title: [Upper and medial alveolar nerves. Study of their frequency and point of origin in 100 cases].
abstract: The existence, frequency and origin of the middle superior alveolar nerves was studied in 100 cases. 40 dried bones and 40 formaldehyded bones with the nerves in situ, were observed by transilumunation; and 20 hemi sectioned heads were disected with the help of transilumination. The middle superior alveolar nerve was found in 57 cases, in 35 arose from the Maxillary nerve trunk in the infraorbital canal and in 22 arose from the Maxillary nerve trunk in the tuberosity face of the maxillary bone, very near of the beginning of the infraorbital canal. A enlarged review of the literature and the comparison with our findings, was made too.
