Anterior maxillary wall and lacrimal duct relationship - CT analysis for prelacrimal access to the maxillary sinus.

CONCLUSION: Only in 12.5% of sinuses a prelacrimal endoscopic access is readily feasible, while in 56.5% temporary tear sac dislocation is required and in 31.5% lacrimal sac dislocation is always needed along with a significant amount of bone removal to enable PLWA.
