A balloon dilation catheter includes a substantially rigid inner guide member and a movable shaft coupled to a balloon that is slidably mounted on the substantially rigid inner guide member. To treat a sinus cavity of a subject using the balloon dilation the substantially rigid inner guide member is advanced into a drainage pathway of the sinus (e.g., frontal recess or maxillary sinus) of the subject via a nasal passageway. The shaft and balloon are advanced in a distal direction over the substantially rigid inner guide member to place the balloon in the drainage pathway. The balloon is inflated to expand or otherwise remodel the drainage pathway.

FIELD: otorhinolaryngology.SUBSTANCE: under endotracheal anesthesia, an endoscope equipped with optics and an instrument for removing pathological contents of the maxillary sinus are inserted into the nasal passage. The inferior nasal concha is displaced medially using a raspatory. Then, stepping back from the edge of the piriform opening by 1.5–2.0 cm in the caudal direction, a mucoperiosteal flap of the lateral wall is separated in the lower nasal passage. The mucoperiosteal flap is displaced posteriorly, exposing the bone skeleton in the projection of the inferomedial angle of the maxillary sinus. Next, using a cold plasma coblator, in ablation mode, the mucous surface of the bone skeleton is evaporated for 2–3 seconds, followed by coagulation of small vessels. Then, a bone valve measuring 10–15 mm is formed from the exposed bone skeleton. The bony valve is retracted in the caudal direction, forming an antrostomy. A 70-degree endoscope is inserted through the formed antrostomy and the pathological contents of the sinus are visualized. In this case, if the cyst is visualized with a coblator in ablation mode, the cyst is evaporated along with its contents, and the remaining cyst is captured and removed. If a polyp is visualized, the polyp stalk is first evaporated, and then the remaining part of the polyp is removed. If a foreign body is visualized, it is removed with forceps. In this case, if the foreign body is encapsulated or located in the thickness of the mucosa, a coblator in ablation mode evaporates part of the mucosa until the foreign body is exposed, and then removed. Next, the sinus cavity is washed with saline solution. The antrostomy is closed with a bone flap. The formed mucoperiosteal flap is placed back in its original place.EFFECT: method allows for endoscopic endonasal removal of pathological contents from the maxillary sinuses with a minimal risk of cyst / polyp recurrence and postoperative complications, reduced blood loss during surgery, shortened surgical time, postoperative rehabilitation periods, and temporary disability.3 cl, 3 ex

The invention discloses a sinus cavity analysis system based on a CT image, electronic equipment and a storage medium, and the system comprises a sinus cavity segmentation module which is suitable for carrying out the segmentation of a CT image of a craniocerebral part through a trained deep learning model, and obtaining the spatial structure information of a sinus cavity in the craniocerebral part; the model construction module is suitable for constructing a ball-stick model by taking the sinus cavities as balls and the channels between the sinus cavities as sticks according to the sinus cavity space structure information obtained through segmentation; and the smoothness analysis module is suitable for analyzing the smoothness between the sinus cavities according to the characteristics of the ball and the stick in the ball and stick model. According to the technical scheme, the space structure information of the sinus cavity of the craniocerebral part can be automatically extracted from the CT image, and errors and time consumption of manual operation are reduced; the sinus cavity is visually analyzed through the ball and stick model, the space structure and smoothness of the sinus cavity can be visually displayed, and the accuracy and efficiency of diagnosis are improved.

An equine browband headguard includes a frontal portion and first and second lateral portions devised to protect prominent portions of an animal's head during gameplay in contact sports such as polo. Frontal portion is devised to seat between the zygomatic arches on the animal's forehead to overlie a frontal bone of a pony (or other animal), protecting the sutures between the nasal bone, frontal bone, and parietal bone, as well as the sinus cavity thereunder. First and second lateral portions are devised to overlie temporomandibular joints. The equine browband headguard is devised to install into an existing bridle with minimal reconfiguration, essentially replacing an existing browband. The equine browband headguard has been devised to present a low-profile, elegant addition to the tack of sporting animals engaged in contact sports like polo and may present a surface for team insignia or branding.

An implant for a sinus cavity that can have a main body portion and a second body portion coupled with the main body portion. In some embodiments, the second body portion can extend at an angle away from the main body portion. The implant can be sized and configured for implantation in the frontal sinus. A size and a shape of the implant can be similar to a size and a shape of the frontal sinus of a patient that the implant will be implanted into.WO
