What causes nasopharyngeal stenosis?
Nasopharyngeal stenosis (NPS) may appear months to years after adenoidectomy or uvuloplasty or radiotherapy. It results from excess mucosal removal or scarring during surgery or radiotherapy followed by scar contracture and maturation. The degree and extent of the stenosis may vary from patient to patient.
What is nasopharyngeal stenosis?
Introduction. Complete nasopharyngeal stenosis (NPS) is a very rare condition that is characterized by the obstruction of the nasopharynx by submucosal fibrotic tissue from the soft palate and posterior pharynx [1].
What causes narrowing of the oropharynx?
Oropharyngeal stenosis (OPS) is a narrowing of the oropharynx as a result of adhesions from the base of the tongue to the anterior tonsillar pillars and inferior tonsillar fossa1. OPS can cause dysphagia, sleep disordered breathing, velopharyngeal incompetence due to tethering of the soft palate, and other symptoms.
What is nasopharyngeal stenosis dog?
Nasopharyngeal Stenosis in Dogs. Nasopharyngeal stenosis is a narrowing of one of the four portions of the nasal cavity on either side of nasal septum. Any of the four portions can be affected, which include the common, inferior, middle, and superior portions.
What is nasopharyngeal infection?
The most common condition that affects your nasopharynx is nasopharyngitis, otherwise known as the common cold. This swelling of your nasal passages and throat is sometimes called an upper respiratory infection, or rhinitis. In nasopharyngitis, a virus (often rhinovirus) infects your nasopharynx.
What is the role of the nasopharynx?
The main function of your nasopharynx is to connect your nasal passages to the rest of your respiratory system. This allows air to get from your nose to your lungs. Your nasopharynx also helps: Control pressure between your nasopharynx and middle ear.
How is laryngeal stenosis treated?
A case series reported by Blanchard et al indicated that congenital laryngeal stenosis can be treated safely and effectively using endoscopic laryngoplasty with incision of the subglottic laryngeal cartilages with cold steel instruments and balloon dilation.
Is there a treatment for nasopharyngeal?
Treatment of stage IV nasopharyngeal cancer may include the following: Chemotherapy given with radiation therapy, followed by more chemotherapy. Radiation therapy. Radiation therapy followed by surgery to remove cancer-containing lymph nodes in the neck that remain or come back after radiation therapy.
How do you treat nasopharynx pain?
How is viral nasopharyngitis treated?
- decongestants, like pseudoephedrine (Sudafed)
- decongestants combined with antihistamines (Benadryl D, Claritin D)
- nonsteroidal anti-inflammatory drugs, like aspirin or ibuprofen (Advil, Motrin)
- mucus thinners, like guaifenesin (Mucinex)
- lozenges to soothe a sore throat.
How do you treat nasopharynx?
The main treatment for NPC is radiation therapy. It is often given in combination with chemotherapy. This approach may be called concomitant chemoradiotherapy. Surgery for NPC is occasionally used, mainly to remove lymph nodes after chemoradiotherapy or to treat NPC that has come back after initial treatment.
How is laryngeal stenosis diagnosed?
A diagnosis of subglottic stenosis can be confirmed based on direct examination of the subglottic area of the windpipe through a procedure known as endoscopy. During this procedure, a physician runs a small tube called an endoscope down the throat.
How do you fix tracheal stenosis?
Common surgical options for tracheal stenosis include:
- Tracheal resection and reconstruction. During a tracheal resection, your surgeon removes the constricted section of your windpipe and rejoins the ends.
- Tracheal laser surgery.
- Tracheal dilation.
- Tracheobronchial airway stent.
What can be done for tracheal stenosis?
Treatment for Tracheal Stenosis
- Laser surgery, which can remove scar tissue, if that is the cause of the stenosis.
- Airway stenting, called tracheobronchial stenting, where a mesh-like tube keeps the airway open.
- Widening of the trachea, or tracheal dilation, where a small balloon or dilator is used to expand the airway.
