Purpose:
To preliminarily evaluate the surgical treatment results of disc displacement of temporomandibular joint(TMJ).
Methods:
From October 2009 to September 2010, 9 patients (11 joints) with disc displacement of TMJ ( 8 females and 1 male, and with an average mouth opening of 21.3mm) underwent disc repositioning and fixation via arthroscopy or open anchorage surgery. All patients were clinically followed up at least 3 months, and MRI examinations were performed at regular intervals.
Results:
All incisions healed well and there were no severe complications. The average mouth opening increased to 32.8mm and the disc position remained favorable on MRI at the latest follow-up.
Conclusions:
With accurate diagnosis and selection of appropriate indications, disc repositioning and fixation via arthroscopy or open anchorage surgery should be used as a treatment of choice for disc displacement of TMJ.
