Objective:
To study the impact of postoperative radiotherapy (RT) on titanium plate mandibular reconstruction.
Methods:
Between 1997 and 2002, 66 patients with oral cavity cancers had immediate titanium plate mandibular reconstruction. Thirty-four patients (51.5%) received postoperative RT and 32 patients were treated with surgery alone. Follow-up ranged from 12 to 58 months (median, 24 months).
Results:
Sixteen of 66 patients (24.2%) had major complications. Ten of 34 patients (29.4%) who received RT had complications compared with 6 of 32 patients (18.8%) after surgery alone (P = 0.312). The plate was removed in 11 patients (16.7%). The success rate of titanium plate reconstruction was 27 of 34 patients (79.4%) who received RT and 28 of 32 patients (87.5%) after surgery alone (P = 0.378).
Conclusion:
The addition of postoperative RT did not increase the risk of complications or the likelihood of successful titanium plate reconstruction.
