Objective : Combined hyperative dysfunction syndrome (HDS) defined as the combination of HDSs such as trigeminal neuralgia (TN). hemifacial spasm (HFS) and glossopharyngeal neuralgia (GPN), which mayor may not occur simultaneously on one or both sides. We reviewed patients with combined HDS and demonstrated their demographic characteristics by comparing them with those of patients with a single HDS. Methods : Between October 1994 and February 2006, we retrospectively studied a series of 1,720 patients who suffered from HDS and found 51 patients with combined HDSs. We analyzed several independent variables in order to evaluate the prevalence and etiologic factors of combined HDS. Results : The combined HDS group accounted for 51 of 1,720 (2.97%) patients with HDS; 27 cases of bilateral HFS, 10 cases of bilateral TN and 14 cases of HFS with TN. Their mean age was 52.1 years (range, 26-79 years). There were 5 men and 46 women. Seven patients had synchronous and 44 patients metachronous onset of HDSs. By comparison of combined and single HDS groups, we found that age and hypertension were closely associated with the prevalence of combined HDS (p<0.05). Conclusion : This study revealed that combined HDS was very rare. Hypertension and age might be the most important causative factors to evoke combined HDS.

Elongation of the styloid process (styloid syndrome, Eagle's Syndrome) is named after Eagle who insisted the styloid process as a cause of pain but distinguishable from the glossopharyngeal neuralgia. Eagle's syndrome is characterized by a dull nagging pharyngeal pain, a palpable hardness in the tonsillar fossa, radiopaque elongation and enlargement of the syloid process. This is to report two cases of Eagle's Syndrome. The clinical and radiological features, development and pathogenesis of the Eagle's Syndrome and pathologic findings of the calcified styloid ligaments were described with review of literatures. The external cervical approach to resect the enlarged calcified processes can be an option due to better visualization and accessbility, less infection at risk than intra-oral approach. The findings and results were as follows ; 1. The calcified styloid ligaments accompanied with throat pain were reseded in size of $5.5{\times}48mm(#1,\;Rt)$, $3.6{\times}5mm(#1,\;Lt)$, $5.2{\times}51mm(#2,\;Rt)$ and $3.1{\times}38mm(#2,\;Lt)$. 2. The submandibular approach to resect the calcified styloid process is of help to get better visibility and accessiblilty avoiding the injury to the deep cervial vital structures. 3. The resected styloid processes were examined histopathologically as the matured cortical bones with marrow structures or cartilagenous cells without any findings of neoplasmic changes. 4. The remained process did not show any noticeable regrowth in 3 years after surgical amputation.
