Silicone vs temporalis fascia interposition in TMJ ankylosis: A comparison

Abstract

We conclude that silicone is comparable to temporalis fascia in terms of stability, surgical ease, and adaptability. It not only restores the function of mandible and ensures good maximum interincisal opening but also maintains the vertical ramal height. Also, it requires less operating time and is easy to handle but is not economical. It might be an effective way to restore function and prevent re-ankylosis.

Interpositional Arthroplasty for Treatment of ATM Ankylosis

“…However, this technique has a high rate of reankylosis. The results of studies in the literature are controversial [6,7]. For Aneja V, et al [9], reconstructive TMJ approaches with either autogenous grafts or alloplastic materials have common complications such as reankylosis, resorption, overgrowth, fracture and pain.…”

“…A study by Gupta S, et al [7] compared the insertion of the temporal fascia with the insertion of a silicone material in the region of the joint, in relation to the interstitial middle opening and the relapse of group A (silicone) was 4.6% and 7.9% for group B (fascia) from 9 to 10% both in the 3 rd and 6 th post operative month respectively. During the first month, there was no significant difference.…”

“…Gupta S, et al [7] reports that ankylosis is more common in the first decade of life, because children are more active and have poor motor coordination, especially in the first years of life, being easier to occur trauma leading to this change [7].…”

“…False ankylosis results from pathological conditions not directly linked to the joint [6] . The most common etiology is trauma followed by infection; rarely its cause is pathological such as rheumatoid arthritis, psoriasis, ankylosing spondylitis or joint neoplasia [2,7]. The treatment is performed surgically in order to restore its form and function [8], covering some options for approach such as: Opening arthroplasty Journal of Surgery: Open Access Open Access Journal (gap arthroplasty), Interpositional arthroplasty, ankylotic mass excision with ligament reconstruction [8].…”

Reemplazo total de articulación temporomandibular en pacientes con anquilosis: presentación de dos casos clínicos

“…Por último, se encuentran las prótesis a medida de titanio. [18][19][20][21][22][23][24][25] En pacientes en crecimiento, la mejor opción son los injertos autólogos, mientras que después de los siete años y en pacientes adultos reintervenidos que presenten reabsorción ósea, perdida de dimensión vertical o enfermedad sistémica como artritis reumatoide infantil, se tienen mejores pronósticos utilizando prótesis comerciales a la medida. 26 Las complicaciones más comunes del reemplazo total de la ATM son reanquilosis, crecimiento óseo descontrolado, resorción ósea, morbilidad del sitio donador, fractura, dolor, daño de la rama cigomática del nervio facial y presencia de mordida abierta anterior.…”
