BACKGROUND Many studies have emphasized on fetal pinna measurements and morphologic features to use this structure as an additional marker for fetal chromosomal anomaly. OBJECTIVES To assess relationship between fetal pinna length and gestation age and develop a nomogram. To assess relationship between fetal pinna length and head circumference and biparietal diameter. METHODS Fetal pinna me...

The paper reports a syndrome in which oblique placement of one or both the pinnae on face was found to co-exist with congenital anomalies of heart like VSD, PDA and Tetralogy of Fallot, etc. Although clinically discernible in 90% of the subjects, objective evidence of obliquity of pinna was documented by photogrammetry. The values for the ear inclination in subjects categorized clinically as no...

Since the adoption of some ambiguous and quantitative characters in Flora Republicae Popularis Sinicae 3(1), species identifications of the series Gravesiana have been in disarray, requiring clarification. Two hundred and fifty-nine individuals from 47 different populations were collected for the estimation of morphological characters and phylogenetic analyses. Spores of 26 populations were obs...

We measured the movements of the external ear, or pinna, using the magnetic search coil technique in cats trained to look at auditory and visual targets for a food reward. No behavioral contingencies were placed on pinna movements. Prominent pinna movements accompany eye movements when the animal orients to either auditory or visual stimuli. In visual trials the pinna movements are coordinated ...

OBJECTIVES Otoplasty is a commonly performed surgical procedure that restores the ideal position of the pinna. Although the pinna is a well-recognized component of the auditory apparatus, no studies have assessed the audiological effects of this procedure. We sought to quantify the impact of pinna repositioning on speech intelligibility and reception. METHODS Eighteen adults with normal heari...

Athymic nude (nu/nu) mice were inoculated in the ear pinna with 10(4) p.f.u. herpes simplex virus type 1 (strain SC 16). Initially, the virus was observed to replicate in the pinna, spreading via a neurological route to the dorsal root ganglia, spinal cord, brain and adrenal glands. Following the transfer of lymphoid cells from day 7 herpesvirus-infected hairy immunocompetent donors into infect...

Head-related transfer functions (HRTFs) are essential to the researches of binaural hearing and applications of virtual auditory display. Generally, HRTFs vary with frequency as well as source position relative to head centre. They also depend on anatomical structure and parameters of individual subject. The related anatomical parameters mainly include the dimensions of head and pinnae, and the...

Traumatic injuries of ear range from simple lacerations to complex avulsions and crush injuries. The complicating factors involved are cartilage involvement, poor vascularity of the region and need for high cosmetic satisfaction. Various techniques have been described for reconstruction of earlobe after traumatic injuries. Here, we describe the reconstruction of a partially avulsed pinna using ...
