OBJECTIVES: Chronic rhinosinusitis with and without nasal polyps (CRSwNP and CRSsNP) and antrochoanal polyps (ACP) are different upper airway inflammation phenotypes with different pathomechanisms. In order to understand the development of tissue edema, the present study aimed to evaluate lymphatic vessel density in CRSsNP, CRSwNP and ACP. MATERIALS AND METHODS: 120 retrospective nasal and maxillary sinus specimens were stained immunohistochemically with a von Willebrand factor polyclonal antibody recognizing vascular and lymphatic endothelium, and with a podoplanin monoclonal antibody recognizing lymphatic endothelium...

BACKGROUND: This study aimed to assess clinical outcomes of long-term low-dose oral doxycycline therapy in difficult-to-treat chronic rhinosinusitis with polyps (CRSwNP). METHODS: This was a prospective, open-label study of 60 patients with difficult-to-treat CRSwNP who had undergone endoscopic sinus surgery. Patients were divided into two groups: 28 received nasal steroids, saline irrigation, and doxycycline (200 mg on the first day, followed by 100 mg once daily) for 12 weeks, while 30 received only nasal steroids and saline irrigation...

Asian noses are mainly characterized by a low nasal dorsum, a short nose and an underprojected nasal tip due to underdeveloped (short and weak) alar cartilages. The goals of the surgery are to increase the tip projection, elongate the nose and augment the dorsum. In Asian noses the structural approach helps strengthen the weak cartilages and add definition to the nasal tip. There are various methods to increase tip projection and definition. Columellar strut, caudal septal extension graft, tip grafts and lateral crural grafts in order to elongate the upper legs of the nasal tip tripod can be used...

Upon inducting general anesthesia in the operating room, we have observed a prompt increase in the bispectral index (BIS) after the intravenous injection of suxamethonium. We hypothesized that the cause of this BIS increase is muscle hyperactivity owing to fasciculation. However, no reports have been published regarding this abrupt increase in the BIS upon the induction of general anesthesia by suxamethonium. To investigate the degree of change in the BIS in patients receiving anesthesia with suxamethonium, we performed a prospective observational study of 63 participants who underwent closed reduction for nasal bone fracture...

CASE DESCRIPTION A 4-hour-old 6.3-kg (13.9-lb) female alpaca cria was evaluated because of severe respiratory distress and difficulty nursing since birth. CLINICAL FINDINGS The cria had open-mouth breathing and cyanotic membranes, with no airflow evident from either nostril. Supplemental oxygen was delivered, and the patient was anesthetized and intubated orotracheally; a CT evaluation of the head confirmed bilateral membranous obstruction of the nasal cavities, consistent with complete bilateral choanal atresia...

INTRODUCTION: Spontaneous cerebrospinal fluid (CSF) fistulas are infrequent and only 10 cases in the literature have been located in the clivus. We describe two new cases of CSF fistulas in this site and review the literature. CASE REPORT: The first patient was a 52-year-old woman referred to our centre for intermittent rhinorrhea that had been diagnosed after an episode of meningitis. The second case was a 69-year-old man who was visited for rhinorrhea of one-year duration; he also developed meningitis during the preoperative study...

Purpose. To report the safety and efficacy of adjustable postoperative position for rhegmatogenous retinal detachment (RRD). Methods. Retrospective review of 536 consecutive RRD eyes that underwent vitrectomy surgery for retina repair from year 2008 to 2014. The retinal breaks were divided into superior, lateral (nasal, temporal, and macular), and inferior locations, according to the clock of breaks. Patients with superior and lateral break location were allowed to have facedown position or lateral decubitus position postoperatively, while patients with inferior break location were allowed to have facedown position...

In this study, we analyze and discuss the treatments of postoperative nasal complications after endonasal transsphenoidal resection of pituitary neoplasms (PNs). We performed 129 endonasal transsphenoidal resections of PNs and analyzed and treated cases with nasal complications. After endonasal transsphenoidal resection of PNs, there were 26 cases of postoperative nasal complications (20.1%), including nasal hemorrhage (4.8%), cerebrospinal fluid rhinorrhea (6.9%), sphenoid sinusitis (2.3%), atrophic rhinitis (1...

The nose forms the first 8 cm of the upper respiratory tract and is responsible for cleansing, humidification, and temperature control of the supplied air. This is also referred to as conditioning. The nasal valve region, formed by the head of the lower nasal concha, portions of the cartilaginous septum, and the upper lateral cartilage, is responsible for diffusing and accelerating the respiratory airflow. Prerequisite are regular mucociliary clearance and sufficient air passage. Hypertrophy of the lower nasal turbinate is one of the most common causes of symptomatic nasal congestion...

BACKGROUND: The surgical excision of anatomic obstructions such as adenoids, palatine or lingual tonsils are commonly performed in children with sleep disordered breathing (SDB). Imaging studies measuring airway changes post-surgery in the SDB pediatric population are scarce, rarely addresses the nasal cavity, and are based on global measures (e.g. volume) that do not represent the complexity of the upper airway anatomy. The purpose of this pilot is to test the feasibility in using cone beam CT (CBCT) to analyze the nasal and pharyngeal airway space post-surgery using meaningful methods of analyses, and correlating imaging findings with clinical outcomes in children with SDB symptoms and maxillary-mandibular disproportion...

BACKGROUND: The standard treatment for esthesioneuroblastoma, a rare malignant nasal vault neoplasm, is not established. METHODS: We retrospectively assessed the clinicopathological features, prognostic factors and treatment methods for 187 patients with esthesioneuroblastoma treated in China between 1981 and 2015. Overall survival (OS) and disease-free survival (DFS) were evaluated using the Kaplan-Meier method and log-rank tests. RESULTS: Twenty-three (12...

BACKGROUND: Several correlations between morphological and/or positional alterations of the jaws and respiratory functional impairments have been reported. NAO (Nasal airway obstruction) represents a big deal with no clearly defined "gold- standard" in measurement. Rhinomanometry was adopted by multiple Authors to evaluate whether patients with malocclusion developed respiratory functional changes after an orthodontic-surgical treatment. However there are contrasting findings in literature regarding the possibility of improving respiratory function by means of SARPE or bimaxillary repositioning of the bony bases...
