J Laryngol Otol Suppl. The frontal sinuses undergo most of their development after birth and are considered as extension of an anterior ethmoid cell. They are sited posterior to the superciliary arches between the tables of the frontal bone. They extend upwards and backwards next to the medial part of the roof of the orbit. Each frontal sinus may be of a different size [ 1 Sklavounos G.

Click here to see the Library ] [ 4 McMinn R. New York, Churchill Livingstone, Click here to see the Library ]. Anatomical variations of their size and site may reflect on the pathology of the anatomically related areas by direct extensions, or through the extensive plexuses of the related veins and lymphatic vessels.

Three interesting malformations of the frontal sinuses were found in a series of routine educational cadaver dissections. The cadavers were dissected one month after their withdrawal from the formol basin.
In the great majority of the studied cadavers the structure of the frontal sinuses revealed only the usually described anatomical characteristics.
In the three described cases however, the malformations found were quite interesting and are presented. Upon opening the 0. Medially the frontal mucosa extended up to the olfactory sulcus and laterally it reached the boundary of the orbital part of the frontal bone and the lateral wall of the orbit. This projection of the mucosa, covering half of the orbital roof, was cushion like having a 4 mm thickness at its center and 2 mm at its border.
Under this projection of the mucosa of the frontal sinus there was a second bone plate, 0. Posteriorly it covered one third of the distance between the optic foramen and the frontal bone, medially it reached the olfactory sulcus, and laterally the boundary of the orbital part of the frontal bone and the lateral wall of the orbit.
This projection of the mucosa of the frontal sinus covered about one third of the roof of the orbit. At its center it was approximately 3 mm thick and at its border 1.
Under this mucosal projection there was a thin bone plate 0. There was a complete aplasia of the frontal sinuses. Upon sectioning serially the frontal bone a brownish site was revealed within the bone in the area were the sinuses should be sited fig. Frontal sinus anatomy may play an important role in the causes of sinusitis and possibly in the causes of orbital cellulitis. Clairmont and Per-Lee have expressed the belief that the thin bone separating the frontal sinus from the anterior cranial fossa and orbit, and the interrelated venous drainage system in these areas, form the anatomic basis for the serious orbital and intracranial complications of acute frontal sinusitis [ 5 Clairmont A.
A, Per-Lee J. Complications of acute frontal sinusitis. Physician,11 5 Evaluation of orbital cellulitis and results of treatment. Laryngoscope, 92 Orbital cellulitis. Br J Ophthalmol. The clinical significance of the inflammations of the frontal and paranasal cavities in general and their correlation with the orbit is well known. Cases of acute orbital inflammation with preseptal cellulitis, subperiosteal abscess or orbital cellulitis in the presence of nasosinusitis are often found in the bibliography.
Moloney and colleagues announced 34 such cases [ 8 Moloney J. The acute orbit: Preseptal periorbital cellulitis, subperiosteal abscess and orbital cellulitis due to sinusitis. Bertran and Martinez-Vidal summarized 40 cases of orbital complications of sinusitis: 34 cellulitis, 4 exophthalmos and 2 neuritis of the optic nerve [ 9 Bertran J. Orbital complications of sinusitis. Study of 40 cases. An Otorrinolaringol Ibero Am.
Pender described even a Pott's puffy tumor as a complication of frontal sinusitis [ 10 Pender E. Pott's puffy tumor: a complication of frontal sinusitis. Care, 6 4 Magnano and colleagues described 8 patients with orbital complications of complicated frontal and ethmoid-maxillary sinusitis [ 11 Magnano M.
