OBJECTIVE: To study a optimal method and pass criterion for newborn hearing screening. METHOD: Transient evoked otoacoustic emissions(TEOAE) was used for hearing screening in 1,277 (2,554 ears) newborns. The pass criterion was defined as signal-noise-ratio(SNR) > or = 3 dB in 3 of 4 frequency bands. RESULT: Pass rates were 89.37%. The best tested time at 2-4 days after birth. CONCLUSION: TEOAE may be an ideal method for newborn hearing screening, SNR > or = 3 dB for frequency bands was the appropriate pass criteria.

With increasing refinement in the surgery of vestibular schwannoma the aims of complete tumor removal and facial nerve preservation have been largely fulfilled. However, the reputation of and place for hearing-preservation surgery still remain uncertain. A major part of this uncertainty is the result of difficulties in interpretation of the various reported results of hearing-preservation surgery. Meaningful comparison between series is difficult because of the varied number of postoperative reporting criteria commonly in use today. Although it is acknowledged that the postoperative reporting criteria affect the hearing-preservation rates, what is not readily appreciated is that preoperative selection criteria for hearing-preservation cases can also significantly affect the success rate of hearing-preservation acoustic neuroma surgery. This article models the many possible outcomes of hearing-preservation schwannoma surgery by use of the previously reported Cambridge series as an illustrative example. With these models some understanding can be gained of the effect of choosing various preoperative and postoperative hearing criteria on the overall hearing-preservation success rate.
