RESUMO

<p><b>OBJECTIVE</b>To analyze the therapeutic effect of mastoid surgery for secretory otitis media with mixed hearing loss.</p><p><b>METHODS</b>A retrospective analysis was conducted of the data from 26 cases (43 ears) of secretory otitis media with bone conduction hearing loss collected from 2001 to 2008. Thirty-two ears were treated with mastoid surgery and myringotomy with insertion of ventilation tubes. All the patients received medications after the operation.</p><p><b>RESULTS</b>All the patients showed obvious improvement after mastoid surgery. The average pure tone of air conduction hearing threshold was about 25 dB after the surgery, with the average pure tone of bone conduction hearing threshold of about 15 dB. The patients were followed up for 1-2 years during which no significant change in hearing was recorded, and no middle ear effusion in the tympanic cavity was found after removal of the ventilation tubes.</p><p><b>CONCLUSION</b>Persistent secretory otitis media can be associated with mixed hearing loss, and mastoid surgery can significantly enhance the hearing level to produce positive therapeutic effects.</p>

RESUMO

<p><b>OBJECTIVE</b>To analyze the clinical data of the hearing in otosclerosis patients and explore their association with the clinical manifestations.</p><p><b>METHOD</b>A retrospective analysis of 88 otosclerosis cases (162 ears) was performed. Pure tone audiometry was performed in all the cases 1 to 3 days before the operation for speech analysis at the frequencies of 500, 1 k, 2 kHz and to determined the average pure-tone hearing threshold (PTA) and gas Bone gap (ABG). The incidence of carhart notch was observed in patients with simple conductive hearing loss and mixed hearing loss, and in the early, middle and late stage of otosclerosis.</p><p><b>RESULTS</b>Carhart notch occurred at significant higher incidence in patients with simple conductive hearing loss and in early otosclerosis (P<0.05).</p><p><b>CONCLUSION</b>For common otosclerosis, the lesion invades initially the vestibular window, round ligament and stapes floor, followed by the base of the cochlea, and therefore observation of the carhart notch may help determine the disease course.</p>

RESUMO

<p><b>OBJECTIVE</b>To compare the effects of small fenestra stapedotomy with semiconductor diode laser and microdrill in patients with otosclerosis.</p><p><b>METHODS</b>Twenty-six patients (29 ears) undergoing stapedotomy with semiconductor diode laser and 19 patients (21 ears) with microdrill were compared for the hearing results and complication rates.</p><p><b>RESULTS</b>No statistically significant differences were found in postoperative speech frequency and high frequency pure tone average in closing the air-bone gap between the two groups. The ears treated by stapedotomy with semiconductor diode laser showed significantly better preoperative minus the postoperative air-bone gap and milder dizziness.</p><p><b>CONCLUSION</b>In spite of the good hearing outcomes in both groups, small fenestra stapedotomy with semiconductor diodelaser can achieve better results and reduce the incidence of complications.</p>
