Extending the limits of reconstructive microsurgery in elderly patients

Area of Science:

• Microsurgery
• Plastic Surgery
• Geriatric Medicine

Background:

• Population aging impacts industrialized nations, challenging traditional views on surgical feasibility for older adults.
• Microsurgical procedures, once thought limited to younger patients, are now recognized as beneficial for the elderly.
• Age-related comorbidities were previously a concern for microsurgical procedures due to duration and vascular risks.

Purpose of the Study:

• To evaluate the safety and efficacy of microsurgical free tissue transfer in patients aged 78 years and older.
• To analyze patient characteristics, flap survival rates, and postoperative complications in a geriatric cohort undergoing free flaps.
• To determine the impact of age and comorbidities on outcomes of microsurgical procedures in elderly patients.

Main Methods:

• Retrospective investigation of a patient cohort (n=25, 27 free flaps) with a minimum age of 78 years.
• Analysis of patient demographics, flap survival, and surgical/medical complications post-procedure.
• Assessment of factors including age, operation time, and ASA score in relation to complication rates.

Main Results:

• Median patient age was 81 years; most defects were in the head and neck region.
• Flap failure occurred in 11% of cases; mortality rate was 4%.
• Postoperative surgical complications were observed in 41%, and medical complications in 70%, with no significant correlation to age, operating time, or ASA status.

Conclusions:

• Free tissue transfer is a justifiable curative option for very old patients needing structural and functional restoration, especially when alternatives are limited.
• The procedure aims to maximize patient independence and early ambulation, contributing to quality of life in aging populations.
• Optimizing patient selection and perioperative management is crucial for mitigating complication risks in elderly patients undergoing free tissue transfer.
