Chronic otitis media, defined as persistent or recurrent inflammation of the middle ear mucosa, is a frequent entity in primary and secondary care. This disease causes otorrhea and hearing loss that significantly affect the quality of life of patients. In recent years, there have been new developments in its diagnosis, prevention and treatment. In this last aspect, pharmacological treatment, surgical techniques and hearing rehabilitation through implants have shown significant advances. On the other hand, chronic otitis media complications continue to occur in emergency services and have to be kept in mind because of their potential seriousness. The objective of this work is to offer the reader an update in chronic otitis media, so it may help improving the care of affected patients.

Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
