“…The study by showed the incidence of HC 3.5% which is close to our result [10]. The incidence of Onodi cells in our study is 2.7% which is lowest incidence in comparison with other studies which showed the incidence of OC ranges from 8-13% [11]. These cells also known as sphenoethmoidal cells, they are the most posterior ethmoid air cells that extend laterally and located anterosuperior to sphenoid sinus [5].…”

“…Among The anatomical variants the most frequent variant was deviated nasal septum which can be bony, cartilaginous, or combination. The divergence of septum from the midline causes lateral displacement of middle conch leading to nasal obstruction [11]. Our study also shows 14.3% of patients with nasal septum spur, which is bony deformity that may obstruct the nasal air flow, and may be associated nasal septal deviation.…”

Introduction: In the era of Functional Endoscopic Sinus Surgery, precise knowledge of paranasal sinus anatomy and variations are essential for the surgeon. The multi-slice computed tomography is the imaging modality of choice provides accurate evictions of the anatomy, the anatomical variants and the extent of the disease in paranasal sinuses, such a method allowing their accurate identification with high anatomical details. Some of these variants may predispose to sinus diseases or become of high risk for injuries and complication during surgical procedure, therefore, the study of anatomic variants of paranasal sinuses is important in the preoperative endoscopic surgery. Objectives: The purpose of this study is to assess the frequency of anatomic variants and their clinical importance. Materials and methods: This retrospective study was conducted at the Department of Radiology, Benghazi Medical Center, Benghazi, Libya. Data comprised the paranasal sinus computed images of 112 patients (46 males and 66 females) analyzed for the presence of anatomic variants and associated sinus pathology. Results: Our results showed that the most common anatomical variants was deviated nasal septum (60.7%) with slight higher incidence on left side, followed by concha bullosa (22.3%), other variants found were absent frontal sinus (18.8%), Nasal spur (14.3%) , Agger nasi cell (16.1%), Haller cell (5.4%), Onodi cell (2.7%), accessory ostia of maxillary sinuses (10.7%), accessory middle nasal concha (1.8%), paradoxical middle turbinate (1.8%), nasal septum pneumatization (5.4%), Crista galli pneumatization (2.7%), pneumatization of hard palate (1.8%) and pneumatization of clinoid process (6.3%). (53.6%) patients suffered from sinusitis, the results showed that the most common sinus involved was maxillary sinus. Conclusion: Anatomical variations of PNS are quite common. Analysis of every paranasal CT scan obtained for sinusitis for the presence of different anatomic variants is of questionable value unless endoscopic surgery is planned to reduce the risk of intraoperative complications.

“…Recently, diagnostic nasal endoscopic evaluation of the nose and paranasal sinuses is a routine component for evaluating patients with evidence of suspected chronic sinusitis and the patients with significant findings are evaluated with Computed Tomography (CT) of the paranasal sinuses. 9 Diagnostic Nasal Endoscopy (DNE) and computerised tomography plays a role in diagnosis and to identify the variations in paranasal sinuses. Precise descriptions of anatomical variations are very important in achieving perfect diagnosis and successful endoscopic sinus surgeries.…”

BACKGROUND Chronic Suppurative Otitis Media (CSOM) is the chronic inflammation of the middle ear cleft mucosa, which is characterised by irreversible changes in it with a history of ear discharge for more than 3 months through a permanent tympanic membrane defect. Chronic suppurative otitis media is of two types tubotympanic (mucosal) and atticoantral (squamous). Tubotympanic type (mucosal) is mainly due to infection from the oropharynx and the nasopharynx, which travels into the middle ear via the eustachian tube, whereas atticoantral type (squamous type) is due to cholesteatomatous lesions. The prevalence of CSOM was 4.1 percent (3.1%-unilateral and 1.0% bilateral disease). Both otitis media and sinusitis are the most common pediatric diagnoses and they share many common characteristics. The aim of the study is to prove focal sepsis of chronic otitis media, tubotympanic type sinusitis and there is an improvement in middle ear mucosal disease status after functional endoscopic sinus surgery.

“…This is similar to various literatures in the past. Narendra kumar and Subramaniam 9 who Presented it as 76% whereas Turnaet al 10 The strengths of the study are along with a study of incidence of various individual anatomical variants, detailed knowledge was gained about concomitant existence of two or more variations in the same patient. Limitations being, since it included only those people who presented to the ENT OPD with complaints regarding nose and paranasal sinuses, there might be a bias in extending the results to the general population.…”

Introduction: The anatomy of organs of ENT is a herculean task to understand and evaluate in the whole human anatomy. Knowledge about the possible variabilities is never complete, since there is always a scope to understand better and know more. Many studies have been undertaken in the past to understand better the already existing knowledge about the various anatomical details in the nose and paranasal sinuses causing chronic rhinosinusitis. The present study was carried to know the details of variations in anatomy of nose and paranasal sinuses causing chronic sinusitis. Material and Methods: A Cross sectional study conducted over a period of two years, in patients presenting to ENT OPD with symptoms and signs and chronic rhinosinusitis, in a setting of tertiary hospital, with the requisite investigative protocols. Patients meeting the inclusion criteria were included in the study and subjected to the prescribed interventions. Results: Observations gathered from this study are-of the 65patients included, 86.1% had septal deformities, 58.4% had Concha bullosa, 52.3% had Agger Nasi, 15.3% had Haller Cell, 13% had Paradoxical Middle Turbinate, 4.6% had Everted Uncinate Process, 3% had Enlarged Bulla. Conclusion: Sinonasal anatomy is different in each individual, with various combined variations also.
