Demographic characteristics of patients were such that tympanic membrane perforation
was commonly found on right side 22 (61.1%), predominantly involving anterio-inferior site 19 (52.8%) and medium sized perforation outnumbered N.22 (61.1%) (Table-I).
There is no relation of duration of symptoms with either size or site of tympanic membrane perforation
in chronic otitis media.
(2.) Showed isolated tympanic membrane perforation
and normal middle ear structure in their first otoendoscopic examination;
The experimental method employed in our study required to induce tympanic membrane perforation
. In a study using the similar method by Ueda et al.
Also, we have to note that our study did not include total tympanic membrane perforation
During the chart review, patient demographics, date of blast, date of ear examination and of pure tone audiometry (PTA), presence or absence of symptoms, type, duration and intensity of symptoms, otological findings for presence of tympanic membrane perforation
, presence of blood/clot or discharge in external auditory canal and pure tone audiometry findings were collected.
Three (7.5%) had subtotal, 12 (30%) patients had large size, 24 (60%) medium size and one (2.5%) had pin hole size tympanic membrane perforation
. Out of 40 cases, 22 (55%) tympanoplasties were performed on right ear and 18 (45%) on left ear.
Tympanic membrane perforation
: size, site and hearing evaluation.
A recent report by a group of military physicians showed a high incidence of tympanic membrane perforation
(35.2%) in blast-injury survivors .
Endoscopic fat grafting of small and residual tympanic membrane perforations
- a clinical study.
It has been shown that in individuals with tympanic membrane perforation
, various substances can affect the cochlea through the round window and cause ototoxicity by passing from the middle ear through the external auditory canal [3, 4].The inner ears of individuals with tympanic membrane perforation
are exposed to disinfectants used in pool water while plunging into pools.
Objective: To determine incidence and characteristics of traumatic Tympanic Membrane perforation
in a tertiary care hospital.
