Submucous resection for deviated nasal septum: a critical appraisal.

Submucous resection (SMR) for the deviated nasal septum had been criticised to have a higher complication rate and less patient satisfaction than septoplasty. Seventy-five patients who underwent SMR were studied and followed up at 6 months to 56 months post-operatively. The rates of short and long term complications were relatively low: septal haematoma 1.3%, nasal infection 1.3%, epistaxis 2.6%, external nasal deformity 9.3% and septal perforation 2.7%. While most patients achieved short term relief of nasal obstruction (93.4%), about 30% had persistent/recurrent nasal obstruction on long term follow-up. Similar rates had been quoted for the operation of septoplasty. We postulated that this was due to unfavourable airflow patterns as a result of minor residual septal deviation. Some patients had associated pre-operative symptoms of snoring (57.3%), headache (48.0%), rhinorrhoea (38.7%), sneezing (30.7%), hyposmia (30.7%) and epistaxis (21.3%). Frequencies of cure/improvement of these symptoms after SMR were 34.9%, 33.3%, 24.1%, 30.4%, 60.9% and 43.8% respectively. The overall post-operative long term (average 23.5 months) satisfaction rate was almost 70%. SMR, being relatively easy to perform, and having similar complication and patient satisfaction rates as septoplasty, should be retained in the surgical armamentarium for the deviated nasal septum.
