Background and aims: Postoperative haematoma formation is a fortunately rare but potentially life-threatening complication of thyroid surgery. This paper aims to identify potential aetiological factors, describe surgical techniques and newer haemostatic agents that may be used to minimise the risk of haematoma formation and propose surgical strategies to deal with haematoma formation.
Materials and methods: An extensive literature search as well as own considerable experience in a tertiary referral centre endocrine surgical unit was drawn upon to review this topic.
Conclusions: Postoperative haematoma may have a multifactorial aetiology. Numerous manoeuvres and surgical haemostatic agents may be employed to minimise the risk of haematoma formation but are no substitute for meticulous haemostasis. In the event of haematoma formation, early surgical re-intervention is strongly advocated with due care given to at risk structures.
