Rhinoplasty. Rhinoplasty is the most commonly performed surgical procedure according to the American Society of Plastic Surgeons database. In contrast to adults, there are several important factors to take into consideration. The first is the age of the patient. Typically, the nose grows rapidly during the first 2 years of life and puberty. It is estimated that nasal growth ends at age 15 to 18 years for boys and age 12 to 16 years for girls.[17–19] Therefore, performing rhinoplasty in young patients involves the risk of inhibiting the growth of nose and midface secondary to scarring. Many surgeons defer performing rhinoplasty until 16 to 18 years of age for boys and 15 to 16 years of age for girls.[19,20]
Although plastic surgeons must carefully consider the age of the patient when considering cosmetic rhinoplasty, there are a few exceptions to this rule. Currently, there are several absolute indications for septoplasty: septal hematoma, septal abscess, severe deformity secondary to cleft lip, nasal fracture, acute nasal fracture, and subsequent traumatic nasal deformity and nasal dermoid cysts. Of these, the most relevant indication for plastic surgeons is rhinoplasty for cleft lip patients. It is commonplace to perform primary rhinoplasty in these patients at the time of cleft lip repair to prevent further asymmetry secondary to growth. This practice has provided improved symmetry and decreased revision surgery in this population.[21,22] There is a growing body of knowledge that teenagers with significant cosmetic nasal deformities undergo a lot of psychological trauma and bullying.
Otoplasty. Otoplasty is also a commonly performed procedure in patients younger than 18 years. It is estimated that the ears reach 90 percent of adult size by the age of 3, and otoplasty is typically performed in patients older than 5 years in the United States and the United Kingdom.[23–25] According to Gosain et al., American plastic surgeons decide on the age limit based on multiple factors: preventing the child from getting teased before the start of schooling, traditional teaching of performing otoplasty at the age of 5, anesthetic risks, and possible impairment of ear growth.
Currently, there are two schools of thought regarding the age limit. Some believe that teasing can start as early as preschool, and early surgery has benefits of more malleable cartilage without resurgence of ear cartilage growth.[23,26,27] Others believe that the surgery should be deferred until the child can become aware of the appearance of the ears, and participate in the decision-making. The senior author (R.J.R.) strongly feels that early otoplasty intervention is much more appealing and beneficial to this age group because of online and peer bullying at school and other peer events.
Despite the controversy, it is well studied that this patient population benefits from surgery. Children with prominent ears or ear deformities have lower self-confidence and are dissatisfied with their appearance, and they experience an improvement in self-esteem, happiness, and social experiences after surgery.[29,30] The decision to operate in this population is dictated mostly by the parents' anticipation of future psychosocial impact and possible bullying. Hong et al. found that these parents can experience significant decisional conflict preoperatively and few regrets after the procedure. Therefore, plastic surgeons must carefully consider the outcome before performing otoplasty in the pediatric population.
Reduction Mammaplasty. Reduction mammaplasty is another commonly performed procedure in adolescents. The indication for surgery is similar to that for adult breast reduction: back pain, neck pain, shoulder groove, and dermatitis. However, the impact of surgery on young breasts is completely different given that the patients complete their breast development at different ages (mean, 15 years; range, 11.8 to 18.9 years).
Adolescent patients can experience regrowth of breast tissue even after the procedure, leading to symptom recurrence. In the study by McMahan et al., 72 percent of patients reported regrowth of breast tissue postoperatively, and some patients experienced recurrent symptoms during their pregnancy, leading to repeated reduction. In addition to the recurrence of symptoms, the effect of surgery on postoperative lactation needs to be discussed with the patient. Many studies have been performed on this subject. It is estimated that 91 percent of patients can lactate and 65 to 69 percent of patients have successfully breastfed.[33–35]
Breast Augmentation and Liposuction. In contrast to the procedures discussed earlier, breast augmentation and liposuction in teenagers are controversial. Currently, the U.S. Food and Drug Administration has approved saline implants for women aged 18 years and older and silicone implants for women aged 22 years and older. In addition, the American Society of Plastic Surgeons recommends that cosmetic breast augmentation should be performed in patients who are at least 18 years old.
Teenage breast augmentation has been performed in patients who have suffered congenital or acquired breast asymmetry secondary to Poland syndrome, thoracic hypoplasia, or burn.[39,40] These patients typically undergo tissue expansion of the affected breast with or without latissimus dorsi flap for soft-tissue coverage.[39,40] In the second stage, an implant is placed to achieve unilateral breast reconstruction for symmetry. Although this is a widely accepted indication for teenage breast augmentation, cosmetic breast augmentation in this age group is not recommended because of psychological and emotional immaturity.
Similar to breast augmentation, teenage liposuction receives similar criticisms of performing cosmetic surgery in adolescents. Liposuction is rarely indicated in adolescents except in gynecomastia. Approximately 65 percent of adolescent boys experience gynecomastia during puberty because of a relative excess of estradiol compared with testosterone.[41–43] Similar to girls, adolescent male patients complete their puberty at different ages (range, 13 to 17 years). The majority of pubertal gynecomastia is a self-limited condition unless its duration is greater than 12 months. In these patients, liposuction with or without excision of tissue can be performed.
Nonsurgical Procedures. According to American Society of Plastic Surgeons 2016 database, teenage nonsurgical procedures accounted for 1 percent of the total nonsurgical population. Of these procedures, laser hair removal was the most commonly performed procedure (70,763), followed by laser skin resurfacing (28,799), and botulinum toxin type A injection (20,676). The popularity of these procedures has been steadily increasing given the accessibility and demand for a "quick fix" for "female mustache," "hairy back," and acne scarring. Although these procedures are frequently performed in adults with minimal side effects, performing them in adolescents should be approached with caution.
Currently, there is no established guideline on the suitable patient age for these procedures. Hair grows rapidly during puberty because of hormone changes, and it is generally recommended to defer the treatment until hormones stabilize. For the acne treatment, topical retinoids are routinely used.[47,48] The safety of this drug is well documented, and the U.S. Food and Drug Administration–approved age is 12 years. Given that acne can occur earlier than age 12, the majority of the drugs are given to children younger than 12 years as an off-label use unless tretinoin gel 0.05% (Atralin; Valeant Pharmaceuticals, Bridgewater Township, N.J.) is used (approved for 10 years old). In addition to early acne treatment, acne scarring treatment using microdermabrasion and erbium:yttrium-aluminum-garnet laser has become popular as well, because of short postprocedure downtime and improved skin appearance. Erbium:yttrium-aluminum-garnet resurfacing has been shown to achieve good results for ice-pick and shallow boxcar scars, and these procedures are being sought.
Injectables and Skin Care Products. In comparison to the 2015 American Society of Plastic Surgeons database, the number of injectables has increased by 5 percent in 2016. Of these, the use of hyaluronic acid has increased by 4 percent. This phenomenon is most likely secondary to a surge in "prerejuvenation" and celebrity worship in teenagers. Teenagers now believe that botulinum toxin type A can prevent wrinkles, and would like to "prevent aging" despite a lack of dynamic and static rhytides. This belief is widely propagated among adolescents without any scientific validation. Current U.S. Food and Drug Administration approval for botulinum toxin type A in teenagers includes treatment for blepharospasm/strabismus in patients older than 12 years. However, the majority of botulinum toxin type A is used off-label, and approximately 20,676 botulinum toxin type A injections were performed in 2016.
In addition to botulinum toxin type A, adolescents are receiving hyaluronic acids to the cheek and lips. This number has increased dramatically in the past year, which can be secondary to celebrity worship.[1,50] There is an increased number of photographs of celebrities with augmented cheeks and lips shown on television, social media, and magazines, and this phenomenon could have led to increased celebrity worship.
For skin care products, there is no consensus for at what age adolescents should start wearing them, and there is a lack of literature on this topic. However, the majority of public health recommendations support early sunscreen use with a sun protection factor of 15 or higher to minimize sunburns.[56,57] Currently, approximately 14 percent of boys and 20 percent of teenage girls routinely use sunscreen.
Safety of Teenage Plastic Surgery
Despite the increased popularity, there is a paucity of literature on the safety of teenage plastic surgery. Therefore, we have performed a computerized search of the MEDLINE database by means of OVID using the following search terms:
Reduction mammaplasty: reduction mammaplasty, breast reduction
Noninvasive procedures: laser, chemical peel, microdermabrasion, botulinum toxin type A, hyaluronic acid
The following limits were applied for each search term:
Age groups: all children (0 to 18 years)
The computerized search was performed in May of 2017. A total of 1195 articles were identified from the initial search: rhinoplasty, n = 54; reduction mammaplasty, n = 219; otoplasty, n = 191; breast augmentation, n = 150; liposuction, n = 206; laser, n = 323; chemical peel, n = 9; microdermabrasion, n = 12; botulinum toxin type A, n = 11; and hyaluronic acid, n =20. The abstracts of each article were reviewed and 107 studies of potential relevance remained: rhinoplasty, n = 14; reduction mammaplasty, n = 21; otoplasty, n = 62; breast augmentation, n = 0; liposuction, n = 2; laser, n = 4; chemical peel, n = 2; microdermabrasion, n = 2; botulinum toxin type A, n = 0; and hyaluronic acid, n = 0. Then, each article was reviewed, and the final 40 studies were selected: rhinoplasty, n = 5; reduction mammaplasty, n = 5; otoplasty, n = 20; breast augmentation, n = 0; liposuction, n = 2; laser, n = 4; chemical peel, n = 2; microdermabrasion, n = 2; botulinum toxin type A, n = 0; and hyaluronic acid, n = 0 (Figure 3). All studies were reviewed by one of the authors (M.J.C.).
Rhinoplasty. Of the 14 studies, only five discussed the complications and risks associated with teenagers. A total of 168 patients were studied in these five studies, and they experienced poor aesthetic results (9.5 percent), bleeding (0.6 percent), recurrence (3.6 percent), pain (1.2 percent), nasal obstruction (4.8 percent), deviation (3.6 percent), and no complications (26.2 percent). Interestingly, the most common complication was poor aesthetic results, which included wide dorsum, tip depression, short nose, hanging columella, nostril asymmetry, and pincushioning (Table 1).
Otoplasty. The otoplasty category had the most studies reviewing their postoperative outcomes (Table 1). Of the 20 studies, the most common complication was pain (7.8 percent), followed by suture-related problems (7.2 percent), recurrence (2.5 percent), asymmetry (2.5 percent), wound complications (2.3 percent), sensory problems (2.2 percent), poor aesthetic results (1.6 percent), infection (1.2 percent), revision (0.6 percent), scarring (0.5 percent), and other complications (0.4 percent).
Reduction Mammaplasty. Of the 21 studies selected for detailed review, five studies (2064 patients, age 12 to <20 years old) discussed their complications (Table 1). The most common complication was scarring (2 percent), followed by poor aesthetic result (0.8 percent), sensory loss (0.8 percent), bleeding (0.7 percent), infection (0.2 percent), seroma (0.2 percent), cardiorespiratory (0.2 percent), pain (0.1 percent), inability to breastfeed (0.1 percent), and nipple loss (0.1 percent).
Breast Augmentation and Liposuction. Of the 150 studies regarding breast augmentation, there were no retrospective or prospective studies on breast augmentation in adolescents. Of the 206 studies regarding liposuction, there were two studies regarding its use in gynecomastia and lipodystrophy secondary to congenital deformity (Table 1). The most common complication was revision (14.9 percent), followed by recurrence (6 percent), nipple retraction (3 percent), residual lipodystrophy (3 percent), hypertrophic scar (1.5 percent), and asymmetry (1.5 percent).
Noninvasive Procedures. The literature review of common noninvasive procedures revealed four studies regarding laser, two studies regarding chemical peel, and two studies regarding microdermabrasion (Table 2). For laser use, three studies used the laser for a burn scar contracture, and one study used it for hair removal. The majority of studies reported a no-complication rate of 33 percent, followed by erythema (26.4 percent), discoloration (5.7 percent), overgrowth (6 percent), and sensitization (2 percent).
For the chemical peel use, two studies evaluated its role in congenital melanocytic nevi. There were no reported complications except no response to the treatment (2.7 percent). There were two studies evaluating microdermabrasion in adolescents for vitiligo and acne scarring. The studies revealed that the majority of patients did not experience any complications, and the most common complication was burning sensation (21.4 percent).
Injectables. The search of the OVID database for botulinum toxin type A and hyaluronic acid in adolescents showed that there are no retrospective or prospective studies on their use. There was a case report on using botulinum toxin type A for blepharospasm in Schwartz-Jampel syndrome without complication data.
