Transposition of the hemimasseteric muscle for dynamic rehabilitation of facial paralysis

The Journal of Craniofacial Surgery

Abstract

The masseter muscle is one of the muscles involved in mastication. Transposition of this muscle has been used for dynamic reanimation of facial palsy since the early years of the 20th century. We present an anatomic study of the masseter muscle and its neurovascular bundle to determine the possibility of using hemimasseteric transposition of the muscle for the rehabilitation of facial paralysis. Six white fresh cadavers were used to study the masseter nerve and the vascular supply to the masseteric muscle. Dissection was performed in each hemiface of each specimen. All the masseter nerve bundles were dissected to study their distribution. ANATOMIC STUDY: A constant anatomy was examined in all the specimens dissected. Dissection was performed inside the muscle body to expose the whole masseter nerve and its branches. A tree-like design of the nerve branches was observed. Each nerve branch was accompanied by its corresponding vascular pedicle, which guaranteed the vascular supply to the muscle divisions. The knowledge of the anatomy of the masseter nerve and its vascular supply is the key to preventing nerve damage when the muscle is split for facial reanimation. The possibility of selecting the bundle included in the transposed ...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
