Lacrimal Gland Fixation with Postseptal Fat Transposition: A New Method For Asian Females
Lacrimal gland prolapse (LGP) is a condition that significantly affects the aesthetic appearance and functional aspects of the eyelid. LGP occurs when the lacrimal gland, responsible for tear production, descends from its normal position, often leading to bulging in the upper eyelid. This can result from aging, trauma, or congenital factors. This condition is particularly prominent in Asian females, and addressing it requires a nuanced understanding of ethnic anatomical differences and tailored surgical techniques. In this article, we will explore the anatomical differences in Asian female eyelids, detail traditional techniques for LGP and their limitations, and present an innovative modified technique that has shown promising results. This comprehensive guide aims to provide plastic surgeons with the necessary insights and skills to effectively treat LGP in Asian females.
Anatomical Differences in Asian Female Eyelids Affecting LGP
Asian female eyelids have unique anatomical characteristics that influence the presentation and treatment of LGP. Unlike their Caucasian counterparts, Asian females often exhibit low or absent lid creases and upper eyelid puffiness due to a prominent preaponeurotic fat pad, thicker skin, a more robust orbital septum, and differing fat distribution. Studies indicate that more than half of the Asian population has low or absent lid creases and upper eyelid puffiness, resulting in monolids. These features can obscure the lacrimal gland prolapse, making diagnosis and treatment more challenging. The goal of cosmetic blepharoplasty in these patients is not just rejuvenation but achieving a distinct eyelid crease and natural upper eyelid contour.
Why Lacrimal Gland Repositioning (LGR) is Needed
LGR is crucial for restoring the aesthetic balance of the eyelid and preventing chronic irritation and discomfort caused by the prolapsed gland. For Asian females, LGR can be particularly beneficial in achieving a harmonious and youthful appearance, complementing overall periorbital rejuvenation.
Traditional Techniques and Their Limitations
Traditionally, three methods have been used to treat LGP:
Light Cautery: This method involves using heat to cauterize and shrink the prolapsed gland. However, it may impair the ocular lubrication system, leading to dry eye symptoms.
Partial Excision: This involves the surgical removal of a portion of the prolapsed gland. Like light cautery, it can negatively affect tear production and ocular lubrication.
Suture Reposition: This method repositions the gland by suturing it to the periosteum of the lacrimal fossa, superotemporal orbital rim, or the orbital rim using drilled holes.
Light cautery and partial excision can impair the ocular lubrication system, leading to complications such as dry eye syndrome. Therefore, surgical refixation is widely adopted. There are two primary principles for surgical correction:
Repositioning the Prolapsed Gland:Â This involves suturing the gland to the periosteum of the lacrimal fossa or the superotemporal orbital rim.
Strengthening Supporting Structures: This involves suturing Whitnall’s ligament to the periosteum of the orbital rim.
These methods, however, often leave Asian females with unnatural and hollow upper eyelids. The prolapsed gland's repositioning alone does not address the excess preaponeurotic fat, which is a significant factor in these patients.
Limitations:
Inadequate Fixation: Traditional methods often fail to provide long-term stability, leading to a higher recurrence rate of up to 30% within two years post-surgery.
Visible Scarring: Standard incision techniques can result in more noticeable scars in Asian skin, where hypertrophic scarring and keloid formation are more common.
Incomplete Correction: Traditional methods may not adequately address associated issues such as ptosis or eyelid asymmetry, leaving unnatural and hollow upper eyelids, especially in young Asian females in their 20s.
Statistics on Traditional Techniques:
A study indicated that these traditional methods often result in less satisfactory outcomes for Asian females. Among the patients treated with conventional repositioning methods, a significant proportion experienced undesirable hollowing of the upper eyelids, leading to further corrective procedures. Recurrence rates for traditional techniques can be as high as 30% within two years post-surgery due to inadequate fixation and improper handling of the unique anatomical features.
Modified Technique and Its Advantages
Recognizing the limitations of traditional methods, a modified approach was developed: Lacrimal Gland Fixation combined with Postseptal Fat Transposition. This innovative technique integrates the fixation of the lacrimal gland with the transposition of preaponeurotic fat to provide both structural support and cosmetic enhancement. This approach is particularly advantageous for Asian females due to their unique anatomical features.
The New Method: Lacrimal Gland Fixation with Postseptal Fat Transposition
Enhanced Dissection and Exposure
Thicker Skin Consideration: Surgeons make deeper incisions and perform meticulous dissections to navigate the thicker skin and robust orbital septum, ensuring complete exposure and effective repositioning of the gland.
Precise Gland Repositioning: Using finer sutures and advanced fixation techniques, the gland is securely repositioned, minimizing the risk of recurrence.
Optimized Incision Planning
Minimizing Scarring: By placing incisions within natural creases and combining them with blepharoplasty incisions, surgeons reduce the risk of noticeable scarring.
Advanced Suture Techniques: Employing fine sutures and tension-free closure methods helps prevent hypertrophic scars and keloids.
Integrated Aesthetic Procedures:
Combining with Double Eyelid Surgery: Incorporating LGR with double-eyelid surgery or blepharoplasty ensures a seamless and harmonious enhancement of the eyelid, catering to the aesthetic preferences of Asian patients.
Fat Transposition: Utilizing fat transposition techniques to redistribute orbital fat not only supports the repositioned gland but also enhances the eyelid's contour and volume.
Surgical Procedure for LGR in Asian Females
A thorough assessment includes evaluating the degree of prolapse, the overall eyelid anatomy, and the patient's aesthetic goals, with special attention to skin thickness, the position of the orbital septum, and fat herniation.
The supine test is used to diagnose LGP accurately. This test involves the patient lying supine, which reveals the prolapsed gland if present.
Step 1: Incision and Exposure:
An incision is made through the upper eyelid crease, which is often combined with a blepharoplasty incision to minimize additional scarring. The incision should be planned meticulously to follow the natural contours of the eyelid, ensuring that post-surgical scars are as inconspicuous as possible.
Step 2: Dissection
Careful dissection is performed to expose the prolapsed lacrimal gland and the preaponeurotic fat pad. This step requires precise and delicate handling to navigate the thicker skin and robust orbital septum typical of Asian patients. The aim is to fully expose the gland while preserving the integrity of the surrounding tissues.
Step 3: Gland Fixation The prolapsed gland is gently repositioned to its anatomical location. This involves carefully lifting the gland and placing it back into the lacrimal fossa. Secure fixation is achieved using sutures, ensuring the gland remains in place without undue tension. The sutures should be fine and precisely placed to provide stability without causing additional trauma to the delicate tissues.
Step 4: Fat Transposition
Excess preaponeurotic fat is transposed to the site of the gland fixation to prevent hollowing and provide a smooth contour. This involves repositioning the prolapsed fat to areas where it can provide additional volume and support, enhancing the overall aesthetic outcome. The fat is carefully redistributed to smooth out any hollows or uneven areas, creating a more youthful and balanced appearance.
Step 5: Closure
The incision is closed with separate sutures to ensure proper healing and minimize scarring.
Why It Works:
Anatomical Compatibility:Â This technique takes into account the unique anatomical features of Asian eyelids, ensuring a more natural appearance. By understanding the specific needs and expectations of Asian patients, surgeons can create an eyelid shape and contour that is harmonious with their natural features.
