AbstractBackground:Chronic rhinosinusitis is commonly treated by functional endoscopic sinus surgery involving excision of the uncinate process and opening of the osteomeatal complex.Methods:Computational fluid dynamics were used to compare nasal airflow after two different surgical interventions which involved opening the paranasal sinuses, excising the ethmoid sinus, and excising or preserving the uncinate process, in a cadaveric head model. Cross-sectional computed tomography images were obtained before and after the interventions. Imaging data were used to prepare computer simulations, which were used to assess the airflow characteristics of the nasal cavities and paranasal sinuses during inspiration and expiration, before and after intervention.Results:Significantly larger nasal cavity airflow velocity changes were apparent following the uncinate process excising procedure. Nasal cavity airflow distribution remained relatively unchanged following the uncinate process preserving procedure. There was a significantly greater increase in airflow volume following the uncinate process excising procedure, compared with the uncinate process preserving procedure.Conclusion:Preservation of the uncinate process may significantly reduce the alteration of nasal cavity airflow dynamics occurring after functional endoscopic sinus surgery for chronic rhinosinusitis.

Background The aim of this study was to report objective and subjective outcomes after revision sinus surgery (RESS) for chronic rhinosinusitis (CRS). Methods We performed a retrospective analysis of prospectively collected data in 125 patients requiring revision functional endoscopic sinus surgery after failing both maximum medical therapy and prior sinus surgery for CRS. Patients were seen and treated over a 3-year period (1999–2001) in a tertiary rhinology setting. Computed tomography (CT) scans were graded as per Lund-MacKay and patient symptom scores were recorded using the Sinonasal Outcome Test 20 (SNOT-20) instrument. Individual rhinosinusitis symptoms were evaluated on a visual analog scale (0–10) before and after surgery. All patients had a minimum 2-year follow-up. Results The mean number of prior sinus procedures was 1.9 ± 0.1 (range, 1–7) and the mean preoperative CT grade was 13.4 ± 0.7. Patients with asthma and polyposis had higher CT scores than those without these processes. Preoperative mean SNOT-20 and endoscopy scores were 30.7 ± 1.3 and 7.3 ± 0.4, respectively. At the 2-year follow-up, mean SNOT-20 and endoscopy scores improved to 7.7 ± 0.6 and 2.1 ± 0.4, respectively (p < 2.8 X 10-10). At 12-month follow-up, each individual symptom score decreased significantly. Overall, 10 patients failed RESS and required additional surgical intervention for an overall failure rate of 8.0%. All patients who failed RESS had nasal polyposis. Conclusion Revision functional endoscopic sinus surgery benefits patients that fail maximum medical therapy and prior sinus surgery for CRS by objective and subjective measures.

Nose And Sinuses

The advent of functional endoscopic sinus surgery (FESS) has revolutionized the treatment of chronic sinusitis over the last decade. Although it has been well-established that FESS is more efficacious than conventional surgery, the lack of a quantifiable means of assessing results remains one of the major shortcomings of the technique, and hence a source of criticism. Since the pathophysiology of chronic sinusitis is intimately related to the mucociliary mechanism of the nose and sinuses, it seems logical to use this parameter as a yardstick of success. We undertook a prospective, controlled study of 40 patients and measured their “saccharin times” before and after surgery. The results show a marked reduction in clearance times postoperatively, corresponding well with improvement in symptom profile. We therefore propose this technique as a simple, safe and reliable method of assessing the results of surgery. Furthermore, the method could act as a preoperative indicator of ciliary motility disorders, as the prognosis in these patients is distinctly poor.

AbstractObjectives:To analyse the radiological features of the bony nasolacrimal duct before and after functional endoscopic sinus surgery, and document the incidence of surgically induced dehiscence.Methods:A retrospective case series analysis was conducted of 63 consecutive patients who underwent uncinectomy as a part of 118 functional endoscopic sinus surgical procedures. All patients underwent pre- and post-operative computed tomography scans. Axial computed tomography images at the level of maxillary sinus were evaluated for the presence of bony nasolacrimal duct dehiscence, osteitis and completeness of uncinectomy.Results:The rate of nasolacrimal duct dehiscence prior to surgery was 6.8 per cent (8 out of 118 cases). Nasolacrimal duct dehiscence as a consequence of surgery was observed in 3.3 per cent of cases (4 out of 118), with a further 4.2 per cent (5 out of 118) showing post-operative reactive bony change of the nasolacrimal duct in the absence of dehiscence.Conclusion:The incidence of nasolacrimal duct injury observed was much lower than that previously reported in the literature.

Six patients between the ages of 6 and 22 years old with cystic fibrosis were found to have mucoceles of the paranasal sinuses. Four were male and two were female. They experienced nasal obstruction, purulent rhinorrhea, and anosmia, but none had fever or pain. Nasal endoscopy and coronal computerized tomography scans revealed the lateral nasal wall to be displaced medially against the septum. Functional endoscopic sinus surgery revealed large cystic spaces filled with thick yellow-green mucus. Postoperatively most patients are able to smell and breathe through their noses. The mucocele probably begins as an obstructed anterior ethmoid cell, which then enlarges and obstructs the osteomeatal complex, which further impairs drainage of the other sinuses into this area.

Rare Phenomenon

Functional endoscopic sinus surgery (FESS) is most commonly used in chronic rhinosinusitis treatment. This method is also applicable to other diseases, including the treatment of symptomatic ectopic teeth. Ectopic teeth are a quite rare phenomenon. They may appear within the facial region, as well as in other parts of the body. The article describes two cases of ectopic teeth appearing within the nose area and paranasal sinuses, there endoscopic surgery has been used in the extraction, which resulted in the remission of symptoms.

Nose And Paranasal Sinuses

One of the main objectives of our 3-dimensional (3D) computer-assisted functional endoscopic sinus surgery was to design a computer-assisted 3D approach to the presurgical planning, intraoperative guidance, and postoperative analysis of the anatomic regions of the nose and paranasal sinuses. Such an extremely powerful approach should allow better insight into the operating field, thereby significantly increasing the safety of the procedure. The last step to implementing the technology in the operating room was to connect the computer workstations and video equipment to remote locations by using a high-speed, wide-bandwidth computer network. During patient preparation, the surgeon in the operating room consulted remote experienced and skillful surgeons by viewing CT images and 3D models on computer workstations. The surgeon and consultants used software for CT image previews and 3D model manipulations on top of collaboration tools to define the pathosis, produce an optimal path to the pathosis, and decide how to perform the real surgical procedure. With tele-flythrough or tele-virtual endoscopy rendered through the use of 3D models, both surgeons can preview all the characteristics of the region (ie, anatomy, pathosis) and so predict and determine the next steps of the operation. This ensures greater safety thanks to the operation guidance and reduces the possibility of intraoperative error. The duration of the teleconsultation is thus shortened, which may prove the greatest benefit of tele-3D computer-assisted surgery. If this method were used, clinical institutions would spend less money for telesurgical consultation.

BACKGROUND The paranasal sinuses (PNS) have various anatomical difference. Computed tomography (CT) is an excellent means of providing anatomical information of this region, disease extent, assisting endoscopic evaluation and guiding treatment. Functional endoscopic sinus surgery (FESS) has become an increasingly popular treatment for chronic sinus diseases. CT of the paranasal sinuses has become a roadmap for FESS. The present study focuses on the assessment of the efficacy, safety and benefits of functional endoscopic sinus surgery in cases of maxillary pathologies and also study the anatomical variations in maxillary sinus in computed tomography and its usefulness in planning and management of chronic sinonasal diseases. METHODS It was a prospective study and a total of 80 patients were included in this study from July 2019 to June 2020 in the Otolaryngology Department, KIMS, Karad. Standard surgical steps were applied in each case according to the extent of disease. All patients underwent standard post-operative care. All findings were recorded and studied. RESULTS Total number of patients were 80. Of which, 31 (38.75 %) patients were operated for ethmoidal polyp, 24 (30 %) for chronic rhinosinusitis, 10 (12.5 %) for antrochoanal polyp, 9 (11.25 %) for rhinosporidiosis and 6 (7.5 %) for inverted papilloma. Postoperative complications were periorbital echymoses (13 %), synechiae (2.5 %), epiphora (2.5 %), infection (2.5 %), hemorrhage (4 %). Complete relief of symptoms were noted in 81.67 % cases. CONCLUSIONS Successful outcome and patient satisfaction post treatment can be obtained by careful evaluation and patient selection by history, examination and most importantly, proper imaging of the sinuses.
