Development of the "LAser Surgical skills Evaluation for Residents" (LASER) Scale Through a Modified Delphi Method.

Background: The CO laser is frequently used during microlaryngeal surgery (MLS) for a variety of pathology including laryngeal malignancy and stenosis. Learning how to use the laser safely is part of the curriculum for every otolaryngology resident. However, assessment of laryngoscopy technical skills can be challenging for supervisors, making it difficult to adequately provide feedback to trainees.

A Randomized Controlled Trial on Facial Muscle Therapy in Nasal Obstruction.

Muscular exercises of the lateral nasal wall have been described as a potential treatment of nasal valve obstruction. The objective of this study was to compare whether nasal exercises improve nasal obstruction, using a randomized controlled model. Participants were randomized into groups performing exercises targeting nasal (group A) or facial (group B) muscles.

Chronic suppurative otomastoiditis due to nontuberculous mycobacteria: A case series.

Introduction: Eight new cases of chronic otomastoiditis due to nontuberculous mycobacteria were reported at Center Hospitalier Universitaire Sainte-Justine (CHUSJ) between 2008 and 2018. In the literature, only 89 cases have been described since 1972. This case series aims to define the clinical presentation, infectious pathogens, as well as diagnostic and therapeutic means employed in cases of nontuberculous mycobacteria otitis media encountered in our tertiary pediatric reference center.
