Abstract

Therapeutic goals for orthognathic surgery are not only directed towards the correction of dento-osseous deformieties but also to provide the optimal functional and esthetic effect that results in patients satisfaction. THE AIM OF THE STUDY was to evaluate soft tissue changes following surgical treatment of patients with mandibular prognathism operated with two alternative techniques: extraoral vertical ramus osteotomy or sagittal split ramus osteotomy. A sample of 37 patients with mandibular prognathism operated in Cranio-Maxillofacial Department. The patients included in the study underwent isolated surgery within mandibular rami, without any adjunctive procedures. Long-term and early outcomes of soft tissue changes following surgery were monitored by means of cephalometric analysis according to Arnett in consecutive intervals: before surgical treatment; 1 to 2 weeks after surgery; 6 months and 12 months after surgery. Study variables included age, gender and method of surgical treatment. In both groups operated with bilateral sagittal osteotomy and extraoral vertical ramus osteotomy methods increase of A'-B' value in T2, T3 i T4 comparing values in T1 was recorded. Immediately and 12 months after both surgeries increase of U...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.
