Roof of digastric triangle.

The roof of the triangle is formed the skin superficial cervical fascia the platysma and deep cervical fascia. The branches of the facial nerve and transverse cutaneous cervical nerves also pass over the roof of the triangle. Contents in the anterior part of the triangle. The digastric triangle is one of the paired triangles in the anterior triangle of the neck.

Platysma cervical division of facial nerve and ascending branch of transverse cervical nerve are located in the superficial fascia above the roof. Skin superficial fascia platysma 17.
