27%

9%

In the context of the rule of nines, which is a method used to estimate the total body surface area (TBSA) affected by burns, the head and neck are allocated a specific percentage. According to this rule, the head and neck collectively represent 9% of the total body surface area. This percentage is part of the larger assessment that divides the body into sections, with each section corresponding to a specific percentage that adds up to 100%.

Understanding the rule of nines is crucial for medical professionals, especially in emergency settings, as it helps in assessing the severity of burns and determining the appropriate treatment and fluid resuscitation required. The method simplifies calculations and provides a quick reference, ensuring efficient and effective patient care in cases of burn injuries.
