Summary
The palatal process pneumatization (PTP) type influences adjacent bone height. Type I PTP is associated with greater alveolar ridge height and palatonasal recess angle, crucial for maxillary sinus surgery.
Area of Science:
- Anatomy
- Radiology
- Oral and Maxillofacial Surgery
Background:
- Understanding maxillary sinus (MS) anatomy is vital for successful surgical outcomes.
- Cone beam computed tomography (CBCT) offers clear visualization of MS anatomy and pathology.
Purpose of the Study:
- To investigate the pneumatization types of the palatal process (PTP).
- To measure adjacent anatomical structures in relation to PTP types using CBCT.
Main Methods:
- Retrospective analysis of 400 maxillary sinuses from 200 patients.
- Classification of PTP into three types (I, II, III).
- Measurement of sinus and alveolar ridge height, palatonasal recess angle (PRA), and palatal junction angle (PJA) at specific distances from the incisive foramen.
Main Results:
- PTP Type I was the most frequent (25.3%), followed by Type II (23.8%) and Type III (1%).
- Patients with Type I PTP showed significantly higher alveolar ridge height and PRA at 4mm and 8mm compared to Types II and III.
- No significant differences were found between right and left sides for measured parameters.
Conclusions:
- PTP pneumatization patterns vary and correlate with adjacent bone dimensions.
- CBCT is a valuable tool for assessing MS anatomy and PTP variations.
- Knowledge of PTP types and associated measurements can aid in surgical planning for the maxillary sinus region.
