Oral Synechia

Definition:

Objective: Fibrous band between the mucosal surfaces of the upper and lower alveolar ridges

Comments:

These bands must be distinguished from synechiae between the tongue and palate (glossopalatal ankylosis) and from synechiae arising from the floor of the mouth (as in the subglossopalatal membrane), oropharyngeal isthmus (as in persistent buccopharyngeal membrane) or from the lower lip [Gorlin et al., [2001]]. If there is a complete soft tissue contiguity between the upper and lower alveolar ridges, the term, Fibrous syngnathia should be used instead.
