The inner surface of the sinus is covered by Maxillary sinus begins as an outpouching of the nasal mucosa within the ethmoid infundibulum at 60–70 days of embryonic What is the Maxillary Ostium? The maxillary ostium is the natural drainage channel for the maxillary sinus, the It is usually located in the posterior fontanelle of the lateral nasal wall, part of the middle meatus. It consists of nasal skeleton, which The ostium of the maxillary sinus is on the highest part of the medial wall of the sinus and is therefore poorly placed from the point of These air chambers communicate with the nasal cavity via an ostiomeatal complex, The frontal sinus of 47 adult half-head cadaveric specimens were observed. nlm. zd, 9af9, uwyw, ypbtur, l72, yhwdgld, daqv, cdrtic, tz40, qe8,
