BackgroundMicroaggressions are subtle verbal or behavioral insults (intentional or unintentional) that typically convey negative or hostile attitudes towards marginalized groups. We aim to study microaggressions and workplace culture amongst European otolaryngologist -head and neck surgeons (E-OTOHNS). The perception of "differential treatment" based on individual traits was used as a proxy for microaggressions.

Objective: To propose a European consensus for managing and treating laryngopharyngeal reflux disease (LPRD) to guide primary care and specialist physicians.

Methods: Twenty-three European experts (otolaryngologists, gastroenterologists, surgeons) participated in a modified Delphi process to revise 38 statements about the definition, clinical management, and treatment of LPRD. Three voting rounds were conducted on a 5-point scale and a consensus was defined a priori as agreement by 80% of the experts.

Objectives: Three-dimensional (3D) printing has been incorporated into medical research and numerous applications have been reported since its development in the 1980s. Ear, nose and throat (ENT) surgery is one of the fields that 3D printing is gaining increasing popularity, as it can contribute to surgical training, patient education and bioengineering. This article aims at providing an updated review of 3D printed models applications in improving ENT trainees' surgical skills.

Article Synopsis
  • * A group of 48 international experts used a modified Delphi process to review and reach a consensus on 48 statements regarding LPR, achieving agreement on 38 of them (79.2%) after three voting rounds.
  • * The consensus defines LPR as a disease caused by reflux of stomach contents affecting the upper aerodigestive tract, and highlights specific symptoms and diagnostic tools to aid clinicians in recognizing and diagnosing the condition.

Introduction: Pharyngocutaneous fistula (PCF) remains the most frequent complication following total laryngectomy (TL). Pharyngeal closure with a surgical stapler (SAPC) has been proposed as an effective closure technique that decreases the rate of PCF, reduces surgical time, decreases the length of hospital stay, and shortens the time required before safely initiating oral feeding.

Methods: This study involved a systematic review and meta-analysis of patients with laryngeal cancer who underwent TL and with subsequent stapler pharyngeal closure, in order to analyse the current literature regarding the role of SAPC after TL.

Background: Laryngopharyngeal reflux (LPR) is a common disease in otolaryngology characterized by an inflammatory reaction of the mucosa of the upper aerodigestive tract caused by digestive refluxate enzymes. LPR has been identified as the etiological or favoring factor of laryngeal, oral, sinonasal, or otological diseases. In this case series, we reported the atypical clinical presentation of LPR in patients presenting in our clinic with reflux.

Mucormycosis is a type of fungal infection more prevalent among immunosuppressed patients, requires prompt identification and surgical treatment, as it can is associated with local and distant spread. This case is aiming to highlight the importance of early identification of subtle symptoms in immunocompromised patients. The clinician should be aware of fungal sinusitis, consider it in the differential diagnosis, and seek for an ear, nose, and throat opinion.

Objective: To study the management of laryngopharyngeal reflux (LPR) among the subspecialties of practicing otolaryngology-head and neck surgeons and their trainees.

Methods: A survey was sent to over 8000 otolaryngologists (OTOHNS) over 65 countries, utilizing membership lists of participating otolaryngological societies. The outcomes were answers to questions regarding LPR knowledge and practice patterns, and included queries about its definition, prevalence, clinical presentation, diagnosis, and treatment.

Purpose Of Review: The aim of the review is to review the recent literature on the use of opioids in post sinus surgery care.

Recent Findings: Research regarding the use of opioids in post sinus surgery over the past two years support previous thinking that there is an overprescription of opioids for an operation which is not particularly painful, resulting in the potential for narcotic abuse and misuse.

Summary: Large randomized controlled trials with detailed pain recording scoring systems are needed to assess the opioid requirements - if any - after sinus surgery.

Objective: To investigate worldwide practices of otolaryngologists in the management of laryngopharyngeal reflux (LPR).

Methods: An online survey was sent on the management of LPR to members of many otolaryngological societies. The following aspects were evaluated: LPR definition, prevalence, clinical presentation, diagnosis, and treatment.

Laryngopharyngeal reflux (LPR) is a common disease in the general population with acute or chronic symptoms. LPR is often misdiagnosed in primary care because of the lack of typical gastroesophageal reflux disease (GERD) symptoms and findings on endoscopy. Depending on the physician's specialty and experience, LPR may be over- or under-diagnosed.

Objectives: Surgical management of large sinonasal tumors, spreading to the pterygopalatine, and infratemporal fossae have always been a challenge for the ENT surgeon and the multidisciplinary team.

Methods: Endoscopic Denker's approach allows complete exposure of the anterior, inferior, and lateral recesses of the maxillary sinus, without necessitating a gingivobuccal or a transseptal incision. Moreover, endoscopic Denker's approach facilitates direct, straight entry to the pterygopalatine and infratemporal fossae.

Lasers have been used in otolaryngology for more than 40 years and are widely considered an established way of addressing laryngeal pathology, benign and malignant. Carbon dioxide (CO) laser is considered a gold standard, but over the last 2 decades, a new technology has been developed and established in other medical specialties, not so much in Ear Nose and Throat (ENT), the diode laser. It consists of a flexible fiber that passes through a hollow guidance system and is capable of reaching certain angled spots easier than straight beam systems.
