The implication of cervical pain associated with an elongated styloid process is credited to W.W.Eagle. Even though there were earlier reports of ossification of the stylohyoid ligament, findings in more than 200 cases in 1980s and 1940s resulted in the naming of a clinical syndrome that continues to bear his name, Eagle's syndrome. It is also sometimes called styloid process neuralgia or elongated styloid process syndrome is more common than generally recognized. The clinical symptoms range from a dull nagging pain with occasional radiation to ear, or to a foreign body sensation. Dysphagia and odynophagia may also occur. We successfully treated one case by removal of the elongated styloid process under the general anesthesia and C2 ganglion block. We then reported the clinical feature of one case of the Eagle's syndrome and further researched with the foreign literature.

Purpose : To find statistically based information about the natural variation in the length of the styloid process and to show the influence of the gender and age on the length of the styloid process. Materials and Methods : 1,300 panoramic radiographs were retrieved from inactive files at the Dental Hospital of Kyung Hee University. Measurements of the length of the styloid process were made directly on the radiographs from the inferior margin of the tympanic plate to the tip of the styloid process. Results The mean length of 948 styloid processes was $25.2mm{\pm}6.6$. The median was 24.5 mm, and the interquartile range was 7 mm. The mean length was 25.7 mm for male and 24.6 mm for female. All percentile was greater for male than for female. The median is 25 mm for male and 24 mm for female. Conclusion : This study suggests that the difference of the styloid process length between genders was statistically significant and the length of styloid process was significant increased with age until 30 years.

Objectives: This study was carried out to analyse Hand Greater Yang Skin in human. Methods: Hand Greater Yang meridian was labeled with latex in the body surface of the cadaver. And subsequently body among superficial fascia and muscular layer were dissected in order to observe internal structures. Results : A depth of Skin encompasses a common integument and a immediately below superficial fascia, this study established Skin boundary with adjacent structures such as relative muscle, tendon as compass. The Skin area of the Hand Greater Yang in human are as follows: The skin close to 0.1chon ulnad of $5^{th}$ nail angle, ulnad base of $5^{th}$ phalanx, ulnad head of $5^{th}$ metacapus(relevant muscle: abductor digiti minimi muscle), ulnad of hamate, tip of ulnar styloid process(extensor carpi ulnaris tendon), radiad of ulnar styloid process, 2cm below midpoint between Sohae and Yanggok(extensor carpi ulnaris), between medial epicondyle of humerus and olecranon of ulnar(ulnar nerve), The skin close to deltoid muscle, trapezius muscle, platysma muscle, inner muscles such as teres major muscle, infraspinatus muscle, supraspinatus muscle, levator scapulae muscle, splenius cervicis muscle, splenius capitis muscle, sternocleidomastoid muscle, digastric muscle, stylohyoid muscle, zygomaticus major muscle, auricularis anterior muscle. Conclusions: The Skin area of the Hand Greater Yang from the anatomical viewpoint seems to be the skin area outside the superficial fascia or muscles involved in the pathway of Hand Greater Yang meridian, collateral meridian, meridian muscle, with the condition that we consider adjacent skins.

Eagle syndrome is relatively uncommon with an incidence of abnormal stylohyoid length being 4% to 7.3%. A vast majority of individuals with elongation of the styloid process are asymptomatic. It is a syndrome marked by the clinical signs and symptoms of facial pain, ear pain, throat pain, dysphagia and a globus sensation in the throat. The cause of Eagle syndrome is believed to be a congenital or hormonal change and reactive osseus hyperplasia of the styloid process in response to pharyngeal trauma or surgical intervention, such as tonsillectomy. We present here a case of a 37-year-old female with a twelve-month history of both sided oropharyngeal pain and globus sensation which has no trauma or surgical intervention. The patient presented with a long, slender, bony intraoral projection that was found to be an elongated styloid process. We removed this elongated styloid process with a CO₂ laser, and her symptoms disappeared.

Eagle's syndrome occurs when an elongated styloid process or calcified stylohyoid ligament causes recurrent throat pain or foreign body sensation, dysphagia. It is supposed that this symptoms and signs are due to the compression of the styloid process on some neural and vascular structures. More uncommonly, symptoms such as dysphagia, tinnitus, and otalgia may occur in patients with this syndrome. It may also cause stroke due to the compression of carotid arteries. The compression depends on the size, shape, and orientation of the ossified styloid process Besides, degenerative or inflammatory changes in the tendinous portion of the styloid ligament insertion or rheumatic styloiditis may also cause this syndrome. Diagnosis can usually be made on physical examination by digital palpation of the styloid process in the tonsiller fossa. Three-dimensional computed tomography can utilized for supporting diagnosis. The treatment of Eagle's syndrome is primarily surgical. The styloid process can be shortened through an intraoral and extraoral approach. We report a 62-years-old man with the symptomatology of Eagle's syndrome and literature reviews.

A thirty two year-old male was referred with a chief complaint of mouth opening limitation, and maxillofacial pain including left TMJ area. The patient had been treated in a private clinic with medications and conservative treatments, without any improvements in symptoms. MRI findings showed a limitations in condylar head movements, and signs of disc adhesion without the Positional change. Panoramic views showed elongation of stylohyoid process. Brain C-T was taken due to the patient's complaint of headache, facial pain, and paresthesia of tongue, and the result showed no abnormalities. The first surgery included meniscoplasty and the removal of disc adhesion of left TMJ under the preliminary diagnosis of internal derangement with adhesion, and the patient displayed marked improvements in opening movements despite of persistent hemiparesthesia of left facial areas and tongue, and mild dysphasia. Therefore, the second surgery was carried out with the preliminary diagnosis of Eagle's Syndrome, and a resolution of neurologic symptoms was obtained. The final diagnosis of this case was Eagle's Syndrome with internal derangement, and the difficulties in diagnosis and treatment might be due to the existence of two separate diseases with similar symptoms.

Background: Temporomandibular joint (TMJ) ankylosis during early childhood may lead to disturbances in growth and facial asymmetry and to serious difficulties in eating as well as in breathing during sleep. The purpose of this study is to describe the effectiveness of an interocclusal splint (IOS) for active mouth opening exercises in the treatment of TMJ ankylosis. Methods: A total of nine patients with 13 instances of TMJ ankylosis from 2008 to 2010 were included in this study, of which five patients were male and four patients were female. Five patients demonstrated unilateral ankylosis, while five patients showed bilateral symptoms. Ankylosed mass resection with coronoidectomy, fibrotic scar release, and resection of stylohyoid ligament calcification was performed with gap arthroplasty without an interpositional graft, and all patients were assessed for maximum mouth opening (MMO) during a mean 6.6-year follow-up period. Results: All patients were subjected to postoperative mouth opening exercises from the day of the operation with the help of an IOS, which was based on an impression taken during surgery. All patients were sufficiently comfortable moving their mandible according to the IOS's guiding plane and impingement, and satisfactory results were achieved, in which MMO was improved by 35 mm more than 6 years after surgery. Conclusions: Complete and adequate resection of the ankylosed mass and postoperative active mouth opening exercises are essential in the treatment of TMJ ankylosis. Moreover, a more comfortable mouth opening guide and interdigitation can be achieved using an IOS, and newly organized fibrosis in the gap space between the newly made resected condylar head and temporal fossa can be suggested.

Eagle's syndrome refers to a symptomatic elongation of the styloid process or calcification of the stylohyoid and stylomandibular ligaments that usually accompanies facial and pharyngeal pain, dysphagia, and foreign-body sensation in the throat. Making an accurate diagnosis is difficult as Eagle's syndrome can be accompanied with referred pain to various areas of head and neck. Treatment options for Eagle's syndrome include non-surgical and surgical methods. The surest and the most effective method for relieving the symptom is surgical removal or reduction of the elongated styloid process. The present study reports two cases of female whom were diagnosed as "Eagle's syndrome" and whose chief complain was foreign-body sensation and pain in the throat on movement. Surgical removal via transoral approach of the elongated styloid process is a safe surgical option with favorable results compared to extraoral approach.
