gliding motion. Detailed knowledge of the anatomy and biomechanics of the PIPJ is necessary in managing these injuries with predictable success. Read More

Fracture dislocations of the carpometacarpal joints of the fingers.

J Clin Orthop Trauma 2020 Jul-Aug;11(4):562-569. Epub 2020 Jun 9.

Dept. of Plastic, Hand, Burns and Reconstructive Microsurgery, Ganga Hospital, Coimbatore, Tamilnadu, India.

Objective: Fracture dislocations of the multiple carpometacarpal joints [CMCJ] of the fingers are uncommon injuries that can significantly compromise hand function and durability if managed sub-optimally. These injuries are at risk of being missed as they are commonly a part of major high energy trauma with associated more obvious and immediately threatening injuries getting all the attention. The clinical and radiological parameters which could help a surgeon to detect and analyse these injuries well are discussed. Read More

Nat Protoc 2020 06 13;15(6):1992-2023. Epub 2020 May 13.

Department of Biomedical Engineering, University of Minnesota Twin Cities, Minneapolis, MN, USA.

Cranial microsurgery is an essential procedure for accessing the brain through the skull that can be used to introduce neural probes that measure and manipulate neural activity. Neuroscientists have typically used tools such as high-speed drills adapted from dentistry to perform these procedures. As the number of technologies available for neuroscientists has increased, the corresponding cranial microsurgery procedures to deploy them have become more complex. Read More

CHU Angers-Neurochirurgie, 4, rue Larrey, 49033 Angers cedex 3; Faculté de Médecine, Laboratoire d'Anatomie, Université Angers, rue Haute de Reculée, 49045 Angers, France.

Introduction: In France, microsurgery is taught in University diploma courses, for a mean 100hours (range, 45-120hours) extending over several months. This training, spread over the year, encounters problems of maintaining high-quality supervision and enduring acquisition of skills. These difficulties risk leading to withdrawal of certain courses, already suffering from funding issues and administrative requirements for animal welfare. Read More

Principles of Cortical Plasticity in Peripheral Nerve Surgery.

Surg Technol Int 2020 May;36:444-452

UOC Traumatology-Reconstructive Microsurgery, Department of Orthopedics and Traumatology, CTO Hospital, Torino, Italy.

Cortical plasticity is a finely regulated process that allows the central nervous system (CNS) to change in response to internal and external stimuli. While these modifications occur throughout normal brain development, interestingly, they are also elicited after peripheral nerve injury and surgery. This article provides an overview of the principle mechanisms of synaptic, neuronal, cortical and subcortical neuroplasticity, with special attention to cortical and subcortical modifications-as suggested by modern neuroimaging techniques-after peripheral nerve surgery.

Gaining Large Coverage With Small Island Pedicle Flaps in Tight Cosmetic Subunits: Taking Advantage of Rotation and Pincer Principles on the Nasal Ala.

J Cutan Med Surg 2020 Mar/Apr;24(2):154-160. Epub 2020 Feb 27.

8166 Department of Dermatology and Skin Science, University of British Columbia, Vancouver, Canada.

Background: Island pedicle flaps (IPFs) are widely used in reconstructive surgery due to their versatility, tissue efficiency, and excellent clinical outcomes. While IPF rotations and 'pincer flap' modifications have previously been sparsely described, they are not often discussed in the literature.

Objective: We demonstrate the use of both rotating IPFs and pincer techniques for defects traditionally considered too large for classic IPF design on the nasal ala. Read More

Can endoscopic ear surgery replace microscopic surgery in the treatment of acquired cholesteatoma? A contemporary review.

Int J Pediatr Otorhinolaryngol 2020 Apr 9;131:109872. Epub 2020 Jan 9.

Department of Otolaryngology Head and Neck Surgery, Ningbo Medical Center (Ningbo Lihuili Hospital), The Affiliated Lihuili Hospital of Ningbo University, Ningbo, Zhejiang, China; School of Medicine, Ningbo University, Ningbo, Zhejiang, China. Electronic address:

Acquired cholesteatoma leads to significant morbidities while current surgical options remain a challenge. The principles of surgery include complete removal of disease, prevention of recurrence, and restoration of hearing function when possible. Traditionally, this has been performed using microscopes; however, a novel technique using endoscopes offers a new perspective on our understanding of anatomy, pathogenesis and surgical approaches.

The Impact of Microsurgery on the Treatment of Ring Avulsion Injuries.

Plast Reconstr Surg 2019 12;144(6):1351-1357

From the Hansjörg Wyss Department of Plastic Surgery, New York University Langone Medical Center; the Section of Plastic Surgery, Dartmouth-Hitchcock Medical Center; and the Orlando Plastic Surgery Institute.

Background: Treating ring avulsion injuries continues to challenge the reconstructive hand surgeon. The complex operation draws from plastic surgery and orthopedic surgery principles to provide soft-tissue coverage, skeletal fixation, tendon repair, and neurovascular reconstruction. Furthermore, the application of microsurgical techniques has enabled the revascularization and replantation of completely avulsed fingers. Read More
