                                Extra-oral implants – insertion per- or post-ablation?
 Figure 2 Survival in extra-oral implants placed before (inserted before irradiation, IBI) or after irradiation therapy 4 (inserted after irradiation, IAI). (Difference between the two groups was evaluated by log-rank test and resulted
statistically nonsignificant (p = 0.225).)
Three patients lost two implants, six patients lost one implant and one patient lost three implants. The follow-up periods of the orbital and nasal implants are depicted in Figs. 3–5. Loss of orbital and nasal implants occurred after 22.8 months (range 8–87 months) and 20.9 months (range 8–82 months) in function, respectively.
