Interrelation between anterior Nasal Packing and Middle Ear Pressure- an Observational Study
摘要
Middle ear pressure changes may arise from various conditions including eustachian tube malfunction and middle ear pathologies such as otitis media with effusion leading to chronic otitis media. Eustachian tube dysfunctions are nasal pathologies such as rhinosinusitis, nasal polyposis, etc. The study’s objective is to evaluate the changes in middle ear pressure brought on by anterior nasal packing causing altered eustachian tube performance.
Methods50 patients undergoing nasal surgery participated in an observational prospective study. All patients having normal tympanometry preoperatively were included and again assessed postoperatively twice, once with the pack in situ and once 6 h after pack removal. All nasal packs were removed 24 h following surgery.
ResultsThe observations obtained were analysed and tabulated. All patients showed Type A tympanometry in both ears prior to their respective surgeries. A significant change was seen between preoperative tympanogram versus post-operative tympanogram with pack in situ with respect to the impact of middle ear pressure on anterior nasal packing. No significant change was seen between preoperative tympanogram versus postoperative tympanogram after pack removal. A significant change was seen between post-operative tympanogram with pack in situ versus post-operative tympanogram after pack removal in both ears.
ConclusionsFrom the above-mentioned results, it is concluded that the middle ear pressure variations caused due to the anterior nasal pack were resolvable. It is also concluded that the period of 24 h of placing the anterior nasal pack is safe and will not lead to chronic middle ear pathology even after pack removal.
