Study the Impact of the Mastoid and Middle Ear Volume on the Success of Type 1 Tympanoplasty in Pediatric Age, With Comparing Using Cartilage and Fascial Grafts Through This, Strength the Hypothesis of That Total Tympanometry Volume Correlates With Ventilated Mastoid Air Cells Volume on CT Scans

The goal of this observational study is to know the impact of the mastoid and middle ear volume on the success of type 1 tympanoplasty in pediatric age, with a closer view on the comparison of using cartilage and fascial grafts through this. The investigators also hoping to strength the hypothesis of that total tympanometry volume correlates with ventilated mastoid air cells on Computed Topography (CT) scans that allow us to predict a well-ventilated mastoid air cell system. This may help reduce the need for pre-operative CT scans in uncomplicated cases with tympanic membrane perforations. The main question it aims to answer is: Does Mastoid ventilation affect the success of tympanoplasty (Type 1) in pediatric age group? and which graft is better and if the tympanometry volume (non invasive investigation) correlate with the degree of the mastoid pneumatization degree and volume (based on CT scan and 3D volumetric measuring). Participants already taking intervention a as part of their regular surgical treatment of chronic suppurative otitis media with perforation in the form of Type 1 tympanoplasty (Myringoplasty), informed consent was obtained from all the study participants guardians. Regular postoperative follow up of the success rate (structural success was evaluated 1 month postoperatively) and functional success were evaluated at 1.5 months and 3 months postoperatively.
