Balloon Dilation of the Eustachian Tube: A Randomized Controlled Trial with 6 Months Follow-Up.

Background: Obstructive Eustachian tube dysfunction in adults is common. The purpose of this study was to examine whether balloon dilation of the Eustachian tube can improve ventilation of the middle ear among adult patients with mild chronic Eustachian tube dysfunction.

Methods: This study included patients aged ≥18 years with unilateral chronic Eustachian tube dysfunction confirmed with an abnormal tympanometry and a retracted tympanic membrane.

Hearing and Disease-Specific Health-Related Quality of Life in Patients with Otosclerosis after Stapedotomy - a Trial of the SPOT-25 Questionnaire.

Background: The study aims to investigate the effect of stapedotomy on audiology measurements and the disease-specific health-related quality of life for patients with otosclerosis using the Danish Stapesplasty Outcome Test-25 as a quality of life measuring tool.

Methods: In this study, 50 patients who had undergone stapedotomy at our department between September 2017 and December 2020 were included. Data collection was performed by audiometric testing (pure tone and speech audiometry) in the pre- and postoperative settings.

[MRI for middle-ear cholesteatoma diagnostics].

Non-echoplanar diffusion-weighted magnetic resonance imaging (non-EPI-DWMRI) for depicting middle-ear cholesteatoma has a sensitivity as well as specificity at around 90%. It is the accumulated keratin, which results in a high-intensity signal. The detection limit is 3 mm.

Validity and Test-Retest Reliability of the translated Stapesplasty Outcome Test 25 for Measurement of Disease-Specific Quality of Life in Patients with Otosclerosis.

Objectives: To assess the validity and test-retest reliability of the Danish Stapesplasty Outcome Test 25 (SPOT-25) version.

Materials And Methods: The German SPOT-25 questionnaire-consisting of 25 questions within the subscores "hearing function," "tinnitus," "mental condition," "social restrictions," and "general quality of life," found to be significant in terms of health-related quality of life in patients with otosclerosis-was translated into Danish in a three-step process according to the guidelines provided by the International Collegium of Rehabilitative Audiology. In total, 35 patients with otosclerosis were included as cases and 35 individuals without ear-problems as controls.

Validating the 7-item Eustachian Tube Dysfunction Questionnaire in Danish.

Introduction: Eustachian tube dysfunction (ETD) may result in hearing loss, chronic otitis and cholesteatoma. With advances in treatment options, the identification of patients with obstructive ETD is becoming increasingly important. The objective of this study was to validate a Danish translation of the 7-item Eustachian Tube Dysfunction Questionnaire (ETDQ-7).

Extracranial internal carotid artery tortuosity may cause vocal cord palsy.

Background: Clinical practice made us suspect that vocal cord palsy (VCP) can be associated with extracranial internal carotid artery (ICA) tortuosity.

Objectives: To find evidence for a causative relation between ICA tortuosity and VCP.

Methods: This single-center, retrospective study comprised 66 patients with VCP.

[Workup and treatment of Eustachian tube dysfunction in adults].

Symptoms of Eustachian tube dysfunction are frequent and multiple. Therefore, clear definitions and diagnostic criteria are important in order to achieve appropriate patient flow. So far, there has been a lack of consensus on this subject, but the proposed definitions and diagnostic criteria in this review may aid to achieve this.

Large discrepancies in otomycosis treatment in private ear, nose, and throat clinics in Denmark.

Introduction: Otomycosis is a fungal infection of the external ear canal that can involve the middle ear in case of tympanic membrane perforation and also extend to the auricle. Fungi cause 7-15% of external otitis. Diagnosing otomycosis is often based entirely on non-specific clinical signs and symptoms.

Graft take-rates after tympanoplasty: results from a prospective ear surgery database.

Objective: To present a prospective ear surgery database and investigate the graft take-rate and prognostic factors for graft take-rate in tympanoplasty using the database.

Study Design: Prospective database study.

Setting: Tertiary referral center.

Comparison of two bone anchored hearing instruments: BP100 and Ponto Pro.

Objective: This study aimed at investigating if there were differences in auditory performance, operation, or user preference between the Ponto Pro or the BP100, two bone anchored hearing instruments (BAHI) with modern sound processing technology.

Design: Subjects wore the devices in daily life in a crossover study for periods ranging from 25 to 63 days. A speech-in-noise test was carried out as well as measures of noise reduction and feedback suppression algorithms.

Effect of vasoactive intestinal peptide and pituitary adenylate cyclase-activating polypeptide on pancreatic, hepatic and duodenal mucosal bicarbonate secretion in the pig.

Background And Method: The potency of pituitary adenylate cyclase-activating polypeptide (PACAP) and the related vasoactive intestinal peptide (VIP) on pancreaticobiliary and duodenal mucosal bicarbonate secretion (DMBS) was studied in anaesthetized pigs. VIP, PACAP27 and PACAP38 were infused at doses of 250, 500, 1,000, 2,000 and 6,000 pmol/kg x h.

Results: Infusion of VIP in these concentrations increased the portal plasma concentrations of VIP from 9 to 102, 220, 600, 850 and 3,795 pM, respectively.
