The main objective of oncologic dermatologic surgery is the complete excision of skin tumors. During reconstruction of the defect, we must attempt to preserve function and cosmetic appearance. At the labial commissure, fibers from the superior and inferior portions of the orbicularis oris muscle intersect and the vermillion inserts onto the modiolus, a complex, cone-shaped structure at the angle of the mouth. Surgical reconstruction of the labial commissure is challenging because of the need to preserve sphincter function and cosmetic symmetry. We present a number of cases of surgical defects at the labial commissure and describe the reconstruction techniques used. We also propose an algorithm to help determine the most suitable technique for different cases.

Dermatofibrosarcoma protuberans (DFSP) is a low-grade, malignant, spindle cell tumour with an infiltrative growth pattern and a high local recurrence rate. Cases of oral DFSP are rare. This report describes a case of DFSP occurring in the labial mucosa.

: Surgical treatment of extensive tumors of the lower lip generates important defects in its structure and functions. Over time, a multitude of reconstruction options for these defects have been imagined. Unfortunately, the majority involve the use of both local and regional flaps, which either lack labial structure or disorganize the oral commissures as nodal oral function points.

Lip ulcers associated with endotracheal tube fixation are a known complication in adults, but their prevalence in neonates and preterm infants remains unclear. We report a case of a right oral commissure ulcer that developed during endotracheal tube fixation at the right oral commissure and left lateral decubitus positioning in an extremely preterm infant with unilateral pulmonary interstitial emphysema (PIE). A male infant was born at 24 weeks and four days of gestation, weighing 696 gm.

Vascular malformations (VMs) are congenital abnormalities of blood or lymphatic vessels, present at birth and growing proportionally with the individual. They are classified into types such as capillary, venous, lymphatic, and arteriovenous malformation (AVMs). Symptoms include discoloration, swelling, pain, or functional impairment, depending on the type and location.

Objectives: Despite the versatility of flap designs for lower lip reconstruction, the notion of orbicularis oris (OO) ring integrity was barely stressed. Traditional flap transfer leads to fibrous orientation inconsistency with the remaining OO. Therefore, the aim of this study is to share the experience of combining local flaps with depressor anguli oris (DAO) transfer for lower lip reconstruction and OO sphincter function restoration.
