The maxillo-septal syndrome and temporomandibular joint dysfunction.

The results of twenty patients treated for the maxillo-septal syndrome and associated temporomandibular joint dysfunction are reported as well as the method of treatment. The treatment plan included rapid maxillary expansion with either a fixed or removable appliance, retention of the increased maxillary width with a Hawley retainer, simultaneous increase in mandibular width with a Crozat appliance. Finally the occlusion was equilibrated. Certain cases are discussed in detail and maxillary expansion was usually restricted to between 1 . 0 and 2 . 0 mm.
