Supercharged massetric-facial cross-graft for gracilis reinnervation in unilateral facial palsy treatment.

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.

Maxillary reconstruction with scapular tip chimeric free flap.

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.

Cross-linked hyaluronic acid filler hydrolysis with hyaluronidase: Different settings to reproduce different clinical scenarios.

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.

Skin Necrosis and Vision Loss or Impairment After Facial Filler Injection.

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.

Perioperative pain management after fibular free flap harvesting for head-and-neck reconstruction using mini-catheters to inject local anesthetic: A pilot study.

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.

Microsurgical Decompression of Inferior Alveolar Nerve After Endodontic Treatment Complications.

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.

Inflammatory Pseudotumor of the Infraorbital Nerve: A Rare Diagnosis to Be Aware of.

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.

Pre-surgical assessment of mandibular bone invasion from oral cancer: comparison between different imaging techniques and relevance of radiologist expertise.

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.

Elective neck dissection in patients with head and neck adenoid cystic carcinoma: an international collaborative study.

BACKGROUND: Adenoid cystic carcinoma (ACC) accounts for 3-5 % of all head and neck malignancies. Investigations of outcomes from elective neck dissection (END) for patients with ACC are sparse. This study aimed to assess the impact of END on the survival of patients with ACC. METHODS: This retrospective multicentered study investigated 270 patients who underwent neck dissection. A multivariate analysis assessed associations of clinical and histopathologic characteristics with survival outcomes. RESULTS: The primary tumor sites included the oral cavity in 250 patients (55 %), the major salivary glands in 133 patients (29 %), the sinonasal mucosa in 68 patients (15 %), and the larynx in six patients (1 %). The overall rate of occult nodal metastases among the patients who underwent END was 17 % (38/226). The highest incidence of occult nodal metastases was with the oral cavity (66 %). The 5-year overall survival (72 and 79 % for patients with or without END, respectively) and disease-specific survival (74 and 81 % for patients with or without END, respectively) were similar in the two groups. The subgroup analysis of patients according to the primary site showed no significant impact of END on outcome. In the multivariate analysis, primary site, T classification, and N classification were the only variables associated with outcome. CONCLUSIONS: The incidence of occult neck metastases among patients with ACC is 17 %. The highest incidence of occult metastases is with the oral cavity. Statistical analysis showed no survival advantage for patients who underwent END compared with those who did not.

Proteoglycan-based diversification of disease outcome in head and neck cancer patients identifies NG2/CSPG4 and syndecan-2 as unique relapse and overall survival predicting factors.

BACKGROUND: Tumour relapse is recognized to be the prime fatal burden in patients affected by head and neck squamous cell carcinoma (HNSCC), but no discrete molecular trait has yet been identified to make reliable early predictions of tumour recurrence. Expression of cell surface proteoglycans (PGs) is frequently altered in carcinomas and several of them are gradually emerging as key prognostic factors. METHODS: A PG expression analysis at both mRNA and protein level, was pursued on primary lesions derived from 173 HNSCC patients from whom full clinical history and 2 years post-surgical follow-up was accessible. Gene and protein expression data were correlated with clinical traits and previously proposed tumour relapse markers to stratify high-risk patient subgroups. RESULTS: HNSCC lesions were indeed found to exhibit a widely aberrant PG expression pattern characterized by a variable expression of all PGs and a characteristic de novo transcription/translation of GPC2, GPC5 and NG2/CSPG4 respectively in 36%, 72% and 71% on 119 cases. Importantly, expression of NG2/CSPG4, on neoplastic cells and in the intralesional stroma (Hazard Ratio [HR], 6.76, p = 0.017) was strongly associated with loco-regional relapse, whereas stromal enrichment of SDC2 (HR, 7.652, p = 0.007) was independently tied to lymphnodal infiltration and disease-related death. Conversely, down-regulated SDC1 transcript (HR, 0.232, p = 0.013) uniquely correlated with formation of distant metastases. Altered expression of PGs significantly correlated with the above disease outcomes when either considered alone or in association with well-established predictors of poor prognosis (i.e. T classification, previous occurrence of precancerous lesions and lymphnodal metastasis). Combined alteration of all three PGs was found to be a reliable predictor of shorter survival. CONCLUSIONS: An unprecedented PG-based prognostic portrait is unveiled that incisively diversifies disease course in HNSCC patients beyond the currently known clinical and molecular biomarkers.

Head and neck reconstruction using the superiorly based reversed-flow facial artery myomucosal flap.

PURPOSE: The use of myomucosal buccinator flaps in the reconstruction of oral cavity defects is well established in the international literature; however, their use for the reconstruction of defects not in the oral cavity has been largely underestimated. The purpose of this report was to describe and review the applications of the superiorly based facial artery myomucosal (FAMM) flap in head and neck reconstruction. MATERIALS AND METHODS: This study was a retrospective evaluation of 12 patients who underwent reconstruction of the palate, lip, nasal septum, and conjunctiva with reversed-flow FAMM flaps. Mouth opening, speech, reconstruction effectiveness, and esthetic outcomes were analyzed. RESULTS: The patient cohort consisted of 7 men and 5 women 33 to 80 years old (mean, 56.2 yr old). No major complication occurred. Cosmetic results were excellent in most patients. Functionally, the best reconstruction results were obtained in the palate, lip, and conjunctiva. Nasal reconstruction led to mild airway obstruction in 2 cases and severe obstruction in 1 case. CONCLUSION: The superiorly based FAMM flap plays an important role in the reconstruction of particular defects involving the oral cavity and other distant sites of the head and neck area. The reliability, low morbidity, and optimal results that can be achieved using this technique make this flap a good option for such reconstructions.

Donor site morbidity after scapular tip free flaps in head-and-neck reconstruction.

BACKGROUND: Recently, the scapular tip free flap has been popularized as a valuable option for bone reconstruction of the head and neck area. Analyses of perioperative and long-time morbidity are crucial to enable complete comprehension of this technique and will be presented in this paper. METHODS: Perioperative and long-term morbidity of scapular tip flaps harvesting were analyzed in a cohort of 19 patients. Local complications and ambulation-time were used to assess perioperative results, while Constant-Murley and DASH scores were used to evaluate long-term morbidity on shoulder functions. RESULTS: Local perioperative complications were minimal (three cases of seroma and two wound dehiscence). Ambulation time ranged between 2 and 4 days (mean 2.7 days). Constant-Murley scores ranged between 66 and 100 (mean 92.2). The DASH score ranged between 39 and 85 (mean 48.6). CONCLUSION: Harvesting a scapular tip free flap resulted in very low shoulder morbidity, without interfering the patient's daily activities. © 2015 Wiley Periodicals, Inc.

Reconstruction of mandibular defects using the scapular tip free flap.

PURPOSE: Purpose of the article is to present the use of the scapular tip free flap (STFF) for the reconstruction of oromandibular defects. PATIENTS: Eleven patients who underwent oromandibular reconstruction with STFF were retrospectively evaluated with regards to form and function assessing mouth opening, dietary intake, and cosmetic outcome. Donor site morbidity was evaluated using the Constant-Murley test for the shoulder unit. RESULTS: Follow-up ranged from 6 to 35 months (mean 20.6 months). Good or excellent results in mouth opening and cosmesis were achieved in eight patients, speech was assessed as intelligible or normal in all but one patient and mean ambulation time after surgery was 2.5 days. Results of Constant score ranged from 45 to 70 (mean 60.6), and the main limitation encountered was elevation of the arm above the head, which was seen in all but one patient confirming the low impact of the technique on the shoulder system. CONCLUSION: Low morbidity, early ambulation time, possibility of simultaneous harvesting with the tumor resection, large musculocutaneous paddles in the chimeric version of the flap are advantages of the STFF and makes it a good choice in elderly patients, when other bone containing free flaps are not indicated because of the related morbidity, when other flaps are not available or when wide composite defects are approached.

Neonatal mandibular distraction in a patient with Treacher Collins syndrome.

The purpose of this study was to analyze a case of mandibular distraction in a case of Treacher Collins syndrome. Mandibular distraction is an adequate surgical treatment of patients with Pierre Robin sequence and represents an alternative to tracheostomy. In severe hypoplastic cases or when three-dimensional vector control or gonial angle control is necessary, extraoral bidirectional or multidirectional devices have an advantage over intraoral devices. The anchorage obtained with transfixing Kirschner wires fixed in the mandibular distal segment and symphysis is crucial in neonates for the stability of the devices. Moreover, with the use of a second pin for each bone segment, the extraoral devices allow to modify the vector orientation and consequently the shape of the newly formed mandible.

How does the mandible grow after early high condylectomy?

The early high condylectomy (HC), removing the overgrowing area of the condyle, may be indicated for condylar hyperplasia. However, in young patients, when the HC removes the pathological overgrowing tissue the contralateral condyle is still growing. May this surgical procedure, in these growing patients, stop the operated side growth creating the conditions for an opposite asymmetry? Authors investigate the way the operated mandible develops after the early HC, both as a symmetry percentage and in an absolute value related to the unaffected side. A sample of 8 consecutive growing patients, 1 male and 7 females, referred to the Maxillofacial Surgery Department of Parma University for HC were investigated. Patients were longitudinally studied with 3 orthopantomographies at: T0 (diagnosis: mean age, 13 years; range, 11 years 2 months to 13 years 8 months), T1 (after surgery: mean age, 15; range, 13-18 years) and T2 (follow-up: mean age, 18 years; range, 17-20 years). The x-ray is used to study the condyle, ramus, and total vertical structures length by Mattila tracing method. The data were analyzed by the Student t test and Wilcoxon matched pairs test; P value was set at 0.5. The operated side was overcorrected by HC and; during the investigated period, its growth decreased from T0 to T1 and restarted from T1 to T2. The whole T0-T2 growth of the operated side was not statistically different from the one of the healthy side (P < 0.05). These results suggest that the operated side growth may continue in a more normal way after condylectomy.

Ancillary procedures in facial animation surgery.

PURPOSE: Facial animation surgery with neuromuscular transplants has become a standard procedure for the treatment of facial palsies. However, the forehead, periocular complex, nasal base area, and inferior lip are secondary sites that also need to be considered in the complete rehabilitation of a flaccid facial palsy. MATERIALS AND METHODS: A total of 136 ancillary procedures were performed in 49 patients between 2003 and 2013 and consisted of eyebrow suspensions (11), upper eyelid loading with a platinum chain (39), inferior palpebral suspension with fascia lata (22), nasal base suspension with fascia lata (26), and botulinum toxin injection (38). RESULTS: Cosmetic results were good and excellent in 30.7% and 63.2% of the procedures, respectively. Functionally, periocular complex rehabilitation and nasal base suspension led to excellent improvements in function in 87.2% and 73.1% of the patients, respectively. CONCLUSIONS: The use of ancillary procedures can improve the functional and esthetic results of facial animation surgery.

Percutaneous injection of sclerosant agents as an effective treatment for cystic malformations of the head and neck.

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.

Mandibular resection and reconstruction in the management of extensive ameloblastoma.

PURPOSE: To present our experience with the management of 31 extensive mandibular ameloblastomas treated with segmental mandibulectomy, reconstruction with free fibula or iliac crest flap, and rehabilitation with immediate or delayed endosteal dental implants. PATIENTS AND METHODS: The study sample comprised 31 patients with histologically confirmed mandibular ameloblastomas. Primary ameloblastomas were treated in 23 patients, and recurrent ameloblastomas affected 8 patients. Mandibular defect sizes ranged from 3.5 to 12.5 cm (mean, 5.6 cm). A free fibula osseous or osteocutaneous flap was used 17 times for reconstruction; in the remaining 14, a free iliac crest osseous or osteomuscular flap was chosen. Dental implants were positioned in 25 patients; implant procedures were performed simultaneously with reconstruction in 21 cases. RESULTS: All flaps were transplanted successfully, and no major complication occurred postoperatively. Final histologic examinations showed 27 multicystic and 4 unicystic ameloblastomas. Free margins were achieved in all patients. The duration of follow-up was 18 to 120 months (mean, 53.6 months). No patient showed clinical or radiologic signs of recurrence. The dental implant success rate was 100%. CONCLUSIONS: Segmental mandibular resection followed by immediate defect reconstruction with bone-containing free flaps with immediate dental implant placement should be considered as the treatment of choice for extensive mandibular ameloblastomas.

Nebulized hyaluronic acid improves nasal symptoms after orthognathic surgery: a randomized clinical trial.

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.

The free anterolateral thigh musculocutaneous flap for head and neck reconstruction: one surgeon's experience in 92 cases.

BACKGROUND: Applications of the free anterolateral thigh (ALT) musculocutaneous flap have been largely underestimated compared with indications for fasciocutaneous or perforator flaps. In this article, the authors critically review the experience of a single surgeon with the free ALT musculocutaneous flap for head and neck reconstruction, focusing on its applications in different cephalic areas and on advantages and disadvantages of this technique. PATIENTS AND METHODS: Ninety-two patients were treated using a free ALT musculocutaneous flap. Reconstructed areas included tongue, oropharynx, mandible, maxilla, hypopharynx, cheek, and skull base. RESULTS: Flap survival rate was 97.8%. Donor site morbidity consisted in two cases of partial necrosis of the skin graft used its closure with a final donor site complication rate of 2.2%. Overall results showed an 89% of patients returned to a normal or a soft diet. Speech was good or intelligible in 88% and cosmesis resulted good or acceptable in 89% of cases. CONCLUSION: The free ALT musculocutaneous flap offers unique advantages in head and neck reconstructions including adequate bulk when needed, obliteration of dead space, support for the soft tissues of the face, low donor-site morbidity, and harvesting without needing for perforators dissection, allowing for optimal patient outcome. Excessive bulky and thickness of subcutaneous tissue, especially in occidental population, have to be considered as the main disadvantages of this technique, finally the high incidence of hairy skin in thigh area in male patients and donor site scars associated with the use of skin grafts have to be considered as supplementary minor drawbacks.
