Extracraneal meningiomas represent 2% of all meningiomas and can appear in different locations including paranasales sinuses. There are no statistics regarding ectopic malignant meningiomas, but they are considered extremely rare. Due to this, there is no management protocol. We present a patient with a malignant meningioma of the etmoidal sinus, his treatment and the evolution over a five year period.
We have not found in the literature an explanation for the intermittent and transient decreased lesser hearing sensation in patients with dysesthesia of the external auditory canal (EAC). In this paper we offer a possible explanation for it. Our hypothesis is that the stimulation of the sensory fibers of the trigeminal and facial nerves in the EAC is able to increase the stiffness of the ossicular chain by means of a reflex stimulation of malleus and stapes muscles. This intermittent and transient increase of the ossicular stiffness could explain the intermittent and transient decrease of hearing sensation in these patients.
Since 1948, contact between two nasal structures has been accepted as a source of facial pain and numerous medical and surgical techniques have been used to alleviate it. We report a series of 15 patients with unilateral headache and contact between two nasal structures. All patients were tested with topical anesthetic to confirm the diagnosis. Diverse surgical techniques were used depending on the structures involved. In every case, surgery resolved or alleviated headaches.

We have noticed that macrolides can improve the main symptoms of many patients with chronic pharyngitis. We feel that the efficacy of macrolides for chronic pharyngitis can be due to the anti-inflammatory effect of this group of antibiotics. However, we think that at present the use of macrolides is not the therapy of choice for chronic pharyngitis.
