Dental-Facial Midline: An Esthetic Based Classification

Background: The facial midline and dental midline play an important role in facial esthetics, cosmetic dentistry, facial plastic surgery, and anthropologic studies. Objective: This study studied the dental-facial midline in Nepalese subjects and to classify the midline. Methods: The study was conducted in 150 Nepalese subjects, mostly consisting of University students (80 males and 70 females). After obtaining ethical approval, facial and dental midlines were analyzed using a scale. Results: It showed 26 (18%) study subjects showed the coincidence of the facial midline with the maxillary and mandibular dental midlines. It showed that only 44 (30%) subjects showed the coincidence of facial midline with only maxillary dental midline, and 26 (17%) subjects showed the facial midline coincidence with only mandibular dental midline. The dental midline discrepancy was more prevalent in the maxillary arch and more prevalent on the right side. Midline discrepancy is seen more in males compared to females. The majority of the deviation showed 1 mm, followed by 2 mm, and 3 mm. Conclusion: The coincidence of the facial midline with both the maxillary and mandibular dental midlines is uncommon. Midline discrepancy is seen more in males compared to females. The majority of the subjects show a mild discrepancy of 1 mm. The midline discrepancy was more seen on the right side and in the maxillary arch.

Margin Control

Background: Mohs micrographic surgery (MMS) is an important part of non-melanoma skin cancer (NMSC) management but may even be useful for tumors that cannot be cleared in an office setting. There are sparse reports of MMS for peripheral margin control in the dermatology literature but various techniques have been reported.Case 1: 58-year-old male with morpheaform basal cell carcinoma of the left midface treated with MMS peripheral margin control followed by facial plastic surgery central tumor extirpation and defect repair.Case 2: 56-year-old female with recurrent morpheaform BCC of the scalp treated with MMS peripheral margin control followed by facial plastic surgery central tumor extirpation and defect repair.Case 3: 73-year-old male with multiply recurrent SCC of the right lower extremity treated with MMS peripheral margin control followed by above the knee amputation.Conclusions: MMS peripheral margin control followed by central tumor extirpation and defect reconstruction at a later date in the operating room is an option for deeply invasive, large and aggressive NMSC. Benefits include decreased time under general anesthesia and superior rates of tumor clearance. In the interim, the peripheral defect between the central tumor and healthy outer tissue can be sutured closed to decrease patient morbidity.
