Bone reconstruction using CAD/CAM technology in head and neck surgical oncology. A narrative review of state of the art and aesthetic-functional outcomes.

Bone defects following resections for head and neck tumours can cause significant functional and aesthetic defects. The choice of the optimal reconstructive method depends on several factors such as the size of the defect, location of the tumour, patient's health and surgeon's experience. The reconstructive gold standard is today represented by revascularised osteo-myocutaneous or osteomuscular flaps with osteosynthesis using titanium plates. Commonly used donor sites are the fibula, iliac crest, and lateral scapula/scapular angle. In recent years, computer-aided design (CAD)/computer assisted manufacturing (CAM) systems have revolutionised the reconstructive field, with the introduction of stereolithographic models, followed by virtual planning software and 3D printing of plates and prostheses. This technology has demonstrated excellent reliability in terms of accuracy, precision and predictability, leading to better operative outcomes, reduced surgical times and decreased complication rates. Among the disadvantages are high costs, implementation times and poor planning adaptability. These problems are finding a partial solution in the development of "in house" laboratories for planning and 3D printing. Strong indications for the use of CAD/CAM technologies today are the reconstruction of total or subtotal mandibular or maxillary defects and secondary bone reconstructions.

Changes in hospital admissions for facial fractures during and after COVID 19 pandemic: national multicentric epidemiological analysis on 2938 patients.

PURPOSE: The objective of this multicenter study was to examine the differences in maxillo-facial fractures epidemiology across the various phases of the SARS-CoV-2 pandemic. METHODS: This is a retrospective study on patients who underwent surgery for facial bone fractures in 18 maxillo-facial surgery departments in Italy, spanning from June 23, 2019, to February 23, 2022. Based on the admission date, the data were classified into four chronological periods reflecting distinct periods of restrictions in Italy: pre-pandemic, first wave, partial restrictions, and post-pandemic. Epidemiological differences across the groups were analysed. RESULTS: The study included 2938 patients. A statistically significant difference in hospitalization causes was detected between the pre-pandemic and first wave groups (p = 0.005) and between the pre-pandemic and partial restriction groups (p = 0.002). The differences between the pre- and post-pandemic groups were instead not significant (p = 0.106). Compared to the pre-pandemic period, the number of patients of African origin was significantly higher during the first wave and the post-pandemic period. No statistically significant differences were found across the periods concerning gender, age, fracture type, treatment approach, and hospital stay duration CONCLUSIONS: The COVID-19 pandemic brought about significant changes in fracture epidemiology, influenced by the restrictive measures enforced by the government in Italy. Upon the pandemic's conclusion, the fracture epidemiology returned to the patterns observed in the pre-pandemic period.

Locoregional Flaps for the Reconstruction of Midface Skin Defects: A Collection of Key Surgical Techniques.

BACKGROUND: The reconstruction of midface skin defects represents a challenge for the head and neck surgeon due to the midface's significant role in defining important facial traits. Due to the high complexity of the midface region, there is no possibility to use one definitive flap for all purposes. For moderate defects, the most common reconstructive techniques are represented by regional flaps. These flaps can be defined as donor tissue with a pedunculated axial blood supply not necessarily adjacent to the defect. The aim of this study is to highlight the more common surgical techniques adopted for midface reconstruction, providing a focus on each technique with its description and indications. METHODS: A literature review was conducted using PubMed, an international database. The target of the research was to collect at least 10 different surgical techniques. RESULTS: Twelve different techniques were selected and cataloged. The flaps included were the bilobed flap, rhomboid flap, facial-artery-based flaps (nasolabial flap, island composite nasal flap, retroangular flap), cervicofacial flap, paramedian forehead flap, frontal hairline island flap, keystone flap, Karapandzic flap, Abbè flap, and Mustardè flap. CONCLUSIONS: The study of the facial subunits, the location and size of the defect, the choice of the appropriate flap, and respect for the vascular pedicles are the key elements for optimal outcomes.

Submandibular gland involvement in oral cavity squamous cell carcinoma: a retrospective multicenter study.

BACKGROUND: The submandibular gland (SMG) is routinely excised during neck dissection. Given the importance of the SMG in saliva production, it is important to understand its involvement rate by cancer tissue and the feasibility of its preservation. METHODS: Retrospective data were collected from five academic centers in Europe. The study involved adult patients affected by primary oral cavity carcinoma (OCC) undergoing tumor excision and neck dissection. The main outcome analyzed was the SMG involvement rate. A systematic review and a meta-analysis were also conducted to provide an updated synthesis of the topic. RESULTS: A total of 642 patients were enrolled. The SMG involvement rate was 12/642 (1.9%; 95% CI 1.0-3.2) when considered per patient, and 12/852 (1.4%; 95% CI 0.6-2.1) when considered per gland. All the glands involved were ipsilateral to the tumor. Statistical analysis showed that predictive factors for gland invasion were: advanced pT status, advanced nodal involvement, presence of extracapsular spread and perivascular invasion. The involvement of level I lymph nodes was associated with gland invasion in 9 out of 12 cases. pN0 cases were correlated with a reduced risk of SMG involvement. The review of the literature and the meta-analysis confirmed the rare involvement of the SMG: on the 4458 patients and 5037 glands analyzed, the involvement rate was 1.8% (99% CI 1.1-2.7) and 1.6% (99% CI 1.0-2.4), respectively. CONCLUSIONS: The incidence of SMG involvement in primary OCC is rare. Therefore, exploring gland preservation as an option in selected cases would be reasonable. Future prospective studies are needed to investigate the oncological safety and the real impact on quality of life of SMG preservation.

Oral cavity carcinoma in patients with and without a history of lichen planus: A comparative analysis.

BACKGROUND: Oral potentially malignant disorders (OPMD) are associated with the risk of malignant transformation (MT) into oral cavity carcinoma (OCC). Oral lichen planus (OLP) is one of the most common OPMDs in western countries. Although there is a substantial amount of research on progression to cancer, a specific analysis of the clinical characteristics and prognosis of cancer developed in patients with a history of OLP versus patients without a history of OLP has not been investigated so far. METHODS: Retrospective evaluation of 82 patients treated for OCC with a known history of OLP compared to a representative sample of 82 patients treated for OCC without a known history of LP. Comparative analyses were performed on age at presentation, sex, TNM staging, clinical characteristics, pathology characteristics, 2- and 5-year overall survival (OS), and disease-free survival (DFS). RESULTS: It was shown that patients with a history of LP were significantly younger at first presentation than patients without a history of LP (mean age difference 6.7 years, 95% CI 3.1-10.3, p < 0.05). Also, patients with a history of OLP were in higher proportion females. The main pathological stage at presentation was significantly lower in the OLP group (p < 0.05). The 2-year survival analysis showed that DFS and OS were significantly lower in patients without a known history of OLP, with a hazard ratio (HR) of 3.1 (95% CI 1.4-6.8) and HR of 2.6 (95% CI 1.3-5.3), respectively. The 5-year survival analysis showed that DFS and OS were significantly lower in patients without a known history of OLP, with a hazard ratio of 3.1 (95% CI 1.6-6.2) and of 2.9 (95% CI 1.5-5.6), respectively. CONCLUSIONS: Cancer arising from OLP has peculiar characteristics compared to cancer in naïve patients. It most commonly affects younger patients, women, and nonsmokers. It is usually diagnosed at earlier stages and appears to have less aggressive behavior at presentation. Moreover, when 2- and 5-year survival is analyzed, it appears that patients in OLP group have an overall and a disease-free survival advantage. These results suggest that cancer from OLP is less aggressive and thus has a potential biological difference with cancer arising in non-OLP patients. Further clinical and basic investigations are needed to confirm the results of this study.

A multicenter randomized trial for quality of life evaluation by non-invasive intelligent tools during post-curative treatment follow-up for head and neck cancer: Clinical study protocol.

Patients surviving head and neck cancer (HNC) suffer from high physical, psychological, and socioeconomic burdens. Achieving cancer-free survival with an optimal quality of life (QoL) is the primary goal for HNC patient management. So, maintaining lifelong surveillance is critical. An ambitious goal would be to carry this out through the advanced analysis of environmental, emotional, and behavioral data unobtrusively collected from mobile devices. The aim of this clinical trial is to reduce, with non-invasive tools (i.e., patients' mobile devices), the proportion of HNC survivors (i.e., having completed their curative treatment from 3 months to 10 years) experiencing a clinically relevant reduction in QoL during follow-up. The Big Data for Quality of Life (BD4QoL) study is an international, multicenter, randomized (2:1), open-label trial. The primary endpoint is a clinically relevant global health-related EORTC QLQ-C30 QoL deterioration (decrease ≥10 points) at any point during 24 months post-treatment follow-up. The target sample size is 420 patients. Patients will be randomized to be followed up using the BD4QoL platform or per standard clinical practice. The BD4QoL platform includes a set of services to allow patients monitoring and empowerment through two main tools: a mobile application installed on participants' smartphones, that includes a chatbot for e-coaching, and the Point of Care dashboard, to let the investigators manage patients data. In both arms, participants will be asked to complete QoL questionnaires at study entry and once every 6 months, and will undergo post-treatment follow up as per clinical practice. Patients randomized to the intervention arm (n=280) will receive access to the BD4QoL platform, those in the control arm (n=140) will not. Eligibility criteria include completing curative treatments for non-metastatic HNC and the use of an Android-based smartphone. Patients undergoing active treatments or with synchronous cancers are excluded. Clinical Trial Registration: ClinicalTrials.gov, identifier (NCT05315570).

Metastatic Lung Cancer to the Head and Neck: A Clinico-Pathological Study on 21 Cases with Narrative Review of the Literature.

Metastases from lung cancer to the oral cavity and to the head and neck generally are very infrequent and usually manifest in advanced stages of the disease. Even more rarely, they are the first sign of an unknown metastatic disease. Nevertheless, their occurrence always represents a challenging situation both for clinicians, in the management of very unusual lesions, and for pathologists, in the recognition of the primary site. We retrospectively studied 21 cases of metastases to the head and neck from lung cancer (sixteen males and five females, age range 43-80 years; eight cases localized to the gingiva [two of these to the peri-implant gingiva], seven to the sub-mandibular lymph nodes, two to the mandible, three to the tongue, one case to the parotid gland; in eight patients, metastasis was the first clinical manifestation of an occult lung cancer) and proposed a wide immunohistochemical panel for a proper identification of the primary tumor histotype, including CK5/6, CK8/18, CK7, CK20, p40, p63, TTF-1, CDX2, Chromogranin A, Synaptophysin, GATA-3, Estrogen Receptors, PAX8, PSA. Furthermore, we collected data from previously published studies and narratively reviewed the relevant literature.

Relationship between oral lesions and severe SARS-CoV-2 infection in intensive care unit patients.

OBJECTIVE: Oral lesions received increased attention as likely new signs or secondary manifestations of COVID-19. Therefore, we clinically examined oral cavity of patients with COVID-19 and investigated oral lesions and patient comorbidities as possible risk factors of COVID-19 disease outcome. METHODS: From January to March 2022, a prospective study was conducted by recruiting all COVID-19 patients admitted to the Intensive Care Unit and Respiratory Intensive Care Unit of Maxi-Emergencies Hospital in Bari, Italy. RESULTS: From the enrolled 103 COVID-19 patients, 46.6% were females and 53.4% were males. Findings show that risk of presenting with severe COVID-19 disease was higher in patients who developed oral lesions related to COVID-19 than those with no oral lesions (RR = 7.998, p = .002). Next, patients with concomitant autoimmune diseases were at higher risk of a negative COVID-19 disease outcome than those without comorbidities (OR = 8.838, p = .026). CONCLUSIONS: COVID-19-related lesions of oral mucosa should not be ignored as they can be early and easily detectable signs of severe COVID-19 disease condition, thus, serving as a prevention measure for any potential unfortunate event. Findings of this study, without implying causation, offer a direction for future investigations that aim to confirm the presence of specific oral lesions in COVID-19 patients as signs of severe disease progression.

Myomucosal island flap in the reconstruction of oral cavity defects: Description of the surgical technique.

Multiple options are available for the reconstruction of the defects of the oral cavity. Among these, the facial artery myomucosal island flap (FAMMIF) is a pedicled flap composed by cheek mucosa, submucosa, and part of the buccinator muscle. The FAMMIF is ideal for the reconstruction of small-to-moderate defects of the oral cavity and the oropharynx. This is due to low operating time, low morbidity, and good functional and aesthetic results. A step-by-step description of the flap harvesting is presented, with particular attention to flap design, identification of the vessels, harvesting of the myomucosal island, tunnel preparation for its passage in the neck and back to the oral cavity, and closure of the cheek donor site with the buccal fat pad.

Characteristics and age-related injury patterns of maxillofacial fractures in children and adolescents: A multicentric and prospective study.

BACKGROUND/AIMS: Paediatric maxillofacial trauma accounts for 15% of all maxillofacial trauma but remains a leading cause of mortality. The aim of this prospective, multicentric epidemiological study was to analyse the characteristics of maxillofacial fractures in paediatric patients managed in 14 maxillofacial surgery departments on five continents over a 1-year period. METHODS: The following data were collected: age (preschool [0-6 years], school age [7-12 years], and adolescent [13-18 years]), cause and mechanism of the maxillofacial fracture, alcohol and/or drug abuse at the time of trauma, fracture site, Facial Injury Severity Scale score, associated injuries, day of the maxillofacial trauma, timing and type of treatment, and length of hospitalization. Statistical analyses were performed using SPSS software. RESULTS: Between 30 September 2019 and 4 October 2020, 322 patients (male:female ratio, 2.3:1) aged 0-18 years (median age, 15 years) were hospitalized with maxillofacial trauma. The most frequent causes of the trauma were road traffic accidents (36%; median age, 15 years), followed by falls (24%; median age, 8 years) and sports (21%; median age, 14 years). Alcohol and/or drug abuse was significantly associated with males (p < .001) and older age (p < .001). Overall, 474 fractures were observed (1.47 per capita). The most affected site was the mandibular condyle in children <13 years old and the nose in adolescents. The proportion of patients who underwent open reduction and internal fixation increased with age (p < .001). CONCLUSION: The main cause of paediatric maxillofacial fractures was road traffic accidents, with the highest rates seen in African and Asian centres, and the frequency of such fractures increased with age. Falls showed an inverse association with age and were the leading cause of trauma in children 0-6 years of age. The choice of treatment varies with age, reflecting anatomical and etiological changes towards patterns more similar to those seen in adulthood.

A multicentric prospective analysis of maxillofacial trauma in the elderly population.

BACKGROUND/AIMS: The growth of the global elderly population will lead to an increase in traumatic injuries in this group, including those affecting the maxillofacial area, with a heavier load on health systems. The aim of this multicentric prospective study was to understand and evaluate the incidences, causes and patterns of oral and maxillofacial injuries in patients aged over 60 years admitted to 14 maxillofacial surgical departments around the world. METHODS: The following data were collected: gender, cause and mechanism of maxillofacial fracture, alcohol and drug abuse at the time of trauma, fracture site, Facial Injury Severity Scale score, associated injury, day of trauma, timing and type of treatment and length of hospitalization. Statistical analyses were performed using non-parametric and association tests, as well as linear regression. RESULTS: Between 30 September 2019 and 4 October 2020, 348 out of 2387 patients (14.6%), 197 men and 151 women (ratio 1.3:1; mean age 72.7 years), were hospitalized. The main causes of the maxillofacial fractures were falls (66.4%), followed by road traffic accidents (21.5%) and assaults (5.2%). Of the 472 maxillofacial fractures, 69.7% were in the middle third of the face, 28% in the lower third and 2.3% in the upper third. Patients with middle third fractures were on average 4.2 years older than patients with lower third fractures (95% CI 1.2-7.2). Statistical analysis showed that women were more involved in fall-related trauma compared with males (p < .001). It was also shown that road traffic accidents cause more fractures in the lower third (p < .001) and in the middle third-lower third complex compared with upper third (p < .001). CONCLUSIONS: Maxillofacial fractures in the elderly were more frequent in European and Australian centres and affected men slightly more than women. Falls were the leading cause of fractures, especially among women. The middle third of the face was most often affected, and conservative treatment was the most common choice for the management of such patients.

Antibiotic prophylaxis in head and neck cancer surgery: Systematic review and Bayesian network meta-analysis.

Postoperative surgical site infections (SSI) are worrisome complications after head and neck cancer surgery. Due to the lack of direct comparisons, it is difficult to indicate the best antibiotic in the setting of SSI prophylaxis for patients with head and neck cancer. For this reason, we decided to conduct a Bayesian network meta-analysis of clinical studies evaluating various antibiotic classes for SSI prophylaxis; thus, we directly and indirectly compared all the available antibiotics in the setting of head and neck oncological surgery. We performed a systematic review and a network meta-analysis according to the PRISMA-NMA checklist. Regarding inclusion criteria, we included articles with retrospective or prospective design recruiting adult participants with head and neck neoplasm of any subsite that compared different antibiotics or that compared different antibiotic treatment duration with sample sizes of more than 10 patients. Overall, 310 citations were identified by the search on all databases. Of these, 250 were excluded based on title and abstract, leaving 60 publications for full text examination. Finally, 20 papers were included for data extraction and analysis. In total, 8627 patients were evaluated across the included studies. Results of the Bayesian network meta-analysis showed that when compared to clindamycin short course, the antibiotics effective in preventing SSI were ampicillin/sulbactam or other penicillin short course (OR: 0.37, 95%CrI: 0.19-0.72), cefazolin/metronidazole short course (OR: 0.26, 95%CrI: 0.06-0.93), cefazolin (OR: 0.36, 95%CrI: 0.17-0.79), ampicillin/sulbactam long course (OR: 0.20, 95%CrI: 0.04-0.91), cefazolin/metronidazole long course (OR: 0.27, 95%CrI: 0.09-0.64), cefoperazone (OR: 0.05, 95%CrI: 0.002-0.89), cefotaxime (OR: 0.04, 95%CrI: 0.002-0.85). There was no significant difference between clindamycin and no antibiotic (OR: 2.3, 95%CrI: 0.59-9.9). Clindamycin plus aminoglycoside seemed to give a slight protection from SSI compared to clindamycin alone (OR: 0.30, 95%CrI: 0.09-0.99) or no antibiotic (OR: 0.13, 95%CrI: 0.02-067). Antibiotic prophylaxis is important in preventing SSI in head and neck cancer setting. Current evidence suggests that penicillins and cephalosporins are the best choice. Moreover, long duration course does not give any advantage compared to short course prophylaxis. Finally, it is important to implement appropriate antibiotic prophylaxis in patients that are labeled as penicillin allergic, in this regard clindamycin seems to be ineffective and, for this reason, further research is needed to provide a better care for this subset of patients.

Trismus and TMJ disorders as first clinical manifestations in an intracranial acquired cholesteatoma.

Intracranial extension of acquired cholesteatoma is a rare occurrence that can develop secondary to trauma, chronic otitis media or acquired aural cholesteatoma. The most commonly observed symptoms are headache and hearing loss. The authors report on a rare case of intracranial cholesteatoma presenting with atypic symptoms: swelling and temporomandibular joint disorders.

Dyskeratosis congenita and squamous cell carcinoma of the mandibular alveolar ridge.

Dyskeratosis congenita is a rare disease caused by telomerase dysfunction classically characterised by the triad: skin pigmentation, nail dystrophy and mucosal leukoplakia. Few cases are described in literature regarding patients with head and neck squamous cell carcinoma affected by dyskeratosis congenita, and the therapeutic decisions are not yet well defined. A review of the literature of the last 20 years (2001-2021) was performed, and it was analysed the case of a 38-year-old male patient affected by dyskeratosis congenita diagnosed with a squamous cell carcinoma of the inferior alveolar ridge, treated with surgery. The absence of complications and the good postoperative recovery of the patient comfort in saying that resection and reconstructive surgery can be safely performed. The occurrence of disseminated disease 6 months after the treatment warns about the extreme aggressiveness of the pathology, its often systemic nature and the necessity of a multidisciplinary approach as well as further studies.

Managing head and neck cancer patients during the COVID-19 pandemic: the experience of a tertiary referral center in southern Italy.

BACKGROUND: The medical community has been deeply involved in fighting the Coronavirus disease 2019 (COVID-19) pandemic and, as a consequence, the care of non-COVID-19 patients has been impacted. However, the treatment of head and neck cancer patients is not deferrable, and an integrated strategy is required. The aim of the current article is to present the experience in the management of head and neck patients during the COVID-19 pandemic at the research hospital "Casa Sollievo della Sofferenza". This review contains replicable and widely usable instructions on how to avoid delays in the diagnosis and treatment of head and neck tumors and to ensure a gradual return to elective procedures. MAIN TEXT: The Head and Neck Department of the research hospital "Casa Sollievo della Sofferenza" includes an Otolaryngology and a Maxillofacial Surgery Unit, both of which deal with the diagnosis and treatment of benign and malignant pathologies of the head and neck, as well as urgent/emergent consultations and surgical procedures that necessitate time sensitive operative management, such as cochlear implantation (CI). Given these premises and the complexity of the Department, the "COVID-19 organizing protocol" of the research hospital "Casa Sollievo della Sofferenza" was divided into two phases in accordance with the different stages of the pandemic and the priority of treatment. Special attention was given to the medical surveillance of health care workers and hospitalized patients, to the organization of the outpatient clinic and the operating setting as well as to the implementation of telehealth systems. CONCLUSIONS: The COVID-19 pandemic is going to be a long-term situation with lasting effects on the public health and the entire society. Therefore, an efficient health care system has to adopt a double strategy: always being ready for a "new wave" of the pandemic and not forgetting non-COVID-19 patients, among whom head and neck cancer patients represent a priority. More than 1 year since the first outbreak in Wuhan, this review offers a unique and helpful perspective that incorporates awareness of the disease.

Accuracy of Fibula Reconstruction Using Patient-Specific Cad/Cam Plates: A Multicenter Study on 47 Patients.

OBJECTIVES: This prospective study evaluated the accuracy of mandibular reconstruction using free fibular flaps (by comparing virtual plans to the three-dimensional postoperative results), and the extent of bone-to-bone contact after computer-assisted surgery. METHODS: We included 65 patients who underwent partial-continuity mandibular resections from February 2013 to January 2017, and evaluated virtual planning, surgical techniques, and accuracy. RESULTS: Forty-seven patients were analysed. A total of 112 fibular segments received 54 implants. We measured 227 distances between landmarks to assess the accuracy of reconstruction. Postoperative reconstruction accuracy ranged from 0.5 to 3 mm. CONCLUSION: Virtual surgical planning very accurately translated simulation into reality, particularly in patients requiring large, complex mandibular reconstructions using multiple fibular segments. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:E2169-E2175, 2021.

Adequacy of the Italian National Tariff for Orthognathic Surgery: A Cost Analysis Using the Activity Based Costing (ABC) Method.

ABSTRACT: The reduced economic resources in health care and the consequent spending review have brought great interest in surgical costs. The aim of the study is to determine direct hospital costs for Orthognathic procedures using the Activity based costing method and evaluate the adequacy of the refund provided by the Italian National Health Service. From January 2017 to December 2017 9 consecutive patients underwent the following Orthognathic procedures at IRCCS Casa Sollievo della Sofferenza (San Giovanni Rotondo, Italy): bimaxillary osteotomy (n = 7), Le Fort I osteotomy (n = 1) and Bilateral Sagittal Split Osteotomy (BSSO) (n = 1). Activity based costing was used to obtain costs of each single hospitalization split into surgery, instay, and services. The mean total cost for a bimaxillary osteotomy was 7596.40€. We observed a total cost of 3925.00€ for Le Fort I osteotomy and of 4334.50€ for BSSO. The refund of 4378.00€ provided by the Italian National Health Service system for Orthognathic surgery seems insufficient to cover costs of bimaxillary osteotomy but consistent for single osteotomy (Le Fort I or BSSO).

Anatomic landmarks for masseteric nerve identification: Anatomic study for a new reference point.

The masseteric nerve is often used as a donor nerve in the treatment of facial paralysis. Even if several anatomical studies described landmarks for its identification, their main disadvantages are the anatomical variability and the changes due to surgery. Sixteen dissections were performed on cadaveric specimens. The masseteric muscle (MM), the zygomatic arch (ZA), the masseteric nerve (MN) and the zygomatic branch of the facial nerve (ZB) were identified and their relationships were measured. The relationships between MN and ZB resulted to be constant, with MN intersecting ZB at a depth of 0,78 cm in the muscle, 1,6 cm below ZA and 0,8 cm from the posterior border of MM. The measures obtained demonstrated as the main zygomatic branch of the facial nerve can be a suitable landmark for the identification of the masseteric nerve, with no variations due to the surgical procedure or patient characteristics.

Italian cost analysis of free flap surgery in head and neck reconstruction using the activity-based costing (ABC).

The aim of the study is to evaluate costs of free flap surgery for head and neck (H & N) reconstructions using the time-driven activity-based costing (ABC) method and to compare them with the refund provided by the Italian National Health System (NHS) amounting to 11,891€. We retrospectively selected 29 consecutive patients underwent free flap reconstruction in 2013 at IRCCS Casa Sollievo della Sofferenza. Patients were divided into three groups: Group 1 (n = 10) included patients receiving radial forearm free flap (RFFF), Group 2 (n = 10) receiving anterolateral thigh (ALT) free flap, and Group 3 (n = 9) composed of patients having fibular free flap. For each patient, costs were calculated using the ABC and divided into instay, surgical, and services costs. We observed an overall mean total cost of 27,802.40€. The mean costs related to hospital stay were 9,800.70€. The mean costs for surgery were 13,097.60€ and amounted to 4,904.10€ for services. RFFF appears to be less costing (25,175.40€) compared with ALT (29,191.60€) and fibula free flap (29,040.20€). ABC is an appropriate method to determine actual costs of free flap surgery by correctly allocating the resources used. The Italian NHS tariff seems to be inadequate to cover the real cost of this type of surgery.
