To analyze the short-term and long-term effect of Er-yttrium aluminum garnet (Er-YAG) laser in stapes surgery.There were 86 patients operated by the Er-YAG laser stapedotomy from 2001 to 2007 were analyzed retrospectively, with 23 male, 63 female and 13 double ears and with the average age of 48 years old, ranging from 12 to 78. All of 99 ears suffered deafness of conduction. The average air-bone-gap (ABG) of all patients before surgery was (37.4+/-9.0) dB HL (ranging from 13.7 to 58.7 dB). The patients followed-up over 6 weeks after the surgery was regarded as the short-term result, while over one year follow-up as the long-term effect (according to the standard of the Committee on Hearing and Equilibrium of the American Academy of Otolaryngology-Head and Neck Surgery). The followed-up average time was (26.3+/-15.8) months (range from 14 to 73 months). The pre-post-operation average bone conduction auditory threshold of 2 kHz and 4 kHz were observed. The data of the patient whether or not has the symptoms of tinnitus and dizzy and the lasted days were also recorded.After surgery, short-term ABG of 99 ears was (15.7+/-8.7) dB, matched-pairs t test with the numbers of before surgery, t=22.79, P0.01. The results of 45 ears (45.5%) with ABG10 dB or air conduction improved more than 30 dB were regarded as excellence. The air conduction of 88 ears (88.9%) improved more than 15 dB was regarded as utility. With 82 ears (82.8%) followed-up more than 1 year, the average ABG was (11.7+/-6.8) dB, matched-pairs t test with the numbers of before surgery, t=23.37, P0.01, compared with the short-term visit result [(15.3+/-9.2) dB, 82 ears], t=4.82, P0.01, both of which were considered statistically extremely significant. Among them, 50 ears (61.0%) have the excellent effect while 74 ears with (90.2%) ABG20 dB. The average bone conduction auditory threshold in 2 kHz was (34.5+/-15.0) dB before surgery, matched-pairs t test with short-term visit result (33.4+/-15.9) dB, t=1.96, P=0.026 14, with long-term visit result (32.7+/-15.2) dB, t=3.24, P=0.000 87, all of which had the significant difference, manifest that the Cohort's notch had been improved after the surgery. The data of bone conduction auditory threshold of 4 kHz with long-term following-up result matched-pairs t test with that of surgery before, t=0.76 (P0.05), which showed the change of the bone conduction had no statistics difference. There were 55 ears had the persistent tinnitus before surgery, in which 42 ears (76.4%) with no the tinnitus, 13 ears with same to that of preoperative, and 3 ears (3.0%) with remaining tinnitus after surgery but who had not it preoperation and all disappeared after 2 - 3 days. There were 12 ears (12.1%) with light dizzy after surgery, but their live could deal with himself and the average dizzy lasted 2.3 days.Er-YAG laser stapes surgery is safe to the inner ear, and it primal free from the imminent risk in stapes surgery, so the effect can be affirmed.

To assess the results of multi-technique with intact canal and scute rebuild operation for middle ear cholesteatoma.Analysis of 113 cases (males 60, females 53, with mean 42.7 years old), of which with double ears of 11 cases, and totally 124 ears (11 ears for one review, an ear for third time review, and totally 137 operations) was retrospectively performed. Ten cases less than 19 years old were operated from September 2001 to January 2006 for middle ear cholesteatoma as well as ossiculoplasty with intact canal and scute rebuild etc multi-technique. All cases were followed up for a mean (36.58 +/- 20.47) months.There were 118 ears (95.2%) without cholesteatoma recurrence. Six ears were found cholesteatoma recurrence. Other 6 post-operation ears with drum re-perforation and hearing drop were re-operated. The pre-operation air-bone gap (ABG, average of 0.5, 1, 2 kHz) of 124 ears, with in initial 112 ears, was (33. 61 +/- 12.35) dB, while that of post-operation ABG was (13.58 +/- 9. 27) dB, by partnership t test, t = 18.35, P0.01. The pre-operation ABG in reviewed 12 ears at the first pre-operation was (38.83 +/- 12.43) dB, but post-operation ABG (10.38 +/- 8.99) dB, by partnership t test, t = 5.38, P = 0.00022. The ABG closure to within 20 dB was tested in 100 ears while ABG over 20 dB but air conduct (AC) in 40 dB was in 6 ears, and then as succeed was in 106 ears (85.5%). ABG closure within 10 dB was in 50 ears and though ABG over 10 dB but ABG reduced over 30 dB was in 9 ears (59/124, 47.6%) as which as best result. Bone conduct (BC) threshold was tested of 21 ears (16.93%) with raise 1-9 dB, of 42 ears (33.9%) with no change and of 61 ears (49.2%) with descend 1-28 dB. Of 10 cases less than 19 years old post-operation ABG was (8.80 +/- 5.27) dB, which indicated that all cases was as succeed.Using intact canal and scute rebuild etc multi-technique a normal canal, hearing improvement and very low recurrent could be gained for middle ear cholesteatoma, especially in juvenile and children. The multi-technique should be almost no damage for hearing bone conduct.

To assess the effect of stapes surgery on advanced otosclerosis (AO).In 300 cases randomly collected of otosclerosis in 1970 to 1999, 68 cases (77ears) were selected for retrospective analysis, which met the criteria of advanced otosclerosis (mixed deafness, with bone-conduction levels exceeding 40 dB and air-conduction levels exceeding 70 dB in 500 - 2000 Hz).The air-conduction of sixty-eight cases (77 ears) were from 77.32 dB to 53.7 dB (500-2000 Hz) after operation, mean decreased 23.62 dB. Of 71 ears (92.21%) obtained air-conduction improved over 10 dB, of 46 ears (59.74%) gained A-B Gap closure in 10 dB. Air-conduction were from 79.01 dB to 58.23 dB (500 - 4000 Hz) after operation and mean decreased 20.78 dB. Of 68 ears (88.31%) obtained air-conduction improved over 10 dB, of 32 ears (41.56%) gained A-B gap closure in 10 dB. After followed up 5-25 years, of 67 ears were retained stabilization, of 28 ears obtained more improve than postoperation. But 4 ears had drop (all was stapes-elevation and re-improvement after them was reviewed).Stapes surgery is effective operation to cured otosclerosis, advanced otosclerosis or far-advanced otosclerosis had greater help to improved hearing.

To evaluate the curative effects of Betamethasone for treatment of voice hoarseness of chronic hypertrophic laryngitis.From July, 2001 to December, 2002, 48 cases of the chronic hypertrophic laryngitis had been treated by injected of Betamethasone at vocal cords. Fundamental frequency (FO), jitter, shimmer, normalized noise energy (NNE) acoustics' parameters were tested and paired t test were calculated. The voice quality of 1 month and 6 months after treatment were synthetically graded, one-way ANOVA and the DANCAN test were conducted.Eight cases were injected under surface anesthesia with indirect laryngoscopy at the clinic service. Thirty-eight cases were injected under general anesthesias with micro-laryngoscopes. After six months following up, the voice hoarseness was obviously improved, the congestion or oedema of vocal cord was lessened, and the voice quality was improved as well. The results of F0, jitter, shimmer, NNE acoustics' parameters after treatment 6 months showed: 8 of 48 cases (17.39%) had treatment effect, 22 out of 48 cases (47.83%) had obviously effect, 10 out of 48 cases (21.74%) had cured. The total effectiveness had reached 86.96% (40 of 48 cases). Six of 48 cases (13.04%) was failure.Vocal cord injection of Betamethasone for the hoarseness of chronic hypertrophic laryngitis is an effective treatment method.

To assessment result with multi-measures operation for adhering otitis media.A retrospective review of 108 cases (male 45, female 63), double ears 12, all was 120 ears. Of 20 ears had been radical operated for cholesteatoma some years ago. Of 46 ears had incorporate cholesteatoma now. Of 54 ears had only adhering in middle ear but no had been radical or incorporate cholesteatoma who underwent operation from January 1999 to May 2003 for chronic ear disease as well as ossiculoplasty with multi-technique measures (for example auto-bone cup-pole or gung-pole as total and partial ossicular replacement prostheses; scute rebuild by auto-bone; absorbable Metrogel; tympanic chorda nerve as a spring press prostheses etc) were used in operation, and were followed up mean (26.11 +/- 11.31) months (range 12 approximately 53 months).One hundred and twenty ears mean AB gap was (38.60 +/- 12.70) dB pre-operation. It was (15.28 +/- 11.69) dB post-operation. Partnership t test, t = 21.24, t 0.01 = 2.6021.24, P0.01. The air-bone gap (AB gap) closure to within 20 dB as succeed achieved in 70% (84 ears). AB gap closure in 10 dB as best result in 40% (48 ears). Air conduction was under 40 dB in 70% (83 ears). AB gap closure not enough 10 dB and Air conduction over 40 dB as no effect was 6% (7 ears) .As long as technique measures is right, even though adhering middle ear had much difficult in operation, it still can gain succeed to 70%. But had still 30% no succeed, more study is necessary.
