Which technique for which hole?

Four pieces of information guide the choice of a closure technique: the size of the hole, its position, whether it is a revision, and how much cartilage is left around it. Answer the four questions to see what the reference textbook's algorithm proposes, and what to ask your surgeon.

In brief

1

Under 2 cm, first closure: the bipedicled advancement flap is the reference, with two alternatives.

2

For a revision, the position of the hole relative to the incisive canal guides the choice of flap.

3

The cartilage and bone left around the hole decide what is possible: have them checked on CT and in clinic.

The 4-question guide

Answer with the information from your ENT or your CT scan. Nothing is saved or sent. Tap an answer again to clear it.

1. How big is the hole?
Its largest diameter, measured by your ENT or on CT.
2. Where is it relative to the incisive canal?
The incisive canal is a small bony canal at the front of the nasal floor, visible on CT. The hole is called anterior if its back edge lies in front of this canal.
3. Is this a first closure?
Or a revision, after a closure that failed.
4. Is there cartilage or bone left around the hole?
This is what allows the mucosa to be lifted. It shows on CT and is checked in clinic, by palpation under the endoscope.

The technique matters less than you think

The textbook's meta-analysis pools 105 studies and 2,404 patients. The major families of techniques reach very similar closure rates.

Endoscopic and open approaches are on a par; the choice depends mostly on the surgeon's training. Adding a graft between the mucosal layers does not clearly change the result (91% with, 93% without), and the type of graft does not predict it.

What really weighs: smoking, a previous septoplasty or closure attempt, cocaine. And probably the team's experience.

If your turbinates have already been reduced

"Empty nose" point
  • The lateral wall flap is contraindicated after turbinate surgery for atrophic rhinitis.
  • Many flaps take mucosa from the floor or the inferior meatus, which then heals bare.
  • These flaps should be discussed with the surgeon if your turbinates have already been reduced.

The textbook says very little about empty nose syndrome: ask explicitly. Source: Yuen-Ato, Rojas-Lechuga, Alobid, ch. 13.

Note before the consultation

Questions to ask my surgeon

  1. Do you measure the height of the hole and its position relative to the incisive canal?
  2. Is there cartilage or bone left around the hole?
  3. Which technique do you propose? Which mucosa do you take, and where will bare areas remain?
  4. Do you add a graft between the two mucosal layers? Of what type?
  5. Do you close both sides?
  6. How many perforation closures do you perform per year, and with what rate at 1 year?
  7. How do you protect my turbinates if I have empty nose syndrome?

Frequently asked questions

What is the best technique?

None stands out in the data: 92% closure for pedicled flaps, 91% for mucosal sliding as for grafts without a flap. The right technique is the one that suits your hole, in the hands of a team that performs it often.

What is the incisive canal?

A small bony canal at the front of the nasal floor, visible on CT. It serves as a landmark: a perforation is called anterior if its back edge lies in front of this canal, whatever its size.

Is a graft between the two mucosal layers needed?

The data show no clear difference (91% with, 93% without), and the type of graft does not predict the result. Several authors still find it useful, especially connective tissue. When used, it must be fully covered by vascularised mucosa.
