Epidemiologic Profile of Patients with Chronic Ear in Otology Service Medical of Otorrinolaringolgy Residency at Feira Santana / BA

Introduction: Chronic otitis media (COM) is a process of inflammatory nature of middle ear and mastoid with or without a tympanic membrane perforation and otorrhea, potentially leading to a conductive or mixed hearing loss. It is estimated that over 20 million people worldwide suffer from COM. The COM can be divided into two groups: simple and suppurative. The latter group is subdivided into noncholesteatomatous (COMNC) and cholesteatomatous (CCOM). The "radical mastoidectomy" surgery is indicated for these cases and constitutes in cleaning and clearing of the mastoid and posterior and superior bony wall of the external auditory canal.

Methodology: Study was conducted prospectively with patients COMNC, CCOM and underwent surgery in a medical residency in otolaryngology in Feira de Santana-BA during the period between 2008 and 2014. We monitored the patients for 8 months postoperatively.

Results: The following surgeries were proposed: radical mastoidectomy (MR), tympanomastoidectomy (TM), and tympanoplasty (TP), 304 surgeries being performed. Among these, 152 were TM, TP 64, and 88 MR. There was a predominance of females in all types of surgeries. The improvement in hearing was assessed subjectively with significant hearing improvement.

Discussion: The data obtained in this study confirm the benefit of surgery in the treatment of chronic otitis media.

Conclusion: Other studies correlating both subjective and objective improvement of hearing in the evaluation of patients with chronic otitis media undergoing surgery are needed.
