(1) Objective:To analyze the characteristics of anomalies of chorda tympani nerve.

(2) Objective To investigate the ultrastructure of the chorda tympani nerve and analyze the taste and facial nerve functions in patients with cholesteatoma.

(3) To demonstrate the effect of chorda tympani nerve used in tympanoplasty.

(4) Single nerve fiber recording from the ear's chorda tympani show that same lack of specificity.

(5) Different responses of nerve fibers in chorda tympani to quinine HCl and PTC were found, having the same bitter.

(6) He recorded the firings of many chorda tympani fibers in response to the ingestion of different salts.

(7) The tympanic segment of chorda tympani nerve is parallel with the tympanic segment of facial nerve.

(8) The resection of chorda tympani nerve can cause taste blindness of the right side of tongue.

(9) Pyramidal eminence and chordal eminence should not be lowly abraded in order to avoid damaging the musculus stapedius and chorda tympani nerve when dealing with a facial recess lesion.

(10) In most cases other adjuvant methods, for example, scute repairing, chorda tympani nerve tightening prosthesis, etc , had been used.

(11) The degree of valvular regurgitation was not related with the range of prolapse and was related with the severity of tendinous chorda injury.

(12) Differences in the amount of saliva secretion and histologic appearance were compared based on the existence of chorda tympani branches in the allograft. RESULTS.

(13) Objective:To provide the correlative surgery data by the anatomical study of chorda tympani nerve.
