Atomic Orbitals

43.3K
An atomic orbital represents the three-dimensional regions in an atom where an electron has the highest probability to reside. The radial distribution function indicates the total probability of finding an electron within the thin shell at a distance r from the nucleus. The atomic orbitals have distinct shapes which are determined by l, the angular momentum quantum number. The orbitals are often drawn with a boundary surface, enclosing densest regions of the cloud.

Electron Orbital Model

71.8K
Orbitals are the areas outside of the atomic nucleus where electrons are most likely to reside. They are characterized by different energy levels, shapes, and three-dimensional orientations. The location of electrons is described most generally by a shell or principal energy level, then by a subshell within each shell, and finally, by individual orbitals found within the subshells.
The first shell is closest to the nucleus, and it has only one subshell with a single spherical orbital called the...

Hybridization of Atomic Orbitals I

66.0K
The mathematical expression known as the wave function, ψ, contains information about each orbital and the wavelike properties of electrons in an isolated atom. When atoms are bound together in a molecule, the wave functions combine to produce new mathematical descriptions that have different shapes. This process of combining the wave functions for atomic orbitals is called hybridization and is mathematically accomplished by the linear combination of atomic orbitals. The new orbitals that...

Area of Science:

  • Ophthalmology
  • Neurosurgery
  • Plastic Surgery

Background:

  • Proptosis, or bulging eyes, can result from various non-thyroidal conditions.
  • Surgical orbital decompression aims to reduce intraorbital pressure and improve ocular protrusion.

Purpose of the Study:

  • To evaluate the safety and efficacy of orbital decompression for non-thyroid eye disease-related proptosis.
  • To analyze proptosis reduction across different etiologies of non-thyroid eye disease.

Main Methods:

  • A multicenter retrospective chart review of 41 orbits from 29 patients undergoing orbital decompression.
  • Patients were categorized into negative vector, inflammatory, and tumor groups.
  • Hertel exophthalmometry was used to measure proptosis reduction, with a minimum 6-month follow-up.

Main Results:

  • Mean proptosis reduction was 2.95 mm (negative vector), 2.54 mm (inflammatory), and 5.75 mm (tumor).
  • No serious complications were reported during the study period.
  • The tumor group exhibited the most significant reduction in proptosis.

Conclusions:

  • Orbital decompression is a safe and effective treatment for reducing proptosis in non-thyroid eye diseases.
  • Proptosis reduction varied by etiology, with inflammatory conditions showing less improvement compared to others.
  • Orbital decompression offers a viable option for managing proptosis in diverse non-thyroidal orbital conditions.
