Sectional Imaging

The anterior skull base (ASB) is intimately associated with the unique soft tissue subtypes of the nasal cavity, paranasal sinuses, orbits, and intracranial compartment. Pathology involving the ASB is rare but the causes are manifold and can be broadly subdivided into those intrinsic to the skull base and processes extending from below or above. Sinonasal pathology is the most commonly encountered and poses significant management challenges that rely heavily on accurate interpretation of the radiological findings. We illustrate the normal anatomy of the ASB and present a cross-sectional imaging review of the pathological entities that may be encountered, focusing on the specific features that will impact on clinical and surgical management.

Sectional Imaging

Diagnostic imaging of the equine neck is undertaken for a wide variety of conditions. In many cases, radiography is the principal imaging modality, often complemented by ultrasound examination. Common conditions encountered include osteoarthritis, articular process joint osteochondral fragmentation, cervical vertebral malformation (‘wobbler’), fractures and numerous soft tissue lesions. The complex three-dimensional anatomy of the region limits interpretation of planar images and, in some cases, cross-sectional imaging (such as computed tomography) may be required. However, careful use of radiography and ultrasound can help clinicians to achieve a diagnosis in many cases, often from combining conventional and lesion-orientated projections with a thorough clinical examination.

The Stability

Chapter 49 discusses spinal fixation hardware. The spine is the primary structural support of the human body. Traumatic, neoplastic, infectious, or degenerative disruption of the 3 columns of the spine causing pain and instability are the primary indications for spine surgery. Implanted hardware is used to provide short-term stability while osseous fusion of bone graft develops. Radiographs are routinely used for pre- and postoperative evaluation. Spinal fusion is used to restore and maintain disc space height, to decompress the spinal canal and neural foramina, to maintain normal lordosis, and to increase the stability of involved segments. Cross-sectional imaging is important for identified hardware and soft tissue complications.

<p class="abstract"><strong>Background:</strong> Aplasia or agenesis of frontal sinuses is not uncommon in the literature. Previous studies have shown unilateral aplasia varying from 1-10% and bilateral agenesis of frontal sinus in 3-10% of patients. It is critical for the operating surgeon to be well aware of the normal anatomy and the variations while doing procedures like endoscopic sinus surgeries, cranialisation of frontal sinuses, frontal sinus trephination, and during anterior skull base procedures. The aim of this study is to demonstrate the incidence of anatomic variations of frontal sinus among Indian populations<span lang="EN-IN">. </span></p><p class="abstract"><strong>Methods:</strong> We did a cross sectional study on computed tomography (CT) scan of head, nose and paranasal sinuses in 730 patients above the age of 10 years. We excluded pregnant ladies, patients with prior sinus surgeries, sinonasal tumors, nasal polyposis, craniofacial trauma<span lang="EN-IN">.  </span></p><p class="abstract"><strong>Results:</strong> <span lang="EN-IN">We observed an incidence of 6.2% of unilateral aplasia of frontal sinus (2.2% in males and 4.0% in females, 3.7% right side and 2.5% left side) and 2.5% of bilateral frontal sinus aplasia (0.95% in males and 1.5% in females). </span></p><p class="abstract"><strong>Conclusions:</strong> Frequent occurrence of frontal sinus aplasia highlights the need to gain a thorough knowledge of the normal anatomy and its variations in order to navigate safely through the nose during basic endoscopic sinus or anterior skull base surgeries to avoid complications<span lang="EN-IN">.</span></p>
