OBJECTIVES This study aims to determine the anatomical changes occurring in the nasal septal body (NSB) among patients with sinonasal disease and compares the measurements obtained from patients without sinonasal disease. METHODS This was a retrospective study involving review of 405 (93 without and 212 with sinonasal disease) plain paranasal sinus computed tomography (PNS CT) on coronal view...

INTRODUCTION The only anatomical variation of the superior turbinate defined in the literature is concha bullosa. Determination of anatomical variations of the intranasal structures is important to perform safe endoscopic sinus surgery and avoid complications. CASE PRESENTATION We report a case of an unusual anatomical variation of the superior turbinate in a 55-year-old Turkish man with nasa...

It has been postulated that the nasal mucosa, like other human tissues, is affected by a complex interactive network of neuropeptides, cytokines, allergic and inflammatory mediators and hormones such as estrogen, in which associations between symptoms (e.g. nasal stuffiness and coryza) and hormonal variations deriving from pregnancy, use of hormonal contraceptives and menstrual cycle phases are...

BACKGROUND Staphylococcus aureus (S. aureus) plays an important role in the pathogenesis of severe chronic airway disease, such as nasal polyps. However the mechanisms underlying the initiation of damage and/or invasion of the nasal mucosa by S. aureus are not clearly understood. The aim of this study was to investigate the interaction between S. aureus and herpes simplex virus type 1 (HSV1) in...

Background: The inferior turbinate, as part of the nasal valve area, plays a key role in directing the airflow and moisturizing and heating the inspired air. Excessive resection of the inferior turbinate leads to a significant reduction in heating and humidification of inhaled air. Different types of turbinate surgery are described in the current literature. Pyriform Turbinoplasty is a new endo...

OBJECTIVE To investigate the aerodynamic consequences of conservative unilateral inferior turbinate reduction using computational fluid dynamics methods to accomplish detailed nasal airflow simulations. DESIGN A high-resolution, finite-element mesh of the nasal airway was constructed from magnetic resonance imaging data of a healthy man. Steady-state, inspiratory airflow simulations were cond...

Two auxiliary methods of diagnosing nasopharyngeal airway obstruction were compared. Cephalometric radiography and nasopharyngeal videoendoscopy were evaluated for efficacy in terms of reproducibility and validity. Thirty orthodontic patients (7 to 12 years of age) seeking otorhinolaryngologic treatment for mouth breathing, or mouth and nose breathing, had nasopharyngeal endoscopy and radiograp...

OBJECTIVE To determine the effect of improved nasopharyngeal airflow after adenoidectomy on nasal turbinate erectile tissue in pediatric patients. DESIGN Clinical, prospective, before-and-after study. SETTING Pediatric Otolaryngology Clinic at Hospital da Criança Santo Antônio de Porto Alegre (Complexo Hospitalar Santa Casa de Porto Alegre). PATIENTS Twenty-one 5- to 11-year-old children ...

Introduction: Nasal inferior turbinate hypertrophy is one of the most common causes of nasal obstruction. Many different surgical methods are currently available. The aim of this study was to review the efficacy and results of radiofrequency turbinatoplasty as a new method in the treatment of the large inferior nasal turbinate. Materials and Methods: This prospective study was conducted on 5...
