Freestyle pedicled perforator flaps: safety, prevention of complications, and management based on 85 consecutive cases.
2011
Background: Despite the widespread use of free perforator flaps, pedicled perforator flaps seem not to be as widely accepted, probably because of the fear of vascular complications caused by transfer of a flap attached only by its vascular pedicle, prone to shearing, kinking, and trauma. In this article, the authors report on their experience with 85 consecutive cases, focusing on incidence, prevention, and management of complications. Methods: Eighty-five consecutive cases were treated over 6 years at the Plastic and Reconstructive Surgery Department of the University of Palermo for defects of different causes that were reconstructed with a freestyle pedicled perforator flap, in every regi…
Second study on the recurrence risk of isolated esophageal atresia with or without trachea-esophageal fistula among first-degree relatives: no eviden…
2013
BACKGROUND Esophageal atresia with/without trachea-esophageal fistula (EA/TEF) denotes a spectrum of severe congenital malformations. The aim of this systematic study was to determine both the recurrence risk for EA/TEF, and the risk for malformations of the VATER/VACTERL association spectrum, in first-degree relatives of patients with isolated EA/TEF. METHODS A total of 108 unrelated patients with isolated EA/TEF were included. These individuals had 410 first-degree relatives including 194 siblings. The presence of EA/TEF and malformations of the VATER/VACTERL association spectrum in relatives was systematically assessed. Data from the EUROCAT network were used for comparison. RESULTS None…
Laparoscopic-assisted Retropubic Midurethral Sling Placement: A Technique to Avoid Major Complications
2015
Abstract Study Objective To describe a technique for the safe placement of retropubic midurethral slings in patients undergoing concomitant laparoscopic surgery in order to avoid major complications associated with this procedure such as bladder perforation and retropubic hematomas. Design Step-by-step video demonstration of the technique. Setting A university tertiary care hospital. Patients Patients with an indication for retropubic midurethral sling placement because of recurrent stress urinary incontinence, intrinsic sphincter deficiency, or severe pelvic organ prolapse in whom a concomitant laparoscopic surgery has to be performed for other medical conditions. Intervention Laparoscopic…
Double Retrotransverse Foramen of Atlas (C1)
2018
Background The retrotransverse foramen is a nonmetric variant of C1 that consists of an abnormal accessory foramen on the posterior root of the transverse process. Case Description During a study on the prevalence of the retrotransverse foramen in 150 dry C1 vertebrae, we observed an exceptional C1 (0.67%) with a right double retrotransverse foramen of the 14 C1 vertebrae (9.3%). This has not been reported previously in the literature. No osteogenic reaction and no degenerative signs were observed in this C1 with the double retrotransverse foramen. Conclusions Neurosurgeons should be aware of the possible presence of the “conventional” retrotransverse foramen and the “exceptional” double re…
Non-syndromic supernumerary premolars
2010
Objective: The objective of this study was to estimate the incidence of non-syndromic supernumerary premolars, to classify them and to identify the complications related to them. Study Design: This retrospective cohort study was composed of 8400 panoramic radiographs of patients who presented at our Oral and Maxillofacial Surgery Services from January 1998 to May 2008. The number of supernumerary premolars, their localization, the ages and the sex of the patients, any associated complications and treatment methods were estimated. Results and Conclusion: A total of 20 supernumerary premolar teeth were found in 10 of the 8400 patients (0.24%) with 7 of those being females and three males. Thr…
Anatomical characteristics and visibility of mental foramen and accessory mental foramen: Panoramic radiography vs. cone beam CT.
2015
Background: The mental foramen (MF) is a small foramen located in the anterolateral region of the mandible through which the mental nerve and vessels emerge. The knowledge on the anatomic characteristics and variations of MF is very important in surgical procedures involving that area. The aim of this study was two-fold: firstly, to analyze the anatomic characteristics of MF and the presence of accessory mental foramen (AMF) using CBCT and, secondly, to compare the capability of CBCT and PAN in terms of MF and AMF visualization, as well as influencing factors. Material and Methods: A sample of 344 CBCT scans was analyzed for presence and characteristics (i.e. diameter, area, shape, exit ang…
Characteristics of anatomical landmarks in the mandibular interforaminal region: A cone-beam computed tomography study
2011
Objectives: This study was conducted to assess appearance, visibility, location and course of anatomical landmarks in mandibular interforaminal region using cone-beam computed tomography (CBCT). Study design: A total of 96 CBCT examinations was re-evaluated to exploit anatomical landmarks. The examinations used the Promax 3D CBCT unit. A sole examiner carried out all the measurements. Visibilities of the anatomical landmarks were scored using a four-point rating scale. Results: The mandibular foramen, anterior loop, incisive canal and lingual foramen were observed in 100,84,83,49 % of the images, respectively. The mean size, diameter and width of anterior loop, incisive canal and lingual fo…
A retrospective radiographic evaluation of the anterior loop of the mental nerve: Comparison between panoramic radiography and cone beam computerized…
2014
Objectives: To compare the prevalence and the length of mental loop, measured with panoramic radiography (PR) and cone beam computerized tomography (CBCT). Material and Methods: PG and CBCT images where analyzed by a single calibrated examiner to determine the presence and the position of the mental foramen (MF), its distance to the lower mandible border, the anterior length of the mental loop (ML) and the bone quality in 82 PR and 82 CBCT. Results: ML was identified in 36.6 % of PR and 48.8 % of CBCT. PR showed a magnification of 1.87 when compared to CBCT. The mean of anterior extension of the inferior alveolar nerve and the distance to the inferior border of the mandible was higher for P…
Localization of Congenital Tegmen Tympani Defects
2007
Objective: This study sets out to demonstrate the normal developmental steps of the tegmen tympani and thus explains the typical localization of congenital tegmental defects. Specimens: For this study, 79 macerated and formalin-fixed human temporal bones from 14th fetal week to adults were observed and prepared. Intervention: Macroscopic and microscopic examination of the prenatal and postnatal changes of the tegmen tympani during its development. Main Outcome Measure: Temporal bones from 14th fetal week to adults underwent descriptive anatomic studies to understand the normal development of the tegmen tympani and to find a possible cause of its congenital defects. Results: The medial part …
Endoscope-assisted Brain Surgery: Part 2—Analysis of 380 Procedures
1998
Objectives Microsurgical techniques and instruments that help to reduce intraoperative retraction of normal intracranial neuronal and vascular structures contribute to improved postoperative results. To achieve sufficient control of the operating field without retraction of neurovascular components, the resection of dura and bone edges is frequently required, which, on the other hand, increases operating time and operation-related trauma. The use of endoscopes may help to reduce retraction and, at the same time, may help to avoid additional dura and bone resection. The aim of this study is to describe the principles on which the technique of endoscope-assisted brain surgery is based, to giv…
