Sensorineural hearing loss (SNHL) is a rare complication after cardiac surgery, affecting adults and children. Hearing loss often impacts high frequencies and may require further research into screening for pediatric patients.
Area of Science:
- Otolaryngology
- Cardiology
- Pediatrics
Background:
- Sensorineural hearing loss (SNHL) is a potential complication following cardiac surgery.
- Limited guidelines exist for preventing post-operative complications like SNHL.
- This review characterizes SNHL after cardiac surgery.
Approach:
- Systematic review registered on PROSPERO, adhering to PRISMA guidelines.
- Comprehensive search of PubMed, Embase, and Cochrane Library.
- Duplicate determination of eligibility, data extraction, and quality analysis.
Key Points:
- 23 studies reviewed, encompassing adult and pediatric populations.
- Adults: 5.05 cases/1000 operations (36/7135); 56.6% mild SNHL.
- Pediatrics: 88 cases/1342 operations; 59.2% moderate or worse SNHL.
- Hearing loss predominantly affects high frequencies (>6000 Hz).
- SNHL associated with extracorporeal circulation, but also occurs without it.
Conclusions:
- SNHL is a rare but serious complication of cardiac surgery with long-term impacts.
- Affects both pediatric and adult patients.
- Further research is needed, especially regarding SNHL screening in children post-cardiac surgery.
