Reconstruction of subtotal pharyngolaryngectomy using a fasciocutaneous free flap with cartilage graft: A case series of 17 patients.

INTRODUCTION: Subcricoid-hemilaryngopharyngectomy (SCHLP) with a reconstruction using a fasciocutaneous free flap armed with cartilage graft (FFACG) aims to avoid permanent tracheostomy while still maintaining the laryngopharyngeal functions. The purpose of this study is to report the outcome of this surgical approach. MATERIALS AND METHODS: Retrospective study including 17 men operated between 2001 and 2019. Specific survival rate included death caused by cancer or SCHLP complications. Complications, functional and oncological outcomes were evaluated retrospectively. RESULTS: There were no locoregional recurrences. One patient died due to inhalation pneumonia 3 years after surgery. Tracheostomy was closed in 13 patients (76.5%). Mean decannulation time was at six [1-14] months after surgery. CONCLUSION: SCHPL with FFACG could avoid total pharyngolaryngectomy with good oncologic results. However, tracheotomy is extended and deglutition recovery is long with high risk of aspirations. These complications justify that such surgery should be realized only on selected patients by experienced surgical teams. Expertise of the surgical team is critical.

Swallowing outcomes over time after total pharyngolaryngectomy and free flap reconstruction.

BACKGROUND: One of the challenges after total pharyngolaryngectomy (TPL) is to restore the swallowing function. The aim of this study was to compare swallowing outcomes between patients who underwent reconstruction with jejunum free flap (JFF) and other free flaps (OFFs). METHODS: This retrospective study included patients who underwent TPL and free flap reconstruction. The endpoints were the evolution of swallowing outcomes during the first five years after treatment assessed by the Functional Oral Intake Scale (FOIS), and outcomes associated with complications. RESULTS: One hundred and eleven patients were included, 84 patients in the JFF group and 27 in the OFF group. The patients in the OFF group experienced more chronic pharyngostoma (p = 0.001) and pharyngoesophageal stricture (p = 0.008). During the first year, a lower FOIS score tended to be associated with OFF (p = 0.137), and this result remained stable over time. CONCLUSIONS: This study suggests that JFF reconstruction provides better swallowing outcomes than OFF reconstruction, stable over time.

Outcomes of mandibular reconstruction using three-dimensional custom-made porous titanium prostheses.

BACKGROUND: Our aim was to report the long-term outcomes of mandibular reconstruction using CAD-CAM-designed 3D-printed porous titanium implants in patients not amenable to a free vascularized fibula flap reconstruction. METHODS: The implants were designed with ProPlan CMF® 2.2 software and manufactured with a Selective Laser Melting (SLM) "layer-by-layer" 3D-printing of pure porous titanium powder beds. Primary endpoints were implant exposure and implant removal calculated using Gray's tests. Secondary endpoints were predictive factors of implant exposure and implant removal, and rates of dental rehabilitation. RESULTS: Thirty-six patients were operated between 2015 and 2017 and were included in this study. Reconstruction using a porous titanium 3D-printed implant was proposed due to medical contraindication for a fibula free flap (n = 13), due to the failure of a previous fibula free flap reconstruction (n = 7), or due to refusal of a fibula free flap reconstruction by the patient (n = 16). The medical indications for mandibular reconstruction were a primary tumor requiring mandibulectomy in nine patients, mandibular osteoradionecrosis requiring mandibulectomy in nineteen patients, and secondary reconstruction in eight patients. The 2-year rates of implant exposure and implant removal were 69.4% and 52.8%. Reconstruction of the symphysis was a high-risk exposure variable (OR 30; p = 0.0003). Only one patient underwent a successful dental rehabilitation. CONCLUSION: The use of a porous titanium 3D- implant for mandibular reconstruction in head and neck cancer patients resulted in high rates of implant exposure and of implant removal, notably when symphysis involvement.

Hippocrates: father of mini-invasive nasal surgery.

Hippocrates, a Greek physician during the fifth century BC., is often considered the father of medicine. The Corpus Hippocraticum comprising of 58 volumes was writing between 450 and 150 BC. The objective of our study was to detail the management of nasal polyps during this period. We read and analyzed all volumes of the Corpus Hippocraticum in French translation and extracted all passages dealing with nasal polyps (n = 6). Surgical procedures in the Corpus Hippocraticum are described in great detail. The first surgical strategy for the removal of nasal polyps was by mini-invasive nasal approach: the lopping method and the sponge method. We explain the two mini-invasive nasal approaches with drawings. The meticulously detailed observations of the corpus give us a precious insight into the early perception of diseases, their progression and early attempts of treatment.

Use of the Novel Hourglass Shaping Sutures to Create a Natural Middle Vault Shape as Illustrated by Three-Dimensional Modeling.

SUMMARY: The middle vault plays a major aesthetic and functional role. Excessive narrowing of the middle vault can occur in the absence of appropriate middle vault reconstruction. This can result in both aesthetic flaws and functional issues. Spreader flaps combined with our hourglass shaping sutures technique yield a natural middle vault appearance and prevent unwanted functional and aesthetic complications.

Salvage total glossectomy and total glosso-laryngectomy: Are they worth it? A GETTEC French multicenter study.

BACKGROUND: Salvage total glossectomy (TG) or total glosso-laryngectomy (TGL) remain controversial, as highly morbid procedures. The objective was to describe oncological and functional outcomes after salvage TG or TGL. METHODS: We performed a multicenter retrospective study, including patients with previous neck irradiation undergoing TG or TGL for squamous cell carcinoma involving the base of tongue. RESULTS: We included 42 patients: 27 in the TG group and 15 in the TGL group. For the entire cohort, median OS and DFS were estimated at 19 months (95% IC [14-44]) and 10 months (95% IC [7-13]) respectively, with no difference between the two groups. After a median follow-up of 90 months, 10 patients (24%) were alive and free of disease. Att he end of follow-up, we noted a gastrostomy dependency of 89% and 87 %respectively in the TG and TGL group, and 48% of patients in the TG group had a tracheotomy. CONCLUSION: Although local control is difficult to achieve after salvage TG or TGL, these procedures are associated with acceptable survival and chance of cure for a last-resort situation. TG and TGL can be proposed in selected motivated patients after careful shared decision-making.

Delto-acromial artery perforator flap combined with a radial forearm free flap as a "vascular bridge" for nasal reconstruction.

Nasal reconstruction for total rhinectomy is challenging, especially if locoregional flaps are unavailable. Herein, we report the case of a nasal reconstruction combining a forearm free flap as "vascular bridge" and a Delto-Acromial Artery Perforator (DAAP) flap in its free form. The forearm free flap was used to restore missing elements of the nasal lining while the distal part of the radial pedicle has served as a donor vessel for the DAAP free flap which restores the nasal covering. A chondrocostal graft was used as a nasal framework. The nasal aspect at 24 months postop support the patient's satisfaction. The main advantages of the DAAP Flap are the pliability, relative hairless nature, skin thinness and its geographical proximity with the nose avoiding major dyschromia. Moreover, the anatomy consistency makes it easier to harvest, the underlying muscles are respected, and it allows for tension free primary closure without shoulder movement limitation.

Vestibuloplasty for immediate dental implantation in fibular free flap for oral cancer patients undergoing mandibulectomy reconstruction: A technical note.

Vestibuloplasty is fundamental to restore an oral vestibule for immediate dental implantation in fibular free flap (FFF) for oral cancer patients undergoing mandibulectomy reconstruction. Double surgical team including reconstructive head and neck surgeon and a dental surgeon is fundamental. The first step of the vestibuloplasty is to identify the skin perforator. The second step is to thin the FFF skin island as much as necessary to facilitate: i-the reinset into the gingivobuccal sulcus while creating enough space in the oral vestibule for the future dental prosthesis and ii-the exposition of dental implants. The third step is to create a percutaneous access to the implants through the FFF skin paddle using a dermatologic punch while preserving a large oral vestibule. The fourth step is the skin reinsertion into the gingivobuccal sulcus and closure. Realizing vestibuloplasty before radiotherapy allows prevention of soft tissue contraction and osteoradionecrosis while reducing the necessary time for a complete dental rehabilitation and improving patient quality of life.

18F-FDG PET/CT for early response assessment of jaw osteoradionecrosis after the PENTOCLO protocol: A promising imaging modality.

INTRODUCTION: The Pentoxifylline, Tocopherol and Clodronate protocol (PENTOCLO) showed promising results for jaw osteoradionecrosis (ORN) management. However, the clinical and radiological improvements are often delayed, leading to unwanted long-term treatment, with potential loss of opportunity for more radical surgical treatments. Our objective was to assess the diagnosis performance of 18F-FDG PET/CT to early predict ORN response to the PENTOCLO protocol. MATERIALS AND METHODS: All patients from our center who were treated with the PENTOCLO protocol and with a 18F-FDG PET/CT performed at diagnosis and three months after the end of antibiotherapy were retrospectively included. The PENTOCLO protocol was always combined with prior appropriate antibiotherapy for six weeks. The healing endpoint was divided into healing, stability or worsening, according to the combination of clinical and radiological assessments at the date of last follow-up. For each patient, the difference between the maximal standardized uptake value (ΔSUVmax) of the ORN lesion at three months and baseline were computed. Diagnostic performance of 18F-FDG PET/CT was evaluated by sensitivity, specificity and the area under the receiver operating characteristic curve (ROC-AUC) of ΔSUVmax. RESULTS: 24 patients were included with an average follow-up of 29.3 months. The healing, stability and worsening rate were 25%, 62.5% and 12.5% respectively. The AUC for discriminating worsening vs stability or healing was 0.92 (IC95 [0.81-1.00]). A ΔSUVmax greater than or equal to 0 was predictive of a worsening with a sensitivity and specificity of 84 and 66% respectively. CONCLUSION: 18F-FDG PET/CT imaging could be useful for early prediction of PENTOCLO treatment resistance with appropriate antibiotherapy.

A twostep supraclavicular flap method in head and neck reconstruction for refractory osteoradionecrosis.

Techniques of reconstructive surgery of the head and neck region have existed since Antiquity, with the pedicled forehead flap of Susruta as a reference. These methods are constantly evolving, with the introduction of free flaps in the 1980s, and more recently new technologies such as CAD-CAM. However, the surgical management of patients treated by radiotherapy for upper airway cancers remains a challenge in terms of functional and aesthetic results. Indeed, cervical irradiation, which alters the quality of skin and vascular tissue, jeopardizes good healing after head and neck reconstructive surgery. In this article, the authors proposed to revisit the standard technique of the pedicled supraclavicular flap. Flap design inspired from the known and described technique of the two-stage forehead flap, for the management of a fragile patient with refractory mandibular osteoradionecrosis.

Indications and Clinical Outcomes of Transoral Robotic Surgery and Free Flap Reconstruction.

We reviewed the indications, peroperative feasibility, and postoperative clinical outcomes of our first 50 consecutive patients who underwent free flap reconstruction after TORS for complex pharyngeal defects at our institution. We analyzed indications according to previous radiotherapy, the size of the resection, and the transoral exposure of critical structures. We reviewed surgical data, postoperative complications, and functional outcomes comprising tracheostomy and alimentation management. Indications were upfront surgery (34%), a second primary surgery after radiotherapy (28%), or salvage surgery after chemoradiotherapy failure (38%). Localizations were the tongue base (44%), tonsillar fossa (28%), pharyngeal wall (22%), and soft palate (6%). T-classifications were T1 (6%), T2 (52%), T3 (20%), and T4 (22%). The mean length of the surgery was 574 min. Two patients were intraoperatively converted to a conventional approach at the beginning of the learning curve. In conclusion, TORS and free flap reconstruction in complex situations were associated with low rates of postoperative complications and satisfactory functional outcomes. They were, however, associated with a renewed learning curve.

Thoracodorsal artery perforator free flap with vascularized thoracodorsal nerve for head and neck reconstruction following radical parotidectomy with facial nerve sacrifice: Step-by-step surgical technique video.

Oncological surgery of the parotid region sometimes requires the sacrifice of the facial nerve (parotid cancers, extensive skin cancers of the face, soft tissue sarcomas). The sacrificed portion of nerve can be reconstructed by a vascularized nerve graft, especially if the patient must undergo radiotherapy after surgery. In those cases, the facial nerve sacrifice is associated to an important loss of substance from the parotid region (skin, masseter, parotid, and sometimes jaw). Chimeric flap permit the reconstruction at the same time of the external skin, soft tissues for the volume (fat or muscle), nerve, and bone (ramus and angular part of the mandible). An other option was to raise two flaps but it increased the risk of failure (time of surgery, number of anastomosis, etc.). Reconstruction with a chimeric flap appears to be an ideal choice. Based on these observations, we offer our patients at the Gustave Roussy Institute (Villejuif, France) a thoracodorsal artery perforator (TDAP) free flap including the motor nerve of the latissimus dorsi and vascularized by the thoraco-dorsal pedicle, thus allowing reconstruction in a single surgery. The surgical technique is explained with a step-by-step video. Functional outcomes are also shown in the video. The TDAP or chimeric scapulo-dorsal flap with vascularized nerve has many advantages in the facial reanimation of patients suffering from parotid region cancers. This video article explains surgical steps for other teams.

Cancer surgery during the COVID-19 pandemic: The experience of a comprehensive cancer center performing preoperative screening by RT-PCR and chest CT scan.

BACKGROUND AND OBJECTIVES: During the worldwide pandemic of coronavirus disease 2019 (COVID-19), oncological procedures considered to be urgent could not be delayed, and a specific procedure was required to continue surgical activity. The objective was to assess the efficacy of our preoperative screening algorithm. METHODS: This observational retrospective study was performed between the 25th of March and the 12th of May 2020 in a comprehensive cancer center in France. Patients undergoing elective oncologic surgery were tested by preoperative nasopharyngeal reverse-transcription polymerase chain reaction (RT-PCR) that could be associated with a chest computerized tomography (CT) scan. RESULTS: Of the 510 screening tests (in 477 patients), only 5% (15/477) were positive for COVID-19 in 24 patients (18 RT-PCR+ and 7 CT scan+/RT-PCR-). Four patients were ultimately false positives based on the CT scan. In total, only 4.2% (20/477) of the patients were COVID-19+. The positivity rate decreased with time after the containment measures were implemented (from 7.4% to 0.8%). In the COVID-19+ group, 20% of the patients had postoperative pulmonary complications, whereas this was the case for 5% of the patients in the COVID-19 group. CONCLUSIONS: Maintaining secure surgical activity is achievable and paramount in oncology care, even during the COVID-19 pandemic, with appropriate screening based on preoperative RT-PCR.

Powered Rhinoplasty: A Simple Step-by-Step Approach.

SUMMARY: Reduction of a nasal hump and nasal base narrowing are very common steps during a primary rhinoplasty procedure. The greatest difficulty is to obtain stable fracture lines, a natural appearance, beautiful dorsal aesthetic lines, and the absence of palpable or visible irregularities, especially in the long term. The surgeon strives for a reproducible technique, which seems to be more feasible with mechanical osteotomies (powered or piezoelectric) than with traditional manual osteotomies. The aim of this article is to describe powered osteotomy in a step-by-step fashion to provide a clear guideline for rhinoplasty surgeons.

Reconstruction of Extensive Composite Parotid Region Oncologic Defects with Immediate Facial Nerve Reconstruction Using a Chimeric Scapulodorsal Vascularized Nerve Free Flap.

BACKGROUND: Cancer involving the parotid gland region may originates from parotid parenchyma itself or from locoregional organs and in rare cases, the facial nerve (FN) has to be sacrificed during tumor resection. In these cases, cancer extension often goes beyond the parotid compartment and requires extensive local resection responsible for complex multitissular defects. The goals of reconstruction may be summarized in the following two components: (1) restoration of the volumetric tissue defect and (2) FN reconstruction. The aim of this study is to describe our surgical technique and our cosmetic results using the chimeric scapulodorsal vascularized nerve (SDVN) flap to reconstruct extensive maxillofacial defects associated with FN sacrifice. METHODS: All patients undergone an extensive maxillofacial resection with FN sacrifice and primarily reconstructed with a SDVN flap were included. We classified the maxillofacial defects into six groups based on the type of resection. Intraoperative data including flap composition, topography of FN injury, length of nerve gap, and number of nervous anastomosis were recorded. RESULTS: Twenty-nine patients were included. Mean follow-up was 38.7 months. The harvested flaps included the SDVN combined with different components according to the defect group. A satisfactory volumetric restoration was obtained in 93% of cases. The mean number of distal nervous anastomosis was 4.5. The length of the vascularized grafted nerve ranged from 7 to 10 cm. CONCLUSION: This is largest series presented in literature on primary FN reconstruction utilizing a vascularized nerve graft. We believe that the chimeric SDVN flap should be highly considered for these cases due to its versatility. The surgeon is able to use single donor site available soft and hard tissues components along with a vascular motor nerve graft, which offers a great length and number of distal branches, and easily matches with the extracranial FN trunk and its peripheral ramifications.
