Steroid nose drops are used frequently to treat rhinosinusitis and nasal polyposis. The middle meatal area is of key importance in the pathophysiology of these conditions. This study assesses which of three head positions commonly used to instil nose drops resulted in the highest coverage of this area. Discomfort levels were also studied using a visual analogue scale for each position. Five volunteers were studied in: (i) head back (HB); (ii) head forward and down (HFD); and (iii) lying head back (LHB) positions. Betamethasone nose drops, dyed with fluorescein, were instilled into each nostril and the distribution was studied endoscopically. The middle meatus area distribution was highest in the LHB position (55.51%), followed by HFD (31.55%) and HB (6.87%) positions. Comparison of distribution between HB and LHB (P = 0.002) and between HB and HFD (P = 0.045) was statistically significant. The HFD position was most uncomfortable (mean discomfort score 8.8) whereas the HB (2.4) and LHB (2.6) were similar. The LHB would, therefore, appear to be the most suitable position for instillation of steroid nose drops.

Objectives: This study aimed to identify factors predicting postoperative ICU admission, the need for orotracheal intubation (OTI), and the occurrence of supraglottic stenosis in children undergoing supraglottoplasty for laryngomalacia.
Methods: A retrospective analysis was conducted on 31 children (Dear Reviewer, we would have greatly preferred to include a larger sample size. However, as you know, this type of management is rare, and we deliberately selected a 7-year period to ensure a minimum of 30 children while avoiding significant differences in management guidelines over time.

Introduction: Obstructive sleep apnoea (OSA) is characterised by blood oxygen desaturations and sleep disruptions manifesting undesirable consequences. Existing treatments including oral appliances, positive airway pressure (PAP) therapy and surgically altering the anatomy of the pharynx have drawbacks including poor long-term adherence or often involving irreversible, invasive procedures. Bilateral hypoglossal nerve stimulation (HNS) is a new treatment for managing OSA, and this study is intended to determine whether an HNS system is a safe and effective treatment option for adults with OSA.

Background: NSAID-exacerbated respiratory disease (N-ERD) is a hypersensitivity to non-steroidal anti-inflammatory drugs (NSAIDs), such as aspirin or ibuprofen, accompanied by chronic rhinosinusitis (with or without nasal polyps) or asthma. The prevalence of hypersensitivity to NSAIDs is estimated to be 2%. The first line of treatment is the avoidance of NSAIDs.

ECMO is an advanced technology for extracorporeal respiratory and circulatory support. It involves the extraction of venous blood from the patient's body, which is subsequently oxygenated within an oxygenator (or membrane lung). This oxygen-rich blood is reinfused either into veins or arteries, rapidly compensating for impaired lung and heart functionalities.
