"Primary anterior septoplasty in a cleft repair improves deviation of the anterior septum but not that of the posterior bone structure.".

Background: Evaluation of the result on the nasal septum (NS) of primary anterior septoplasty in cleft surgery is lacking. The deviation in patients with a cleft between those with (S+) and without (S-) primary anterior septoplasty during a cleft lip repair was compared.

Methods: This was a retrospective, descriptive, single-center study. The NS was evaluated on computed tomography scans obtained pre-operatively from patients who underwent surgery for an alveolar cleft defect. Deviation of the NS was evaluated based on the following parameters: 3D configuration of the NS; anterior, middle, or posterior severity of the NS deviation; location of the most projected point; and severity index.

Results: The mean age of evaluation was 6.18 years. A total of 44 (S-) and 48 (S+) patients were included. The NS was less prominent in the (S+) than in (S-) group, 6.25% vs 25%. respectively. In the anterior part, the NS was normal in 79% (S+) and 1% (S-) of the patients. In the posterior region, the prominent deviation rate was approximately 7% in both groups. The greatest deviation point location was identical in both groups. The severity index was higher in the (S-) than in (S+) group, except in the middle part of the NS.

Conclusions: Primary anterior septoplasty corrects only the anterior aspect of the NS in most children with CL and CLP. However, the posterior aspect of the NS remains deviated. A posterior deviation is likely to lead to nasal obstruction therefore regular monitoring is required all along the growing period.
