Keetly et al7 while discussing the possible reasons for failure of inferior alveolar nerve block identified by the participants as being unable to locate anatomical landmarks like pterygomandibular
raphe, inability to find a bony landmark with the needle, inability to direct the needle satisfactorily due to tough tissue in the pterygomandibular
space, large tongue unable to rest passively, difficult anatomy where posterior teeth have been lost and alveolar resorption has been excessive and needle curved due to excessive manipulation within the tissues.
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
The fibrotic bands in the buccal mucosa run in vertical directions, in the soft palate the fibrous bands radiate from the pterygomandibular
raphe or the anterior faucial pillars and in the lips circular bands can be felt around entire rima oris.
(1,3-25) From this search, we found that glomangiopericytomas have also been reported in cardiac muscle, (4,7) the pterygomandibular
space, (6) and the upper and lower limbs.
Complications related to IANB injection include transient facial paralysis, trismus, local anaesthetic injected into blood vessel, self-inflicted trauma, damage to sphenomandibular ligament and pterygomandibular
Based on this finding, inserting the needle 4 mm above the occlusion level of the molar is enough to go through the pterygomandibular
space without difficulty in order to perform the inferior alveolar nerve block.
Fibrotic bands are visible at the soft palate, and pterygomandibular
raphe and anterior tonsillar pillars.
Under general anesthesia and aseptic conditions the operative area was exposed through submandibular incision and the pterygomandibular
sling was incised.
Intraoral examination demonstrated an exophytic, fungating mass on the buccal mucosa, on the right hand side, extending antero-posteriorly from the right commissure to approximately 3 cm anterior to the pterygomandibular
The parapharyngeal space has also been referred to in the literature as the lateral pharyngeal, peripharyngeal, pharyngomaxillary, pterygopharyngeal, pterygomandibular
, and pharyngomasticatory space, and its boundaries have been described with more variation than those of any other space of the neck.
The pad was first described 300 years ago and was considered a nuisance by surgeons for many years because of its accidental encounter during various operations in the pterygomandibular
The region of the bone between the neck of the mandible and a hori-zontal line in the ramus of mandible just above the mandibular foramen was removed carefully to ex-pose the pterygomandibular
