We sought to follow-up a cohort of patients who had miniplates (plates) inserted in the oral and maxillofacial region during a 13-month period over 4 years to study the incidence and factors associated with plate removal.
One hundred fifty-three patients had plates inserted in the oral and maxillofacial region in the Department of Oral & Maxillofacial Surgery, University Hospital Birmingham, UK, between November 1, 1998, and November 30, 1999. All 153 patients' records were revisited on or after October 31, 2002, giving a minimum follow-up of 3 years and a maximum of 4 years.
During a period of 13 months (November 1, 1998 through November 30, 1999), 308 plates were inserted into 153 patients. A total of 32 plates were removed from 21 patients by October 31, 2002, (10.4%) over 4 years; 27 plates were removed from 16 patients for purely plate-related symptoms, with infection being the most common cause accounting for 16 plates (50%) in 9 patients. Symptoms necessitating plate removal occurred within 52 weeks after insertion in 16 patients, accounting for 23 of the plates removed (72%). The age of the patient at plate insertion may have some influence on plate removal but this was not significant. Seniority of the operator did not affect plate removal.
Our experience with the removal of miniplates compares with previously published reports. Longitudinal follow-up at 4 years indicates that plate-related problems leading to removal are likely to occur in the first year after insertion.
我们对一组在4年中的13个月内在口腔颌面区域植入微型钢板（接骨板）的患者进行随访，以研究钢板取出的发生率及相关因素。
1998年11月1日至1999年11月30日期间，英国伯明翰大学医院口腔颌面外科有153例患者在口腔颌面区域植入了接骨板。2002年10月31日或之后复查了所有153例患者的记录，随访时间最短3年，最长4年。
在13个月期间（1998年11月1日至1999年11月30日），153例患者共植入308块接骨板。到2002年10月31日的4年中，共有21例患者取出了32块接骨板（10.4%）；16例患者因单纯与接骨板相关的症状取出了27块接骨板，感染是最常见的原因，9例患者中有16块接骨板（50%）。16例患者在植入后52周内出现需要取出接骨板的症状，取出的接骨板中有23块（72%）是这种情况。患者植入接骨板时的年龄可能对取出接骨板有一定影响，但不显著。手术医生的资历不影响接骨板的取出。
我们取出微型钢板的经验与先前发表的报告一致。4年的纵向随访表明，导致取出接骨板的与接骨板相关的问题很可能在植入后的第一年出现。
