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.

Abstract Introduction: For Functional Endoscopic Sinus Surgery (FESS), the surgeon needs an accurate depiction of the anatomy of paranasal sinuses and their variations. Computed tomography (CT Scan) fulfills this requirement by providing detailed anatomy, the anatomical variants, and the extent of the disease in and around the Para nasal sinuses. The aim of this study is to show the anatomy of the Frontal sinus as delineated by the computed tomography. Materials and Methods: STUDY DESIGN: Cross section Descriptive Study. Out of 337 patients above 12 years of age who were referred for computed tomography of paranasal sinuses in the Dept. of Radio- Diagnosis, Govt. Medical College and Hospital from December 2015 till October 2017, 200 adults(males and females) were randomly selected.Of the 200 subjects studied 37(18.5%) subjects had hypoplastic/ non or poorly pneumatised frontal sinuses of which 31 (15.5%) were bilateral and 6 (3%) were unilateral i.e. on right side. Observations and results: Intra frontal cell were seen in about 64 (32%) subjects of which 26 (13%) on right side, 24 (12%) were on left side and 14 (7%) were bilateral. Extension of pneumatisation into crista galli was seen in 16 (8%) subjects and into orbital roof was seen in 6 (3%) subjects. Conclusion: The findings in this study show that anatomical variations in the Para nasal sinuses and nasal cavity are common. Computed tomography is fundamental radiologic investigation for diagnosis of the Sino nasal lesions or pre and post-surgical assessment.

Background: The standard imaging in the assessment of the para-nasal sinuses is currently computed tomography scanning. This provides an applied anatomical view of the area as well as the common anatomical variants. The advancement and improvement of computed tomography scans has provided for a comprehensive evaluation of patients' para-nasal sinuses, allowing Functional Endoscopic Sinus Surgery surgeons to operate with a guide chart. Objectives: To study normal anatomical variations in para-nasal sinuses using Computed Tomography. Material and Methods: This research took place in a tertiary healthcare center's radiology department over the course of two years. Axial para-nasal sinuses cuts were taken using a multi-slice (128 slice scanner), followed by coronal and sagittal reconstruction. Results: The most common anatomic variation, according to the findings, was nasal septal deviation. The rarest variation in our sample was Haller cell and pneumatized septum. There was also a close connection between unilateral Concha bullosa and contra-lateral septal deviation, as evidenced by the research. Conclusion: A wide range of lesions can affect the para-nasal sinus area. Normal anatomical differences and congenital abnormalities in this area are significant because they can have pathological consequences or cause difficulty/complication during surgery.

AbstractWe report the case of a 57-year-old patient with a presumed developmental anomaly of the medial orbital wall. The resultant protrusion of orbital contents into the ethmoidal complex was clearly demonstrated on coronal computed tomography (CT) scans of the paranasal sinuses. This anomaly presents a high risk of iatrogenic injury to the medial rectus and orbit during functional endoscopic sinus surgery and has not previously been described.

<p class="abstract">Anatomic variations of the paranasal sinuses can lead to various diseases per se. The paranasal sinus anatomy should be carefully examined prior to performing endoscopic sinus surgery in terms of both existent pathologies and anatomic variations. The anatomy of the paranasal sinuses and its variations have gained importance, along with advances in coronal paranasal sinus computed tomography and extensive use of endoscopic sinus surgery. Rhinolith is a mass resulting from calcification of an endogenous or exogenous nidus within the nasal cavity. It is an uncommon disease that may present asymptomatically or cause symptoms like headache and nasal obstruction. A 24 year old woman was admitted in ENT department of GGS Medical College and Hospital, Faridkot with complaints of nasal obstruction, anosmia and headache persisting for 5 years. Right sided rhinolith was detected on anterior rhinoscopy. Bilateral concha bullosa with right sided rhinolith was reported on preoperative paranasal computed tomography scan. It is known that the paranasal sinuses have a number of anatomical variations. Sometimes severe anatomic variations predispose to rhinosinusitis. Herein we report a rare case, along with a review of the literature, to emphasize that severe anatomical variations should not be ignored.</p>
