Analysis of nasal and labial deformities in cleft lip, alveolus and palate patients by a new rating scale: preliminary report
Section snippets
INTRODUCTION
Nasal deformities have always been a fundamental problem in the treatment of cleft lip, alveolus and palate patients. Some authors (McComb, 1985; Pigott, 1985; Trott and Mohan, 1993a,b) prefer primary, i.e. early correction of these deformities during the initial operation (cheilo-rhinoplasty), whilst others (Delaire, 1978; Cronin and Denkler, 1988; Pellerin and Louis, 1993) concerned with growth retardation reserve these corrections for a later date (secondary rhinoplasty). In our opinion, the
MATERIAL AND METHODS
Application of this method helps to obtain the following data for every patient:
- •
initial assessment of the severity before operation;
- •
postoperative assessment at different stages of treatment and reassessment after each operation.
Classification of the severity of the cleft before surgery is based on the principle of dividing the cleft into thirds, i.e. nose and lip, hard palate as well as soft palate, similar to the classification of the American Cleft Palate Association. The rating system is
SURGICAL METHODS AND PATIENTS
Fifty patients with cleft lip, alveolus and palate who underwent different surgical procedures were analysed (Table 4).
- 1.
Primary cheiloplasty: a modified Millard primary cheiloplasty was performed on 29 children aged from 5 days to 18 months (mostly at age of 3 months). Thirteen of those were unilateral clefts of lip, alveolus and palate scored as “moderate” and 16 were bilateral CLAP, 11 of them classified as “very severe”, 4 “severe” and 1 “mild”. A modification of Millard's procedure was used
RESULTS
All results were analysed at least 6 months postoperatively by clinical examination.
In the 13 primary unilateral cheiloplasties: 10 “excellent”, 2 “good” and 1 “satisfactory” results were obtained. The most common deformities after primary cheiloplasty were the defect of the soft tissue triangle (10 out of 13 cases; Fig. 4) and insufficient wrapping of the ala (4 out of 13 cases).
In the 16 primary bilateral cheiloplasties: 7 “excellent”, 4 “very good”, 4 “satisfactory” and 1 “poor” result were
DISCUSSION
From the results presented in the pictures it is obvious, that the defect of the soft tissue triangle of the nose was the most common problem found pre- and postoperatively in both uni- and bilateral clefts. The lack of insertion of the transverse nasal muscle to the anterior nasal spine leads to dislocation of the medial alar cartilages and insertion into the skin, which takes place in utero. Correction of this deformity might be achieved following primary cheiloplasty, but our observations
CONCLUSION
Detailed analysis of the preoperative state compared with the postoperative results using the described scoring system has its benefits. It enables comparisons between the results obtained in cases of equally severe clefts, i.e. a more precise assessment of the therapeutic benefits. It makes it possible to define every single defect of any nasal deformity, and to determine its frequency and aetiology; it will reveal errors and show whether the aim of the operation has been achieved.

Perceptions and satisfaction of aesthetic outcome following secondary cleft rhinoplasty: Evaluation by patients versus health professionals

Although aesthetic and functional outcomes following cleft rhinoplasty have been reported previously (Anastassov and Chipkov, 2003; Gurley et al., 2001; Kane et al., 2000; Salyer, 1986; Sandor and Ylikontiola, 2006), research to determine patient satisfaction is limited to date. In this study, we aimed to evaluate whether cleft rhinoplasty was associated with patient satisfaction from an aesthetic and functional perspective.
