Background: Knowledge of anatomy constitutes an integral part of the total management of patients with sinonasal diseases. The aim of this study was to obtain the prevalence of sinonasal anatomic variations in the Kashmiri population and to understand their importance and impact on the disease process, as well as their influence on surgical management and outcome. Materials and Methods: This study is a prospective review of retrospectively performed normal computed tomography (CT) scans of the nose and paranasal sinuses in the adult Kashmiri population at SMHS Hospital. The scans were reviewed by two independent observers. Results: The most common anatomic variation after excluding agger nasi cells were pneumatized Crista Galli, which was seen in 69% of the scans. However, the least common variation seen in this series was Pneumatized inferior turbinate, which was encountered in 1.1 % of the cases. Conclusion: A wide range of regional differences in the prevalence of each anatomic variation exists. Understanding the preoperative CT scan is substantially important because it is the roadmap for the sinus surgeon. Detection of anatomic variations is vital for surgical planning and the prevention of complications.

ABSTRACT Sinonasal inverted papilloma is a benign neoplasm of epithelial origin, which represents 0.5 to 4% of all sinonasal tumors. Despite the histological benign nature of this type of tumor, it has a high rate of recurrence after surgical resection and significant malignant potential. Sinonasal inverted papilloma is treated as a locally aggressive tumor. The aggressive surgical approaches, such as en bloc resection via external excision or extensive mucosal stripping of the ipsilateral sinuses are replaced by less invasive intranasal endoscopic approaches. This creates a need for a very accurate preoperative assessment of the location of the tumor on computed tomography (CT) scan and identifies the location of the primary changes. Determination of the primary location of inverted papilloma is especially important for a radical resection of the tumor, because the tumor recurs mostly in the same location as the primary lesion. The aim of this study was to determine the relationship between changes in the preoperative CT scan of the paranasal sinuses and the location of papilloma by histological examination of surgical material. In this study, we evaluated the changes in the preoperative CT scans in the form of focal hyperostosis and erosion of the walls of the paranasal sinuses. Examined groups consisted of 12 people diagnosed with inverted papilloma and 15 peoples diagnosed with preinverted papilloma. Focal hyperostosis occurred in 83% of cases of inverted papilloma. Their location corresponded to 90% of the primal attachment of the tumor. Among the preinverted papillomas, focal hyperostosis occurred in less than 7% of the cases and did not correspond to the location of papilloma inverted. The analysis of remodeling and erosion of bone walls of the sinuses showed their presence in 67% of cases of inverted papilloma and 40% of cases of preinverted papilloma. However, their overlap with the location of the tumor was 50% for the inverted papilloma and 33% for the preinverted papilloma. Erosion and sinus bone destruction do not coincide closely with the primary location of the papilloma, because it is more the result of bone compression by the growing mass than bone invasion. The sites of focal hyperostosis closely coincide with the place of origin of the inverted papilloma, but the pathophysiological mechanism of this phenomenon is not fully understood. The relationship between the sites of focal hyperostosis and the location of the primary tumor can be used when planning surgery for accurate resection. How to cite this article Salwa A.

AbstractObjective:To describe a newly observed frontal sinus anatomical variant, the fronto-septal rostrum.Methods:Consecutive sinus computed tomography scans performed during 2013 were reviewed. The fronto-septal rostrum was defined as a mucosa-lined air space formed in the attachment of the most upper bony nasal septum and the central floor of the frontal sinuses.Results:The study included 400 computed tomography scans from 189 women (47.3 per cent) and 211 men (52.8 per cent), with a mean age of 46.8 years. A fronto-septal rostrum was observed in 122 patients (30.5 per cent), with a mean length of 10.63 mm, width of 4.52 mm, height of 2.18 mm and volume of 63.52 mm3. There was no statistically significant difference related to gender (p = 0.343), and no association between the side of the fronto-septal rostrum and age (p = 0.811) or volume (p = 0.203).Conclusion:The newly described fronto-septal rostrum has possible clinical and surgical implications. It is suggested that this aerated space is used in specific surgical indications and its presence evaluated in cases of septal infection.

Objective: The agger nasi cell (ANC) is an easily identifiable landmark when approaching the frontal sinus. The success of endoscopic frontal sinus surgery may be influenced by the width of the frontal recess (FR). The aim of this study is to examine the relationship between the FR width and the ANC size in Japanese patients. In addition, the effect of various frontal recess cells (FRCs) on the development of frontal sinusitis has been examined. Materials and methods: Multiplanar computed tomography (CT) scans of the nasal cavities and paranasal sinuses in 95 patients (190 sides) before endoscopic sinus surgery were reviewed. The presence of FRCs, the thickness of the frontal beak (FB), the ANC size, and the anterior-to-posterior (A-P) length of the frontal isthmus (FI) and FR were evaluated in patients with and without frontal sinusitis. Results: The prevalence of the ANC, frontal cell types 1, 2, 3, and 4, frontal bullar cell (FBC), suprabullar cell, supraorbital ethmoid cell, and interfrontal sinus septal cell was 85.3%, 11.6%, 0%, 7.9%, 0%, 25.3%, 45.8%, 16.8%, and 15.3%, respectively. The ANC volume showed a significant positive correlation with the A-P length of the FI and FR. The incidence of frontal sinusitis in the patients with FBCs was significantly higher than that without FBCs. Conclusion: A large ANC offers a greater potential to facilitating the approach to the frontal sinus because of the extensiveness of the FR in Japanese patients. The presence of FBCs may be related to a higher incidence of frontal sinusitis.

Objective: Diagnosis of a distal end radius fracture relies on various imaging studies. However, the relative usefulness of these studies is still a matter of some controversy. The aim of this study was to compare the intra-observer and inter-observer reliability of plain radiographs, standard computed tomography (CT) scans and mobile CT scans in the assessment of distal radius fractures as categorized by the Fernandez classification method. The secondary objective was to compare the dosages of radiation between the different imaging modalities. Material and Methods: Sixteen fresh cadaveric wrist bones were used in this experimental study. The desired fractures were created in the bones to mimic Fernandez types I-V fractures and plain radiographs were taken in 4 views. Standard CT and mobile CT scans were also taken with the fractured bones in the same four positions. Interobserver reliability was assessed using Kappa statistics to determine the diagnostic consistency among the nine observers. Inter-observer agreement was assessed based on the Fernandez classification system diagnoses. Results: Overall, the inter-observer agreement was substantial for the Fernandez classifications (Kappa range 0.636 0.727) in all types of imaging. For intra-observer agreement, the analysis found higher agreement for both standard CT scans and mobile CT scans. The standard CT images imparted a higher average dose of radiation than both the mobile CT scans and the plain radiographs.Conclusion: The mobile CT scan can provide an alternative imaging method for precise diagnosis of distal end radius fractures, with the additional benefits of mobility and lower radiation exposure.

Cerebrospinal Fluid Leaks

Object An anterior clinoidectomy can provide enormous benefits, facilitating the management of paraclinoid and upper basilar artery lesions, but it also carries the potential risk of cerebrospinal fluid leaks. The aim of this study was to assess the variation in the pneumatization of the anterior clinoid process (ACP) in an attempt to reduce the complications associated with an anterior clinoidectomy. Methods The authors analyzed the anatomical variations in the pneumatization of the ACP and optical strut (OS) in 600 sides of 300 consecutive patients by using multidetector-row computed tomography (CT). Computed tomography scans with a 0.5-mm thickness were obtained, and coronal and sagittal reconstructions of the images were displayed in all cases. Pneumatization of the ACP was found in 9.2% of all sides. The origin of pneumatization was the sphenoid sinus in 81.8% of all the sides, the ethmoid sinus in 10.9%, and both of these sinuses in 7.3%. Pneumatized patterns were divided into three groups according to the route: 74.5% were Type I, in which pneumatization occurred via the OS; 14.5% were Type II, pneumatization via the anterior root (AR); and 10.9% were Type III, pneumatization via both the OS and the AR. The origin of pneumatization and the pneumatization pattern showed statistical dependence (p < 0.001). Pneumatization of the OS beyond its narrowest point was found in 6.8% of all sides. Conclusions An awareness of the different variations in pneumatization can prevent destruction of the mucous membrane and facilitate orientation during reconstruction with cranialization. During an anterior clinoidectomy, preoperative CT assessments are necessary to evaluate pneumatization of the ACP.

AbstractSinonasal malignant melanoma is rare and usually occurs in the nasal cavity. Presentation is often varied and occurs late in the natural history of the disease, resulting in a poor prognosis. A case is reported of a patient with malignant melanoma arising from the frontal sinus who presented with a forehead swelling and progressive confusion. A review of the literature on malignant melanoma in the nasal cavity and paranasal sinuses regarding its presentation, site of origin and principles of management is discussed.
