According to the characteristics of endoscopic transnasal and transoral surgery for infratemporal fossa tumors, we divided and named subzones of the infratemporal fossa, to explore the approaches of endoscopic transnasal and transoral surgery for infratemporal fossa tumors, and to analyze their advantages and disadvantages. We retrospectively analyzed the clinical data of 36 patients with benign tumors of infratemporal fossa successfully resected through nose or mouth under endoscope, summarized and analyzed the localization characteristics of these tumors in infratemporal fossa, and made a subzone naming rule of infratemporal fossa. We also summarized the selection principles, advantages and disadvantages of endoscopic transnasal and transoral surgical approaches. Read More

Rosai-Dorfman disease (RDD) is a rare histiocytic disorder, usually presenting with massive lymphadenopathy. The involvement of extra nodal sites, bone and nodal sites like mediastinum are rare. Clinical data of three cases of extra nodal RDD who were admitted in our paediatric haemato-oncology unit were analysed in the last 5 years. Read More

The relationship between maxillary sinus pneumatization and respiratory-induced fluid mechanics remains unclear. The purpose of this study was to simulate and measure the respiratory-induced mechanical stimulation at the sinus floor under different respiratory conditions and to investigate its potential effect on the elevated sinus following sinus-lifting procedures. The nasal airway together with the bilateral maxillary sinuses of the selected patient was segmented and digitally modeled from a computed tomographic image. Read More

Background: Flaplessly placed one-piece mini dental implants (MDI) are an option to support maxillary overdentures. Evenly distribution of the implants over the atrophic alveolar process implies a risk of accidental sinus perforation in the posterior area which could induce sinus-related pathology.

Methods: Thirty-one patients received 5-6 maxillary MDIs. Read More

Introduction: To determine the frequency and risk factors of maxillary sinusitis of endodontic origin (MSEO) on posterior maxillary teeth evaluated using dynamic navigation and a novel filter of cone-beam computed tomography (CBCT).

Material And Method: CBCT scans of 453 patients (814 teeth) were selected. Data were divided into four groups: 1) root canal treatment (RCT); 2) relation of the root apex to the maxillary sinus, 3) apical periodontitis (AP); 4) maxillary sinus inflammation - no inflammation, periapical osteoperiostitis, periapical mucositis, partial obstruction, total obstruction.
