Introduction

In preschoolers, middle ear disorders are fairly prevalent. General practitioners, as well as ear, nose, and throat (ENT) and paediatric specialists, have a difficult time diagnosing middle ear illness. The GP must rely on otoscopy in addition to a medical history and a general objective examination, which is commonly performed in a narrow and tilted ear canal with hair and earwax. Furthermore, the youngster may have a low level of examination compliance. The two most frequent middle ear illnesses in children are acute otitis media and otitis media with effusion. When a middle ear effusion is present, as evidenced by pneumatic otoscopy, tympanometry, air fluid level, or a bulging tympanic membrane, as well as signs of acute inflammation in the middle ear with opacity is diagnosed. Symptoms of otalgia, irritability or fever, as well as a white or erythematous tympanic membrane or purulent discharge from the middle ear. When a middle ear effusion is evident, but there is no acute inflammation or symptoms of acute sickness, OME is diagnosed. When a child gets a cold, OME is common, and it might progress to AOM. A period of AOM is frequently followed by a period of MEE. As a result, we frequently observe middle ears where distinguishing between AOM and OME is difficult. Because the treatments for AOM and OME are different, it's crucial to understand the differences. Antibiotics are most commonly used in preschool children for AOM, while antibiotics have little effect on OME [1].

Description

The US Clinical Practice Guideline on OME strongly advised doctors to use pneumatic otoscopy as the primary diagnostic approach, with tympanometry as an alternative for confirmation and documentation of effusion duration. When compared to traditional otoscopy, pneumatic otoscopy improves diagnosis by 15% to 26%, although it is rarely used by general practitioners. In a survey in Denmark, just 11% of general practitioners employed pneumatic otoscopy, despite having access to the technology. Tympanometry is the electroacoustic measurement of the tympanic membrane's impedance. When compared to the results of myringotomy without overpressure ventilation, tympanometry shows a high sensitivity and specificity in identifying middle ear effusion in young children in a vaccination developed in Finland The negative predictive value of tympanogram was 0.94/ A type B tympanogram had roughly the same positive predictive value in several investigations. Despite these high numbers, tympanometry's use in general practise has only gradually increased. Despite the fact that handheld equipment has been on the market fo found that tympanometry was rarely use in general practise in Denmark in 1998.

Since, GPs in Denmark have been given a special fee for performing tympanometry when clinically justified, in order to improve the quality of diagnosis in children with ear complaints. We believe that the usage of tympanometry is lopsided, with some GPs never using it and others using it frequently. Because they oversee funding for GPs' activities, including tympanometry, the Danish National Health Service Register covers all GP clinics in all five regions of Denmark in the Region of Southern Denmark and the Region Zealand each had GPs in clinics on their lists. All GPs and practise nurses in two Danish regions were invited to attend one of four identical 6 hour tympanometry and otitis media courses. Updates on middle ear disease, data on a prospective cohort research on middle ear disorders, theoretical and practical information on tympanometry, technical presentations of two different tympanometry, and practising tympanometry were all part of the agenda. All participants received a brief questionnaire. The seminar offered an introduction to taking part in a prospective cohort study in general practise on children with middle ear issues. The Statistical Package for the Social Sciences and Statistics with Confidence 2nd edition were used to analyse the data. When 95 percent confidence intervals are applicable, they will be reported. The level of significance utilised was 5% [2-5].

Conclusion

The studies focus on comparing difficulties reported before and after the course. Although our study, which used a self-reported postal questionnaire sent to GPs and their participating nurses, cannot be directly compared to these three prospective studies, some of the same issues that our participants faced were documented in previous studies. Our survey also validated significant information from the tympanometer while treating otitis media in youngsters. The individuals with no prior experience in our survey had the same low incidence of difficulties as the more experienced participants following the training, which was an interesting finding. They appear to have undergone the necessary tympanometry training. Despite the fact that tympanometry has been used in general practise for more than 15 years, its use is still lopsided, with some GPs not using it.
