RESUMEN
OBJECTIVES: Obesity rates have been increasing for all population groups worldwide, leading to the increased development of various diseases. This study was designed is to identify the relationships between obesity and several important otorhinolaryngologic diseases, including chronic otitis media (COM), chronic rhinosinusitis, and chronic tonsillitis. METHODS: Mean body mass index (BMI) was compared in patients with COM, rhinosinusitis, and tonsillitis and in a control group. The relationships among the prevalence rates of overweight and obesity, morbidity period, and BMI were assessed in each group. RESULTS: Mean BMIs in the COM, rhinosinusitis, and tonsillitis groups were 24.45+/-2.72 kg/m2, 24.68+/-3.25 kg/m2, and 24.67+/-3.82 kg/m2, respectively, with each significantly higher than in the control group (23.22+/-3.01 kg/m2, P0.05 each). CONCLUSION: Mean BMI and the prevalence of obesity were elevated in the three groups of patients with representative otorhinolaryngologic inflammatory diseases, including COM, chronic rhinosinusitis, and chronic tonsillitis.

BACKGROUND AND OBJECTIVES: Increases in older aged populations and exposure to complicated noise environments have increased the number of hearing-impaired patients, creating greater demands for hearing aids. We have assessed the reasons that individuals rejected wearing and returned properly prescribed hearing aids, as well as differences in individual factors between younger and elderly adults. SUBJECTS AND METHODS: Of 1138 patients for whom hearing aids were prescribed at Kyung Hee University Medical Center Hearing Aid Clinic, 81 (6.14%) returned their hearing aids, including 36 patients aged or =65 years. Patient-related, hearing-related, and hearing aid-related factors were assessed by retrospective chart analysis and phone survey and compared in the two groups. RESULTS: The primary symptoms reported by the 81 patients who returned their hearing aids were hearing disturbance, ringing, and fullness in the ear, in that order and in both groups. The rate of hearing aid return was similar in elderly females and males (p=0.288). The spondee recognition threshold was significantly higher in younger than in elderly adults (63.3+/-14.0 dB vs. 55.6+/-14.74 dB, p=0.019), but the hearing aid return rate was highest in patients with moderate hearing loss in both groups. In evaluating the reasons for return of hearing aids, we found that ineffectiveness of the device was the most frequent reason, accounting for 32.0% of returns, the highest percentage in both groups, with the most frequent patient problem caused by management difficulty in elderly and financial difficulty in younger adults. CONCLUSIONS: The reasons for hearing aid return were different in two groups. Financial considerations were cited more by younger adults, while difficulties in managing hearing aids were cited more frequently by elderly adults. Patients in both groups, however, reported that the most frequent reasons for return were inadequate hearing improvement and inconvenience wearing the hearing aid due to noise amplification.

OBJECTIVES: Although many studies have assessed sudden deafness in adults, sudden deafness has not been evaluated in children. We therefore evaluated the differences in sudden deafness between children and adults. METHODS: We compared clinical manifestations, including gender, audiogram pattern of initial hearing loss, and recovery rate after treatment in 87 children and 707 adults diagnosed with sudden deafness from September 2003 and August 2012. RESULTS: There were no differences in sex, side, or audiogram between children and adults (P>0.05 each). Hearing recovery rates in children and adults were 72.4% and 70.6%, respectively (P>0.05). Both children and adults with mild hearing loss showed significantly greater hearing recovery rates than individuals with profound hearing loss (P<0.05 each). The percentage with initially mild and moderate hearing loss was higher in children than in adults, as were the recovery rates of children compared to adults with initially mild, moderate-severe, and profound hearing loss (P<0.05 each). In regard to final hearing outcome after treatment, a low percentage of children showed no improvement whereas a high percentage showed complete recovery; a higher percentage of children than of adults showed complete recovery (P<0.05). Recovery rate from profound hearing loss was significantly higher in children than in adults (60.0% vs. 45.4%, P<0.05). CONCLUSION: Degree of hearing loss, gender, side, and recovery rate were similar in children and adults, but the rate of complete recovery was higher in children.

PURPOSE: Even though aural fullness is ubiquitous among patients presenting to otolaryngology clinics, the association between aural fullness and disease development has not yet been clearly determined. MATERIALS AND METHODS: Our study was performed on outpatients from June 2006 to February 2010 whose major complaint was "ear fullness", "aural fullness", or "ear pressure". We assessed their demographic and clinical characteristics, including sex, associated diseases, symptoms, otoscopic findings, audiology test results, and final diagnoses. RESULTS: Among 432 patients, 165 (38.2%) were males and 267 (61.8%) were females, with mean ages of 42+/-19 years and 47+/-17 years, respectively. Tinnitus, hearing disturbance, autophony (p<0.01) as well as nasal obstruction and sore throat (p<0.05) showed a statistically significant correlation with aural fullness. Among patients who complained of hearing fullness, tests and measures such as impedance audiometry, speech reception threshold, and pure tone audiometry generated statistically significant results (p<0.05). Ear fullness was most frequently diagnosed as Eustachian tube dysfunction (28.9%), followed by otitis media with effusion (13.4%) and chronic otitis media (7.2%). However, 13.4% of patients could not be definitively diagnosed. CONCLUSION: Among patients complaining of ear fullness, Eustachian tube dysfunction, otitis media with effusion, chronic otitis media were most commonly observed. Performance of otoscopy, nasal endoscopy, the Valsalva maneuver, and additional audiological tests is necessary to exclude other diseases.

BACKGROUND AND OBJECTIVES: The repetitive Transcranial Magnetic Stimulation (rTMS) is generally performed over the course of several weeks, as its theoretical and experimental validity has been identified in repetitive procedures. If short term application of rTMS is proven to be significantly effective, more effective treatment of tinnitus can be expected. This study was conducted to measure the effect of one session of sham rTMS & one real trial of rTMS in chronic unilateral tinnitus patients. SUBJECTS AND METHOD: rTMS stimulation of 1 Hz and 100% magnitude was given 1200 times per day to 33 patients with chronic unilateral tinnitus on their left side, between T3 and C3/T5, following the convention of the 10-20 International EEG system. Visual Analogue Scale (VAS) and Tinnitus Handicap Inventory (THI) scores were measured four times-immediately before rTMS, immediately after sham rTMS, immediately after real rTMS and two weeks after real rTMS. RESULTS: VAS and THI scores were found to show a tendency of declining. Immediately after real rTMS application, a significant decrease in VAS and THI scores was observed compared to those measured immediately before rTMS (p0.05) attributable to the direction of tinnitus were observed. CONCLUSION: A single session rTMS is thought to be a possible adjunctive treatment for tem-porary relief of tinnitus.

The aim of this study was to compare the root canal systems of maxillary and mandibular premolars that had a single root using radiographs and clearing samples. 142 single rooted premolars were selected and mesio-distal and bucco-lingual views were radiographed using intra-oral dental standard films. Four equally trained examiners classify the root canal types from the developed radiographs. After opening the tooth for access, it was stored in 5% NaOCl to dissolve the pulp tissue. Indian ink was then injected into the pulp cavity to stain the pulp tissue. It was cleared in methyl salicylate after being decalcified with 5% nitric acid for 48 hours, and the root canal type was evaluated at a magnification of x 20 using a stereomicroscope. The results are as follows; There were statistically significant differences between the radiographs and clearing samples of the root canal types among examiners (p < 0.05). There might be differences in the root canal types among examiners when the same radiograph is used. Therefore, considering the difficulty in estimating the root canal types, clinicians need to be careful when interpreting radiographs before root canal therapy.
