Introduction: Middle turbinate overlying the middle meatus is the most important anatomic area in the lateral wall of the nose. It is a thinsheet of bone which curves in different planes very similar to a dried leaf. Paradoxical Middle Turbinate (PMT) is the abnormal curvatureof middle turbinate, where the convex surface faces laterally instead of its usual medial curvature and may block the drainage pathway ofmiddle meatus. The present study aimed at observing the prevalence of the paradoxical middle turbinate in the adult population of Bihar. Subjects and Methods: This was a retrospective st

Background Endoscopic sinus surgery is performed for many reasons, most commonly for chronic rhinosinusitis refractory to medical treatment. A paradoxical middle turbinate is an anatomic variant that can hinder endoscopic access to the sinuses. No publication has addressed how to surgically treat a paradoxical middle turbinate. Method We present a basic endoscopic surgical approach to conservatively resect a paradoxical middle turbinate in order to improve access to the middle meatus and the sinuses while preserving support and function.

Chronic rhinosinusitis (CRS) is a prevalent inflammatory condition of the nasal and paranasal sinuses lasting more than 12 weeks. Anatomical variations of the middle turbinate, particularly concha bullosa and paradoxical curvature, have been proposed as potential contributing factors to CRS by affecting sinus ventilation and mucociliary clearance. This study aims to evaluate the prevalence of middle turbinate variations in patients with CRS using computed tomography (CT) imaging.

The accuracy of clinical examination in predicting radiologic paranasal sinus disease was investigated. Two hundred forty-seven patients who underwent endoscopic sinus surgery over a 4-year period were clinically and radiologically staged prior to surgery. A clinical staging system was developed utilizing fiberoptic intranasal examination to adequately visualize the anterior and posterior ostiomeatal complex structures with special attention to the mucosal status. The degree to which the clinical staging was able to predict and correlate with radiologic staging and predict the degree of sinus

With the increasing popularity of sinus surgeries and the prolific advances in imaging technology, there is a major inclination towards the in-depth study of the anatomy of paranasal sinuses and the osteomeatal complex. Anatomical variations like deviation of nasal septum, paradoxical middle turbinate, double middle turbinate, and concha bullosa are seen in routine clinical examinations, but variations like Haller cells and Onodi cells require explicit radiological support.

Knowledge of these variations is very important for radiologists as well as endoscopic surgeons for preoperative evaluation to avoid damage to adjacent vital structures.

<p class="abstract"><strong>Background:</strong> Rhinosinusitis is one of the commonest sinonasal condition with chronic Rhinosinusitis affecting 10% of population worldwide. Although the diagnosis of chronic rhinosinusitis is clinical, the final diagnosis should be confirmed by objective measures like radiography and nasal endoscopy. Though anatomical variations in sinonasal region are rare, they have significant impact in the causation of sinonasal diseases and pose difficulties during surgery.</p><p class="abstract"><strong>Methods:</strong> This wa

Aim: Computed tomography (CT) provides an accurate assessment of sinonasal anatomy and osseocartilaginous pathologies in patients complaining of sinonasal symptoms. Although it is not a routine practice, CT is frequently used in preoperative screening of patients planned for septoplasty and septorhinoplasty. In this study, anatomical variations and ethmoid lateral lamella depths in preoperative CT images of septoplasty and septorhinoplasty operations performed in our clinic were analyzed retrospectively and discussed with current literature. Material and Method: Septorhinoplasty and sept

It depicts the anatomical variations in much simpler way and acts as a roadmap for endoscopic sinus surgery. In this study the maximum of participants were in the age group of 41- 50 years (32 %). The mean age of the study participants was observed to be 43.8 ± 15.6 years. HRCT PNS results shows nasal septum was found to be the most common anatomical variant (DNS- 94%).

The anatomical variations of sinonasal cavity are well documented in literature [1-3]. The sinonasal cavity is usually partially or fully imaged in cone beam CT (CBCT) exams taken for the teeth and jaws. So, oral and maxillofacial radiologists need to be familiar with the regional anatomy of the sinonasal complex (Figure 1). However, some anatomical variations can predispose to sinus disease or complicate sinus surgery. Therefore, solid understanding of the imaging anatomy of the sinonasal cavity is of paramount importance in order to eliminate or minimize surgical complications [4, 5]. CBCT s
