Concha Bullosa
A concha bullosa is a pneumatized (air-filled) cavity within a nasal concha, also known as a ''turbinate''. Bullosa refers to the air-filled cavity within the turbinate. It is a normal anatomic variant seen in up to half the population. Occasionally, a large concha bullosa may cause it to bulge sufficiently to obstruct the opening of an adjacent sinus, possibly leading to recurrent sinusitis and various head pains related to areas innervated by the trigeminal nerve. In such a case the turbinate can be reduced in size by endoscopic nasal surgery (turbinectomy). The presence of a concha bullosa is often associated with deviation of the nasal septum The nasal septum () separates the left and right airways of the nasal cavity, dividing the two nostrils. It is depressed by the depressor septi nasi muscle. Structure The fleshy external end of the nasal septum is called the columella or col ... toward the opposite side of the nasal cavity.

Nasal Concha
In anatomy, a nasal concha (), plural conchae (), also called a nasal turbinate or turbinal, is a long, narrow, curled shelf of bone that protrudes into the breathing passage of the nose in humans and various animals. The conchae are shaped like an elongated seashell, which gave them their name (Latin ''concha'' from Greek ''κόγχη''). A concha is any of the scrolled spongy bones of the nasal passages in vertebrates.''Anatomy of the Human Body'' Gray, Henry (1918) The Nasal Cavity. In humans, the conchae divide the nasal airway into four groove-like air passages, and are responsible for forcing inhaled air to flow in a steady, regular pattern around the largest possible of [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sinusitis
Sinusitis, also known as rhinosinusitis, is inflammation of the mucous membranes that line the sinuses resulting in symptoms that may include thick nasal mucus, a plugged nose, and facial pain. Other signs and symptoms may include fever, headaches, a poor sense of smell, sore throat, a feeling that phlegm is oozing out from the back of the nose to the throat along with a necessity to clear the throat frequently and frequent attacks of cough. Generally sinusitis starts off as a common viral infection like common cold. This infection generally subsides within 5 to 7 days. During this time the nasal structures can swell and facilitate the stagnation of fluids in sinuses that leads to acute sinusitis which lasts from 6th day of the infection to 15th day. From the 15th day to 45th day of the infection comes the subacute stage followed by chronic stage. Whenever a chronic stage patient's immunity takes a hit the infection moves to "acute on sinusitis" stage and moves back to ...

Turbinectomy
A turbinectomy or turbinoplasty (preserving the mucosal layer) is a surgical procedure, that removes tissue, and sometimes bone, of the turbinates in the nasal passage, particularly the inferior nasal concha. The procedure is usually performed to relieve nasal obstructions. In most cases, turbinate hypertrophy is accompanied by some septum deviation, so the surgery is done along with septoplasty. Indications A turbinectomy is usually performed to resolve turbinate hypertrophy, where the turbinates are swollen and enlarged. Common causes of this condition are allergies, environmental irritants, or a deviated septum. Procedure Traditional methods There are many different techniques used in a turbinectomy, including electrocautery, cryotherapy (cryoturbinectomy), laser vaporization, and turbinoplasty. These require general anesthesia. Radiofrequency ablation The use of radiofrequency ablation has shown to be a safer alternative, being performed as an outpatient procedu ...

Nasal Septum
The nasal septum () separates the left and right airways of the nasal cavity, dividing the two nostrils. It is depressed by the depressor septi nasi muscle. Structure The fleshy external end of the nasal septum is called the columella or columella nasi, and is made up of cartilage and soft tissue. The nasal septum contains bone and hyaline cartilage. It is normally about 2 mm thick. The nasal septum is composed of four structures: * Perpendicular plate of ethmoid bone * Vomer bone * Septal nasal cartilage * Maxillary bone (the crest) The lowest part of the septum is a narrow strip of bone that projects from the maxilla and the palatine bones, and is the length of the septum. This strip of bone is called the maxillary crest; it articulates in front with the septal nasal cartilage, and at the back with the vomer. The maxillary crest is described in the anatomy of the nasal septum as having a maxillary component and a palatine component. Development At an early peri ...
