Abstract
Abstract The present invention provides improved methods for correction of temporomandibular joint internal derangement with closed lock via small incision surgical technique. In one embodied form, the unique method comprises the steps of: (a) effecting visualization and orientation of the surgical site of a patient utilizing an arthroscopic device comprising a mechanism for prescribed calibration of the arthroscope depth; (b) effecting arthroscopic inspection of the surgical site, and in particular, the superior compartment of the temporomandibular joint; and (c) effecting lysis comprising resection and incision of adhesions disposed between disc and fossa of the temporomandibular joint region, concommittent with disc displacement. The inventive surgical technique includes an "arthroscopic sweep" of the superior compartment of the TMJ with lysis comprising resects of superior compartment adhesions. Subsequent to lysis, the superior compartment is thoroughly lavaged via irrigation and suction. Preferably, a pressure dressing is placed to cover the surgical wound, and can be removed within about 12 hours from the surgical procedure.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
136 words
An improved method for correction of temporomandibular joint internal derangement with closed lock via small incision surgical technique, said joint comprising a mandibular condyle, superior compartment having, posterior attachment and posterior fossa, the method comprising the steps of: (a) manipulating said mandibular condyle of a patient anteriorially and inferiorially; (b) entering the superior compartment of the patient's temporomandibular joint with a surgical needle and injecting therein a solution comprising anesthetic; (c) injecting into said superior compartment saline solution; (d) entering said superior compartment with an arthroscopic device for visualization of the internal condition of the temporomandibular joint; (e) determining whether synovial adhesions are present in said superior compartment of the temporomandibular joint; and (f) effecting lyses comprising resection and incision of adhesions disposed between disc and fossa of the temporomandibular joint region, concommittent with disc displacement.
Claim 2
Dependent Claim
136 words
An improved method for correction of temporomandibular joint internal derangement with closed lock via small incision surgical technique, said joint comprising a mandibular condyle, superior compartment having, posterior attachment and posterior fossa, the method comprising the steps of: (a) manipulating said mandibular condyle of a patient anteriorially and inferiorially; (b) entering the superior compartment of the patient's temporomandibular joint with a surgical needle and injecting therein a solution comprising anesthetic; (c) injecting into said superior compartment saline solution; (d) entering said superior compartment with an arthroscopic device for visualization of the internal condition of the temporomandibular joint; (e) determining whether synovial adhesions are present in said superior compartment of the temporomandibular joint; and (f) effecting lyses comprising resection and incision of adhesions disposed between disc and fossa of the temporomandibular joint region, concommittent with disc displacement.
Claim 3
Dependent Claim
35 words
The improved method for correction of temporomandibular joint internal derangement with closed lock as defined in claim 1 and further comprising the step of effecting arthroscopic sweep of said superior compartment of the temporomandibular joint.
Claim 4
Dependent Claim
39 words
The improved method for correction of temporomandibular joint internal derangement with closed lock as defined in claim 2 and further comprising the step of thoroughly lavaging the superior compartment via irrigation of saline solution and aspiration of said solution.
Claim 5
Dependent Claim
35 words
The improved method for correction of temporomandibular joint internal derangement with closed lock as defined in claim 3 and further comprising the step of introducing into said lavaged area steroid solution in said superior compartment.
