Our method of performing an auricular composite graft for a skin defect of the philtrum dimple in a patient whose lip is not damaged and has retained its original softness and elasticity is presented. After resecting the lesion, an auricular composite graft is harvested from the conchal region. The size of the graft is almost the same as the size of the resected lesion, although the cartilage is harvested in an elliptical shape, and its size is approximately 60% in area of the overriding skin of the graft. The graft is harvested from the site, which has a similar curvature to the defect. The cartilage is sutured tightly to the graft bed at a minimum of four points with 6-0 absorbable suture. The transversal axis of the harvested cartilage is sutured as vertically as possible so as to fit the direction of the wrinkle line of the upper lip. The skin is sutured to the defect margin using 5-0 nylon suture. The graft donor site is closed primarily. This method has been used for the closure of six comparatively large skin defects after resecting a skin lesion (pigmented nevus in three cases and hypertrophic scar in three cases) in the philtrum dimple in six patients. In all cases, the upper lip was not damaged and retained its original softness and elasticity. The "take" of the graft was complete in all patients, and the donor site healed without any problem. In all cases, postoperative shrinkage of the graft was not significant during the follow-up period, and the graft had a smooth surface. In addition, no patients suffered from a feeling of discomfort in moving the mouth, and an acceptable shape of the philtrum dimple was achieved in all cases. There were no deformational changes in the graft donor site. In conclusion, our method is valid in the patient whose lip is not damaged and has retained its original softness and elasticity and in whom a full-thickness skin graft is selected as the covering method for a skin defect of the philtrum dimple.

Introduction: Recreating the philtral ridge and restoring orbicularis oris muscle continuity in cleft patients is a challenging task. Our muscle to sub-dermis technique introduces an effective method for achieving the desired philtral ridge reconstruction.
Method: From August 2015 to July 2023, a retrospective study was conducted with a follow-up period of at least 6 months.
Philtrum reconstruction in patients with unilateral cleft lip is a major concern in cheiloplasty. Moreover, a quantitative evaluation of the philtrum contour has not been possible. Advances in 3-dimensional (3D) imaging technology have enabled highly accurate assessments of facial surfaces.

Nablus mask-like facial syndrome (NMLFS) (OMIM: 608156) is an extremely rare genetic syndrome first reported by Ahmad Teebi in 2000. Although it is a rare condition, it is characterized by distinctive facial features such as, expressionless facial appearance, tight, glistening facial skin, low anterior hairline, sparse eyebrows, small palpebral fissures (blepharophimosis), hypertolerism, bulbous nose with prominent columella, abnormally short nose and flat nasal bridge, abnormal ear configuration, bilateral longitudinal cheek dimples, everted lower lip, long philtrum, and maxillary hypoplasia. In addition, a happy and friendly disposition is considered to be the common symptom of this syndrome.

Background: The orbicularis oris muscle is an important muscle for oral perception in mouth and swallowing rehabilitation. The muscle can be affected in patients with multiple sclerosis for many reasons. It is important to understand the quantitative changes in this muscle to determine the many problems associated with the cranio-facial region in multiple sclerosis.

Article Synopsis
- Patients with schizophrenia display reduced facial expression and impaired emotion recognition, which are linked to negative symptoms of the disorder.
- The study involved 135 patients and 134 healthy controls, measuring facial muscle activity in response to various emotional stimuli to assess the relationship with negative symptoms.
- Findings revealed that patients had significantly lower facial muscle activity in several areas compared to controls, with a positive correlation between specific muscle activities and the severity of negative symptoms.
