Recurrence of Lower Eyelid Fat Pads (Herniated Fat) after Blepharoplasty: An Analysis of Different Operative Techniques ()
1. Introduction
Lower lid bulge is known as a part of the aging process. Lower lid bulge can be produced by one of 2 major mechanisms or a combination of them: herniated excessive intraorbital fat and/or weakening of supporting components of the lower eyelid, including skin, orbicularis oculi muscle, orbital septum, capsulopalpebral fascia, Lockwood ligament, and lateral canthus [2] [3] [4] [5]. Lee et al. [6] reported that total orbital fat (OF) volume and fat volume of anterior to the inferior orbital rim (IORF) increased significantly after 40 s in both male and female groups compared with that of the 20 s. The ratio of IORF to OF showed significant differences after 60 s compared with that of 20 s.
Therefore treating these anatomic changes and avoiding their recurrence is an important part of periorbital rejuvenation surgery.
Many techniques have been described to treat this fat compartment bulging, with different results and different recurrence average was reported in medical records.
We used 3 different techniques here concentrating on recurrences after fat pads removal.
2. Materials and Methods
110 patients are undergoing aesthetic upper and lower blepharoplasty in our Plastic and Reconstructive division in Almowasat Hospital in Damascus from 2018 to 2021.
46 patients who were well followed up were retrospectively reviewed and categorized into three groups according to the surgical techniques employed.
All patients have undergone upper and lower blepharoplasty surgery, without any other associated procedures like face lifting, brow lifting, midface lift, or fat injection in face.
All patients with previous periocular surgery were excluded from the study, also we did exclude patients with periocular diseases (such as blepharoptosis, dry eye syndrome, …)
It happened to be that all patients were females in the study but that was no inclusion chriteria.
2.1. Group 1 (15 Patients)
Upper and lower blepharoplasty with dissection of central and lateral part of lower eyelid orbicularis oculi muscle as flap (2 cm length, 0.5 cm width) from lower eyelid skin flap and suspension it on lateral orbital margin periosteum 2 mm above the level of the medial canthus via passing this muscle flap through a tunnel that was dissected beneath the skin flap lateral the lateral canthus and between the upper and lower blepharoplasty incisions (Figure 1).
This fixation of muscle flap was performed using 5/0 Nylon suture one mattress stitch (n = 15).
2.2. Group 2 (15 Patients)
Upper and lower blepharoplasty were done with lateral lower eyelid tarsal plate suspension on lateral orbital margin periosteum 2 mm above medial canthus level without creating previous lateral tunnel (Figure 2).
This fixation of lateral lower eyelid tarsal plate was also performed with 5/0 Nylon suture one mattress stitch (n = 15).

2.3. Group 3 (16 Patients)
Upper and lower blepharoplasty with suspension of both lower eyelid orbicularis oculi muscle dissected flap and lateral lower eyelid tarsal plate on the lateral orbital margin periosteum 2 mm above medial canthus level via passing these structures through the tunnel that was dissected beneath the skin flap lateral the lateral canthus and between the upper and lower blepharoplasty incisions.
This fixation of these two anatomic structures was performed with one Nylon Matress stitch for each of them (n = 16).
The mean age was between 40 - 70 years at surgery; the mean follow-up period was 1 year.
Clinical examination and Photographs were used to follow-up the patients.
The herniated fat pads were treated in all patients with using partial surgical excision or bipolar cauterizing, without using the repositioning technique, and without resuturing of lower incised septum (Table 1).
3. Results
The recurrence of lower eyelid pads occur in 4 patients in group 2, 4/15 (26.66%) patients:
· 1 patient unilateral.
· 3 patients bilateral.
There is no recurrence in the whole patient groups 1 + 3.
The recurrent fat pads in two patients were big, apparent, and have the same size before surgery.
In the other two patients the recurrent fat pads were moderate in size and appearance (Figure 3, Figure 4).
After more than 1 year of follow up no patients in groups 1 or 3 have any complaints about fat pad bulging relapse.
And the recurrence was determined by both the patient and the surgeon and according to previous pictures of the patient.
Recurrence patients requested another operation for fat pads more than 1 year sfter the first operation.

4. Discussion
Different problems can be encountered when planning a lower blepharoplasty, such as festoons, prominent fat bags, and a conspicuous transition from eyelid to cheek. Frequently, they occur simultaneously. In such cases, a larger amount of skin excision is needed to achieve an adequate correction. This carries an increased risk of eyelid retraction when dealing with hypotonic eyelids. Orbicularis muscle suspension can provide vertical support to the eyelid and so achieve a safer, more effective correction.
Several techniques have been reported to obtain this effect. We have found a laterally based transposition orbicularis flap to be a safe and effective method to transmit a controlled amount of traction to the lower lid [7].
In our study we have found that suspension of the orbicularis oculi muscle has also an important role in supporting the lower orbital septum and prevent the recurrence of the lower herniated fat pads.
And our results are familiar to another international study which includes the following.
While the incision of the orbicularis oculi muscle with lateral suspension of this muscle has been used by many authors to improve the tension of the lower eyelid [8] - [15]. They considered that the suspension of the orbicularis oculi muscle on the lateral orbital margin (with or without a true lateral canthus suspension) not only suspend the lower eyelid, but also improve the contour of the lower eyelid by redraping the skin and muscle, and by strengthening the orbital septum and consequently enhancing posterior placement of the herniated fat [16] [17] [18].
5. Conclusions
Suspension of the orbicularis oculi muscle in patients group 1 + 3 has a significant role in preventing recurrence of the herniated fat pads after upper and lower blepharoplasty.
This study suggests that the anchorage of the orbicularis muscle flap to the upper lateral orbital rim prevents the recurrence of the lower fat pads after blepharoplasty, independent of lateral canthopexy or plasty.
