BACKGROUND AND PURPOSE: The aim of the present prospective study was to verify the specificity of non-EPI DWI-MRI in patients operated for middle ear CHO who showed positivity at imaging performed 6 to 9 months after surgery and underwent second-look surgery. MATERIALS AND METHODS: All patients underwent 1.5-T non-EPI DWI-MRI 6 to 9 months after surgery: those showing a hyper-intense signal in the middle ear underwent a revision surgery, whilst the others are still under radiological follow-up and were not considered in this study.

OBJECTIVES: To assess and monitor lateral semicircular canal (LSC) function over time in patients affected by chronic otitis media with cholestea- toma (CHO) complicated by fistula of LSC (LSC-F) before and after surgery using video Head Impulse Test (vHIT).

Objective

To evaluate the feasibility and efficacy of a new high-resolution 3D endoscope in endoscopic ear and lateral skull base surgery.
Methods

Purpose Compare the outcomes of primary exclusive endoscopic ear surgery with those of the microscopic ear surgery in a group of patients affected by attic cholesteatoma. Materials and methods Eighty patients suffered from attic cholesteatoma. Forty patients surgical treated with endoscopic ear surgery and forty patients surgical treated with microscopic ear surgery.

In this previous study, we compared exclusive endoscopic ear surgery (EES) withmicroscopic earsurgery (MES) in the surgical treatment of a series of‘attic’cholesteatomas.Clarifications in response to some observations made by Zhengcai-Lou et al. are reported below. In the study conclusions, the authors did not indicate the EES as theoptimal treatment in cases of‘attic’ cholesteatoma.

Objectives: the aim of this paper is to study the incidence of facial canal dehiscence (FCD) in pediatric and non-pediatric patients, analyzing eventual differences in frequency, localization, primary or revision surgery and duration of the disease. Methods: 527 patients suffering from chronic otitis media with acquired cholesteatoma, divided into two groups, those aged 18 years or over (470 patients), and those aged below 18 years (57 patients). Results: Total incidence of FCD in adult population was 25,7% (121/470) and 7% (4/57) in pediatric one.

Bone erosion is considered a typical characteristic of advanced or complicated cholesteatoma (CHO), although it is still a matter of
debate if bone erosion is due to osteoclast action, being the specific literature controversial. The purpose of this study was to apply a
novel scanning characterization approach, the BSE 3D image analysis, to study the pathological erosion on the surface of human
incus bone involved by CHO, in order to definitely assess the eventual osteoclastic resorptive action. To do this, a comparison of
