This was a study of the effect of functional endoscopic sinus surgery (FESS) on the ciliary regeneration of maxillary sinus mucosa in patients with chronic maxillary sinusitis, using objective quantitative methods. Twenty specimens from the mucosa of both the superolateral wall and the ostium of the maxillary sinus were sampled during FESS and then six to 12 months later. They were light examined first by light microscopy and then by scanning electron microscopy in combination with image analysis software in order to study the cilia under higher magnification and to calculate proportion of the field that was ciliated. Samples were taken and studied at Cairo University hospital. This study showed that the maxillary sinus mucosa in chronic sinusitis is capable of regeneration and could return towards normal with the improvement of ventilation and drainage of the maxillary sinus following FESS. There were no significant changes in the degree of glandular hyperplasia, goblet cells or pathological glands after surgery.

Introduction. Silent sinus syndrome is a rare condition, characterized by spontaneous and progressive enophthalmos and hypoglobus associated with atelectasis of the maxillary sinus and downward displacement of the orbital floor. Patients with this syndrome present with ophthalmological complaints, without any nasal or sinus symptoms. Silent sinus syndrome has a painless course and slow development. It seems to be a consequence of maxillary sinus hypoventilation due to obstruction of the ostiomeatal unit. The CT scan findings are typical and definitely confirm the diagnosis of silent sinus syndrome. Case report. We present the case of a 35-year-old woman, with no history of orbital trauma or surgery. She had slight righthemifacial pressure with no sinonasal symptoms. The patient had no double vision nor other ophthalmological symptoms. The diagnosis of silent sinus syndrome was based on the gradual onset of enophthalmos and hypoglobus, in the absence of orbital trauma (including surgery) or prior symptoms of sinus disease. On paranasal CT scans there was a complete opacification and atelectasis of the right maxillary sinus with downward bowing of the orbital floor. The patient was treated with functional endoscopic sinus surgery, with no orbital repair. Conclusion. Silent sinus syndrome presents with orbithopaties but is in fact a rhinologic disease, so all ophthalmologists, rhinologists and radiologists should know about it. The treatment of choice for silent sinus syndrome is functional endoscopic sinus surgery, which should be performed with extra care, by an experienced rhinosurgeon.

Functional endoscopic sinus surgery concentrates primarily on the removal of ostiomeatal complex disease. When required, maxillary sinus ostioplasty is performed. However, surgical widening of a sinus ostium is contrary to common precepts. A study therefore was performed to reevaluate the effects of antrostomies and of intrasinus mucosal removal. Widening of the natural ostium, a separate antrostomy at some distance from the ostium, or radical mucosal removal was performed on 30 rabbits. Fifteen sinuses were used as controls. After 6 to 8 weeks the status of the sinus mucosa and mucociliary clearance was studied. The study confirmed that mucociliary clearance continued toward the natural ostium following inferior antrostomy. Following widening of the natural ostium, mucociliary clearance through the ostium redeveloped in 11 of 18 sinuses but was typically imperfect. There were no cases of ostial closure; however, the incidence of infection was significantly higher in all three experimental groups than in the control group.

Background The aim of this study was to evaluate effects of functional endoscopic sinus surgery (FESS) on transient nasal aerodynamic flow patterns using computational fluid dynamics (CFD) simulations. Methods A three-dimensional model of the nasal cavity was constructed from CT scans of a patient with FESS interventions on the right side of the nasal cavity. CFD simulations were then performed for unsteady aerodynamic flow modeling inside the nasal cavity as well as the sinuses. Results Comparisons of the local velocity magnitude and streamline distributions inside the left and right nasal cavity and maxillary sinus regions were presented. Because of the FESS procedures in the right nasal cavity, existences and distributions of local circulations (vortexes) were found to be significantly different for the same nasal airflow rate but at different acceleration, deceleration, or quiet phases in the maxillary sinus region on the FESS side. Because of inertia effects, local internal airflow with circulation existences was continuous throughout the whole respiration cycle. With a larger peak inspiration flow rate, the airflow intensity inside the enlarged maxillary sinus increased significantly. Possible outcomes on functional performances of the nose were also examined and discussed. Conclusion Surgical enlargements of natural ostium of the maxillary sinus will change the aerodynamic patterns inside the main nasal cavity and maxillary sinus regions, which may affect normal nasal physiological functions. Local inertia effects play more important roles for the internal nasal airflow pattern changes and thus such conventional FESS procedures should be carefully planned.

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.
