ABSTRACT
Objective@#This study is to investigate the effectiveness of philtrum repairment for-microform cleft lip, using muscle tension line group reconstruction.@*Methods@#This is a retrospective study of 19 consecutively primary microform cleft lip repairment patients, from January 2015 to December 2017. All the patients were provided muscle tension line reconstruction (group 1) or traditional muscle repairment by horizontal mattress sutures (group 2). The philtral ridge and dimple were evaluated by scores. The statistical analyses were performed using unpaired t-test by Prism 6.0 software.@*Results@#The philtral ridge score was higher in group 1 than group 2 (4.15±0.56 vs. 2.73±0.32, P<0.01). The philtral dimple score of group 1 increased either, when compared with group 2 (2.36±0.50 vs.1.45±0.28, P=0.0004).@*Conclusions@#Functional reconstruction of philtrum, using muscle tension line group repair, has satisfactory results in philtral ridge and philtral dimple.
ABSTRACT
Objective@#This study is to investigate the outcome of unilateral cleft lip repairment using trilobate flap and nasal-labial muscle tension system reconstruction.@*Methods@#From January 2015 to December 2017, 264 children with unilateral cleft lip were performed cheiloplasty. For all the patients, trilobate flap was adopted. The tension lines group among nasal-labial muscles were reconstructed following a three-dimensional pattern. Long-term results were evaluated using postoperative photos. Three measurements were collected, to compare the nasolabial contour on the cleft side and noncleft side.@*Results@#Six to 12 months follow-up was completed in 112 patients. Asymmetry percentage of lip height was (2.98±1.65)%, while nostril width ratio was 1.02±0.05, and nostril height ratio was 0.94±0.04. Aesthetic contour of vermillion and philtrum were satisfied.@*Conclusions@#Trilobate flap technique combined with the reconstruction of nasal-labial muscle tension system have reliable effect on unilateral cleft lip repair. With proper application, satisfactory and stable outcomes can be achieved.
ABSTRACT
Due to insufficient understanding of the mechanism of the lesser-form cleft lip in clinical practice, the " muscle anatomical reduction" method, which is the general treatment option for the typical cleft lip, is also preferred for the treatment of lesser-form cleft lip, and the repair effect is often far from the patient′s expectation. Based on the anatomical study and clinical observation of the lesser-form cleft lip in more than ten years, the author systematically describes the characteristics regarding the disarrangement of muscle and explains the confusing clinical features of the lesser-form cleft lip. In addition, the pathological mechanism of the lesser-form cleft lip is further classified, and the muscle biomechanical biomimetic repair technique of this defect-" Yin′s nasolabial muscle frame" is proposed to guide clinical operations. This article preliminarily summarizes the author′s new understanding of the lesser-form cleft lip in recent years. The nasolabial Muscle Tension Lines Group(MTLG) theory is applied to analyze and solve puzzles in the lesser-form cleft lip. This process itself also serves as a clinical practice test of the MTLG theory.
