Sir, Senior House Officers in oral and maxillofacial surgery may be interested to know that they can access an online 3D anatomy service (www.anatomy.tv) by registering for free with Univadis at www.univadis.co.uk.

The website makes anatomy revision interesting and interactive, allowing the layers of the head and neck to be peeled back layer by layer. The image can then be rotated and magnified as required. MRI views and MCQs are also available to test what has been learned. The Univadis website offers other services besides this and is well worth a visit.

Please note that although the registration webpage asks for a GMC number, Univadis does offer membership to singly qualified dental surgeons working in the hospital service.
