Patterns of Hearing Loss in Irradiated Survivors of Head and Neck Rhabdomyosarcoma.

Purpose: The frequency and patterns of HL in a HNRMS survivor cohort were investigated. A dose-effect relationship between the dose to the cochlea and HL was explored.

Methods: Dutch survivors treated for HNRMS between 1993 and 2017 with no relapse and at least two years after the end of treatment were eligible for inclusion.

Prevalence of chronic rhinosinusitis in the general population based on sinus radiology and symptomatology.

Background: The prevalence of chronic rhinosinusitis (CRS) measured in epidemiologic studies is 5% to 12%. This might be an overestimation because of overlap with other diseases, such as allergic rhinitis.

Objective: We aimed to calculate the prevalence of CRS using a combination of epidemiologically based CRS according to the European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS) together with sinonasal opacification on imaging.

Mucocele formation after frontal sinus obliteration.

Background: A possible complication of frontal sinus obliteration with fat is the formation of mucoceles. We studied the prevalence of mucoceles as well as and the need for revision surgery.

Methods: Retrospective case review of forty consecutive patients undergoing frontal sinus obliteration from September 1995 to February 2012 for chronic rhinosinusitis (26), frontal mucocele (12) or frontal osteoma (2) with an average follow up of 80 months (range 15-218).

Chronic orbital inflammatory disease and optic neuropathy associated with long-term intranasal cocaine abuse: 2 cases and literature review.

Orbital inflammatory disease and secondary optic neuropathy is a rare but devastating complication of long-term intranasal cocaine abuse. We describe 2 patients with a history of intranasal cocaine consumption who presented with subacute onset of unilateral vision loss from optic neuropathy and limitation of abduction in the affected eye. Magnetic resonance imaging findings included an orbital mass in combination with absent nasal septum and partial destruction of the paranasal sinuses.

Staging and follow-up of high-grade malignant salivary gland tumours: The role of traditional versus functional imaging approaches - A review.

Following up on the Consensus Conference on high-grade malignant salivary gland tumours (HGMSGT) in adult patients in Brescia, Italia, in October 2014, we review the current imaging modalities for diagnosing and staging these rare tumours. The advantages of functional MR imaging techniques such as diffusion weighted imaging (DWI) and dynamic contrast-enhanced MR imaging (DCEMRI) in comparison with traditional MRI will be outlined. The limited role of (18)FDG-PET CT and fMRI will be addressed.
