Localization of mandibular foramen (MF) is highly important in different aspects of oral and maxillofacial surgery. Management of post-ankylotic patients with distorted mandibular ramus necessitates study of the changes, that might be induced in MF area. The present investigation can provide prediction for the possible changes of the location of the MF. The gained information will not only help in post-ankylosis orthognathic surgery, but will be of guidance in daily management of TMJ patients in local anesthesia and inferior alveolar nerve (IAN) block. The aim of the present study is to analyze the position of mandibular foramen in patients of TMJ ankylosis. The present study comprised 44 persons. They were distributed into two groups; Group I ankylosed group, comprised 14 patients suffering from temporomandibular joint (TMJ) bony ankylosis and Group II Normal group, included 30 normal subjects. All patients were selected from those attending the outpatient clinic of Oral and maxillofacial surgery department, Faculty of oral and dental medicine, Cairo university. Reference lines were used to localize position of the mandibular foramen (MF) in ankylosed patients and normal subjects by the use of three dimensional computed tomography (3D-CT). The collected data were tabulated and statistically analyzed in order to detect any possible changes that might be induced by TMJ bony ankylosis
