Objective To clarify the clinical features of the microform cleft lip and to establish the ultrastructural characteristics of the orbicularis muscle. Design Clinical observations of the characteristic deformities and associated anomalies were made. Muscle biopsies were harvested for histologic and ultrastructural analyses. Patients Seventy-one consecutive patients with microform cleft lip were included in the study. Muscle biopsies were investigated in 11 patients among them. Results Nasal…

"Three Subunit" Classification of Lesser-Form Cleft Lip and Muscle Analysis and Reconstruction of These Subunits Based on the Microanatomic Structures of Muscles in the Normal Upper Lip.

The microanatomic structure and the tension lines of the nasolabial muscles can provide new perspectives for better understanding and repairing the lesser-form cleft lip in subunits.

Dermis reconstruction and dermis fat grafting through an intraoral incision is effective in repairing a furrowed philtral column deformity in lesser-form cleft lip.


It is obvious from this study that all patients belongs to poor socio economics group, and all fathers were smokers, 3 patients born in parents who had cousin marriages and no history of mother’s exposure to radiation, drug abuse during gestational life.

A numerical classification system for cleft lip and palate in the dog.

This system is based on four topographic areas with a numerical representation of the severity of the cleft in each area and will reduce the need for experimental models of this condition.

Dental phenomics: advancing genotype to phenotype correlations in craniofacial research.

Improvements in two-dimensional and three-dimensional imaging and analytical techniques have allowed for accurate dental phenotyping, and efforts are ongoing to apply these in vitro techniques to the in vivo setting.

Microforma de fisura labial superior incompleta unilateral. Reporte de un caso

La microforma de fisura labial es una expresion de la fisura labial superior incompleta que se caracteriza por un surco o depresion cutaneomuscular a lo largo del margen del filtrum, asimetria o



Pathophysiology of cleft lip muscle.

It is hypothesized that some of the morphologic deformities associated with cleft lip may cause a failure of mesenchymal reinforcement of the facial processes at a critical time in development.

Histologic, Histochemical, and Ultrastructural Analysis of Soft Tissues from Cleft and Normal Lips

There is no evidence of deficient neural supply in the cleft lip, and there are characteristic myopathic changes, in concert with the observed interstitial fibrosis, which may have far‐reaching implications for growth and function.

Mitochondrial Activity of Orbicularis Oris Muscle in Unilateral Cleft Lip Patients

The findings evinced both an increased oxidative metabolism and a generic inflammatory condition of that muscle, the nature of which must still be defined, although excluding an inherent metabolic myopathy of orbicularis oris muscle in unilateral cleft lip patients.

Rethinking isolated cleft palate: Evidence of occult lip defects in a subset of cases

Upper lip ultrasounds of 33 CP cases were evaluated retrospectively for the presence of discontinuities within the orbicularis oris muscle (OOM), raising the possibility that some CP cases may be misclassified.

Orbicularis oris muscle defects as an expanded phenotypic feature in nonsyndromic cleft lip with or without cleft palate

Comparisons of the frequency of discontinuities in the OO muscle in 525 unaffected relatives of individuals with nonsyndromic cleft lip  ±  cleft palate versus 257 unaffected controls confirm the hypothesis that subepithelial OO Muscle defects are a mild manifestation of the cleftlip phenotype.

Subclinical features in non-syndromic cleft lip with or without cleft palate (CL/P): review of the evidence that subepithelial orbicularis oris muscle defects are part of an expanded phenotype for CL/P.

Evidence is presented that subepithelial OO muscle defects show great promise for providing more accurate recurrence risk estimates to relatives in cleft families and inclusion of OO defects in the CL/P phenotypic spectrum should improve the power of genetic studies.

Cleft Lip: Unilateral Primary Deformities

The history, classification, anatomy, and controversies in the surgical management of unilateral cleft lip deformities are examined, allowing surgeons to formulate a reasoned, longitudinal management plan for their patients on the basis of the available current data.

A rational basis is presented for the surgical management of minimal clefting in its varying manifestations using the model of embryonic fields in which midline structures develop with paired, fused A fields.

Nasal Deformity and Microform Cleft Lip in Parents of Patients with Cleft Lip

Although small in size, this study of three case histories identified nasal and lip deformities in the patients' parents and suggested genetic evaluations of children with complete and incomplete cleft lips might also include thorough evaluation of their parents.
