1 김종배 유재하 * 최병호* 계명대학교의과대학치과학교실, 연세대학교치과대학구강악안면외과학교실 ( 원주기독병원 )* Abstract CONSERVATIVE CARE OF NONUNION OWING TO OSTEOMYELITIS ASSOCIATED WITH FRACTURE OF MANDIBLE: REPORT OF 3 CASES. Jong-Bae Kim, Jae-Ha Yoo*, Byung-Ho choi* Department of Dentistry, College of Medicine, Keimyung University Department of Oral and Maxillofacial Surgery, College of Dentistry, Yonsei University( Wonju Christian Hospital)* Failure to use effective methods of reduction, fixation, and immobilization may lead to nonunion with osteomyelitis, owing to the compound nature of most fractures of the mandible. Nonunion results in fibrous pseudoarthrosis at the fracture site with instability that, once formed, does not improve spontaneously. Once the nonunion with osteomyelitis secondary to fractures has become established, intermaxillary fixation and drainage of infected tissue should be instituted as early as possible, because the fixation & drainage enhances the patient comfort and hinders ingress of microorganisms & debris by movement of bone fragments. The authors treated three cases of nonunion with osteomyelitis by intermaxillary fixation, incision & persistent drainage on the previous fistula site and endodontic drainage of infected teeth in the fracture site of mandible. The localization & sequestration of the infected bone around the fracture was better performed persistently by natural homeostatic mechanism in 8 10 weeks and the bony union was then attained without bone grafting. Key words : Mandible fracture osteomyelitis, Nonunion, Endodontic drainage, Persistent drainage. Ⅰ. 서론 악골골절부수술후비유합 (nonunion) 의원인으로는골편고정의불량, 분쇄골절편의변위, 골절편의무균적괴사, 골절편사이에연조직의게재 (interposition), 골수염과골흡수, 전신상태의불량등이고려된다 1,2). 하악골절에서비유합의결과는하악골의연속성이상실되고, 골절편의흡수로인한하악골길이의감소와섬유성위관절증으로저작, 연하, 발성, 심미, 심지어호흡기능에까지장애를초래하게된다 3,4). 하악골절부골수염에의한비유합의 1 차적인치료로는우선악간고정술을시행하여골절편이동에의한미생물의 유입을방지하고, 감염의원인이되는골절선상부치아나이물을제거하며, 골수염부위에배농로를설정하는보존적인방법들이제시되고있다 5,6). 그러나 1 차적인치료에도불구하고비유합이지속될경우에는골절편사이의염증성섬유조직, 반흔조직, 화골 (eburnated bone) 등을제거하고골이식을활용한재건술을시행케되는뎨, 이는환자에게큰부담과고통을주고기능적, 심미적결함도초래될가능성이높아 7,8) 1 차적인보존적처치가선호되고있다. 골절부골수염치료에서보존적처치의생물학적원리는하악골수염치료에서가장중요한열쇠가적절하고지속적인연조직배농로설정에있는만큼, 배농로가장기간확보 471

그후저작장애지속되어 2000 년 6 월 9 일본치과 ( 구강악안면외과 ) 로내원하였다 (Fig. 5). 구강악안면검사및방사선사진검사로하악좌측측절치와견치사이에서하방으로계단상으로의도적골절을시행하고고정한부위에서비유합및구강내농루형성이관찰되었다 (Fig. 6).

Ⅲ. 총괄및고찰 하악골절에서골수염이유발될우려가있는감염의원인으로는골절의양상이복합적일경우구강내열창, 골절선상치아주위염, 구강외창상감염, 골절편주위혈종등이고려되며, 선행소인으로는국소요소와전신적인요소들이있다 (Table 1) 1,2,4). 그러므로임상에서는골절발생시감염방지를위해우선초기고정을위한 1 차강선고정, 견고고정, 항생소염요법의조기시행, 적절한배농로설정, 골절선상치아의감염, 전신상태의개선과구강위생관리등에주력하게된다 8,9). 그러나본증례들처럼환자들이고령으로전신상태가약화되고, 골절편의고정이불량하며악성종양의수술로인한스트레스과다와면역기능감퇴 (RND 의경우경부임파절제거로인한면역약화 ) 10-12) 등은골절부주위에감염을초래해골절편의비유합을초래할우려가높다. 하악골절부골수염에의한비유합의치료법에는우선악간고정술을시행하고, 감염의원인이되는이물 ( 봉합사, 금속판과나사, 강선등 ), 실활조직, 관련치아들을제거하며, 철저한세균검사와배농로설정이중요시된다 5,13,16). 따라서 ( 증례 1) 의경우타병원성형외과에서하악골절편의고정에이용된금속판과나사를제거하고서배농로를설정했음에도비유합이초래된것은우선악간고정술이불량한상태에서골절선상치아주위염에대한처치를시행치않은데그원인이있었을것으로추정된다. 왜냐하면골절부골수염에의한비유합발생시악간고정술은골절편의운동에의한미생물의내부침투를방지하며, 골절선상치아의경우감염된치수는퇴행성변화와괴사과정을거처골절부골수염을유발하는원인이되기때문이다. 그리하여 Lieblich 등은골절선상치아들이다음의상태에있다면반드시발치할것을권유했는데 4,14,15) (Table 2), 본증례들모두에서는발치의적응증범주에있던치아들도치근관신경치료 ( 발수및배농술을장기간시행한후골절유합되면신경치료완결 ) 로서발치를하지않고보존할수있었기에의미가크다고사료된다. 왜냐하면치근관신경치료의원리자체가일반외과학의원리처럼 1 감염조직에서좌멸괴사조직의제거 ( 근관확대로치수내감염조직제거 ) 2 배농 ( 치근관개방을통한배 Table 2.

Rowe 등 4,19) 은하악골절에서비유합이발생될것으로판단되면골절편고정을위한악간고정술을오래시행하여시간을소비하는것보다는가능한한골이식을빨리시행하는것이낫다고한반면, Peacock 등 5,6,20) 은외과의사들이골이식술을너무쉽게시행하는경향이있음을지적하면서골절부주위의감염된하악골의국소화와부골화는골절부골수염주위연조적배농로의설정이정확히지속적으로시행되면자연적인치유기전즉인체의항상성 (homeostasis) 에의해훨씬더잘일어나므로비유합이예견되어도일단은 wait & see 의자세로배농술을지속해볼것을주장했다. 저자등도환자의입장에서생각해서둘러골이식을시행치 않고인내심을가지고 Peacock 의의견에따라꾸준히구강내외로배농술을시행한결과약 1 개월경에부골편이자연탈락되면서창상감염의조절및골유합을확인할수있었다. Ⅳ. 결론 저자등은하악골절부관혈적정복술과악성종양의수술을위해하악골절단및정복고정술을시행했으나비유합이발생된 3 증례를골절편고정용금속판과나사를남긴채악간고정술시행, 골절선상치아의근관통한배농술, 골수염주위연조직의지속적인배농술을통한자연적인부골분리유도등의보존적관리로서양호한골유합과창상치유를치험했다. 참고문헌 1.
