Ankylosis of temporomandibular joint after the traumatic brain injury: a report of two cases

Abstract

Mouth opening limitation after the neurosurgical procedures is a common complication and usually resolves within 3 months. If limited mouth opening remains unresolved on the long term, an intra-articular ankylosis of temporomandibular joint may develop eventually. The possible mechanisms base on the myositis and atrophy of the masticatory muscles for these craniotomies are often involved in the temporalis. This article reports two unusual cases with the intra-articular ankylosis of temporomandibular joint after the traumatic brain injury, who received a modified surgical treatment for joint ankylosis. Therefore, the early diagnosis and intervention are important to minimize these complications.

Stimulating Factors and Origins of Precursor Cells in Traumatic Heterotopic Ossification Around the Temporomandibular Joint in Mice

“…Traumatic heterotopic ossification around the temporomandibular joint (THO-TMJ) may lead to ankylosis of the TMJ in some patients (Meng et al, 2013), which not only limits the degree to which the mouth can open but also causes serious cranio-maxillofacial development deformities (He et al, 2014). The pathogenic mechanism of THO-TMJ is complicated, and immune-inflammatory responses caused by trauma in the local microenvironment may disrupt the balance between osteoblasts and osteoclasts around the TMJ (Shehab et al, 2002;Dai et al, 2016).…”
