BACKGROUND: Nasal and paranasal cavities are supposed to contribute substantially to the vocal tract resonator properties. However, their acoustical effects as well as the effects of sinus surgery on the voice remain unclear. In this work we investigate resonance phenomena of paranasal sinuses prior to and after various rhinosurgical procedures in cadaveric human sinonasal tracts and corresponding 3D casts. METHODOLOGY: Nasal and paranasal cavities of formalin-preserved cadavers and corresponding 3D replicas were excited by sine-tone sweeps from an earphone placed in the epipharynx...

INTRODUCTION: Computed Tomography (CT) plays an important diagnostic role in patients with sinonasal diseases and determines the treatment. The CT images clearly show fine structural architecture of bony anatomy thereby determining various anatomical variation, extent of disease and characterization of various inflammatory, benign and malignant sinonasal diseases. AIM: To evaluate sensitivity and specificity of CT in diagnosis of sinonasal diseases and to characterise the benign and malignant lesions with the help of various CT parameters...

BACKGROUND: Despite the development of functional endoscopic endonasal surgery, there are still areas of the maxillary sinus that remain technically difficult to access using a standard middle meatal antrostomy as well as deep-seated skull base lesions requiring expanded transmaxillary approaches. METHODS: All patients who underwent transnasal endoscopic partial maxillectomy (TEPM) in a single institution from 2000 to 2014 were retrospectively reviewed. The TEPM was classified into 5 types according to the anatomic structures progressively removed and to the access provided...

PURPOSE OF REVIEW: The present article summarizes anesthetic techniques used during functional endoscopic sinus surgery to decrease bleeding and aid in creating a clear surgical field. The applicable physiology behind these anesthetic techniques is reviewed with emphasis on the effect on bleeding and the surgical field. Deliberate hypotension, reverse Trendelenburg positioning, regional anesthesia, and cerebral monitoring are discussed. RECENT FINDINGS: There are mixed data as to whether traditional inhalation anesthesia or total intravenous anesthesia is superior with respect to better surgical fields and decreased blood loss...

Balloon dilatation of sinus ostia (sinuplasty) was introduced in 2005 as a treatment for Chronic Rhinosinusitis (CRS).(1) It has been described as a 'transition space' tool for the ethmoidal infundibulum and frontal recess.(1) It can been used as a lone procedure or in combination with functional endoscopic sinus surgery (FESS) as a "hybrid" technique. Balloon sinuplasty applies the Seldinger technique to cannulate and dilate stenosed or occluded sinus ostia re-establishing drainage pathways and ventilation...

An otherwise healthy 34-year-old man was referred to our ear, nose and throat (ENT) clinic for a bilateral maxillary radiologic opacity. This condition was accidentally discovered with a panoramic radiography performed during a follow-up visit after a bilateral endodontic treatment. The patient did not report any specific sinonasal symptom such as purulent nasal discharge, loss of smell and cough, apart from an unspecific sinus pressure. The CT scans showed a bilateral inflammatory process into the maxillary-ethmoidal sinuses and an iron-like density within the maxillary sinuses, while nasal endoscopy showed purulent discharge in the ostiomeatal complex...

BACKGROUND: Bitter taste receptors (T2Rs), especially T2R38s appear as innovative regulators of innate immunity in the respiratory system. The single nucleotide polymorphisms (SNPs) in TAS2R38 gene may contribute to individual differences in susceptibility to respiratory infections especially chronic rhinosinusitis (CRS). TAS2R38 genotypes distribution varies by geographic region, race and ethnicity. The aim of the preliminary study was the identification of SNPs in TAS2R38 encoding genes in Polish patients with CRS and finding potential correlation with CRS phenotypes...

INTRODUCTION: Endoscopic sinus surgery is a minimally invasive procedure used to restore normal sinus ventilation and mucociliary function. It is a routine otolaryngology procedure with a success rate of about 90% for symptomatic improvement in patients with refractory chronic rhinosinusitis. Because of the proximity of the paranasal sinuses to the brain and the orbit, it cannot be performed without a potential risk of complications. In our case, without early clinical suspicion, proper diagnosis and management, this unusual occurrence of pneumomediastinum after endoscopic sinus surgery may have led to major complications or even death...

BACKGROUND: Sinonasal inverted papilloma is a locally aggressive tumor arising from the Schneiderian membrane which lines the nasal cavity and paranasal sinuses. Aggressive surgical approaches, such as lateral rhinotomy, were used until recently for complete removal of the inverted papilloma. Currently, endoscopic resection is the gold standard in the treatment of inverted papilloma. However, there are situations that justify an open approach. For example there are studies that report a higher postoperative recurrence rate after endonasal endoscopic resection, particularly in the treatment of recurrent diseases...

REVIEW
Corinna G Levine, Roy R Casiano
Refractory chronic rhinosinusitis can be challenging to treat. Initial treatment focuses on medical and nonsurgical treatments. If these treatments fail, revision endoscopic sinus surgery is an option. A plan for revision surgery must address anatomic factors contributing to recurrence. Preoperative imaging and sinonasal endoscopy are systematically reviewed; areas of disease and "danger" zones are identified. Traditional anatomic landmarks are often obscured or absent; thus, a set of consistent landmarks (unchanged despite prior surgery) are used to navigate the revision endoscopic sinus surgery...

BACKGROUND: Chronic rhinosinusitis (CRS) in European country ranges in elderly patients from 4.5 to 12% of population and has a significant effect on quality of life. In these patients, rhinosinusitis is linked to immune functions changes with age and to mucosal paraphysiological alterations such as crusting formations with atrophic epithelium, variations of nasal airflow and modifications of the mucociliary clearance. Failure of medical treatments leads to surgery in patients with persistent symptoms and radiographic signs of CRS...

BACKGROUND: Surgery improves symptoms for the majority of chronic rhinosinusitis (CRS) patients; however, physiological changes in the sinus cavities remain poorly characterized. Direct measurement of changes in airflow, pressure, temperature, humidity, and intranasal spray distribution following surgery is technically challenging. Accordingly, we have used computational fluid dynamic modeling to quantify how these parameters change postoperatively. METHODS: Computed tomography images from a normal control, a patient with CRS preoperatively and postoperatively, and a patient following an endoscopic Lothrop procedure (ELP) were used to create 4 three-dimensional models of the sinus cavities...

Background Endoscopic skull base approaches are being used to address complicated neurovascular pathology. These approaches are safest when proximal vascular control of the cavernous carotid artery (CavCA) can be obtained. Methods We present a cadaver-based anatomic simulation study showing the feasibility of clip placement for the CavCA as it courses through the cavernous sinus. The arterial vessels were injected with red microfil (Flow Tech, Carver, Massachusetts) to enhance visibility. The endoscope was directed through a precaruncular transorbital approach and instrumentation was managed through an endonasal transsphenoidal approach...
