Clinical effect of surgical correction for nasal pathology on the treatment of obstructive sleep apnea syndrome.

Objectives: This study aimed to evaluate the hypothesis that relief of nasal obstruction in subjects with obstructive sleep apnea (OSA) would lead to reduce OSA severity and to discuss the available evidence on the clinical efficacy of nasal surgery as a treatment modality for OSA.

Study Design: Twenty-five subjects who had reduced patency of nasal cavity and narrowing of retroglossal or retropalatal airways were diagnosed with OSA and underwent nasal surgery, such as septoplasty or turbinoplasty to correct nasal pathologies. The effect of the surgery on nasal patency was quantified by measuring minimal cross-sectional area (MCA) using acoustic rhinometry.

Clinical usefulness of watch-PAT for assessing the surgical results of obstructive sleep apnea syndrome.

Objective: This study aimed to assess the accuracy and clinical efficacy of a wrist-worn device that is based on peripheral arterial tonometry (watch-PAT) to evaluate the surgical results of obstructive sleep apnea (OSA) syndrome subjects.

Study Design And Method: Thirty-five subjects who were diagnosed with OSA and underwent sleep surgeries such as septoplasty, tonsillectomy, or uvuloplasty to correct their airway collapse, participated in this study; the watch-PAT-derived respiratory disturbance index (RDI), apnea and hypopnea index (AHI), lowest oxygen saturation, and valid sleep time were measured after the sleep surgery.

Results: The present study showed that RDI (32.

Analyzing serum eosinophil cationic protein in the clinical assessment of chronic rhinosinusitis.

Background: Eosinophil cationic protein (ECP) is a major granule-derived protein with cytotoxic activity found in eosinophils and has been known as a useful marker of allergic inflammation. In this study, we assessed the clinical significance of ECP in chronic inflammation of the nasal mucosa by evaluating the relationship between eosinophil activity and serum ECP concentration in a cohort of subjects with or without chronic rhinosinusitis (CRS) and allergic rhinitis (AR).

Methods: We retrospectively reviewed the medical records of 492 subjects and analyzed eosinophil percentage in nasal smears, serum eosinophil counts, serum ECP concentrations, symptom scores, CT scores, the size of nasal polyp, and recurrence of CRS at follow-up.

Nighttime facial pain induced by myxoma of the maxillary sinus: a case report.

Myxomas of the maxillary sinus are uncommon benign tumors arising from the primitive mesenchyme. They may be related to dental malformations or missing teeth but may also occur without any abnormalities. They usually result in facial deformity manifested by slow, painless bony expansion.
