BACKGROUND Microtia is a congenital deformity of the external ear that occurs in 1 of every 5000 births. Microtia reconstruction using traditional two-dimensional templates does not provide highly detailed ear shapes. Here, we describe the feasibility of using a three-dimensional (3D) ear model as a reference. MATERIALS AND METHODS Seven children aged from 11 to 16 (6 grade III and 1 grade II...

background many clinical and experimental studies have been done to analyze the anatomical and functional aspects of the internal auditory canal (iac) in human beings since there are great inter-individual variability and structural variations that may occur regarding the other adjacent structures. objectives the purpose of this study was to characterize the morphology of the internal auditory ...

background and aim: the double dichotic digit test (ddt) is a simple test for assessing and screening auditory processing system. the purpose of this study was to develope a double ddt, in persian language and find its basic norm values in girls aged 7 to 11 years. methods: the persian version of double ddt is composed of 3 different 25 numerical lists. numbers in each list were recorded dichot...

Ear pain, also known as earache or otalgia, is pain in the ear. The pain that originates inside the ear is called as Primary ear pain or otogenic otalgia. It can be caused by disease in the inner, middle, or external ear, but the three are difficult to distinguish in terms of the pain experienced [1]. If ear pain arises from pathologies in surrounding structures it is called as secondary or ref...

The inner and middle ear are connected mainly through round and oval windows, and inflammation in the middle ear cavity can spread into the inner ear, which might induce a disturbance. In cases with intractable otitis media, attention should also be paid to symptoms related to the inner ear. In this paper, middle ear inflammation and related inner ear disturbances are reviewed with a focus on r...

This paper investigates a new approach for human ear identification using holistic grey-level information. We employ Log-Gabor wavelets to extract the phase information, i.e. ear-codes, from the 1D gray-level signals. Thus each ear is represented by a unique ear code or (phase template). The query ear images are compared with those in the database using Hamming distance. The minimum Hamming dis...

When taking an impression of the external ear canal and ear, the audiologist is engaged in an invasive procedure whereby a foreign body is first placed into the ear canal and then removed. There is always an element of risk for significant medical problems when a clinician is performing an invasive procedure. Although some minor patient discomfort and, at times, some slight trauma to the ear ca...

in order to study of the effect of nitrogen source, operation method and weed control methods on weed biomass, yield and yield components of corn (zea mays l.) an experiment was carried out as split plot factorial based on randomized complete block design (rcbd) with four replications in shahrood university of technology. the treatments included weed control methods at four levels (hand weeding...
