Acute suppurative thyroiditis (AST), a rare yet potentially life-threatening infection, comprises less than 1 % of neck pathologies and requires prompt treatment. Symptoms range from neck pain and fever to dysphagia and possible abscess formation. Broad-spectrum antibiotics are the primary treatment; however, surgical drainage may be necessary for abscesses to prevent systemic infection.

Purpose: This study proposes the Lamella Ostium Extent Mucosa (LOEM) system as a compact and user-friendly classification for endoscopic sinus surgery (ESS), based on surgical bone extension and mucosal management, aiming to resolve inconsistencies in describing surgical techniques and extension levels, and to enhance comparability of outcomes in chronic rhinosinusitis (CRS).

Methods: LOEM uses a lettering system representing a specific topographical level: L identifies the lamellae, O the ostia, E the opening of the sinus walls, and M the mucosal approach. Eleven CRS surgical cases were independently evaluated by seven rhinologists following a Delphi method in two consecutive rounds.

Purpose: Upper airway (UA) surgery is commonly employed in the treatment of patients with obstructive sleep apnea (OSA). The intricate pathophysiology of OSA, variability in sites and patterns of UA collapse, and the interaction between anatomical and non-anatomical factors in individual patients may contribute to possible surgical failures. This clinical consensus statement aims to identify areas of agreement among a development group comprising international experts in OSA surgery, regarding the appropriate definition, predictive factors in patients, and management of surgical failure in OSA treatment.

Article Synopsis
  • The study looked at how otolaryngologists (ear, nose, and throat doctors) can help people who have nosebleeds that just won't stop. They wanted to see if tying off or burning a certain artery (the sphenopalatine artery) would work well and safely over time.
  • Researchers reviewed 16 different studies with 454 patients; about two-thirds had the artery tied off, and the rest had it burned or both.
  • The results showed only a small number of patients had nosebleeds return or other complications, making these methods seem safe and helpful for stubborn nosebleeds.

Purpose Of Review: To present current evidence in long-term (> 5 years) results after endoscopic sinus surgery (ESS) focusing on Patients Reported Outcome Measures (PROMs) and other sinonasal outcomes while assessing the role of ESS in the treatment of CRSwNP, and identifying outcomes which affect the results of ESS and defining recommendations for future studies.

Recent Findings: Long-term results of ESS in CRSwNP can be branched in PROMs and other objective measurements. Despite the heterogeneity of reported outcomes make it difficult to perform comparisons and meta-analysis, ESS improves PROMs, including symptoms, QOL and olfaction.

Behçet's disease is a systemic inflammatory disorder of unknown etiology. The disease manifests with diverse clinical symptoms, most commonly recurrent oral and genital ulcers, skin lesions, and uveitis, though it can affect multiple organ systems. Diagnosis is primarily clinical due to the lack of a definitive diagnostic test, and management involves a multidisciplinary approach to control inflammation and manage symptoms.

Background: Obstructive sleep apnea syndrome (OSAS), affecting approximately 1 billion adults globally, is characterized by recurrent airway obstruction during sleep, leading to oxygen desaturation, elevated carbon dioxide levels, and disrupted sleep architecture. OSAS significantly impacts quality of life and is associated with increased morbidity and mortality, particularly in the cardiovascular and cognitive domains. The cyclic pattern of intermittent hypoxia in OSAS triggers oxidative stress, contributing to cellular damage.

Article Synopsis
  • Lemierre syndrome is a rare but serious complication of throat infections, often affecting healthy young adults, and is caused by septic thrombophlebitis of the internal jugular vein.
  • The incidence of Lemierre syndrome is about 3.6 cases per million, with symptoms typically following a pharyngitis infection, leading to potential complications like pulmonary infections.
  • Early diagnosis through CT scans and prompt treatment with broad-spectrum antibiotics are crucial for preventing severe outcomes, as many patients can fully recover with the right therapy.

Objectives: Endoscopic sinus surgery is not a definitive treatment for chronic rhinosinusitis (CRS). The use of sinus stents after surgery to maintain sinus patency and deliver local steroids has gained popularity. The first steroid-eluting bioabsorbable implant (SEBI) approved for this indication, later Propel, was developed in 2011.

Article Synopsis
  • Biologic therapies are new treatments for Chronic Rhinosinusitis with Nasal Polyps (CRSwNP), but it's not clear who they work best for, how much to use, or how long to treat.
  • An AI program was created to help researchers find and analyze studies on these treatments to improve decision-making.
  • Some biologics, like Dupilumab and Mepolizumab, have shown they can help patients feel better, especially those with asthma, but more research is needed to ensure they're safe and effective over time.

Despite the fact that turbinate surgery provides satisfactory results regarding nasal obstruction, most of these procedures are destructive, to some extent, for the respiratory epithelium. There are valid hypotheses suggesting either that turbinate surgery may improve mucociliary clearance (MCC) by improving rhinitis, as well hypotheses suggesting that these surgeries may impair it by damaging the nasal ciliated epithelia. This systematic review is designed with the objective of exploring the effect of turbinate surgery on MCC.
