Long-term results after 40 years experience with treatment of rare facial clefts: Part 1--Oblique and paramedian clefts.

BACKGROUND: Oblique and paramedian rare facial clefts impose a major reconstructive challenge and long-term assessments of the outcomes remain scarce. This study provides new details regarding surgical techniques and timing, influence of growth, and difficulties of this pathology on the long-term; a guideline for surgical treatment is given. METHODS: Twenty-nine adults with an oblique or paramedian facial cleft and surgically treated in the authors' unit between 1969 and 2009, were included. The long-term evaluation was based on series of photographs, 3D-CT's, X-rays, operation data, and was specified per facial area. RESULTS: The mean number of performed operations per patient was 10.6 (range: 1-26). Vertical dystopia is not caused by previous surgery, but by growth deficiencies of the maxilla. In all patients with vertical dystopia, its presence and severity were clear at the age of five, and it should ideally be treated shortly after that age. In mild cases grafting seems sufficient, but in more severe cases orbital translocation is necessary. Costochondral grafts showed the best long-term results in both orbital and nasal reconstructions. Major nose reconstruction is best delayed until adolescence. For an optimal final result in selected cases, correction of midface hypoplasia at adolescence is necessary. CONCLUSION: The three-dimensional underdevelopment of the midface region plays a central role in the deformities of most patients, but is complex and difficult to correct. The provided guideline should help to minimize the number of operations and ameliorate long-term results.

Long-term results after 40 years experience with treatment of rare facial clefts: Part 2--Symmetrical median clefts.

BACKGROUND: Median facial clefts are reconstructive challenges, requiring multiple operations throughout life. Long-term results are often still far from ideal and could be improved. Due to surgical intervention and diminished intrinsic growth potential, surgical results may change from initially good into a progressively disappointing outcome. If, however, the ideal timing and type of surgery are known, in combination with the intrinsic growth potential, the results can be ameliorated. A guideline for surgical treatment is given. METHODS: Twenty patients with a pure symmetrical median cleft were evaluated on intermediate and long-term surgical results. The final result was scored based on severity of the initial and the remaining facial deformities, and the need for revisional surgery. RESULTS: The long-term surgical outcome was initially good for each of the affected facial parts and the face in general, but worsened over time, especially in the zone of the nose. An adequate and stable result of hypertelorism correction was observed for both the orbital box osteotomy and medial faciotomy, even when performed at a young age. CONCLUSIONS: The intrinsic growth restriction is mainly localised in the central midface. This leads to a complex and often unpredictable growth of the maturing face. It makes it difficult to achieve perfect reconstructions. Caution with surgical interventions of the nose at a young age is required. Once the face has matured, a midface advancement and secondary nose correction should be considered for satisfactory projection. Early referral to a specialised centre is essential.

Guidelines for reconstruction of the eyelids and canthal regions.

A large number of reports are available on the options for reconstructing specific defects of the eyelids or (peri) orbital area, which may complicate decision making in choosing the most optimal technique for a particular defect. Based on more than 40 years' experience in reconstruction of eyelids and periorbital defects, combined with an extensive literature review, general principles on reconstruction are presented and illustrated. Surgical techniques are outlined with respect to anatomical layer, depth, size and location of the defect. Adherence to specific principles for eyelid and canthal reconstruction will lead to predictable, stable and functionally good results.
