Introduction:
Bilateral cleft lip (BCL) repair is a challenge due to anatomic and functional distortions, worse than unilateral cleft. With regard to the nose, BCL can result in certain characteristics, such as a short columella, a flattened and widened tip, and horizontally oriented nostrils. Lip and nose treatment is advocated by some surgeons to achieve a better outcome. One of the techniques used to treat this condition is the one recommended by Victor Spina, in a complex protocol involving more than one surgical procedure and long-term follow-up. The aim of this study is to evaluate the growth of the nose in patients treated using the Spina technique.
Materials And Methods:
This was a retrospective and analytical study of the medical records of patients who were treated using the Spina technique at the Assistance Center for Cleft Lip and Palate (CAIF) at Hospital do Trabalhador in Curitiba, Brazil. Anthropometric measurements of interalar distance and nose tip projection were made from frontal and submental photographs taken at three moments: pre-first surgery, pre-definitive surgery, and late follow-up. Furthermore, other analyzed parameters were: sex, date of birth, age at time of surgery, and late follow-up. With these data, a comparison of nose growth was made between patients with BCL and a population without craniofacial anomalies observed in a study by FARKAS et al (1992). The comparison also took sex and age variables into account.
Results:
Regarding the interalar distance measurements, both sexes showed a widening of the nose before starting treatment. This widening was maintained throughout follow-up. The growth curve, in turn, remained similar among males, with an average growth rate of only 3.2% higher in patients with BCL. Among females, the difference was one of 16.92%. In terms of nasal tip projection, there was an average increase of 1.12 cm (86.15%) in males and 0.69 cm (57.02%) in females.
Conclusion:
It was possible to notice a nasal growth rate in those with BCL similar to the normal pattern and a significant improvement in nasal tip projection in male patients. However, with regard to the data of both sexes, but especially females, the low number of patients jeopardized the significance of the results.
