Dentistry · Oral pathology: cysts and odontogenic tumours: central haemangioma of the jaw
Sample itemA 16-year-old has profuse bleeding around the gingival margin of a mobile lower molar, a palpable pulsation over the mandible and a honeycomb radiolucency. What should be done first?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
B. Needle aspiration for blood, then vascular imaging, before any surgery
A central vascular malformation of the jaw can bleed massively if the tooth is extracted or the lesion curetted. Aspiration of blood and angiography are done first and treatment is planned with embolisation or resection.
Option by option
A. Incisional biopsy in the clinic
A blind incisional biopsy risks the same bleeding.
B. Needle aspiration for blood, then vascular imaging, before any surgery (correct)
Correct. Confirm the vascular nature and map the vessels before any procedure.
C. Curettage of the lesion through the socket
Curettage of a vascular lesion causes uncontrolled haemorrhage.
D. Extract the mobile molar to control the bleeding
Extraction can cause life-threatening haemorrhage from the lesion.
