A Retrospective Study On Condylar Fracture Patients

Objective Oral and Maxillofacial exposed surface of the body vulnerable to injury, damage to the chewing function, body appearance and the accompanying destruction of social and psychological barriers, which is far more important than damage to other parts of the body. Condyle on the anatomy and biomechanics of the reasons for mandibular fracture easily when subjected to trauma. A retrospetive study in 119 condylar fracture patients (166 sides),to summarize the treatments for condylar fracture, and to provide future clinical work for information.Method Inpatients with reference to ICD-9 diagnosis codes in the E code, through the computer information, medical records from the hospital room in June 1999 -2009 all the first, second and third cases of condylar fracture was diagnosed. Out-patient cases to find ways to obtain by hand. By telephone, send a letter, etc. appointments were, for review, The clinical data on the incidence of each age, sex, cause of injury, fracture type, complicated injuries, treatment and sequelae such as detailed records,and statistical analysis.Results Condylar fracture occurred mainly in adults over the age of 18, accounting for 73.11%;More men than women, male to female ratio was 1.77:1.The traffic accident(51.26%) was the leading cause of condylar frature;Fall injuries (10.92%) are children and the elderly patients common causes.Comdylar neck(66.38%) was the most fracture site ,73.11% of the case had complicated maxillofacial fractures. The high-position fractures and (or) the non-obviously displaced fractures mostly took the conservative treatment(26.89%),however ,middle- or low-position fractures, and (or) the obviously displaced fractures were mostly operated.Conclusions condylar fractures of the high risk group is young adults, the most common causative factors for traffic injuries. The treatments for condylar fracture include conservative treatment and operation, which depends on the age of the patient, location of the fracture, and degree of displacement. The high-position fractures and (or) the non-obviously displaced fractures mostly took the conservative treatment, however ,middle- or low-position fractures, and (or) the obviously displaced fractures were mostly operated.
