Implantation of the Jarvik 2000 left-ventricular-assist-device: role of the maxillofacial surgeon.

The Jarvik 2000 system of axial-flow LVAD-is implanted for permanent mechanical circularly support in patients with end-stage heart failure waiting to undergo heart transplantation. The battery is connected with a power plug to the percutaneous skull-mounted footplate, which is monocortically fixated to the retro auricular bone. Patient selection should be highly specific, including careful preoperative evaluation. No device failures have been published so far, but complications can occur due to heparinisation. We describe the procedure from the perspective of the maxillofacial surgeon and give suggestions to prevent surgical complications.     

Nasal septal perforations: our surgical technique.

OBJECTIVE: The aim of this paper was to describe our surgical technique for the treatment of nasal septal perforations. STUDY AND DESIGN: We studied 31 patients with nasal septal perforation treated with an endoscope-assisted technique, based on a bilateral dissection of monopedicled mucosal flaps from the nasal fossa floor, sutured at the edge of the perforation previously unstuck, without any graft interposed between the two mucosal layers. RESULTS: In our experience with 31 patients, the use of this technique led to the persistent closing (with follow-up for at least one year) of 96.3% of the perforations smaller than 3 cm. CONCLUSIONS: Our technique has the advantage of an endonasal approach, without any external incision, and the use of monopedicled flaps from the nasal fossa floor without any graft interposition, avoiding any other surgical procedure and morbidity in the donor site of the graft. The use of nasal endoscopy permits superior precision in all surgical steps. SIGNIFICANCE: The high success rate in perforations smaller than 3 cm seems to confirm the effectiveness of this technique.     

Amputation: surgical technique and postoperative management.

The decision to amputate should be made with due consideration of the eventual rehabilitation of the patient. With this in mind, general principles of amputation surgery are outlined and specific levels of amputation are described. Early post-amputation management has advanced over the last two decades to make rehabilitation goals the more readily reached. These advances are discussed.     

A fine-cut technique for permanent laryngeal sectioning.

BACKGROUND: A new technique for permanent sectioning of the human spinal cord has provided superior images over those produced with traditional methods. Application of this technique for sections of the human larynx may yield cost-effective, efficient, and accurate laryngeal anatomic dissections. STUDY DESIGN AND METHODS: This study was designed to evaluate this technique for dissections of the human larynx. Laryngeal sections from cadavers were submerged in a celloidin solution, a derivative of wallpaper plaster, and frozen to -15 degrees C. After preparation, axial and coronal cuts of 100 microm were made with a Macrocut Tome sectioning system. RESULTS: Sections were completed in approximately 30 hours. Digitized photographs of the laryngeal sections provide detailed images of precise anatomic relationships. CONCLUSION: Celloidin-based sectioning of the human larynx yields precise anatomic information beyond standard radiographic imagining and previous permanent laryngeal sectioning techniques in a cost-efficient and timely manner. Black and white fine-section photographs are provided.     

Proctologic day-surgery. Results of 2000 surgical interventions

The aim of the study was the evaluate of results of 2000 surgical operations for ano-rectal disease performed in the day-surgery setting (7-24 hours hospital stay) with improvement of both cost effectiveness and patient comfort. From January 1980 to December 1998, 2000 patients underwent surgical operations: 1011 for haemorrhoids; 708 for anal fissure; 172 for fistula in ano; 80 for pylonidal disease; and 45 for anal stenosis. 97.6% of patients were operated on with loco-regional anaesthesia; the others with narcosis and peripheral anaesthesia. The hospital-stay was 24 hours in 697 patients (34.5%), while 1319 (65.5%) operated on under loco-regional anaesthesia were hospitalised for 7-10 hours. Three patients (0.2%) developed acute hemorrhage after hemorroidectomy during the immediate postoperative period. They underwent reintervention under general anaesthesia with a hospital stay of 7 days. Four patients (0.6%) with perianal abscess after internal sphincterotomy underwent incision 10 days after the operation. Two patients with perianal hematoma after sphincterotomy prolonged the hospital stay for three days. In 1048 patients (51.9%) clinical recovery was observed at first follow-up (7 days); 48% had recovered at the 2nd follow-up (14 days). In 1608 patients (98%) anatomical recovery was observed at the follow-up three months after surgery. Patient satisfaction 6 month after operation was high in 79%; good in 27%; low in 1%. These results seems confirm the feasibility of proctological day surgery in almost all patients, with both a considerably cost reduction and enhanced patient comfort and compliance.     

Conjunctivochalasis: a surgical technique

Conjunctivochalasis can be surgically corrected when it gives an appearance of a moist eye, produces tearing by mechanical obstruction of the lower punctum, or if it impedes the normal outflow of the lacrimal film. We present a surgical technique that provides a satisfactory anatomical reconstruction, does not leave a deformity, and will not lead to a retraction that could produce a cicatricial ectropion. We stress the importance of a complete ophthalmologic examination to rule out more common causes of tearing.     

Double gloving and surgical technique.

A comparison of double gloving versus single gloving was made with regard to its effects on tactile discrimination and dexterity in 17 surgeons of all grades and specialties. Surgeons were assessed by their ability to tie surgical knots, and Dellon's moving two-point discrimination test. Tests were performed single gloved, double gloved with the larger glove on the outside, and double gloved with the larger glove on the inside. Double gloving did not alter two-point discrimination or the ability to tie surgical knots in this study. Wearing the smaller glove on the outside of the larger glove was considered more comfortable than the conventional technique.     

Dry arthroscopy of the wrist: surgical technique

PURPOSE: To present a method to perform arthroscopic exploration and instrumentation without infusing any fluid. METHODS: The hand is suspended from a bow, with traction on all fingers. Portals are developed as in the classic (wet) wrist arthroscopic procedure except that no water is infused to distend the joint and create the optic cavity. For this procedure the joint must be dried; we use suction through the synoviotomes and neurosurgical patties to accomplish this. RESULTS: We have performed more than 100 wrist arthroscopies using the dry technique without any undue difficulty. CONCLUSIONS: The dry technique is as effective as the classic procedure, without the cumbersome leakage of water or the risk of compartment syndrome. It allows some sophisticated arthroscopic procedures to be performed that would be impracticable with water. In addition from these benefits, if open surgery is performed after the arthroscopic exploration then the tissue planes are dry, making surgery much easier. The technique is believed to be inappropriate if thermal probes are used. A learning curve exists.     

Total thyroidectomy: the evolution of surgical technique

The present paper outlines the development of thyroid surgery from early times to the twenty-first century. The significant changes that have occurred in the past few decades in relation to the evolution of techniques for safe and effective total thyroidectomy are then summarized. In the last 25 years total thyroidectomy has replaced bilateral subtotal thyroidectomy as the preferred option for the management of all patients with bilateral benign multinodular goitre, Graves' disease, and all but very low-risk thyroid cancer patients. The principal change in operative technique has been the move from 'lateral dissection' to 'capsular dissection'. Associated with that has been a focus on 'encountering' the recurrent laryngeal nerve (RLN), recognizing sympathetic-laryngeal nerve anastomoses, and routinely identifying the external branch of the superior laryngeal nerve (EBSLN). Completeness of resection has been assured by moving from an anatomically based approach to an embryologically based approach. This requires an awareness of the vagaries of thyroid development including attention to pyramidal remnants, to abnormalities associated with the tubercle of Zuckerkandl, and to thyrothymic thyroid rests. Preservation of parathyroid function has moved from the time-consuming technique of dissection of a vascularized pedicle in all cases, to initially selective, and then routine, parathyroid autotransplantation. These changes have ensured that total thyroidectomy can now be offered as a safe and efficacious procedure with a minimal complication rate.
