Basic Research and Clinical Application of Pterygoplatione Fossa Projection on Lateral Nasal Wall.
Infection, neoplasms, and tumor-like lesion in pterygoplatione fossa (PPF) are common in Chinese people. Owing to its deep anatomic location, surgery through this region is difficult. Maxillary sinus pathway is widely used, but the obvious disadvantage of destroying maxillary sinus even disfigurement cannot be avoided. This study provides a new method to locate PPF by choosing some landmarks situated at lateral wall of nasal cavity as reference points to obtain credible and detailed information for clinical management. The authors measured the location of anterior wall, posterior wall, and medial wall of PPF in the planes of middle nasal concha osseous extremity, inferior nasal concha osseous extremity, and middle nasal meatus. In addition, the authors measured the distance and the angle between the upper and lower bound of the PPF and the apertura sinus maxillaris. All PPF and landmarks of 196 patients were well demonstrated on computed tomographic angiography images. The new location method is stable and direct. As for the shape of PPF, the line connecting anterior wall in different planes is curve, convex backward, and concave frontward. Pterygoplatione fossa tapers gradually. The authors also found that with the traditional method, after entering the maxillary sinus, the needle should be inserted <26 mm when aimed at the upper bound and 30 mm in women and 31 mm in men when aimed at the lower bound.
