본 연구의 목적은 소아 청소년에서 발생한 하악 과두 골절의 빈도, 원인, 골절의 임상적 양상 및 치료 방법에 대한 후향적 분석을 통해 연령에 따른 하악 과두 골절의 임상적 특징 및 치료방법을 조사하는 것이었다. 최근 10년간 아주대학교 치과병원에서 하악 과두 골절로 진단받고 치료받은 만 15세 이하의 환자 44명을 대상으로 후향적 분석을 시행하였다. 하악골 골절 중 하악 과두 골절의 빈도는 환아의 연령이 어릴수록 높았다. 하악 과두 골절의 원인으로 넘어짐의 비율이 가장 높았다. 만 4 - 7세 군에선 과두부(condyle head) 골절이 91.7%를 차지하였으며, 연령이 증가할수록 과두경부(condyle neck) 골절 비율이 증가하였다. 하악 과두 골절 환아의 54.5%에서 하악 정중부 골절이 동반되었으며, 정중부 골절이 동반된 경우 구치부 치아 손상 빈도는 하악 과두 골절 단독인 경우에 비해 높았다. 44명 환아 중 43명에서 보존적 치료가 시행되었으며, 양측 과두의 심각한 골편 변위를 가진 1명 환아에서 관혈적 수술이 시행되었다. 본 연구 결과는 소아 청소년에서 발생한 하악 과두 골절의 진단 및 치료 계획 수립에 의미있는 자료로 적용될 수 있을 것이다.

Introduction: Condylar fractures are common in the maxillofacial region, comprising 29-40 percent of all mandibular fractures, accounting for about 20-62 percent). Previous studies reported that pediatric condylar fractures can cause disorders in facial growth and function, and the treatment methods have been controversial. Recently, conservative treatment has shown good results in skeletal growth and functional recovery but the conservative treatment of pediatric condylar fractures has shown unpredictable and undesirable results in some cases, such as facial asymmetry and temporomandibular joint disorder. This study examined the specific age groups and specific mandibular condylar fracture type in growing children treated conservatively in the past. Materials and Methods: Eighteen patients (10 men and 8 women) who received conservative treatment for unilateral condylar fractures in Dankook University Dental Hospital between 2000 to 2007 were followed up for a mean period of 7.2 years. Results: In the survey of 18 pediatric patients who received conservative treatment for condylar fractures, the incidence of temporomandibular dysfunction and growth disturbance was 45% and 35%, respectively. Conclusion: In all complications, the symptoms observed most frequently was mouth opening displacement of the mandible exceeding 2 mm. The other complications of functional and growth disturbance included facial asymmetry concentrated along specific condylar types. Complications including facial asymmetry and functional and growth disturbances showed an increasing tendency according to the specific fracture types. Functional and growth disturbances in the undisplaced condylar fracture type showed a lower incidence(P <0.05). Functional and growth disturbances differed according to the fracture type, which has poor relationship with articular fossa and condyle(P <0.05). Functional and growth disturbance in the cases of the high-level condylar fracture type showed a higher incidence(P <0.05). The functional and growth disturbances of the fracture types were similar in the fragment-contact and non-contact groups(P >0.05).

Purpose: The treatment of children mandibular condyle fracture that is severely displaced is controversial. The conservative treatment of it may lead to complications - mandibular deficiency, asymmetry, malocclusion and temporomandibular joint dysfunction. Moreover, open reduction carries risks for growth retardation, facial nerve injury, scarring and joint stiffness. The aim of this article is to present an alternative technique of the treatment by using a threaded Kirschner wire and external rubber traction. Materials: From November 2005 to May 2008, three patients underwent the management by using a threaded Kirschner wire and external rubber traction. A threaded Kirschner wire was inserted in the condylar segment by using a C-arm. We applied the external rubber traction, and we reducted the segment progressively until complete reduction. The mandibular - maxillary fixations were removed after 3 weeks, and patients went into training for mouth opening. Results: The technique didn't result in complications - joint dysfunction, facial nerve injury, sore, infection and nonunion during follow - up period. Radiologic follow - up examinations revealed correct reduction in all patients. In all cases, we found restoration of preinjury occlusion and temporomandibular joint function. Conclusions: Closed reduction of children mandibular condyle fracture by using a threaded Kirschner wire and external rubber traction did achieve anatomic reduction and restore mandibular height. This alternative technique is simple, effective, inexpensive, easy to apply and minimally invasive.

하악의 골절은 아이들의 악안면 영역 골절 중 높은 빈도로 발생하며, 성장기의 환자에서 악골의 골절은 성인의 골절과 구별된 처치가 필요하다. 골편의 변위가 심하지 않다면 비관혈적 정복술과 추가적인 악간 고정을 시행할 수 있으며 악관절 강직을 예방하기 위한 기능적 운동이 필요하다. 하악의 골절 이후 여러 합병증이 발생할 수 있다. 특히 과두 골절의 경우, 골절 이환 측에서 성장장애를 일으켜 부정교합과 안면비대칭을 야기할 수 있다. 하악의 골절 이후 성장 장애가 발생한 경우, 환자에 따라 catch-up growth가 일어날 수 있으므로 주기적인 관찰이 필요하다. 성장장애가 지속되는 경우엔 안면 비대칭이 심해지는 것을 방지하기 위해 기능성 장치의 사용을 고려할 수 있다. 본 증례에서는 하악의 골절 이후 안면비대칭을 보이는 2명의 환자를 장기적으로 관찰하고 의미 있는 결과를 나타내고 있기에 이를 보고하는 바이다.

The management of mandibular condylar fractures in children has long been a matter of controversy. The fracture, if not treated appropriately, may result in complications such as disturbance of mandibular growth and temporomandibular joint ankylosis. They are usually treated nonsurgically, which has been proved to be satisfactory in the long term results. Nineteen children with 25 condylar fractures experienced during their growth period (age at trauma from 10 months to 12 years, mean 7.0 years) were studied. All patients were treated by arch bars and intermaxillary fixation for $7{\sim}14$ days. They have been evaluated with clinical and radiographic examination. The maximum mouth opening and lateral movement of the mandible were within normal limits. There was no malocclusion or ankylosis. Beginning of remodelling was evident at postoperative $1{\sim}3$ months. Remodelling of the condyle was good in 21, while partial adjustment occured in the other 4 condyles. These results suggest that the conservative treatment of condylar fractures in growing children results in good functional results and good remodelling of the condyle.
