Frontal sinus

[citation needed] Frontal sinuses are rarely symmetrical as the septum between them frequently deviates to either side of the midline.

[2] The development of these sinuses accounts for the suddenly increased mucus production at this age.

[citation needed] They are generally well developed, and functional between the sixth and eighth years, though they continue to grow slower until reaching their maximum size after puberty.

[4] Through its copious mucus production, the sinus is an essential part of the immune defense/air filtration carried out by the nose.

Nasal and sinal mucosae are ciliated and move mucus to the choanae and finally to the stomach.

The thick upper layers of nasal mucus trap bacteria and small particles in tissue abundantly provided with immune cells, antibodies, and antibacterial proteins.

[4] Endonasal approach into the frontal sinus in children with acute and chronic frontal sinusitis without the usage of surgical optics is not successful, because in this case the operation is performed almost blindly and technically difficult even in adults.

[6] Goals in management are to protect the intracranial structure, control any existing CSF leakage, prevent late complications, and aesthetically correct the deformity caused, if any.

If inhibiting the nasofrontal outflow tract, procedure is to undergo open reduction and internal fixation of the anterior table and osteoplastic flap with obliteration.

[citation needed] In the case of facial feminization surgery, modifications to the frontal sinus can be made to make the face more feminine, alongside softening the orbital rims.

Regardless of the material type, care should be taken to avoid having the implant sit directly underneath the incision as this leads to a higher rate of infection and removal.
