  • infections
  • Sinus infections can be caused by viruses or bacteria and are exacerbated by allergies, foreign bodies, or structural abnormalities. (spokesman-recorder.com)
  • Because sinus infections are so common, knowing about them will allow you to recognize the symptoms in yourself or others and therefore be able to seek treatment sooner. (spokesman-recorder.com)
  • The sinuses do surround vital structures, so their infections can cause life-threatening problems such as periorbital (around the eye) or brain abscess or pus, loss of vision or meningitis. (spokesman-recorder.com)
  • In the past, studies have shown that this leads to continued function of the sinus and nasal cilia to clear sinus infections. (spokesman-recorder.com)
  • Untreated allergies are one of the main contributing factors to the development of sinus infections. (wikipedia.org)
  • Sinus infections can also cause middle ear problems due to the congestion of the nasal passages. (wikipedia.org)
  • Endoscopic
  • He is an expert in endoscopic sinus and laryngeal/voice surgery. (wikipedia.org)
  • In 1994, on a WHO fellowship, he worked with David W. Kennedy in the University of Pennsylvania Medical Center and learned functional endoscopic sinus surgery (FESS). (wikipedia.org)
  • meninges
  • verification needed] The confusion occurs in part because migraine involves activation of the trigeminal nerves, which innervate both the sinus region and the meninges surrounding the brain. (wikipedia.org)
  • bones
  • The sinuses are named for the facial bones in which they are located. (wikipedia.org)
  • The biological role of the sinuses is debated, but a number of possible functions have been proposed:[citation needed] Decreasing the relative weight of the front of the skull, and especially the bones of the face. (wikipedia.org)
  • The bones occupied by sinuses are quite variable in these other species. (wikipedia.org)
  • pterygoid notch pterygoid fossa scaphoid fossa pterygoid hamulus pterygoid canal pterygospinous process sella turcica The sphenoid articulates with the frontal, parietal, ethmoid, temporal, zygomatic, palatine, vomer, and occipital bones and helps to connect the neurocranium to the facial skeleton. (wikipedia.org)
  • Skull fractures occur more easily at the thin squamous temporal and parietal bones, the sphenoid sinus, the foramen magnum (the opening at the base of the skull that the spinal cord passes through), the petrous temporal ridge, and the inner portions of the sphenoid wings at the base of the skull. (wikipedia.org)
  • Outline of bones of face, showing position of air sinuses. (wikipedia.org)
  • obstruction
  • Therapy is directed toward relief of the sinus ostial obstruction and restoration of the normal mucociliary clearance. (jaoa.org)
  • symptoms
  • What are the common symptoms of paranasal sinus cancer? (healthtap.com)
  • Often a localized headache or toothache is present, and it is these symptoms that distinguish a sinus-related headache from other types of headaches, such as tension and migraine headaches. (wikipedia.org)
  • venous
  • Thus composition of gas content in the maxillary sinus is similar to venous blood, with high carbon dioxide and lower oxygen levels compared to breathing air. (wikipedia.org)
  • Linear skull fractures are usually of little clinical significance unless they parallel in close proximity or transverse a suture, or they involve a venous sinus groove or vascular channel. (wikipedia.org)
  • The resulting complications may include suture diastasis, venous sinus thrombosis, and epidural hematoma. (wikipedia.org)
  • endoscopic sinus
  • As endoscopic sinus surgery continued to advance, it was not long until an endoscopic medial maxillectomy was described. (medscape.com)
  • He is an expert in endoscopic sinus and laryngeal/voice surgery. (wikipedia.org)
  • In 1994, on a WHO fellowship, he worked with David W. Kennedy in the University of Pennsylvania Medical Center and learned functional endoscopic sinus surgery (FESS). (wikipedia.org)
  • Outcomes from the first prospective, multi-center, randomized controlled trial with sufficient statistical power to compare sinus dilation to functional endoscopic sinus surgery were published in the American Journal of Rhinology & Allergy in 2013 and 2014. (wikipedia.org)
  • The balloon technique is an alternative, less invasive treatment than the traditional functional endoscopic sinus surgery (FESS). (wikipedia.org)
  • carotid
  • carotid sinus a dilatation of the proximal portion of the internal carotid or distal portion of the common carotid artery, containing in its wall pressoreceptors that are stimulated by changes in blood pressure. (thefreedictionary.com)
  • ostium
  • The results of experimental studies suggest that the natural ventilation-rate of a sinus with a single sinus ostium (opening), is extremely slow. (wikipedia.org)
  • coronary
  • coronary sinus the dilated terminal portion of the great cardiac vein, receiving blood from other veins draining the heart muscle and emptying into the right atrium. (thefreedictionary.com)
  • tissue
  • 1986 - "Magnetic Resonance Imaging [using a 1.5 Tesla (15,000 Gauss) magnet and a spin echo technique] has revealed a remarkably intense signal from abnormal tissue in the human paranasal sinuses. (sindamag.com)
  • The sinuses are dilated with a balloon instead of using metal instruments to cut and remove tissue to increase the openings. (wikipedia.org)
  • A sinus is a sac or cavity in any organ or tissue, or an abnormal cavity or passage caused by the destruction of tissue. (wikipedia.org)
  • rhinosinusitis
  • Balloon and surgical patients experienced a similar, significant level of: symptom improvement decline in number of rhinosinusitis episodes requiring medication in year after treatment improvements in work productivity and activity level Patients who had balloon sinus dilation experienced a much quicker recovery, less bleeding, and less need for prescription pain medication. (wikipedia.org)
  • Recurrent
  • Consider imaging studies in recurrent or unclear cases: some sinus involvement is frequent early in the course of uncomplicated viral URI Treatment comprises symptomatic support usually via analgesics for headache, sore throat and muscle aches. (wikipedia.org)
  • mucosal
  • Such limited ventilation may be protective for the sinus, as it would help prevent drying of its mucosal surface and maintain a near-sterile environment with high carbon dioxide concentrations and minimal pathogen access. (wikipedia.org)
