[Oradlist] Input for maxillary implant imaging request

[Allan G Farman]

Elaine: I am not aware of any research either. I can understand that raising the membrane can on occasion lead to occlusion of the ostea of the maxillary sinuses; however, I cannot fathom why the other ostia need to be included in the image for maxillary implant placement unless the practitioner is referring all patients for a complete paranasal sinus evaluation by an ENT specialist. If the latter is the case, then one would need to decide whether in your region this imaging request does indeed fit within the scope of Oral and Maxillofacial Radiology. I do read all paranasal sinuses; however, that is when they are incidentally included in the volume rather than planned to be in the volume specifically for evaluation of these additional sinuses. I think that you need to contact this practitioner for an explanation of the rationale behind the request. AGF

According to the referring dentist and at least some ENT's, the osteomeatal complex includes not only the maxillary ostia, but also the?ethmoids and the?frontal ostia - hence the overly high scan needed to achieve the image he wants.? I'm not aware of any research supporting the need for this protocol - is anyone else aware of any?? I suppose I can understand wanting to see the maxillary ostia for sinus lift cases?even in the absence of?supporting data, but for all maxillary implant cases?? Presumably preoperative panoramic or periapical radiographs determine whether a sinus lift will be considered, and even if it is I don't see a need to include the orbits just to meet?a?scientifically?unjustified?"entire osteomeatal complex" derived by an implantologist.
