Eagle's syndrome: treatment by intraoral bilateral resection of the ossified stylohyoid ligament. A review and report of two cases.

The complexities of Eagle's syndrome are examined according to anatomical, historical, clinical, and treatment aspects. There appears to be little correlation between the extent, form, and size of the anomalies of the styloid process and the stylohyoid ligament and the predictability of patients with related symptoms. Surgical treatment and the advantages and disadvantages of each surgical approach (intra- and extraoral) are discussed. The probable causes of enlargement of the styloid process and ossification of the stylohyoid ligament are addressed. Two cases of Eagle's syndrome are presented: one unilateral and the other bilateral. An intraoral modified surgical technique is presented.
