Summary
Middle ear barotrauma affects 68.7% of patients undergoing hyperbaric oxygenation therapy. Objective examination is crucial, as subjective symptoms may be missed in certain patient groups.
Area of Science:
- Otolaryngology
- Hyperbaric Medicine
Background:
- Middle ear barotrauma is a potential complication of hyperbaric oxygenation (HBO) treatment.
- Understanding its incidence and predisposing factors is essential for patient safety.
Purpose of the Study:
- To investigate the signs and symptoms of middle ear barotrauma in patients undergoing HBO therapy.
- To assess the influence of predisposing factors on barotrauma incidence and severity.
Main Methods:
- A study of 67 patients undergoing HBO treatment.
- Classification of ear damage into 5 grades based on otoscopic examination findings.
- Comparison of objective findings with subjective patient-reported symptoms.
Main Results:
- The incidence of middle ear barotrauma, based on objective criteria, was 68.7%.
- Age and primary disease showed minimal influence on objective barotrauma incidence.
- Subjective symptom reporting was less reliable in older patients, those with severe neurological diseases, and those with speech difficulties.
Conclusions:
- Otoscopic examination is recommended for all patients undergoing HBO treatment.
- Proactive management of nasal and paranasal diseases can aid in preventing and treating middle ear barotrauma.
