Maxillary sinus variations, including accessory ostia, are common (77.8%) and linked to age and gender. Understanding these anatomical differences is crucial for successful dental surgery.
Area of Science:
- Dentistry
- Radiology
- Anatomy
Background:
- The maxillary posterior region presents anatomical challenges due to its complex structure and variations.
- Complete anatomical knowledge is essential for dental procedures in this area.
- Cone-beam computed tomography (CBCT) offers reliable 3D evaluation for surgical planning.
Purpose of the Study:
- To determine the prevalence of maxillary sinus variations (septa, Haller cell, accessory ostium).
- To calculate average maxillary sinus diameters.
- To investigate relationships between variations, diameters, age, and gender.
Main Methods:
- Retrospective analysis of CBCT images from 212 patients.
- Morphometric analysis of maxillary sinus anatomy.
- Statistical evaluation using descriptive statistics, chi-square, t-tests, and ANOVA.
Main Results:
- A statistically significant difference was found in maxillary sinus morphometrics concerning variations, gender, and age.
- Accessory ostium was the most frequently observed variation.
- 77.8% of patients exhibited at least one anatomical variation.
Conclusions:
- Maxillary sinus variations are prevalent and influenced by demographic factors.
- Detailed pre-surgical analysis is vital to prevent complications.
- CBCT is instrumental in identifying these variations for improved surgical outcomes.

Cranial Bones: Lateral View
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...
Graphical and Analytic Representation of Sinusoids
The first step is measuring the peak-to-peak value, which is twice the amplitude of the sinusoid. This provides information about the maximum voltage swing of the waveform.
Secondly, the period and angular frequency are determined. The period is the time taken for one complete cycle of the waveform, while...
