Comment on: A Modified Technique of Temporomandibular Joint Arthroscopic Operative Surgery of the Superior and Inferior Joint Spaces

Abstract Purpose This paper describes in detail the first author's technique of performing arthroscopic surgery in both the superior and inferior joint spaces of the temporomandibular joint. Methods The key is careful measurement of sagittal and coronal tomograms to determine the individual size and shape of the joint. The joint is then distracted to allow 3-port video arthroscopy. Results The detailed steps in the procedure are described and illustrated. Conclusion This modified technique is safe and allows procedures in both joint spaces and surgical access to the fossa, condyle and disc.

Periplasm of bacteria is the space outside the permeability barrier of plasma membrane but enclosed by the cell wall. The contents of this special milieu exterior could be regulated by the plasma membrane from the internal, and by the cell wall from the external environment of the cell. Unlike the gram-negative organism, the presence of this space in gram-positive bacteria is still controversial because it cannot be clearly demonstrated. We have shown the importance of some periplasmic bodies in the secretion of penicillinase from Bacillus licheniformis.In negatively stained specimens prepared by a modified technique (Figs. 1 and 2), periplasmic space (PS) contained two kinds of structures: (i) fibrils (F, 100 Å) running perpendicular to the cell wall from the protoplast and (ii) an array of vesicles of various sizes (V), which seem to have evaginated from the protoplast.
