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.

Purpose: The Purpose of this study is to show the total survival rate of implants with maxillary sinus grafting and the effects that reach the survival rate by classifying types of graft materials, implant type, operation method, residual bone height and evaluate graft material resorption rate after sinus grafting Patients and Methods: 61 dental implants placed with sinus bone grafting in 24 patients at Wonkwang University Sanbon Dental Hospital were installed simultaneously or after regular healing. Various bone grafts (autograft, xenograft, allograft, alloplast) and fourth implant type (GSII, Xive, Implantium, Novel biocare) were used. All implants were investigated clinically and radiographically, being with average 20 months follow-up period after installation. Results: 3 fixtures were lost, resulting in 95.1% cumulative survival rate of 61 osseointegrated dental implant. Survival rate according to bone material type, Implant type, operation method, residual bone height, have no statistically significant differencies. The mean preoperative residual alveolar bone height was 4.75 mm, average postoperative height of graft materials 10.8 mm, vertical bone resorption rate was 10% after 2 years. Resorption rate according to operation method was 7% (simultaneous) and 5% (delayed) after 1 year. Conclusion: It can be suggested that maxillary sinus grafting may have predictable result with various bone graft materials and implant type, residual bone height, operation method

The purpose of this study is to investigate difference between manifest refraction (MR) and cycloplegic refraction (CR) with age and myopic value. Methods: Manifest and cycloplegic refractions were carried out on the patients of 229 myopic patients (25.3±11.9 years old). Results: The average results from a pre- and a postcycloplegic refraction showed a reduction of 0.19 D in myopia, 0.02 D in astigmatism and 1.85o in astigmatism direction. Change of myopic value was higher in 30~40 age. Total 73 eyes of 229 patients who showed 0.50 diopter (D) in spherical, and a high degree of myopia group showed a higher discrepancy rate. Conclusions: The results found in the comparison of the value of the manifest refraction and cycloplegic refractions showed changes of myopic value was not significant with age of patient, but the group of high degree of myopia showed higher discrepancy rate.
