A Single Institution 19 Year Comparison of Furlow and Straight Line Palatoplasty Techniques in Bilateral Cleft Lip and Palate

Abstract

Objective:

This study aims to compare patients’ speech correcting surgery and fistula rates between the Furlow and Straight Line (SLR) palatoplasty techniques when combined with greater palatine flaps for complete bilateral cleft lip and palate (BCLP) repair.

Design:

This was a single-center IRB approved retrospective cohort study.

Setting:

This study took place at an urban tertiary academic center.

Patients, Participants:

All patients with BCLP anomalies that underwent repair between January 2003 and August 2022 were included. Patients with index operations at an outside institution or incomplete medical charting were excluded.

Interventions:

A total of 1552 patients underwent palatoplasty during the study period. Of these, 192 (12.4%) met inclusion criteria with a diagnosis of BCLP.

Main Outcome Measures:

Primary outcomes of this study included rate of fistula and incidence of speech correcting surgery. Secondary outcomes included rate of surgical fistula repair.

Results:

One hundred patients underwent SLR (52.1%) and 92 Furlow repair (47.9%). There was no significant difference in fistula rates between the SLR and Furlow repair cohorts (20.7% vs. 15.0%; p = 0.403). However, SLR was associated with lower rates of speech correcting surgery when compared to the Furlow repair (12.5% vs. 29.6%; p = 0.011).

Conclusions:

This study compares the effect of Furlow and SLR on speech outcomes and fistula rates in patients with BCLP. Our findings suggest that SLR resulted in an almost three times lower rate of velopharyngeal dysfunction requiring surgical intervention in patients with BCLP, while fistula rates remained similar.
