Among the many existing hearing problems, there are those that need to be corrected through the replacement of the ossicles of the middle ear with a prosthesis. The type of the prosthesis used in the rehabilitation of the middle ear, total ossicular replacement prosthesis (TORP) or a partial ossicular replacement prosthesis (PORP) depends of the level of the ossicular impairment [1,2]. In the p...

We describe a case of an 81-year-old patient, where we used a new technique for the reconstruction of postauricular defects (of 3 x 4 cm diameter). The swallowtail flap is an advancement flap that allows getting beyond the repair of the defect, providing an excellent aesthetic result because the scar is masked in the neck and retroauricular folds and does not alter the shape and projection of t...

In this paper we report the development of a micro screw pump for discharging effusion from middle ear for treatment of otitis media. This tool extrudes effusion using a newly designed screw, which rotates at 90,000 rpm in a pipe penetrated through tympanic membrane. This tool satisfies the discharge performance especially for high viscosity effusion while it has smaller diameter such as about ...

In the amphibian embryo, beginning in the late neurula and continuing through midtailbud stages, the developing medulla exerts an inductive influence on the prospective ear, effecting its determination. Fine structural analysis of the region of closest apposition between the two tissues in the axolotl (Ambystoma mexicanum) revealed that during this period, there is a significant increase in the...

BACKGROUND Articular cartilage has been the focus of multiple strategies to improve its regenerative/ repair capacity. The Murphy Roths Large (MRL/MpJ) "super-healer" mouse demonstrates an unusual enhanced regenerative capacity in many tissues and provides an opportunity to further study endogenous cartilage repair. The objective of this study was to test whether the super-healer phenotype coul...

The use of mulch in the soil attenuates saline stress corn plants. objective this study was to evaluate effect irrigation with brackish water under different plant mulches on productive performance corn. carried out field conditions, at Piroás experimental farm Universidade da Integração Internacional Lusofonia Afro-Brasileira, UNILAB, Redenção, Ceará, Brazil, from August November 2020. design ...

A field experiment was carried out in Al-Hajjaj district- Salah Al-Din Governorate, during the autumn season of 2021. The experimental design randomized complete block (RCBD) three replications. It had ABA concentrations 0, 9 and 12 mg L-1 that sprayed on plants at 4 8 leaves beginning flowering. Results indicated a concentration superior shortening number days from sowing until 50% tasseling (...

Keywords: enlarged endolymphatic duct and sac syndrome; sudden hearing loss; retrocochlear pattern Abstract: Enlarged Vestibular Aqueduct (EVA) is one inner ear malformation found in 35% of children with unilateral sensorineural hearing loss.(1) Case reports of late diagnosis of enlarged vestibular aqueduct in young adulthood are extremely rare. The authors present a case of unilateral sensorin...

The current study reexamined the effect of vent diameters on objective and subjective occlusion effect (OE) while minimizing two possible sources of variability. Nine hearing-impaired participants with primarily a high-frequency hearing loss were evaluated. Laser shell-making technology was used to make ear inserts of completely-in-the-canal (CIC) hearing aids for the study. This was to minimiz...
