Photograph when crying (figure 1)
1. Asymmetric face
2. Difficult closing of left eye
3. Paralysis of left side of the mouth.
4. From above findings, left side peripheral facial palsy is considered.

Photograph (3 m/o) (figure 2)
1. Similar finding as figure 1

Otoacoustic emissions (OAE) (figure 3)
1. Downward displacement of left ear results (red arrows) below
   normal lower limit (normal range between blue arrows), suggesting
   abnormal function of outer hair cells in left cochlear.
2. Normal right ear results (green arrows) between normal range.

Auditory brainstem response (ABR) (figure 4)
1. Poor morphology of left side with loss normal V wave in left side,
   suggesting sensorineural hearing impairment.
2. Normal right side for comparison. Normal V waves (arrows).

Low dose multidetector row CT scan of temporal bone with
 multiplanar reconstruction, and without intravenous contrast
 (figure 5 and 6):

1. Increased opacity in left middle ear cavity and left mastoid air
   cells, may due to otitis media and mastoiditis.
   Less possibility: middle ear soft tissue mass.
2. Very small caliber of the orifice of left internal auditory
   canal in vertical diameter (arrow in figure 6), suggesting
   congenital hypoplastic internal auditory canal and possibly
   associated sensorineural hearing impairment, peripheral facial
   nerve palsy, or dizziness and tinnitus.
