The authors show the interest of C.T. examination of pterygo-maxillary region, principally in the pre-therapeutic staging of the maxillo-facial neoplasy. The anatomical division of the fossa in four regions (pterygoïd muscle area, lateropharyngeal area, pterygo-palatine fossa and retro-maxillary-malar area) can be easily applied to C.T. study. Cuts must be taken axially, in the orbito-meatal plane, and coronally always if possible, before and after administration of contrast medium. Six, out of thirty six cases studied were demonstrative. It appears that C.T. examination must be performed immediately after conventional radiology in the staging of maxillo-facial neoplasy. It shows with considerable accuracy not only the bony involvement, but also the extension in the soft tissues (interest of the densitometric study of fat) and aeric structures. It sometimes brings the solution of special clinical problems (Trismus, neuralgia of the facial nerve).
作者展示了翼上颌区域CT检查的意义，主要用于颌面肿瘤的治疗前分期。将该窝分为四个区域（翼肌区、咽旁区、翼腭窝和上颌后颧骨区）的解剖划分可轻松应用于CT研究。必须在眶耳平面进行轴向扫描，并尽可能在注射造影剂前后进行冠状扫描。在研究的36例病例中，有6例具有典型表现。似乎在颌面肿瘤分期时，CT检查必须紧接在传统放射学检查之后进行。它不仅能相当准确地显示骨质受累情况，还能显示软组织的扩展情况（脂肪密度测定研究的意义）以及含气结构。它有时能解决特殊的临床问题（牙关紧闭、面神经痛）。
