Radial intralesional linear calcifications and focal hyperostosis: key points for diagnosis, extension and point of origin identification of sinonasal inverted papilloma.

Sinonasal inverted papilloma (IP) often appears as a unilateral sinonasal soft-tissue mass with varying enhancement, often accompanied by bone remodelling, intralesional calcifications, focal hyperostosis, and cone-shaped bone thickening (observed in 60 to 80% of cases) (1,2). A non-contrast sinonasal CT scan may reveal a soft tissue polypoid mass that closely resembles inflammatory polyps (Figure 1 A-D). While hyperostosis is recognized as a marker of the tumor's point of origin (1), intralesional calcifications are less frequently described but may offer valuable insights.

Randomized clinical trial to compare the efficacy to improve the quality of surgical field of hypotensive anesthesia with clonidine or dexmedetomidine during functional endoscopic sinus surgery.

Purpose: Intense bleeding of the surgical field is a potential factor influencing success of functional endoscopic sinus surgery (FESS). Hypotensive anesthesia with α2 intravenous agonists reduces intraoperative bleeding, but which is the best agent is unknown. The main objective of this trial was to compare the current standard adjuvant drug for hypotensive anesthesia, clonidine, with the recently available alternative dexmedetomidine.

Use of α-Adrenergic Agonists to Improve Surgical Field Visibility in Endoscopy Sinus Surgery: A Systematic Review of Randomised Controlled Trials.

Purpose: We assessed the evidence for the use of α-adrenergic agonists (A2AAs) in bleeding control and field quality in endoscopic sinus surgery.

Methods: We systematically reviewed randomized clinical trials (RCTs) assessing A2AAs in endoscopic sinus surgery. Abstracts were reviewed by 2 investigators for eligibility, and selected articles were fully reviewed.

Adaptation and validation of the Spanish version of the Tonsil and Adenoid Health Status Instrument.

Objectives/hypothesis: The Tonsil and Adenoid Health Status Instrument (TAHSI) is a disease-specific questionnaire, intended for completion by parents, for assessing quality of life related to tonsil and adenoid disease or its treatment in children with throat disorders. The aim of this study was to validate the Spanish adaptation of the TAHSI, thus allowing comparison across studies and international multicenter projects.

Study Design: Multicenter prospective instrument validation study.

A randomised double blind clinical trial to compare surgical field bleeding during endoscopic sinus surgery with clonidine-based or remifentanil-based hypotensive anaesthesia.

Background: Significant bleeding during functional endoscopic naso-sinusal surgery (FESS) impairs recognition of anatomical references and may negatively affect surgical outcome. Anaesthesia including clonidine as an adjuntive hypotensive agent may reduce intraoperative bleeding.

Methods: A randomised comparison of clonidine-based vs remifentanil-based hypotensive anaesthetic regimen was conducted in patients undergoing FESS.

Hypotensive anaesthesia and bleeding during endoscopic sinus surgery: an observational study.

Significant bleeding during functional endoscopic naso-sinusal surgery (FESS) impairs recognition of anatomical references and may negatively affect surgical outcome. Through their hypotensive effect, adjuvant anaesthetic agents may influence intraoperative bleeding. The present study compared intraoperative bleeding in patients undergoing FESS administered a clonidine-based anaesthetic regimen and in patients receiving other an anaesthetic combination with higher acquisition costs.

Electrodissection tonsillectomy with laryngeal mask.

The Colorado® microdissection needle has been used for 30 years as an alternative to cold dissection. Alexander was the first to publish the results of laryngeal mask in otorhinolaryngology and maxillofacial surgery. Later on it was introduced as a standard anaesthetic technique in our speciality.

Single surgical step for endoscopic surgery and orbital reconstruction of a silent sinus syndrome.

Silent sinus syndrome (SSS) is an uncommon disease characterised by enophthalmos, caused by ipsilateral maxillary sinus atelectasis. The diagnosis is clinical with radiological confirmation. The treatment has two objectives: to regulate the aeration of the maxillary sinus through achieving normal nasal cavity drainage and to restore the orbital architecture.

[Tympanostomy tube placement in children with secretory otitis media: analysis of effects and complications].

Introduction And Objectives: Tympanostomy tube emplacement is a common surgical procedure in paediatric otolaryngological surgery. This surgery has complications that sometimes depend on the disease and at other times on the treatment. The objective of this study is to know the results obtained with tympanostomy tube emplacement and its complications.

The effect of topical amphotericin B on inflammatory markers in patients with chronic rhinosinusitis: a multicenter randomized controlled study.

Background: It has been suggested that an exaggerated immune response to fungi is crucial in the pathogenesis of chronic rhinosinusitis (CRS). Based on this rationale, the use of topical antifungals (amphotericin B) has been advocated. Studies on its clinical effectiveness are, however, contradictory.

A dynamic upper atmosphere of Venus as revealed by VIRTIS on Venus Express.

The upper atmosphere of a planet is a transition region in which energy is transferred between the deeper atmosphere and outer space. Molecular emissions from the upper atmosphere (90-120 km altitude) of Venus can be used to investigate the energetics and to trace the circulation of this hitherto little-studied region. Previous spacecraft and ground-based observations of infrared emission from CO2, O2 and NO have established that photochemical and dynamic activity controls the structure of the upper atmosphere of Venus.

Amphotericin B nasal lavages: not a solution for patients with chronic rhinosinusitis.

Background: Chronic rhinosinusitis (CRS) is one of the most common chronic diseases. Recently, it has been suggested that an exaggerated immune response to fungi is crucial in the pathogenesis of the disease. On the basis of this hypothesis, intranasal treatment with amphotericin B should benefit patients with CRS.

Barcelona Smell Test - 24 (BAST-24): validation and smell characteristics in the healthy Spanish population.

Objectives: Smell tests for clinical use have been developed in different countries, but no single test has gained general acceptance. The objectives of the study were to evaluate the smell outcomes in a Spanish population.

Methods: A prospective study on healthy volunteers (n = 120) without olfactory disturbances was performed.
