Abstract

Aim: The aim of this work is to analyze the frequency of changes in tympanometry in adults with deviated nasal septum (DNS) and hypertrophied inferior turbinate before and after surgery.

Material and method: This prospective study included 35 adult patients with DNS and hypertrophied inferior turbinate who were candidates for septoplasty and submucous diathermy of the inferior turbinate (SMD). The analysis concerned the morphology of DNS (division according to Mladina), and its effect on middle ear pressure (MEP) measured by tympanometry before and after operation.

Results: DNS type 2 and 3 with hypertrophy of inferior turbinate were the most common types each constituted 35.2% and were associated with type A tympanoram but DNS type 4 was less common 14.7 % and was associated with type c tympanogram mean (-112.5 mm H2O) . In the 1st postoperative day MEP become more negative (-71.02 ±33.34) in the right ear and (-65.75±24.6) in the left ear before removal of the nasal pack and become (-51.17±32.61) and (-48.82±23.90) respectively after pack removal. MEP dropped below the base line tympanogram after the 1st and 2nd weeks postoperative.

Conclusions: different types of DNS associated with hypertrophy of the inferior turbinate affects MEP. Septoplasty with SMD causes significant improvement of the auditory tube function and hence the MEP (p < 0.05) after 1 week. Nasal packing causes significant worsening of the MEP so avoidance of the nasal packing or the use of nasal pack with integral pathway could minimize this problem.

Keywords: Nasal septum, inferior turbinate, tympanometry, septoplasty, SMD.
