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.

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.

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.

AbstractBackground:Functional endoscopic sinus surgery is recognised to have a significant complication profile (e.g. blindness, cerebrospinal fluid leak and intracranial sepsis). Pre-operative computed tomography imaging is considered mandatory for surgical planning to reduce intra-operative risk. A radiological report is the ‘gold standard’ in image interpretation; however, because of a lack of otolaryngological or radiological guidance, its contents may be variable. By surveying practising otolaryngologists, this study aimed to provide some guidance which may be used by radiologists to produce more surgically relevant radiological reports.Method:A prospective questionnaire was distributed to the ENT-UK panel.Results:A total of 117 consultant members of the panel completed the survey. Twenty-nine per cent indicated that they were uncomfortable interpreting all areas of the computed tomography scan. Greatest importance was given to areas including the ethmoid roof (dehiscence, asymmetry and angle), lamina papyracea (dehiscence) and sphenoid sinus (carotid canal dehiscence and optic nerve relationships).Conclusion:Functional endoscopic sinus surgery is commonly performed by non-subspecialist rhinologists. The information obtained from this study can be used by radiologists to improve report relevance, particularly for the generalist ENT surgeon. This contributes to improving patient safety and helps avoid medicolegal litigation when complications arise.

Chronic Maxillary Sinusitis

AbstractThe role of the anterior ethmoids in the pathogenesis of chronic maxillary sinusitis is still a subject of controversy. Although the symptoms of maxillary sinusitis may be clinically dominant, many previous studies have showed that the origin of this disease was, in most cases, located within the anterior ethmoid region.This study included 100 Egyptian patients, suffering from chronic maxillary sinusitis (confirmed by maxillary sinoscopy), who were subjected to ‘systematic nasal endoscopy’. It was found that all cases of chronic maxillary sinusitis were associated with anatomical variations and/or pathological abnormalities of ‘the ostiomeatal area’. It is recommended, therefore, that during the diagnosis and treatment of chronic maxillary sinusitis, attention should be given to the region of the middle meatus and anterior ethmoid complex (or ‘ostiomeatal area’) for any anatomical variations and/or pathological abnormalities in order to avoid recurrence of maxillary sinusitis. This is the basis of the procedure of functional endoscopic sinus surgery.
