Augmented Reality of the Middle Ear Combining Otoendoscopy and Temporal Bone Computed Tomography

2018

International audience; HYPOTHESIS:Augmented reality (AR) may enhance otologic procedures by providing sub-millimetric accuracy and allowing the unification of information in a single screen.BACKGROUND:Several issues related to otologic procedures can be addressed through an AR system by providing sub-millimetric precision, supplying a global view of the middle ear cleft, and advantageously unifying the information in a single screen. The AR system is obtained by combining otoendoscopy with temporal bone computer tomography (CT).METHODS:Four human temporal bone specimens were explored by high-resolution CT-scan and dynamic otoendoscopy with video recordings. The initialization of the system…

Effects of functional endoscopic sinus surgery on the acoustics of the sinonasal tract

2017

Background: Nasal and paranasal cavities are supposed to contribute substantially to the vocal tract resonator properties. However, their acoustical effects as well as the effects of sinus surgery on the voice remain unclear. In this work we investigate resonance phenomena of paranasal sinuses prior to and after various rhinosurgical procedures in cadaveric human sinonasal tracts and corresponding 3D casts. Methodology: Nasal and paranasal cavities of formalin-preserved cadavers and corresponding 3D replicas were excited by sine tone sweeps from an earphone placed in the epipharynx.The response was picked up by a microphone at the nostrils. Different FESS procedures were performed and the a…

Neuroendoscopic Navigated One-Step Removal of Crossed Ventricular Catheter Fragments: Technical Note

2021

Abstract Introduction Neuroendoscopy plays an important role in minimally invasive neurosurgery. The authors reported an interesting case of a pediatric patient with multiple ventriculoperitoneal shunt (VPS) revision surgeries, presenting with VPS infection and with two crossed intraventricular floating catheter fragments, successfully removed through a neuroendoscopic navigated one-step procedure. A literature review regarding this exceedingly rare condition has also been discussed. Case Description An 11-year-old female patient with a history of congenital hydrocephalus was admitted to the emergency department with symptoms of intracranial hypertension, psychomotor agitation, and tetrapar…

Laika ietekme ārkārtas gastroendoskopijas veikšanā uz ārstēšanas iznākumu nevarikozas augšējas GI asiņošanas gadījumā

2018

Darba nosaukums: Laika ietekme ārkārtas gastroendoskopijas veikšanā uz ārstēšanas iznākumu nevarikozas augšējās GI asiņošanas gadījumā. Ievads: Akūta nevarikoza augšējā gastrointestinālā trakta asiņošana ir nopietna medicīniska patoloģija, kas var veicināt tālāku veselības pasliktināšanos un pat nāvi. Šī iemesla dēļ ir svarīgi analizēt agrīnas un vēlīnas ārkārtas endoskopijas ietekmi uz ārstēšanas iznākumu nevarikozas augšējās GI asiņošanas gadījumos. Darba mērķis: Mērķis ir izpētīt, vai agrīna endoskopisko izmeklējumu veikšana pacientam samazina negatīvu iznākumu riskus. Materiāli un metodes: Darbs ir veikts kā retrospektīvs kohortas pētījums. Dati tika ievākti no 2010. līdz 2017. gadam. P…

Histologic analysis of specimens from laparoscopic endometrioma excision performed by different surgeons: does the surgeon matter?

2011

Objective To evaluate whether the amount of ovarian tissue inadvertently removed along with the endometrioma cyst wall at laparoscopy differs in relation to the operating surgeon's level of expertise. Design Multicenter, prospective trial. Setting Four tertiary care university hospitals. Patient(s) Fifty patients, aged 25 to 40 years, with monolateral ovarian endometriomas who underwent laparoscopic excision. Intervention(s) Operation with the stripping technique by surgeons with specific expertise in endometriosis surgery in four centers (groups A, B, C, and D) and by residents with average training in laparoscopic surgery (group E). Main Outcome Measure(s) Histologic examination for the e…

Sialoendoscopy: state of the art, challenges and further perspectives. Round Table, 101st SIO National Congress, Catania 2014

2015

This draft of the Official Round Table held during the 101(st) SIO National Congress is an updated review on sialoendoscopy, a technique used for diagnosis and treatment of obstructive pathologies of salivary glands in a minimally invasive fashion. This review treats many aspects of salivary gland endoscopy, starting from anatomy to deal with the more advanced surgical techniques and analyses the main decisional algorithms proposed in the literature. In addition, particular attention was directed to the current limitations of this technique and to the potential developments that sialoendoscopy could have in the near future.Questo testo è un estratto della Tavola Rotonda Istituzionale tenuta…
