Abstract:

Different pathologies can originate mandibular ankylosis that affect the temporomandibular articulation as to the surrounding structures. The most commonly associated causes are traumatic (31-98%), local or distant infections (10-49%) and the systemic illnesses (10%), as ankylosing espondylitis, rheumatoid arthritis, lupus erythematous or psoriasis.

They have been described a great variety of surgical techniques for the treatment of the temporomandibular (TMJ) ankylosis, including articular total TMJ replacement prosthesis, as well as multiple homologous interference materials, heterologous and synthetic used to avoid the reankylosis of the dried up bony fragments .

Presented communication describes two surgically treated cases by means of:

1. Aggressive resection of the ankylotic segment.

2. Associated coronoidectomy if is necessary.

3. Interference flap temporalis muscle.

4. Early mobilization and physiotherapy.

Case report 1.

52 year-old woman that presented both ankylosing espondylitis TMJ affectation several years old. Pre-treatment oral opening of 23 mm. Difficulty with speech, mastication, oral hygiene and chonic local pain. Post-treatment oral opening: 19 mm. Good functional improvement.

Case report 2.

30 year-old male with postraumatic bilateral mandibular ankylosis (old bilateral intracapsular fractures). Oral opening of 12 mm, without condilar translation movement. After surgical treatment and later rehabilitation, the oral opening were 26 mm.
