Understanding Scar Assessment in Cleft Lip Repair
Evaluating the quality of scars after cleft lip repair is essential for both surgical outcomes and patient satisfaction. Surgeons, researchers, and families all want to know whether a scar is healing well, how visible it is, and how it might change over time. To do this reliably, clinicians need scar assessment tools that are both simple and scientifically robust. One such tool is the Stony Brook Scar Evaluation Scale (SBSES), designed to provide a structured, reproducible way to rate scar appearance.
The SBSES focuses on clear, observable characteristics of a scar and turns them into a numeric score. This makes it easier to compare results between patients, between surgical techniques, and over long-term follow-up. When applied to cleft lip repair, it helps bridge the gap between subjective impressions and objective measurement.
What Is the Stony Brook Scar Evaluation Scale?
The Stony Brook Scar Evaluation Scale is a clinician-rated scoring system originally developed to assess surgical scars. It is particularly valued for its balance of simplicity and reliability. Instead of relying solely on broad impressions of whether a scar looks “good” or “bad,” it breaks scar quality down into specific visual features that can be observed consistently across different raters.
Each of these features, or parameters, is given a binary score, and the sum of those scores reflects the overall aesthetic quality of the scar. Because it uses easily recognizable criteria, the SBSES can be used in busy clinical settings without requiring complex instruments or extended training.
Key Parameters of the SBSES
The SBSES evaluates several core features of a scar. While specific implementations can vary slightly across studies, the scale typically includes the following parameters:
- Width – Whether the scar is narrow and well-approximated or widened and spread.
- Height – Whether the scar is flat relative to the surrounding skin or raised/depressed.
- Color – How well the scar color matches the adjacent skin, with more obvious discoloration lowering the score.
- Edge Contour – Whether the wound edges are well aligned and smooth or irregular and step-off in appearance.
- Overall Appearance – A global impression of the scar’s cosmetic quality, judged in the context of all other features.
Each favorable feature earns one point, and the points are added to produce a total score. Higher scores indicate better cosmetic outcomes, while lower scores suggest more conspicuous or unfavorable scarring.
Why Scar Evaluation Matters in Cleft Lip Repair
Cleft lip repair is not only about restoring function; it is also about achieving the best possible facial aesthetics. The lip is central to expression, speech, and social interaction, so even modest differences in scar quality can have significant psychosocial impacts. Objective scar evaluation tools, like the SBSES, make it possible to do more than rely on general impressions when judging the success of a repair.
In the context of cleft lip, scar assessment contributes to several important goals:
- Improving surgical techniques by comparing outcomes between different operative methods or refinements.
- Guiding postoperative care, including scar management, massage, and topical treatments.
- Supporting research into factors that influence scarring, such as age at repair or type of suture material used.
- Enhancing communication with families by providing a clear framework to discuss healing and long-term expectations.
Because cleft lip repair often occurs in infancy and is followed by many years of growth and change, a reliable, repeatable scoring system is extremely valuable for tracking progress.
Reliability and Validity of the SBSES
For a scar evaluation scale to be clinically useful, it must produce consistent results, not only when used by the same clinician over time, but also when used by different observers. Studies on the Stony Brook Scar Evaluation Scale have examined its reliability in these respects.
Interobserver reliability refers to how similarly different clinicians score the same scar. High interobserver reliability means the tool offers stable results across users, an essential feature for multi-center studies and for routine use by a team of providers.
Intraobserver reliability describes how consistent a single clinician is when scoring the same scar at different times. Strong intraobserver reliability indicates that the scoring method is clear and not overly sensitive to minor day-to-day variations in perception.
Within cleft lip research contexts, the SBSES has demonstrated solid reliability in both dimensions. This supports its use as a standardized measure in clinical trials and outcome studies, where consistency is crucial for meaningful comparisons.
Applying the SBSES to Cleft Lip Scars
When the SBSES is adapted for cleft lip evaluation, clinicians typically perform standardized photographic documentation or in-person examinations. The scar is viewed under consistent lighting, and the same angles are used each time to minimize variability in appearance.
Using the SBSES in this setting often follows a structured workflow:
- Image capture or clinical exam with an emphasis on clarity and reproducibility.
- Independent scoring by trained observers, ideally blinded to surgical technique or patient details when used in research.
- Data collection and comparison across time points, patients, or techniques to identify patterns.
- Integration with patient feedback, including satisfaction surveys and quality-of-life measures, to align objective scores with lived experience.
Through this process, surgeons and researchers can systematically identify which approaches produce the most favorable scars and adjust their protocols accordingly.
Clinical and Research Implications
The structured nature of the SBSES enhances both day-to-day clinical practice and long-term research. Clinically, it allows teams to track their own performance over time, highlighting areas where minor changes in technique may yield better cosmetic outcomes. It can also help in counseling families, illustrating how scars typically evolve as children grow and how scores may improve with maturation and targeted interventions.
In research, the SBSES supports evidence-based decision-making. It provides a common language and numerical endpoint for comparing variables such as incision design, closure method, or adjunctive therapies like steroid injections or silicone-based treatments. By understanding which factors most strongly affect scar quality, clinicians can refine their approaches and share best practices more effectively.
Limitations and Considerations
Like any clinical tool, the Stony Brook Scar Evaluation Scale has limitations that must be acknowledged. It focuses on visible features and may not fully capture functional aspects such as scar tightness or impact on lip mobility. It is also a clinician-based measure and does not directly incorporate the patient’s or family’s subjective perception of the scar, which can be influenced by cultural, psychological, and social factors.
Furthermore, while binary scoring promotes simplicity and consistency, it may overlook subtle gradations in scar quality. In complex cases, or in advanced research settings, the SBSES may be complemented by additional scales or instruments that evaluate texture, sensitivity, or three-dimensional contour in more detail.
Best Practices for Using the SBSES in Cleft Lip Care
To get the most value from the SBSES, teams benefit from adopting consistent protocols and training. Some practical recommendations include:
- Standardizing photography with fixed positions, lighting, and camera settings.
- Providing short, focused training for all observers, including examples of scars and benchmark scores.
- Using multiple raters in research contexts to strengthen the reliability of findings.
- Combining SBSES scores with patient-centered outcome measures when possible.
- Reviewing aggregate data periodically to identify trends and opportunities for improvement.
By embedding these practices into routine care, the SBSES can become more than a research instrument—it can serve as a continuous quality improvement tool within cleft lip programs.
Future Directions in Scar Evaluation
The growing emphasis on aesthetic outcomes and patient quality of life in cleft care is driving innovation in scar assessment. Future developments may include digital analysis of scar images, three-dimensional imaging, and integration of artificial intelligence to quantify color, texture, and contour. In this evolving landscape, the SBSES remains a valuable benchmark—simple enough for everyday use yet structured enough to underpin rigorous studies.
As research expands, combining objective scores like those from the SBSES with patient-reported outcomes and long-term follow-up will help create a more complete picture of success in cleft lip repair. Ultimately, this integrated approach aims to ensure that surgical excellence is matched by scars that are as inconspicuous and harmonious as possible with each patient’s unique facial features.
