Eustachian tube dysfunction symptoms after endonasal skull base surgery

Area of Science:

• Otolaryngology
• Neurosurgery
• Skull Base Surgery

Background:

• Eustachian tube dysfunction (ETD) can significantly impact quality of life.
• Skull base pathologies present unique challenges for diagnosis and treatment.
• The relationship between skull base pathology and ETD requires further investigation.

Purpose of the Study:

• To determine the prevalence of ETD symptoms in patients with skull base pathology.
• To assess the impact of surgical intervention for skull base pathology on preoperative ETD symptoms.
• To identify specific skull base pathologies associated with ETD symptom exacerbation.

Main Methods:

• Retrospective chart review of patients with diagnosed skull base pathology.
• Preoperative and postoperative assessment of Eustachian tube dysfunction (ETD) symptoms using standardized questionnaires.
• Correlation analysis between skull base lesion characteristics (location, malignancy) and ETD symptom severity.

Main Results:

• 16% of patients with skull base pathology reported symptoms of ETD.
• Significant improvement in ETD symptoms was observed postoperatively in the majority of patients.
• Central, posterior, or malignant skull base pathologies were associated with a higher incidence or worsening of ETD symptoms.

Conclusions:

• ETD is a notable comorbidity in patients with skull base pathology.
• Surgical management of the underlying skull base pathology can effectively alleviate ETD symptoms.
• Specific tumor locations and malignant characteristics of skull base lesions may predict or exacerbate ETD.
