Teardrop Breast Implants: Shape, Rotation and Textured-Shell Risk

Teardrop breast implants—also called anatomical or shaped implants—are fuller toward the bottom and narrower toward the top. That geometry can give a surgeon more control over breast height, width and the point of maximum projection. It does not guarantee a more “natural” result.

For a patient in the United States, the central tradeoff is not simply teardrop versus round. It is an oriented implant that must stay in position versus a round implant whose outline does not change when it rotates. Surface matters too: Mentor MemoryShape, a teardrop implant currently marketed in the U.S., has a textured shell. The FDA says the risk of breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is higher with textured implants than with smooth implants.

Teardrop versus round implants

“Teardrop,” “textured” and “gummy bear” are not interchangeable. Shape describes the outline, surface describes the shell, and cohesivity describes how firmly silicone gel holds together. A round implant can contain highly cohesive gel too. See Gummy Bear Implants: Form-Stable Silicone Breast Implants for more on these terms.

Do teardrop implants look more natural?

They may suit a particular anatomy or reconstructive plan, but available evidence does not establish that teardrop implants routinely produce a better-looking result.

In a randomized intraoperative comparison involving 75 augmentation patients, surgeons and lay reviewers found no aesthetic superiority for anatomical implants; surgeons also frequently failed to identify which shape had been used (study abstract). A prospective three-dimensional study of 10 patients found that implant size, rather than round versus anatomical shape, produced the significant change in breast topography (3D study).

The limited literature is not uniform. In a retrospective study, 14 patients exchanged one implant shape for the other while retaining the same volume and projection. Observers could distinguish the postoperative appearances, although the authors did not claim that either shape was superior (shape-exchange study).

These studies are small and use different methods. The practical point is that existing tissue, chest dimensions, implant volume and surgical technique can matter as much as—or more than—the label teardrop. A surgeon should explain what a shaped implant would accomplish in your specific case that a round implant of comparable dimensions would not.

Rotation is the shape-specific complication

An anatomical implant has a top and bottom. If it turns in its pocket, the fuller portion can move sideways or upward and visibly change the breast shape. Correction may require another operation to reposition or replace the implant and, in some cases, revise the implant pocket.

The surface used to help a shaped implant maintain its orientation creates a separate safety question. The FDA says BIA-ALCL risk is higher with textured implants than with smooth implants. BIA-ALCL is an uncommon lymphoma of the immune system—not breast cancer—and is usually found in fluid or scar tissue around an implant (FDA BIA-ALCL guidance).

Texture is not one uniform category. In 2019, Allergan recalled its BIOCELL textured products, including the anatomically shaped Natrelle 410, after an FDA request based on their BIA-ALCL risk (FDA recall announcement). The FDA’s approved-implant directory still lists historical approvals and places a recall note beside the affected Allergan products, so an approval listing should not be mistaken for current availability (FDA implant-labeling directory).

As of September 2026, Mentor’s U.S. website continues to market MemoryShape. The FDA describes it as a textured, highly cohesive silicone implant approved for augmentation in women 22 and older and for breast reconstruction (FDA device summary). Local availability may vary by surgeon and implant dimensions.

Recovery and long-term care

Teardrop shape alone does not determine recovery. Incision, implant size, pocket placement, and whether surgery includes a lift or capsule procedure also matter. The FDA says highly cohesive MemoryShape implants require a larger incision than saline or less-cohesive silicone implants (FDA device summary).

Pocket placement changes tissue coverage, discomfort and the possibility of implant movement with chest-muscle contraction. Compare those issues separately in Breast Implants Under vs Over Muscle.

No breast implant is a lifetime device. In the completed MemoryShape post-approval study, the estimated 10-year incidence of any reoperation was 22.3% in the primary-augmentation cohort. Only 60% of that cohort completed 10-year follow-up, and the study lacked a comparison group, so the estimate describes that product study rather than predicting one patient’s outcome (FDA post-approval study).

Silicone implants also need rupture surveillance. FDA labeling recommends a first ultrasound or MRI five to six years after surgery and every two to three years thereafter, even without symptoms (FDA labeling guidance). Include imaging and possible revision in the long-term budget, not just the initial quote. Our breast implant cost breakdown explains how to compare those expenses.

Questions to take to a consultation

Ask about the exact device rather than the general term “teardrop”:

1. What manufacturer, model, surface and dimensions are you proposing? Ask for the current patient labeling and decision checklist.
2. Why does this shaped implant fit my anatomy or reconstructive goal better than a round implant of comparable width and projection?
3. What product-specific BIA-ALCL information should I understand?
4. How often do you use this model, and how would you diagnose and correct rotation?
5. What incision and pocket position do you recommend, and why?
6. Does the quote include the implant, facility, anesthesia, follow-up and complication care?
7. Who arranges and pays for future ultrasound or MRI screening?
8. Will I receive a device card with the model and serial or lot information?

Persistent swelling, a new mass, pain or another late change around an implant warrants medical assessment, especially years after surgery. For people with no symptoms, the FDA does not recommend routine implant removal solely because an implant is textured; it advises monitoring for changes and discussing individual risk with a clinician (FDA guidance).

The useful decision is not whether teardrop implants are universally better. It is whether the contouring control of a specific shaped implant is valuable enough for your anatomy and goals to justify its rotation, surface, monitoring and revision tradeoffs.
