Variables Influencing the Extrusion Rate of Ventilation Tubes

Mahmoud Ahmed Nagy Mohamed, Ayman. A.El-Shehally and Ali khalaf Mahrous

Abstract

Background: Otitis media with effusion (OME) is a frequent pediatric disorder. it is the most common cause of conductive hearing loss in children. It results in variable degrees of hearing loss which can affect the auditory system development during this early and important period of life . Aim and objectives: The study aimed to determine the factors which might affect the extrusion rate of ventilation tubes. Subjects and methods: This is a prospective study to determine the factors which might affect the extrusion rate of ventilation tubes. The study was conducted on 88 patients who were diagnosed with persistent bilateral otitis media with effusion.They were collected from ENT clinics of AL-Hussain university hospital and Mansheyat EL-bakry general hospital .They underwent myringotomy with ventilation tubes insertion with or without adenoidectomy, during the period from December 2019 to April 2022. Results:there was no statistically significant difference between age ,gender, recurrent post -operative upper respiratory tract infection , adenoidectomy needed or not, presence of cleft palate or not, grade of surgeon and the time of tube extrusion among study group, there was a statistically significant difference between site of tube insertion and the time of tube extrusion among study group p value=0.009 , postero -inferior insertion has more rapid tube extrusion than Antero- inferior and antero- superior insertion. there was a statistically significant difference between type of grommet and the time of tube extrusion among study group p value = 0.0001 as regards type of grommet as shepard has more rapid tube extrusion than Armstrong's grommets with statistical significant difference ,Conclusion: the current study showed factors that shorten ventilation tube extrusion time. there was a statistically significant difference between site of tube insertion,type of grommet tube and the time of tube extrusion. there was no statistically significant difference between age ,gender, recurrent post -operative upper respiratory tract infection , adenoidectomy needed or not, presence of cleft palate or not, grade of surgeon and the time of tube extrusion
