Moustache Reconstruction in Patients With Cleft Lip

Maxillofacial Surgery and Hair Transplantation: Ethics with Expertise

Background

The hair transplantation has become widely popular aesthetic procedure. Hair transplantation being a relatively new field in maxillofacial surgery, several aspects raise issues and controversies. Follicular unit transplantation (FUT) and follicular unit extraction (FUE) are two commonly used and accepted techniques. Further, hair transplantation has been successfully used in correction of alopecia, cleft lip scars, post-burn or surgical scars, vitiligo and as an adjuvant to other maxillofacial procedures. Several maxillofacial surgeons have incorporated hair transplantation procedure into their aesthetic practice successfully. Sound knowledge of surgical technique, armamentarium and proper surgical planning are important for good results. A lot of debate has been there on minimum qualification for performing hair transplantation.

Purpose

The aim of this review is to highlight that an oral and maxillofacial surgeon can perform hair transplant surgery with perfection and can manage all associated complications with expertise.

Embryological approach to philtral hair sparsity in bilateral cleft lip deformities

OBJECTIVE

In bilateral cleft lip cases, surgeons have long known that the medial nasal prominence or prolabium is devoid of muscle. Despite cheiloplasty restoring orbicular muscle continuity, moustache hair growth is less developed on the philtral skin. We sought to understand this hair disparity.

BASIC PROCEDURES

The authors conducted a comprehensive literature search using reference materials on the physiological and pathological development of the face in utero and the PubMed database using the keywords 'embryology', 'bilateral cleft lip' and 'hair'.

MAIN RESULTS

In bilateral cleft lip, the normal fusion between the maxillary and intermaxillary process does not occur, and the migration of cranial neural crest cells (CNCC) is disturbed. CNCCs from different locations and with different myoblastic differentiation potential are arrested on each side of the cleft. Therefore, a reduced concentration of myoblasts and myocytes as well as hormone receptors in the medial process could hinders the normal physiological development of the different layers of the philtral skin and especially the skin appendages.

CONCLUSION

Philtral hair sparsity in patients with bilateral cleft lip can be explain by a defect in the migration of CNCCs to the prolabium, whose cells are not able to develop hair follicles, due to a disruption of the exchange of Wnt/β-catenin, EDA, and or Noggin signals and due to the absence of androgen receptor.

Facial Hair Transplantation for Transgender Patients: A Literature Review and Guidelines for Practice

BACKGROUND

Facial hair transplantation has become an increasingly popular modality to create a more masculine appearance for transmasculine patients.

OBJECTIVES

This aim of this study was to review the current literature regarding facial hair transplantation and provide recommendations and best practices for transgender patients.

METHODS

A comprehensive literature search of the PubMed, MEDLINE, and Embase databases was conducted for studies published through April 2020 for publications discussing facial hair transplant in transmasculine patients, in addition to the nontransgender population. Data extracted include patient demographics, techniques, outcomes, complications, and patient satisfaction.

RESULTS

We identified 2 articles discussing facial hair transplantation in transmasculine patients. Due to the paucity of publications describing facial hair transplantation in transmasculine patients, data regarding facial hair transplant from the cisgender population were utilized to augment our review and recommendations.

CONCLUSIONS

Facial hair transplant is a safe and effective means of promoting a masculine appearance for transgender patients. Nevertheless, facial hair transplantation should be deferred until at least 1 year after the initiation of testosterone therapy to allow surgeons to more accurately identify regions that would benefit the most from transplantation. Additionally, providers should engage patients in discussions about any plans to undergo facial masculinization surgery because this can alter the position of transplanted hairs. Currently, follicular unit extraction from the occipital scalp is the preferred technique, with use of the temporal scalp if additional grafts are needed. Patients should be advised that a secondary grafting procedure may be needed a year after initial transplant to achieve desired density.

[Secondary cheiloplasty in the treatment of cleft lip and palates]

In the course of treatment of cleft lip and palates, the quality of primary cheilo-rhinoplasty is essential to limit aesthetic and functional complications. This is why these primary reconstructions come under the domain of specialised centres with multidisciplinary teams. Unfortunately, residual imperfections often remain, especially in bilateral clefts, and secondary cheiloplasties represent for us a complex challenge. They aim at functional and aesthetic correction, and the choice of time is very random and depends largely on the psychological repercussions of the deformation in the child. It often occurs at the age of school entry and is combined with alveoloplasty. We then speak of alveolar transplantation with vestibulo and labio-plastie, the GPVP. Then we propose to combine all the resources of cosmetic surgery to improve the aesthetic and functional result of these children.

Follicular Unit Extraction (FUE) Hair Transplant: Curves Ahead

The hair transplant has become widely popular aesthetic procedure. Follicular unit transplantation (FUT) and follicular unit extraction (FUE) are two commonly used and accepted techniques. FUT requires excision of strip of tissue from occipital donor area leading to linear scar. To overcome scarring and other complications of FUT, FUE technique has been attempted which involves harvesting of small individual follicular units. Hair transplantation has been successfully used in correction of alopecia, cleft lip scars, post-burn or surgical scars, vitiligo and as an adjuvant to other maxillofacial procedures. FUE demands greater skills and orientation but can yield excellent results in experienced hands. Several maxillofacial surgeons have incorporated hair transplantation procedure in their aesthetic practice successfully. Sound knowledge of surgical technique, armamentarium and proper surgical planning are essential for desired results. The aim of this article is to explain FUE technique, risk and complications, holding solutions and other associated factors in detail. A simple protocol has been put forth for reference and for better understanding of the technique.
