Insights
This study analyzed rare craniofacial cleft (RCC) patient data, finding Tessier 7 clefts most common. Surgical repair using aesthetic units and Z-plasty improved facial balance and outcomes, objectively measured by the Versnel scoring system.
Area of Science:
- Plastic Surgery
- Craniofacial Surgery
- Pediatric Surgery
Background:
- Rare craniofacial clefts (RCC) present unique challenges in primary repair.
- Understanding clinical characteristics and associated abnormalities is crucial for effective treatment planning.
Purpose of the Study:
- To investigate clinical characteristics of rare craniofacial clefts based on Tessier classification.
- To evaluate surgical outcomes of primary repair for rare craniofacial clefts.
Main Methods:
- Retrospective study of 30 patients with rare craniofacial clefts.
- Analysis of clinical data including Tessier classification, gender, affected side, and associated abnormalities.
- Surgical correction using aesthetic units with multiple Z-plasty; outcomes assessed with the Versnel scoring system.
Main Results:
- Tessier 7 cleft (T7) was the most frequent type, followed by T0.
- Unilateral clefts were more common than bilateral clefts (76.5% vs. 23.5%).
- Specific cleft types showed predilection for certain facial structures (orbit, nose, mouth, ear).
- Surgical repair improved facial balance and restored key landmarks with acceptable scarring.
- The Versnel scoring system provided objective outcome measurement.
Conclusions:
- Rare craniofacial clefts exhibit diverse clinical presentations and can be associated with syndromes or other abnormalities.
- Primary repair of rare craniofacial clefts using aesthetic units and Z-plasty yields favorable aesthetic and functional results.
- The Versnel scoring system is a valuable tool for objectively evaluating surgical outcomes in rare craniofacial cleft repair and assessing growth influences.
Abstract:
This study aimed to investigate the clinical characteristics according to Tessier classification and evaluate the surgical outcomes in patients with rare craniofacial cleft (RCC) primary repair. A retrospective study on 30 patients with RCC was conducted at the Department of Craniofacial and Plastic Surgery of the Vietnam National Hospital of Pediatrics. Rare craniofacial cleft was recorded according to Tessier's classification and was analyzed for gender, affected side, clinical characteristics, and associated abnormalities. Primary surgical correction was based on the concept of aesthetic units with multiple Z-plasty. Preoperative deformities and postoperative outcomes were evaluated with anthropometric measurements using the Versnel scoring system. The most common type was Tessier 7 cleft (T7), followed by T0. There was no difference between the frequency of males and females. Patients with unilateral cleft accounted for a larger proportion than bilateral cleft (76.5% versus 23.5%; P = 0.029 <0.05). The median and paramedian cleft groups (T0, T1, T30) affected orbit 22.2%-nose 77.8%-mouth 44.4%. The oblique clefts (T3, T4, T5, T11) affected orbit 100%-nose 50%-mouth 50%. The transverse cleft group (T6, T7, T8) affected mouth 94.1%-ear 29.4%. Rare craniofacial cleft may present alone or in a syndrome (Treacher Collin, Goldenhar, Hemifacial atrophy), or in combination with other abnormalities. Repairing RCC with aesthetic units with multiple Z-plasty has improved facial balance and restored key landmarks with acceptable scar position. The Versnel scoring system can serve as an objective instrument to measure the surgical outcomes of RCC repair and can be used to evaluate the influence of growth.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
