Titanium Wire with Needle for Canthal Fixation
The Titanium Wire with Needle has been developed to meet the need for improved canthal fixation. The medial and lateral canthal ligaments attach to the medial and lateral orbital rims and provide palpebral fissure. Due to their position in the orbital region, these ligaments often get damaged in midfacial trauma, especially if the naso-orbital-ethmoid (NOE) area is affected, or in cases of damage to the lateral midface.
Furthermore, secondary injuries to these ligaments might appear when surgical exposure is required to gain access to these types of fractures, both in primary or secondary fracture repair. Lastly, restoration of the ligaments can be necessary in cases of congenital deformity such as Treacher Collins syndrome. Precise anatomic restoration of the ligaments is crucial for obtaining satisfactory esthetic results in the midfacial region.
When a ligament is damaged, current surgical practice typically uses stainless steel wire or nonresorbable suture to keep the reposition of the ligaments. However, the main clinical problem associated with stainless steel wire is scatter effects in postoperative imaging. A second clinical problem is the possibility of galvanic corrosion, as titanium plates and screws are often used for the fixation of fractures in close proximity to the damaged canthal ligament. Finally, stainless steel implants are known to elicit a reaction in patients with an allergy to nickel.
The new Titanium Wire with Needle directly addresses these clinical issues by causing minimal scatter, providing compatibility with titanium plates and screws, and eliminating the risk of an allergic reaction. The Titanium Wire with Needle is offered in four sizes, ranging from 26 gauge to 32 gauge. Each wire is mounted with a curved stainless steel needle which is removed after repositioning has been accomplished.
Titanium Wire with Barb and Needle
In addition to the Titanium Wire with Needle, a version with an additional barb at its end has been developed which provides hold in the canthal area.
This device can be used for both conventional transnasal wiring or for the more sophisticated technique developed by Beat Hammer. With this technique, the titanium wire is diverted via the most posterior hole of a compact midface plate that serves as a cantilever in the ipsilateral medial orbital wall region.
The Titanium Wire with Barb and Needle is available in 28 gauge wire size and is mounted with a straight stainless steel needle.
