Thumb-up modification of the radial forearm free flap in oral cavity reconstruction: a description of a surgical technique

<b>Introduction:</b> Head and neck surgeons face the challenge of achieving maximum patient benefit that includes simultaneously curing the cancer and preserving the function of the affected organ. This is particularly challenging in patients with oral cancer.<b>Aim:</b> The aim of this study was to present the ‘thumb-up’ modification of the radial forearm free flap (RFFF) paddle in the reconstruction of postoperative oral cavity defects.<b>Material and methods:</b> The fasciocutaneous paddle of the RFFF flap in the ‘thumb-up’ modification was designed to form a rectangle with a narrow thumb-like extension. A three-dimensional canopy-like structure was then created after the sides forming the indentation in the flap paddle were properly sutured.<b>Results:</b> The three-dimensional roof-like structure fits perfectly into the resected tumour site of the soft palate, tongue root, and oral vestibule. Another advantage of this technique is that there is less risk of compression of the flap pedicle and better control of the pedicle during reconstruction.<b>Conclusions and significance:</b> the ‘thumb-up’ modification of the RFFF appears to provide a satisfactory functional outcome, with better control of the flap pedicle during surgery in oral cavity reconstruction compared with the two-dimensional shape of the RFFF paddle.

Medial sural artery perforator free flap versus radial forearm free flap in oral cavity reconstruction and donor site morbidity.

Radial Forearm Free flap (RFFF) is widely used in head and neck reconstruction, yet its donor site defect remains a significant drawback. The Medial Sural Artery Perforator Free Flap (MSAPFF) is considered an alternative flap to RFFF. This study aims to comprehensively analyze their characteristics, outcomes, and their impact on patient quality of life. All patients who underwent oral cavity reconstruction using RFFF and MSAPFF between February 2017 and April 2023 were included in this study. Flap characteristics, outcomes and post-operative complications were recorded and compared. Subjective donor site morbidity, aesthetic and functional results, and quality of life were also analyzed. The study included 76 patients: 37 underwent reconstruction with RFFF, and 39 with MSAPFF. There was no significance difference between the RFFF and MSAPFF regarding the success rate (97.2% vs 97.4%), flap size (4.8 × 8.8 cm2 vs 5 × 9.8 cm2), hospital of stay (15.5 days vs 13.5 days) and recipient site complications (P > 0.05). However, MSAPFF showed larger flap thickness (P = 0.001), smaller arterial caliber (P = 0.008), shorter pedicle length (P = 0.001), and longer harvesting time (P < 0.001). No significant difference was observed between the pre-and postoperative ranges of wrist and ankle movements or in recipient site complications. MSAPFF showed a significant difference in donor site morbidity (P < 0.05). The MSAPFF is an excellent alternative to the RFFF for repairing oral cavity defects, with additional advantage of a well-hidden scar on the posterior calf, a larger flap thickness, accepted pedicle length and arterial caliber. However, one should consider the harvesting time and surgical skills required in comparison to the RFFF. The study highlights the importance of the MSAPFF as an alternative option for RFFF with less donor site morbidity and high success rate in oral cavity reconstruction and improved patient Quality of life after ablative surgery.

The Oncological Safety of Submental Flap Reconstruction in Head-and-Neck Cancers: An Extended Follow-up Study.

The oncological safety of a submental (SM) flap is thought to be controversial. The objective of our study was to validate our previous study regarding the oncological safety of SM flaps in oral cavity reconstruction. An electronic database was searched from 2015 to 2021 for all head-and-neck tumor patients, where reconstruction was performed using a SM flap. Eighty-eight oral cavity squamous cell carcinoma patients, among whom 71 were males (81.8%), with a mean age of 55.3 years (range: 25-79 years), were retrieved from the database. The sites of involvement were 37 buccal mucosa, 27 lower alveolus, and 24 tongues. The mean follow-up was 33.5 months. The SM flap reconstruction was done for 88 patients; 3 had complete loss of flap, 17 had incomplete loss/partial necrosis, and 68 patients had uneventful recovery of the flap. We had 16 patients with local recurrence. Of these, 4 (4.5%) patients had clear margins and no lymphadenopathy at the level I at the final histopathology report. This study provides validation of the oncological safety of the SM flap and establishes that nodal positivity at level I alone does not contribute to recurrence at the primary site.

Utility of local flaps in the reconstruction of oncologic resection defects of the oral cavity

&lt;p class="abstract"&gt;&lt;strong&gt;Background:&lt;/strong&gt; Objectives of the study were: to report on the utility of local flaps for oral cavity reconstruction in patients undergoing radical surgery for oral cavity cancers, to enumerate different local flaps used for oral cavity reconstruction, and to assess survival and sequelae associated with various flaps.&lt;/p&gt;&lt;p class="abstract"&gt;&lt;strong&gt;Methods:&lt;/strong&gt; The study is a retrospective analysis of data on patients with oral cancer treated with resection and local flap reconstruction between January 2018 to February 2021. The study includes patients treated at a tertiary care cancer hospital in South India. Patients of oral cancer who underwent resection followed by local flap reconstruction between January 2018 to February 2021 were included. Data was analysed for the extent of resection and type of flap used. Details of flap outcomes in the form of major and minor flap loss, functional outcomes and sequelae if any, were documented. &lt;/p&gt;&lt;p class="abstract"&gt;&lt;strong&gt;Results:&lt;/strong&gt; 46 patients, 15 women and 31 men, were included in our series. The median age was 51.5 years with an interquartile range (IQR) of 20.5. Tongue was the most common subsite (n=26; 56.5%) followed by buccal mucosa (n=7; 15.2%). Of the 46 flaps done, the most commonly employed flap was the facial artery myo-mucosal flap (FAMM flap) (n=27;58.6%) followed by the nasolabial flap (n=7;15.2%). There was no case of complete flap loss. Grade II trismus (n=5) was the main sequela observed in this study.&lt;/p&gt;&lt;p class="abstract"&gt;&lt;strong&gt;Conclusions:&lt;/strong&gt; Local flaps are a reliable option in oral cavity reconstruction post oncologic ablation.&lt;/p&gt;&lt;p class="abstract"&gt; &lt;/p&gt;

Posterior tibial artery flap versus radial forearm flap in oral cavity reconstruction and donor site morbidity

The repair of soft tissue defects after oral cavity cancer resection is challenging. The aim of this study was to compare the outcomes and donor site morbidity of the radial forearm free flap (RFF) and posterior tibial artery perforator flap (PTAF) for oral cavity reconstruction after cancer ablation. All patients who underwent oral cavity reconstruction with a RFF or PTAF between January 2017 and December 2019 were included retrospectively in this study. All flaps were harvested with a long adipofascial extension. The donor site defects were closed with a triangular full-thickness skin graft harvested adjacent to the flap. Flap outcomes and donor site complications were recorded and compared. The study included 145 patients; 30 underwent reconstruction with a RFF and 115 with a PTAF. No significant difference between the PTAF and RFF was observed concerning the flap survival rate (98.3% vs 96.7%), flap harvest time (53.39 vs 49.28 min), hospital stay (12.3 vs 15.2 days), or subjective functional and cosmetic outcomes. The PTAF showed a larger vascular calibre (P < 0.05), greater flap thickness (P = 0.002), and lower frequency of surgical site infection (P = 0.055) when compared to the RFF. No significant difference was observed between the pre- and postoperative ranges of ankle and wrist movements. The PTAF is an excellent alternative to the RFF for the repair of oral cavity defects, with the additional advantages of a well-hidden scar on the lower extremity, larger vascular calibre, and lower frequencies of postoperative donor site morbidities.

Functional outcomes in tongue reconstruction with myomucosal buccinator flaps

Buccal myomucosal local flaps in oral cavity reconstruction are a valid option for small-to-moderate defects. Nevertheless, few articles report about functional recovery. The purpose of the present analysis is to evaluate the impact of these flaps on function and quality of life. The study, retrospectively conducted on 36 patients who were surgically treated for tongue cancer between 2012 and 2018 at the Unit of Maxillo-Facial Surgery, Foundation IRCCS Casa Sollievo della Sofferenza, San Giovanni Rotondo (Italy), evaluates functional outcomes using the following 4 questionnaires: Performance Status Scale for Head and Neck Cancer Patients, M.D. Anderson Dysphagia Inventory, Speech Handicap Index, and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Head and Neck Module. All patients are able to eat soft or more solid foods, and most of them eat quietly in public. Although 50% of cases reported a certain degree of dysphagia, it does not impact self-esteem and social relationships. Only 20% of patients have severe problems with speech. However, more than half of the cases (65%) report oral problems. The collected data confirm the suitability of the myomucosal cheek flaps for tongue reconstruction. Most patients report a good functional recovery and satisfactory quality of life even if none of them has a recovery comparable to the presurgical state.

The supraclavicular artery island flap in oral cavity reconstruction

To evaluate the advantages and disadvantages of the SAI flap as an alternative for free flap in reconstruction of oral cavity defects.

Submental Artery Island Flap in Oral Cavity Reconstruction. An Observational, Retrospective Two-centre Study.

Introduction The submental flap provides an alternative technique in orofacial reconstruction, especially in situations in which free flaps are not available, or the patients are unfit. Objective To demonstrate the oncological safety and benefits of this flap in oral cavity reconstruction. Methods A total of 14 patients with oral cavity cancers, who underwent submental flap reconstruction from January 2016 to January 2018, were included in the study. Results There were 11 male and 3 female patients with a mean age of 66.7 ± 14 (Min: 52/Max: 91) years old. The most common primary tumor site was the mobile tongue in 12 (85.7%) patients. All of the patients underwent ipsilateral selective neck dissection after the flap was harvested. Flap partial necrosis was observed in one patient, and total necrosis in another one. The mean follow-up was of one year. Nonlocal or regional recurrences were observed. Conclusion Submental island flap represents a good option in oral cavity reconstruction in a restricted setting or in patients considered not fit for free flap reconstruction. Preoperative selection of clinically neck node-negative patients is essential due to the potential risk of occult metastasis.

Functional Outcomes of the Medial Sural Artery Perforator Flap in Oral Cavity Reconstruction.

The medial sural artery perforator (MSAP) flap is an ideal option for reconstruction of oral cavity defects owing to its thin and pliable nature and favorable donor site. Our study presents an assessment of functional outcomes including speech and swallowing in patients with oral cavity tumors reconstructed with MSAP flaps. Patients undergoing MSAP reconstruction for oral cavity tumors between January 2014 and January 2018 were identified from our prospective head and neck cancer database. Functional outcomes were assessed in conjunction with the Speech and Language Team with a minimum follow-up of 6 months. Function (speech and swallowing) was recorded as a performance status scale set up by the assessing health care professional. A total of 38 patients underwent reconstruction with the MSAP flap over the study period. The patient cohort included 10 female patients and 28 male patients. The age range was from 30 to 78 years, with a mean age of 56.8 years. Complications included 1 flap loss and 1 donor site wound dehiscence.Most patients (84.2%) had intelligible speech at 6-month follow-up and further improvement at 1 year (92.1%). All patients resumed feeding on postoperative day 4, and only 7.8% (n = 3) of the patients required assistance with feeding at 1-year follow-up. The MSAP flap provides adequate small-volume replacement for oral cavity reconstructions. Our results indicate that most patients achieve a full diet with no restrictions by 1 year after reconstruction. Most of our patients demonstrated excellent speech with little or no need for repetition in conversation. Over the past few years, this has become the flap of choice for oral cavity reconstruction in our unit.

Utility of the lateral arm free flap in oral cavity reconstruction: a single-centre experience with Chinese patients

The lateral arm flap (LAF) may offer an alternative option for oral cavity repair. Twenty-five Chinese patients with oral cavity defects were reconstructed with a LAF. The anatomical characteristics of the flap, the donor site complications, and the functional and aesthetic assessments of recipient site were reviewed. The overall flap survival was 96.0% (24/25patients). The average pedicle length was 7.07±1.09cm when it was cut off at the insert of the deltoid, with an average arterial diameter of 1.30±0.37mm and vein diameter of 2.06±0.48mm. The average flap length was 7.06±1.01cm, and the average flap breadth was 5.28±0.66cm, with the average flap size ranging from 18 to 42cm2. One to three reliable perforators supplied the flap, with the proximal, middle, and distal perforators being located at 9.9±1.1cm, 8.6±1.4cm, and 5.7±1.2cm from the lateral epicondyle, respectively. The donor defect was closed primarily and healed uneventfully. A longitudinal scar was the most common morbidity of the donor site. The function and shape of the reconstructed tissues were well restored. The LAF provides a reliable choice for reconstructing medium-sized oral cavity defects, with minimal donor-site morbidity and ideally functional and aesthetic rehabilitation of the recipient site.

Long-Term Patient-Reported Outcomes of Radial Forearm Free Flap Donor Site in the Context of Head and Neck Cancer Reconstruction.

Radial forearm free flap (RAFF) is the workhorse flap for oral cavity reconstruction. In the context of oncological reconstruction with radial forearm flap, the patient-reported outcomes of donor site morbidity amongst Indian patients have not been reported previously. Cultural and racial differences prevent extrapolation of morbidity data from Western literature. We aimed to evaluate subjectively the subjective long-term functional and aesthetic outcomes of the RAFF donor site. Patients who underwent RAFF reconstruction for intra-oral defects between 2014 and 2016 were included. Two questionnaires (Cosmesis and Sensibility and Forearm Disability) were administered. Fifty-two patients who completed a 2-year follow-up were identified. Thirty-five patients (67%) had complaints regarding the donor site. With regard to cosmesis and sensibility, hand numbness was seen in 21 (40.4%) patients. With regard to forearm disability, a problem in lifting heavy weights was seen in 22 (42.3%) patients. Only three patients in the entire cohort had complaints regarding the cosmesis of the forearm scar. Overall disability score was low (7.83). With regard to donor site morbidity, numbness and difficulty in lifting weights was the most common complaint. There is good acceptance of the donor site and scar with minimum morbidity. These findings are useful for the preoperative counselling of the patients. This is the first Indian study evaluating the long-term subjective outcomes of the radial forearm donor site. We believe the RAFF is still the most preferred flap for oral reconstruction.

Submental flap practice patterns and perceived outcomes: A survey of 212 AHNS surgeons.

To describe American Head and Neck Society (AHNS) surgeon submental flap (SMF) practice patterns and to evaluate variables associated with SMF complications. The design is a cross-sectional study. An online survey was distributed to 782 AHNS surgeons between 11/11/16 and 12/31/16. Surgeon demographics, training, practice patterns and techniques were characterized and evaluated for associations with frequency of SMF complications. Among 212 AHNS surgeons, 108 (50.9%) reported performing SMFs, of whom 86 provided complete responses. Most surgeons who performed the SMF routinely reconstructed oral cavity defects with the flap (86.1%, n = 74). Thirty-seven surgeons (43.0%) experienced "very few" complications with the SMF. Surgeons who practiced in the United States versus internationally (p = 0.003), performed more total career SMFs (p = 0.02), and routinely reconstructed parotid and oropharyngeal defects (p = 0.04 and p < 0.001) with SMFs were more frequently perceived to have "very few" complications. SMF surgeons reported more perceived complications with the SMF compared to pectoralis major (p = 0.001) and radial forearm free flaps (p = 0.01). However, similar perceived complications were reported between all three flaps when surgeons performed >30 SMF. Among 94 surgeons not performing SMFs, 71.3% had interest in a SMF training course. Practice patterns of surgeons performing SMFs are diverse, although most use the flap for oral cavity reconstruction. While 43% of surgeons performing the SMF reported "very few" complications, overall complication rates with the SMF were higher compared to other flaps, potentially due to limited experience with the SMF. Increased training opportunities in SMF harvest and inset are indicated.

A comparative study between submandibular-facial artery island flaps (including perforator flap) and submental artery perforator flap: A novel flap in oral cavity reconstruction

ObjectiveThe purpose of this study was to introduce submandibular-facial artery island flaps (S-FAIF), including the perforator flap, and to evaluate their application for intraoral reconstruction in comparison with submental artery perforator flaps (SMAPF). MethodsNinety-six patients who underwent intraoral reconstruction using an S-FAIF (n = 34) or SMAPF (n = 62) after cancer resection were recruited in this study. The flap characteristics (viz., pedicle length, flap size, venous drainage pattern, and harvest time), short-term outcomes (viz., flap partial loss, intraoral wound dehiscence, fistula, and wound infection), and long-term morbidity (viz., facial nerve palsy, neck motion restriction, and hair growth) were compared. ResultsNine S-FAIFs were authentic perforator flaps pedicled by level Ⅰ facial artery perforators, while the rest were island flaps based on level Ⅱ facial artery perforators. The survival rates of S-FAIF and SMAPF were both 100 percent. Flap partial loss occurred in two patients in each group. The pedicle length of S-FAIF was shorter than that of SMAPF (p < 0.001). Statistics analysis revealed no significant difference regarding flap size, venous drainage pattern, short-term outcomes, neck motion restriction, or facial nerve palsy between the groups. S-FAIF required less harvest time (p < 0.001) and experienced less hair growth when compared to SMAPF (p = 0.011). ConclusionsThe S-FAIF is a robust and reliable novel flap and on par with SMAPF for reconstruction of small and medium-sized intraoral defects. It is preferred to SMAPF when technical requirements for flap harvest and hair problems are considered. It should be supplemented to the armamentarium for intraoral reconstruction.

Anatomical study and clinical application of medial sural artery perforator flap for oral cavity reconstruction

The present study aims to provide anatomical evidence for clinical application of the medial sural artery perforator (MSAP) flap. The current study investigated the vascular anatomy of the flap, evaluated the postoperative appearance and function of the donor and recipient sites, and investigate the clinical value in reconstruction of oral cavity. Six lower limbs of Chinese adult cadavers were microsurgically dissected. The locations and courses of the medial sural artery perforators were identified and recorded, which provided an anatomical basis for clinical application. Then, 16 clinical cases employing this flap were evaluated, ranging from 3×4cm to 6×8cm, and were employed for defects in the oral cavity region. Sixteen clinical cases with intraoral soft tissue defects, which included four clinical cases with inner cheek defects, were successfully followed up for 10–47 months (24 months on average). The donor site function, contour of recipient site and oral function recovery were evaluated as acceptable or better in cases with intraoral soft tissue defect, which were further verifying the value of clinical application of MSAP in repairing oral cavity defects. Moreover, two typical clinical cases were described in detail. To conclude, the MSAP flap is a favorable choice for small- to medium-size defects based on minor donor site morbidity, satisfactory oral function recovery, perforator stability and adaptation of the pedicle for anastomosis in the oral cavity region.

Bozola Flap for Oral Cavity Reconstruction in Patients with Tongue Cancer

Bozola Flap for Oral Cavity Reconstruction in Patients with Tongue Cancer

Use of medial upper arm free flap in oral cavity reconstruction: a preliminary study

The medial upper arm has previously been proposed as a potential free flap donor site, but the clinical application of such flaps in head and neck reconstruction has not been popular. The preliminary results of the clinical application of medial upper arm free flaps in oral cavity reconstruction are reported here. Five patients with oral cancer underwent surgical resection and neck dissection, with simultaneous reconstruction using a medial upper arm free flap. Functional outcomes were investigated using the University of Washington Quality of Life Questionnaire. Sensory-motor functions of the upper arm donor site were recorded before and after surgery. Four flaps were successfully transferred. One flap was abandoned during surgery because of a lack of perforators, and a forearm flap was used instead. All patients survived without loco-regional recurrence or distant metastasis. Functional outcomes, especially swallowing and speech, were satisfactory. The donor site scar was well hidden, with no functional impairment. This initial experience shows that the medial upper arm free flap represents an alternative perforator flap for oral cavity microsurgical reconstruction. The well-hidden scar and better texture match compared with other flaps make it suitable for oral cavity reconstruction.

Clinical application of submental artery perforator flap in oral and maxillofacial defect restoration after tumor resection

Objective: To summarize the clinical anatomical features and surgical technique of the submental artery perforator flap (SMAPF), and to evaluate the outcome and value of the flap for oral cavity reconstruction after cancer ablation. Methods: A total of 56 patients with oral cancer were included in this study. The modified SMAPF excluded the anterior belly of the digastric muscle and submental fatty tissue. The primary sites of malignancy were buccal mucosa (n=24), tongue (n=21), mandibular gingiva (n=6), mouth floor (n=3), soft palate (n=2). Results: The flap size varied from 3 cm×5 cm to 5 cm×12 cm. Four flaps presented mild venous congestion, which was salvaged with conservative measures such as acupuncture and blood letting. Overall flap survival rate was 100%. The SMAPF with septocutaneous perforator was used in 49 cases and with musculocutaneous perforator in seven cases. External jugular vein and internal jugular vein provides venous drainage were applied in half cases respectively. All the patients showed a good recovery of tongue mobility and mouth opening with a follow-up of 3-41 months. Local recurrence was detected in one patient 4 months after operation. Conclusions: The SMAPF is a reliable flap for oral cavity reconstruction with outstanding functional and aesthetic outcomes.

The Submental Island Flap in Head and Neck Cancer.

Objectives:The submental flap provides an alternative technique in orofacial reconstruction, especially in situations where free flap services are not available. The objective of this study is to demonstrate the oncological safety and benefits of this flap in oral cavity reconstruction in a tertiary care cancer hospital.Materials and Methods:A total of 27 patients with oral cavity cancers, which underwent submental flap reconstruction from 2015 to 2017 at Shaukat Khanum Cancer Memorial Hospital, were included in the study. We have retrospectively reviewed records of these patients.Results:There were 25 male and 2 female patients with age ranging from 21 to 73 years. Most common primary tumor sites were buccal mucosa (13), tongue (7), and lower alveolus (7). All patients underwent ipsilateral selective neck dissection after flap was harvested. Complete flap loss was observed in three, whereas one patient had flap dehiscence that subsequently healed. Mean follow-up was 11 months. There were four regional recurrences but no local recurrence. On the last follow-up (minimum 6 months), 15 patients were alive without any disease, 4 were alive with disease, and 3 had died.Conclusion:Submental flap is a satisfactory option for oral cavity reconstruction. However, preoperative selection of clinically neck node-negative patient is extremely important as it has potential risk of occult metastasis.

Cervicofacial-facial artery myocutaneous flap (C-FAM flap): A novel flap in oral cavity reconstruction.

Reconstruction is an integral part of the surgical management of oral cancer. Local flaps are one of the options in reconstruction of small to moderate sized defects of oral cavity. Reconstruction is an integral part of the surgical management of oral cancer. Every defect needs to be assessed individually to tailor made the reconstruction because of its multidimensionality and complexity. Varieties of autologous tissues are being used in reconstruction like local, regional, or free flaps which can be simple or complex tissues. There is always a trend to identify the newer flaps/technique to personalize reconstruction. Local flaps are also one of the options in reconstruction of small to moderate sized defects of oral cavity. Local tissue if it is available is in the primary surgeon's purview and the flap can be raised without much technical difficulty and morbidity. We used perforator based tissue from the face and neck which is richly supplied by the facial vessels and named as the Cervicofacial- Facial Artery Myocutaneous flap (C-FAM flap) for reconstruction of oral cavity. We used perforator based local tissue from the face and neck which is supplied by facial vessels and named it as the C-FAM flap for the reconstruction of oral cavity defects. Twenty-eight patients underwent C-FAM flap reconstruction in different subsites of the oral cavity with acceptable functional rehabilitation. There was no flap loss. The C-FAM flap is a robust flap, which is reliable, pliable, and rich in its vascularity. It has to be one of the armamentarium for the oral cavity reconstruction.
