Abstract:
Objective To study the correlation between the characteristics of tympanic membrane perforation and hearing loss in chronic suppurative otitis media.Methods Ear fibreoptic endoscopic images and complete audio-logical data of 80 patients(104 ears)diagnosed with chronic suppurative otitis media and treated with tympanoplasty type Ⅰ surgery at the Department of Otorhinolaryngology-Head and Neck Surgery of the Second Hospital of Lanzhou University from July 2022 to July 2023 were reviewed.The area of tympanic membrane perforation was measured u-sing ImageJ software.Qualitative variables were professionally assessed by a senior practitioner in otology,inclu-ding whether the perforation involved the quadrant,whether the edge of the perforation was calcified,and whether the extent of the perforation involved the malleus.Results There was a significant positive correlation between the area of tympanic membrane perforation and the mean air-bone conductance difference in patients with tympanic mem-brane perforation due to chronic suppurative otitis media(R2=0.141,P<0.001).The patients with perforation in-volving the malleus handle had a greater air-bone conductance difference than those without malleus handle involve-ment(P<0.05).The effect of calcification at the edge of the tympanic membrane perforation and the location of the perforation on hearing loss was minimal and almost negligible.Conclusion Conductive hearing loss due to tympanic membrane perforation is related to the size of the perforation and whether or not the perforation involves the malleus handle,and the patients with larger perforation as well as those with perforations involving the handle of malleus tend to exhibit worse conductive hearing loss.
