A nasal septum perforation is a medical condition in which the nasal septum, the bony/cartilaginous wall dividing the nasal cavities, develops a hole or fissure. [1]This may be brought on directly, as in the case of nasal piercings, or indirectly, as by long-term topical drug application, including nasal administration of ethylphenidate, methamphetamine, cocaine, crushed prescription pills, or ...
It supports the olfactory bulb, and is perforated by olfactory foramina for the passage of the olfactory nerves to the roof of the nasal cavity to convey smell to the brain. The foramina at the medial part of the groove allow the passage of the nerves to the upper part of the nasal septum while the foramina at the lateral part transmit the ...
Nasal septum deviation is the most common cause of nasal obstruction. [7] A history of trauma to the nose is often present including trauma from the process of birth or microfractures. [ 7 ] A medical professional, such as an otorhinolaryngologist (ears, nose, and throat doctor), typically makes the diagnosis after taking a thorough history ...
The septum generally stays in the midline until about the age of seven, at which point it will frequently deviate to the right. An operation to straighten the nasal septum is known as a septoplasty. A perforated nasal septum can be caused by an ulcer, trauma due to an inserted object, long-term exposure to welding fumes, [6] or cocaine use ...
The medial crura are attached to the septal cartilage, forming fleshy parts at the front of the nostrils on each side of the septum, called the medial crural footpods. The medial crura meet at the midline below the end of the septum to form the columella [11] and lobule. The lobule contains the tip of the nose and its base contains the nostrils ...
In most fungi, hyphae are divided into cells by internal cross-walls called "septa" (singular septum). Septa are usually perforated by pores large enough for ribosomes , mitochondria , and sometimes nuclei to flow between cells.
Septal perforation and dermatitis of nasal vestibule can occur. The nose may show a saddle-nose deformity. Atrophic rhinitis is also associated with similar atrophic changes in the pharynx or larynx, producing symptoms pertaining to these structures. Hearing impairment can occur due to Eustachian tube blockage causing middle ear effusion.
Septoplasty (Latin: saeptum, "septum" + Ancient Greek: πλάσσειν, romanized: plassein, "to shape"), or alternatively submucous septal resection and septal reconstruction, [1] is a corrective surgical procedure done to straighten a deviated nasal septum – the nasal septum being the partition between the two nasal cavities.
