Introduction:
Nasal polyposis is a chronic inflammatory disorder of the mucosa characterized by the development of benign inflammatory growths within the nasal and sinus cavities. It is usually associated with chronic rhinosinusitis (CRS) but is also observed in aspirin-exacerbated respiratory disease, vasculitis, and cystic fibrosis. Its pathogenesis is believed to arise from a complex interaction of genetic predisposition, immune dysregulation, and environmental factors. It can present with nasal obstruction, anosmia, rhinorrhea and facial pain, thus reducing the quality of life of affected patients. Diagnosis is based on careful history and physical exam, including anterior rhinoscopy or endoscopic examination. Imaging studies help assess the disease's extent and aid in surgical planning. Treatment strategies may range from medical management with corticosteroids and targeted biologics to surgical intervention in severe or refractory disease cases. The role of surgery is to remove the anatomic obstruction in order to enhance the effect of topical intranasal steroids on the affected sinonasal mucosa postoperatively.

Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
