Success Rate of Intact Canal Wall Tympanoplasty in Safe Type of Chronic Suppurative Otitis Media’ Patients
Keywords:Chronic Suppurative Otitis Media, Safe Type, Intact Canal Wall Tympanoplasty, Intact Canal Wall Up Mastoidectomy
Background: Surgical therapy for chronic suppurative otitis media (CSOM) is by tympanoplasty with or
without mastoidectomy. The purpose of surgery is to eradicate the source of infection. Success indicators
of tympanoplasty are achieving dry ears without recurrent otorrhea, myringoplasty, and an increase in the
Objectives: is to know the success rate of intact canal wall tympanoplasty in safe type CSOM patients.
Methods: Retrospective descriptive was used in this study. All safe-type of CSOM patients undergoing intact
canal wall tympanoplasty surgery from January to December 2018 at Dr. Soetomo General Hospital were used
as the participant data.
Results : There were 32 participants, divided into a higher proportion of males than females (ratio 1.1:
1). The characteristics of the participants included; the most age group were 21-30 years (37.50%), origin
outside Surabaya (59.37%), and high school education level (62.50%). Most perforations were subtotal
(40.63%) and hearing loss was conduction (62.50%). Apparently, 56.25% were patent Eustachian tubes,
90.63% were sclerotic mastoid Schuller photographs, and 62.50% were granulation tympanic cavity findings.
Additionally, 78.13% were performed tympanoplasty type 1. The results of postoperative eradication showed
dry ears (84.38%) and successful of myringoplasty (71.88%). The mean increase in the hearing threshold for
AC, BC, and ABG after surgery was 15.98 dB, 4.57 dB, and 11.40 dB.
Conclusion: The results of eradication after intact canal wall tympanoplasty were mostly dry ears, successful
myringoplasty, and an increase in the mean hearing threshold of AC, BC, and ABG.
