Rhinogenic headaches are not unfamiliar to everyone, and are most commonly caused by rhinitis and sinusitis. Do you know about rhinogenic headache? Do you know what tests should be done? We look at the examination methods of rhinogenic headache: 1. Nasal cavity examination: anterior rhinoscopy, may see chronic congestion, swelling or hypertrophy of the nasal mucosa, hypertrophy or polypoid change of the middle turbinate, narrowing of the middle nasal tract, mucosal edema or polyps, etc. In anterior sinusitis, there is pus in the middle nasal tract; in maxillary sinusitis, pus is usually in the lower part of the middle nasal tract, and may flow down the inferior turbinate and accumulate in the bottom of the nasal cavity and the inferior nasal tract. In frontal sinusitis, pus mostly flows down from the anterior segment of the middle nasal tract. In the anterior group of septal sinusitis, mucous pus is seen in the middle nasal tract. In posterior sinusitis, the pus flows down from the olfactory fissure and is retained in the posterior part of the nasal cavity or flows into the nasopharynx. If necessary, a posterior rhinoscopy should be performed, which can help to observe whether there is pus in the upper nasal tract. If septic sinusitis is suspected and no pus is seen in the nasal tract, 1% ephedrine can be used to shrink the nasal mucosa and then make a postural drainage method to help diagnose. The use of fiberoptic nasopharyngoscopy or nasal-sinus endoscopy auxiliary examination, observation of the mucosal changes in the walls of the nasal cavity and the opening of the sinuses, as well as the secretions of the sinus mouth, is more helpful in the diagnosis. 2. Oral and pharyngeal examination: In case of odontogenic maxillary sinusitis, lesions may be detected in the ipsilateral maxillary 2nd bicuspid or 1st and 2nd molars. Posterior group sinusitis is sometimes seen with purulent secretions or dry crusts on the posterior pharyngeal wall. 3, X-ray sinus film and tomography: one of the important methods to diagnose sinusitis, but should be combined with clinical symptoms to help the diagnosis. When suffering from sinusitis, the mucous membrane in the sinus has different degrees of thickening, so the X-ray film can still show the size and shape of the sinus cavity, which is more valuable for those who need to perform surgical treatment. If necessary, iodine oil imaging of maxillary sinus can be performed to make a clearer diagnosis. 4, sinus puncture rinse or catheter rinse method: maxillary sinus, frontal sinus and butterfly sinus can be placed through its sinus mouth catheter for rinse and instillation of drugs, but because of the complex anatomical relationship, operation techniques are difficult, often not easy to succeed. Sinus puncture and irrigation is most commonly used in the maxillary sinus, while puncture of other sinuses is rarely used due to the high risk. Through the maxillary sinus puncture irrigation can understand the nature of the pus in the sinus, how much, whether there is malodor, and can be used for bacterial culture and drug sensitivity test, according to infer the degree of sinus lesions and develop a treatment plan. 5.CT scan: When examining sinusitis, it is possible to clearly observe whether the sinus wall is damaged and the degree of mucosal lesions in the sinus cavity. 6.Sinus ultrasonography: It is a new diagnostic technique for maxillary sinus and frontal sinus examination, A-type ultrasonography is non-invasive and painful, simple, rapid, and repeatable. It can detect fluid, polyps or tumors in the sinus cavity. 7, maxillary sinus endoscopy: the examination is the latest method to diagnose lesions, applied in the 70s, can be taken in the sinus pathology biopsy under cold light source illumination, or film, video, can overcome the blindness of the examination, improve the diagnosis rate. The above is the examination method of rhinogenic headache introduced to you today, I believe you have already understood, sincerely hope that our sharing can really help you, we hereby remind all friends, if you find discomfort, please go to the regular hospital for examination and treatment in time, so as not to miss the best time for treatment. We wish every one of you a good health!
