Prospective study of nasal growth in bilateral cleft lip and palate patients after naso-alveolar moulding and primary columella lengthening compared to controls at 5, 10 and 20 years.

INTRODUCTION: A short columella, wide nostrils and a flat nasal tip are common features in patients with bilateral complete cleft lip and palate (BCLP). The objective of this study was to evaluate nasal morphology during growth in patients treated with naso-alveolar moulding (NAM) and primary surgical columella lengthening (PCL) compared with matched non-cleft individuals. STUDY DESIGN: Prospective longitudinal case-control study. PARTICIPANTS AND METHODS: Thirty-four consecutively treated BCLP patients at 5 and 10 years and at the end of growth (19.7 ± 2.0 years) were compared through normalized photogrammetry to a control of 34 age and sex-matched non-cleft individuals. Regression Models for Panel Data assessed how nasal measurements were influenced by surgery, age and gender. RESULTS: Nasal protrusion was equal to non-cleft controls at all ages. Length of the columella was also comparable to controls at 5 and 10 years, but significantly shorter at the end of growth. Inter-alar and nasal tip width and nasolabial angle were significantly wider than controls at all ages: More than 60% of the patients have asked for correction of the nasal width, but no early surgery for columella lengthening was needed. CONCLUSIONS: NAM and PCL have provided a nasal projection close to that of non-cleft individuals until adulthood, while length of the columella was physiological at 5 and 10, but shorter than controls at age 20. Width of the nasal tip and width of the alar bases were significantly wider than the controls and eventually required secondary nasal width correction in over two thirds of the sample.

Photometric Evaluation of Adult Patients With Bilateral Cleft Lip and Palate Treated With Nasoalveolar Molding and Primary Columella Lengthening.

OBJECTIVE: The aim of this study was to assess the nasal shape of young adults with BCLP treated with primary surgical columella lengthening and nasoalveolar molding (NAM). SETTING AND PATIENTS: A group of 28 young adult patients with BCLP (mean age: 19.1±1.4 years) was compared through normalized photogrammetry to a control of 28 age- and sex-matched noncleft young adults. RESULTS: Nasal protrusion and length of the columella were not different from noncleft young adults. On the other hand, nasolabial angle, columellar width, interalar, and nasal tip width were significantly wider than the noncleft controls. Thus, 27% of the patients have requested at this time secondary correction of the excessive nasal width. CONCLUSIONS: Both NAM and primary rhinoplasty in patients with BCLP resulted in a near normal length of the columella and nasal projection until young adulthood. Nevertheless, width of all nasal features was significantly wider than the noncleft population and required secondary nasal correction in one-third of the sample.
