Resumo
study was based on the hypothesis that a TMD can be the etiological
factor in ocular pain and to test it the authors performed a clinical evaluation in TMD
patients presenting with sphenomandibular muscle hyperactivity. The hypothesis is
based on the fact that the muscle originates in the lateral aspect of the orbit, with a
point of insertion in the mandible. It is an observational and descriptive study,
characterized by: 1) an anatomical investigation performed in cadavers and 2) a
clinical interpretation of the physiological relationship between sphenomandibular
muscle functions and symptoms involving temporomandibular disorders presenting
with ocular pain. Ten anatomical specimens (five cadavers) from the Anatomy
Department of the School of Medicine of the Catholic University of Goiás were
examined. One hundred three patients with temporomandibular disorders (TMD)
were treated and followed in the Outpatient Clinic of the School of Dentistry of the
Federal University of Goiás for the purpose of studying the interrelationship between
cervical and craniofacial pain symptoms and craniomandibular disorders. The work
was carried out in the Outpatient Clinic of the School of Dentistry of the Federal
University of Goiás, between April 2006 and December 2008. Inclusion criteria, used
to form Group I, totaling 58 patients, included temporomandibular disorders, referred
ocular pain and sphenomandibular muscle hyperactivity. Group II comprised 45
patients who did not present with sphenomandibular muscle hyperactivity. All the
patients received treatment for Temporomandibular Disorder (Groups I and II) and
were followed for two years, with biannual evaluation visits. Response to treatment
was evaluated by means of an opinion-based questionnaire that served to stratify the
level of ocular pain, which was reported as eliminated in 46 of the 58 patients in Group I (79.3%) and in eight Group II patients (17.8%). This evaluation has made it
possible for the authors to affirm that the sphenomandibular muscle is independent
from the temporal muscle and is closely related to the orbit; the clinical examinations
conducted along the study enabled the evaluation of sphenomandibular muscle
hyperactivity in temporomandibular disorder episodes; and this hyperactivity is
significantly associated to the presence of referred ocular pain.
