  • Objectives : This study was to investigate the use of mouth-guards and maxillofacial injuries and to examined the relationship among variables in athletes group. Methods : The subjects were 459(86.5%), who were 18 years or older with mean age of 20.7 years. Data was collected using a self administrated questionnaire from May 25 to June 15, 2009. We surveyed maxillofacial injuries(temporo-mandibular disorders contained) and mouth-guards usage and confidence concerning mouth-guards in athletes. The data were analysed with chi-square analysis, fisher's exact test and logistic regression using the SPSS 15.0 windows. Results : Prevalence of body or maxillofacial injuries experiences was 54.5% for athletes and 47.1% for non-athletes groups(p>0.05). The other hand, the incidence temporo-mandibular disorders was 67.0% for athletes and 49.8% for non-athletes groups(p<0.05). The experience of the use of mouth-guards was 83.3% for athletes and 78.8% for non-athletes, there were not significant differences between athletes and non-athletes groups (p>0.05). Risk factors found to be significantly related to the occurrence of maxillofacial injury were: unused mouth-guards(OR=2.83), no rules for use of mouth-guards(OR=2.46). Conclusions : Based on the findings, maxillofacial injuries experience is highly associated with mouth-guards usage, not only athletes also general people should be educated on the use of mouth-guard in order to reduce the incidence of maxillofacial injuries.

  • As carotid-cavernous fistula is the major complication that can be occurred uncommonly after maxillofacial injuries, it is abnormal arteriovenous communication between cavernous sinus and internal carotid artery. Such an arteriovenous communication is most often the result of injuries, but need not be associated with bony fracture. It usually begins soon after an injury, but it may be delayed for as long as several months. It begins undramatically with eye pain, headache and slow protrusion of eye ball. A bruit may be heard above the eye with stethoscope. Close examination will reveal dilatation of superficial veins of the eyelid and forehead and periorbital edema. There will be complete or partial ophthalmoplesia of the affected eye. Compression of the common carotid artery on the ipsilateral side will reduce or obliterate the bruit. The lesion in the cavernous sinus is them demonstrable by angiography.

  • Objectives: This study investigated patients with oral and maxillofacial lacerations who visited the emergency room over a three-year period in an effort to determine the optimal treatment for these injuries. Materials and Methods: This study examined 1,742 patients with oral and maxillofacial lacerations with 2,014 different laceration locations who visited the emergency room of Pusan National University Hospital (Busan, Korea) over three years, from January 2011 to December 2013. Patients were classified by sex, age, visit day, cause of injury, injury site, and the presence or absence of soft tissue and tooth injuries. Results: The male to female ratio was 2.50:1. Patients under 10 years old were seen most frequently. Most emergency room visits were on weekends. Among intra-oral lacerations, the lip area was the most vulnerable site; among extra-oral lacerations, the chin area was most frequently injured. The most frequent etiology was a slip down. Most lacerations occurred without bone fracture or tooth damage. Conclusion: Laceration may differ in large part as compared with the fracture. Therefore, it is necessary to continue collecting data on oral and maxillofacial lacerations to establish optimal emergency room diagnosis and treatment strategies.

  • Objectives: The mandible and other parts of the maxillofacial region suffer significant morbid injuries following road traffic accidents. Our study gives epidemiological description of mandibular fractures in Ghana and also evaluates the relevance of closed reduction and indirect fixation for managing mandibular fractures in low-resource health facilities in low-income countries like Ghana. Patients and Methods: This is a retrospective study involving 268 patients who reported to the Department of Oral and Maxillofacial Surgery of the Sunyani Regional Hospital with mandibular fractures from January 2010 to December 2019. Patient medical records were assessed for information on age, sex, fracture etiology, anatomic location of fracture, time of day of road traffic accident, and other associated injuries. Results: A total of 268 patients were included in this study (males, 216 [80.6%]; females, 52 [19.4%]). Motor vehicular accident (MVA) was the leading cause of mandibular fractures (202 injuries, 75.4%). Other etiologies included assault (39, 14.6%), gunshot (13, 4.9%), falls (12, 4.5%), and industrial accidents (2, 0.7%). Of the 161 male cases caused by MVA, 121 (75.2%) occurred at night and in the evening while the remaining 40 (24.8%) occurred in the morning and afternoon. Among all managed 222 patients, 212 (79.1%) were treated with closed reduction and indirect fixation technique while 10 (3.7%) were treated with open reduction and direct fixation. Conclusion: Closed reduction with indirect fixation could successfully be used to manage mandibular fractures in low resourced health facilities, especially in low-income countries. The poor lightening system on roads in Ghana is a major contributory factor to motor vehicular accidents.

  • Background: Through the analysis of clinical data, we attempted to investigate the etiology and determine the risk of severe iatrogenic lingual nerve injuries in the removal of the mandibular third molar. Methods: A retrospective chart review was performed for patients who had undergone microsurgical repair of lingual nerve injuries. The following data were collected and analyzed: patient sex, age, nerve injury side, type of impaction (Winter's classification, Pell and Gregory's classification). Ratios for the respective lingual nerve injury group data were compared with the ratios of the respective data for the control group, which consisted of data collected from the literature. The data for the control group included previous patients that encountered various complications during the removal of the mandibular third molar. Results: The lingual nerve injury group consisted of 24 males and 58 females. The rate of female patients with iatrogenic lingual nerve injuries was significantly higher than the control groups. Ages ranged from 15 to 67 years, with a mean age of 36.5 years old. Lingual nerve injury was significantly higher in the patient versus the control groups in age. The lingual nerve injury was on the right side in 46 and on the left side in 36 patients. There was no significant difference for the injury side. The distoangular and horizontal ratios were the highest in our lingual nerve injury group. The distoangular impaction rate in our lingual nerve injury group was significantly higher than the rate for the control groups. Conclusion: Distoangular impaction of the mandibular third molar in female patients in their 30s, 40s, and 50s may be a higher risk factor of severe lingual nerve injury in the removal of mandibular third molars.

  • Penetrating injuries in the head and neck region are not common but can pose difficult situations to manage properly. In small cross-sectional area, the neck housed many vital structures, such as carotid artery, internal jugular vein, cervical spines, esophagus, laryngotracheal complex and nerves. Because each vital structure is located within the fascial compartments, bleeding into these closed spaces can give rise to compression of surrounding structures, which may result in compromised airway. Therefore, management of the penetrating injuries should be based on the fully understanding of anatomical relationships, accurate clinical examinations, a careful history taking and the proper treatment planning. We present two cases of penetrating injuries in the head and neck region and discuss on the clinical considerations for the proper management with the literature review.

  • Purpose : The purpose of this study was to investigate the correlation between stress and maxillofacial injuries in male students. Methods : The subjects were 386 male students who were 18 years or more. Mean age was $20.99{\pm}2.80$ years. Data were collected using a self-reported questionnaire from March 7 to March 28, 2013. We surveyed maxillofacial injuries, mouth guards use and stress in male students majoring physical education. The data were analyzed by Cochran's Mantel-Haenszel, McNemar test and logistic multiple regression. Results : Those who had clenching habit and maxillofacial pain accounted for 48.7%. The pain was 3.23 folds higher in clenching habit than those who had not (OR=3.23, p <.001). The more stress they had, the more clenching habit (OR=2.13) and pain(OR=1.68) did they have. Within 2 years, those having maxillofacial injury accounted for 53.2% and 78.6% of them put on maxillofacial protection guard. In rule for mouth guard use, 39.9% had no maxillofacial injury. Maxillofacial injury was 2.41 folds higher in those who had no mouth guard usee (OR=2.41). Conclusion : Maxillofacial injury had a close correlation with mouth guard use and stress. Therefore, it is very important to establish the rule for mouth guard use in sports activities.

  • Statement of problem: In spite of increasing sports injury, there was no collected data on the rate and type of dental injuries for athletes in Korea. Purpose: The purpose of this study was to investigate the occurrence of maxillofacial injuries and attitude of college sports player in Korea towards mouthguard. Material and methods: Total 617 athletes answered a series of questionnaire concerning their sports injury and using mouthguard. Results: 1. 81%(502) of athletes had, playing or training a sports, suffered an injury. Female athletes suffered an injury more than male athletes(p<0.05). Contact sports athletes were injured more than non contact sports athletes(p<0.05). 2. 335 athletes(54.8%) had suffered maxillofacial injuries while playing or training. 81.8% of athletes suffered an maxillofacial injury in contact sports(p<0.05). 3. Laceration of oral area, wrick in neck, fracture or avulsion on upper incisors, concussion, TMJ injury, fracture or avulsion on lower incisors, fracture or avulsion on lower molars were frequently injured area. 4. 67.2% of athletes answered that mouthguard could prevent sports injury especially high in contact sports(p<0.05). But only 39.1% of athletes required mouthguard while playing. 44.6% of athletes showed their intention of using mouthguard. Conclusion: This study shows that the incidence of maxillofacial injuries is very high while the actual use of mouthguard is very low. To prevent sports injury, a dentist must inform sports players and coaches of accurate information about mouthguard so that they can use it well. A dentist also has to provide them with better mouthguard on the basis of user's complaint.
