Introduction

Ablepharon-Macrostomia Syndrome (AMS) is a rare genetic disorder characterised by distinctive physical anomalies primarily affecting the face, skin, and other body parts. Studies from the 1970s describe that AMS occurs due to a mutation in the TWIST2 gene, which is inherited in an autosomal dominant manner (Price et al., 1991). AMS’s hallmark features include ablepharon (absence of eyelids), macrostomia (abnormally large mouth), ear anomalies, and skin abnormalities (De Maria et al., 2017). AMS presents significant challenges not only in terms of physical appearance but also in the function and quality of life of affected individuals. In order to combat these physical anomalies, surgical intervention plays a vital role in managing the condition (Alexopoulos & Matchinski, 2021).

These interventions are essential for improving the aesthetic appearance and correcting functional impairments that can significantly improve quality of life. From protecting ocular health through eyelid reconstruction to enhancing speech and feeding capabilities by correcting macrostomia, surgical procedures offer hope for better outcomes in AMS patients (Feinstein et al., 2015).

Within this article, we will explore the various surgical interventions employed in the management of AMS, discussing the techniques, challenges, and outcomes associated with each. By examining these approaches, we aim to highlight the importance of a multidisciplinary surgical strategy in providing comprehensive care for individuals affected by this rare but impactful syndrome.

Correction of Macrostomia

Functional and aesthetic implications

Macrostomia is characterised by an abnormally wide mouth, posing significant challenges to AMS patients. Functionally, macrostomia impairs speech, feeding, and oral competence, leading to difficulties in daily activities and social interactions. Aesthetically, macrostomia contributes to the distinctive facial appearance associated with AMS, which can affect self-esteem and social integration (Bissonnette et al., 2019).

Surgical approaches

Surgical correction of macrostomia involves procedures such as commissuroplasty, which narrows the mouth to a more typical size while preserving or improving oral function. The technique often involves precise tissue rearrangement and suturing to ensure symmetrical and functional results, with careful consideration of the patient’s growth and development (Papagrigorakis et al., 2012).

Considerations for speech and feeding

Addressing macrostomia surgically requires careful planning to avoid negatively impacting speech and feeding abilities. Surgeons must consider the alignment of muscles involved in these functions, and postoperative therapy may be necessary to optimise outcomes (Yoshitatsu & Shiraishi, 2021).

Ear reconstruction and hearing improvement

Types of ear anomalies in AMS

Patients with AMS often present with ear anomalies, including microtia (underdeveloped ears) or anotia (absence of ears), which can lead to hearing loss and aesthetic concerns (Vegas et al., 2022).

Surgical options for ear reconstruction

Reconstructive surgery for ear anomalies may involve the use of rib cartilage grafts or synthetic implants to create a natural-looking ear. These procedures are typically staged and require meticulous planning to achieve symmetry and functionality (Li et al., 2023).

Addressing hearing impairment

Hearing loss in AMS patients may be due to structural abnormalities of the outer or middle ear. Surgical interventions, such as ossicular chain reconstruction or the placement of bone-anchored hearing aids (BAHA), can significantly improve auditory function (Feinstein et al., 2015).

Management of skin abnormalities

Common skin issues in AMS

AMS is associated with various skin abnormalities, including thin, dry, or wrinkled skin, which can lead to discomfort and an increased risk of infections (Bissonnette et al., 2019).

Surgical and non-surgical interventions

Management of skin issues may involve surgical excision of excess skin or corrective procedures for more severe abnormalities. Non-surgical approaches, including moisturising treatments and protective measures, are crucial in daily care (Feinstein et al., 2015).

Long-term care and management

Ongoing dermatological care is essential to manage chronic skin conditions in AMS patients. Regular follow-ups ensure that interventions remain effective and that new issues are promptly addressed (Alexopoulos & Matchinski, 2021).

Other surgical interventions

Genital anomalies

Genital anomalies, such as ambiguous genitalia, often require surgical correction to improve function and appearance. These procedures may also have implications for reproductive health (Bissonnette et al., 2019).

Musculoskeletal issues

AMS may involve musculoskeletal abnormalities, including limb deformities, which can be addressed through orthopaedic surgeries to improve mobility and function (De Maria et al., 2017).

Dental and orthodontic considerations

Dental anomalies, such as malocclusion, require coordinated care involving orthodontic treatment and possibly corrective jaw surgery to improve oral health and function (Papagrigorakis et al., 2012).

Multidisciplinary approach and timing of interventions

Importance of coordinated care

A multidisciplinary approach, involving plastic surgeons, dermatologists, orthodontists, and other specialists, is critical in managing the complex needs of AMS patients (Alexopoulos & Matchinski, 2021).

Factors influencing surgical timing

The timing of surgical interventions is influenced by factors such as the patient’s age, growth, and the severity of the abnormalities. Early intervention may be necessary for certain conditions, while others may be delayed to allow for optimal outcomes (Feinstein et al., 2015).

Long-term follow-up and additional procedures

Long-term follow-up is essential to monitor the success of surgical interventions and to plan for additional procedures as the patient grows and develops (Bissonnette et al., 2019).

Conclusion

Surgical management plays a vital role in improving the functional and aesthetic outcomes for patients with AMS. Each intervention requires careful planning and a multidisciplinary approach to ensure the best results (Alexopoulos & Matchinski, 2021).

Advancements in surgical techniques and genetic research hold promise for improving outcomes in AMS patients. Ongoing research and the development of new treatments are essential (Li et al., 2023).

Importance of ongoing research and support for patients

Continued support and research are crucial to enhancing the quality of life for AMS patients, offering hope for better management of this complex syndrome in the future (De Maria et al., 2017).
