Abstract

Abstract



Background Condition of loss of graft after head and neck tumor surgery with free flap
reconstruction. This affects the patient's quality of life after surgery and also increases the
risk of repeat anesthesia to recover tissue. Therefore, after surgical tissue transfer, accurate
and efficient methods for monitoring and monitoring the ischemic state of the grafted tissue are
required.


Objectives To study the accuracy of postoperative free flap monitoring with Near-infrared
spectroscopy (NIRS) compare with the pin-prick method. To study factors associated with the
postoperative graft loss and the association of the two methods of monitoring.
Materials and methods Diagnostic descriptive study in a group of patients with head and neck tumors
who received tumor surgery with free flap reconstruction and postoperative free flap monitoring
with NIRS compare with the pin-prick method within 72 hours in the Otolaryngology Department,
Rajavithi Hospital. The data was collected between October 2022 and December 2023.


Results A total of 34 patients were found to have a tendency to lose a graft after surgery in 5
cases, which could be detected by using NIRS, with tissue oxygen levels lower than 60% in all
cases. It is an accuracy value equal to 100% compared to pin-prick method, and found that smoking,
blood loss during surgery, and the tissue oxygen level after surgery are the factor that has a
statistically significant relationship with postoperative free flap failure, with p-values equal to
0.015, 0.018, and 0.000, respectively.


Conclusion The NIRS for measuring the tissue oxygen level after surgery has the potential to be
used for postoperative free flap monitoring.
