A Hairy Situation: Laser Hair Removal after Oral Reconstruction

Intraoral laser hair removal: A scoping review

PURPOSE

Intraoral hair growth is a debilitating side effect of flap or graft-based oropharyngeal reconstruction. There is no standardized treatment, but groups have successfully eradicated unwanted hair growth with intraoral laser hair removal. This scoping review assesses the utility of laser therapy in managing this condition.

METHODS

This scoping review followed PRISMA-ScR guidelines. Ovid Medline, Embase (Ovid) and Scopus were queried using index terms and keywords. Resulting articles were reviewed for inclusion by two independent reviewers against inclusion criteria and relevant data were extracted.

RESULTS

The literature search yielded 297 articles, 22 of which met inclusion criteria. In total, 77 patients were treated: 38 patients with an Alexandrite laser, 19 with an Nd:YAG laser, 18 with a diode laser, and two with a CO2 laser. Complete response defined as 80% or more reduction in hair count was achieved in 70 patients (90%) and six patients (8%) achieved a partial response (10%-79% reduction in hair count). One patient (1%) with gray hair saw less than a 10% reduction in hair count. On average, 3.84 treatment sessions were needed, spaced 5.4 weeks apart. Treatments were well tolerated without major side effects.

CONCLUSIONS

This is the first scoping review assessing the utility of intraoral laser hair therapy and suggests it may be a safe and effective treatment. However, surgeons should advise preoperative hair removal when clinically feasible to mitigate this side effect as much as possible.

Clinical Application of Long-Pulsed 800-Nm Diode Laser Depilation Technology on Microtia Reconstruction in 965 Patients

BACKGROUND

The issue of hair growth on reconstructed ears has been a matter of concern for both patients and surgeons, despite the notable progress made in microtia reconstruction technology in recent times.

OBJECTIVE

This study aims to present the practical implementation of long-pulsed 800-nm diode laser depilation technology in the field of auricular reconstruction. Furthermore, it seeks to establish a comprehensive and standardized protocol for utilizing lasers in the reconstruction of microtia ears.

METHODS

A total of 965 patients (comprising 1021 ears) diagnosed with congenital microtia underwent treatment using 800-nm long-pulsed diode laser depilation. The participants received 1-3 treatment sessions with intervals of 25-30 days. To assess the effectiveness of the treatment, two independent observers compared photographs and measured the reduction in terminal hair count before and after the final session. Clinical outcomes were evaluated using VAS questionnaires, and any adverse events were diligently recorded.

RESULTS

The findings indicated that the utilization of the long-pulsed 800-nm diode laser was both safe and efficient in achieving hair removal during microtia ear reconstruction. As additional sessions were conducted, pain scores demonstrated a decline, while adverse reactions remained minimal.

LIMITATIONS

This is a retrospective single-institution study.

CONCLUSION

The application of a long-pulsed 800-nm diode laser has been proved to be a safe and effective method for removing hair during the process of microtia ear reconstruction, involving the use of a tissue expander and autologous costal cartilage. To achieve satisfactory results in hair removal, it was found necessary to repeat the shots procedure two to three times.

Laser Hair Removal for Intraoral Flaps: A Review

Importance: Laser hair removal is a noninvasive technique that has been used for patients with oropharyngolaryngeal hair growth related to surgical flap reconstruction after head and neck cancer resection. The purpose of this work was to perform a rapid review of the literature to determine the therapeutic relevance of laser hair removal and identify laser parameters. Observations: A total of 10 publications addressing depilation of the head and neck sphere were selected and analyzed. Conclusions and Relevance: Laser therapy appears to be a promising treatment for hair removal from flaps with few side effects. However, there is no scientific basis for a standardized protocol or determination of the superiority of laser hair removal over another treatment.

Successful hair removal on intraoral grafts using the diode laser: Report of two cases

AIM

The aim of this study was to describe the successful epilation of intraoral grafts using the diode laser system.

METHODS AND RESULTS

Two male patients at a 12-month follow-up - who underwent radical resection of oral cancer located in the mouth floor and tongue followed by reconstruction with cutaneous flap - showed hypertrichosis in the graft region, leading to dysphagia and dysphonia. The diode (980 nm) laser was performed for both cases in order to remove the ectopic hair. Excellent aesthetic and functional outcomes with total hair removal and alteration of the tissue surface were achieved.

CONCLUSIONS

There is no currently standard protocol for the laser epilation use on hairy grafts because each graft required a different number of sessions for total epilation. The diode laser system appears to be a successful therapeutic option for patients suffering from hypertrichrosis in the oral cavity.

Modified submental platysmal adipomyofascial flap: is it a reliable alternate reconstructive option for small- to mid-sized defects especially in male patients with oral/oropharyngeal cancer?

Purpose

To introduce modified submental platysmal adipomyofascial flap as a new and viable hairless locoregional option for reconstruction of small- to mid-sized defects after ablative surgery in oral/oropharyngeal cancer patients keeping in mind the present pandemic situation.

Methods

An observational retrospective study was conducted using modified submental platysmal adipomyofascial flap as a locoregional reconstructive option for both intraoral and oropharyngeal defects in early-stage oral/oropharyngeal cancer patients, from Jan 2016 to May 2020 in a tertiary care hospital. All patients in this study were male and the overall flap outcome was evaluated with post-operative follow-up.

Results

Out of 18 patients, in 4 patients modified submental platysmal adipomyofascial flap was used as a combination of flaps for reconstruction. Six patients (33.33%) underwent adjuvant radiation therapy/radiation chemotherapy. The long-term functions (speech and swallowing) and cosmetic outcomes were good in the majority of the patients. One patient (5.55%) had pinhole oroantral fistula. No patient had any major flap failure.

Conclusion

Modified submental platysmal adipomyofascial flap can be considered as a good alternative in male patients for reconstruction of small- to mid-sized oral cavity/oropharyngeal defects post-resection, especially during the prevailing pandemic crisis. It is an oncologically safe procedure with the major advantage of providing a hairless flap for oral cavity, tonsillar and BOT resection defects with lesser donor site morbidity.

Laser therapy for hair removal on grafts and flaps

The diversity and utility of laser procedures have increased over the recent years and nowadays, applications for medical and cosmetic reasons have increased considerably. Problematic intraoral and cutaneous hirsutisms have been described as a consequence of complex reconstruction usually after oncology surgery. We present three patients in whom hair removal laser was performed on grafts and flaps in different compromised anatomical areas: oral cavity, penis, and auricular pavilion. All three patients were men; in two of them the hairy graft was a consequence after oncologic surgery reconstruction whereas the third patient presented hair in his auricular pavilion after cochlear implant due to a congenital ear malformation. In all the patients, neodymium:yttrium, aluminum, garnet laser (Nd:YAG) (1,064 nm) laser was performed with excellent aesthetic and functional outcomes with only three sessions. Hair removal laser is a well-accepted and effective method of achieving permanent decrease in hair density. Several lasers have been used successfully, including the long-pulse Alexandrite (755 nm), the long-pulse diode (810 nm), and the Nd:YAG laser (1,064 nm). There is currently no standard protocol for laser use on hairy grafts or flaps and there is limited published data regarding skin graft revision to enhance aesthetics and function.

Intraoral Cutaneous Hamartomas-Clinicopathologic and Immunohistochemical Characteristics of 3 Cases

Intraoral cutaneous hamartomas (ICHs) are uncommon mucosal lesions characterized microscopically by a combination of cutaneous structures, including various stages of follicular and sebaceous elements. Due to their rarity, the clinicopathologic and immunohistochemical attributes of ICHs have not been thoroughly delineated. Three cases of ICH were identified from our records, and formalin-fixed paraffin-embedded sections were immunohistochemically stained with antibodies against androgen receptor, estrogen receptor, and progesterone receptor, p63, factor XIIIα, and CD34. All 3 ICHs involved the buccal mucosa with an M:F ratio = 2:1 and mean age = 42.3 years (age range: 27-61 years). ICHs presented as thickened, painless, white and yellow plaques or nodules of long duration, measuring 0.6-1.5 cm. No history of skin graft in the area of the lesions was reported. Histopathologically, the lesions showed aggregates of rudimentary folliculosebaceous structures. Although well-defined piloerector muscles were present in all cases of ICH, bona fide hair follicles and isolated hair shafts were identified only in 1 case. The overlying oral epithelium exhibited epidermis-like morphological features, while inflammation was generally absent. Immunohistochemically, strong and diffuse nuclear staining for androgen receptor and factor XIIIα was observed in the sebaceous glands, and estrogen receptor and p63 reactivity were confined exclusively to the peripheral basal cells, while progesterone receptor staining was negative in ICHs. CD34 diffusely decorated the lesional stroma. In conclusion, ICH is a rare lesion composed of cutaneous elements in an abnormal location. A predilection for the buccal mucosa is reported in the current study.
