| Research Abstract |
A new arthroscope, which has a channel for endscopic surgery of the temporomandibular joint (TMJ), and the instruments needed for this surgery have been recently developed. In the past, two techniques (single puncture and double puncture techniques) were used for endoscopic surgery of TMJ.The single puncture technique can be subdivided into the blind technique and the direct visual technique. The blind technique has a disadvantage in that a precise surgery is not possible. The direct visual technique has disadvantage in that because the arthroscopic lens systems used for this technique need a channel for surgery, and the diameter of this endoscope is thick (3.8X2.0 mm) and causes a relatively high surgical damages. The double puncture technique has a disadvantage in that much skill is needed for maneuvering the surgical instruments (inserted through a separate cannula) into the visual field of the arthroscope inserted through another cannula. Following the recent development of a very small diameter fiberscope with a high pixel number (15,000 pixel), we have recently developed a new arthroscope, designed to resolve the previous problems. This arthroscope combines a fiberscope with a surgical channel (phi1.1mm). The length and diameter (phi2.9mm) of this fiberscope cannula are identical to those of the most frequently used Striker's arthroscope cannula. At the same time, we have developed the instruments for use in surgery that would fit through the surgical channel of this arthroscope (probe, forceps, knives, cautery knives, etc.). The use of this artroscope causes less surgical damage and allows more reliable arthroscopic surgery, when compared with conventional techniques.
