Augmented reality based middle and inner ear surgical procedures

2020

Otologic procedures involve manipulation of small, delicate and complex structures in the temporal bone anatomy which are in close proxmity of critical nerves and blood vessels. Augmented reality (AR) can highly benefit the otological domain by providing supplementary anatomical and navigational information unified on a single display. However, despite being composed of mainly rigid bony structures, the awareness and acceptance of possibilities of AR systems in otology is fairly low. This project aims at developing video-based AR solutions for middle and inner ear surgical procedures.We propose two applications of AR in this regard. In the first application, information about middle ear cle…

Clinical and radiological course in apicoectomies with the Erbium : YAG LASER

2007

A study is made of the efficacy of the Erbium: YAG laser in granulomatous periapical lesions, based on clinical and radiographic controls. The study comprised a series of 45 patients amenable to periapical surgical treatment of incisors, canines and premolars. A conventional surgical technique was used, with silver amalgam retrograde filling and irradiation of the bone defect and remnant root cement with the Erbium: YAG laser. Clinical and radiographic controls were made during 24 months, assessing the absence of symptoms and the presence of pain, swelling or fistula and ossification of the lesions, respectively. The clinical course proved asymptomatic in 95.5% of the cases. As regards remo…

Prognostic factors in the treatment of Ewing's sarcoma

1987

From 1981 up to February 1985, a total of 93 protocol patients entered the study CESS 81. The protocol recommended an initial 18-week period of polychemotherapy (VACA) followed by local therapy and two additional cycles of chemotherapy. Local therapy consisted either of radical surgery or of incomplete resection plus postoperative irradiation with 36 Gy or of radiotherapy alone (46 and 60 Gy). Centrally located lesions were always irradiated with 60 Gy. This article summarizes the data after 5 years. Data of 93 patients were analysed in October 1986 after a median follow-up of 37 months. The projected 5-year survival is 50%. The relapse rate was 42%, distant relapses occurred in 19%, local …

Experience in a Military Trauma Surgery Department with External Skeletal Fixation of Femur Fractures

1989

Our experience with external skeletal fixation of complex open and closed femoral fractures in 50 conventional trauma victims is presented. Different external fixator systems were primarily used in 26 patients and secondarily in 24 patients. The authors feel that early definitive femoral fracture care in civilian and military trauma victims employing unilateral external monofixation, which avoids casts, and allows improved wound management and early mobilization of the multitrauma patient, has decreased the complication rate commonly associated with internal fixation of open femoral fractures.

Die Struktur der kieferorthopädischen Erstberatung

1987

In den vorliegenden Ausfuhrungen uber die kieferorthopadische Erstberatung soll deutlich gemacht werden, das das Beratungsgesprach vom Beginn bis zur Entscheidung fur oder gegen die Behandlung ein komplizierter Vorgang ist, bei dem nicht nur fachliche Kenntnisse auf der Seite des Beraters von Wichtigkeit sind. Das Gesprach zwischen ihm und dem Patienten bzw. den Patienteneltern sollte nach bestimmten Gesichtspunkten gefuhrt werden, wobei neben der Ermittlung der Motivation sowie der Erfassung des intellektuellen Niveaus des Patienten auch das soziale Umfeld in die Betrachtung einbezogen werden mus. Dabei darf auch die juristische Seite nicht vernachlassigt werden. Es wird eine in Mainz entw…

Infective Endocarditis: Preliminary Results of a Cohort Study in the Southern Italian Population.

2020

Background Infective endocarditis (IE) is an uncommon disease with an involved interplay of clinical and surgical team management. We aimed to define diagnosis parameters and delineate in-hospital management in patients with IE admitted in a tertiary hospital of Southern Italian. Materials and methods Fifty-six consecutive patients (42 males, 14 females; age range: 34-85 years) admitted for IE in the Infectious Diseases, Cardiac Surgery, and Cardiology units, between January 2011 and August 2017, were enrolled. Demographic data, mortality, comorbidities, specimen type, microscopy results, special histological staining performed, and antimicrobial therapy were collected and analyzed. Any com…

New intramedullary locking nail for olecranon fracture fixation--an in vitro biomechanical comparison with tension band wiring.

2010

The aim of this study was to determine the difference in displacement of a newly designed intramedullary olecranon fracture fixation device compared with multifilament tension band wiring after 4 cycles and 300 cycles of dynamic continuous loading.In eight pairs of fresh-frozen cadaver ulnae, oblique olecranon fractures were created and stabilized using either newly designed intramedullary olecranon nail or multifilament tension band wiring. The specimens were then subjected to continuous dynamic loading (from 25 N to 200 N) using matched pairs of cadaveric upper extremities. The Wilcoxon test was used to determine statistical differences of the displacement in the fracture gap.After 4 cycl…
