Medial meatal fibrosis is an uncommon but surgically treatable cause of conductive hearing loss. A review of 10 years experience with this entity at The University of Western Ontario revealed a total of 15 cases involving nine patients. Each of them was treated by one of four otologists. This disease may arise from either recurring or chronic infection or from chronic dermatitis, and it frequently presents with bilateral involvement. It may occur at virtually any age, and to our knowledge, this series includes the first cases of this disease to be described in children. The medical and surgical management of this condition is described in detail and the results are summarized.

Outstanding or protruding ears are relatively common in the pediatric otolaryngology population. We propose a method of otoplasty that is simple to use and provides safe and predictable results. The technique of otoplasty is outlined in detail with emphasis on creation of a desired antehelical fold with the use of modified Mustarde sutures as well as modifications of the lobule and the need for conchal set-back.

Poiseuille's law describes the relationship between pressure and the flow of a gas or liquid of known viscosity through a conduit of known length and radius. In clinical bronchoscopy, resistance varies directly with changes in viscosity of the inspired gas and the length of the bronchoscope. According to Poiseuille's law, resistance varies inversely to the fourth power of the radius of the bronchoscope. Flow-pressure curves were generated for commonly used pediatric Storz-Hopkins bronchoscopes with and without telescopes and the resistance of each system was calculated. Extremely high resistance is encountered with the 2.5 x 20 cm bronchoscope with telescope in place, a fact that most pediatric endoscopists are well aware of. However, comparable resistance is encountered when the 3.5 x 30 cm bronchoscope is used with the telescope in place, a fact not well appreciated by most clinicians.
