Purpose: Immediate replacement of the mandibular condyle is sometime required when the mandibular condyle is involved in pathology. This study was designed to evaluate immediate replacement of the condyle using costochondral graft following disarticulation.   Patients and Methods: This  study included 11 patients, where costochondral graft was used for immediate condylar replacement following disarticulation, the condylar replacement articulated against the preserved disc. The follow up was 2 months. Assessment was conducted immediately postoperatively by radiographic examination and 2 months by direct questioning, and clinical observation.   Results: Eleven patients suffered from benign and locally aggressive lesions of the mandibles were presented in this study, there were no complications in all patients, there was no open bite, normal range of mandibular opening, the occlusion and facial form was restored. Radiographic outcome showed normal position of the replaced condyle in the glenoid fossa. Conclusions:  Immediate  reconstruction  of  the  condylar  unit  with  costochondral  graft  is a viable technique combining ease of surgery and a high success rate. Keeping in mind this was the primary stage of reconstruction and the patient will pass the second stage constructing the body area by anterior iliac crest grafting via transcutaneous approach
