[Clinical anatomy of the inferior wall of the orbit and its neighboring structures].

The development and size of the maxillary sinus, its septums and its cstium are measured. The nasolacrimal canal and duct and the foramina alveolaria superior are included. The thickness of the orbit floor (roof of maxillary sinus) is estimated. The angles of the inferior, medial, lateral rectus muscles, and the inferior oblique muscle with the median plane are determined. The results are discussed with those of earlier researchers. The clinical importance of the results are discussed.
