We have read with great pleasure the article written by Jiaqiang Sun and Jingwu Sun on the problem of intracranial complications (IC) of chronic otitis media (COM)... The middle ear colonization by anaerobic flora, Staphylococcus aureus and Pseudomonas aeruginosa is the cause of recurrent exacerbations of COM and as a consequence IC... Diagnostic tools such as CT or MRI and urgent surgical intervention allowed to treat all patients without neurological deficiencies... In the case of significant bone destruction, we used open technique in all cases... Based on the authors’ article and our experience and observations, we can assume that the etiological factors responsible for IC are biofilms produced by bacteria... Presence of a biofilm in the ear can contribute to COM exacerbation and as a result, bone destruction and IC... Failure to improve the condition of patients after antibiotic treatment suggests that we have encountered with “resistant” biofilms... At the present time it is difficult to avoid IC development... The thorough ear toilet, irrigation and applying drugs destroying the structure of the biofilms may be an important way to avoid IC... The latest assumption requires forward studies, because we do not have at our disposal the effective drugs destroying biofilms (Fig.  1).

Mentions: Exacerbation of the middle ear infection may be the indication for the use of an antibiotic which may mask, delay or suppress the symptoms of IC, allowing the diagnosis only when neurological symptoms are visible. Antibiotic therapy without ear drainage may also contribute to development of IC. Mechanical removal of biofilms may allow to improve treatment efficacy in COM. The six patients with chronic otitis media with cholesteatoma and IC were treated in our department between 2006 and 2012. Pseudomonas aeruginosa and Staphylococcus aureus were the most common isolated bacteria. Diagnostic tools such as CT or MRI and urgent surgical intervention allowed to treat all patients without neurological deficiencies. In the case of significant bone destruction, we used open technique in all cases. Based on the authors’ article and our experience and observations, we can assume that the etiological factors responsible for IC are biofilms produced by bacteria. Presence of a biofilm in the ear can contribute to COM exacerbation and as a result, bone destruction and IC. Clinical picture of COM has slightly changed in comparison to those from previous decades. Symptoms are at present less obvious and severe. Failure to improve the condition of patients after antibiotic treatment suggests that we have encountered with “resistant” biofilms. At the present time it is difficult to avoid IC development. The thorough ear toilet, irrigation and applying drugs destroying the structure of the biofilms may be an important way to avoid IC. The latest assumption requires forward studies, because we do not have at our disposal the effective drugs destroying biofilms (Fig. 1).Fig. 1
