To date, most frontal mucoceles are treated endoscopically, provided that there is no major neo-osteogenesis and that the frontal sinus floor is wide enough to provide an adequate working space: the presence of a sinus wall dehiscence is not considered as a contraindication to an endoscopic approach. We report on a series of 37 patients presenting with frontal sinus mucoceles with posterior table erosion. Thirty-three (89.2%) had minimal erosion and/or a limited protrusion of the mucocele within the anterior cranial fossa on CT-scan, and were successfully operated on through an endoscopic approach...

Functional endoscopic sinus surgery (FESS) has considerably evolved over the past 20 years while minimally-invasive surgery also applies to sinus procedures. Development of new technologies combined with better knowledge of risks has allowed surgeons to achieve improved results in their FESS indications. One of the most difficult areas to visualize using the exclusive endoscopic approach is still the anterior recess of the maxillary sinus. Hence, external approaches, such as the Caldwell-Luc procedure, are still used by many surgeons to ensure visual control of this area in diseases such as fungal balls, mucoceles, inverted papilloma and other tumors...

The objective of the present work was to study topographical and anatomical relationships between the lacrimal passages and the walls of the nasal cavity from the standpoint of the rhinosurgeon. The materials for the study were obtained by examining 15 corpses. It was found out that in 91% of the cases, the natural ostium of the maxillary sinus is localized within 11.6 cm from the lacrimal tubercle. In 62% of the cases, the nasolacrimal passage opens in the region of the vault of the inferior nasal passage as an orifice roughly 0...

Frontal sinus mucoceles are benign, pseudocystic lesion deriving from the obliteration of the sinus ostium, resulting in a continuous mucous accumulation. The growing process of a mucocele leads to a progressive enlargement of the sinus cavity, thickening and eroding its bony walls up to invading the surrounding tissues. The surgical procedure through an endoscopic endonasal approach is the current treatment option for such conditions, but in cases with an extensive bone erosion and intracranial or intraorbital extension, a transcranial approach should be preferred...

BACKGROUND: Chronic rhinosinusitis with and without nasal polyps (CRSw/sNP) are common conditions decreasing health-related quality of life (HRQOL). Individual symptoms capable of predicting outcome after endoscopic sinus surgery (ESS) are poorly defined, and the indirect costs of CRS is rarely reported in Europe. METHODOLOGY: Patients with CRSw/sNP admitted for ESS were prospectively enrolled. Patients completed the 22 Sinonasal Outcome Test (SNOT-22), the short-form 36-item questionnaire (SF-36), a Visual Analogue Scale (VAS) and reported CRS-related absenteeism pre- and post-operatively...

INTRODUCTION: In esthesioneuroblastoma, greater disease extent and Kadish staging correlate with greater recurrence, complications, and mortality. These advanced stage malignancies require extensive resections and aggressive adjuvant therapy. This increases the risk of complications such as cerebrospinal fluid leak, neurologic deficits, and osteomyelitis. We present our case series and then analyze the literature to ascertain whether advanced stage tumors corresponds to greater rates of complications...

BACKGROUND: Fungal sinusitis is increasing worldwide in the past two decades. It is divided into two types including invasive and noninvasive. Noninvasive types contain allergic fungal sinusitis (AFS) and fungus ball. AFS is a hypersensitivity reaction to fungal allergens in the mucosa of the sinonasal tract in atopic individuals. The fungus ball is a different type of noninvasive fungal rhinosinusitis which is delineated as an accumulation of debris and fungal elements inside a paranasal sinus...

Surgical morbidity from open reduction and internal fixation (ORIF) of maxillary sinus wall fracture often surpasses the benefits of ORIF. Hence, the authors devised transnasal endoscopic-assisted reduction of maxillary sinus wall fracture (TERM) without internal fixation as a minimally invasive surgery for maxillary sinus wall fracture. The purpose of this study was to investigate the feasibility of TERM in cadavers and patients. Six cadavers were dissected to evaluate the feasibility of TERM. In addition, 20 patients with maxillary sinus wall fractures who underwent TERM in a tertiary hospital from August of 2013 to December of 2015 were enrolled in this study...

Vascular headache and chronic rhinosinusitis (CRS) are diseases that share similar symptoms and demographics, including headache, facial pain and nasal symptoms. Contribution of chronic sinusitis as a cause of chronic headache is controversial, as there are scarce studies to know incidence of vascular headache in patients with CRS. To evaluate incidence of vascular headache in patients with CRS. Using descriptive study design, group of 100 patients with symptoms of CRS with headache were included in study. Patients underwent surgical management and 3% managed medically...

Objectives: Pathophysiology of chronic rhinosinusitis (CRS) is very complex and has not yet been clearly understood. To date, various factors have been researched to have relations with the pathogenesis of CRS, such as superantigens and biofilms. Recently, we found an unusual pathological finding in patients with CRS, and we called this new entity as bacteria ball (or bioball). In this study, we analyze the clinical characteristics of bacteria ball occurred in CRS. Methods: This study enrolled consecutive 247 patients with CRS who underwent functional endoscopic sinus surgery from January 2015 to August 2016...

BACKGROUND: Having one hand occupied with the endoscope is the major disadvantage for the surgeon when it comes to functional endoscopic sinus surgery (FESS). Only the other hand is free to use the surgical instruments. Tiredness or frequent instrument changes can thus lead to shaky endoscopic images. METHODS: We collected the pose data (position and orientation) of the rigid 0° endoscope and all the instruments used in 16 FESS procedures with manual endoscope guidance as well as robot-assisted endoscope guidance...
