ABSTRACT


Purpose: Evaluate The Prevalence Of Posterior Superior Alveolar Canal By Cone Beam Computed Tomography In A Sample Of Egyptian Population

Materials and Methods: CBCT Radiographs Of 600 Maxillary Sinuses Of 304 Males And 296 Females Patient With Mean Age Of 34.5 Years Were Examined For Presence Or Absence Of The Posterior Superior Alveolar Canal Along The Lateral Wall Of The Maxillary Sinus Among The Sample.

Results: The Posterior Superior Alveolar Canal Could Be Detected In 92% Of The Cases .

Conclusions: Cone-beam Computed Tomography Is Valuable Tool In Evaluation And Localization Of The Posterior Superior Alveolar Canal Before Maxillary Sinus Lift Surgery To Avoid Bleeding During Surgery.
