Abstract Background As the hard palate is a central structure of skull, and its close relationship with nasal cavity, oral maxillary sinuses, it would be interest to study if there between this bone other structures stomatognathic system. Thus, aimed assess dimensions associate them sex, skeletal breathing patterns. Also, investigate these volumes upper airways sinuses. Methods Two hundred nine...

In this chapter, we examine the chronic inflammatory diseases of the nasal cavity and paranasal sinuses. First, we examine the basic characteristics of the various chronic inflammatory diseases of the nasal cavity and paranasal sinuses and chronic inflammatory diseases of the oral cavity. Further, we discuss the etiopathogenesis, diagnosis, differential diagnosis, and treatment options for the ...

Inverted papilloma (IP) is a benign tumor of the nasal cavity and paranasal sinuses that is unilateral in most cases. Bilateral IP, involving both sides of the nasal cavity and sinuses, is extremely rare. This paper describes a large IP that filled in both sides of the nasal cavity and sinuses, mimicking association with malignancy. The tumor was successfully treated by bilateral endoscopic med...

UNLABELLED Inflammatory pseudotumors may be defined as lesions that clinically and radiologically simulate neoplasms. These tumor are not a single clinical-pathological entity, but rather a generic term applied to any nonspecific, chronic, inflammatory expanding lesion. There are few reports of inflammatory pseudotumors in the nasal cavity and paranasal sinuses. CASE REPORT We report three ca...

Juvenile Paget's disease (JPD) is a rare skeletal disorder that's characterized by bone demineralization and elevated levels of serum alkaline phosphatase. JPD involves the paranasal sinuses in extremely rare cases. We report here on a 25-month-old Asian male who was diagnosed of JPD associated with aplasia of the paranasal sinuses, but not the ethmoid sinuses. The patient was successfully trea...

Oroantral fistula (OAF) is an abnormal connection between the oral cavity and maxillary sinuses. This pathology develops when oroantral communicant fails to close spontaneously; thus, it remains patent epithelialized. If not treated immediately, this condition might be passage for bacteria enter sinuses, causing infection, sinusitis, or delayed healing. Consideration of OAF therapy should consi...

Aneurysm of the sinus of Valsalva is not an uncommon disorder. Its incidence has been estimated at 3 5 per cent of surgical congenital heart diseases, and the condition can be diagnosed with a fair degree of certainty on clinical and haemodynamic grounds and is amenable to surgery in a fair number of cases (Taguchi et al., I969). The majority of the cases show involvement of one, and some cases...

Dural arteriovenous fistulae of the transverse and sigmoid sinuses are highly variable in symptomatology and prognosis. However, we have identified a subgroup of patients who have a high risk of hemorrhage and dementia due to severe venous overload caused by high arterial flow into the fistulae and by occlusive changes of the transverse and sigmoid sinuses. Three representative cases selected f...

Introduction: Mucoceles of the paranasal sinuses are relatively rare. A very busy otolaryngology department does not have more than a few cases each year. Bilateral, multiple, and multiloculated cases are extremely unusual. Case Presentation: We report a 74-year-old man with two separate mucoceles in left ethmoid and frontal sinuses with pansinusitis. After marsupialization of mucoceles and fun...
