Maxillary sinus mucocele with orbital complications
Annali Italiani Di Chirurgia
|April 18, 2018
Summary
Maxillary sinus mucoceles can cause eye problems like diplopia. Endoscopic sinus surgery effectively treats these mucoceles, restoring sinus and ocular function without bone reconstruction.
Area of Science:
- Otolaryngology
- Ophthalmology
Background:
- Maxillary sinus mucoceles are rare, often resulting from secondary causes like surgery or inflammation.
- They involve mucous secretion within the sinus, lined by respiratory epithelium.
Observation:
- A 74-year-old patient with a history of nasal surgery developed diplopia and eye discomfort.
- CT revealed a mucocele in the left maxillary sinus with orbital floor erosion.
- Isolated left inferior rectus palsy was noted on oculistic examination.
Findings:
- Endoscopic sinus surgery, including middle meatal antrostomy and mucocele removal, was performed.
- Post-operative follow-up showed a regular maxillary cavity and normal ocular motility.
- The study suggests bone reconstruction is unnecessary if maxillary mucosa integrity is maintained.
Implications:
- Endoscopic sinus surgery is an effective treatment for maxillary sinus mucoceles causing ocular symptoms.
- Antrostomy and drainage can restore both paranasal sinus and ocular function.
- Preserving maxillary upper wall mucosa integrity is key, potentially avoiding complex bone reconstruction.

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.

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...

In an atom, the negatively charged electrons are attracted to the positively charged nucleus. In a multielectron atom, electron-electron repulsions are also observed. The attractive and repulsive forces are dependent on the distance between the particles, as well as the sign and magnitude of the charges on the individual particles. When the charges on the particles are opposite, they attract each other. If both particles have the same charge, they repel each other.
