PURPOSE: A survey was performed to identify the level of mouthguard use, awareness, wearability issues and attitude toward mouthguard among elite Korean Taewondo athletes. MATERIALS AND METHODS: Survey questionnaires were given to 152 athletes participating in the Korea National Taekwondo team selection event for the 2010 Guangzhou Asian Games. Questionnaires consisted of three sections, mouthguard awareness, reasons for not wearing mouthguard and the last section to test the level of acceptance on current mouthguard and when the identified problems were resolved. For analyzing difference among response, chi2 test was used and significant level (alpha) was set up as 0.05. RESULTS: Responses in each of items showed significant difference (P<.001). Majority of response regarding each question: Majority of respondents believed that mouthguard were effective in preventing injuries (36.4%) but the result suggested that the provision of information on mouthguard to athletes was inadequate (44.0%) and the result showed that respondents were not greatly interested or concerned in relation to the mandatory mouthguard rule (31.6%). Although the responses on the level of comfort and wearability of mouthguard were negative (34.8%), athletes were positively willing to wear mouthguard if the problems rectified (51.2%). CONCLUSION: Considering the high level of willingness to wear mouthguard if the problems rectified, it is thought that together with efforts in providing more mouthguard information, the work of sports dentistry to research and improve mouthguard will be invaluable in promoting mouthguard to more athletes.

Ictal spitting is an unusual manifestation that originates from the non-dominant hemisphere, but rarely from the dominant hemisphere. In the latter case, it has not been well defined as to whether symptomatogenic area for ictal spitting originates from the dominant hemisphere. We present a patient with ictal spitting. Intracranial EEG demonstrated a left hippocampal onset with propagation to the right hemisphere, and subsequent ictal spitting development. Even in dominant hemispheric seizures, the non-dominant hemisphere is a symptomatogenic area for ictal spitting.

BACKGROUND AND OBJECTIVES: Most cases of epistaxis can be controlled by conservative management such electrocautery or nasal packing. However, for some cases of the posterior epistaxis, invasive procedures like endoscopic sphenopalatine artery ligation (SPAL) or arterial embolization are needed. In this study, risk factors present in patients who were hospitalized due to posterior epistaxis and postoperative complications and causes of recurrence after SPAL were analyzed. SUBJECTS AND METHOD: A retrospective chart review of 75 patients who were admitted to Gyeongsang National University Hospital for the treatment of posterior epistaxis between 2009 and 2014 was performed. Demographic factors, seasonal variation, comorbid diseases, and laboratory results were analyzed. Furthermore, 35 patients who have undergone SPAL were surveyed by telephone regarding postoperative complications, and preoperative computerized tomography (CT) images were reviewed to figure out the causes of the recurrence after SPAL. RESULTS: Among 75 patients, 53 (70.7%) were males. Male preponderance (80%) was more definite among those who have undergone SPAL (p=0.04). Age over 40 as well as the winter season and the underlying disease such as hypertension were also critical risk factors for posterior epistaxis. Four out of 35 patients who had undergone SPAL showed recurrence. The bleeding was detected in the branches of sphenopalatine artery in three out of the four patients who experienced recurrent bleeding following SPAL, which were controlled by revision surgery or arterial embolization. CONCLUSION: Posterior epistaxis occurred frequently in men over 40 years of age and in winter. A careful preoperative review of CT images and meticulous dissection during SPAL might be helpful for preventing recurrence after SPAL.
