“…The mean age of our study subjects with CSOM was 26.8 years which is almost in par with the study done by Shiromany et al and Tadke et al and further they had quoted that the incidence of CSOM was more prevalent in 2 nd decade. 14,15 In our study we found a female predominance in the incidence of CSOM and a similar type of results was also seen in the study done by Tadke et al and Holmquist et al, whereas few other studies had found a male preponderance and so we can't generalize a particular gender as more risk for developing CSOM. [15][16][17][18][19] Foreign materials introduced into the middle ear are evacuated through the ET to the nasopharynx within minutes at a speed that corresponds with the known capability of cilia.…”

Background: Pre-operative test of eustachian tube (ET) function is important for achieving a satisfactory result of tympanoplasty for CSOM patients. The saccharin test and methylene blue test seems to provide adequate information of the mucociliary function and patency of the ET. The aim was to study the ventilatory and mucociliary function of Eustachian tube in patients with chronic suppurative otitis media planned for tympanoplasty surgery and to assess the success rate of tympanoplasty in relation to the Eustachian tube functionMethods: A prospective longitudinal study was conducted for a period of one year. Patients aged more than 15 years with features of chronic suppurative otitis media of either tubotympanic type or atticoantral type were included in the study. The total number of study subjects included in our study was 82 patients with CSOM. The ventilatory and the mucociliary functions of the auditory tube were assessed preoperatively using saccharin test and methylene blue test. All patients with CSOM underwent tympanoplasty surgery and the outcome of the surgery was assessed. Results: The overall success rate of tympanoplasty surgery was 76.8%. It was observed in our study that the success rate of tympanoplasty was higher among patients with normal eustachian tube function.Conclusions: Preoperative evaluation of eustachian tube function is mandatory for all the patients planned for tympanoplasty. Preoperative and intraoperative corrective measures should be taken in patients with partial and absent tubal function to improve the success rate of tympanoplasty surgeries.

Introduction: Eustachian tube (ET) also known as pharyngotympanic tube connects nasopharynx with the middle ear. Evaluation of ET anatomy is aimed in patients with chronic otitis media. Materials and Methods: In a study of 53 patients, HRCT Temporal bone was done on 128 dual source simens somatom definition flash machine on 5mm cut section and tympanoplasty was carried out. Results: ET angle is one of the important factors for middle ear aeration. Outcome of tympanoplasty at 12th week was 88.7%. In the patients with vertical Eustachian Tube (i.e., more Eustachian Tube angle with the horizontal plane), better graft uptake in tympanoplasty was observed which was statistically significant. However, graft uptake did not correlate with the length of the Eustachian tube. Conclusion: It was concluded that on measuring ET length on HRCT, majority of the patients had bony length of 10-12 mm, cartilaginous length of 15-19 mm and total ET length of 28-32 mm. Majority of the patients had ET angle of 21-30 degrees with the hard palate.
