RESUMEN

BACKGROUND: The KEYNOTE-048 trial showed that pembrolizumab-based first-line treatment for R/M HNSCC led to improved OS in the PD-L1 CPS ≥ 1 population when compared to the EXTREME regimen. However, the R/M HNSCC real-world population is generally frailer, often presenting with multiple comorbidities, worse performance status and older age than the population included in phase III clinical trials. METHODS: This is a retrospective, single-centre analysis of patients with R/M HNSCC treated with pembrolizumab-based first-line treatment. RESULTS: From February 2021 to March 2023, 92 patients were treated with pembrolizumab-based first-line treatment. Patients treated with pembrolizumab-based chemoimmunotherapy had better ECOG PS and younger age than those treated with pembrolizumab monotherapy. Median PFS and OS were 4 months and 8 months, respectively. PFS was similar among patients treated with pembrolizumab-based chemoimmunotherapy and pembrolizumab monotherapy, while patients treated with pembrolizumab monotherapy had worse OS (log-rank p =.001, HR 2.7). PFS and OS were improved in patients with PD-L1 CPS > = 20 (PFS: log-rank p =.005, HR 0.50; OS: log-rank p =.04, HR 0.57). Patients with higher ECOG PS scores had worse PFS and OS (PFS, log-rank p =.004; OS, log-rank p = 6e-04). In multivariable analysis, ECOG PS2 was associated with worse PFS and OS. CONCLUSIONS: PFS in our real-world cohort was similar to the KEYNOTE-048 reference while OS was numerically inferior. A deeper understanding of clinical variables that might affect survival outcomes of patients with R/M HNSCC beyond ECOG PS and PD-L1 CPS is urgently needed.

RESUMEN

PURPOSE: One of the most severe complications in surgery of parotid tumors is facial palsy. Imaging of the intra-parotid facial nerve is challenging due to small dimensions. Our aim was to assess, in patients with parotid tumors, the ability of high-resolution 3D double-echo steady-state sequence with water excitation (DE3D-WE) (1) to visualize the extracranial facial nerve and its tracts, (2) to evaluate their relationship to the parotid lesion and (3) to compare MRI and surgical findings. METHODS: A retrospective study was conducted including all patients with parotid tumors, who underwent MRI from April 2022 to December 2023. Two radiologists independently reviewed DE3D-WE images, assessing quality of visualization of the facial nerve bilaterally and localizing the nerve's divisions in relation to the tumor. MRI data were compared with surgical findings. RESULTS: Forty consecutive patients were included (M:F = 22:18; mean age 56.3 ± 17.4 years). DE3D-WE could excellently visualize the nerve main trunk and the temporofacial division in all cases. The cervicofacial branch was visible in 99% of cases and visibility was good. Distal divisions were displayed in 34% of cases with a higher visibility on the tumor side (p < 0.05). Interrater agreement was high (weighted kappa 0.94 ± 0.01 [95% CI 0.92-0.97]). Compared to surgery accuracy of MRI in localizing the nerve was 100% for the main trunk, 96% for the temporofacial and 89% for the cervicofacial branches. CONCLUSIONS: Facial nerve MR-neurography represents a reliable tool. DE3D-WE can play an important role in surgical planning of patients with parotid tumors, reducing the risk of nerve injury.

RESUMEN

INTRODUCTION: Skull base pathologies in the paediatric population are rare and require treatment by multiple qualified specialists. The endoscopic endonasal approach has revolutionized surgical treatment because it is less invasive than existing treatments.The goal of this study was to retrospectively review our experience with the reconstruction of paediatric skull middle base defects and associated complications. MATERIALS AND METHODS: We analysed medical records from patients aged ≤ 18 years who were treated at our centre between 2013 and 2021. Patients treated with an endoscopic skull base approach and reconstruction, and who had complete clinical and radiological documentation and a minimum follow-up of 12 months, were included in the analysis. Personal data, reconstructive techniques, and complications were analysed. RESULTS: A total of 78 patients met the inclusion criteria and were enrolled in the study. Of these patients, 32 were male and 46 were female, and the mean age was 11.5 years. The main signs and symptoms were as follows: bitemporal hemianopsia in 53 cases, visual impairment in 23 cases, and headache in 30 cases. The most frequent aetiologies were craniopharyngioma (38 cases), pituitary adenoma (23 cases), and clivus chordoma (4 cases). All patients were treated via a pure endoscopic approach. For reconstruction, a multilayer technique was used in 18 cases, naso-septal flap in 43 cases, Gasket-Seal technique in 12 cases, and heterologous reconstruction in 5 cases. Only six patients presented a major complication: two had a postoperative cerebral spinal fluid leak, one developed a brain abscess, and three had diabetes insipidus.The mean follow-up period was 23.4 months.There were no statistically significant differences in postoperative CSF leak in relation to different reconstructive techniques. CONCLUSION: Endoscopic endonasal skull base surgery is a safe and effective treatment for paediatric middle skull base pathologies. Reconstruction techniques have a high success rate of 96.5-100%, and the rate of associated complications is < 3%.

RESUMEN

Mandibular fractures are the second most common maxillofacial fractures. The prevalent treatment for this kind of fractures is either a surgical procedure such as maxillomandibular fixation or open reduction and internal fixation or a combination of both. Sometimes the patients might develop locoregional postoperative complications. The most frequently reported complications are trigeminal V3 injury and surgical site infection. A 4-year retrospective study was performed at the Department of Oral and Maxillofacial Surgery, Policlinico Umberto I of Rome, Italy, and the postoperative complications after mandibular fracture surgical treatment were collected. The authors studied the characteristics of each complication and the correlation with the type of mandibular fracture and the surgical treatment chosen.

RESUMEN

The main causes of injuries to the lower and middle third of the facial skeleton are traffic accidents, accidental falls, assaults, and sport. Regarding sports-related maxillofacial trauma, an 8-year retrospective study was conducted at the Department of Oral and Maxillofacial Surgery of the Policlinico Umberto I in Rome, Italy. In all, 329 patients were included, of which we analyzed 35 patients with sports-related mandibular fractures. Specifically, we assessed the type of mandibular fracture reported, age, gender, number of fracture lines, association with other maxillofacial fractures, and treatment options. The causes of sports-related injuries are often multifactorial. Therefore, the aim of our study was to understand the correlation between the type of sport practiced and the most frequently reported pattern of mandibular fracture, highlighting how, depending on the sport, the mechanism of action is different and may correlate with a specific type of mandibular fracture.

RESUMEN

Orbital fractures are among the most frequent facial injuries. Of the 3 most widely described approaches in the literature, the lower eyelid approach is the authors' preference. This study retrospectively analyzed the patients treated at the Trauma Center of the Umberto I Hospital, Sapienza University of Rome from January 2010 to December 2020. Inclusion criteria were as follows: diagnosis of pure/impure orbital bone fracture, complete clinical and radiological documentation, and a minimum of 12 months follow-up. Sex, age, etiology, treatment, and associated complications were analyzed using IBM SPSS Statistics. Two internationally validated scales were used for the functional and esthetic long-term evaluation: the Patient and Observer Scar Assessment Scale (POSAS) and the Vancouver one. The scales were compiled by the patient himself and by 3 independent expert observers. Of the 543 patients who underwent surgery in the specified period, 208 fully met the inclusion criteria. One hundred forty-two (68.2%) were males and 66 (31.8%) were females, with a mean age of 40.68 years. The main cause was represented by assaults (33.1%). One hundred seventy-nine patients had a pure orbital fracture (83.8%) and 29 an impure one (16.2%). The most frequent symptoms at the time of diagnosis were diplopia (31.2%), followed by anesthesia of the second trigeminal branch (24.3%). Open reduction with internal fixation was the preferred treatment and proved to be effective in reducing the main signs and symptoms of the fracture in a statistically significant way ( P < 0.05). Long-term esthetic results of the lower eyelid, using the Vancouver and POSASs, were respectively as follows: Vancouver Scar Scale mean total score was 2.41 (range: 0-8), observer POSAS mean total score was 1.83 (range: 1.2-3.9), observer general opinion mean score was 1.66, patient POSAS mean total score was 2.23 (range: 1.33-3.7), and patient general opinion mean score was 2.87. The lower eyelid approach has proven to be reproducible, with a fast-learning curve and a low complication rate. The analysis conducted highlighted an excellent long-term esthetic-functional result. Further studies will be needed to statistically compare the results obtained with other orbital floor surgical approaches.

RESUMEN

INTRODUCTION: Cavernous malformations of the ventral brainstem are a challenging disease to treat. From an anatomical perspective, the best surgical options are endoscopic endonasal approaches. The first reports of their usage for this purpose date back to 2012. In this study, we gathered data on the subject, share our experience, and outline technical notes and tips for this surgery. CASE PRESENTATION: We report a 14-year-old female with a ventral pons cavernoma, treated using an endoscopic endonasal transclival approach and followed-up for 5.9 years. This is the longest reported follow-up for this condition to date. Written informed consent was obtained from the patient for publication of this case report and the accompanying images. DISCUSSION: An endoscopic endonasal transclival approach was used. The skull base was reconstructed using the multilayer grafting technique and a nasoseptal flap. There was no postoperative cerebrospinal fluid leakage. In a literature review, we identified 8 patients who were treated endoscopically: 1 transplanum-transtuberculum, 1 transtuberculum-transclival, and 6 transclival approaches were employed. Skull base closure was achieved using multilayer grafting and a nasoseptal flap in 4 cases, a gasket seal technique combined with nasoseptal flap in 3 cases and a periumbilical fat graft, fibrin sealant patch, and fibrin glue in 1 case. There were 2 cases of leakage, which resolved completely with revision surgery. CONCLUSION: Endoscopic surgery is a reliable alternative to traditional open surgery. It may be the preferred choice for intra-axial ventral brain cavernomas.

RESUMEN

ABSTRACT: The authors sought correlations between harvesting of the scapular bone tip free flap used for head-and-neck reconstruction and any shoulder function deficit, particularly at the level of the rotator cuff. The flap permits reconstruction of large and diverse regions of the head and neck, but long-term harvest morbidity has not been investigated extensively. The authors analyzed the clinical records of all patients who underwent head-and-neck reconstructions using free scapular tip flaps in our department over the past 5 years. The inclusion criteria were complete clinical and radiological documentation and follow-up for at least 12 months. Two populations, a surgical and control population, were analyzed. All patients in both populations underwent the simple shoulder test, an internationally validated self-administered test that highlights functional shoulder deficits, and 3 additional tests at orthopedic visits: the external rotation test, Patte test, and external rotation lag sign test. A head-and-neck cancer-specific questionnaire (University of Washington Quality of Life, version 4) was completed by the surgical patients. All statistical analyses were performed using Software IBM SPSS Statistics (IBM Corp., Armonk, NY).A total of 19 patients met the inclusion criteria: 11 males (57.8%) and 8 females (42.2%) of mean age 60.9 years (range 23-75 years). In addition, 20 age-and sex-matched volunteers with no history of shoulder pathology were evaluated in terms of shoulder functionality. The average score on the simple shoulder test was 10.55 in the healthy population versus 8.31 in the study population ( P < 0.001); in particular, shoulder strength differed between the groups. Similarly, the orthopedic examinations revealed clinically significant differences between the controls and patients on the Patte test and external rotation lag sign test (both P < 0.001), but not the external rotation test ( P > 0.001). The mean University of Washington Quality of Life was 73.39; most patients reported good quality of life (52.6%), followed by very good (15.7%).The free scapular bone tip flap is valuable for reconstruction of head-and-neck defects; the long and reliable vascularpedicle allows rapid patient mobilization. Morbidity was confined to small reductions in shoulder strength and external rotation, which do not affect quality of life.

RESUMEN

ABSTRACT: The aim of this study was to understand the impact of the COVID-19 pandemic on the epidemiology of maxillofacial trauma in a regional trauma center in L'Aquila, Abruzzo, Italy, during the first wave of the pandemic and comparted it to an equivalent period from 2015 to 2018. The authorshave retrospectively analyzed personal data, site of trauma, etiology, and mechanism of injury. Statistical analysis has been carried out utilizing IBM SPSS Statistics software (IBM Corp., Armonk, NY) and significance was accepted for P values of <0.05. From January 2015 to December 2020, a total of 296 were analyzed. In Pre-COVID era, 195 patients were evaluated, 130 males (66.6%) and 65 females (33.4%). Zygomatic-malar complex fractures were the most common site of trauma in both genders (53%), followed by mandibular fractures (23%) and orbital ones (15%). The highest incidences of injuries were recorded between 15 and 34 years (21%) with the most common etiology attributed to road accidents traumas (49%). In COVID19 era, the authors recorded 101 traumas, 58 males (57.4%), 43 females (42.6%). Zygomatic-malar complex fractures were confirmed as the most common ones in both genders (41%). The most common etiology was related to casual domestic accident and assaults (37% and 30%, respectively). There was no statistically significant difference in terms of incidence in the comparison of Pre-COVID19 and COVID19 periods (P > 0.05) as opposed to the etiology in which the road traffic accidents decreased in favor of domestic accidents and interpersonal assaults (P < 0.05). Our scientific study represents the first epidemiologic study related to the impact of COVID-19 on maxillo-facial trauma in the Province of L'Aquila, Abruzzo, Italy. A decrease in the number of Maxillofacial injuries related to road traffic accidents can be demonstrated as the benefit of lockdown, however, a significant increase in the number of physical assaults shows how isolation and restrictions have had a highly negative psychological impact on society.

RESUMEN

OBJECTIVE: First-line therapy for metastatic squamous cell carcinoma of the head and neck (R/M HNSCC) has been revolutionized by the introduction of anti-checkpoint monoclonal antibodies, which have shown a significant improvement in overall survival (OS) gaining approval in a first line setting. Efficacy and safety of first-line weekly chemotherapy, compared to 3-weeks treatment, was retrospectively evaluated in a frail patient population with R/M HNSCC with the aim to evaluate its role as part of a personalized first-line approach. METHODS: A total of 124 patients with locally incurable R/M HNSCC receiving weekly (21) or three-weekly (103) chemotherapy plus cetuximab in a first line setting from December 2010 to September 2020 were retrospectively reviewed. Treatment outcomes in terms of objective response rate (ORR), progression-free survival (PFS), overall survival (OS) and toxicities were analysed. RESULTS: Patients in the three-week subgroup were ECOG PS 0 (39) and 1 (64) while patients in weekly group (21) were all PS 2. No significant differences were reported in terms of age, sex, smoking and previous alcohol abuse considering the two distinct subgroups. Moreover, no statistically significant difference was found in PFS and OS between the two treatment subgroups. The response rate was 35% (36 patients) and 34% (7 patients) in three-week and weekly treatment group, respectively. Seventy patients (68%) in the three-week group experienced chemotherapy-related toxicities, predominantly G3. In the weekly group a predominantly low-grade toxicity was found in a lower number of patients (52%). CONCLUSION: The weekly schedule appears to be an active and safe strategy in frail patients with R/M HNSCC. Based on these data, a weekly schedule could be considered as a first line treatment in all frail patients excluded from pembrolizumab treatment and a study on the combination of weekly chemotherapy and immunotherapy should be performed.

RESUMEN

The surgical injury of the intracranial portion of the facial nerve (FN) is a severe complication of many skull base procedures, and it represents a relevant issue in terms of patients' discomfort, social interactions, risk for depression, and social costs. The aim of this study was to investigate the surgical and functional outcomes of the most common facial nerve rehabilitation techniques. The present study is a systematic review of the pertinent literature, according to the PRISMA guidelines. Two different online medical databases (PubMed, Scopus) were screened for studies reporting the functional outcome, measured by the House-Brackman (HB) scale, and complications, in FN early reanimation, following surgical injuries on its intracranial portion. Data on the VII-to-VII and XII-to-VII coaptation, the surgical technique, the use of a nerve graft, the duration of the deficit, and complications were collected and pooled. The XII-to-VII end-to-side coaptation seems to provide higher chances for functional restoration (HB 1-3) than the VII-to-VII (68.8% vs 60.6%), regardless of the duration of the palsy deficit, the use or not of a nerve graft, and the use of stitches or glues. However, its complication rate was as high as 28.6%, and a second procedure is then often needed. The XII-to-VII side-to-end coaptation is the most effective in providing a functional outcome (HB 1-3), even though it is associated to a higher complication rate. Further trials are needed to better investigate this relevant topic, in terms of health-related social costs and patients' quality of life.

RESUMEN

ABSTRACT: The epidemiology of maxillofacial fractures is variable in different geographic regions. Economic and social conditions, laws and types of behavior can be considered the most important factors influencing these differences.Mandibular fractures were first cited in 1650 BC in an Egyptian papyrus. Today, these fractures are one of the most prevalent facial skeletal injuries.A 4-year retrospective study was performed and the trauma - related data were collected from medical and radiological archives. The analysis comprised patients admitted for mandibular fracture at Sapienza University of Rome - Policlinico Umberto I between January 1, 2016 and December 31, 2019. The data include age, sex, etiology, anatomical sites of the fractures, eventual maxillofacial associated fractures and treatment.We collected 172 patients, 138 males (80.2%) and 34 females (19.8%) with 270 mandibular fractures. The average age was 35.4 years. The youngest and oldest patients were aged 6 and 90 years, respectively. The age group 20 to 29 years was the most represented with 52 patients (30.2% of the total sample). Assaults were the most common etiology (n = 53, 30.8%), followed by falls (n = 45, 26.2%). The condyle was the most involved region (n = 86, 32%), followed by parasymphysis region (n = 72, 26.6%) and angle (n = 62, 23%).154 patients (89.5%) reported only mandibular fractures. Eighteen patients (10.5%) had other associated maxillofacial fractures; the most frequently encountered maxillofacial fractures associated with mandibular fractures were the zygomatic complex fractures (n = 9, 5.2%). Open reduction and internal fixation was the most preferred surgical treatment (n = 115, 66.9%).This study showed that mandibular fractures predominate in 20 to 29 years group and in the male sex. Assaults are the most frequent cause. The prevalent fracturing site is condylar process. Orbital - maxillary - zygomatic complex fractures were the most common associated maxillofacial fractures and open reduction and internal fixation was the preferred surgical strategy.The results of this analysis agree to other studies and provide important clinical information that will help in study of these injuries.

RESUMEN

ABSTRACT: Binder Syndrome occurs in less than 1 per 10,000 live births. Mean features of the syndrome include arhinoid face, abnormal position of the nasal bones, intermaxillary hypoplasia with associated malocclusion, reduced or absent anterior nasal spine, atrophy of the nasal mucosa and absence of the frontal sinus. Treatment of these facial deformities is obviously surgical. In the present work, the authors describe, step by step, their technique in secondary rhinoplasty in a 36-years-old patient affected by Binder Syndrome. In this case, the authors used autologous cartilage graft and heterologous bone graft.Satisfying results are achieved in 12 months of follow-up: graft resorption is acceptable, position of the graft is stable, the authors have no signs of infection and the patient is satisfied with the aesthetical and functional results. The authors believe that the first option, in complex nose's reconstruction, is the use of autologous grafts but, the use of cartilage heterologous bone graft should be taken in account, in the future, as a secondary option in Binder Syndrome and in malformed patients.

RESUMEN

ABSTRACT: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has had a significant impact on people's behavior. The aim of this study has been to evaluate how the SARS-CoV-2 pandemic has impacted the incidence and the features of maxillofacial fractures presented at 6 Italian tertiary centers. Clinical records of all the patients diagnosed for facial fractures between February 23 and May 23, 2019 and 2020 were retrospectively reviewed. Any differences in patient number and characteristics and fracture etiology and site between the 2 groups were then statistically analyzed.There has been a 69.1% decrease in the number of incoming patients during the pandemic. The number of foreign patients has decreased significantly (23.3% versus 9.6%, P = 0.011) while the average age has increased (38.6 versus 45.6 years old, P = 0.01). Specific statistical significant differences for accidental falls (31.8% versus 50.1%, P = 0.005) and sports injuries (16.9% versus 1.4%, P < 0.001) were found. Concerning fracture sites, significant differences have been found in relation to nasal (22.5% versus 11.4%, P = 0.009) and frontal sinus (0.9% versus 4.4%, P = 0.037) fractures. In conclusion, SARS-CoV-2 pandemic has significantly changed the epidemiology and the etiology of facial traumas.

RESUMEN

In our study, we investigated the role of CD39 on tumor-infiltrating CD8+ T lymphocytes (CD8+ TILs) in colorectal, head and neck and pancreatic cancers. Partially confirming recent observations correlating the CD39 expression with T-cell exhaustion, we demonstrated a divergent functional activity in CD39+ CD8+ TILs. On the one hand, CD39+ CD8+ TILs (as compared to their CD39- counterparts) produced significantly lower IFN-γ and IL-2 amounts, expressed higher PD-1, and inversely correlated with perforin and granzyme B expression. On the other, they displayed a significantly higher proliferative capacity ex vivo that was inversely correlated with the PD-1 expression. Therefore, CD39+ CD8+ TILs, including those co-expressing the CD103 (a marker of T resident memory [TRM] cells), were defined as partially dysfunctional T cells that correlate with tumor patients with initial progression stages. Interestingly, our results identified for the first time a single nucleotide polymorphism (SNP rs10748643 A>G), as a genetic factor associated with CD39 expression in CD8+ TILs. Finally, we demonstrated that compounds inhibiting CD39-related ATPases improved CD39+ CD8+ T-cell effector function ex vivo, and that CD39+ CD8+ TILs displayed effective suppression function in vitro. Overall these data suggest that the SNP analysis may represent a suitable predictor of CD39+ CD8+ T-cell expression in cancer patients, and propose the modulation of CD39 as a new strategy to restore partially exhausted CD8+ TILs.

RESUMEN

The role of induction chemotherapy in the multidisciplinary treatment of locally advanced, nonlaryngeal high-risk human papilloma virus (HPV)-negative head and neck squamous cells carcinoma (HNSCC) is uncertain in terms of overall survival (OS). The primary objective of this study was to identify possible predictive factors of survival and outcome in patients with HNSCC who were treated with induction chemotherapy. Fifty-nine patients with stage IVa/b HPV-negative non-laryngeal HNSCC (mostly originating from the oral cavity) who underwent induction chemotherapy at Policlinico Umberto I were reviewed. Treatment outcomes in term of objective response rate (ORR), progression-free survival (PFS), OS and toxicities were analyzed. A significant association between nodal status, ORR, ongoing smoking use, toxicities and OS was demonstrated. ORR (obtained in 61% of patients) was associated with a reduction in mortality of 80% (P< 0.0001). Early discontinuation after just one cycle of induction chemotherapy was associated to a significantly shorter OS. In oral cavity radical surgery with negative margins was obtained in 15/16 patients. In 42% of patients G3-G4 toxicity occurred. Toxicity requiring hospitalization occurred in 42% and 21% of patients with oropharyngeal and oral cavity carcinoma, respectively. Five patients died of treatment-related causes. No treatment-related mortality occurred in oral cavity patients. G5 toxicities were different according to the sub-sites of disease (P = 0.05). Induction chemotherapy in non-laryngeal high-risk HNSCC is an active strategy, most importantly in oral cavity cancer, even though burdened with a high (G ≥ 3) toxicity and early discontinuation rate. These data will however need to be confirmed in further and larger studies.

RESUMEN

Benign osseous tumors of the frontal bone can be treated with endoscopic surgery, minimizing postoperative complications associated with the coronal approach and guaranteeing more functional and aesthetic results. The authors describe a case of a patient who had endoscopic removal of osteoma of the forehead using two 1 cm incisions behind the hairline. No complications such as hematoma and edema were detected. Endoscopic technique offered both good illumination and excellent magnification; it permitted safe anatomic dissection, minimum bleeding, avoiding visible scars. The outcome achieved with endoscopic technique could be the first-line surgical treatment of benign bone tumors of the frontal area, offering more advantages and better results than the conventional surgical approaches.

RESUMEN

The aim of this work is to illustrate a transoral mini-invasive approach to safely remove elongated styloid process in Eagle syndrome. A 34-year-old Asian male came to our center referring pharyngeal and cervical pain on the right side on swallowing and opening the mouth. Computed tomography showed elongation of the right styloid process. Surgical removal was performed through endoscopy-assisted intraoral approach using a pituitary curette to perform dissection and piezosurgery for the osteotomy. Surgical intervention was completed in 25 minutes. Postoperative period was uneventful except for transient (12 hours) right facial palsy that resolved spontaneously. Two months after surgery, patient referred resolution of symptoms. This technique is easy to perform and permits to obtain good result with reduction of surgical time and with low risk of complication.

RESUMEN

OBJECTIVE: Fascia lata (FL) is a worldwide adopted source of autologous grafts. In our Department, the endoscopic endonasal transphenoidal surgery (EETS) has been performed regularly for anterior and middle cranial fossa lesions, and FL graft has commonly been a practical resource in repairing tissue defects after EETS.Enough, we used routinely harvesting FL to restore symmetry in facial palsy. To our known, this is the biggest case series about FL harvesting to repare tissue defects after EET. The purpose of our study was to evaluate our experience with the harvesting of FL, in particularly the donor site morbidity. STUDY DESIGN: This is a prospective study case series, which evaluated by questionnaire the morbidity of FL donr site. METHODS: The details of 44 patients were analyzed from 2011 to 2016. Thirty-eight patients needed cranial base reconstruction and 6 patients needed facial reanimation. RESULTS: Adequate length of FL was harvested in all our patients. There were no intraoperative complications. We did not use drain in any case. We analyzed 18 women (40%) and 26 men (59.9%). The estimated median age at presentation was 51.53. CONCLUSION: For little FL's gap, diameter until 3 × 6 cm, it's possible to suture FL's margin with Nylon, but for bigger gap it's necessary to reconstruct with allograft to avoid muscle bulge or compartmental syndrome.
