Anatomic Changes After Hyoid Suspension for Obstructive Sleep Apnea: An MRI Study

2005

Objective To assess the effects of isolated hyoid suspension on subjective and objective parameters of obstructive sleep apnea and to evaluate changes in upper airway anatomy with the help of standardized magnetic resonance imaging. Study design and setting Fifteen patients received isolated hyoid suspension. Changes in respiratory disturbance index were assessed with polysomnography, and anatomical changes with standardized magnetic resonance imaging. Snoring, daytime sleepiness, and functional parameters were assessed with questionnaires. Lateral x-ray cephalometry was performed preoperatively. Results Mean respiratory disturbance index was reduced from 35.2 ± 19.1 to 27.4 ± 26.2. Forty p…

Morphologic outcome of bimaxillary surgery–An anthropometric appraisal

2014

Objectives: To adequately perform orthognathic surgery procedures, it is from basic interest to understand the morphologic changes caused by orthognathic surgery. Anthropometric analyses of standardized frontal view and profile photographs could help to investigate and understand such changes. Study Design: We present a pre- to postoperative evaluation of orthognathic surgery results based on anthropometric indices described by Farkas and cephalometric measurements. 30 Class III patients undergoing maxillary advancement by Le Fort I Osteotomy and mandibular setback by bilateral sagittal split osteotomy were evaluated. Preoperative as well as three and nine months postoperative lateral cepha…

Surgical treatment and follow-up of solitary bone cyst of the mandible:a report of seven cases.

2001

We have operated on and followed up seven patients with simple mandibular bone cysts. The clinical data are shown in Table 1. All cysts were asymptomatic, and were found as a result of routine radiographs. They were all in dentulous areas in the mandible (5 in the anterior zone). Only case 5 gave a clear history of trauma in the region of the cyst 7 years before diagnosis. Vitality of the pulp of adjacent teeth was confirmed in all cases except case 6, in whom endodontic orthograde treatment of the teeth included in the lesion zone had previously been done. In all cases, the radiographs showed a unilocular radiotransparent lesion with clearly defined margins

The intravascular ultrasound morphometry of iliac veins in subjects without severe chronic venous insufficiency and its implications for treatment in…

2019

Objectives The purpose of this study is to report the intravascular ultrasound morphometry of iliac veins and its relation to demographic and anthropometric factors in subjects without chronic venous insufficiency. Methods Thirty-three patients, without chronic venous insufficiency – qualified to great saphenous vein stripping due to unilateral, primary varicose veins – participated in the study. During the surgery, left and right external iliac veins, common iliac veins and inferior vena cava were interrogated with intravascular ultrasound. The morphometric analysis included measurement of a cross-sectional area at normal, non-stenosed vein segments (ref-CSA) and at the point of the most p…

Safety and Feasibility of a New Minimally Invasive Diagnostic Laparoscopy Technique

1998

Background and Study Aims: Laparoscopy combined with guided liver biopsy offers many advantages in the diagnosis and staging of chronic liver diseases and is superior to other diagnostic procedures. We developed a new minilaparoscopic technique and evaluated the utility of this minimally invasive laparoscopic system in the first 320 patients who underwent diagnostic assessment for liver disease or peritoneal carcinosis. Patients and Methods: Between July 1996 and February 1998, minilaparoscopy, with analgesia and sedation was carried out in 320 patients. It was done using a 1.9-mm optical instrument, which was inserted through the same 2.75-mm trocar as the Veress needle used for inflating …

Permanent Stoma After Low Anterior Resection for Rectal Cancer

2010

BACKGROUND AND OBJECTIVES: A low anterior resection procedure for removing a rectal tumor aims to preserve the sphincter and avoid a permanent stoma. Permanent stomas are primarily necessary in cases of poor anorectal function and local recurrence. The aim of this study was to clarify whether anastomosis-related complications and local recurrence influenced the rate of permanent stomas in a long-term follow-up. METHODS: Of 1032 consecutive patients with rectal cancer, 397 were treated by low anterior resection (R0 and R1 resections) between 1985 and 2007 at the Department of General and Abdominal Surgery of the University Hospital, Mainz (Germany). All patient data were collected prospectiv…

Subfascial Endoscopic Perforator Surgery With Tumescent Local Anesthesia

2002

background. Subfascial endoscopic perforator surgery (SEPS) has become an established procedure. objective. To evaluate SEPS with tumescent local anesthesia (TLA) using an single-port device originally designed for that purpose. methods. Patients selected for SEPS received subcutaneous infiltration of TLA into the medial aspect of the calf 20 minutes before surgery. Bipolar coagulation and dissection were used to treat incompetent perforators. results. Fifty-one patients with 67 legs of CEAP stages C3–C6 underwent SEPS with TLA. In 40 patients or 53 legs (79.1%) TLA alone allowed successful completion of the SEPS procedure. Five patients with 7 legs (10.4%) required additional intravenous a…

Cystic vestibular schwannoma: classification, management, and facial nerve outcomes.

2009

OBJECTIVE: Review of postoperative morbidity and facial nerve outcomes of cystic vestibular schwannoma (CVS) patients compared with solid vestibular schwannoma (SVS) patients and a proposal for a new CVS classification system. STUDY DESIGN: Retrospective review. SETTING: Tertiary care facility. PATIENTS: Ninety-six patients with surgically treated CVS (1998-2008). Outcomes were assessed in a subpopulation of 57 patients with greater than or equal to 1-year follow-up compared with 57 SVS patients. INTERVENTION: Fifty-six CVS patients underwent the enlarged translabyrinthine approach with transapical extension (Type I), and 1 patient underwent a transcochlear/transzygomatic approach. MAIN OUT…

Simple endoscopic decompression of cubital tunnel syndrome with the Agee system: anatomic study and first clinical results.

2010

BACKGROUND Simple decompression in ulnar nerve compression syndromes offers options for endoscopic applications. OBJECTIVE The authors present their initial experience with the Agee device. PATIENTS AND METHODS The monoportal endoscopic technique (Agee system) was evaluated on 10 cadaveric arms. Subsequently, 32 arms of 29 patients were operated on between January 2006 and March 2009. All patients presented with typical clinical signs and neurophysiologic studies. Long-term follow-up examinations were obtained in 27 of 32 arms. RESULTS In the cadaver study, the ulnar nerve was always correctly identified. No nerve damage occurred, and sufficient decompression of the ulnar nerve was always a…

Endoscopic decompression of the ulnar nerve at the elbow.

2010

OBJECTIVE: Recently, several studies suggested that simple decompression is as effective as anterior transposition in ulnar nerve entrapment syndrome. Simple decompression might be performed with minimally invasive techniques. The authors present their technique and results with endoscopic decompression in ulnar nerve entrapment syndrome. MATERIAL AND METHODS: Between January 2005 and March 2008, 24 patients (mean age, 45.5 years; range, 26-67 years) underwent surgery for 26 ulnar nerve entrapment syndromes (2 bilateral). All patients presented with typical clinical signs and neurophysiologic studies. RESULTS: Intraoperatively, the ulnar nerve was localized directly at the sulcus, and subse…
