Dear Sir:

Surgical procedures involving the anterolateral wall of the maxillary sinusanddissections carried out in this region allow us to observe the presence of a vascular structure which may reach such dimensions as to qualify as a "risk structure" when surgery is carried out in this site.

It is reported in the literature that this anatomical structure is frequently compromised during surgical elevation of the maxillary sinus,the Caldwell-Luc procedure and the Le Fort I osteotomy(Rahpeyma & Khajehahmadi, 2014).

This artery was described in the literature as far back as1934 by Strong(1934), who stated that it was responsible for irrigating both the teeth and the antral mucosa, and that what might be called the "antro-dental plexus" is formed in this region.

According to different studies, this artery represents an intraosseous anastomosis between the superior posterior alveolar artery, a branch of the maxillary artery, and the infraorbital artery, level with the anterolateral wall of the maxillary sinus(Rahpeyma & Khajehahmadi; Maridati et al., 2014).

This important anatomical structure is given the name "alveolar antral artery" in most scientific studies today, however this term is not included in Terminologia Anatomica.

The fact that the clinical existence of this important anatomical structure has been reported but that it is not included in Terminologia Anatomica may lead to confusion among those who teach anatomy and surgery when they have to describe it.

We hope that this vascular structure will be included in Terminologia Anatomica in the near future, as this will facilitate teaching and learning, preventing misunderstandings in scientific communication and supporting our everyday work by stimulating knowledge and use of Terminologia Anatomica.
