Cleft Lip Repair: Through the Looking Glass

Utility of J-Shaped Scar Tissue-Based Flap for Secondary Bilateral Cleft Lip Repair: A One-Stage Procedure with Successful Outcomes on Correction of Vermilion Border, Volume Deficiency of Lip, and Muscular Function

This study aimed to evaluate the utility of J: -shaped scar-tissue-based flap as a new technique in secondary bilateral cleft lip reconstruction in patients with challenging secondary deformities. A total of 52 patients, comprising 38 males and 14 females with a mean age of 21.0 years (range: 16-42 years), who underwent secondary bilateral cleft lip repair operation via the J: -shaped scar tissue flap technique in our clinic between 2014 and 2019 were included. Postoperatively, patients were followed up for an average of 2 years (range, 6 months to 5 years) to assess the outcomes regarding vermilion border, philtrum symmetry, function of the orbicularis muscle, and lip volumetric symmetry, based on the Global Aesthetic Improvement Scale (GAIS), patient-reported outcomes, and independent plastic surgeons' examinations. After an average follow-up of 2 years, outcomes regarding vermilion border, philtrum symmetry, function of the orbicularis muscle, and lip volumetric symmetry were successful, and none of the patients experienced new notch formation, muscular functional loss, lip volume loss, or asymmetry. Owing to good muscular function preventing the stretching, the postoperative scars become more acceptable to the patients. The technique has proven to be safe and successful through the GAIS objective assessment, as also confirmed by the examinations of the three independent surgeons, while the majority of patients reported an exceptional improvement in the appearance alongside a more than 95% satisfaction rate with the operation. In conclusion, our findings revealed successful functional and aesthetic outcome of using J: -shaped scar tissue flaps in secondary repair of cleft lips. The technique was associated not only with the correction of significant secondary deformities yielding an improved and symmetrical lip volume, correction of vermilion notch, and prevention of notch re-formation but also with the restoration of orbicularis oris muscle function and thus integrity of the lip with minimal scarring.

Preoperative analysis of upper lip in patients with upper cleft lip/palate before lip repair

Background

The postoperative morphological appearances vary widely patients with unilateral cleft lip with or without cleft palate (UCL/P), whether it is complete or incomplete cleft. The main reason of bilateral lip asymmetry after cleft lip surgery lies in the lack of personalized measurement and design before surgery. In this study, we aim to individually investigate areas of the upper lip on cleft and non-cleft sides in patients with unilateral cleft lip with or without cleft palate (UCL/P).

Methods

Ninety-two patients with UCL/P (group 1: <1 year, group 2: 1–2 years) were included in the study. Group 1 included 37 patients with incomplete UCL/P and 29 with complete UCL/P; group 2 included 11 and 15 patients, respectively. The total area of the upper lip on the cleft side (Q8) was divided into Q3, Q4, and Q5 (further divided into a1 and a2), and the upper lip on the non-cleft side (Q7) was divided into Q2 and Q1 (further divided into A1 and A2). Area ratios between the cleft and the non-cleft sides were calculated, and certain parameters were tested for correlations with these ratios.

Results

Values of Q8/Q7 were partially overlapped between patients with complete and incomplete UCL/P. Significant correlations were noted between differences in height of the philtrum column (a–h) and the prolabial area ratio between the cleft and the non-cleft side (Q3/Q2) (P=0.032). Moreover, a significant correlation was noted between a1/A1 and the ratio of the lateral labial area between the cleft and the non-cleft side (Q5/Q1) (P=0.001).

Conclusions

The conventional classification of unilateral cleft lip as incomplete and complete does not completely and accurately reflect individual malformations. Therefore, it is necessary to analyze unilateral cleft lips individually to determine the repair technique and to predict postoperative outcomes.

Cleft lip repair: are outcomes between unilateral and bilateral clefts comparable?

This study sought to compare patient demographics, operative course, and peri-operative outcomes between unilateral and bilateral cleft patients. Primary cleft lip repairs were isolated from the National Surgical Quality Improvement Program Pediatric Database (NSQIP-P). Unilateral and bilateral cases of primary cleft lip were identified by ICD codes. Demographics, comorbidities, and post-operative outcomes were compared between cohorts. Patients were propensity matched to control for differences before repeating the analysis. About 4550 cleft lip repairs were evaluated over the 5-year period. Of the cases where the cleft type was identifiable, 75.5% were unilateral clefts and 24.5% were bilateral clefts. The bilateral cleft population had significantly more comorbidities including higher rates of ventilator dependence (1.0% versus 0.4%, p = 0.02), asthma (1.6% versus 0.7%, p = 0.011), tracheostomy (1.6% versus 0.5%, p < 0.001), gastrointestinal disease (16.9% versus 12.7%, p < 0.001), previous cardiac surgery (3.6% versus 2.2%, p = 0.015), developmental delay (9.9% versus 4.6%, p < 0.001), structural central nervous system abnormalities (5.0% versus 2.5%, p < 0.001), and nutritional support (8.0% versus 3.2%, p < 0.001). Following propensity matching, there were no significant differences in complications, readmissions, or reoperations between the cohorts. Patients with bilateral cleft lip have significantly more comorbidities than unilateral cleft lip patients. However, peri-operative outcomes are comparable between the groups.
