INTRODUCTION Pseudocyst of pinna is an uncommon condition hardly encountered in routine ENT practice. The involvement is usually seen in scaphoid, triangular fossa, and antihelix. Medical treatment is ineffective. Various treatments are suggested in the literature. The aims of the paper were to study the clinical characteristic of patients with pseudocysts and to share our experience with surgi...

BACKGROUND AND OBJECTIVES Keloid scars occur when, compared to normal healing, there is excessive formation of collagen after skin wounds or burns. Different treatments have been tried, though no particular one has been shown to be superior. The objective of this study was to assess the usefulness of the surgical technique originally described as keloid fillet flap in the management of relapsin...

We examined aspects of hearing in the red bat (Lasiurus borealis) related to its use of biosonar. Evoked potential audiograms, obtained from volume-conducted auditory brainstem responses, were obtained in two bats, and the sound pressure transformation of the pinna was measured in three specimens. Field-recorded echolocation signals were analysed for comparison. The fundamental sonar search cal...

Sound pressure transformation properties at the pinna of laboratory mice. Mus domesticus, were studied by measuring the sound pressure level of continuous tone at a series of frequencies at the tympanic membrane as a function of the position of a sound source under free-field stimulation conditions. Sound pressure transformation functions showed some prominent spectral notches throughout the fr...

Different surgical solutions have been proposed for reconstruction of the auricle following loss of the pinna through traumatic injury or neoplastic disease or in patients with congenital defects. Surgical treatment may involve the insertion of an autogenous rib cartilage framework or the use of a porous polymer material inserted into an expanded postauricular flap. Reconstruction with rib cart...

We describe the case of a 4-day-old girl who presented with an epiglottic cyst that was later identified as a rudimentary pinna attached to the soft palate.
