Summary
Cone beam computed tomography (CBCT) revealed maxillary sinus pathologies in 45.8% of sinuses, with mucous retention cysts and polypoidal thickening being most common. Understanding these pathologies and anatomical variations aids in reducing surgical complications.
Area of Science:
- Dentistry
- Radiology
- Otolaryngology
Background:
- Maxillary sinus pathologies are common and can impact dental and surgical procedures.
- Cone beam computed tomography (CBCT) is a valuable tool for visualizing the maxillary sinuses.
Purpose of the Study:
- To determine the frequency of maxillary sinus pathologies.
- To investigate the relationship between pathologies and anatomical variations.
- To propose a grading system for pathologies based on affected sinus walls.
Main Methods:
- Retrospective analysis of 1000 maxillary sinuses from 500 patients using CBCT.
- Evaluation for mucosal thickening, opacification, cysts, and polyps.
- Classification of pathologies based on the number of affected sinus walls.
Main Results:
- 45.8% of maxillary sinuses exhibited pathologies; 54.2% were normal.
- Mucous retention cyst (12.3%) and polypoidal thickening (12.2%) were the most prevalent pathologies.
- Pneumatization, ostium obstruction, and sinus-related roots were associated with pathology; nasal septum deviation and septa were not.
Conclusions:
- CBCT is effective for identifying maxillary sinus pathologies and anatomical variations.
- Pre-operative assessment with CBCT can help mitigate surgical complications like implant failure and oroantral fistulas.
- A new grading system based on affected walls can aid in understanding pathology extent.
