Simulation for training in sinus floor elevation: new surgical bench model
2011
Objectives: to describe a bench model (workshop of abilities) for sinus floor elevation (SFE) training that simulates the surgical environment and to assess its effectiveness in terms of trainees’ perception. Study design: thirty-six randomly selected postgraduate students entered this cross-sectional pilot study and asked to fill in an anonymous, self-applied, 12-item questionnaire about a SFE workshop that included a study guide containing the workshop’s details, supervised practice on a simulated surgical environment, and assessment by means of specific check-lists. Results: Thirtiy-six fresh sheep heads were prepared to allow access to the buccal vestible. Using the facial tuber, third …
Alveolar ridge reconstruction with titanium meshes: A systematic review of the literature
2014
Alveolar bone regeneration by means of titanium meshes is a widespread procedure, however to date, only few relevant studies were reported in literature concerning this technique. Consequently, the aim of the present systematic review was to analyze the reliability of the titanium mesh as a barrier, in conjunction with horizontal and vertical ridge reconstruction for implant placement purposes. A total of 17 articles complying with the inclusion and exclusion criteria were reviewed. Three outcome variables were defined: a) horizontal and vertical bone regeneration obtained, b) complication rate, defined as the percentage of membrane exposures and c) evaluation of implant survival, success a…
Bladder augmentation and urinary diversion in patients with neurogenic bladder: Non-surgical considerations
2011
Segments from almost all parts of the bowel have been used for urinary diversion. As a result, the available absorptive surface area of the bowel is reduced, and the incorporation of bowel segments into the urinary tract may have metabolic consequences. This is an area somewhat neglected in the literature. Metabolic complications are rare, but sub-clinical metabolic disturbances are quite common. Several studies have demonstrated that some of the absorbent and secreting properties of the bowel tissue are preserved after incorporation into the urinary tract. Hyperchloraemic metabolic acidosis can occur if ileal and/or colon segments are used, as well as malabsorption of vitamin B(12) and bil…
Horizontal and Vertical Reconstruction of the Severely Resorbed Maxillary Jaw Using Subantral Augmentation and a Novel Tenting Technique with Bone fr…
2013
Aim The aim of this study was to evaluate the effect of using the lateral wall bone in sinus lifting two-dimensional reconstruction on bone augmentation.Patients and Methods Ten patients affected by class V or VI maxillary atrophy with less than 3 mm of residual horizontal ridge were selected. Using a piezo-ultrasonic surgery tip bony lateral wall was cut. To expose native bone to the bone graft, multiple perforations, made through the cortical plate of the recipient site with a round bur. Once the bony buccal wall was adjusted it was fixed away from the ridge with two 1.5 x 13 mm bone fixation screws. Deficiencies created between the bony buccal wall and the ridge was filled with a mineral…
Continent urinary diversion and bladder augmentation in children: the Mainz pouch procedure.
1989
The formation of a bowel reservoir of large capacity at low pressure by using small and large bowel (ileocaecal segment) has proved reliable for achieving continent urinary diversion (n = 80), for bladder augmentation (n = 42) as well as for total bladder replacement (n = 24). Encouraged by the results we obtained in our adult patients, we have used this technique during the last 3.5 years in 29 children. Indications for urinary diversions in children have been: neurogenic bladder with diplegia (n = 8), bladder exstrophy (n = 2), traumatic loss of the bladder (n = 1), urogenital sinus (n = 1) and rhabdomyosarcoma of the prostate or bladder (n = 2). Bladder augmentation was indicated in 6 ch…
Ureterocystoplasty in a Boy with Myelomeningocele
2010
Introduction In the rare case of a decompensated neurogenic bladder combined with a unilateral hydronephrosis and hydroureter, ureterocystoplasty is a feasible and elegant technique for bladder augmentation. In contrast to augmentation using bowel segments, the use of urothelial-lined tissue avoids the common problems caused by mucus development and electrolyte disturbance. Prerequisite is a unilateral non-functional kidney and a severe dilation of the ureter. Patients The patient presented in this case report is an 11-year old boy with myelomeningocele. Due to a decompensated neurogenic low-compliance bladder with high-degree reflux, the left kidney was hydronephrotic and afunctional, urod…

Complications in the treatment with alveolar extraosseous distractors: literature review
2014
Background To review the literature that analyses the types and frequency of complications associated with the use of extraosseous alveolar distraction from 2007 to 2013. Material and Methods Review of the literature in PubMed, using these keywords; alveolar ridge, alveolar distraction osteogenesis, complication, literature review. Inclusion criteria were: articles published between 2007 and 2013 that included the distraction protocol, the complications encountered and the time when they occurred. Results According to the above criteria, 12 articles were included in this review, where 334 extraosseous distractors were placed and 395 complications were encountered, of which 19 (4.81%) were i…
Clinical and Radiological Long-Term Outcome of a Tapered Implant System with Special Emphasis on the Influence of Augmentation Procedures
2015
Background and Purpose: Tapered implant designs aim to improve primary stability and implant survival in soft bone. However, respective clinical long-term data are scarce. Therefore, a clinical and radiological evaluation of the long-term success of a transgingival-supracrestal inserted tapered implant system with special emphasis on the influence of augmentation procedures was conducted. Material and Methods: In a retrospective study design, all in the Department of Oral and Maxillofacial Surgery of the University Medical Centre, Mainz, Germany, between May 2002 and March 2012, placed tapered implants (Straumann TE®, Basel, Switzerland) were analyzed. In this time period, a total of one hu…
Doctor, quiero una talla 100
2009
Cuando una paciente consulta al cirujano plástico con la intención de que éste le efectúe una mamoplastia de aumento es, en la mayoría de las ocasiones, difícil interpretar exactamente el volumen que desea. La determinación del volumen de la mama que posee la paciente y del volumen que quisiera tener se ve limitada por inconvenientes técnicos y por la poca precisión en la interpretación psicosocial de las mediciones y cálculos que se pueden hacer. El objetivo de este estudio ha sido desarrollar un sistema que partiendo de las medidas intrínsecas del sujetador permita relacionar el volumen de la mama de la paciente con el volumen de la copa del sujetador que desea y con la prótesis necesaria…
