- Abstract
Objectives: Vestibular schwannoma (VS) is the most common tumor in the area of the cerebellopontine angle. Depending on tumor size and localization, it may manifest itself in a variety of symptoms, the most common being tinnitus, hearing loss and balance disorders. Material: Retrospective case review of adult patients admitted to single tertiary clinical ENT center were carefully studied. The eligibility criteria were age ≥50 years, diagnosis of unilateral VS confirmed by a magnetic resonance imaging (MRI) and full medical record of a given patient upon diagnosis, including medical interview and hearing evaluation. Methods: Patients were divided into 3 groups according to Koos-Perneczky (KP) scale: first group with tumor size of 0.1--1 cm, second group -- 1.1--1.9 cm and third group -- 2.0--3.0 cm. Statistical analyses were conducted with IBM SPSS v. 24. Results: Based on the eligibility criteria, 19 patients were included in the final analysis (52.6% were men). Based on the KP scale, 63.2% of patients were classi- fied to the first group, 31.6% to the second group and 5.3% to the third group. Tinnitus and hearing loss were observed in all patients (100%). Although all of the patients had unilateral VS, bilateral hearing loss was observed in 31.6% of patients and bilateral tinnitus in 15.8% of patients. Balance disorders were reported by 30% of patients and hyperacusis by 22.2%. None of the patients reported sudden hearing loss or facial nerve palsy. Interestingly, no statistically significant relationship were observed between the tumor size and existence of accompanying symptoms, as well as their severity. Additionally, low specify of the 3 kHz VS screening method according to Saliba, Martineau and Chagnon (2009) was observed, which found application only in 58.3% of patients from the first KP group, 0% of patients from the second KP group and in 100% (1 patient) from the third KP group. Conclusions: Patients with VS can report with a variety of symptoms of different severity, the most common being tinnitus and hearing loss. The current research failed to show the relationship between the presence and severity of clinical symptoms and the size of the tumor.
