Tympanoplasties in San Vicente de Arauco Hospital: 3 years review

Abstract

Introduction: Tympanoplasty is the treatment of choice for chronic otitis media. In Chile, several studies have been carried out to evaluate the success of tympanoplasty. Here, we asse- sed the anatomical and functional outcomes, correlating the results with the demographics of our population. Aim: To carry out an epidemiological description of patients with a diagno­sis of chronic otitis media who underwent tympanoplasty at our hospital between 2017 and 2019. Material and Method: Retrospective, descriptive study. We reviewed clinical records of patients who underwent surgery between January 2017 and November 2019. This study has been approved by the ethics committee of Arauco health service. Results: 77 tympano- plasties were performed, of which 56 ears met the inclusion criteria. 71.43% were female. The age range is 8 to 64 years. 41% had chronic pathologies. 51.79% were left ear surgeries. 92.86% were type I tympanoplasty. An endoauricular approach was performed in 58.93%. A cartilage - perichondrium composite graft was used in 75% of the surgeries. A medial tech- nique was performed in 94.94%. Anatomical success was achieved in 85.71% of patients. An average gain over 10 dB was obtained in 60.71% of the patients. Conclusion: There were no significant differences regarding the surgical choices with the anatomical and auditory results.
