I'm not aware of any research on the feasibility/stability of bimax in the context of condylectomy without joint replacement. The approach of Wolford and followers, wherein the condyle is completely removed and replaced with an artificial joint prosthesis in the context of bimax, has good evidence of stability. I suspect (without evidence) that nobody in the UK follows Wolford's treatment philosophy. Given the known risks of bimax relapse in the context of untreated TMJ pathology/disc displacement prior to surgery, I understand the hesitation to proceed.
