Background: Auricular reconstruction is one of the most challenging procedures in plastic surgery. An adequate skin envelope is essential for cartilage framework coverage, yet few good options exist without additional surgery. We propose a novel method for minimally invasive tissue expansion, using hyaluronic acid (HA) filler to allow for single-stage ear reconstruction. Objectives: To introduce the novel concept of HA filler for tissue expansion in ear reconstruction, and as an alternative to traditional expansion techniques...

Endoscopic ear surgery (EES) is increasingly a preferred technique in otologic society. It offers excellent visualization of the anatomical structures directly and behind the corners with variable angled telescopes. It also provides reduced operative morbidity due to being able to perform surgical interventions with less invasive approaches. Operative preparation and setup time and cost of endoscopy system are less expensive compared with surgical microscopes. On the other hand, the main disadvantage of EES is that the surgery has to be performed with 1 single hand...

BACKGROUND: Isocapnic hyperventilation (IHV) is a method that shortens time to extubation after inhalation anaesthesia using hyperventilation (HV) without lowering airway CO2 . In a clinical trial on patients undergoing long-duration sevoflurane anaesthesia for major ear-nose-throat (ENT) surgery, we evaluated the utility of a technique for CO2 delivery (DCO2 ) to the inspiratory limb of a closed breathing circuit, during HV, to achieve isocapnia. METHODS: Fifteen adult ASA 1-3 patients were included...

Domenico Cuda, Alessandra Murri
To combine the benefits of perimodiolar stimulation with minimal insertion trauma, a thin, pre-curved electrode (CI532) was recently developed by Cochlear Ltd. (Sidney). This array is held straight prior to insertion by an external polymer reloadable sheath that is removed after full electrode insertion. Sixty-seven patients suffering from severe-to-profound sensorineural hearing loss (mean age 42.2 years; mean duration of the hearing loss 19.6 years; mean PTA thresholds at 250-2000 Hz 92.4 dB HL) were implanted with the CI532...

Introduction  Acquired atresia of the external auditory canal is characterized by the formation of fibrous tissue in the medial part. The causes include chronic otitis externa, perforated chronic otitis media, postoperative or idiopathic healing problems. Acquired atresia presents with hearing loss and can be associated with otorrhea. Objective  We analyzed the results of surgery after six months and two years by checking (1) pre- and postoperative hearing thresholds; (2) presence of otorrhea; and (3) whether a dry and patent ear canal is achieved...

Stephanie Elyse Ambrose, Norman Wendell Todd
INTRODUCTION: The plain 'cochlear view' radiograph for checking cochlear implant electrode coiling and depth of insertion is strongly influenced by positioning. The best accuracy and inter-observer agreement are achieved with the X-ray beam passing through the axis of the modiolus, which is perpendicular to the plane of the basal turn of the cochlea. The basal turn of the cochlea generally is 45 from the head's sagittal plane. OBJECTIVE: To describe a simple reliable technique of patient positioning to maximize the accuracy of postoperative radiographs in the evaluation of cochlear electrode insertion...

For neurosurgeons, who are accustomed to the binocular microscope, there is a new learning curve that must be overcome for monocular endoscopic pituitary surgery. Different studies describe a learning curve between 15 and 200 procedures, after which both operative time and complications stabilize. In this retrospective study, we evaluate the endoscopic learning curve of our group, already trained in microsurgical transsphenoidal surgery, with the assistance of ear, nose, and throat (ENT) surgeons. From 2010 to 2015, a total of 95 patients with pituitary adenomas were treated with a purely endoscopic approach...

HYPOTHESIS: A vasopressin-induced endoymphatic hydrops model can represent an acute vertiginous attack in Menière's disease (MD). BACKGROUND: Previous animal models are not appropriate to evaluate the efficacy of new treatments for hydrops because they cannot represent an acute attack of MD. Recently, a new dynamic model was introduced for acute hydrops exacerbation using the vasopressin type 2 receptor agonist, desmopressin (1-deamino-8-D-Arginine vasopressin, VP); however, resulting changes in vestibular function have not been investigated...

BACKGROUND: Otosclerosis is a progressive middle-ear disease that affects conductive transmission through the middle ear. Ear-canal acoustic tests may be useful in the diagnosis of conductive disorders. This study addressed the degree to which results from a battery of ear-canal tests, which include wideband reflectance, acoustic stapedius muscle reflex threshold (ASRT), and transient evoked otoacoustic emissions (TEOAEs), were effective in quantifying a risk of otosclerosis and in evaluating middle-ear function in ears after surgical intervention for otosclerosis...

Imaging of middle-ear cholesteatoma with diffusion-weighted imaging (DWI) magnetic resonance imaging (MRI), and inner-ear endolymphatic hydrops (in Ménière's disease) with post-gadolinium high-resolution MRI, are reviewed. DWI MRI provides for a more specific diagnosis of tympano-mastoid cholesteatoma. There is an established and increasing role of DWI MRI in detecting both primary and postoperative cholesteatoma, localising disease, and planning surgery. The contemporary diagnostic accuracy of DWI is reviewed, pitfalls in interpretation are described, and potential future developments are highlighted...

BACKGROUND: Pain management in children after tonsil surgery is essential, and optimal pain treatment has been discussed for many years. Data from the National Tonsil Register in Sweden (NTRS) and a national mapping have demonstrated the need for national pain treatment guidelines for pediatric tonsil surgery. As a result, Swedish national guidelines, together with updated patient information on the website tonsilloperation.se, were developed and implemented in 2013. OBJECTIVES: The objective of this study was to evaluate the professionals' opinions of and adherence to pain treatment guidelines for pediatric tonsil surgery patients in a two-year follow-up...

BACKGROUND: Composite grafts are frequently used for facial reconstruction. However, the unpredictability of the results and difficulties with large defects are disadvantages. Adipose-derived stem cells (ADSCs) express several cytokines, and increase the survival of random flaps and fat grafts owing to their angiogenic potential. METHODS: This study investigated composite graft survival after ADSC injection. Circular chondrocutaneous composite tissues, 2 cm in diameter, from 15 New Zealand white rabbits were used...
