[The fronto-supra-ethmoidal approach. Its value in cerebrospinal rhinorrhea].

A supra-ethmoidal approach was used to treat cerebrospinal fluid rhinorrhea secondary to anterior fractures of the base of the skull. After an internal orbital incision, the anterior wall of the frontal sinus is removed and the posterior wall of this sinus trephined in the internal region of its horizontal portion in order to expose the meninges covering the roof of the first ethmoidal space. Dissection is continued within the space towards the anterior extremity of the apophysis of the crista galli against which the fibrous band issuing from the anterior ethmoidal opening is sectioned.

[Cholesteatomas of the fronto-orbital region].

Three cases of primary fronto-orbital cholesteatoma are reported and the relevant ORL and neurosurgical literature reviewed. Clinical diagnosis of this rare affection is not simple but is suggested by signs of infero-internal exophthalmus, an external orbital mass or exteriorized sinusitis after chronic headache. Two characteristic features are seen on radiology.
