The nose is an inverted pyramidal structure that consists of an osteocartilaginous framework covered by muscles and skin. It consists of nasal bones and cartilages, including the septal cartilage that separates the nostrils, as well as the upper and lower lateral (alar) cartilages. The septum itself is formed of the columella, the membranous septum and the septum proper. It divides the interior of the nose into right and left nasal cavities. Each cavity communicates with the exterior through a nostril and with the nasopharynx through the posterior nasal aperture or the choana. Each nasal cavity consists of a skin-lined vestibule and a mucosa-lined cavity proper. The lateral wall of the nose features three turbinates (conchae), which are bony projections covered by mucous membrane. The spaces below the turbinates are called meatuses.
Diseases of the external nose include structural deformities, such as saddle or deviated noses. There may also be external congenital tumors such as dermoid cysts, benign tumors, such as rhinophyma, or malignant tumors such as basal cell carcinoma. Diseases of the vestibule include dermatitis (vestibulitis), nasal stenosis or tumors.
Some of these conditions may require a procedure known as rhinoplasty. This is a plastic surgery procedure that is performed to reconstruct the nasal shape, restore the nasal functions or correct the effects of nasal trauma and congenital defects. This can be an open or a closed procedure. Generally, the nasal skin and the soft tissues are separated from the nasal bones and cartilage. After correction is performed, the incisions are sutured and a stent is applied externally or internally to maintain the corrected frame. Sometimes, a cartilage graft may be harvested from the nasal septum, the costal cartilage, or the ear’s external cartilage. A bone graft may also be taken from the hips or the rib cage.
The nasal septum may also be afflicted by fractures or deviation due to trauma or developmental malformations. A septal abscess may occur secondary to a hematoma. Perforation of the septum may thus be traumatic or due to infection. Septoplasty may be needed to treat these septal deformities.
Other conditions that may require surgical treatment of the nose include granulomatous conditions, foreign bodies, nasal polypi, trauma and/or epistaxis.
The paranasal sinuses are air-containing cavities in certain bones of the skull that have openings to the nasal cavity. Inflammation of these cavities can lead to acute or chronic sinusitis. Chronic rhinosinusitis hat does not improve sufficiently with medical treatment may require a procedure known as endoscopic sinus surgery. This procedure aims to open the drainage pathway of the sinuses in order to reduce sinus infections and improve the delivery of externally sprayed medications.
We at Surtex Instruments recognize the characteristic and highly cosmetic nature of nasal surgeries, especially those procedures done for reconstruction. That is why we offered this versatile surgical set with a wide range of uniquely designed instruments to provide optimal surgical technique and improved post-operative results. Our instruments minimize the risk of bleeding and adhesions with their precise and targeted function. We also included many instruments that are designed to guarantee enhanced surgical visualization in order to prevent excessive or inadequate tissue removal. Atraumatic devices are also available to prevent accidental surgical damage to the delicate nasal tissues.
The set includes the delicate dissecting Metzenbaum scissors, which are optimal for cutting delicate tissues and performing blunt dissections. They have dexterous handles and slender shapes, and come with either sharp or atraumatic blunt blades to suit different surgical needs. We also include the compact iris and strabismus scissors that can trim fine tissues, and are available with straight and curved blades. These fine scissors were designed for eye surgeries, and can be used to provide a superior solution in delicate cutting manipulations for ENT surgeries.
The Joseph Mucus Hook is another delicate tool that can be used to dissect and lift flaps of tissues in nasal procedures, such as allowing access to the nasal dorsum during intercartilagenous rhinoplasty. We also include essential tools for bony procedures, such as the Joseph Periosteal Elevator, as well as the Cottle and Sheehan Osteotomes. Another basic instrument is the Vienna Nasal Speculum, which we provide in different sizes to provide convenience and ease with different patients.
