Summary
The Patulous Eustachian Tube Handicap Inventory (PHI 10) effectively assesses severity in patients with patulous Eustachian tube (PET). Surgical treatment showed significant improvement compared to conservative methods.
Area of Science:
- Otolaryngology
- Medical device evaluation
- Patient-reported outcome measures
Background:
- Patulous Eustachian tube (PET) significantly impacts quality of life.
- Objective assessment tools are crucial for evaluating PET severity and treatment efficacy.
Purpose of the Study:
- To evaluate the efficacy of the Patulous Eustachian Tube Handicap Inventory (PHI) for patients diagnosed with definite PET.
- To assess the suitability of the PHI, specifically the PHI 10, for grading severity and evaluating treatment outcomes.
Main Methods:
- A prospective study involving 31 PET patients undergoing surgical plug insertion and 29 patients receiving conservative saline treatment.
- The Patulous Eustachian Tube Handicap Inventory (PHI), modified from the Tinnitus Handicap Inventory, was used for assessment.
- PHI 10 scores were analyzed pre- and post-treatment for surgical cases and compared between groups.
Main Results:
- PHI 10 scores were significantly lower in the surgical group (19.5 ± 9.3) compared to the conservative group (30.6 ± 8.6) pre-treatment.
- Post-surgery, PHI 10 scores in the surgical group dramatically decreased to 7.8 ± 11.3, indicating significant improvement.
- The PHI 10 demonstrated good internal consistency (Cronbach's α = 0.887) and correlated well with a Likert scale.
Conclusions:
- The PHI 10 is a reliable and valid tool for assessing the severity of definite patulous Eustachian tube.
- The PHI 10 is suitable for evaluating the effectiveness of surgical interventions for PET.
