According to medical literature, the frontal recess' intricate physical structure resembles an inverted funnel. The anatomical structure is not distant from the frontal ostium. Surgery requires a good understanding of the frontal recess …

The frontal recess region has a complex anatomy and HRCT scans of the paranasal sinuses (PNS) are the gold standard in evaluating it. Classification systems have been established to identify the frontal recess cells. The objectives of this study …

Isolated frontal sinus disease is a rare and highly morbid condition. Although chronic frontal sinusitis has been described in literature, clinically it is quite uncommon in the absence of paranasal sinusitis and rhinitis. Here we examine a case …

The frontal sinus is frequently described as the most problematic sinus to access surgically due to its challenging and variable anatomy together with its proximity to important structures such as the cribriform plate, orbit, and anterior ethmoid …

Fungal sinusitis is a form of sinusitis that can be either invasive or noninvasive, with the development of a fungus ball being the most common non-invasive presentation of this condition and with the unilateral maxillary sinus being the most …

Endoscopic sinus surgery (ESS) is the gold standard for treatment of chronic rhinosinusitis (CRS) that is resistant to medical treatment. A complete understanding of the anatomy of the paranasal sinuses is necessary to achieve successful surgery.

Odontogenic sinusitis (OS) is a common condition that accounts for 10–40% of all cases of maxillary sinusitis (MS) [ 1 – 4 ] and up to 75% of cases of unilateral MS [ 5 ]. OS may result from violation to the maxillary sinus mucosal lining …

The osteomeatal complex plays an important role in the development of Chronic rhinosinusitis. The ethmoidal infundibulum is bordered medially by the uncinate process, and the anatomic relationship between the ethmoidal infundibulum and the frontal …

To modify the endoscopic frontal sinus surgery and improve the therapeutic effect of recurrent chronic frontal sinusitis (RCFS). Eighty-five patients with RCFS were divided into two groups. Endoscopic frontal sinus surgery through an approach of …

Even though being a rare condition in the era of antibiotic treatment, complications of acute frontal sinusitis still pose a potentially life-threatening problem. We present a clinical case series using a combined surgical approach. Within a 7 …

Endoscopic sinus surgery has brought a change in the concept of treatment of sinus disease. Frontal sinusitis, however, still gives rise to intra and extracranial complication often musked by antibiotic intake. Where endoscopic surgery may fail to …

Intracranial extradural hematoma is usually traumatic. Rarely, it can occur spontaneously associated with coagulative disorders (spontaneous or iatrogenic), dural vascular malformation, cranio-facial tumors and infections. In these cases …

The anatomy of the nasal cavity and the paranasal sinuses is complex. After widespread use of endoscopes and computed tomography, many variations have been described. Secondary and accessory middle turbinates (AMTs) can mimic the real middle …

The frontal recess is a tight and often challenging space to navigate surgically, which can consequently affect the patency of the frontal sinus ostium after endoscopic sinus surgery. The anterior location of the frontal sinus often requires the …

Introduction: International frontal sinus anatomy classification (IFAC) was introduced in 2016 to standardize the nomenclature of the cells in the frontal recess region, facilitate better communication between surgeons and precision in surgical …

Frontal sinusitis is the inflammation of the frontal sinuses, associated with the presence of microorganisms or irritants causing overproduction of mucus with or without blockage of sinus drainage [ 1 , 2 ]. Majority patients with frontal sinusitis …
