Septoplastie

Septoplasty [ˈsɛp.toˌplæ.sti] (Etymology: L, saeptum, septum; Gk, πλάσσειν plassein – to shape), or alternatively submucous septal resection and septal reconstruction, is a corrective surgical procedure done to straighten a deviated nasal septum – the nasal septum being the partition between the two nasal cavities. Ideally, the septum should run down the center of the nose. When it deviates into one of the cavities, it narrows that cavity and impedes airflow. Deviated nasal septum or “crooked” internal nose can occur at childbirth or as the result of an injury or other trauma. If the wall that functions as a separator of both sides of the nose is tilted towards one side at a degree greater than 50%, it might cause difficulty breathing. Often the inferior turbinate on the opposite side enlarges, which is termed compensatory hypertrophy. Deviations of the septum can lead to nasal obstruction. Most surgeries are completed in 60 minutes or less, while the recovery time could be up to several weeks. Put simply, septoplasty is a surgery that helps repair the passageways in the nose making it easier to breathe. This surgery is usually performed on patients with a deviated septum, recurrent rhinitis, or sinus issues. The procedure usually involves a judicious excision/realignment of a portion of the bone and/or cartilage in the nasal cavity. Under general or local anesthesia, the surgeon works through the nostrils, making an incision in the lining of the septum to reach the cartilage/bone targeted in the operation. This may be performed using an endoscope or with open techniques. Sufficient cartilage and bone is preserved for structural support. After the septum is straightened, it may then be stabilized temporarily with small plastic tubes, splints, or sutures internally. Skin grafts can be placed internally to support the internal structures. Apart from in patients with deviated nasal septum causing airway obstruction leading to difficulty with breathing, recurrent rhinitis, or sinusitis, septoplasty is done as an approach to hypophysectomy.

Déviation de la cloison nasale

La déviation de la cloison nasale est une déformation de la paroi intérieure du nez, vers la droite ou vers la gauche. Elle peut concerner le cartilage ou les os du nez, ou les deux à la fois. La cloison nasale est aussi appelé septum nasal. Les causes peuvent être : une malformation de naissance, ou apparaissant lors de la croissance un traumatisme du nez à la suite d'un impact ou d'un choc par exemple Il peut survenir des difficultés respiratoire, une apnée du sommeil, des ronflements, des troubles du sommeil.

Human nose

The human nose is the most protruding part of the face. It bears the nostrils and is the first organ of the respiratory system. It is also the principal organ in the olfactory system. The shape of the nose is determined by the nasal bones and the nasal cartilages, including the nasal septum which separates the nostrils and divides the nasal cavity into two. On average, the nose of a male is larger than that of a female. The nose has an important function in breathing.

Cornet nasal

Les cornets nasaux sont 3 paires de lames osseuses enroulées participant aux fosses nasales chez les vertébrés. Ils sont formés par deux os, le cornet nasal inférieur et l'os ethmoïde. Leur structure tridimensionnelle et la muqueuse spécialisée des cornets sont responsable de leurs fonctions : respiratoire (filtration, humidification et chauffage de l'air inhalé avant qu'il n'atteigne les poumons), immunologique (piège des agents pathogènes) et olfactive (flux d'air dirigé vers les récepteurs du nerf olfactif).
