Despite the declining incidence of acute mastoiditis (AM) due to antibiotics, complications persist, necessitating surgical intervention in severe cases. Recent studies suggest conservative treatments, avoiding mastoidectomy, show high recovery rates. However, this trend raises concerns about severe complications, prolonged treatment, increased antibiotic use, and declining surgical skills. While much research focuses on AM pathogenesis and treatment, the long-term consequences, especially post-mastoidectomy ear function, are less understood. To address this, we studied the permanent effects of surgically treated AM and mastoidectomy on ear function.

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).

Nasal breathing (NB) is a fundamental physiological process, and emerging research indicates its potential role in modulating resting metabolism, impacting energy expenditure and metabolic efficiency. This study investigates the impact of NB on resting metabolic rate (RMR), offering novel insights into metabolic regulation.

To report our institution's experience with patients who underwent subtotal petrosectomy (STP) for refractory ear disease who are candidates for cochlear implant (CI) and to highlight simultaneous STP with CI its advantages, surgical outcomes, post-operative complications management, and considerations for staging a procedure.

Our study aimed to assess the reliability of screening tests in healthy newborns across diverse hospital environments and neonatal intensive care unit (NICU) infants hospitalized for over 5 days, particularly within the framework of hearing screening in developing countries.

The purpose of this study was to evaluate the effect of menstrual cycle phases on the vestibular system in healthy adult women.

In vestibular implants (VI), the electrode position is thought to be important for optimal neural activation. The objective of this study was to evaluate the stability of the vestibular electrode position over time.

To conduct an updated meta-analysis evaluating the efficacy and safety of tranexamic acid (TXA) versus control during endoscopic sinus surgery.

Primary stapes surgery is considered a challenging intervention in ear surgery. Despite an risk of deafness in 0.5-1 percent, this procedure has still a good benefit-risk ratio due to the improvement in hearing and quality of life that is usually achieved. However, revision after prior stapes surgery is considered even more challenging. Revisions after stapes surgery are very heterogeneous procedures, both in terms of the indication and the surgical strategy and are generally considered to be significantly more demanding. Reasons for complications after prior stapes surgery as well as strategies for successful revisions are not well described in the literature.

To explore the links of leisure-time physical activity (LTPA), and occupational physical activity (OPA) with allergic rhinitis (AR) and chronic rhinosinusitis (CRS) in a nationally representative sample of the Korean population.

This study analyzed the immunoexpression of C-X-C chemokine ligand 12 (CXCL12) and C-X-C chemokine receptor 4 (CXCR4) in oral tongue squamous cell carcinoma (OTSCC) of young (≤ 45 years) and older (≥ 60 years) patients and correlated the findings with clinicopathological parameters (sex, tumor size, regional metastasis, clinical stage, and histopathological grade of malignancy).

The success of partial ossicular chain reconstructions in cases of conductive hearing loss depends on many factors. One important factor is the coupling between the prosthesis and the stapes head, which has not been explicitly investigated previously. Prostheses with different forms of attachment to the stapes are available, namely clip and bell type PORP. We present a standardized method to assess the quality of the prosthesis-stapes connection. The coupling quality of different prostheses is compared using measurements on a specimen model.

Obstructive Sleep Apnea (OSA) is a prevalent sleep disorder linked to increased risks of cardiovascular and metabolic disorders, significantly raising overall mortality rates. This study explores the associations between OSA and mortality in adults with and without Metabolic Syndrome (MetS) using data from the National Health and Nutrition Examination Survey (NHANES).

To investigate the associations between fasting blood glucose (FBG) and type 2 diabetes mellitus (T2DM) and the risk of postoperative CRS recurrence.

To assess the opinion, practices, and challenges of international key opinion leaders about two minimal invasive surgical techniques in supraglottic laryngeal tumours: transoral laser microsurgery (TLM) and the transoral robotic surgery (TORS).

Different surgical techniques exist for treating cholesteatoma, such as microscopical or transcanal endoscopic ear surgery (TEES). This study aimed to compare these two techniques, focusing on quality of life.

The T-tube poses significant challenges for positive pressure ventilation.

Despites a tripling of recognised occupational sinonasal adenocarcinomas in the past three decades, no comprehensive publications of the epidemiological development and histological distribution of sinonasal malignancies exist in Germany. Therefore, this study aims to analyse population-related data and address gaps in the nationwide cancer registry.

Skull base osteomyelitis is a rare but potentially life-threatening disease. It usually occurs as a complication of severe otitis externa or infection in the nasopharynx, often in immunocompromised patients. The therapeutic strategy is complex, patient-specific and requires interdisciplinary cooperation.

The sphenoid sinus features many anatomical variations between individuals from different populations in the world. The understanding of these variations is important for the surgeons to plan for surgeries which involve intervention through the nasal approach. The aim of the present systematic review was to perform a qualitative synthesis of available studies which assess the effect of sphenoid sinus (SS) anatomical variations on the outcomes of endoscopic endonasal transsphenoidal surgeries (ETSS).

This study aimed to investigate the efficacy and safety of coseasonal initiation of Artemisia annua sublingual immunotherapy (SLIT) for children and adult patients with allergic rhinoconjunctivitis (ARC).
