Objectives:
To investigate the effect of nasal obstruction surgery on eustachian tube function and middle ear ventilation.
Design:
Prospective study.
Setting:
University Campus Bio-Medico of Rome.
Participants:
Forty consecutive patients who underwent nasal surgery were evaluated for middle ear ventilation and tubal function.
Main Outcome Measures:
Pre- and postoperative Valsalva and Toynbee tubal function tests, tympanometry and ear fullness sensation were evaluated for both ears of each patient.
Results:
Results of postoperative tubal function tests were significantly better than preoperative ones (90% versus 46%; P<0.001). No significant difference in tympanometric values was found. The majority (95%) of the patients reported a postoperative improvement of ear fullness sensation compared with preoperative (25%; P<0.001).
Conclusions:
Surgery for chronic nasal obstruction significantly improves clinical tubal function but 1-month postoperative tympanometric findings remain almost the same.
