“…Allen and Young (1969) [4] classified lateral dislocation of mandibular condyle into: Type 1 -lateral luxation, Type IIcomplete dislocation. Satoh (1994) et al [5] sub classified type II dislocations into: Type IIA -The condyle is not hooked above the zygomatic arch, Type IIB -The condyle is hooked above the zygomatic arch and Type IIC -The condyle is lodged inside the zygomatic arch, which is fractured. But type II classification is based on anterior mandibular symphysis fracture.…”

“…The rest 6 cases were type I dislocated. The Worthington described his type of case with the term unusual and the information was not available for the case of Radhakrishkna (Table III) (Table IV) [1][2][3][4]7,10,12,13,[22][23][24][25][26][27][28] while 34 dislocations (46.26%) was managed by surgical modalities [5][6][7]9,11,14,[16][17][18][19][20][21][22]24,26,27,29] while no treatment was given for 2 cases (2.98%) resulting in fibrosseous ankylosis [4] (Table V). It can be concluded that most of all surgeons had used open reduction techniques for management of supero-lateral dislocation.…”

“…This may be because most of the cases were type II dislocations, hooked above the zygomatic arch and was difficult to be reduced by closed reduction. [10] and Satoh et al [5] earlier did condylectomy and arthroplasty by costal cartilage. Yoshi et al [16] had a case of superolateral dislocation with zygomatic arch fracture, so he temporarily removed the arch to reduce the mandibular condyle.…”

“…Satoh et al8 further subdivided type II dislocation into three subcategories: type IIA, wherein the condyle is not hooked above the zygomatic arch; type IIB, wherein the condyle is hooked above the zygomatic arch; and type IIC, wherein the condyle is lodged into the zygomatic arch. The present case fits the criteria of right-type IIB and left-type I mandibular condyle dislocations.…”

Lateral and superior-lateral dislocations of the intact condyle are a rare complication, following traumatic insult to the mandible. We report an unusual case of a 54-year-old male patient who experienced both types of dislocations of the intact condyles with symphysis fracture following a road-traffic accident. Under general anesthesia, conventional manipulation was unsuccessful in relocating the condyles into the glenoid fossa. After applying a percutaneous traction force, using a bone traction hook placed at the sigmoid notch, the displaced intact mandibular condyles were repositioned, and the symphyseal fracture was finally reduced and fixed. The mouth opening was within normal limits, and favorable occlusion was confirmed one month postoperatively. To our knowledge, this is the first case of dislocation of both intact condyles--associated with symphysis fracture--being reduced with bone traction hook.

“…They subdivided such dislocations into 2 types: type I (lateral subluxation), in which the condyle has been laterally dislocated out of the fossa, and type II (complete dislocation), in which the condyle has passed laterally and then superiorly to enter the temporal fossa. Satoh et al [4] reported 1 case and further classified type II dislocation into type IIA, in which the condyle is not hooked above the zygomatic arch; type IIB, in which the condyle is hooked above the zygomatic arch; and type IIC, in which the condyle is lodged inside the zygomatic arch, which is fractured.…”

Introduction Anterior and anteromedial dislocations of the mandibular condyle are seen frequently in mandibular fractures. Less frequent are dislocations of the condylar head in the lateral, medial and posterior direction whereas superior dislocation into the middle cranial fossa is rare. We report a series of seven cases encountered over the years, which, incidentally, is the largest case series reported till date with lateral and superolateral dislocation of the condyle after a traumatic injury. Materials and method In all cases but one, the condyle was reduced by manual manipulation with the patient in general anaesthesia. In all cases but one there was simultaneous fracture in the mandibular symphyseal region. The associated fractures were reduced and fixed with bone plates and screws. Results Patients were generally free from any long term complications of injury or surgery except for facial nerve paresis of a transient nature in one case. Conclusion To our knowledge, this clinical series presents the first reported case of superolateral dislocation which required open reduction. The etiology and mechanism of dislocation has been discussed along with a brief review of the literature.
