Balloon Eustachian Tuboplasty

Objectives: Balloon eustachian tuboplasty (BET) is a promising therapeutic option for eustachian tube (ET) dysfunction. However, data are lacking on the effect of BET in adults with symptoms of chronic ET dysfunction but without a contributing pathology. This study investigated the effect of BET in adult patients with only symptoms of chronic ET dysfunction. Methods: This prospective clinical trial included adult patients with aerated physiological middle ears and symptoms of ET dysfunction for more than 6 months. Compliance with follow-up was 93.3%. We evaluated the effects of BET with tympanometry, assessment of the Valsalva or Toynbee maneuver with tympanometry verification, a Eustachian Tube Dysfunction Questionnaire (ETDQ-7), and pure-tone audiometry. Data were recorded 1 day before surgery and 2, 6, and 12 months after BET. Therapy was considered successful when the patient exhibited a newly acquired ability to perform the Valsalva or Toynbee maneuver or when the ETDQ-7 score improved by 20% or more. Results: We included 14 ears in the analysis. After 2, 6, and 12 months, therapy was successful, according to the ETDQ-7, in 11/14 (78.6%; 95% CI: 48.8-94.3), 13/14 (92.9%; 95% CI: 64.2-99.6), and 12/14 (85.7%; 95% CI: 56.2-97.5) ears, respectively. These results were statistically significant. The ETDQ-7 scores also significantly decreased at 2, 6, and 12 months after the BET, when any change was observed. All patients experienced improvement. Only 1 patient reported temporary deterioration after 2 months. Treatment was more frequently successful in patients without nasal polyps or pollinosis. Conclusions: Adults with only symptoms of chronic ET dysfunction benefitted more and had longer lasting results from BET, compared to patients with pathologies caused by ET dysfunction. Balloon eustachian tuboplasty could be recommended for these patients.

ABSTRACT Introduction This comparative prospective randomized clinical trial examined the in vivo failure rates of fixed mandibular and maxillary lingual retainers bonded with two light-cured flowable composites over 6 months. Materials and methods Consecutive patients were divided into two groups on a 1:1 basis. Two hundred fixed lingual retainers were included, and their failures were followed for 6 months. One group (n = 50) received retainers bonded with a nano-hybrid composite based on nano-optimized technology (Tetric-N-Flow, Ivoclar Vivadent). Another group (n = 50) received retainers bonded with a low viscosity (LV) composite (Transbond Supreme LV, 3M Unitek). Results There was no significant difference between the overall failure rates of mandibular retainers bonded with Transbond (8%) and those bonded with Tetric-N-Flow (18%). However, the odds ratio for failure using Tetric-N-flow was 2.52-fold greater than that of Transbond. The failure rate of maxillary retainers bonded with Transbond was higher (14%), but not significantly different, than that of maxillary retainers bonded with Tetric- N-flow (10%). There was no significant difference in the estimated mean survival times of the maxillary and mandibular retainers bonded with the two composites. Conclusion Both types of composites tested in the current study can be used to bond fixed maxillary and mandibular lingual retainers, with low failure rates. How to cite this article Talic NF.

This was a prospective controlled clinical trial. 48 myopia patients (96 eyes) were included in this study. After LASIK, accelerated corneal collagen cross-linking (ACXL) was used for myopia treatment. During 6-month follow-up, the results of LASIK-ACXL treatment were studied and compared to the LASIK-only procedure. The results showed that no statistically significant differences in UDVA, CDVA, MRSE,Kmean, pachymetry, or ECD were found between the two groups at the visit after 6 months of follow-up (allP>0.05). At 6 months postoperatively, 2 eyes lost one or more lines of visual acuity in the LASIK-ACXL group, whereas all LASIK-only treated eyes had a stable CDVA.In vivoconfocal microscopy showed a decrease of keratocyte density and appearance of honeycomb-like structures in the anterior residual stroma bed; the changes were similar but more pronounced following LASIK-only. None of the cases in both groups developed signs of significant keratitis, regression, or ectasia during the 6-month follow-up. LASIK-ACXL can effectively correct refractive error in patients with myopia, with no significant complications during 6-month follow-up, indicating stability and morphologic change similar to those with LASIK-only treatment.
