A modified nasolabial flap technique successfully reconstructed large lip defects in 11 cancer patients, with 81.8% achieving normal speech and diet resumption within 4 to 6 weeks. According to Gram Research analysis, no flaps completely failed, and 81.8% had excellent or good aesthetic outcomes. While this small preliminary study shows promise as a single-stage alternative to complex microsurgery, larger comparative studies are needed to confirm safety and effectiveness.
When doctors remove lip cancer, they need to rebuild the lip so patients can eat, speak, and smile normally. Gram Research analysis of a new surgical technique shows that doctors can use a special flap of skin and tissue from near the nose to reconstruct large lip defects in a single surgery. In this study of 11 patients, 81.8% regained normal speech and could eat regular food within 4 to 6 weeks. While the technique is still new and needs more testing, early results suggest it could help patients recover better function and appearance after cancer surgery.
Key Statistics
A 2026 retrospective study of 11 patients found that 81.8% regained normal speech and could eat regular food within 4 to 6 weeks after nasolabial flap lip reconstruction surgery.
In a 2026 case series of 11 lip cancer patients undergoing nasolabial flap reconstruction, 81.8% achieved excellent or good aesthetic outcomes with no total flap loss.
A 2026 study of 11 patients showed that only 2 patients (18.2%) experienced minor tissue complications after nasolabial flap lip reconstruction, with no complete flap failure.
Among 11 patients in a 2026 study, 63.6% achieved full oral competence and normal mouth function after nasolabial flap reconstruction for large lip defects.
The Quick Take
- What they studied: A new way to rebuild lips after cancer surgery using a special flap of skin and tissue from the area between the nose and upper lip.
- Who participated: 11 patients (6 men and 5 women, average age 60) who had large lip cancers removed. Most had squamous cell carcinoma, a common type of skin cancer, and most needed lower lip reconstruction.
- Key finding: Nine out of 11 patients (81.8%) recovered normal speech and could eat regular food within 4 to 6 weeks. Nine patients also had excellent or good-looking results. Only 2 patients had minor tissue death, and no flaps completely failed.
- What it means for you: If you need lip reconstruction after cancer surgery, this technique may help you recover normal eating and speaking ability in one surgery. However, this is early research with a small group, so talk with your surgeon about whether it’s right for your situation.
The Research Details
Doctors reviewed the medical records of 11 patients who had undergone a specific type of lip reconstruction surgery between a certain time period. This is called a retrospective study, meaning researchers looked back at what already happened rather than following patients forward in time. The surgeons used a technique called a nasolabial flap, which takes a piece of skin, fat, and tissue from the area between the nose and upper lip and moves it to rebuild the lip. This flap includes both the outer skin layer and the inner lining of the mouth, allowing doctors to rebuild the entire thickness of the lip in one operation.
The researchers carefully documented how long surgery took, whether the flap survived, what complications happened, and how well patients could speak, eat, and smile after healing. They followed patients to see if their cancer came back and how satisfied they were with how their lip looked and worked. The study was small and looked only at what happened after the surgery, without comparing this technique to other methods.
This research matters because lip cancer surgery creates a real problem: doctors must remove the cancer but also restore the lip so patients can function normally. Previous methods often required multiple surgeries or complex microsurgery that not all hospitals can perform. By showing that this technique works well in one surgery with good results, it offers hope for patients and may be useful in hospitals without advanced microsurgery capabilities. Understanding which reconstruction methods work best helps surgeons choose the right approach for each patient.
This study has important limitations to understand. With only 11 patients, the results may not apply to everyone. The study looked backward at existing records rather than following patients forward, which can miss important details. There was no comparison group of patients who had different surgery types, so we cannot say this method is better than alternatives. The researchers were honest about these limits and called for larger studies to confirm the findings. The fact that no flaps completely failed and most patients regained normal function is encouraging, but larger research is needed before making strong claims.
What the Results Show
The surgery was successful in all 11 patients, with no complete flap failure. The average surgery took 202 minutes, with 73 minutes spent harvesting the flap from the donor site. Patients stayed in the hospital an average of 6 days. Most importantly, 9 out of 11 patients (81.8%) recovered normal speech, and 9 out of 11 (81.8%) could return to eating regular food within 4 to 6 weeks after surgery. Seven patients (63.6%) achieved full oral competence, meaning they could control food and saliva normally in their mouth.
Minor complications were manageable. Two patients (18.2%) experienced partial or superficial tissue death, meaning only the outer layers of the flap were affected, not the entire flap. Three patients (27.3%) had temporary venous congestion, which is swelling from blood backup that resolved on its own without additional treatment. These complications did not prevent good functional recovery.
Aesthetic outcomes, meaning how the lip looked, were excellent or good in 9 patients (81.8%). Only 2 patients experienced cancer recurrence during follow-up: one local recurrence at the original site and one in lymph nodes. This recurrence rate is comparable to what doctors see with other reconstruction methods and likely reflects the original cancer severity rather than the reconstruction technique.
Six patients required removal of lymph nodes in the neck because the cancer had spread. Two of these six patients had cancer cells in the lymph nodes, indicating more advanced disease. Four patients needed bone resection, meaning part of the jaw bone was removed along with the cancer. Despite these more complex cases, functional outcomes remained good, suggesting the technique works even for patients with more extensive disease. The fact that patients with bone resection still achieved good speech and eating ability is particularly encouraging.
The nasolabial flap is not new, but using it as a full-thickness flap (including both skin and inner mouth lining) in one stage is a modification of traditional techniques. Previous methods often required two stages or used free flaps, which require microsurgery expertise. This study shows that the modified technique achieves similar functional and aesthetic results to more complex methods. The 81.8% rate of normal speech and diet recovery is comparable to published results from free-flap reconstruction, but with potentially less surgical complexity. However, direct comparison studies are needed to confirm this.
The study included only 11 patients, which is a very small number. With such a small group, results may not apply to all patients with lip cancer. The study looked backward at medical records rather than following patients forward, which can miss important information. There was no control group of patients who had different surgery types, so we cannot say this method is better than alternatives. The study did not measure patient satisfaction or quality of life in detail. Follow-up time varied among patients, so long-term results are unclear. The researchers were honest about these limits and recommended larger comparative studies before widespread adoption.
The Bottom Line
If you have a large lip defect from cancer surgery, discuss this nasolabial flap technique with your surgeon as a possible option. The evidence shows good functional recovery and appearance in most patients. However, this is early research, so ask your surgeon about their experience with this specific technique and how it compares to other options available to you. The technique appears most useful when microsurgery is not available or when you want to avoid multiple surgeries. Confidence level: Moderate, based on early results from a small study.
This research matters most for people with large lip cancers requiring reconstruction, particularly in settings where advanced microsurgery is not available. Surgeons and cancer centers should be aware of this technique as an alternative to more complex methods. Patients who want single-stage reconstruction with good functional outcomes should discuss this option with their surgical team. This research is less relevant for small lip defects or patients with access to specialized microsurgery centers.
Most patients regained normal speech and eating ability within 4 to 6 weeks. Full healing and final aesthetic appearance typically take 3 to 6 months. Some patients may see continued improvement in appearance for up to a year as swelling decreases and scars mature. Talk with your surgeon about realistic timelines for your specific situation.
Frequently Asked Questions
What is a nasolabial flap and how does it work for lip reconstruction?
A nasolabial flap is a piece of skin, fat, and tissue taken from the area between your nose and upper lip and moved to rebuild your lip. It includes both the outer skin and inner mouth lining, allowing doctors to rebuild the entire lip thickness in one surgery without needing microsurgery.
How long does it take to recover normal eating and speaking after this lip surgery?
According to a 2026 study of 11 patients, most people regained normal speech and could eat regular food within 4 to 6 weeks. Full healing and final appearance typically take 3 to 6 months as swelling decreases.
What are the risks and complications of nasolabial flap lip reconstruction?
In a 2026 study of 11 patients, minor complications included partial tissue death in 18.2% and temporary swelling in 27.3%, both manageable without major problems. No flaps completely failed, and 81.8% had excellent or good results.
Is nasolabial flap reconstruction better than free flap surgery for lip cancer?
The 2026 study shows similar functional outcomes to free-flap surgery but with potentially simpler technique. However, no direct comparison study exists yet. Ask your surgeon which method is best for your specific situation and their experience level.
Can this technique work for very large lip defects involving bone removal?
Yes. In the 2026 study, 4 patients needed bone resection along with cancer removal, and they still achieved good speech and eating ability. The technique appears effective even for complex cases, though individual results vary.
Want to Apply This Research?
- Track daily speech clarity and eating ability using a simple 1-10 scale. Record what foods you can eat (soft, regular, hard) and any difficulty speaking or controlling saliva. Note this weekly for the first 8 weeks after surgery to monitor functional recovery.
- Start with soft foods immediately after surgery, then gradually progress to regular foods as tolerated. Practice speaking exercises as recommended by your surgeon or speech therapist. Set weekly goals to increase food texture or speaking duration. Use the app to log these milestones and share progress with your surgical team.
- Create a long-term tracking system that monitors lip appearance (using photos), function (speech and eating ability), and any signs of recurrence. Set monthly check-ins for the first year, then quarterly thereafter. Track any numbness, weakness, or changes in sensation. Share this data with your surgeon at follow-up appointments to ensure optimal recovery.
