The absolute and relative effects of presurgical nasoalveolar moulding in bilateral cleft lip and palate patients compared with nasal growth in healthy newborns

An evaluation of the customized nasal clip protocol for bilateral cleft lip and palate presurgical infant orthopaedics

OBJECTIVES

Nasoalveolar moulding (NAM) has resulted in profound outcomes in the treatment of bilateral cleft lip and palate patients, including non-surgical columellar lengthening and nasal moulding. We examine an innovative alternative that is less invasive, yet provides similar results. In this study, we describe a novel approach using the Customized Nasal Clip Protocol (CNCP™) and compare the treatment outcomes of a small cohort of infants with bilateral cleft lip ± palate with published results of the Grayson nasoalveolar moulding protocol.

MATERIALS AND METHODS

A cohort of six bilateral-cleft-affected patients was evaluated for this study. Standardized frontal and worm's eye view photographs were obtained, and clinical measurements were utilized to garner columellar length measurements and nostril height comparisons. The initial and post-surgical results were statistically compared with a student's t-test (p < .05). Inclusion and exclusion criteria were applied to the cohort, which will be described.

RESULTS

The resulting columellar length and nostril height increases of the CNCP™ group were comparable to a published cohort of subjects that have undergone nasoalveolar moulding. The nasal changes were found to be significant with a p-value <.01. The CNCP™ cohort also had fewer clinic visits, no complications that led to complete pauses of active treatment, and the benefit of receiving comprehensive treatment that was initiated at their first clinical presentation, in comparison to traditional NAM patients.

CONCLUSION

The increase of columellar length and nostril height that resulted from utilizing the CNCP™ in bilateral cleft patients met the treatment goals of presurgical infant orthopaedics, with results on par with published results of NAM. These results, paired with the reduction in patient, family, and provider burden, further support the continued use and development of the CNCP™ for appropriate patient populations.

Surgical Nasoalveolar Molding: A Rational Treatment for Bilateral Cleft Lip Nose and Systematic Review

Background:

The purpose of this study was to evaluate the surgical outcome after using primary surgery to address bilateral cleft lip nose and palate deformities. In addition, the authors performed a systematic review to evaluate the effects of the nasoalveolar molding on non-syndromic bilateral cleft lip and palate.

Methods:

A prospective cohort study on a surgeon’s surgical outcome of 25 consecutively performed primary bilateral cleft lip nasal deformity repairs was conducted and a systematic review of the literature for studies published until December 2019 was done to evaluate the effect of presurgical NAM on nasolabial aesthetics and alveolar gap.

Results:

Since 2014, 25 consecutive patients with complete bilateral cleft have undergone primary anatomical repair of the cleft nasal deformity using primary cheilorhinoplasty. The average columella length was 4.3 ± 1.3 mm. The average ratio of the columella height to nasal height was 0.48 mm 1 year postoperatively and 0.52 mm 5 years postoperatively. Statistically significant differences have been observed between the pre and postoperative alveolar and palatal gaps after using primary cheiloplasty or bilateral lip adhesion. After systematic literature searching, 14 identified studies were qualified for the final analysis, which included 433 patients. The overall study quality according to Oxford CEBM and GRADE scale was low.

Conclusions:

The results of this study suggest that the proposed primary cheilorhinoplasty is a good alternative to improve nose appearance and alveolar gap in patients with primary bilateral cleft lip nose and palate deformity. Based on the available scientific evidence, definitive conclusions about the effectiveness of presurgical Naso Alveolar Molding on nasolabial aesthetics cannot be drawn. Quality of the included articles were too low to make a conclusion.
