We evaluated the effects of adenoidectomy and adenotonsillectomy (AT) on tympanostomy tube (TT) reinsertion using population-based retrospective cohort data to confirm the association of adenoidectomy or AT with TT reinsertion reported in several previous studies.

This study used data from the National Health Insurance Service National Sample Cohort in Korea. We selected patients who underwent TT insertion between the ages of 0 and 9 years from 2006 to 2015. Patients were divided into the following groups group 1, TT insertion only; group 2, TT insertion with adenoidectomy; and group 3, TT insertion with AT. The number of TT reinsertions was analyzed.

There were 745 patients in group 1, 115 in group 2, and 251 in group 3. There were 1,019 cases of total TT insertion and 336 of reinsertion in group 1, 169 of total TT insertion and 31 of reinsertion in group 2, and 343 of total TT insertion and 50 of reinsertion in group 3. The rates of TT reinsertion were significantly lower in groups 2 and 3 than in group 1. The risks of TT reinsertion in groups 2 and 3 were significantly lower than the risk in group 1 in both univariate and multivariate Cox regression analysis.

TT reinsertion was significantly lower in the TT insertion with adenoidectomy and TT insertion with AT groups than in the TT insertion only group. We confirmed the effects of adenoidectomy and AT on reduction of the rate of repeated TT insertion by analysis of population-based data.

This study aimed at evaluating the clinical significance of hematological findings in patients with acute peripheral facial palsy.

For this retrospective case series review, 84 patients who visited our university hospital and were diagnosed with Bell's palsy (BP) or Ramsay Hunt syndrome (RHS) between March 2017 and March 2019 were enrolled. We documented their epidemiological details, final diagnoses, House-Brackmann (HB) palsy grades, and pretreatment and day 7 post-hospitalization complete blood counts. The outcome was considered favorable if the HB grade at weeks 10-16 was I or II. We analyzed the hematological findings in terms of diagnosis and the final treatment outcomes.

A higher pretreatment neutrophil-to-lymphocyte ratio (NLR) and neutrophil count and a lower day-7 lymphocyte count were observed in patients with RHS with unfavorable outcomes. In such patients, moderate positive correlations were observed between the pretreatment white blood cell, neutrophil, and basophil counts; the NLR and basophil-to-lymphocyte ratio; and the initial HB grade. Only the latter was a significant risk factor for a poor treatment outcome. In patients with BP, both the initial HB grade and the pretreatment eosinophil count were included in a regression model predicting prognosis.

Inflammation plays an important role in RHS pathogenesis. Initial RHS severity and the response to corticosteroids may determine the final treatment outcome. However, inflammatory markers do not predict all BP outcomes; BP may be etiologically heterogeneous.

This study aims at comparing the tone-burst (TB) and narrow-band (NB) CE-chirp stimuli in terms of amplitude, latency, and interaural asymmetry ratio (IAR) in ocular vestibular evoked myogenic potentials (oVEMP).

In this prospective study, we enrolled 60 healthy subjects (27 men, 33 women) with a mean age of 25.83 (range, 18-48) years. Otological examination was normal in all the subjects. The subjects did not have any otological disease. All the subjects underwent oVEMP testing. this website We used 500 Hz TB stimulus and 500 Hz NB CE-chirp stimulus in random order. oVEMP test was performed at 100 dB normalized hearing level. P1 latency, N1 latency, and P1N1 amplitude were measured for each ear and stimulus, and IAR was calculated.

Ocular VEMPs were obtained from all the subjects for both the stimuli. P1 and N1 latencies were significantly shorter in chirp stimulus than in TB stimulus for both the sides (p<0.0001). P1 and N1 amplitudes were significantly higher for chirp stimulus than for TB stimulus for both the sides (p<0.0001). There was no significant difference between the ears in IAR between the 2 types of stimuli.

Narrow-band CE-chirp stimulus is an effective stimulus to evoke oVEMP with higher amplitudes and shortened latencies.

This study aimed to compare the Eustachian tube (ET) and the paratubal structures between the two sides in subjects with unilateral acquired cholesteatoma and a healthy contralateral ear to determine if there are anatomical differences.

Of the 217 patients with cholesteatoma evaluated, 36 patients with unilateral cholesteatoma were included in the study. All of the patients had a healthy contralateral ear with no history of surgery. Nine different paratubal parameters were measured through contrast-enhanced magnetic resonance imaging (MRI). The measurements of the ear with cholesteatoma were compared with those of the healthy ear.

The bimucosal thickness of the ET lumen, the mucosal thickness of the pharyngeal orifice, the lengths and diameters of the tensor veli palatini muscle and the levator veli palatini muscle, the diameter of the pharyngeal orifice of the ET, the diameter of the lateral pharyngeal recess mucosal thickness, and the diameter between the posterior border of the inferior nasal concha and the pharyngeal orifice of the ET were measured in MRI scans. No statistically significant difference was observed between the healthy ear and the ear with cholesteatoma for any of the parameters measured (p>0.05).

We did not observe any anatomical differences in the measurements of the ET and the paratubal structures on MRI scans. Although ET dysfunction is considered to be the leading etiologic factor in acquired cholesteatoma, the ET and the paratubal structures may not exhibit an anatomic difference between the ear with cholesteatoma and the healthy contralateral ear.
