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.

Tomography Scan

Eighteen patients were operated on by functional endoscopic sinus surgery who had no ostiomeatal unit obstruction on computed tomography scan and had unremarkable paranasal sinuses. These patients also had no apparent ostiomeatal unit obstruction on diagnostic nasal endoscopy. Data were collected on these patients regarding the impact of very limited functional endoscopic sinus surgery on their principal complaint of recurrent sinusitis with facial pain/headache thought to be of sinogenic origin. Sixteen patients (88.9%) had a reduction in the number of sinus infections requiring antibiotic therapy. This reduction was significant at p < 0.0001. Twelve of 14 patients whose facial pain/headache was believed to be of sinogenic origin had a significant reduction in severity (95% confidence interval, 49.2% to 95.3%). We discuss the role of reversible nasal mucosal disease in the pathophysiology of recurrent rhinosinusifts in this patient population. This was a very small, select group of patients who had specific complaints and had had medical treatment failures. This therapy Is not recommended for every patient, but only a select few with classic complaints of sinus headaches or recurrent sinusitis and negative computed tomography scans.

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.

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.

The development of computed tomography and functional endoscopic sinus surgery has improved diagnosis and management of sinusitis. It has also renewed interest in the developmental anatomy of the paranasal sinuses. There are significant differences between adult and pediatric sinus anatomy, and to safely perform functional endoscopic sinus surgery in children, the surgeon must be aware of these differences. To define the developmental anatomy of the paranasal sinuses, we analyzed 145 computed tomograms from patients under 18 years of age. The study emphasized landmarks at the level of the maxillary sinus ostium. In addition, distances and angles from the nasal spine to various points in the sinuses were determined. The structures were identified and traced on a digitizing tablet. Means and standard deviations were calculated for each measure as a function of age. This study can aid a better understanding of sinus development in children and provide guidance to the endoscopic sinus surgeon.

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.
