A METHOD OF COMPLEX EVALUATION OF MORPHOLOGICAL STRUCTURE OF OSTIOMEATAL COMPLEX COMPONENTS, LOWER WALL OF MAXILLARY...

Area of Science:

• Anatomy
• Radiology
• Otolaryngology

Background:

• Paranasal sinus (PNS) inflammatory processes, including odontogenic maxillary sinusitis, are common clinical issues.
• Understanding anatomical variability is crucial for diagnosing and managing sinus pathologies.
• The ostiomeatal complex (OMC) plays a key role in sinus drainage and ventilation.

Purpose of the Study:

• To evaluate anatomical variations of the frontal and maxillary sinuses and OMC components.
• To identify factors contributing to inflammatory complications and odontogenic maxillary sinusitis.

Main Methods:

• Assessment of 100 spiral computed tomograms (SCT) from patients without sinonasal pathology.
• Determination of anatomical parameters of the OMC (hooked process, middle nasal conch, natural ostium).
• Measurement of maxillary and frontal sinus lower wall thickness and density using uncertainty calculation.

Main Results:

• Detailed bone density values for the maxillary and frontal sinuses were recorded.
• Probable OMC structure parameters were calculated with a confidence level of p = 0.95.
• Specific anatomical measurements and density variations were quantified.

Conclusions:

• Certain anatomical variants of the OMC can predispose to paranasal sinus hypoventilation and inflammation.
• Structural features of the paranasal sinus walls can facilitate the spread of inflammation and complications.
• Anatomical assessment is vital for predicting and preventing sinus inflammatory conditions.
