Utilization of therapeutic embolization in haemorrhage caused by carcinoma of the tongue

Selective transcatheter arterial embolization, using Gelfoam, was performed in 2 patients with bleeding from tongue arteries due to carcinoma. Though the patients were in poor general condition, being in the terminal stage of cancer, there were no complications and the bleeding was successfully controlled. This method was effective in controlling haemorrhage from the tongue due to carcinoma of the tongue.

Modified Sagittal Splitting Ramus Osteotomy by Epker's Method. Comparison with Obwegeser-Dal Pont's Method.

Since 1989, modified sagittal splitting ramus osteotomy, as modified by Epker in 1977: for surgical correction of mandibular skeletal deformities, has been used at our hospital. Advantages of this procedure are safety, capability of rotating the distal segment horizontally, and maintaining a blood supply to the proximal segment. Compared with Obwegeser-Dal Ponts method, there were no obvious differences in operating time and hemorrhage dose, but the frequency of mental nerve paresthesia was decreased by Epkers method. Minimized soft tissue dissection and short lingual cut of the medial ramus can reduce many complications and simplify the operative procedure. It was suggested that modified sagittal splitting osteotomy by Epkers method was very useful for surgical-orthodontic correction of mandibular prognathism.
