What is the Walsh position?

Walcott's position is also known as the posterior anterior 37 angle position of paranasal sinuses. The maxillary sinus and the posterior ethmoid sinus are mainly observed, and the frontal sinus and the anterior ethmoid sinus are also developed, which is the routine X-ray posture for examining paranasal sinuses.

Photographing position: The examinee lies prone on the photographic bed, with the sagittal plane of his head perpendicular to the bed surface and coincident with the center line of the bed, his head tilted upward, so that the auditory canthus line makes an angle of 37 with the bed surface, and the chin of the mandible is placed on the bed for photographing.

The photo shows that the bilateral maxillary sinuses are symmetrically displayed with inverted triangular shadows under the orbit and above the petrous part of the temporal bone, and the density of normal maxillary sinus images is similar to that of the orbit. The frontal sinus is displayed in the upper part of the orbit. The honeycomb shadow between the orbits is the anterior ethmoid sinus, and the sides of the nasal cavity are the posterior ethmoid sinus. Sometimes if you want to observe the liquid level in the sinus cavity, you can take paranasal sinus photography in an upright position.

Sinusitis has a runny nose and stuffy nose. In severe cases, it will cause dizziness and headache. The sinus is distributed in the head, and it is distributed like a butterfly on the nose, cheeks and forehead.

Sinusitis simply means that there is inflammation, effusion and pus in the sinuses, and the inflammation in the forehead will cause pain near the temple, which can usually be relieved by some methods; When you have a headache, you can apply cold compress to your forehead and neck and gently massage your temples with your hands and fingers. This method can temporarily relieve the symptoms of headache.

Extended information:

Acute sinusitis is mostly caused by upper respiratory tract infection, and bacterial and viral infections can be concurrent. The common bacterial flora is streptococcus pneumoniae, streptococcus hemolyticus and staphylococcus, followed by Haemophilus influenzae and Moraxella catarrhalis, the latter is common in children. Other pathogenic bacteria include streptococcus, anaerobic bacteria and staphylococcus aureus. Most people caused by dental diseases are infected by anaerobic bacteria, and pus often smells bad. Fungi and allergies may also be pathogenic factors.

The infection of acute sinusitis often comes from sinus infection, nasal infection, adjacent tissue infection, blood-borne infection, traumatic infection, as well as systemic factors and poisoning factors.
