Computational Fluid Dynamics Could Enable Individualized Surgical Treatment of Nasal Obstruction (A Preliminary Study).

Passage of nasal airflow during breathing is crucial in achieving accurate diagnosis and optimal therapy for patients with nasal disorders. Computational fluid dynamics (CFD) is the dominant method for simulating and studying airflow. The present study aimed to create a CFD nasal airflow model to determine the major routes of airflow through the nasal cavity and thus help with individualization of surgical treatment of nasal disorders.

Evolution of mucosal vasculature after radiotherapy of T1 vocal cord cancer: a pilot study.

Purpose: Narrow-band imaging is the state of the art in the diagnosis of mucosal lesions of the vocal cords. It is also used in the follow-up of patients after surgical therapy. Unfortunately, if a patient has received radiotherapy the follow-up is much more difficult.

Epiglottopexy Is a Treatment of Choice for Obstructive Sleep Apnea Caused by a Collapsing Epiglottis.

Drug-induced sleep endoscopy (DISE) reveals epiglottic collapse to be a frequent cause of obstructive sleep apnea (OSA) and intolerance of positive airway pressure (PAP). These patients require different management. This prospective study aimed to compare transoral laser epiglottopexy outcomes in patients with OSA caused by epiglottic collapse with the patients’ previous PAP outcomes.

Does Bicanalicular Intubation Improve the Outcome of Endoscopic Dacryocystorhinostomy?

Unlabelled: The aim of this study was to compare the success of endoscopic dacryocystorinostomy with and without bicanalicular intubation in the treatment of distal nasolacrimal duct obstruction.

Methods: In a prospective, randomized, comparative study, endoscopic dacryocystorinostomy without bicanalicular silicone intubation (Group I) and endoscopic dacryocystorinostomy with intubation (Group II) were performed in patients with distal nasolacrimal duct obstructions. The tubes were removed 3 months after surgery in Group II, and the patients were followed up for 6 months after surgery.

Endoscopic Transcaruncular Medial Orbitotomy as an Alternative Approach to Anterior Ethmoidal Artery Coagulation.

Background: The authors present a series of 5 patients with anterior epistaxis in which a transcaruncular endoscopic approach was used for the anterior ethmoidal artery coagulation (AEA).

Methods: Six AEA coagulations (5 unilateral, 1 bilateral) using the transcaruncular endoscopic approach were performed in 5 patients with anterior epistaxis resistant to conservative measures. An incision was made between the plica semilunaris of conjunctiva and the lacrimal caruncle.

Dexamethasone Reduces the Incidence of Postoperative Nausea and Vomiting in Children Undergoing Endoscopic Adenoidectomy under General Anesthesia Without Increasing the Risk of Postoperative Hemorrhage.

BACKGROUND Postoperative nausea and vomiting (PONV) is a common complication of pediatric anesthesia, but the overall incidence of PONV in patients undergoing adenoidectomy is unknown. The aim of this controlled study was to compare the effect of dexamethasone administration with placebo to reduce PONV in children undergoing endoscopic adenoidectomy under general anesthesia. MATERIAL AND METHODS A randomized placebo-controlled study included 118 pediatric patients who underwent elective endoscopic adenoidectomy under general anesthesia.
