Summary
Maxillary sinus fungus balls often show irregular CT findings. Surgical approach and outcomes depend on sinus pneumatization, influencing the extent of inferior meatal antrostomy (IMA) needed.
Area of Science:
- Radiology
- Otolaryngology
- Medical Imaging
Background:
- Maxillary sinus fungus balls are common conditions.
- Accurate classification of radiological findings is crucial for treatment planning.
Purpose of the Study:
- To classify radiological findings in patients with maxillary sinus fungus balls.
- To analyze surgical approaches and postoperative results based on these findings.
Main Methods:
- Retrospective study of 221 patients with maxillary sinus fungus balls.
- Analysis of computed tomography (CT) findings and surgical techniques.
Main Results:
- 49% of lesions on CT had irregular surfaces or protruding parts.
- Surgical approach differed significantly based on maxillary sinus pneumatization (p=0.042).
- Lesion extension was not associated with middle meatal antrostomy (MMA) stenosis (p=0.328).
Conclusions:
- Irregular lesion surface or calcification on CT suggests maxillary sinus fungus.
- Greater maxillary sinus pneumatization correlates with the need for more extensive inferior meatal antrostomy (IMA).

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

01:29Fungal Group Zygomycota
Zygomycota, previously classified as a distinct fungal group, are primarily terrestrial, saprophytic molds that play a crucial role as decomposers. Recent phylogenetic studies have revealed that these fungi are now divided into two major clades — Mucoromycota, which includes many symbiotic species, and Zoopagomycota, which primarily consists of parasitic and pathogenic fungi. These groups exhibit distinct ecological roles and reproductive strategies while sharing key structural and...

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...
