AbstractObjectives:This study assessed the utility of current sialendoscopes in the paranasal sinuses in a cadaveric model and evaluated novel uses for sialendoscopes.Methods:Currently available sialendoscopes were used for visualisation and performing interventions in the paranasal sinuses. Ten cadaver heads were studied before and after dissection. Outcomes included ostia identification, sinus cannulation, success of mucosal biopsy collection and image clarity.Results:Marchal and Erlangen sialendoscopes were found to be effective for both visualising and cannulating the sphenoid sinuses before and after dissection. Both types demonstrated poor maxillary ostia visualisation without dissection, but did allow treatment after antrostomy. Larger diameter sialendoscopes were associated with the lowest image distortion during maxillary ostia assessment. Mucosal biopsy collection within the sphenoid sinus, but not in the maxillary sinus, was possible before dissection.Conclusion:Sialendoscopes can be used for visualisation and performing interventions in the sinonasal cavity, but their utility is mainly limited to the sphenoid sinus. They may be considered a minimally invasive method for drug delivery and/or biopsy collection in the post-operative setting for all sinuses. Design improvements are suggested.

AbstractThe anatomy of the sphenoid sinus, as it relates to endoscopic sinus surgery, was studied in 93 cadaver heads (186 sphenoid sinuses) using endoscopic dissections as well as sagittal sections. The relationship of the sphenoid sinuses to the carotid artery, optic nerve, floor of sella turcica, as well as other important structures, were verified and discussed. The recesses of the sinus as well as its ostium and accessory septa and crests were described and their clinical importance was discussed. Pertinent measurements were included wherever appropriate.

BACKGROUND: The purpose of our study was to assess the prevalence of different patterns of pneumatization in the sphenoid sinuses as detected on the computed tomography (CT) images of paranasal sinuses of the patients presenting with various pathologies. This is a retrospective radiological study of CT im MATERIALS AND METHODS: ages of paranasal sinuses, done at Radio diagnosis department of a Tertiary care hospital. The study comprised CT images of 500 patients in the age range of 18-75years who were referred for CT scan of paranasal sinuses for various pathologies between the period of July 2018 and July 2019. All images of paranasal sinuses had been acquired following a standardized protocol in axial plane. Their reconstructed images in axial, coronal and sagittal planes were evaluated, using Osirix software, for the extent and different patterns of sphenoid sinus pneumatization. The Images of sphenoid sinuses were assessed for the posterior, lateral and anterior extension of their pneumatization The sphenoid sinuses pneumatization patterns in the RESULTS: descending order of prevalence were complete sellar (75.0%), incomplete sellar (22.6%), presellar (2.4%) and conchal (0%). The clival extensions was seen in 75% of patients and lateral extension sides in 49.1% patients. Lateral recesses as assessed on coronal images was seen in 49.1 % of cases with the prevalence in descending order being extension into pterygoid process 59.8 %, greater wing of sphenoid 9.2 %, full lateral 41% and lesser wing (anterior clinoid process) 19.3%. The pure forms were relatively less common and combined forms being more common. A preoperative review of the sphenoid anatomy should allow for safer endo

Improving the effectiveness of treatment of chronic rhinosinusitis (CRS) is a priority task of modern otorhinolaryngology, not only domestic, but also foreign. This interest in the problem is due to the widespread prevalence of this pathology. In different countries, the criteria for accounting for the incidence, algorithms for the diagnosis and treatment of rhinosinusitis differ significantly, and for CRS these differences are more pronounced than for acute. A retrospective analysis of the structure and prevalence of ENT diseases according to inpatient observations for 5 years showed that chronic diseases of the nose and paranasal sinuses (SNP) occupied a priority place among hospitalized patients (45.8 ± 0.9% and 55.5 ± 1,0%). In the structure of the main diseases of SNP, the largest share in the adult population is occupied by inflammation of the maxillary sinus (HPP), in which there is an annual increase in the incidence of 1-1.5%, the second most frequent is inflammation of the ethmoid labyrinth cells, then the frontal and sphenoid sinuses.
