RESUMEN

PURPOSE: To evaluate the clinical and aesthetic outcome of percutaneous injection of sclerosant agents to treat head and neck cystic malformations (HNCM) and to assess their recurrence rate based on histology and site. METHODS: Fifty-four subjects (mean age 46 years) with HNCM treated by percutaneous injection of sclerosant agents between January and December 2017 were included. Imaging and clinical data before and after the procedure were collected. Quality of Life Index, Pain Visual Analogue Scale, and Aesthetic Scale scores were measured to assess clinical and aesthetic outcomes. A size reduction of ≥ 70% assessed through the visual scale was considered significant. RESULTS: Of the 54 HNCM, there were 26 (48%) lymphatic malformations (LM), 13 (24%) salivary epithelial duct cysts of the parotid gland, 12 (22%) salivary mucoceles, and 3 (5%) branchial cysts. A significant size reduction and a satisfactory clinical-aesthetic outcome were observed in all types of LM. The number of reinterventions was significantly associated with the number of lesions (p < 0.001). The lowest number of interventions was observed in macrocystic lymphatic malformations (average of 1.2 interventions). All salivary epithelial duct cysts showed a significant reduction in size, a satisfactory clinical-aesthetic outcome, and an average of 1.16 interventions per patient. Mucoceles had a worse response, with only 3/14 patients showing a satisfactory and long-lasting clinical outcome (average of 1.16 interventions). Treatment of branchial cysts showed the worst outcome with a limited clinical response (3/3). CONCLUSION: Percutaneous injection of sclerosant agents may be considered as a first-line treatment for LM and salivary epithelial duct cysts.

RESUMEN

PURPOSE: After maxillary osteotomy in orthognathic surgery, patients report nasal breathing discomfort in early postoperative period. Topical hyaluronic acid (HA) has been proven to have beneficial effects on the upper airway tract mucosa. This prospective randomized controlled study was designed to analyze the effect on nasal obstruction of nebulized HA during the recovery process after maxillary osteotomy. METHODS: Patients were randomized to control and treatment groups. The postoperative treatment differed only for additional nebulized HA provided to the treatment group. The level of nasal obstruction, and its impact on quality of life, was assessed every 3 days for the first 15 days postoperatively using a questionnaire. Demographic and other variables (maxillary osteotomy type and surgical movements) were analyzed. Differences in quantitative data were tested using Student's t-test, the Mann-Whitney U test, and mixed repeated measures ANOVA. RESULTS: Twenty-four subjects were included in each group; differences in age, sex, type of maxillary osteotomy, and movements were non-statistically significative. At the beginning of treatment (T0), the two groups had comparable questionnaire scores regarding nasal breathing discomfort (p >0.05), whereas statistically significant differences were found at days 3, 6, 9, and 12 (p <0.05). A significant decrease in nasal breathing discomfort over time was observed in both groups, with trends that differed between the two, indicating faster improvement in the treatment group. CONCLUSION: Nebulized HA can be a useful additional treatment in early postoperative period after orthognathic surgery. Patients reported more rapid improvement of nasal respiratory symptoms, indicating a potential role for HA in reducing recovery time and patient discomfort after maxillary surgery.

RESUMEN

A surgical site infection (SSI) is an infection that occurs in the incision created by an invasive surgical procedure. Although most infections are treatable with antibiotics, SSIs remain a significant cause of morbidity and mortality after surgery and have a significant economic impact on health systems. Preventive measures are essential to decrease the incidence of SSIs and antibiotic abuse, but data in the literature regarding risk factors for SSIs in the pediatric age group are scarce, and current guidelines for the prevention of the risk of developing SSIs are mainly focused on the adult population. This document describes the current knowledge on risk factors for SSIs in neonates and children undergoing surgery and has the purpose of providing guidance to health care professionals for the prevention of SSIs in this population. Our aim is to consider the possible non-pharmacological measures that can be adopted to prevent SSIs. To our knowledge, this is the first study to provide recommendations based on a careful review of the available scientific evidence for the non-pharmacological prevention of SSIs in neonates and children. The specific scenarios developed are intended to guide the healthcare professional in practice to ensure standardized management of the neonatal and pediatric patients, decrease the incidence of SSIs and reduce antibiotic abuse.

RESUMEN

Surgical site infections (SSIs) represent a potential complication in surgical procedures, mainly because clean/contaminated surgery involves organs that are normally colonized by bacteria. Dental, maxillo-facial and ear-nose-throat (ENT) surgeries are among those that carry a risk of SSIs because the mouth and the first respiratory tracts are normally colonized by a bacterial flora. The aim of this consensus document was to provide clinicians with recommendations on surgical antimicrobial prophylaxis in neonates (<28 days of chronological age) and pediatric patients (within the age range of 29 days−18 years) undergoing dental, maxillo-facial or ENT surgical procedures. These included: (1) dental surgery; (2) maxilla-facial surgery following trauma with fracture; (3) temporo-mandibular surgery; (4) cleft palate and cleft lip repair; (5) ear surgery; (6) endoscopic paranasal cavity surgery and septoplasty; (7) clean head and neck surgery; (8) clean/contaminated head and neck surgery and (9) tonsillectomy and adenoidectomy. Due to the lack of pediatric data for the majority of dental, maxillo-facial and ENT surgeries and the fact that the recommendations for adults are currently used, there is a need for ad hoc studies to be rapidly planned for the most deficient areas. This seems even more urgent for interventions such as those involving the first airways since the different composition of the respiratory microbiota in children compared to adults implies the possibility that surgical antibiotic prophylaxis schemes that are ideal for adults may not be equally effective in children.

RESUMEN

BACKGROUND: The choice of neurotization source for gracilis neuromuscular transplant is a key point in the treatment of unilateral long-standing paralysis. To combine the advantages of different donor nerves and overcome their disadvantages, mixed neurotization sources have been described with encouraging results. The authors present a preliminary report of a novel technique, the "supercharged" cross-graft, a two-step technique consisting of a double powered cross nerve graft provided by a zygomatic branch of the healthy facial nerve and the masseter nerve of the healthy side. PATIENTS AND METHODS: From January 2015 to December 2019 eight patients, aged between 19 and 61 years old (mean age at surgery 33.62) suffering unilateral established paralysis (congenital or acquired, >24 months) underwent gracilis reinnervation with the supercharged cross grafting technique. Subjects underwent a two-step surgical rehabilitation: in the first operation sural nerve was harvested and used as cross-graft cooptated by healthy side facial nerve branch and masseteric nerve. During second procedure gracilis neuromuscular transplant was performed reinnervarting the muscle with the cross-graft. Patients were evaluated using Emotrics software, which allowed for automated facial measurements on post-operative pictures taken at the last follow-up. The results of the different poses were compared to assess the contribution to smile excursion by the masseter and facial nerve, together and separately. Finally, we analyzed spontaneous smile to assess whether masseteric contribution is used in daily life. RESULTS: No major or minor complications occurred. Follow-up time ranged from 12 to 41 months, with a mean of 22.75 months. A good commissure excursion (mean 33.84 mm) was obtained during smile with no teeth clenching (without masseter activation), as well as during teeth clenching without smiling (activation of gracilis only - mean 32.55). When smiling and biting simultaneously the excursion was greater than the single two components (mean 35.91). In spontaneous smile, commissure excursion was higher (mean 34.23) than that provided by only the facial nerve (smile only) in most patients. CONCLUSIONS: This novel technique of mixed neurotization for gracilis transplant shows consistent results with powerful contraction and good smile coordination. It also allows us to extend the indications for mixed neurotization techniques.

RESUMEN

Duplication of the pituitary gland (DPG)-plus syndrome is a very rare developmental disorder with few cases described in the literature and characterized by multiple midline and central nervous system malformations. The hypothalamus and hypophysis involvement may be clinically associated with endocrine abnormalities. A 5.9-year-old female child was admitted to our Clinic for premature thelarche and acceleration of growth. DPG-plus syndrome with paired infundibula and pituitary glands was diagnosed after birth, when she appeared small for gestational age and she presented with lingual hypoplasia, cleft palate, right choanal stenosis, nasopharyngeal teratoma, and facial dysmorphisms. Neuroimaging revealed a duplication of the infundibula, the pituitary gland, and the dens of the epistropheus despite surgical removal of a rhino-pharyngeal mass performed at the age of two months. An array-CGH revealed a 2p12 deletion. At our evaluation, bone age assessment resulted advanced and initial pubertal activation was confirmed by Gonadotropin-Releasing Hormone stimulation test. Hormonal suppression treatment was started with satisfactory results. This case shows that DPG-plus syndrome must be considered in presence of midline and craniofacial malformations and endocrinological evaluations should be performed for the prompt and appropriate management of pubertal anomalies.

RESUMEN

PURPOSE: Purpose of the article is to discuss the use of the scapular tip free flap (STFF) for the reconstruction of maxillary defects. METHODS: A retrospective evaluation of patients who underwent maxillary reconstruction with STFF is presented. Patients were evaluated with respect to complications, function, and cosmesis. RESULTS: Study population consisted of 53 patients. All flaps survived and partial bone resorption only occurred in a young patient. Minor complications included two instances of partial muscular necrosis. The donor site was primarily closed in all patients. Mouth opening was assessed as good (>3 cm) in 41 patients, partially limited (2-3 cm) in 9 patients, and limited (<2 cm) in 3 patients. Dental rehabilitation was achieved in 35 patients; esthetic results were assessed by patient as excellent in 19 patients, good in 28 patients, and poor in 6 patients. CONCLUSIONS: The scapular tip chimeric free flap represents an indispensable tool for reconstructive head and neck microsurgery. The main advantages of this technique are very low donor site morbidity and a long pedicle, as well as the potential for harvesting multiple flaps in a chimeric design; STFF represents the first choice for treatment of small postero-lateral defects of the maxilla, and of wide and complex through-and-through defects involving all components of the midface.

RESUMEN

BACKGROUND: Severe microretrognathia with the absence of ascending mandibular ramus is a challenging deformity and treatment must aim to avoid tracheostomy or remove it as soon as possible. Although it is not often reported, mandibular distraction osteogenesis represents a valid treatment option in infants affected by hypoplastic mandible Pruzansky-Kaban type IIb and III. CASE PRESENTATION: The authors describe 3 cases of infants affected by severe respiratory insufficiency due to congenital mandibular hypoplasia, with follow up ranging from 4 to 8 years. Clinical and technical considerations on treatment choices and outcomes are discussed starting from review of the literature and direct clinical experience. CONCLUSION: Early mandibular distraction, specifically bidirectional distraction, is an effective and repeatable technique that leads to mandible lengthening with counterclockwise rotation, pogonion projection increase, anteropositioning of the tongue base, and expansion of oropharyngeal volume with positive effect on the respiratory problems of the infant. Even in Treacher Collins patients, known to have a low decannulation rate, all of these elements are essential for effective speech and swallowing therapy and for a subsequent attempt of decannulation.

RESUMEN

Gracilis neuromuscular transplant is considered the gold standard for facial animation in Moebius syndrome patients. However, long-term evaluation of the results has not been critically examined in the international literature. Thus, it remains unknown how the transplanted flap changes with facial growth, and whether contraction (smiling) is maintained. Pediatric patients with Moebius syndrome who underwent facial animation surgery with at least 5 years of follow-up were retrospectively examined. Photographs taken at the 1-year and most recent follow-up visits were analyzed and compared using Emotrics software. Analyses focused on the rest position, and on gentle and maximum smiles. Eighteen patients were enrolled. Seven patients had bilateral and 11 unilateral Moebius syndrome; therefore, 25 gracilis transplants were analyzed. The latest follow-ups ranged from 5 to 13.2 years (mean 7.6 years). The three principal facial expressions that were examined did not differ significantly between 1 year and a mean of 7.6 years after surgery, but tended to improve in most patients. Commissure excursion and smile angle for the maximum smile did improve significantly (p = 0.002 and 0.029, respectively). The series examined in this study supports the limited literature regarding the long-term stability of gracilis transplantation to animate the faces of Moebius syndrome children.

RESUMEN

Purpose of the present study is to objectively evaluate the number of severe vascular complications, represented by skin necrosis and vision loss or impairment, following facial filler injection. The investigators implemented a review of the literature including articles published on PubMed database without limitation about year of publication, including all reports concerning skin necrosis and vision loss or impairment related to the injection of fillers for cosmetic uses. The search highlighted 45 articles and a total of 164 cases of skin necrosis and vision loss or impairment after injection of different substances. The injection site most frequently associated with complications was the nose (44.5%), followed by glabella (21%), nasolabial fold (15%), and forehead (10%). Results of the present study suggest that injectable filler can cause severe complications even in expertized hands. Treatments in the new defined "Dangerous triangle" must be carefully carried out. Despite our expectations, the highest rates of sever adverse events have been associated with autologous fat transfer practice.

RESUMEN

The aim of this retrospective case series was to discuss indications, surgical outcomes, and donor site morbidity in the use of superficial temporal artery perforator (STAP) flaps in intra-oral or extra-oral facial reconstruction. This study involved 9 patients treated with a STAP flap at the Maxillo-Facial Surgery Unit of the University of Campania "Luigi Vanvitelli", Naples. A STAP flap was used alone or in combination with other local flaps, for the coverage of facial soft tissue defects, after the resection of craniofacial malignant tumors (n = 7) or as a salvage flap, in partial or total microvascular flap loss (n = 2). The STAP flap was proven to be a valuable surgical option despite it not being frequently used in facial soft tissue reconstruction nor was it chosen as the first surgical option in patients under 70 year's old. Donor site morbidity is one of the major reasons why this flap is uncommon. Appropriate patient selection, surgical plan, and post-surgical touch-ups should be performed in order to reduce donor site scar morbidity.

RESUMEN

AIM: To compare the most important techniques usually used in these patients. MATERIALS AND METHODS: A multicentric retrospective evaluation on patients treated for cT1/2 N0 OTFOM SCC was conducted; patients in group A were treated by transoral approach and miomucosal local flap while those in group B were treated by pull-through and free flap reconstruction. Oncologic, functional and quality of life evaluation was assessed. RESULTS: 55 patients were enrolled. Group A consisted of 35 patients and group B 20. At the 3-year follow-up 30 and 17 patients in group A and B were alive without disease. Tongue mobility index score was 23.3 in group A and 13.89 in group B (p < .001); Sydney swallowing mean score was 118.5 and 543.22 in group A and B (p < .001). EORTC QLC-C30 was of 33.57 in group A and 38.89 in group B (p = 0.057). CONCLUSION: T1/T2 cancers of the tongue and floor of the mouth can be equally treated with both techniques. Because of the fact that transoral resection with buccinators reconstruction provides better functional outcome, this technique should be preferred whenever appropriate.

RESUMEN

Skin necrosis is the most severe complication arising from hyaluronic acid (HA) injection. To avoid skin necrosis, hyaluronidase should be injected along the course of the involved artery, to allow blood flow restoration. We evaluated the ability of hyaluronidase to degrade a HA filler in two simulated clinical situations-a compression case and an embolization case-to identify differences in the hyaluronidase injection. In the compression case, a bolus of HA filler was directly soaked in hyaluronidase solution; in the embolization case, a vein harvested from a living patient was filled with the same HA filler and then soaked in hyaluronidase. We then evaluated the quantity of HA remaining after 2 hr. While we found hydrolysis of HA in both cases, in the compression case, we detected almost complete hydrolysis, whereas in the embolization case we observed a reduction of the 60%. Our results support the hypothesis that vessel compression can be resolved with only one injection of hyaluronidase, while in the case of vascular embolization, repeated perivascular injections should be performed owing to the reduction of hyaluronidase activity.

RESUMEN

Vascular malformations are often found inside the orbit. Isolated venous malformations (frequently misnamed as cavernous hemangiomas) are the most frequent among these. However, also lymphatic and arteriovenous malformations can affect the orbit. The complex anatomy of the orbit and the fact that its content easily suffers from compartmental syndrome explain why treating orbital vascular malformations can be challenging and technically demanding. In this study, two institutions have retrospectively collected their cases, consisting in a total of 69 vascular malformations of the orbit. Each type of malformation has been evaluated separately in terms of diagnosis, indications for treatment, techniques and outcomes. Moreover, the authors have analyzed in detail venous malformations, identifying three different types, named orbital venous malformation (OVM) 1, 2 and 3. These behave differently from each other, and a prompt differential diagnosis is mandatory to pose correct indications, minimize risks and improve results. Overall, surgery was the technique of choice for OVM1, microcystic lymphatic malformations (LM) and arteriovenous malformations (AVM). A pure transnasal approach with mass removal and reconstruction of the medial wall with polyethylene sheets was chosen for OVM1 (intra- or extraconal) located in the medial or superomedial compartment. Sclerotherapy had a role in treating macrocystic LM and OVM3.

RESUMEN

BACKGROUND: Fibular donor site pain management in the early postoperative period can help minimize complications, patient discomfort, and agitation. Traditional management of postoperative pain consists of systemic administration of opioids and NSAIDS. The use of local anesthetics in addition to systemic analgesics has the potential to improve pain control. Purpose of the study is to evaluate the efficacy of mini-catheters used to inject local anesthetic into the fibular donor site after flap harvesting for reconstruction of the head-and-neck area. METHODS: Prospective study on 31 patients (mean age 52 years) treated for head and neck reconstruction with fibula free flap using minicatheter for local anesthetic injection in the early postoperative time. A bolus of chirochaine (0.125% w/v; 20 mL) was injected through the catheter before the patient regained consciousness. Postoperatively, three consecutive injections (20 mL each) were administered 8, 16, and 24 h after surgery. Pain evaluation before and after local anesthetic injection is used to assess efficacy and overall pain control. RESULTS: No major or minor complication occurred. Mean pain value was 1.69. At 8 h, the pain scores before injection ranged from 0 to 10 (mean 4.13 ± 3.06). After injection, the pain scores ranged from 0 to 5 (mean 1 ± 1.34). Similarly, at 16 h, the pain scores ranged from 0 to 8 (mean 2.77 ± 2.42) before injection and from 0 to 6 (mean 0.42 ± 1.2) thereafter. At 24 h, the initial pain score ranged from 0 to 6 (mean 1.71 ± 1.74) and from 0 to 1 (mean 0.1 ± 0.3) after drug administration. Pre and postinjection pain scores differences were statistically significant after all three injections (P < .001). CONCLUSIONS: Minicatheter seems to be easy, safe, and efficient when used to control pain after fibular free-flap harvesting.

RESUMEN

Iatrogenic injury in oral surgery is the most frequent cause of sensory disturbance in the distribution of the inferior alveolar nerve (IAN) and mental nerve.Inferior alveolar nerve damage can occur during third molar extraction, implant location, orthognathic surgery, preprosthetic surgery, salivary gland surgery, local anesthetic injections or during the resection of benign or malignant tumors.Injuries to the IAN can be caused also by endodontic treatment of mandibular molars and premolars when filling material is forced into the tooth and mandibular canal.The sensory disturbances that could follow a damage of the IAN could be hypoesthesia, dysesthesia, hyperesthesia, anesthesia, and sometimes a painful anesthesia that strike ipsilateral lower lip, chin, and teeth. These can undermine life quality by affecting speech, chewing, and social interaction.Treatment of these complications is sometimes difficult and could consist in observation or in surgical decompression of the involved nerve to relieve the patient's symptoms and improve sensory recovery. The most debated points are the timing of intervention and the effective role of decompression in clinical outcome-improvement.The purpose of this article is to show authors' experience with 2 patients treated with microsurgical nerve decompression to remove endodontic material from the mandibular canal and providing also a comprehensive review of the literature.

RESUMEN

BACKGROUND: The mainstay of treatment in adenoid cystic carcinoma (ACC) of the head and neck is surgical resection with negative margins. The purpose of this study was to define the margin status that associates with survival outcomes of ACC of the head and neck. METHODS: We conducted univariate and multivariate analyses of international data. RESULTS: Data of 507 patients with ACC of the head and neck were analyzed; negative margins defined as ≥5 mm were detected in 253 patients (50%). On multivariate analysis, the hazard ratios (HRs) of positive margin status were 2.68 (95% confidence interval [CI], 1.2-6.2; p = .04) and 2.63 (95% CI, 1.1-6.3; p = .03) for overall survival (OS) and disease-specific survival (DSS), respectively. Close margins had no significant impact on outcome, with HRs of 1.1 (95% CI, 0.4-3.0; p = .12) and 1.07 (95% CI, 0.3-3.4; p = .23) for OS and DSS, respectively, relative with negative margins. CONCLUSION: In head and neck ACC, positive margins are associated with the worst outcome. Negative or close margins are associated with improved outcome, regardless of the distance from the tumor. © 2017 Wiley Periodicals, Inc. Head Neck 39: 1008-1014, 2017.

RESUMEN

Inflammatory pseudotumor (IPT) is a rare benign mass-forming disease that can arise anywhere throughout the body, mimicking a wide spectrum of other conditions. Its diagnosis can be challenging, especially when it involves uncommon sites. The authors report a patient of an atypical localization of IPT, occurred as an enlarging bulk in the infraorbital nerve channel in a patient who presented with facial numbness. Clinical and radiological aspects similar to schwannoma led to misdiagnosis and over-treatment. The differential diagnosis of an infraorbital mass should include IPT and the least invasive treatment should be preferred, as steroid therapy being the first-line treatment for IPT.

RESUMEN

PURPOSE: To compare diagnostic performance between computed tomography (CT) and magnetic resonance imaging (MRI) for the detection of bone infiltration from oral cancer, and to test interobserver agreement between radiologists with different expertises. MATERIALS AND METHODS: Pre-surgical CT and MRI were reviewed independently by two radiologists with different expertises in head and neck oncology. A third radiologist reviewed CT and MRI simultaneously. Interobserver agreement was calculated by Cohen test. Association between radiological evidence of bone infiltration and histological reference was tested by Fisher's exact test or Chi-squared test, as appropriate. Receiving operator curve was calculated and area under the curve (AUC) was compared between CT, MRI, and both methods together. RESULTS: Interobserver agreement was moderate: the trainee under-reported periosteal reaction on CT and inferior alveolar canal involvement on MRI. Imaging findings associated with histologic evidence of bone infiltration were: periosteal reaction and cortical erosion on CT; bone marrow involvement, contrast enhancement within bone; and inferior alveolar canal involvement on MRI. Sensitivity of MRI alone (74 %) was higher than CT (52 %). Simultaneous review of CT and MRI showed the highest specificity (91 %), with the increase of diagnostic performance in the subgroup of subjects with positive MRI (AUC = 0.689; p = 0.044). CONCLUSION: Higher expertise allows pre-surgical detection of clinically relevant signs of bone infiltration sensitivity of MRI alone is higher than CT for the detection of bone infiltration from oral cancer. In MRI positive cases, diagnostic integration with combined review of CT and MRI is suggested for optimal diagnostic performance.

RESUMEN

PURPOSE: Gracilis muscle reinnervated by the contralateral facial nerve via cross-graft technique is nowadays considered to be a first-line procedure for facial animation in unilateral palsies. Despite the wide number of papers published analyzing technical aspects, refinements, functional results, and cosmetic outcomes, only a few authors have focused their publications on the patient's perspective and impact on QOL of these procedures. MATERIAL AND METHODS: Changes in quality of life in 42 patients treated with gracilis muscle transplant reinnervated via cross-face graft were analyzed through a comparison of preoperative and postoperative items on the Facial Disability Index questionnaire. Statistical evaluation with a paired t-test was performed concerning overall results and specific items modifications. RESULTS: Overall improvement of QOL was found to be highly significant (p = 0.001). Mouth and eye functions were the most improved (p = 0.001), whereas isolation (p = 0.004) and feeling calm and peaceful (p = 0.001) were the most improved among the social functions. CONCLUSIONS: Facial animation with gracilis neuromuscular transplantation reinnervated with contralateral healthy facial nerve via a cross-graft procedure has been demonstrated to be a safe and reliable procedure in the treatment of congenital or established facial palsies. Our results on quality of life impact support that these operations are not only reliable and safe but also of primary relevance to patients' everyday lives.
