acoustic meatus

External ear was visualized and observations regarding shape, pre-auricular region, external acoustic meatus, anterior surface of each auricle, and earlobe attachment were tabulated.

The control group comprised 46 randomly selected children who came to the pediatric outpatient department with non-ear, nose, and throat (ENT) complaints (e.g., abdominal disorders) and who had no previous history of foreign body in the external acoustic meatus.

Prevalence of collapse and narrowing of the external acoustic meatus when using supra-aural earphones, observed in the study population (N = 436) Observed Condition n Prevalence Bilateral collapse 45 10.3 RE collapse + LE narrowing 5 1.1 LE collapse + RE narrowing 0 -- Bilateral narrowing 36 8.3 RE narrowing + normal LE 6 1.4 LE narrowing + normal RE 3 0.7 RE = right ear; LE = left ear Table 2.

Figure 1 illustrates the determination of Frankfurt's horizontal plane by positioning a stainless steel wire from highest point of the external acoustic meatus to the lowest point of the orbit, parallel to the floor.

Narrowing of the internal and external acoustic meatus (sensorineural loss) and sclerosis of the skull may occur.

All necropsied birds had hemopericardium due to RAR at the point of the junction with the vena cava, and 85% of them had blood in the oral cavity and external acoustic meatus. The vena cava and its caudal branches, the intestinal vessels, and the sinus durae matris and sinus saggitalis were distended.

In lateral view, we registered bullar height (BH, perpendicular length to the plane defined by BL and BW, measured at the dorsal border of the external acoustic meatus).

At end stage, external acoustic meatus become completely obstructed with proliferative granulation tissue.

It was performed visual inspection of the external acoustic meatus, hearing screening and impedance test.

2) with internal auditory acoustic meatus of 8mm and 1cm x 0.8cm on the right with internal acoustic meatus of 9mm (Fig.

Magnetic resonance imaging (MRI) detected an 8-mm enhancing nodule in the right acoustic meatus (figure 1).

The distance from the zygomatic point to the external acoustic meatus, an easily palpable point in the human being, was measured.
