Radiographic evaluation of the superior alveolar canal: measurements of its diameter and of its position in relation to the maxillary sinus floor: a cone beam computerized tomography study

Abstract

In the majority of our cases, the canal could be identified in at least one position, between the most posterior and the most anterior borders of the maxillary sinus. The large variation on the distance of the canal from the sinus floor dictates an individual evaluation of its position and not the use of mean values. Great care must be exercised by the radiologist to reliably identify the canal.

The potential clinical relevance of anatomical structures and variations of the maxillary sinus for planned sinus floor elevation procedures: A retrospective cone beam computed tomography study

“…The rate of PSAA canal detection using CBCT in the present research was 87.7%, which was compatible with previous studies . The fact that half (52.6%) of the PSAA canals in our study were intraosseous demonstrates that CBCT scans can be of significant benefit to the surgeon in predicting potential hemorrhage during antrostomy.…”

Anatomical Considerations on the Alveolar Antral Artery as Related to the Sinus Augmentation Surgical Procedure

“…(Tables and .) The lowest distances found are 2.80 mm from the alveolar crest and 0.00 mm from the sinus floor …”

“…Only 11 studies out of 18 report measurements regarding the diameter of the PSAA (Table ), 16 studies show data regarding the distance of the mentioned vessel from the alveolar crest (Table ), and only seven studies from the sinus floor (Table ). All the studies that give data for the distance from PSAA to sinus floor report also data for the distance from the alveolar crest at the same time, except one …”

Radiographic Evaluation of Maxillary Sinus Lateral Wall and Posterior Superior Alveolar Artery Anatomy: A Cone‐Beam Computed Tomographic Study

“…However, Yang et al showed that lateral wall thickness decreases from the M2 to the P1 region . The difference in the thickness of the lateral wall in different areas may be related to the position of the adjacent structures such as the buttress of the zygoma, maxillary tuberosity, and the canine eminence . Therefore, clinicians should consider these anatomic landmarks during the surgery.…”

“…Understanding the vascular anatomy of the maxillary sinus is also critical to avoid hemorrhage and membrane perforation (Figure ). Blood vessels with large diameters may impose more serious risk of bleeding during the surgery …”
