OBJECTIVES: This study aimed to radiologically evaluate the influence of inflammatory changes in frontal recess cells on frontal sinusitis. METHODS: A total of 93 patients (186 sides) who underwent primary sinonasal surgery at Hyogo College of Medicine were enrolled in 2015 and 2016. Opacification of agger nasi, fronto-ethmoidal, ethmoid bulla, suprabullar and frontal bulla cells was determined by pre-operative computed tomography and its influence on frontal sinusitis was investigated...

Objective To define relationships between the frontal sinus opening, ostia of other frontal recess cells, and endoscopic landmarks and to develop a clinically useful framework to guide frontal sinus surgery. Study Design Retrospective review. Setting Tertiary care academic referral center. Methods Adult patients with computed tomography (CT) without sinonasal pathology were included. Virtual endoscopy (using OsiriX) and corresponding CT reconstructions were used to identify all visible ostia in the frontal recess and characterize their positions in spaces between the uncinate/agger nasi (U), bulla ethmoidalis (EB), and middle turbinate (MT)...

The frontal sinus outflow pathway is complex and can be influenced by the configuration of the uncinate process (UP). The UP can attach superior to the lamina papyracea, skull base, and middle turbinate. The factors associated with superior attachment remain unclear. This study analyzed the relationships between different types of superior UP attachment and characteristics of the surrounding structures including the agger nasi cell, skull base, and middle turbinate. This retrospective study utilized computed tomography images of 836 sides with identifiable sinus structure from 434 Taiwanese patients...

The aim of this study is to describe the morphology of frontal recess area with its anatomical variations and to reveal if frontal recess morphology and the anatomical variations related to that region have effects on the pneumatization of the frontal sinuses. The frontal sinus and recess morphometry of 136 sides of 68 dry skulls were evaluated on multislice high-resolution computed tomography. The relationships between frontal sinus and frontal recess measurements were analyzed by correlation and linear regression analysis...

Treatment of frontal sinus using surgery is complicated owing to the complex anatomical structure of the sinus region. The aim of the present study was to investigate the efficacy and safety of Draf IIb endoscopic frontal sinus surgery treatment for frontal sinus lesions using the agger nasi approach on 19 patients (28 left or and right nasal cavities). A 10-12 mm excision of the upper frontal maxilla was performed for endoscopic resection between the middle turbinate and lateral nasal wall. No serious complications in frontal sinus surgery treatment for the removal of the frontal sinus were observed...

To evaluate the incidence of anatomical variations in sinonasal area by nasal endoscopy and CT scan paranasal sinuses and to correlate the anatomical variations in sinonasal area with extent of disease. The present study was conducted on 40 patients of chronic sinusitis. All the patients underwent CT scan paranasal sinus axial and coronal view and nasal endoscopy. The most common anatomical variations were agger nasi cells (80 %), deviated nasal septum (72.5 %) and concha bullosa (47.5 %). Other anatomical variations seen in sinonasal region were uncinate process variations, paradoxical middle turbinate, haller cells, accessory ostia of maxillary sinus, multiseptated sphenoid...

BACKGROUND: Given the lack of basic diagnostic criteria for empty nose syndrome (ENS), we sought to define whether consistent radiographic characteristics could be identified to aid in the development of such criteria. METHODS: Computed tomography (CT) scans were collected from 65 patients diagnosed with ENS, patients with a history of submucosal inferior turbinate reduction (ITR) without ENS, and patients without a history of sinonasal procedures. Measurements were taken at the level of the nasolacrimal duct, including the inferior turbinate (IT) mucosal thickness, and the widest distances between septum-IT, nasal floor-IT, lateral nasal wall-IT, and septum-lateral nasal wall...

OBJECTIVE: Although sinonasal anatomic variations have been postulated as a risk factor for sinus disease, the role of anatomic abnormalities in the pathogenesis of nasal polyps is still unclear. This study was conducted to examine the association of sinonasal polyposis with anatomic variations. METHODS: The paranasal sinus computerized tomography scans of 155 patients with sinonasal polyposis were examined retrospectively from January 2012 to 2014 in a tertiary care hospital...

PURPOSE: The endoscopic bidimensional vision offered by the endoscope during endoscopic sinus surgery involves difficulty in visualizing surgical field depth which makes it difficult to learn this surgical technique and makes it necessary for the endoscopic surgeon to mentally create a three-dimensional (3D) picture of the paranasal sinuses anatomy. In particular, frontal recess surgery requires good knowledge of its anatomic position, also since it is necessary to use angled endoscopes, which distort the view, and angular instruments which are difficult to use...

It is necessary for the surgeon to be familiar with frontal recess anatomy during an endoscopic approach to the frontal sinuses. The aim of this study was to evaluate the prevalence of frontal recess cells in Japanese adults as well as the association between the frontal recess and the location of the anterior ethmoidal artery (AEA). The frontal recess cells and the AEAs were retrospectively evaluated in CT scans of the nasal and paranasal sinuses for 89 patients. The prevalence of agger nasi cells was 90.7%...

BACKGROUND: The incidence and potential disease impact of paranasal sinus anatomic variants in patients with recurrent acute rhinosinusitis (RARS) has important implications for management, including surgery, but is incompletely defined. METHODS: A retrospective review of 26 patients with RARS who had undergone computed tomography (CT) was performed. Patient demographics, RARS severity and comorbidities were reviewed. CT scans were reviewed for the incidence of anatomic variants in all patients...

OBJECTIVE: To describe the prevalence of frontoethmoid cells and superior uncinate process attachment in pediatric patients with sinonasal symptoms. METHOD: Fifty high-resolution computed tomographies of the paranasal sinuses for pediatric patients were evaluated for the presence of frontoethmoid cells and uncinate process insertion. The computed tomographies were randomly collected for patients with sinonasal symptoms (age range, 4-15 years) at our clinic. The prevalence of these cells was compared against age group and type of uncinate process...

The aim of this study is to assess the pneumatization of the paranasal sinuses (PNS) and other parts of temporal bone such as mastoid air cells and to investigate if there was any association between the aeration of these structures among the three major ethnic groups in Malaysia (Malay, Chinese, Indian) as this would be representative of Asia. A retrospective review of 150 computed tomography (CT) scans of PNS and temporal bones was done and analysed. The pneumatization of each area was obtained and compared using statistical analysis...

REVIEW

PURPOSE OF REVIEW: An accurate understanding of the anatomy of the lateral nasal wall is key to achieving complete exposure of the lacrimal sac during endonasal dacryocystorhinostomy (EnDCR) and the avoidance of complications such as basal skull fracture and orbital fat prolapse. This review provides a comprehensive summary of the clinical and cadaveric anatomical studies of the lateral nasal wall to date and their application to endonasal lacrimal surgery. RECENT FINDINGS: The maxillary line and the axilla of the middle turbinate are the major landmarks commonly utilized by lacrimal surgeons to localize the lacrimal sac...

OBJECTIVE: The purpose of this study was to determine the incidence of sinonasal anatomic variants and to assess their relation to sinonasal mucosal disease. MATERIALS AND METHODS: A retrospective evaluation of 192 sinus CT examinations of patients with a clinical history of rhinosinusitis was conducted. The CT scans were evaluated for the presence of several anatomic variants of the sinonasal cavities, and the prevalence of each variant was calculated. Prevalences of all sinonasal anatomic variants were compared between patients who had minimal to no apparent imaging evidence of rhinosinusitis and those who had radiologic evidence of clinically significant rhinosinusitis...
