Intermediate Cleft Rhinoplasty in Unilateral Cleft Lip Patients: Approaches and Outcomes

Cleft lip and palate is the most common congenital craniofacial abnormality (Jeong, Lee et al. 2012, Yue, Piao et al. 2023). Cleft nasal deformity is the most prominent aesthetic problem in the growing cleft patient after lip repair (Park, Koo et al. 2022). Correction of the residual cleft lip nasal deformity remains a complex and difficult to manage challenge as nasal asymmetry increases with the growth and development of the affected child in addition to the scarring from previous surgeries of the lip and nose (Ayeroff, Volpicelli et al. 2019). The cleft nasal deformity affects all layers of the nose including the bony platform, the inner lining, the cartilaginous infrastructure, and the external skin (Olds and Sykes 2022). The severity of nasal deformity is dependent upon the degree of the original cleft lip abnormality (Gary and Sykes 2016).

There has been a debate for long time regarding the timing of cleft rhinoplasty and there has been a trend to perform it after the age of full maturity. The rationale behind this belief was to avoid interference with nasal growth, however many studies have disproved this traditional idea (Pagan, Sterling et al. 2021) and even in Millard's classic paper, he pointed out that a minor aesthetic correction during childhood is sometimes required (Millard 1964). Cleft rhinoplasties are divided into 3 stages: primary, performed within the first year of life; intermediate, performed prior to completion of facial growth; and definitive, which occurs after skeletal and dental maturity (Ayeroff, Volpicelli et al. 2019).

Intermediate cleft rhinoplasty is defined as any nasal surgery performed between the time of initial cleft lip repair and the time at which the patient reaches facial skeletal maturity (around 15 to 17 years of age in females and in male patients at approximately 16 to 18 years of age) (Gary and Sykes 2016). Intermediate rhinoplasty is indicated in case of functional compromise (nasal obstruction and sleep apnea) as in severe septal deviation and severe alar deformities and in situations of child and parent wishes due to psychological distress from their peers in school age. Some studies have shown that children with orofacial cleft suffer the highest incidence of depression, anxiety, and negative peer relationships around the ages 8 to 10 years (Hoshal, Solis et al. 2020, Olds and Sykes 2022, Park, Koo et al. 2022).

One of the earliest attempts to correct the nasal tip deformity was in 1932 when Gillies and Kilner described the "alar shift" technique, allowing for the advancement of the cleft side columella towards the tip (Wilkie 1969). In 1938, McIndoe was the first surgeon to reposition and fix the cartilage of the cleft side (McIndoe 1938), but Potter in 1954 added the concept of not only repositioning the lower lateral cartilage medially but also the lateral release via an open nasal approach(Potter 1954, Rousso 2015).

In 1964, Millard introduced the concept of additional support using auricular cartilage grafts at 5 years of age with cleft tip revisions (Millard 1964). Tajima and Maruyama in 1977 pointed out that the overhanging alar web is one of the most visible stigmata of cleft noses and this excess skin will result in cartilage malposition and redundancy (Tajima and Maruyama 1977, Nicksic, Pfaff et al. 2018). In 1982, Dibbell described a procedure to address the alar web by rotating and advancing the nostril medially and superiorly in addition to fixation of cleft lower lateral cartilage (Dibbell 1982). Blackwell in 1985 focused on both cartilage reposition and utility of additional support (Blackwell, Parry et al. 1985, Nicksic, Pfaff et al. 2018).
