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 sleeping apnea or breathing disorder 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 Human nose, nasal cavity, dividing the two nostrils. It is Depression (kinesiology), depressed by the depressor septi nasi muscle. Structure The fleshy external end of the nasal s ... toward the opposite side of the nasal cavity.

Nasal Concha
In anatomy, a nasal concha (; : conchae; ; Latin for 'shell'), also called a nasal turbinate or turbinal, is a long, narrow, curled shelf of bone tissue, bone that protrudes into the breathing passage of the nose in humans and various other 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 cavity, 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 surface area of nasal mucosa. As a cilium, ciliated mucous membrane with shallow blood supply, the nasal mucosa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.Ye T, Zhou B. Update on surgical management of adult inferior turbinate hypertrophy. Curr Opin Otolaryngol Head Neck Surg. 2015 Feb;23(1):29-33. 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 anesthes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nasal Septum
The nasal septum () separates the left and right airways of the Human nose, nasal cavity, dividing the two nostrils. It is Depression (kinesiology), depressed by the depressor septi nasi muscle. Structure The fleshy external end of the nasal septum is called the Human nose#Cartilages, 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: * Maxillary bone (the crest) * Perpendicular plate of ethmoid bone * Septal nasal cartilage (ie, quandrangular cartilage) * Vomer bone 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 h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
