Perforation into middle cranial fossa as a sequel to use of a proplast-teflon implant for temporomandibular joint reconstruction

Histological analysis of regeneration of temporomandibular joint discs in rabbits by using a reconstituted collagen template

“…Synthetic materials such as Silastic TM10 , Proplast TM , laminate of Teflon TM and PTFE 2,11 , alloplastic implants including pericardium 7 , in vitro cartilage 20 and frozen-stored disc materials 16 have been utilized in clinical and animal studies. Success rates for these materials vary greatly and, post-surgical results are essentially unpredictable.…”

Evaluation of Surgically Retrieved Temporomandibular Joint Alloplastic Implants: Pilot Study

“…22,26,27,29,38 In the late 1980s, Proplast/Teflon® TMJ IP were found to brake or be rejected in many patients, because of the high biomechanical forces placed on them. 20,21,25,33,36,[39][40][41][42] The breakdown lead to production of fragmented particles which resulted in an immune foreign body response 21,25,39-42 , causing problems ranging from severe cutaneous inflammatory reaction in the pre-auricular and cheek areas 43 ; to severe degenerative joint disease with resorption and erosion of the TMJ bony structures, perforation into the middle cranial fossa 44,45,46 , chronic pain, increased joint noises, TMJ hypomobility, and malocclusion. The result was a dramatic clinical spectrum of failures for these implants.…”

Bony eminence on the middle cranial fossa corresponding to the temporomandibular joint

“…This eminence may also be relevant to certain clinical procedures such as arthroscopy or implantation of prostheses in the TMJ (Van Sickels et al, 1987;McCain, 1988;Berarducci et al, 1990;Chuong and Piper, 1992).…”
