Investingation on Outcomes After Combining Septoplasty With Additional Procedures.

The aim of this study will be to compare postoperative nasal airflow and symptom improvement using a NOSE form in patients after different types of surgical treatment. Patients will be treated with one of the following operations: septoplasty with turbinectomy, septoplasty with radiofrequent ablation of the nasal turbinates, or septoplasty with valvuloplasty. This is a single-center prospective randomized interventional comparative study on patients in a tertiary rhinology center, who will undergo septoplasty alongside one additional rhinologic procedure aimed at improving nasal patency.

Impact of Palatal Expansion and Up-Locker Activator on Sleep and Pharyngeal Dimensions in Children

Objective: The study will aim to compare the effect of palatal expansion with Hyrax and Hyrax combined with Up-Locker on sleep behavior, sleep architecture, quality of life and nasal and pharyngeal airway dimensions, as well as intermolar, intercanine, and palatal depth dimensions in children. Materials and Methods: This prospective, single-blind, randomized controlled clinical trial will enroll 34 children aged 6-8 years, who will be randomly assigned to receive treatment with either the Hyrax expansion appliance alone or in combination with the Up-Locker vacuum activator. Intercanine, intermolar, and palatal depth dimensions will be evaluated through intraoral scans. Airway dimensions will be assessed using panoramic and lateral cephalometric radiographs, while sleep behavior will be analyzed with the Children's Sleep Habits Questionnaire (CSHQ) and sleep architecture will be evaluated via polysomnography. Data will be analyzed using the Shapiro-Wilks test for homogeneity, and comparisons will be performed with either the t-test or the Mann-Whitney U test. Results: It is expected that intercanine and intermolar distances will improve in both the Hyrax and Hyrax combined with Up-Locker vacuum activator groups after treatment, while palatal depth will present a significant reduction only in the group receiving Hyrax with Up-Locker. The group using the Hyrax combined with Up-Locker vacuum activator will likely experience more significant improvements in sleep latency, total sleep time, REM sleep, and arousal indices compared to the Hyrax group (p\<0.05) after treatment. Both groups are anticipated to demonstrate reduction of snoring, enhanced airway dimensions post-treatment, including the area of the nostrils and the naso and oropharynx. Conclusion: It is expected that combined treatment with Hyrax and Up-Locker vacuum activator will yield superior outcomes in sleep architecture, intraoral dimensions, and airway dimensions.
