[The Akinosi dental anesthesia technique: apropos of 10 clinical cases]

The anesthesia technique described by AKINOSI in 1977, in Nigeria, shows certain advantages: According to the author, it has a percentage of efficacy, of about 95%. It permits an effective anesthesia of the inferior alveolar, lingual and buccal nerves to be obtained with a single injection. It has a psychological aspect which is of interest to the degree that it is carried out with the mouth closed, the patient thus being in a position of muscular and aponeurotic relaxation, which permits a nearly painless injection to be made. This technique has disadvantages which lead to a preference for the "Spix spinal" technique, each time that it is indicated; the onset is longer than the one at the Spix an average of 6 minutes (for all nerves) as seen in this study, but above all, it is a high vascular risk technic that can be conceived only if perfect knowledge of the pterygo-mandibular region has been gained so as to evaluate the vascular proximities, essentially the maxillary artery and the pterygoïd veinous plexas.
