Masseteric cooptation and crossfacial nerve grafting: Is it still applicable 22 months after the onset of facial palsy?

BACKGROUND: Eighteen months is usually considered the cutoff time within which recovery of the mimic muscle remains possible using facial nerve cooptation. Few reports on the use of cooptation after this interval have appeared. Purpose of this study is to investigate the feasibility of this procedure also after 22 months. METHODS: Six patients treated via crossfacial nerve grafting between healthy and paralyzed middle and middle-upper facial nerve branches and masseteric cooptation of the main trunk of the paralyzed facial nerve between 20 and 24 months after the onset of palsy were analyzed. Population consisted of two males and four females ages 8-42 years (mean 24 years). Facial palsy developed after acoustic neuroma resection in three patients, after the removal of a cerebellopontine angle astrocytoma in one, and as a consequence of Bell's palsy or cerebral hemorrhage in the other two (one each). House-Brackman and Sunnybrook clinical evaluation systems and FDI questionnaire were used to assess results. RESULTS: House-Brackman scores changed from VI before the operation for all patients to II for two patients and III for four patients. Sunnybrook scores were 0-10 before the operation, but 62-84 at the last visit. Mean FDI scores moved from 24 to 38.5 meaning a statistical high significant improvement (P < .01). CONCLUSIONS: Masseteric/crossfacial nerve grafting is feasible for patients with palsies 20-24 months in duration, affording satisfactory functional and esthetic results and a dramatic improvement in quality of life.

T helper type 1-related molecules as well as interleukin-15 are hyperexpressed in the skin lesions of patients with pyoderma gangrenosum.

Pyoderma gangrenosum (PG) is a rare, immune-mediated skin disease classified into the group of neutrophilic dermatoses. Although a number of studies confirmed the central role of innate immunity, only few studies have investigated the possible contributing role of acquired immunity. In particular, no reports concerning T helper type 1 (Th1) and Th2 cells are available as yet. Therefore, 15 patients with PG, five with Sweet's syndrome (SS) and nine skin specimens from healthy controls (HC) were investigated, evaluating the expression of Th1-related markers interleukin (IL)-12, interferon (IFN)-γ, C-X-C motif chemokine receptor 3 (CXCR3) and C-C motif chemokine receptor 5 (CCR5), of the Th2-related molecules IL-4, IL-5, IL-13 and CCR3, of the co-stimulatory axis CD40/CD40 ligand, of IL-15 and the natural killer (NK) cell marker CD56 in skin lesions by immunohistochemistry. Patients with PG and SS showed a higher expression of Th1 markers than HC. Conversely, IL-5- and CCR3-expressing cells were less numerous in PG skin lesions compared to SS (P = 0·0157 and < 0·0001, respectively). Both CD40 and CD40L were expressed more in PG than in SS and HC (P < 0·0001 for both). Finally, the number of IL-15+ and CD56+ cells was higher in the skin of patients with PG than in those of SS and HC (P < 0·0001 for both). Our results suggest that Th2 cells are down-regulated in PG. At the same time, over-expression of the co-stimulatory axis CD40/CD40L amplifies the impairment of the Th1/Th2 balance. Both these findings might explain the most aggressive behaviour of PG in comparison to SS. Moreover, over-expression of IL-15+ and CD56+ cells may suggest a possible role of NK cells in the pathogenesis of the disease.

Cutaneous vasculitidis: histology and immunofluorescence.

Cutaneous vasculitis comprises a wide spectrum of diseases that involve predominantly the blood vessels and surrounding tissues of the skin. Few vasculitic syndromes have pathognomonic clinical, radiographic and/or laboratory findings; thus, confident and accurate diagnosis of vasculitis requires histological confirmation. Skin biopsy should be done, optimally within 24 to 48 hours after vasculitic lesions appear. Deep excision biopsy must be preferred. Direct immunofluorescence of lesional skin is helpful in the diagnosis of vasculitides in the light of a proper clinico-pathological setting and diagnostic in some peculiarly forms. Cutaneous histological patterns can be used to generate relevant clinical differential diagnoses, and, when coupled with patient's history, clinical and laboratory data, allow more precise and accurate diagnosis of vasculitic syndromes. This review will focus on histopathological and immunologic pattern of the more common cutaneous vasculitis syndromes, based on the 2012 Revised International CHCC.

Regulatory T cells in skin lesions and blood of patients with bullous pemphigoid.

BACKGROUND: Although regulatory T cells (Tregs) are affected in several autoimmune skin diseases, only two studies have been performed in patients with bullous pemphigoid (BP) with contrasting results. OBJECTIVE: To characterize Tregs and to determine the serum levels of regulatory cytokines in patients with BP. METHODS: In BP lesional skin, immunohistochemistry and confocal microscopy were performed for CD4(+) , CD25(+) , forkhead/winged helix transcription factor (FOXP3)(+) , transforming growth factor (TGF)-ß(+) and interleukin (IL)-10(+) cells. In addition, the number of CD4(+) CD25(++) FOXP3(+) Tregs in peripheral blood was assessed by flow cytometry, and the levels of TGF-ß and IL-10 were determined in serum samples by enzyme-linked immunosorbent assay before and after steroid therapy. Controls included patients with psoriasis, atopic dermatitis (AD) and healthy donors. RESULTS: The frequency of FOXP3(+) cells was significantly reduced in skin lesions from patients with BP (P < 0.001) compared with psoriasis and AD. Moreover, the number of IL-10(+) cells was lower in BP than in psoriasis (P < 0.001) and AD (P = 0.002), while no differences were observed in the number of TGF-ß(+) cells. CD4(+) CD25(++) FOXP3(+) Treg in the peripheral blood of patients with BP was significantly reduced compared with healthy controls (P < 0.001), and augmented significantly after steroid therapy (P = 0.001). Finally, TGF-ß and IL-10 serum levels were similar in patients with BP compared with healthy controls. However, after therapy, BP patients showed significantly higher IL-10 serum levels than before therapy (P = 0.01). CONCLUSIONS: These data suggest that the depletion of Tregs and of IL-10 in patients with BP may be an important factor in the pathogenesis of the disease.

Perioperative pain management after scapular tip free flap harvesting for head and neck reconstruction using mini-catheters to inject the local anesthetic.

PURPOSE: Although functional and esthetic results after the use of a scapular tip free flap (STFF) in head and neck reconstruction, and the related donor-site morbidity, have been extensively described, data regarding acute postoperative donor-site pain management are lacking. Purpose of this study is to explore the use of mini-catheters to administer local anesthetics for donor-site pain management after reconstruction using STFF. METHODS: Patients who underwent head and neck reconstruction using a STFF were prospectively enrolled and, through a perineural catheter placed in the donor site during the surgical procedure, a bolus of chirochaine was injected before the patient regained consciousness and at 8, 16, and 24 h postoperatively. Before and 40 min after each dose administration, donor-site pain on a numerical rating scale (NRS; 0-10) was evaluated. RESULTS: Study population consisted of 20 patients (40-88 years). At 8 h, the pain scores before and after the injection were 0-10 (mean 3.35) and 0-5 (mean 1.25), respectively. At 16 h, the pain scores before and after the injection were 0-8 (mean 2.55) and 0-4 (mean 0.55), respectively. At 24 h, the pain scores before and after the injection were 0-8 (mean 1.30) and 0-4 (mean 0.30), respectively. CONCLUSION: Statistical analysis confirmed a significant difference between the pain scores before and after administration at 8, 16, and 24 h (p < 0.001, p < 0.001, and p = 0.003, respectively). Mini-catheters for local anesthetic administration represent an effective strategy for pain control after STFF harvesting for head and neck reconstruction.

What kind of surgery for cervical carcinoma?

The incidence and mortality of cervical cancer have changed over the past 50 years in developed countries, but this kind of tumor still remains a significant clinical problem because it is the second most common cause of morbidity and mortality from cancer among women. After histological confirmation of invasive cervical cancer, the extent of disease was determined using clinical criteria to assign a stage. This assessment is important because, while for the other gynecologic cancers clinical information obtained by surgery and histopathological examination is implemented and concurs to define the staging of the disease, the cervical cancer tumor stage is given after the primary diagnosis. In this review we discuss how the surgical approach to cervical cancer has been evolved, in order to modulate the radicality of the intervention itself and thus to preserve the pelvic innervation. This step has been achieved by deepening knowledge of functional pelvic anatomy and modulating the radicality of hysterectomy according to well defined surgical landmarks.

Immunological activity of photodynamic therapy for genital warts.

BACKGROUND: An increasing body of evidence supports the usefulness of photodynamic therapy (PDT) in the treatment of non-neoplastic pathological conditions, including genital warts. In particular, PDT has demonstrated good clinical cure rates and low recurrence, and is now suggested as a safe alternative means of treating condylomata. OBJECTIVE: To confirm the suitability of aminolaevulinic acid (ALA)-PDT for the treatment of this condition and to investigate the recruitment and significance of immune cells in lesional areas by immunohistochemical analysis at different time intervals after treatment. METHODS: Fifteen subjects with histologically proven, recalcitrant condylomata acuminata of the penis, urethra, vulva or perianal area underwent several cycles of PDT following ALA application. Biopsies were taken at baseline and at different intervals during the trial, and infiltrating immune cells, CD3, CD4, CD8, CD1a and CD68, were evaluated by double immunocytochemical alkaline phosphatase antialkaline phosphatase (APAAP) staining. RESULTS: Our trial provided a complete cure rate of nine of 15 subjects after five PDT sessions. Perianal lesions showed a particularly rapid remission. While progressing towards total lesion clearance, the immunohistochemical pattern was dominated by dense CD4+ T lymphocytes infiltrating the superficial dermis, accompanied by an accumulation of Langerhans cells. Simultaneously, CD8 began to increase in the lesions of responding patients, and Langerhans cells seemed to migrate towards the dermis. CD68+ macrophages apparently did not participate in the immune inflammatory response. CONCLUSIONS: This study, to the best of our knowledge, represents the first attempt to clarify the effect of ALA-PDT on infiltrating immune cells in condylomata acuminata. Our results appear to confirm previously reported clinical data, suggesting that rapid activation of specific immunity in lesional skin, CD4+ T lymphocytes and dendritic cells could be responsible for healing.

Delayed Auditory Brainstem Responses (ABR) in children after sight-recovery.

Studies in non-human animal models have revealed that in early development, the onset of visual input gates the critical period closure of some auditory functions. The study of rare individuals whose sight was restored after a period of congenital blindness offers the rare opportunity to assess whether early visual input is a prerequisite for the full development of auditory functions in humans as well. Here, we investigated whether a few months of delayed visual onset would affect the development of Auditory Brainstem Responses (ABRs). ABRs are widely used in the clinical practice to assess both functionality and development of the subcortical auditory pathway and, provide reliable data at the individual level. We collected Auditory Brainstem Responses from two case studies, young children (both having less than 5 years of age) who experienced a transient visual deprivation since birth due to congenital bilateral dense cataracts (BC), and who acquired sight at about two months of age. As controls, we tested 41 children (sighted controls, SC) with typical development, as well as two children who were treated (at about two months of age) for congenital monocular cataracts (MC). The SC group data served to predict, at the individual level, wave latencies of each BC and MC participant. Statistics were performed both at the single subject as well as at the group levels on latencies of main ABR waves (I, III, V and SN10). Results revealed delayed response latencies for both BC children compared with the SC group starting from the wave III. Conversely, no difference emerged between MC children and the SC group. These findings suggest that in case the onset of patterned visual input is delayed, the functional development of the subcortical auditory pathway lags behind typical developmental trajectories. Ultimately results are in favor of the presence of a crossmodal sensitive period in the human subcortical auditory system.

Hypoxic events during non-obstetric abdominal surgery in pregnant women.

OBJECTIVE: Every year 0.5-2% of women undergo non-obstetric surgery in pregnancy. Hypoxic events with short-term and long-term consequences are one of the most frequent complications in surgery. There is only limited data available regarding the impact of these events. This review aims to analyze the current literature on hypoxic events occurring in non-obstetric abdominal surgery in pregnant women, focused on maternal and fetal outcomes. MATERIALS AND METHODS: We performed a non-systematic review of the literature, through a PubMed search using the key words "hypoxemia", "non-obstetric surgery", "surgical procedures", "pregnancy", "pregnant women" and "outcome". RESULTS: There is little data available regarding maternal and fetal outcomes after hypoxic episodes during non-obstetric surgery in pregnancy. In these cases, conservative intrauterine resuscitation maneuvers or immediate delivery should be taken into account. Perimortem cesarean section can be lifesaving for both mother and fetus when maternal collapse is non responsive to resuscitation procedures. Inaccurate information regarding maternal and fetal outcomes is due to the lack of robust data and the heterogeneity of the causes underlying maternal respiratory complications during surgery. CONCLUSIONS: Non-obstetric surgery during pregnancy must be performed when indicated. An expert multidisciplinary team, composed of obstetricians, surgeons, and anesthesiologists need to be included, giving appropriate attention to the physiological changes of respiratory, cardiovascular, and gastrointestinal system that occur during pregnancy. The shortest operative time and peri-operative assistance should be ensured. Complications, such as hypoxic events in pregnant patients need adequate assistance. Multidisciplinary cooperation, continuous training and simulation for anesthesiology and resuscitative procedures can guarantee this.

Pregnancy outcome in systemic lupus erythematosus complicated by anti-phospholipid antibodies.

OBJECTIVE: Pregnant women affected by SLE are at high risk of gestational hypertension and pre-eclampsia (32-50%). This risk is particularly elevated if aPLs are dosable. The present study was planned to evaluate maternal-fetal outcomes of different groups of SLE pregnant patients characterized by diverse risk factors: patients affected by APS treated with a combination of low-dose aspirin (LDA) and low-molecular weight heparin (LMWH), nulliparous patients with dosable aPL treated by LMWH and SLE patients with no aPL administered no treatment during pregnancy. METHODS: A retrospective description of maternal and fetal outcomes was made in a total of 62 pregnancies presenting APS in 8 cases (12.9%), aPL in 20 (32.2%) and no aPL in 34 (54.8%). RESULTS: No statistically significant difference was found comparing fetal and maternal outcomes of the three groups despite differences in SLE activity: SLE aPL-positive pregnancies were associated with a higher incidence of nephritis and chronic hypertension than pregnancies treated for APS or not presenting with the added risk factor. The incidence of pre-eclampsia is 15% in aPL positive, 12.5% in APS and 14.7% in no aPL pregnancies, respectively. CONCLUSIONS: LMWH is rather a possible option of prophylaxis for SLE aPL-positive pregnancies with potential maternal-fetal outcomes similar to aPL-negative patients or to standard treated APS.

Quantity, distribution and immunophenotypical modification of dendritic cells upon biological treatments in psoriasis.

Psoriasis is an immune-mediated disease which affects a large world population. It has long been considered a dermatological disorder in which keratinocytes and lymphocytes play a relevant pathogenic role. The aim of our study is to more closely observe and better define the role of dendritic cells (DCs) in psoriasis. We made a comparative analysis of the antigenic profile and the number, by immunohistochemical and electron microscopical study, of skin biopsy samples from psoriatic patients before and 4 months after biological treatments. Our results demonstrate an abundant distribution of activated DCs in lesional skin of psoriatic plaques and a marked decrease after biological therapies, a decrease of 70 percent for Langerhans cells (LCs) and mature myeloid dendritic cells (mDCs) and of 50 percent for plasmocytoid dendritic cells (pDCs). Both previous reports and the results of the present study support an underlying persistent immune response involving DCs in the onset and persistence of psoriasis. As DCs play a pivotal role in pathogenesis of psoriasis by presenting antigens via major histocompatibility complex class (MHC) II molecules, the present study supports the view that biological therapies are also effective in clearing psoriatic lesions as well as in reducing the number of DCs.

Malignant tumors of intraoral minor salivary glands.

Between 1995 and 2004, 43 patients with intraoral minor salivary gland carcinomas were diagnosed and treated at the Department of Maxillofacial Surgery, University of Parma, Italy. The palate was the most common site of involvement and comprised 53.5% of the cases. Adenoid cystic carcinoma was the most common histological type (60.6%), followed by mucoepidermoid carcinoma (27.9%). All patients were treated with surgery as the primary modality. Neck dissection was performed in 20.9% of patients, and more than half (72.1%) were treated with adjuvant radiation therapy. The range of the follow-up was 24-132 months (mean: 66 months). Of the 43 patients examined in this study, 12 died due to the tumor. Treatment failure was documented in 18 of the 43 patients (41.9%). Disease-free intervals ranged from 1 month to 9 years and 13.9% of the patients had local failure, whereas 25,6% had distant metastases. The survival rates at 2, 5, and 10 years were 90.7%, 71.8%, and 68%, respectively. The local control rates were 93.1% at 2 years and 83.1% at 5 and 10 years. The 2-, 5-, and 10-year rates for freedom from distant relapse were 95.2%, 83.4%, and 57.5%, respectively. The T stage, cervical lymph node metastasis, surgical margin status and perineural invasion were statistically significant to the outcome.

Profound hypokalemia and hypochloremic metabolic alkalosis during thiazide therapy in a child with Pendred syndrome.

Pendred syndrome is a recessive autosomal disorder characterized by thyroid goiter and sensorineural hearing loss. The Pendred syndrome gene (SLC26A4) encodes a new anion exchanger named pendrin which mediates iodide transport by thyrocytes and regulates ion and fluid transport by the endolymphatic sac epithelium. Pendrin defects result in inner ear malformations, with enlargement of the endolymphatic sac and duct in association with a large vestibular aqueduct. Furthermore, patients may develop endolymphatic hydrops requiring diuretic therapy, mainly in the form of thiazides. Pendrin could also account for apical Cl(-)/ HCO3(-) exchange at level of intercalated cells of the cortical collecting duct in the kidneys, however, humans with Pendred syndrome have no symptoms attributable to renal pendrin abnormalities in basal conditions. We report the case of a child with Pendred syndrome and intercurrent endolymphatic hydrops, who developed profound hypokalemia and severe hypochloremic metabolic alkalosis (potassium 1.7, chloride 70, sodium 129, HCO3 43.8, base excess +17.8 mmol/l, pH 7.52) following thiazide therapy. In subjects with Pendred syndrome thiazide therapy seems to provoke more severe Cl(-) and extracellular volume depletion. A possible explanation could be the defective action of the disrupted pendrin, which exacerbates the effects of the inhibition of C1(-) reabsorption mediated by the thiazide-sensitive NaCl cotransporter (SLC12A3).

Free and locoregional flap associations in the reconstruction of extensive head and neck defects.

Head and neck surgical defects after oncological resection of advanced carcinoma involving the oral cavity are often composite and involve bone, mucosa, soft tissues and skin. For the most extensive defects, the simultaneous association of two free flaps is the best choice to improve the function of the preserved structures. This procedure is difficult and involves prolonged surgery, therefore it is only possible in selected patients. In some composite head and neck defects the association of free and locoregional flaps seems to be indicated. This study, discusses the use of free and locoregional flap association, focusing on its aesthetic advantages and functional results. From January 1995 to December 2006, 30 patients received simultaneous locoregional and free flap transfer for closure of post-ablative oral cavity defects. Microvascular tissue transfer included the radial forearm, anterolateral thigh, rectus abdominis, and fibula and iliac crest free flaps. Locoregional flaps included the cervicofacial, cervicopectoral, deltopectoral, pectoralis major, latissimus dorsi and posterior scalp flaps. Based on the good functional and aesthetic outcome and low rate of complications, the association of free and locoregional flaps represents a good reconstructive option for patients with extensive post-oncological composite head and neck defects.

TRPV1 receptors in the CNS play a key role in broad-spectrum analgesia of TRPV1 antagonists.

Vanilloid receptor type 1 (TRPV1) is a ligand-gated nonselective cation channel that is considered to be an important integrator of various pain stimuli such as endogenous lipids, capsaicin, heat, and low pH. In addition to expression in primary afferents, TRPV1 is also expressed in the CNS. To test the hypothesis that the CNS plays a differential role in the effect of TRPV1 antagonists in various types of pain, the analgesic effects of two TRPV1 antagonists with similar in vitro potency but different CNS penetration were compared in vivo. Oral administration of either A-784168 (1-[3-(trifluoromethyl)pyridin-2-yl]-N-[4-(trifluoromethylsulfonyl)phenyl]-1,2,3,6-tetrahydropyridine-4-carboxamide) (good CNS penetration) or A-795614 (N-1H-indazol-4-yl-N'-[(1R)-5-piperidin-1-yl-2,3-dihydro-1H-inden-1-yl]urea) (poor CNS penetration) blocked capsaicin-induced acute pain with the same potency. In complete Freund's adjuvant (CFA)-induced chronic inflammatory pain, oral administration of either compound blocked thermal hyperalgesia with similar potency. Furthermore, intraplantar or intrathecal administration of A-784168 blocked CFA-induced thermal hyperalgesia, suggesting that both peripheral and CNS TRPV1 receptors may play a role in inflammatory thermal hyperalgesia. The effects of the two TRPV1 antagonists were further assessed in models presumably mediated by central sensitization, including CFA- and capsaicin-induced mechanical allodynia and osteoarthritic pain. In these models, the potency of the two compounds was similar after intrathecal administration. However, when administered orally, A-784168, with good CNS penetration, was much more potent than A-795614. Together, these results demonstrate that TRPV1 receptors in the CNS play an important role in pain mediated by central sensitization. In addition, these results demonstrate that significant CNS penetration is necessary for a TRPV1 antagonist to produce broad-spectrum analgesia.

Routine determination of benzo[a]pyrene at part-per-billion in complex industrial matrices by multidimensional liquid chromatography.

A rapid and selective high performance liquid chromatography (HPLC) method using a column-switching technique has been developed for the determination of benzo[a]pyrene in complex mixtures containing polycyclic aromatic hydrocarbons. The diluted sample is directly injected into the chromatographic system without pre-treatment. The purification is performed on-line using three cleaning columns filled with various stationary phases. The sample preparation, a simple dilution, and the analysis time do not exceed 45 min. The method developed was used to analyze industrial products such as oil, bitumen, etc. and was compared with an off-line method requiring treatment and extraction steps before the analysis.

Respiratory symptoms and bronchial responsiveness among cleaning and disinfecting workers in the food industry.

OBJECTIVES: To measure the levels of exposure to nitrogen trichloride (NCl3) and aldehydes among cleaning and disinfecting workers in the atmosphere of food industry plants during cleaning and disinfecting operations, and to examine how they relate to irritant and chronic respiratory symptoms-which are indices of pulmonary function-and bronchial hyperresponsiveness (BHR) to methacholine. METHODS: 175 exposed workers (M = 149; F = 26) recruited from 17 enterprises of the food industry (8 cattle, pig, and ovine slaughterhouses, 8 fowl slaughterhouses, and 1 catering firm) and 70 non-exposed workers (M = 52; F = 18) were examined. Concentration levels of NCl3 and aldhehydes were measured by personal sampling. Symptoms were assessed by means of a questionnaire and the methacholine bronchial challenge (MBC) test using an abbreviated method. Subjects were labelled MBC+ if forced expiratory volume in one second (FEV1) fell by 20% or more. The linear dose-response slope (DRS) was calculated as the percentage fall in FEV1 at last dose divided by the total dose administered. RESULTS: 277 air samples were taken in the 17 food industry plants. For a given plant and in a given workshop, the actual concentrations of chloramines, aldehydes, and quaternary ammonium compounds were measured with personal samplers during the different steps of the procedures. For each cleaner, a total exposure index Sigma was calculated. A statistically significant concentration-response relationship was found between eye, nasal, and throat symptoms of irritation--but not chronic respiratory symptoms--and exposure levels or exposure duration. No relation was found between BHR and exposure. CONCLUSIONS: These data show that cleaning and disinfecting workers in the food industry are at risk of developing eye, nasal, and throat irritation symptoms. Although NCl3 exposure does not seem to carry a risk of developing permanent BHR, the possibility of transient BHR cannot be ruled out entirely.

The submental island flap in head and neck reconstruction.

The authors describe their experience with the submental island flap for the primary correction of head and neck deformities following oncologic surgery, over the past 5 years. The use of this flap is reported in 12 patients, with a mean age of 67 years, requiring facial or intraoral reconstruction. A brief review of the key points and some refinements in the operative technique are discussed. The reconstruction of defects with a submental island flap was successful in every patient. Complications encountered were one case of temporary palsy of the marginal mandibular branch of the facial nerve and one case of orocutaneous fistula. All the donor site defects were closed primarily. The submental island flap is an excellent choice for the reconstruction of head and neck defects because of its reliability, versatility, colour and texture match, and relative ease of application.

Masseteric nerve for gracilis muscle re-innervation in unilateral facial palsy: Impact on quality of life.

BACKGROUND: Unilateral established or congenital facial palsies are usually treated with neuromuscular transplantation to reanimate the impaired side of the face. One of the most debated points is the motor nerve to choose for the reinnervation of the transplant. Contra-lateral healthy facial nerve is usually preferred, but in selected cases motor nerve to masseter is considered a valuable option. However only a few clinical studies focused on quality of life in this subset of patients are available in literature. METHODS: Twenty patients treated for established or congenital unilateral facial palsy reanimated with gracilis muscle transplant reinnervated with masseteric nerve were retrospectively analyzed. The FDI questionnaire on quality of life was administered before and after surgery and statistical analysis of results was conducted to score changes. RESULTS: Overall results of the questionnaire resulted in a statistically significant improvement after surgery, with a p value of 0.05. CONCLUSION: Facial animation with gracilis muscle transplant re-innervated with masseteric nerve is a safe and reliable procedure in selected unilateral facial palsy patients. Results reported here confirm that surgery mainly improves the functional aspects of a patient's daily life quality, while the impact on social interactions and self-perception is less significant. The comparison of these results with those obtained in patients treated with gracilis muscle transplant re-innervated via contralateral facial nerve suggests that spontaneity is probably highly relevant to improve social aspects of QOL in this subset of patients.
