[Current diagnostics and therapy in chronic rhinosinusitis]. / Aktuelle Diagnostik und Therapie der chronischen Rhinosinusitis.

INTRODUCTION: Chronic rhinosinusitis is a prevalent condition with significant implications for both patients and society at large. The diagnostic and treatment approaches are primarily guided by the EPOS2020 guidelines in Europe, which increasingly delve into the molecular -mechanism of the disease and its resulting phenotypes. In recent years, biologics have emerged as a promising option, in particular for cases that are refractory to conventional therapies. However, the management landscape has become more intricate, necessitating consideration and potential concurrent treatment of comorbidities. Moreover, the utilization of biologics is accompanied by substantial costs, warranting personalized assessment for each patient. Hence, the establishment of specialized boards comprising clinicians from diverse disciplines to collaborate on treatment recommendations is imperative.

Chondrosarcoma of the petrous apex with nerve abducens involvement in a woman with pre-existing contralateral amblyopia.

We report about a case of a woman in her 50s with a chondrosarcoma of the petrous apex. She has a strabism due to a right-sided amblyopia since childhood and noticed a slowly progressive squint angle in the last months. Her general practitioner (GP) referred her to an ophthalmologist who diagnosed a left abducens paresis and initiated an MRI demonstrating a mass in the left petrous apex. A transnasal endoscopic transsphenoidal biopsy revealed a grade I chondrosarcoma. The patient underwent an endoscopic transsphenoidal anterior petrosectomy approach with complete removal of the tumour. After surgery the squint angle gradually improved to previous levels, so that the patient was able to resume her work. This report demonstrates that even slight changes of a squint angle without diplopia, in this case because of pre-existing amblyopia, could be a hallmark of an intracranial process.

Conductive Hearing Loss with Age-A Histologic and Audiometric Evaluation.

A retrospective analysis to quantify age-related changes of the incudo-malleolar joint (IMJ) and incudo-stapedial joint (ISJ), and to analyse changes in the air-bone gap (ABG) with age, was performed. Defined histologic parameters of 153 IMJ and 106 ISJ from subjects aged from birth to 70 years were correlated to age. Additionally, audiograms of 1760 ears of 974 other subjects aged 20 to 80 years were retrospectively analysed and the ABG was correlated to age. The joint space (age group from 0 to 10 compared to 61 to 70 years) became significantly wider with age (IMJ: from a mean of 44 µm to 100 µm, p < 0.001; ISJ: from a mean of 28 µm to 69 µm, p < 0.009. The thickness of cartilage of the incus decreased in the first 20 years of life (IMJ, from a mean of 88 µm to 65 µm, p < 0.01; ISJ: from a mean of 44 µm to 35 µm, p < 0.01). The ABGs of younger ears (20-40 years) was significantly larger at 500 Hz compared to older ears (60-80 years) by 2-4 dB, while it was significantly smaller by 3-5 dB at 4000 Hz (p < 0.0017). Interindividual variations in all age groups were large for both analyses. The increased joint spaces could potentially reduce the stiffness in the joints and explain the increase in ABG at 4000 Hz and the drop at 500 Hz. While the average change is small and of minimal clinical relevance, a larger increase of ABG with age is seen in some subjects.
