RESUMEN
Benign osteonecrosis (BON) of the external ear canal (EEC), also termed as focal or circumscribed necrotizing lesion, is an infrequent phenomenon with distinctive features and of an obscure origin. Five patients with BON of the EEC presented with aggressiveness and extension of varying degree including involvement of the middle ear. It seems that the disease might have a self limited course (two patients) though, at times, extensive measures including hyperbarric oxygen therapy (one patient) should be applied.

Arytenoid subluxation (AS), ie, malpositioning of the arytenoid cartilage with abnormal but existent contact between the joint surfaces, is an uncommon entity, and fewer than 70 cases have been reported, 26 of which were in a recently published series. Usually, AS is the result of upper airway instrumentation, and only a few cases were reported to occur with external trauma to the neck. Some predisposing factors and possible mechanisms have been suggested, but the reason for its occurrence remains obscure. Hoarseness and, to a lesser degree, dysphagia, odynophagia, cough, and sore throat may be indicative of AS. Diagnosis is established by the clinical course, laryngoscopy, and computed tomography. Electromyography and strobovideolaryngoscopy are additional diagnostic measures described. We report 7 cases of postintubation AS of long standing. Three of these patients had prior unilateral vocal cord paralysis, formerly undescribed as a possible contributing factor for AS. The pertinent literature is reviewed and treatment options are discussed.

Acute suppurative parotitis and parotid gland abscess are infrequently encountered among children. Fourteen children were diagnosed in the Sheba Medical Center as suffering from these infections and their clinical features are described. Discussion reveals neither significant differences nor predominating factors to differentiate between these two entities.
