Disk Repositioning Surgery of the Temporomandibular Joint With Bioabsorbable Anchor

Abstract

The most common temporomandibular joint (TMJ) pathologic disease is anterior-medial displacement of the articular disk, which can lead to TMJ-related symptoms.The indication for disk repositioning surgery is irreversible TMJ damage associated with temporomandibular pain. We describe a surgical technique using a preauricular approach with a high condylectomy to reshape the condylar head. The disk is anchored with a bioabsorbable microanchor (Mitek Microfix QuickAnchor Plus 1.3) to the lateral aspect of the condylar head. The anchor is linked with a 3.0 Ethibond absorbable suture to fix the posterolateral side of the disk above the condyle.The aims of this surgery were to alleviate temporomandibular pain, headaches, and neck pain and to restore good jaw mobility. In the long term, we achieved these objectives through restoration of the physiological position and function of the disk and the lower articular compartment.In our opinion, the bioabsorbable anchor is the best choice for this type of surgery because it ensures the stability of the restored disk position and leaves no artifacts in the long term that might impede follow-up with magnetic resonance imaging.

Endoscopic Brow Lift Fixation With Mitek Suture Anchors: A 9-Year Experience of a New “Ideal” Technique

“…As it remains within the bone, this device is absorbed and integrated within 3 to 6 months. These unique qualities lend the Mitek anchor to a variety of applications in the fixation of soft tissue to bone in hand 38 and craniofacial surgery, 39 where its high tensile strength and low complication rates have been well described. To date, however, this device has not been described for fixation of the brow in brow lift procedures.…”

Disc stability after condylar discopexy with open surgery technique. A case report.

“…The treatment of TMJ dysfunction is widely debated in the literature, with good results reported for both arthroscopic techniques and open surgery; however, relapses are also reported, which determine the stability of the therapeutic resolution over time (Spallaccia et al, 2013).…”

“…This option could correct the anterior disc displacement of the right joint and improve facial asymmetry, but it would leave a scar on the face and have many surgical risks. 17,18 Furthermore, the long-term stability of TMJ surgery remains uncertain. [17][18][19] No extraction plan was considered because of the patient's nonextraction request, although this option might have resulted in a slightly more protrusive profile.…”
