Endoscopically monitored maxillary sinus augmentation - The chairside approach (Rationale and protocol).

Sinus augmentation procedures have been reported since the time of Boyne, with variable techniques and outcomes. Sinus membrane perforations may or may not be detected at the intra-operative stage, thereby compromising the outcome. The aim of this study is to evaluate the usefulness and feasibility of an endoscope used intraorally during manipulation of the schnederian membrane. This would help confirm sinus health and integrity of the membrane during and after the augmentation.
