RESUMEN
Multiple Sclerosis [MS] is a demyelinating disorder of Central Nervous System. It involves 8th cranial nerve and its central nuclei and is an uncommon cause of the sensorineural hearing loss. For determining the prevalence of hearing loss [HL] especially retrocochlear type in MS, a cross-sectional study was designed using Pure-Tone Audiometry [PTA], Otoacustic Emissions [OAEs], Auditory Brainstem Responses [ABRs] compared with the control group. Data were analyzed by Qui2 and Fischer exact test in SPSS 17 software. Among 60 patients [44 women and 16 men] and 38 controls [27 women and 11 men] with a mean age of 29.9 +/- 9.8 and 31.4 +/- 8.3 years, 12.5% of case ears and 3.9% of the control ears had abnormal PTA [P= 0.043]. Frequency of abnormal high frequency-PTA and two modalities of OAEs were not significantly different between case and control ears. The means of overall correlation were 75.9 +/- 23.8 in cases and 70.0 +/- 27.2 in controls [P= 0.111]. 20% of case ears, and 9.2% of the control ears had abnormal ABRs [P= 0.044]. The absolute latencies of waves I, II and V had not significant difference, but 10% and 11.7% of case ears and 1.3% and none of the control ears had increased inter peak latencies of I-III, and III-V respectively [P<0.05]. 6.7% of case ears and 2.6% of control ears had retrocochlear abnormality [P=0.181]. In conclusion, HL is more common in MS patients, especially when determined by using PTA and ABR
RESUMEN
Tonsil reduction by use of radiofrequency waves is one of the newest therapeutic modalities, especially for obstructive large tonsils. The aim of this study was comparing short term and long term results of radiofrequency tonsillotomy and traditional cold dissection tonsillectomy in adult patients with recurrent tonsillitis. a prospective randomized clinical trial on 72 adults with recurrent tonsillitis was performed in a tertiary referral university hospital. Traditional tonsillectomy in 34 cases and radiofrequency tonsillectomy [RF] by use of Radiofrequency Induced Thermotherapy [RFITT] probes in 38 cases were performed under general anesthesia. Time of surgery, amount of intraoperative bleeding, recovery time, post-surgical pain, dysphagia, weight loss, and time of return to normal diet and activity were measured. All the patients were followed for 24 months for recurrence of tonsillitis episodes. Statistical analysis was performed using SPSS version 16, chi square and Mann-Whitney U tests. Mean time of surgery [16.89 vs. 46.07 minutes] and recovery [14.32 min vs. 17.11 min], and amount of intraoperative bleeding [15-20 cc vs. 250-300cc] were significantly less in the RF group than the traditional tonsillectomy group [p<0.005]. There was no difference between the two groups in the recurrence of tonsillitis episodes after 24 months. Tonsillotomy with RF is a simple, rapid, and effective method in adult patients with recurrent tonsillitis
