Summary and Conclusion
The deviated nasal septum may be associated with middle ear
problems. particularly on the side of the nasal obstruction. This study
aims to: find out whether middle ear pressure (MEP) correlates with
the degree of nasal obstruction secondary to a deviated nasal septum •
and to examine changes in middle ear pressure fOllOWingseptal surgery
. In this study • 50 patients complaining of longstanding nasal obstruction
due to deviated nasal septum were included.
They are divided into two groups:
* Study group ”A” ( 40 patients) with abnonnal negative middle
ear pressure .
* Control group ”B” (10 patients) with normal middl ear pressure.
All patients were subjected to the following:
1 - Detailed history .
2 - Full otorhinolaryngological examination that included nasal endoscopy.
3 - Plain X- ray sinus view.
4 - Preoperative tympanometry using an American Electromedics AE
106 tympanometer .
5 - Septal surgery .
6 - Postoperative tympanometry using the same tympanometer.

Results obtained could be summarised as follow :
* In study group (A) 60 % of the diseased ears were found on the
same side of the obstructed nasal passage.
In the ear on the side of nasal blockage,middle ear pressure was _
64.4 ± ”84.8 rom water preoperatively , and following surgery increased
significantly to - 30.5± 39.Irom water (mean ± SD) .
In the ear contralateral to the side of nasal blockage .middle ear
pressure was -59±71.1 rom water preoperatively, and following surgery
increased significantly to - 20.2 ± 37.7 rom water (mean + SD).
* In control group (B) , all the patients exhibited no significant
change in middle ear pressure in either ear following the septal surgery.
• In conclusion, It was apparant that the patients with a deviated
nasal septum may have associated middle ear disorders , particularly
in the ear ipsilateral to the obstructed nasal passage . Correction of this
deformity by septal surgery led to a corresponding improvement in
middle ear pressure.
