[Changes in the retinal vessels in mandibular nerve anesthesia. A potential for complications].

Examinations of the eyegrounds were made on thirty subjects after conduction anesthesia with xylocitin of the inferior alveolar nerve as well as on nine subjects after sodium chloride injections in order to determine the effect of mandibular conduction anesthesia on retinal vessels. Retinal vascular widths were measured and arteriovenous indices determined. The subjects were divided into groups according to preexisting general diseases, age, sex, and smoking habits. Retinal vascular changes were determined in dependence on age and smoking habits after injections made into the mandibular foramen, and the manner of origin and the results are discussed with particular reference to data reported in the literature.

Mandibular nerve paresthesia caused by endodontic treatment.

The paresthesias of the inferior dental nerve consists of a complication that can occur after performing various dental procedures such as cystectomies, extraction of impacted teeth, apicoectomies, endodontic treatments, local anesthetic deposition, preprosthetic or implantologic surgery. The possible mechanisms of nervous lesions are mechanical, chemical and thermal. Mechanical injury includes compression, stretching, partial or total resection and laceration. The lesion can cause a discontinuity to the nerve with Wallerian degeneration of the distal and integrated fibers of the covering (axonotmesis) or can cause the total sectioning of the nerve (neurotmesis). Chemical trauma can be due to certain toxic components of the endodontic filling materials (paraformaldehyde, corticoids or eugenol) and irrigating solutions (sodium hypochlorite) or local anesthetics. Thermal injury is a consequence of bone overheating during the execution of surgical techniques. We present a clinical case of paresthesia of the inferior dental nerve after the introduction of a gutta-percha point in the mandibular canal during the performance of a root canal therapy of the inferior first molar. The etiology and the treatment of this endodontic complication are described.

Mandibular nerve: MR versus CT about 10 proved unusual tumors.

10 patients with symptoms of mandibular neuralgia formed the basis of this study. They were studied by both enhanced CT and MRI. MRI, better than CT, easily permits distinction between intrinsic and extrinsic lesions and detects involvement of the cavernous sinus and meninges. Moreover, because of its multiplanar imaging capability, and ability to portray exquisite anatomic details and characteristic tissue signal intensity, MRI is helpful in the evaluation of tumor involvement for biopsy and preoperative planning for these deep tumours.
