Evolution of sinonasal clinical features in children with cystic fibrosis.

Objective: to assess the evolution of sinonasal manifestations in children with cystic fibrosis, since the improvement of their prognosis over the last decades.

Methods: an observational, monocentric study with a retrospective cohort. We included 173 children (from 4 to 18 years old) with cystic fibrosis followed at the pediatric cystic fibrosis center of lyon, france.

Microbiology and antibiotic therapy of subperiosteal orbital abscess in children with acute ethmoiditis.

Objective: The objective of this study was to investigate the microbiological cultures and the management of acute ethmoiditis complicated by subperiosteal orbital abscess (SPOA) in a pediatric population.

Methods: The medical records of children under 18 years old was performed in a tertiary referral pediatric center from January 2009 to April 2017. Clinical examination, computed tomography scans, medical and surgical treatments were reviewed and compared to other studies in literature.

Does Checking the Placement of Ossicular Prostheses via the Posterior Tympanotomy Improve Hearing Results After Cholesteatoma Surgery?

Introduction: Posterior tympanotomy (PT) is often performed during the surgical management of middle ear cholesteatoma with extension in the retrotympanum area. This PT can also be used to control the right position of the ossicular prosthesis masked by the tympanic membrane reconstruction.

Objective: To compare audiologic results after ossiculoplasty performed via the outer ear canal and via the PT for patients with cholesteatoma.

Bone quality and biomechanical function: a lesson from human ossicles.

In humans, the middle ear contains a chain of three ossicles with a major highly specific mechanical property (transmission of vibrations) and modeling that stops rapidly after birth. Their bone quality has been rarely studied either in noninflammatory ossicles or in those from ears with chronic inflammation. Our primary goal was to assess bone microarchitecture, morphology and variables reflecting bone quality from incuses, in comparison with those from human femoral cortical bone as controls.
