Describe the features of the retromolar region?
In the retromolar region, in front of the pillars of fauces, a fold of mucosa containing the pteryogomandibular raphe extends from the upper to the lower alveolus.
The pterygomandibular space, in which the lingual and inferior alveolar nerves run, lies lateral to this fold and medial to a ridge produced by the mandibular ramus.
