Comparing the treatment protocols for cleft lip and palate requires a study of facial growth and development. Serial orthodontic study models aid in delineating the effects of surgery on maxillary mandibular relationships. In 1978, a new protocol, POPLA (presurgical orthopedics followed by periosteoplasty and lip adhesion), was developed and put into practice. This article compares the results obtained using POPLA (group I) with those using the previous method (lip adhesion alone) (group II) for cases of unilateral and bilateral clefts. Complete orthodontic study models were available for 124 patients, 63 in group I and 61 in group II. Specific timing sequences and surgical details are discussed. Dental cast analyses evaluated alveolar gap, arch width, anteroposterior distance, incisor crossbite (single tooth and multiple tooth), and buccal crossbite (single and multiple tooth) at birth and at 3, 6, and 9 years of age. X-ray studies evaluated the bony bridge. Additional comments are made regarding the incidents and effects of pharyngeal flaps and bone grafts on maxillary-mandibular relationships. Results included less buccal crossbite in the POPLA group, with a wider transverse distance of the upper dental arch. There was a greater frequency of anterior crossbite in the POPLA group, and the anteroposterior distance was shorter at 6 years of age but less so by age 9. This may be because of the different orthodontic care received by the patients in the two groups. In conclusion, the POPLA approach achieves the main goal of moving the palate into a normal position and stabilizing the arch with a bony bridge that attracts teeth. It avoids the difficult anterior fistulae and presents a more symmetrical platform upon which the lip can be united and the nose can be corrected early.
Background. There have been few reported series of liposarcomas in patients younger than or equal to 22 years of age.
Methods. A retrospective analysis of all patients presenting with liposarcoma between 1949–1990 at Memorial Sloan‐Kettering Cancer Center with age at diagnosis younger than or equal to 22 years was performed. Variables evaluated for their predictive effect on survival included anatomic location of the primary, size, and completeness of surgical resection.
Results. Eighteen patients were identified. Only 1 patient (6%) presented with a high‐grade lesion, and in 13 patients (72%), the myxoid subtype was observed. All but one patient undergoing complete resection remain disease‐free 1.3–29.1 years after treatment, while all patients with gross residual tumor have died from disease. Two of three patients with microscopic residual at resection are disease‐free 2 and 11.8 years after diagnosis with the addition of external beam radiation therapy.
Conclusions. The authors conclude that complete surgical resection is crucial for survival in young patients with liposarcoma and that external beam radiation therapy may be effective against microscopic residual.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
