OBJECTIVE Canal wall down (CWD) tympanoplasty with soft-wall reconstruction (SWR) is a unique technique for cholesteatoma surgery. The external auditory canal shape after surgery-retracted like a radical mastoid cavity or preserved intact-depends on postoperative aeration in the mastoid cavity. However, the relationship between postoperative middle ear(More)
The effect of cognitive search strategies and variations in the oral environment on discrimination test performance were investigated. Subjects were required to discriminate between low concentration NaCl solutions and water using the 3-AFC and triangle test protocols. As predicted by Thurstonian modeling, subjects obtained a higher proportion of correct(More)
To establish a simple, reproducible procedure for studying facial motor nerve conduction (MNC), we determined the optimal electrode position to record evoked compound muscle action potentials (CMAPs) from perioral muscles in normal subjects. We examined three new electrode positions in which the electrode connected to the one input of the amplifier was(More)
CONCLUSION The novel midline electroneurography (ENoG) method may have advantages over the standard method in terms of ease of electrode setting, and the ENoG value may be a useful prognostic factor. OBJECTIVE We compared ENoG performed in patients with facial palsy using two different methods--the new midline method and standard method--in terms of the(More)
