1Oral and Maxillofacial Surgery Training Program, Foundation of Dentistry - Fundecto, University of São Paulo, São Paulo, Brazil.
Summary
Self-citation in Maxillofacial Surgery (MFS) literature is common, at 46.94%. This study found low correlations between self-citation and key bibliometric indicators, suggesting a nuanced impact.
Area of Science:
- Bibliometrics
- Scholarly communication analysis
- Maxillofacial Surgery (MFS) research impact
Background:
- Bibliometric analysis is increasingly used to assess academic impact.
- Self-citation is a common practice in scholarly publishing.
- Understanding self-citation's role in Maxillofacial Surgery (MFS) is crucial for accurate impact assessment.
Purpose of the Study:
- To perform a bibliometric analysis of self-citation within the Maxillofacial Surgery (MFS) literature.
- To evaluate the impact of self-citation on bibliometric indicators like the H-index.
- To provide a balanced perspective on self-citation in MFS research.
Main Methods:
- Retrospective bibliometric analysis adhering to Leiden Manifesto principles.
- Utilized Web of Science and Scopus databases for data retrieval.
- Analyzed 70,288 articles to identify prolific authors and assess self-citation rates.
Main Results:
- Identified 200 prolific authors from 25 countries in MFS literature.
- The self-citation rate in MFS was found to be 46.94%.
- Low correlations were observed between self-citation frequency and changes in H-index, exclusive MFS articles, and total publications.
Conclusions:
- Self-citation in MFS literature has a nuanced impact on bibliometric indicators.
- Avoid demonizing self-citation; a balanced, individual perspective is necessary.
- Self-citation may be linked to high productivity, expertise, and the dynamics of emerging research fields in MFS.

01:22Sutures of the Skull
6.3K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

01:14Cranial Bones: Superior and Posterior View
2.0K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:27Cranial Bones: Lateral View
2.0K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

1.1K
The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

01:16Bones of the Lower Limb: Femur and Patella
2.2K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

37.6K
The chi-square test is a statistical hypothesis test. It is used to check whether there is a significant difference between an expected value and an observed value. In the context of genetics, it enables us to either accept or reject a hypothesis, based on how much the observed values deviate from the expected values.
The chi-square test was developed by Pearson in 1990.
The first step of performing a Chi-square analysis is to establish a null hypothesis, which assumes that there is no real...
