According to Helmholtz's Square illusion, a square appears wider when it is filled with vertical lines and higher when filled with horizontal lines (Helmholtz von, 1866). Recently, Pinna (2010a) demonstrated that the grouping of small squares on the basis of the similarity principle influences also perception of their shape and of the whole emerging shapes. The direction imparted by grouping is...

In this article, a beamformer is proposed as a functional model for the spatial and temporal filtering characteristics of the external ear. The output of a beamformer is a weighted combination of the data received at an array of spatially distributed sensors. The beamformer weights and array geometry determine its spatial and temporal filtering characteristics. A procedure is described for choo...

Ear cartilage piercing is becoming common; hence family physicians will be encountering problems with this fad. It is important that we determine the best approach to deal with infections resulting from ear cartilage piercings. While most of us consider Staphylococcus aureus to be the primary infecting agent, it is not uncommon for cartilaginous ear piercings to become infected with Pseudomonas...

The directional properties of bat ears as receivers is a current area of interest in ultrasound research. This paper presents a new approach to analyse the relationship between morphological features and acoustical properties of the external ear of bat species. The beam pattern of Rousettus leschenaultii's right ear is measured and compared to that of receiver structures whose design is inspire...

A case of recurrent hidradenoma of the external ear with intracranial spread is described. The presentation, classification and management of this rare tumour are discussed and the importance of adequate long term review is stressed.

BACKGROUND Ventilation tube insertion is a common treatment for children with persistent otitis media with effusion. Parents are concerned about the morbidity of this procedure and the influence of ventilation tubes on daily activities. Permissibility of swimming is a question that is most often asked. The aim of this study was to investigate the possibility of water penetration through ventila...

UNLABELLED Human temporal bones in teaching ear surgery are rare. The lamb's temporal bone might be a possible alternative. MATERIAL AND METHODS Temporal bones of the lamb were dissected with a typical temporal bone lab drilling program. We included a mastoidectomy, endaural approaches, but also analyzed the outer appearance, the external ear canal and the hypotympanon. Some steps differed fr...

BACKGROUND Idiopathic inflammatory medial meatal fibrotizing otitis (IMFO) is rare. Only a few cases with unknown cause have been reported. OBJECTIVE To report 3 cases of IMFO as a specific diagnostic entity. PATIENTS AND METHODS Two adults and 1 child with bilateral IMFO were observed for several years at the Department of Otorhinolaryngology of Helsinki University Hospital, Helsinki, Finl...
