What is maxillary sinus Pneumatization?
Sinus pneumatization is a continuous physiological process that causes the paranasal sinuses to increase in volume [5]. Sinuses give resonance to voice, contribute to the shape of the face, and provide some degree of warmth and humidification to inspired air [6].
What causes maxillary sinus Pneumatization?
of some factors that may influence maxillary sinuses pneumatization, such as heredity, nasal mucous membrane pneumatization, craniofacial configuration, bone density, sinus surgeries, growth hormones, air pressure within the cavity of the sinus and an age- related process.
What sinuses are Pneumatized at 4 years old?
The pneumatization rate of maxillary sinus reached 100% after 4 years old. The pneumatization rate of ethmoid sinus was 100% in this study. The pneumatization rate of sphenoid sinus was 0 within 1 year old, 49% within 4 years old and 100% after 7 years old.
When do maxillary sinuses Pneumatized?
And 45.7% (21/46) of maxillary sinuses showed pneumatization during the first month of life and 97.8% (45/46) were pneumatized at 7 – 12 months. The pneumatized sphenoid sinuses was first identified as early as 4 months. And 86% (43/50) were pneumatized from 1 to 2 years old.
What does Pneumatized mean in medical terms?
air-filled cavities
Medical Definition of pneumatized : having air-filled cavities.
What is the function of maxillary sinus?
The maxillary sinuses might simply serve to improve the respiratory function of the nose. A flow of inspiratory air does not occur. The maxillary sinuses are decisively involved in the production of nitrogen monoxide (NO) and thus in supporting the immune defense of the nasal cavity.
When do babies sinuses develop?
The paranasal sinuses develop and enlarge after birth; ethmoid and sphenoid sinuses may not be of significant size until age 3-7 years. The frontal sinuses are the last to develop and may not be of significant size until adolescence.
At what age do the frontal sinuses show air space?
The frontal sinus is radiographically detectable by age 7 and reaches complete development in adolescence. The sinus may be a single or paired structure, with one or several vertical septa.
Can a 3 year old have sinusitis?
Sinusitis is a common infection in children that results in inflammation of the sinuses. It’s possible, but rare, for babies to get sinus infections because their sinuses aren’t fully formed. Sinusitis can be caused by either a virus or bacteria. Some children get recurring sinus infections.

When does Pneumatization occur?
Secondary pneumatization into the frontal bone begins between the ages of 6 months to 2 years. The frontal sinus is radiographically detectable by age 7 and reaches complete development in adolescence. The sinus may be a single or paired structure, with one or several vertical septa.
What is Pneumatization?
Medical Definition of pneumatization : the presence or development of air-filled cavities in a bone pneumatization of the temporal bone.
When does the maxillary sinus begin to develop?
The maxillary sinus (MS) is the largest paranasal sinus and the first to develop. Development commences at 17 weeks in utero.
Who are the doctors who treat the maxillary sinus?
Objectives: The maxillary sinus is of paramount importance for otolaryngologists, rhinologists, oral and maxillofacial surgeons, head and neck and dental and maxillofacial radiologists. A comprehensive review article concerning the physiology, development and imaging anatomy was undertaken.
What is the origin of rhinogenic sinusitis?
Sinusitis of rhinogenic, rather than odontogenic origin, originates from nasal inflammation followed by anterior ethmoid disease and secondary obstruction of the ostiomeatal unit. The role of anatomical variants that predispose to this pattern of disease is discussed in detail with illustrative examples.
What is the mucosa of the maxillary sinus?
Normal mucosa in the MS is visualized as a thin, smooth peripheral soft tissue density or signal layer on the inner surface of the sinus walls. Histologically, from outer to inner, it consists of periosteum, highly vascularized lamina propria and a thin layer of a pseudostratified columnar ciliated epithelium.
