Reduction genioplasty for mandibular prognathism and long chin

Oral and Maxillofacial Surgery
Igor Niechajev

Abstract

When evaluating patients' profile, surgeons usually note the lack of the chin projection and may suggest chin augmentation, but they rarely discuss reduction of an over-projecting chin. This is unfortunate, since there are quite many individuals who have macrogenia and would aesthetically benefit from corrective surgery, but the chin reduction is seldom offered. The reason for this is the lack of experience, lack of the technical equipment necessary, or sometimes lack of knowledge. The present study conveys 25 years of experience with the reduction genioplasty. From 1994 to 2019, 47 patients (39 females, 6 males, and 2 male to female transsexuals) underwent 49 chin reduction procedures. All patients were operated and followed up by the author. The transoral approach was used in 23 patients, and in 24 patients the procedure was done through the straight 4- to 6-cm-long submental incision. The air-driven pneumatic chisel was employed for reduction of the mandibular bone (MicroAire, Charlottesville, VA, USA). Forty-eight operations were carried out under dissociative and local anaesthesia on an outpatient basis, and one procedure was done under general endotracheal anaesthesia. Both mandibular bone and the soft tissues of the chin...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.
