Artery Perforator Flap For Reconstruction Research Articles

Medial plantar artery flap

Background: The unique ability of the thick glabrous skin of the plantar heel to withstand body weight while also providing protective sensory feedback makes soft-tissue coverage of the plantar heel a particularly challenging aspect of foot reconstruction. In this study, we present the outcomes and complications associated with medial plantar artery perforator (MPAP) flap reconstruction of plantar heel. Methods: The study was a retrospective study conducted over four years, and included 22 patients with soft-tissue injury to the plantar heel. All patients underwent MPAP flap for coverage of the defect. We studied the mode of injury, defect size, flap size, duration of the procedure, complications associated with the flap and donor site, time to full weight bearing and return of protective sensation and 2-point discrimination in comparison with opposite heel. Results: We studied 22 cases with soft-tissue defects of the heel that included post-traumatic defects (7), non-healing diabetic ulcers (6), trophic ulcers (4) and post- tumor excision defects (melanoma-3, squamous cell carcinoma-2). Mean flap dimension was 24 sq.cm. 18 flaps had complete survival, while 2 flaps had necrosis of the distal edge and 2 flaps underwent complete necrosis.

Sequential posterior interosseous artery perforator flap for reconstruction of dorsal hand defects.

Dorsal hand defects accompanied by exposure of bones and tendons remain a huge challenge for plastic surgeons. The pedicled perforator flaps have unique advantages in resurfacing the defects. This study aimed to investigate the clinical efficacy of the sequential posterior interosseous artery perforator flap for repairing dorsal hand defects. This study was composed of an anatomical study and clinical application. Anatomically, 30 adult upper limb specimens injected with red latex were dissected, the perforators from the branches of the posterior interosseous artery were observed in the dorsal forearm, and the sequential flap based on them was designed based on the anatomical characteristics. Clinically, nine cases of soft tissue defects on the dorsum of the hand were treated by this flap. Anatomically, the posterior interosseous artery divided into an ascending branch and a descending branch, and the descending branch traveled 1.0 ± 0.3cm down to divide into the ulnar and radial terminal branches. The ulnar terminal branch presented constantly, and the radial terminal branch had an occurrence rate of 93.33%. Clinically, all flaps survived completely and possessed a soft texture and satisfactory appearance, as well as a nonbloated pedicle, and the donor region had a natural color and appearance with only a linear scar left behind. The sequential posterior interosseous artery perforator flap could become a useful option for repairing dorsal hand defects, as it has the advantages of being easy to perform without sacrificing the main vessels and avoiding donor area skin grafting.

Cost-volume analysis of deep inferior epigastric artery perforator flaps for breast reconstruction in the United States

BackgroundDeep inferior epigastric artery perforator flaps are increasingly utilized over other autologous methods of breast reconstruction. We evaluated the relationship between annual hospital volume and costs after breast reconstruction with the deep inferior epigastric artery perforator flap. MethodsAll female patients undergoing elective implant or autologous tissue breast reconstruction were identified using the 2016–2019 Nationwide Readmission Database. Annual hospital volume of deep inferior epigastric artery perforator reconstructions was tabulated and modeled using restricted cubic splines. Institutions were categorized into high- and low-volume based on the inflection point of the spline between annual caseload and costs. The association between high volume status and costs, complications, length of stay, and 30-day nonelective readmission was assessed using multivariable regression. ResultsOf an estimated 94,524 patients meeting inclusion criteria, 33,046 (34.6%) underwent deep inferior epigastric artery perforator flap reconstruction. Deep inferior epigastric artery perforator flap utilization increased from 31% in 2016 to 40% in 2019 (P < .001) among inpatient breast reconstructions. High-volume hospitals more frequently performed bilateral reconstructions (43.3 vs 37.7%, P = .021) but had similar rates of concurrent mastectomy (28.7 vs 30.6%, P = .46), relative to low-volume hospitals. The median cost of deep inferior epigastric artery perforator reconstruction was lower ($29,900 [interquartile range: 22,400–37,400] vs $31,600 [interquartile range: 22,500–44,900], P = .036) at high-volume hospitals compared to low-volume. On adjusted analysis, high-volume status was associated a $3,800 (95% confidence interval: -6,200 to -1,400) decrement in hospitalization costs, and reduced odds of perioperative complications (adjusted odd ratio: 0.68 95% confidence interval: 0.54–0.86). High-volume status was not associated with length of stay or likelihood of unplanned readmission. ConclusionThe present study demonstrated an inverse cost–volume relationship in deep inferior epigastric artery perforator flap breast reconstruction. In line with goals of value-based health care delivery, our findings may inform referral patterns to suitable centers for deep inferior epigastric artery perforator breast reconstruction.

A Single Superior Gluteal Artery Perforator Flap in Reconstruction of Large Midline Sacral Defects: A Method for Practical Harvest and Safe Closure.

Large midline sacral defects are reconstructive challenges. Superior gluteal artery perforator (SGAP) flap provides enough tissue and versatility to cover large defects; however, a single flap may be insufficient. We present a technique to cover large defects using single SGAP flaps. Large sacral defects (>100 cm2) reconstructed with single SGAP flaps were included. Angle of transposition (45°-60°) was determined based on the tissue laxity and mobility of gluteal area. Perforator identification, intramuscular dissection, or skeletonization was not performed. Outcomes were measured as achieving durable reconstruction, flap viability, and complications. There were 17 patients (12 male, 5 females; aged 25-72 years) with different etiologies. The mean flap surface area (136.1 ± 45.6 cm2, between 9 × 8 and 26 × 10 cm) was smaller than the mean defect surface area (211.1 ± 87.2 cm2, between 10 × 10 and 28 × 14 cm) (P < 0.001). All flaps survived with no partial or complete flap loss. Minor dehiscence in 4 patients (2 at donor site and 2 at recipient site) healed with dressing changes or using negative-pressure vacuum therapy. All patients had durable outcomes without any recurrence. Single unilateral SGAP flaps can be used to completely cover midline large sacral defects. It is important to design the flaps to have a joint side with the defect in the proximal part and use the intrinsic mobility of gluteal soft tissues for the closure. Flaps can be (1) planned to be smaller than the defects, (2) harvested with no intramuscular perforator dissection or pedicle skeletonization, and (3) transposed with an angle less than 60°.

Prognosis of Subcutaneous Mastectomy for Special Types of Breast Cancer.

Background and objectives: In the treatment of the special type of breast cancer (STBC), the choice of chemotherapeutic agents is often based on the characteristic features of the histological type. On the other hand, the surgical strategy is usually determined by the tumor size and presence of lymph node metastasis, and the indication for immediate reconstruction is rarely discussed based on the histological type. The prognoses of STBC and invasive ductal carcinoma of the breast (IDC) patients who underwent subcutaneous mastectomy (SCM) with immediate reconstruction at our institution were compared. Materials and Methods: A total of 254 patients with SCM with immediate reconstruction from 1998 to 2018 were included; their tumor diameter or induration was less than 25 mm, and it was not in close proximity to the skin. Preoperative chemotherapy and non-invasive cancer cases were excluded. Results: The number of patients was 166 for skin-sparing mastectomy (SSM) and 88 for nipple-sparing mastectomy (NSM). The reconstructive techniques were deep inferior epigastric artery perforator flap (DIEP) reconstruction in 43 cases, latissimus dorsi flap reconstruction (LDflap) in 63 cases, tissue expander (TE) in 117 cases, and transverse rectus abdominis myocutaneous flap/vertical rectus abdominis myocutaneous flap (TRAM/VRAM) reconstruction in 31 cases. The histological types of breast cancer were 211 IDC and 43 STBC; 17 were mucinous carcinoma (MUC), 17 were invasive lobular carcinoma (ILC), 6 were apocrine carcinoma, 1 was tubular carcinoma, and 2 were invasive micropapillary carcinoma. There was no difference in local recurrence or disease-free survival (LRFS, DFS) between IDC and STBC, and overall survival (OS) was significantly longer in STBC. OS was better in the STBC group because SCM with immediate reconstruction was performed for STBC, which is a histological type with a relatively good prognosis. Highly malignant histological types, such as squamous cell carcinoma or metaplastic carcinoma, were totally absent in this study. Conclusions: The indications for SCM with immediate reconstruction for relatively common STBCs such as MUC and ILC can be the same as for IDC.

Comparison Between Free Anterolateral Thigh Flap and Free Medial Sural Artery Perforator Flap in Reconstruction of Post Traumatic Soft Tissue Defects of the Dorsum of the Foot

Abstract Background: The objective of this study is to compare between the free anterolateral thigh flap and free medial sural artery perforator flap in reconstruction of post traumatic soft tissue defects of dorsum of the foot as regard the function, the aesthetic outcome, the complications and the patient satisfaction.Method: The study was conducted on 40 patients with post traumatic soft tissue defects of the dorsum of the foot between August 2018 and August 2019. Patients were allocated randomly into two groups. In group1 (20 patients), the defect was reconstructed with free anterolateral thigh perforator flap. In group 2 (20 patients), reconstruction was done by free medial sural artery perforator flap.Result: In group 1 (ALT flap), Complete flap survival was achieved in all cases. Thirteen patients required secondary debulking procedures and scar revisions.In group 2 (MSAP Flap), Complete flap survival was achieved in 17 cases with one flap totally lost and two flaps had distal necrosis. One patient needed scar revision and another patient needed flap advancement.Conclusion: MSAP flap is good alternative in soft tissue reconstruction of the dorsum of the foot. It has many advantages: it is thin, pliable, fitted to normal footwear, less hairy and there is no need for secondary procedures in most cases. ALT flap is better than MSAP flap in larger defects coverage but may need secondary debulking procedures or primary thinning at the time of reconstruction.

Ultrahigh-Resolution Computed Tomography Improves Preoperative Computed Tomography Angiography for Deep Inferior Epigastric Artery Perforator Flap Reconstruction.

The aim of the study was to compare computed tomography (CT) angiography (CTA) imaging of deep inferior epigastric artery perforator (DIEP) using the ultrahigh-resolution CT (UHRCT) and conventional multidetector CT (MDCT). This retrospective study enrolled 20 patients who underwent CTA of DIEP flap with UHRCT and MDCT. Computed tomography values were measured at 4 large vessels (thoracic aorta, abdominal aorta, common iliac artery, and external iliac artery) and 5 peripheral vessels (proximal and distal internal thoracic artery, proximal and distal deep inferior epigastric artery, and DIEP). There were no significant differences in mean CT values of the major vessel between UHRCT and MDCT. Ultrahigh-resolution CT shows higher CT values of the peripheral vessels than MDCT (P < 0.05 for all). The median CT values of the DIEP in UHRCT were approximately 3 times higher than those in MDCT (P < 0.001). Ultrahigh-resolution CT provides higher-quality CTA of DIEP compared with MDCT.

Comparison between Free Anterolateral Thigh Flap and Free Medial Sural Artery Perforator Flap in Reconstruction of Post Traumatic Soft Tissue Defects of Dorsum of the Foot

Background: The objective of this study was to compare the pliability, the function, aesthetic outcome, complications and patient satisfaction between free anterolateral thigh flap and free medial sural artery perforator flap in reconstruction of post traumatic soft tissue defects of dorsum of the foot. Method: The study was conducted on forty patients with post traumatic soft tissue defects of the dorsum of the foot between August 2018 and August 2019. Patients were divided randomly into two groups. In group1 (20 patients), the defects were reconstructed with free anterolateral thigh perforator flap. In group 2 (20 patients), reconstruction was done by free medial sural artery perforator flap. Result: In group 1 (ALT flap), Complete flap survival was achieved in 100% of cases. Thirteen patients required secondary debulking procedures and scar revisions. In group 2 (MSAP Flap), Complete flap survival was achieved in 85% with one flap totally lost and two flaps had distal necrosis. One patient needed scar revision and another patient needed flap advancement. Conclusion: MSAP flap is superior to ALT flap. It has many advantages: it is thin, pliable, fitted to normal footwear, less hairy and there is no need for secondary procedures in most cases.

Reconstruction of the First Web Space Using the Wide-Second Dorsal Metacarpal Artery Perforator Flap

Purpose: This study evaluated the functional and aesthetic outcomes of a wide-second dorsal metacarpal artery perforator flap for reconstruction of the first web space of the hand. This flap sets the proximal edge of the extensor retinaculum as the distal limit.Methods: We measured the preoperative and postoperative angles of the first web space and assessed the quality of the donor site scar in eight patients.Results: The average flap size was 5.5 × 2.8 cm (range, 5.0 × 1.5 cm to 5.0 × 6.0 cm), and all flaps survived completely. The mean postoperative angle was 53°. The mean Vancouver Scar Scale score of the donor site was 4 points, and the patients had near-normal thickness and vascularity values. There was no distortion of the scar, and patients were satisfied with the scar appearance of the donor site.Conclusion: The wide-second dorsal metacarpal artery perforator flap is a useful technique to reconstruct large defects of the first web space. It is easy to raise, thin, and pliable, and has excellent color and tissue matching.

Clinical Application of the Peroneal Artery Perforator Flap for Reconstruction of Lateral Malleolus Defects.

The reconstruction of defects of the lateral malleolus involving the exposed fibular bone or tendon is challenging. This study aimed to evaluate the clinical application of the peroneal artery perforator flap with or without split-thickness skin grafting for soft tissue reconstruction of the bony defect of the lateral malleolus of the ankle joints. Reconstruction using a peroneal artery perforator flap with or without split-thickness skin grafting was performed for 15 patients (10 men, 5 women) between January 2007 and December 2018. The mean age was 53.7 years, and the mean size of the flaps was 40 cm2. The flaps were elevated in the form of a perforator flap, and split-thickness skin grafting was performed over the flaps and adjoining raw areas. The flaps survived in all cases; however, partial necrosis was observed in 3 cases. In cases of small-sized defects of the lateral malleolus of the ankle joints where a flap is required for the exposed bone or tendon, reconstruction using the peroneal artery perforator flap is advantageous, since the morbidity rate of the donor site is low and soft tissue is reconstructed.

Superior epigastric artery perforator flap for reconstruction of deep sternal wound infection.

The treatment of deep wound sternal infection requires loco-regional pedicled flaps, usually with muscular flaps. Perforator propeller flaps represent the ultimate progress in the history of reconstructive surgery. We report here our experience with the superior epigastric artery perforator (SEAP) flaps to repair sternal defect. Six patients presenting deep sternal wounds infection were treated with SEAP propeller flap, between March 2015 and June 2017. The mean age was 71.5 (range 53-83) years. The mean length and width of the defect were 16.2 × 7 cm (ranging 8-20 × 4-10). An elliptical skin flap pedicled on the SEAP was harvested in the inframammary fold and rotated up to 90° to cover the defect. All SEAP flaps achieved a successful entire coverage of the defect. The mean size of the skin paddle of the flap was 20.2 × 7.3 cm (ranging 14-27 × 6-9). All flaps were able to provide a complete sternal wound cover. Venous congestion was present in five cases and adequately treated by leech therapy; necrosis was distal in one case, and interesting the entire superficial flap in two cases but with deep tissues remaining viable and able to cover the mediastinum: an infected flap required revision. Satisfyingly, at 2-years postoperative follow-up all-patients were alive with a successful mediastinal cover. The SEAP Perforator propeller flap is an alternative to muscle flaps to achieve treatment of deep and large sternal wound infection.

Reconstruction of soft tissue defects around the Achilles region with distally based extended peroneal artery perforator flap

IntroductionAchilles tendon rupture and soft tissue infections with wound dehiscence and tendon exposure following the tendon repair are not infrequent. Various procedures have been described for the reconstruction of soft tissue defects at the Achilles tendon region, yet there is lack of consensus on the ideal method. In this article we report our experience using the distally based peroneal artery perforator flap in reconstruction of combined defects of the Achilles tendon and overlying soft tissue. Methods7 patients with Achilles tendon injury and full-thickness soft tissue defects over the Achilles region underwent tendon repair and soft tissue reconstruction with the distally based peroneal artery perforator flap. Perforator vessels were identified at the septum between the peroneus longus and soleus muscles. After choosing the perforator with the largest diameter, meticulous deep dissection of the perforator was performed and completed 6 cm proximal to the lateral malleolus. The peroneal artery was transected and ligated and transposition of the flap to the defect was performed through a subcutaneous tunnel. ResultsThe size of the soft tissue defects and flaps ranged between 2×3 cm to 4×10 cm and 4×5 cm to 5×12 cm, respectively. Six out of 7 flaps survived completely without any complications. Post-operative venous congestion was observed in one patient which resulted in partial tip necrosis of the flap. The resulting wound healed with conservative treatment. Donor sites healed uneventfully in all patients. All flaps had excellent contour and provided stable soft tissue coverage. ConclusionDistally based peroneal artery perforator flap can be considered as a reliable alternative for the reconstruction of soft tissue defects around the Achilles tendon region. Advantages include (1) extended reach of the flap for the defects around the plantar and dorsal aspects of the foot, provided by the perforator dissection, (2) convenience with footwear and walking, provided by the skin texture similarity with the target region, (3) creating a protective surface to allow tendon gliding and prevent tissue adhesions after the tendon repair, provided by the crural fascia included in the flap, (4) obviating the need for microsurgical anastomosis and associated length of the operation.

Use of the superficial circumflex iliac artery perforator flap for reconstruction after sarcoma resection.

Postoperative complications after flap-coverage in sarcoma treatment can postpone postoperative adjunct treatments. Here, we present our experience with the use of the superficial circumflex iliac artery perforator (SCIP) flap after sarcoma resection. Patients undergoing immediate reconstruction surgery with a flap after sarcoma resection at a single institution from February 2017 to April 2020 were identified. Patient demographics, tumor characteristics, surgical characteristics, and complications were examined. Thirty-five consecutive patients underwent reconstructions using a SCIP flap (34 free and one pedicled SCIP flaps). We also identified 47 consecutive patients who underwent reconstruction with other pedicled or free flaps over the same time period. No significant differences were found in patient age, gender, defect size, or operative time between these two groups. The incidences of overall complications (20/47 [42.6%] vs. 3/35 [8.5%], p < .001), flap dehiscence (7/47 [14.8%] vs. 0/35 [0%], p = .018), and total flap complications (15/47 [31.9%] vs. 2/35 [5.7%], p = .005) were statistically greater in the control group than in the SCIP group. With its minimal postoperative complication rate both in the reconstruction site and the donor site, the SCIP flap can be considered an optimal reconstruction option after sarcoma resection.

Thin submental artery perforator flap for upper lip reconstruction: A case report

Reconstruction of upper lip defects can be challenging even for experienced surgeons. In order to restore both function and morphology, the use of quality soft tissue is essential. To this effect, the most common solution is the use of local flaps, or, in extreme situations, a free flap. However, a thin cutaneous upper lip defect may require a different approach. Perforator flaps are versatile and may allow an efficient reconstruction of soft tissue defects using adjacent similar tissues, providing the benefit of "like with like" coverage. We present the case of a 41-year-old female with a 1 × 1.5 cm basal cell carcinoma of the right-side upper lip, initially treated with a full thickness skin graft. Due to poor aesthetic and functional result, a thin submental artery perforator (SMAP) flap reconstruction was performed. Flaps' dimensions were 6 cm long and 4 cm wide and it was based on a perforator arising from the submental artery. Dissection was conducted above the platysma muscle, and the SMAP flap was transferred into the defect through a subcutaneous tunnel created below the mandible and posterior to the anterior belly of digastric muscle. The pedicle length of 6.5 cm was adequate for a tension free inset of the flap. Postoperative course was uneventful and the patient was discharged after 2 days. The 4-month follow-up showed a satisfying functional and aesthetic outcome with a concealed donor site scar. This report points out the coverage potential of the thin SMAP flap, which can be successfully used for a harmonious reconstruction in both color and texture of the upper lip.

Exploring the Lived Experience of Undergoing an Immediate Versus Delayed Deep Inferior Epigastric Artery Perforator (DIEP) Flap Reconstruction in Women Who Require Post-Mastectomy Radiotherapy

Introduction Post-mastectomy radiotherapy (PMRT) is recommended to women at high risk of local recurrence. There is a paucity of published work on the experience of women who undergo deep inferior epigastric perforator (DIEP) flap breast reconstruction in the context of requiring PMRT. The aim of the study was to explore and understand the patient experience of these women. Methods Purposive sampling was used to identify patients who had undergone an immediate reconstruction with PMRT and women who had undergone a delayed reconstruction after PMRT. Purposive sampling was used to identify and invite women to participate in the study. Semi-structured interviews were conducted using a grounded theory approach with a topic guide which was derived from relevant literature. Results Twenty women participated in the study. Ten women had undergone immediate reconstruction followed by PMRT and 10 women had undergone delayed reconstruction after PMRT. The results suggest that, regardless of the surgical pathway or the consequences of treatment, overall women were satisfied with the treatment decision they had made. Patients described the challenges around decision-making and their post-operative experience. However, patients were grateful to have had a breast reconstruction and in the most part happy with the treatment pathway they underwent. Conclusion The findings of this study suggest that women are motivated by a variety of factors when presented with the choice of immediate versus delayed breast reconstruction and can justify the treatment path they have taken. This study highlights the importance of discussing reconstruction options in terms of context of a person’s life and coping strategies. Patients appeared to use self-regulation in their behaviour to cope with their illness threat and decision-making. The women who chose delayed reconstruction were motivated by the delayed gratification of having a reconstruction that had not been subjected to PMRT.

Use of the Profunda Femoris Artery Perforator Flap for Reconstruction after Sarcoma Resection.

Background:Soft tissue sarcomas are rare neoplasms that can occur on any part of the body. The operative position for the resection is determined depending on the site of the soft tissue sarcomas; intraoperative repositioning may be needed for reconstruction. We present the profunda femoris artery perforator (PAP) flap harvest technique (wherein the flap can be used in any position), and suggest that the PAP flap transfer can eliminate the need for intraoperative repositioning.Methods:From December 2018 to January 2020, 7 patients with an average age of 68 years underwent reconstructions using a PAP flap after wide resection of STS. The mean defect size was 11.3 × 16.5 cm (range, 5.5–25 × 11–26 cm). The location of the defects was the medial thigh in 2 patients, the posterior thigh in 1, the popliteal fossa in 1, the groin in 1, and the buttock in 2. The PAP flap was elevated in the supine “frog-leg” position, the prone position, the jack-knife position, or the lateral “crisscross” position; the lateral decubitus position with the donor lower extremity on the bottom.Results:Of the 7 cases, the operations were performed in the supine “frog-leg” position in 3 cases, the prone position in 2 cases, the jack-knife position in 1 case, and the lateral “crisscross” position in 1 case. There were no intraoperative position changes in all cases. The mean size of the PAP flap was 8.7 × 19.9 cm (range, 6–11 × 17–24 cm). One patient had donor site dehiscence, which was treated conservatively. The PAP flaps survived completely in all cases. The mean follow-up period was 10.5 months (range, 6–17 months).Conclusion:Since the PAP flap elevation is feasible in every position, the PAP flap can be considered a versatile reconstruction option after sarcoma resection.

Superficial temporal artery perforator flaps for reconstruction of intraoral defects.

Intraoral defects after tumor resection are often reconstructed with free tissue transfer. However, in patients who are not good candidates for free tissue transfer, regional flaps based on the superficial temporal artery can be utilized. The authors present our technique to reconstruct intraoral defects with the superficial temporal artery perforator (STAP) flap and early outcomes. Five patients underwent STAP flaps for defects including the hard palate, buccal sulcus, floor of mouth, and retromolar trigone between 2017 and 2019. The mean defect size was 5.6 × 3.4 cm2 (3 × 3 cm2 - 7 × 4 cm2 ). The mean age was 74 (57-88) and all patients had recurrent cancer. External Doppler, indocyanine green laser angiography, and FLIR thermal imaging were used intra-operatively to identify the best perforators and plan for flap design. The mean flap size was 7.6 × 3.5 cm2 (6 × 3 cm2 - 10 × 5 cm2 ). Four flaps were based off of the posterior branch of the STA, while the fifth was based off of the anterior branch. Two donor sites were closed primarily, and three required skin grafts. One patient experienced partial flap necrosis. There were no complete flap losses and no donor site complications. Average follow up was 14.6 months (9-20 months). All patients maintained preoperative level of speech, mastication, and oral continence. The STAP flap can be based on the anterior or posterior branch of the superficial temporal artery and is a useful regional flap for intraoral defects after tumor resection.

Assessment of surgical outcomes and oncological safety for submental artery perforator flap reconstruction after ablation of oral cancer

The submental artery perforator flap (SAPF) has been a new option for the intraoral reconstruction of oral squamous cell carcinoma (OSCC) patients in recent years, but its surgical outcomes have not been well assessed. We compared the surgical outcomes and oncological safety of SAPF reconstruction for medium-sized soft-tissue defects after the ablation of primary oral cancer with traditional submental island flaps (SIF) and anterolateral thigh perforator flaps (ALTPF). Fifty-one SAPFs, 30 SIF, and 74 ALTPF were reviewed for the intraoral medium-sized reconstructions after the ablation of oral cancer from our institutional clinical oncological databases. We performed comparative assessments on the variables of surgical outcome and oncological safety among the 3 cohorts. A Kaplan-Meier estimate of survival for each flap was calculated. Operating time was significantly reduced in the SIF and SAPF groups than ALTPF (p = 0.021 and 0.014, respectively). Flap thickness of SAPF was the significantly thinnest (mean 0.5 cm) among three groups. The common complications of donor site for both SAPF and SIF group were incision dehiscence and orocutaneous fistula. There was no significant difference in disease-free survival (DFS) among the 3 groups. However, several OSCC patients with the SIF reconstruction were found to have recurrences with a metastatic lymph node under the flap after the first operation. SAPF could be a versatile choice of the intraoral reconstruction for the medium-sized soft-tissue defects after the ablation of oral cancer.
