Comparative StudyImage guided surgical navigation for removal of foreign bodies in the head and neck.
The removal of foreign bodies in the head and neck area is often a surgical challenge due to a combination of difficult access and a close anatomical relationship of the foreign body to vital structures. Recent developments in computer-assisted surgery (CAS) have brought major improvements to the operating rooms for maxillofacial surgeons. The purpose of this paper is to report our experience in computer assisted removal of foreign bodies from the head and neck area, based on various clinical cases. ⋯ In our opinion, the use of a computer based image guided surgical system is of great benefit when removing foreign bodies from the head and neck area. The minimally invasive access helps to prevent major complications such as injury to vital structures and allows a quicker operation.

Biography Historical ArticlePaulus Aegineta, a seventh century encyclopedist and surgeon: his role in the history of plastic surgery.
Paulus Aegineta (625-690 ad), born on the island of Aegina, practiced medicine at Alexandria. The last of the eclectic Greek compilers in the Byzantine period, he wrote an Epitome of medicine in seven books. The sixth book, which is considered the best section of his work, is devoted mainly to surgery. ⋯ This Grecian master influenced not only his own but also the subsequent ages. Rhazes, Haly Abbas, Albucasis, Avicenna, and Fabricius ab Aquapendente were the greatest physicians influenced by Paulus Aegineta. Because the work of Paulus Aegineta was the only source for many of the surgical treatises of Arabian authors, his Epitome bridged Western and Eastern medicine and conveyed surgical experience and knowledge, including several plastic surgery procedures, to the subsequent ages.

C-arm navigation is a new tool in computer assisted surgery. The aim of this study is to evaluate the accuracy of Iso-C-arm based drill holes in the proximal femur. In nine artificial proximal femura, two holes with an angle of 135 degrees and 100 degrees in relation to the shaft axis were drilled in the direction of the femoral head. ⋯ The main plane of deviation in all of the 135 degrees holes was posteriorly, whereas in the 100 degrees holes posterior deviation occurred in four cases, cranial in three cases, and in one case each caudal and anterior deviation occurred. In our opinion, the accuracy of fluoroscopy based navigation applied in the region of the proximal femur is sufficient and reproducible. This technique can be used for implant placement at the proximal femur in the future.

Interlaminar discectomy and selective foraminotomy in lumbar disc herniation.
Our objective was to assess the clinical outcome of interlaminar discectomy in patients suffering with degenerated lumbar disc lesions. We made a prospective study of 50 consecutive patients who underwent limited lumbar discectomy. The clinico-radiological parameters, type of surgery performed and the post-operative follow up were assessed. ⋯ The post-operative results were good in 43 (86%fair in 6 (12%) and poor subjective in 1 case (2%). No patient was classified as poor objective. In conclusion, interlaminar discectomy without laminotomy is a safe, effective and reliable surgical technique for treating properly selected patients with herniated lumbar disc at L4-5 and L5-S1 levels.
