It must be highlighted that the anterior superior alveolar nerve
(ASAN) is one of the branches originated from the infraorbital nerve before entering the homologous foramen (Joo et al., 2014).
PSANB- posterior superior alveolar nerve
block is such a kind of nerve block in maxilla.
While the ION is in the canal, it provides sensory innervations to the maxillary anterior teeth (anterior superior alveolar nerve
), premolars (middle superior alveolar nerve
), and associated gingiva.
Canalis sinuosus is a neurovascular canal, nerve branch of the infraorbital canal, that passes the anterior superior alveolar nerve
, initially described by Jones in 1939 and on occasion by Gray , being a little-known structure, with few cases described in the literature.
Infratemporal space infection can be observed after maxillary molar infections, a posterior superior alveolar nerve
or inferior alveolar nerve blocks as well as mandibular third molar infections that spread to pterygomandibular space (15).
(6) Alternately, the superior alveolar nerve
could have been damaged during the tooth extraction; however, if this were the case, one would suspect a sensory deficit, and there was no discernible sensory deficit in this patient.
Using aseptic technique local anesthesia (Posterior superior alveolar nerve
block and infiltration) was given.
The anterior superior alveolar nerve
block is used to obtain anesthesia of the maxillary canine and central and lateral incisors.
These denervated upper anterior teeth is due to the damage to the anterior superior alveolar nerve
when removing bone from the canine fossa region.
