Insights

Single-stage delayed free flap reconstruction significantly improved quality of life, aesthetics, speech, and swallowing in patients with COVID-19-associated mucormycosis rhino-orbito-maxillary defects. This procedure offers considerable functional and aesthetic recovery.

Area of Science:

  • Plastic Surgery
  • Otolaryngology
  • Infectious Diseases

Background:

  • The second wave of COVID-19 in India led to a surge in COVID-19-associated mucormycosis.
  • This fungal infection often necessitates extensive surgical debridement, resulting in complex maxillofacial defects.
  • Reconstruction of these defects presents a significant clinical challenge.

Purpose of the Study:

  • To evaluate the clinical outcomes of single-stage delayed free flap reconstruction in patients with rhino-orbito-maxillary defects.
  • To assess improvements in quality of life, aesthetics, speech, and deglutition post-reconstruction.

Main Methods:

  • A prospective, single-center study involving eight patients with COVID-19-associated rhino-orbito-maxillary mucormycosis.
  • Free flap reconstruction was performed as a single-stage delayed procedure.
  • Outcomes were assessed using validated questionnaires (QOL, ANA, Glasgow scale) at 1 and 3 months post-surgery.

Main Results:

  • All patients had diabetes mellitus; 75% were male, with a median age of 40 years.
  • Maxillary defects were common, with 50% being bilateral.
  • Significant improvements in quality of life (QOL) and aesthetics (ANA scale) were observed (p < 0.001).
  • Speech and deglutition showed improvement at 3 months, though not statistically significant.

Conclusions:

  • Single-stage delayed free flap reconstruction is a viable option for managing complex defects from COVID-19-associated mucormycosis.
  • The procedure leads to considerable improvements in patient quality of life, aesthetics, speech, and swallowing over time.
