Perforations of the nasal septum (see images below) are often asymptomatic but can lead to a host of distressing symptoms. Large anterior lesions are more likely to affect nasal laminar air flow and be symptomatic. [1] Posterior perforations tend to be less troublesome because humidification of the nasal mucosa and turbinates is maintained. Crusting and epistaxis are the most frequently noted symptoms, but difficulty breathing, pain, rhinorrhea, and postnasal discharge are also common. [2, 3] Small anterior lesions may cause a whistling sound with inspiration. [4]

Approximately 40% of perforations are caused by nasal surgery. External and intranasal trauma, cocaine use, cautery, and chemical inhalants are less frequent etiologies. Infection, lupus erythematosus, Wegener granulomatosis, sarcoidosis, and Osler-Weber-Rendu disease should also be considered. [3]

The initial management of septal perforations is to correct the underlying causative process and encourage natural healing of the lesion. Conservative treatment usually consists of emollients and humidification. [4] (See Septal Perforation - Medical Aspects.) For patients with persistent symptoms, surgical closure or placement of a septal prosthesis are available options. [5, 6] (See Septal Perforation - Surgical Aspects) The techniques and success rates of different closure techniques vary considerably in the literature. [5, 7]

Septal buttons have been commonly used since the 1970s and may be placed in an office setting under local anesthesia. Buttons have been made from acrylic and plastic in the past but are now primarily made of soft silicone (Silastic; see image below). [8] Prefabricated buttons are typically 1-piece units with a flexible hub and pliable discs, which allows them to adapt to the curvatures and irregularities of the septum. [8] Also available are 2-piece units, which tend to have greater ease of insertion. Buttons may be placed as temporary or long-term treatment and do not preclude future surgical closure. Septal buttons are also an option for those in whom surgery may be contraindicated because of age, comorbidities, or underlying pathology.

Prefabricated buttons are excellent options for many septal perforations. Most patients experience improvement or resolution of epistaxis, difficulty breathing, pain, and whistling after placement of nasal septal buttons. [9] However, less than half experience improvement in rhinorrhea and postnasal drainage, [3] and improvement in crusting is variable. [4, 3] Patient intolerance is usually due to local irritation, nasal obstruction, or accumulation of inspissated secretions. Patients who request removal usually do so within 6 months. [2]

Imprecise fit of a nasal septal button may result in increased crusting, obstruction, foreign body sensation, and button dislodgement. Custom-fit button prostheses may provide more comfortable and more reliable fit in some patients.

Several recent studies have examined outcomes when using computed tomography (CT) to custom-fit septal buttons. These techniques are particularly useful for large (>3 cm) perforations in which adjacent soft tissue to secure the button in place is limited. A precise fit is necessary to avoid movement of the button, which can enlarge the perforation and allow the button to be dislodged. [3, 10] Button loss after 5 years was often due to button breakdown, but this exceeds the normal wearout period for Silastic. [3] Additionally, CT-fabricated buttons may improve symptoms to a greater degree than traditional obturators. [10]

Other recently described techniques for generating a custom-fit septal button prosthetics include a handled silicone septal button prosthesis fashioned using an alginate mould and plaster cast, [11] as well as a magnet-based 2-piece button prosthesis. [12] Assets of these buttons include patient comfort and ease of insertion and removal, including the ability for the patient to be able to do so on his or her own.

Relevant Anatomy

The septum is a midline structure that divides the nose into 2 similar halves. The majority of the anterior septum is made up by the quadrangular cartilage. The posterior aspect of the septum is predominantly bony and includes the perpendicular plate of the ethmoid bone superiorly and the vomer inferiorly. The septum also receives bony contributions along its periphery from the maxillary, palatine, frontal, and nasal bones.

Regarding the lateral nasal wall and paranasal sinuses, the superior, middle, and inferior concha form corresponding superior, middle, and inferior meatuses on the lateral nasal wall. The superior meatus is the drainage area for the posterior ethmoid cells and the sphenoid sinus. The middle meatus provides drainage of anterior ethmoid and the maxillary and frontal sinuses. The inferior meatus provides drainage of the nasolacrimal duct.

The internal nasal valve involves the area bounded by upper lateral cartilage, septum, nasal floor, and anterior head of the inferior turbinate. This makes up the narrowest portion of the nasal airway in the leptorrhine nose.

See the list below:

  • Septal button insertion is an elective procedure for symptomatic nasal perforations. [2]



See the list below:

  • Septal deviations are relative contraindications to button placement, since they may cause poor fit against the septum. Absence of the nasal spine also makes for a difficult fit.

  • Additional contraindications include patients with active infections of the nasal cavity, patients who actively use intranasal drugs, or patients who have perforations that are raw or actively bleeding. These patients require workup of an autoimmune, infectious, and malignant process.



See the list below:

  • Anesthetize the nasal mucosa with 1% lidocaine and 1:1000 epinephrine solution on gauze or surgical patties. Alternatively, lidocaine, tetracaine, or cocaine sprays may be used, although cocaine has fallen out of favor because of adverse effects and required regulatory control (see Topical Anesthesia).

  • Some patients, particularly those with very tender nasal passages, may require light sedation.

  • For more information, see Nose Anesthesia.

Tailoring the prosthesis

See the list below:

  • Measure the septal defect along with the upper and lower limit of the septum by inserting a piece of paper in one nostril and laying it long the septum. The size of the perforation can be marked from the other nostril using a marking pen.

  • Trim the flanges of the button to lie equidistant between the perforation and the upper and lower limits of the septum. Smooth the edges of the flanges. See images below.

Technique 1

See the list below:

  • Use the pursestring technique on a 2-0 silk suture (Mersilk, Ethicon, Scotland) to collapse one disk of the silastic obturator 3 mm from the circumference of the disk, with approximately 8-mm spaces between each puncture site. Tie the suture, which results in the disk assuming a concertina shape.

  • Loop the silk suture around the concertina and tie a second knot, which further collapses the disk.

  • Grasp the undeformed disk of the silastic obturator with hemostat and introduce it into one naris with the knotted end of the silk suture placed anteriorly.

  • Advance the collapsed disk through the septal perforation with fiberoptic headlight illumination.

  • Once in situ, cut the silk suture with scissors and remove the suture. This results in the silastic disk returning to its original shape.

  • If any further manipulation of the obturator is necessary, it can be carried out at this point.

  • Postoperative care is with regular steam inhalations for the first 2 postoperative weeks. [13]

Technique 2

See the list below:

  • Make a slit in one of the flanges from the outer edge to the hub.

  • Insert the septal button in one nostril with the slit side toward the septum.

  • Deliver the tip of one of the slit edges through the perforation with a Jobson-Horne probe.

  • Hold the introduced edge from the other side with a hemostat. With the help of another hemostat, rotate the introduced edge in a corkscrew fashion until all of the flange is in the other nostril. Rotate the flange further so that the slit end faces the nasopharynx. [14]

Technique 3

See the list below:

  • Introduce the well-lubricated button into the narrower nasal passage until the anterior-most free margin of the disk, intended to be passed through the perforation, presents itself in the middle of the perforation.

  • Grasp the free margin with a curved hemostat and pull it through the septum toward the contralateral, wider side.

  • Rotating the button along its central axis allows it to optimally adapt to the contours and surfaces of the septum. [8]

Postplacement care

See the list below:

  • The patient should apply normal saline irrigation 3 times daily and nasal cream twice daily.

  • Regular steam inhalations are recommended for 2 weeks.

  • After insertion, there are no strict guidelines on the duration of which a single septal button should remain in place. This is highly dependent on the patient's ability and willingness to perform regular nasal hygiene. Some authors advocate removal and replacement of the button at regular intervals, [11, 12] while others report that the button may remain in place for more than a year. [3]



See the list below:

  • All tissue margins of the perforation must be adequately covered to minimize crusting and bleeding. [2]

  • If the flanges are left too large, they can touch the area where the lower lateral cartilages are inserted into the septum. This can cause pain and discomfort. [14]



See the list below:

  • A few cases of displacement of the prosthesis posteriorly into the nasopharynx have been reported. The prostheses remained there and were retrieved uneventfully. [2]

  • Other long-term complications are increased frequency of epistaxis, increased crusting, intranasal pain, foreign body sensation, and further erosion of the perforation margins with resulting enlargement of the defect. [15]
