5Definition/Purpose of Procedure Excision and resection of the septum to correct any deviation as a result of injury or a congenital nasal deformity; to improve the functioning capabilities of the nose—to improve breathingThe cartilaginous or osseous portions of the septum that lie between the flaps of the mucous membrane and the perichondrium are straightened; cartilage & bony spurs may block the meatus and compress the middle turbinate on that side, resulting in an obstruction of the sinus openingOther names: nasal septal reconstruction (NSR), submucous resection of the septum (SMR)Alexander: Objective: to establish an adequate partition between left and right nasal cavities, thereby producing a clear airway through both the internal and external cavities of the nose.The name SMR tells us that the mucous membrane lining the nasal cavity will be incised, and the underlying perichondrium or periosteum lifted. Then the structures underneath the mucous membrane will be removed to help restore normal breathing.
6Relevant A & P: External nose—lateral and anterior views STST p. 601
7Relevant A & P: Nasal Septum & Related Structures The nasal cavity is divided into 2 chambers by the nasal septum (above). Anteriorly, the septum is cartilaginous, posteriorly, the septum has bony attachments to the ethmoid and vomer bones. The septal cartilage is also known as the quadrilateral cartilage.Each nasal cavity, or fossa, has a series of 4 bony projections called conchae or turbinates. The chonchae are osseous ridges on the lateral walls of the cavity. They are named by location: supreme, superior, middle, & inferior. The oriface of each eustachian tube enters the nasal cavity posterior to the turbinates.
8Relevant A & P: Blood Supply to Nose STST SEE p Shows that branches of the internal and external carotid arteries provide blood supply to the nose.. The main source is the internal mammary artery, which is one of the terminal divisions of the external carotid.A common site for epistaxis is Kiesselbach’s plexus—at the terminal end of the anterior ethmoid artery and the corresponding veins in the anterior septum..
9PathophysiologyAlexander: Septal deviations tend to cause sinus disease and nasal polyps.Allrefer.com:The main indications for nasal surgery are:nasal airway obstructionseptal spur headacheuncontrollable nosebleedsnasal septal deformity in the presence of other intranasal surgeryNasal airway obstruction is usually the result of a septal deformity that causes breathing by mouth, sleep apnea, or recurrent nasal infections that are slow to respond to antibiotics. A septal spur headache is defined as a headache secondary to pressure from the nasal septum on the linings in side the nose (septal impaction) and relieved by topical (applied to a localized area of the skin) anesthesia on the septal impaction. Other intranasal surgery indicating septoplasty includes polypectomy (removal of a polyp), ethmoidectomy (operation on the ethmoid bone at the superior part of the nasal cavity), turbinate surgery (operation on the concha nasalis), and tumor removal.Also done in conjunction—surgeon may perform a Turbinectomy:Removal of portions of the inferior and middle turbinates to increase aeration and drainage and to relieve pressure against the floor of the nose.
10Diagnostics Exams Preoperative Testing Rhinoscopy: Direct vision STST p. 605: Will use special illumination equipment—headlamp and nasal speculum
11Surgical Intervention: Special Considerations Patient FactorsPt should know before hand that he/she will be mouthing-breathing postoperatively because of postop nasal packing 1-3 days post-opPt should understand that application of ice will reduce swelling and brusing around eyes and nose postopertivelyIf under local, keep noise to a minimum in the ORAdvise pt to remain still and to expect vibrations caused by bone remodeling (mallet and osteotome)Be aware of drapes on face—minimize claustrophobia and facilitate respirationThis is a clean case—use best techniqueRoom Set-upSurgeon may prefer bed turned to 90 degrees of anesthesia for greater access to headSeparate Mayo set up for surgeon to use for preop anesthetic and cocaine nasal packing
12Surgical Intervention: Anesthesia Method: Local, Regional, GeneralLocal with IV sedation and analgesia is typicalGeneral for the very apprehensiveEquipmentNote that anesthesia should ensure pt eye protection using ointment & protective eyewear
13Surgical Intervention: Positioning Position during procedureSupine, head tilted backHOB may be slightly elevated (reverse Trendelenburg)Pt comfort: flex hip and knees w/OR table settings or pillow under knees/lower legsTuck arms to sides; use protective arm sleds and paddingSupplies and equipmentFoam headrest or donut for head stabilizationSpecial considerations: high risk areasUlnar nerves where arms are tuckedHead is raised to reduce bleeding and prevent edemaPillow under knees alleviates lumbar strain.
14Surgical Intervention: Skin Prep Method of hair removal: N/AAnatomic perimeters: face—avoid solution from getting in or near eyes and ears; do not prep interior of noseSolution options: may use betadine paint –avoid hibiclens at mucous membranes; may not ask for prep
15Surgical Intervention: Draping/Incision Types of drapesUsually turban-type head wrap or 3 towels arranged triangularlyOrder of drapingRemove paper strips from disposable drapes with adhesive edgesPlace bar drape across pt forehead & allow remainder of drape to fall toward floor covering the head of OR tablePlace U-drape on upper lip. Bring edges of U lateral to the nose and eyes. Extend the rest to cover pt’s bodySpecial considerationsState/Describe incisionIntranasal incision into mucous membrane and perichondrium
16Surgical Intervention: Supplies GeneralHead and Neck (ENT) pack; suction tubing, ESU pencil, raytex, 4 pk hand towels, needle magnet, syringe for cleaning suctionSpecificSuture & Blades: Fine (4-0) absorbable (atraumatic); # 15 x 2Medications on Mayo stand: Lidocaine w/epi 1: 100, 00 usually for injection to nares (also have available on back table); Cocaine (1 sm bottle) for nasal packingCatheters & DrainsPacking & Nasal splints: may use Iodoform or Vaseline or Xeroform gauze packing in addition to plastic nasal splint material (plastic or Silastic) post-op. May be manufacturer’s kit.2x2’s and ¼” hypoallergenic tape
17Surgical Intervention: Instruments GeneralSpecific (see following slides)
18Surgical Intervention: Instruments Nasal InstrumentationYankauer Suction Tip# 3 scalpel handle# 7 scalpel handleCurved-sharp point Plastic surgery scissors
19Surgical Intervention: Instruments Joseph nasal scissors—straight and curvedMetzenbaum scissors (delicate pattern 5 ½ in)Metzenbaum scissors (delicate pattern 7 in)Adson tissue forceps (with teeth/angled)
27Surgical Intervention: Procedure Steps An incision is made internally on one side of the nasal septum. After the mucous membrane is elevated away from the bone, obstructive parts of bone and cartilage are removed, and plastic surgery is performed as necessary. Then the mucous membrane is returned to its original position.Overview: (allrefer.com)An incision is made internally on one side of the nasal septum. Afterwards, the mucous membrane is elevated away from the cartilage and bone, obstructive parts are removed, and plastic surgery is performed as necessary. Then the mucous membrane is returned to its original position. The tissues covering the septum are maintained in the midline by either sutures or packing.
28Surgical Intervention: Procedure Steps Before the surgical scrub, the surgeon will place cocaine-soaked cottonoids into the nares and inject of local anesthetic (usually lidocaine w/epinephrine)* STSR will set up medicine cup, cottonoids, speculum and bayonet forceps on Mayo for surgeon to pack the nose. The circulator will pour the 4% Cocaine and count cottonoids with the STSR and ensure 27 g.local/needle and Luer-lock syringe is availableSurgeon opens nostril w/speculum, incises the mucoperichondrium w/nasal knife, then deepens the incision w/ fine, sharp dissecting scissors.* Provide surgeon w/nasal speculum of appropriate size. Have cottle clamp available to aid incision process. Use # 15 blade on a #7 handle for incision.
29Surgical Intervention: Procedure Steps For retraction, small skin hooks are placedSurgeon elevates the mucoperichondrium from the septal cartilage using a fine (Freer) elevator, & removes any spurs from the septum or nasal bone w/nasal/septum cutting forceps (punch, ronguer, or cutting forceps)* Provide suction as needed. Most likely, the sharp end of the Freer elevator will be used.* Have chisel (or gouge) & mallet available. STSR may be asked to “tap” the chisel held by the surgeon w/ the mallet. This may not be considered within your scope of practice at your facility—find out before hand.* Have bayonet or Takahashi forceps available to extract tissue remnants. Surgeon may reinsert bone and cartilage to refashion the nasal cavity and to strengthen weakened areas (keep moist w/NS on the back table in a small basin)
30Surgical Intervention: Procedure Steps With the mucochondrium fully elevated, the surgeon removes the septal cartilage w/ a nasal forcep. Examines septal tissue & reshapes as needed w/scissors, rasp, or special bone crusher that flattens cartilage.Surgeon replaces the septal cartilage within the nose.Hemostasis is achieved.* Have suction, hemostatic agents, &/or ESU pencil available.Surgeon closes the incision w/suture &/or hold cartilage in place with packing material (petroleum gauze & nasal splints)*Have splint material ready—surgeon may cut to fit the patient using Heavy scissors. It may be sutured in place.
31Surgical Intervention: Procedure Steps Dressing may include external splints and “mustache dressing”Secretions are removed from pharynx to reduce risk of aspiration * provide Wieder retractor and Yankauer tip.For TurbinectomyTurbinectomy is performed to remove a hypertrophic turbinate, usually the inferior turbinates. What is the cause of hypertrophied turbinates? They are often a result of chronic rhinitis. Recurrent inflammations cause the structure to lose its elasticity.A submucosal approach is used. The nasal mucosa along the edge of the affected turbinate is incised. All or some of the bones of the turbinate are removed. The mucosa is repositioned and held in place w/intranasal packing.
32Counts Initial: Sponges and sharps (raytex and cottonoids) First closingFinal closingSpongesSharps
33Dressing, Casting, Immobilizers, Etc. Types & sizesMustache dressing –have 2x2’s available and ¼” silk or micropore tapeExternal Splint of surgeon’s preference (eg. Denver splint kit)Type of tape or method of securing—least irritating to skinHave ice pack available (can make using 2 gloves tied together w/crushed ice)
