Arachnoidalzyste der Keilbeinhöhle

1998

BACKGROUND Arachnoid cysts of the paranasal sinus are rare. They have not been described yet in the sphenoid sinus. PATIENT AND METHOD Microscopic-endoscopic endonasal surgery of the sphenoid sinus was performed on a 34-year-old female with a history of chronic headaches and a suspected mucocele of the sphenoid sinus in computed tomography (CT) and magnetic resonance imaging (MRI) studies. An extended arachnoid cyst was found in the enlarged sphenoid sinus, which was obliterated with collagen, fibrin glue, and abdominal fat. RESULTS There were no complications after the operation, and 12 months later the patient is still free of symptoms. CONCLUSION Arachnoidal cysts present in CT and MRI a…

Direct and oblique approaches to the craniovertebral junction: Nuances of microsurgical and endoscope-assisted techniques along with a review of the …

2017

Purpose: The aim of this review is to provide an update of the technical nuances of microsurgical and endoscopic-assisted approaches to the craniovertebral junction (transnasal, transoral, and transcervical), and to report on the available clinical results in order to identify the best strategy. Methods: A nonsystematic update of the reviews and reporting on the anatomical and clinical results of endoscopic-assisted and microsurgical approaches to the craniovertebral junction (CVJ) was performed. Results: Pure endonasal and cervical endoscopic approaches still have some disadvantages, including their steep learning curves and their deeper surgical fields. Endoscopically assisted transoral s…

Impact of the anterior commissure involvement on the survival of early glottic cancer treated with cricohyoidoepiglottopexy: a retrospective study

2018

Eugenia Allegra,1 Vincenzo Saita,2 Alfio Azzolina,2 Massimo De Natale,2 Maria Rita Bianco,1 Domenico Michele Modica,3 Aldo Garozzo1 1Otolaryngology, Department of Health Sciences, University of Catanzaro, Catanzaro, Italy; 2Otolaryngology Unit, Cannizzaro Hospital, Catania, Italy; 3Otolaryngology Unit, University of Palermo, Palermo, Italy Background: Laryngeal early glottic tumors can benefit from different treatment modalities, including transoral laser microsurgery, open partial horizontal laryngectomy (OPHL), and radiotherapy. However, the treatment of early glottic tumors with the involvement of the anterior commissure remains controversial. The studies about the role of anterior commi…

Endoscope-assisted keyhole surgery for aneurysms of the anterior circulation and the basilar apex

2000

In the treatment of cerebral aneurysms, preoperative surgical planning and intraoperative strategies for microsurgical approaches are important issues. Within the context of minimally invasive neurosurgery, so-called keyhole approaches, especially those with intraoperative endoscopic assistance, have gained increasing interest, but their application for cerebral aneurysm surgery is a matter of ongoing controversy. The main aspects of keyhole microsurgery, with and without endoscopic assistance, for cerebral aneurysms are explained. To present the keyhole concept, which is based on the preoperative analysis and intraoperative use of pre-existing anatomic windows, this article concentrates on…

Myoperitoneale Composite Flaps: Ein neues operatives Prinzip zur Vaginalrekonstruktion

1995

In spite of the development of various techniques for the formation of a neovagina, the longterm results are often disappointing, especially if the simpler methods (dilation, ectopic pouch formation, epithelium transfer) have been applied. The more complex surgical techniques such as musculo/fasciocutaneous and colon flaps are associated with a significant risk of severe complications. For certain operative situations necessitating vaginal reconstruction, adequate procedures are still missing. Based on surgico-anatomic investigation of the vascular territories of the myoperitoneal anterior abdominal wall, we introduce the use of myoperitoneal composite flaps from the deep inferior epigastri…

Porcine Model for Gluteal Artery Perforator Flap: Anatomy and Technique

2018

Although flap anatomy is well studied on cadavers and microsurgical techniques are well practiced on rats, still there are few training models for learning the techniques of perforator flap harvesting. The cadaver has no bloodstream, so accuracy of dissection cannot be evaluated and flap viability cannot be verified. Training on humans carries a high risk of flap damage. A living model for perforator flap harvest is needed to learn the technique before starting with its clinical application.

Endoscope-assisted Craniotomy

1995

We describe a surgical technique to improve visualization of deep brain structures during craniotomy. The technique, developed in a cadaveric model, combines the use of an operating microscope and a solid-rod lens endoscope. Addition of the endoscope during craniotomy allows the operator to visualize structures that otherwise might not have been seen. An approach to the brain stem is demonstrated.

Bericht zum 1. Workshop zur lokalen Exzision von Rektumkarzinomen

2007

To determine the significance of local excision (LE) of rectal cancer and discuss oncologic results, a 1st Workshop on LE of rectal cancer was held at the Department of General und Abdominal Surgery, Johannes Gutenberg-University Mainz, Germany. The option of broadening the indication for local excision after neoadjuvant radiochemotherapy (nRCT) of rectal cancer was to be assessed. Local excision of "low risk" T 1 carcinomas was rated as oncologically adequate therapy with good functional results and low complication rates. Transanal endoscopic microsurgical (TEM) resection was the preferrred technique. Pre-requisite for the achievement of low recurrence rates (5 %) is an R0 resection with …
