Vessel Dissection

This study describes the surgical technique and intra- and postoperative complications associated with the use of a radiofrequency bipolar coagulator in a series of 18 Piver type III-IV radical hysterectomies performed in cervical cancer patients. Preliminary vessel-by-vessel dissection of the lateral parametria was possible in 17 out of 18 (94%) cases, and a direct application of a radiofrequency bipolar coagulation instrument was performed to coagulate the posterior and anterior parametrial tissues in all cases. We were able to easily coagulate isolated vessels up to 5 mm of maximal diameter. In no case were clamps or hemoclips necessary to complete hemostasis. We did not observe any parametrial vessel damage or heat-related injury of the surrounding normal tissue. The median size of the parametria removed was 44 mm (range 31–58) and nodes were detected in 15 cases (83%). Median operative time and estimated blood loss for the whole procedure including systematic pelvic and aortic lymphadenectomy was 250 min (range 200–410) and 550 ml (range 400–2500), respectively. Median follow-up time was 9 months (range 5–13). No complications specifically related to the use of radiofrequency coagulation were found. In conclusion the radio-frequency coagulation with this instrument appears to be a safe technique that is particularly useful in reducing blood loss and operative time without affecting radicality in patients undergoing radical hysterectomy.

Initial Results

abstract In this communication the authors describe a method for the surgical treatment of glossopharyngeal neuralgia by percutaneous radiofrequency coagulation of Andersch's petrous ganglion. The report is of the initial results in 12 cases, including 1 case of primary glossopharyngeal neuralgia. The usual indication for the procedure is intractable pain due to local neoplasia of the oral area. At the time of operation complementary radiofrequency coagulation of both the gasserian ganglion and the cervical radicular nerves can also be carried out.

✓ The authors describe investigations in cats to delineate a vasodilator system to the face, which they undertook after a previous study showed that radiofrequency coagulation of the trigeminal ganglion produced a pronounced flush in the skin of the corresponding division. Results demonstrate a vasodilator system emerging from the brain stem with the facial nerve which, by way of the greater superficial petrosal nerve, reaches the trigeminal ganglion. There the fibers are distributed to each of the divisions of the fifth nerve; in addition, a moderate number of vasodilator fibers also appear to leave the brain stem directly with the trigeminal nerve. Vasodilator effects were elicited by stereotaxic stimulation of the facial and trigeminal nuclei in the brain stem. There is, therefore, a dual vasomotor control of the facial cutaneous vascular bed; the classical sympathetic vasoconstrictor system of the face is complemented by a vasodilator system capable of producing changes of equal but opposite amplitude in vessel caliber.

Radiographic Landmarks

✓ The authors describe surgical and anesthetic techniques for the treatment of trigeminal neuralgia by radiofrequency coagulation. Using radiographic landmarks derived from a stereotaxic study of 54 cadaver skulls, they delineate lateral and anteroposterior guidelines which aid in the percutaneous penetration of the foramen ovale. Controlled lesions can be made selectively in any division of the trigeminal nerve. The procedure has been effective in abolishing pain usually with preservation of touch sensation in the face. The percutaneous operation has the added advantage of a short hospitalization, usually 2 days. Of the 65 patients treated, only one still has the pain of trigeminal neuralgia. In six instances the procedure had to be repeated because insufficient sensory deficit was produced by the initial lesion. Three patients have developed anesthesia dolorosa; however, none has developed facial paralysis.

Aim. To assess the effectiveness of modern methods of diagnosis and surgical treatment of night snoring. Methods. Conducted was polysomnography in 117 patients suffering from snoring at night. In the case of evident signs of obstruction, patients were offered surgical treatment. Results. Out of 117 people with snoring polysomnography revealed obstructive sleep apnea syndrome: in 35 - mild form, 11 - moderate severity, 1 - severe. In 69 patients benign snoring was revealed, which does not lead to a decrease in blood oxygen saturation. Simultaneous complex surgical treatment was performed in 38 patients who according to polysomnography revealed upper airway obstruction. The obstruction was eliminated by endoscopic surgical correction of the intranasal structures and the nasopharynx, and minimally invasive uvuloplasty using the method of radiofrequency coagulation. Postoperatively the patients received local medications biclotymol (hexaspray), fusafungine (bioparox), rinsing of the pharynx with antiseptics. Positive effect (disappearance of snoring) was achieved in 29 patients after an average of 1.5-2 months after surgery, in 6 patients with obstructive sleep apnea syndrome of the II and III degree of severity and co-morbidities the episodes of apnea and hypopnea decreased significantly. In 3 patients with recurrent polypous rhinosinusitis secondary to bronchial asthma (2 patients) and encephalopathy (1 patient), surgical intervention (endoscopic polysinusotomy, radiofrequency uvuloplasty) did not achieve the desired effect and the patients were referred for conservative treatment. Conclusion. The method of polysomnography and surgical treatment strategy of night snoring meet the modern requirements and in most cases have shown to be effective.
