[Nasal septum repair-plasty with pedicled flap technique in 126 patients--an analysis].

BACKGROUND

The surgical closure of a nasal septal perforation is considered to be one of the most difficult procedures in nasal surgery with a relatively poor success rate. After a new surgical concept ("bipedicled-flap technique") was developed, a follow-up study was done in order to find out whether surgical results can be improved by means of this new method.

PATIENTS AND METHOD

From 1988-1995 the bipedicled-flap technique was applied in 126 patients with nasal septal perforations (82 males, 44 females). In all patients the closure of the septal perforation was performed with an endonasal bilateral bipedicled-flap plasty and reconstruction of the cartilaginous defect with an autogenous cartilage graft from either the rib, the auricle, or from remnants of the septal cartilage. Postoperative results were evaluated in all patients. The follow-up period varied from a minimum of six months to a maximum of over seven years.

RESULTS

The age peak was found in the third decade of life (females) and fifth decade (males), respectively. Most frequent preoperative symptoms were difficult nasal breathing, crusting and recurrent epistaxis. 65.8% of septal perforations were of iatrogenic origin. In 32 patients, the aetlology remained unknown. Six patients used silicone obturators preoperatively without getting any relief from complaints. In nine patients, surgical repair of the septal perforation had been attempted previously at another hospital. With the bipedicled-flap technique, primary closure was achieved in 118 patients (= 93.6%); revision surgery (same technique) was successfully performed in 2 patients, increasing the final success rate to 95.2%. Complications were rare and could always be managed easily.

CONCLUSIONS

At present, the bipedicled-flap technique appears to be the most successful method for surgical repair of nasal septal perforations. The underlying principles responsible for the good success rate are: (1) the bilateral closure of the mucosal defects; and (2) the additional reconstruction of the cartilaginous septal defect with an autogenous cartilage graft only.
