to create an artificial passage into the maxillary sinus through the nose; puncture medial wall of inferior meatuses Tilly's antral bur: to enlarge the artificial passage into the maxillary sinus through the nose made by the harpoon trochar; dilate and smoothen the antrostomy opening Freer's double-ended mucoperichondrium elevator
Maxillary hypoplasia is the most common secondary deformity that results from cleft lip and cleft palate. Because of the subjective nature of the diagnosis, the incidence of maxillary hypoplasia in people with cleft lip and palate varies between 15-50%. It is estimated that 25-50% of these patients require surgical intervention. [7]
Silent sinus syndrome is a subtype of stage three chronic maxillary atelectasis. The distinguishing factor is that in silent sinus syndrome, there is an absence of sinusitis symptoms. [ 3 ] [ 4 ] [ 5 ] To be clear, chronic maxillary sinusitis may be a primary causitive factor in a significant number of silent sinus syndrome cases, it just may ...
The pyramid-shaped maxillary sinus (or antrum of Highmore) is the largest of the paranasal sinuses, located in the maxilla. It drains into the middle meatus of the nose [ 1 ] [ 2 ] through the semilunar hiatus .
Ultrasonography machine: uses ultrasound to produce images from within the body; video link: X-ray: uses X-rays to produce images of structures within the body; video link: Contrast media for X-rays: to provide a high contrast image of the details of the viscera under study; e.g. salts of heavy metals, gas like air, radio-opaque dyes, organic ...
An X-ray generator generally contains an X-ray tube to produce the X-rays. Possibly, radioisotopes can also be used to generate X-rays. [1]An X-ray tube is a simple vacuum tube that contains a cathode, which directs a stream of electrons into a vacuum, and an anode, which collects the electrons and is made of tungsten to evacuate the heat generated by the collision.
ZMC complex fractures involve the lateral vertical buttress of the ZMC complex (lateral maxillary sinus and lateral orbital wall) and the upper transverse buttress (inferior orbital rim and floor, also including the zygomatic arch). Three of its four components are directly related to connections between the zygoma and the face.
The most commonly involved tooth in localized microdontia is the maxillary lateral incisor, which may also be shaped like an inverted cone (a "peg lateral"). [3] Peg laterals typically occur on both sides, [2] and have short roots. [2] Inheritance may be involved, [2] and the frequency of microdontia in the upper laterals is just under 1%. [1]
