Impact of upper airway expansion surgery on the blood pressure of hypertension patients with upper airway obstruction / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To explore the impact of upper airway expansion surgery on the blood pressure of hypertension patients with upper airway obstruction.@*METHOD@#Clinical data of 45 cases of hypertension patients with nasal obstruction who were underwent upper airway expansion surgery. The morning sitting blood pressure of patients were recorded. All of the patients were underwent nasal expansion surgery and 11 cases with obstructive sleep apnea hypopnea syndrome were combined with H-uvulopalatopharyngoplasty.@*RESULT@#Blood pressure of all 45 cases were apparently reduced in 12 months after the operations [systolic blood pressure (157.38 +/- 15.15) mmHg to (132.18 +/- 8.43) mmHg, diastolic blood pressure (95.42 +/- 9.28) mmHg to (82.31 +/- 5.88)mmHg], in which 9 cases with type I hypertension were lowered to normal pressure. Results had statistical difference between pre-operation and post-operation (P < 0.01).@*CONCLUSION@#Upper airway expansion surgery (including nasal and pharynx cav ity) can help lower blood pressure of hypertensive patients with nasal obstruction. Post-operative results were better than H-uvulopalatopharyngoplasty only.

Influence of childhood obstructive sleep apnea-hypopnea syndrome on hearing / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To explore the influence of hypoxemia on the hearing of children with childhood obstructive sleep apnea-hypopnea syndrome (OSAHS).@*METHOD@#Auditory brainstem response (ABR) and distortion-product otoacoustic emission (DPOAE) was recorded in 68 ears and 60 ears respectively of children suffering from OSAHS with "A" tympanogram. Meanwhile, ABR and DPOAE was also recorded in 30 controls of children with "A" tympanogram.@*RESULT@#There was no statistical difference between the mild OSAHS group and the control group in the latency of wave I, III and V, the interval between wave I and III, III and V, I and V. There was significant difference between the moderate and severe OSAHS group and the control group in the delayed latency of wave I. There was significant difference between the mild OSAHS group and the control group in the amplitudes of DPOAE at 8 kHz. There was significant difference between the moderate and severe OSAHS group and the control group in the amplitudes of DPOAE at 6 kHz and 8 kHz.@*CONCLUSION@#Cochlear function was affected when AHI > or = 10/h. ABR and DPOAE could be used to detect the early damagement of auditory function in childhood OSAHS.

Relationship between childhood obstructive sleep apnea-hypopnea syndrome and tympanogram / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To explore the correlation between childhood obstructive sleep apnea-hypopnea syndrome and tympanogram.@*METHOD@#A prospective clinical study was carried out. Polysomnography and tympanogram were analyzed in 72 cases.@*RESULT@#Among the 144 ears 37 ears had type C or B tympanogram. There was no correlation between tympanogram and LSaO2. It was found correlation between tympanogram and AHI (P < 0.05).@*CONCLUSION@#Hypoxemia may affect middle-ear function. It was necessary to do the examination of acoustic impedance routinely in children with moderate and severe OSAHS.
