Background.We aim to provide useful evidence about the association of neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) with idiopathic sudden sensorineural hearing loss (ISSNHL) and its possibility of emerging as a cheap, reliable, and independent prognostic marker of ISSNHL.Methods.348 patients diagnosed with ISSNHL were included in our retrospective data analysis. Blood samples and the hearing assessments of the patients were carried out. Then, the patients were divided into 2 groups as “recovered” and “unrecovered” according to their response to the treatment.Results.Both mean NLR and PLR values of the ISSNHL patients were significantly higher than the control group (bothP<0.001). The NLR value was5.98±4.22in the unrecovered group and3.50±3.38in the recovered group (P<0.001). After adjustment in a binary logistic regression model, only NLR value was associated with the recovery of ISSNHL (P=0.001).Discussion.We demonstrated for the first time that NLR and PLR values were significantly high in ISSNHL patients. Also the NLR level might be taken into account as a novel potential marker to predict the patients’ prognosis in terms of recovery.

Objectives This study aimed to investigate the therapeutic efficacy of intratympanic dexamethasone (ITD) as a salvage treatment in sudden hearing loss (SHL) patients who had no response to initial systemic combination steroid therapy. Patients and Methods From May 2007 to June 2010, 415 SHL patients visited 3 tertiary referral centers within 7 days of disease onset. They were all treated with an identical protocol, a 10-day scheduled hospitalization and oral steroid treatment. Of these, 151 patients were totally unresponsive 2 weeks after treatment initiation according to Siegel’s criteria. We divided these 151 refractory patients into 3 groups: those receiving no further treatment (control group, n = 59), those receiving one more 10-day cycle of oral steroids (systemic reapplication group, n = 26), and those receiving ITD therapy (ITD group, n = 66). Final assessment of hearing was conducted approximately 3 months after the onset of SHL. Hearing improvement was defined as demonstrating “any” improvement according to Siegel’s criteria. Results The initial average hearing thresholds of all groups were similar. Overall hearing improvement was observed in 10 of 59 patients in the control group, in 4 of 26 in the systemic reapplication group, and in 32 of 66 in the ITD group. No serious complications were observed. Analyzing by frequency, paradoxically, hearing of the low and mid frequencies was more significantly improved than high frequencies in the ITD group. Conclusion Intratympanic dexamethasone administration after failure of an initial treatment is effective, and this should be used as a salvage treatment in cases of refractory SHL.

Objective For tympanoplasty, the most common grafting materials are the temporalis fascia or perichondrium; however, both require incision of the canal skin, which carries a risk of morbidity and the need for postoperative care. Inlay butterfly cartilage tympanoplasty, by which the perforation edges are refreshed and a cartilage is inserted through the perforation without canal incision, makes the graft easy, and reduces operating and recovery time. We analyze the outcome of inlay butterfly cartilage tympanoplasty. Materials and Methods This study included 112 patients who underwent tympanoplasty from January 2011 to August 2012. Patients were divided into 2 groups: patients who underwent inlay butterfly cartilage tympanoplasty (Group I, n = 56) and patients who underwent conventional underlay tympanoplasty using the temporalis fascia (Group II, n = 56). Anatomic success was defined as an intact, repaired tympanic membrane, and functional success was defined as a significant decrease in the air-bone gap at the end of follow-up. Perioperative pain was analyzed using a visual analogue scale (VAS). Surgical success, functional success, perioperative pain, and operating time were evaluated and compared. Results The surgical success rate was 96.4% in Group I and 91.1% in Group II (p = 0.435). The mean air-bone gap decrease was 7.9 ± 2.2 dB in Group I and 8.9 ± 3.2 dB in Group II (p = 0.426). Group I showed a lower VAS score for pain (1.5 ± 1.2) and a shorter operation time (25.6 ± 8.5 min) compared with those of Group II (4.9 ± 1.7, 48.6 ± 19.5 min, respectively) (p < 0.01). Conclusion Inlay butterfly cartilage tympanoplasty is compatible with the conventional underlay technique in both anatomic and functional success rates. Its simplicity, shorter operation time, and rapid recovery time could make it an attractive surgical option.

Benign paroxysmal positional vertigo (BPPV) can be treated using a simple repositioning maneuver. This study demonstrates the effects of early repositioning therapy in patients with BPPV, especially with regard to recurrence. We enrolled 138 consecutive patients who had been diagnosed with BPPV in the emergency rooms and ENT out-patient clinics of Chung-Ang University Hospital and Samyook Medical Center from January to June 2009. All patients immediately underwent appropriate canalith repositioning procedures (CRPs) depending on canalith type and location. The CRPs were performed daily until the patient's symptoms were resolved. The patients were classified into two groups according to the duration between symptom onset and initial treatment: less than 24 hours (early repositioning group, n=66) and greater 24 hours (delayed repositioning group, n=72). We prospectively compared the numbers of treatments received and the recurrence rates between the two groups. Follow-up periods ranged from 8 to 14 months, 77 cases involved posterior canal BPPV, 48 cases were lateral canal BPPV (of which 20 cases were cupulolithiasis), and 13 cases were multiple canal BPPV. BPPV recurrence was found in a total of 46 patients (33.3%). The necessary numbers of CRPs were 2.3 for the early repositioning group and 2.5 for the late repositioning group, a difference that was not statistically significant (P=0.582). The early repositioning group showed a recurrence rate of 19.7%, and the delayed repositioning group showed a recurrence rate of 45.8% (P=0.002). Performing repositioning treatments as soon as possible after symptom onset may be an important factor in the prevention of BPVV recurrence.
