Did temporomandibular gap arthroplasty with temporalis interpositional flap improve function and pain in patients with end-stage joint disease? A 5-year retrospective follow-up.

The primary aim of this study was to investigate whether patients with end-stage temporomandibular joint (TMJ) disease treated with gap arthroplasty with temporalis interpositional flap (GAT) had improved maximal interincisal opening (MIO) and TMJ pain in a long-term perspective. All patients with severe osteoarthritis, or fibrous or bony ankyloses, and subjected to GAT between 2008 and 2015 were included. The criteria of treatment success were TMJ pain VAS score ≤4 and MIO ≥30 mm. Reoperation was considered as a failure. Forty-four patients (mean age 47 years) were included in this retrospective descriptive case series and followed up for up to 7 years (mean 4.5). Comorbidities were frequent (n = 34) and most commonly rheumatic disease (n = 17). The indications for surgery were ankylosis (n = 32) or severe osteoarthritis (n = 12). Of the 44 included patients, 84% (n = 37) had a history of earlier TMJ surgery. The preoperative mean values for TMJ pain and MIO (VAS 7 and 23 mm, respectively) changed significantly (p < 0.001) to postoperative means of VAS 3 and 34 mm, respecitvely. The success rate was 59% (n = 26). When compared with a previous 2-year follow-up, the success rate was found to have decreased over time (p = 0.0097). The rate of successful treatment outcome in terms of MIO alone was 82% (n = 36). The most common reason for treatment failure was residual pain. In conclusion, the success-rate after GAT did not show long-term stability and continued to drop over time in this patient cohort. TMJ pain seems to be the main reason for failure.

Effects of Pterional and Osteoplastic Craniotomy on Temporalis Muscle and Calvarial Bone Graft Atrophy.

This study aims to compare the effects of osteoplastic craniotomy on temporalis muscle and bone graft atrophy in patients operated on with a pterional approach to the standard technique. Patients operated on for an intracranial aneurysm with a pterional approach between 2014 and 2018 were studied. Following the exclusion criteria, 36 patients were included in this retrospective study. Temporalis muscle volume and bone graft volume were calculated. The volumes were compared from preoperative and postoperative computed tomography images for temporalis muscle and from early and late postoperative computed tomography images for the bone graft. The osteoplastic craniotomy group (group I) had 17 patients, and the standard craniotomy group had 19 patients (group II). Temporalis muscle volume and bone graft volume decreased statistically significantly in group II after surgery. However, no significant volume difference was found in group I measurements. When compared with the standard technique, osteoplastic craniotomy reduces the likelihood of postoperative temporalis muscle and bone graft atrophy in patients undergoing pterional craniotomy. As a result, the patients' cosmetic and functional well-being is improved.

Quantitative analysis of facial symmetry and animation following intraoral orthodromic temporalis transfer in facial paralysis.

This study aimed to quantitatively analyze the degree and vector of commissure excursion following intraoral orthodromic temporalis transfer. Patients with unilateral facial paralysis who underwent intraoral temporalis transfer were included. Intra-oral coronoidectomy was followed by submucosa tunneling through two vertical intraoral incisions to fixate the temporalis tendon to the perioral location. Oral commissure excursion, upper lip and commissure height differences, and smile angle were measured. Postoperatively, the symmetry of commissure excursion improved in repose (affected side: 114.6 ± 7.0 mm, non-affected side: 115.2 ± 4.9 mm, p = 0.134), while asymmetry arose in smiling (affected side: 30.7 ± 3.4 mm, non-affected side: 34.5 ± 4.4 mm, p = 0.001). Furthermore, the postoperative smile angle demonstrated insufficient vertical movement on the affected side during smiling (affected side: 115.6 ± 5.8°, non-affected side: 118.4 ± 4.9°, p = 0.002) but no significant difference in repose (p = 0.134). Within the limitations of the study it seems that intraoral orthodromic temporalis transfer yields excellent resting symmetry, but smile asymmetry may occur owing to insufficient oral commissure excursion. Nevertheless, as a minimally invasive surgery, this technique can obviate visible scars and benefit patients wishing for the same and can have excellent resting symmetry.

Orbital exenteration reconstruction using a superficial temporalis muscle flap: The "Carpaccio flap", an innovative approach.

INTRODUCTION: Malignant orbital diseases may lead surgeons to practice an orbital exenteration associated with chemotherapy and/or radiotherapy to ensure curative treatment. That radical procedure makes physicians consider reconstructive filling in order to allow prothesis wearing and reduce esthetic and social after-effects. We first describe the clinical case of a 6-year-old patient who presented an orbital rhabdomyosarcoma and underwent an orbital exenteration with immediate reconstruction by a superficial temporal pedicled on the middle temporalis muscle flap. TECHNICAL NOTE: Through that case-report, we propose an original temporal flap to repair ipsilateral midface defects which may reduce donor site side effects and allow furthers corrections. DISCUSSION: In pediatrics cases, our Carpaccio flap was an available regional tool to rehabilitate an irradiated orbital socket with an appropriate bulking and vascularization effect after subtotal exenteration. Furthermore, we prescribe that flap as a posterior orbital filling, when eyelid and conjunctiva are spared, to prepare orbital prosthesis implementation. A mild sunken temporal fossa appears with our procedure but by preserving the deep layer of the temporalis muscle, autologous reconstruction such as lipofilling are permitted in post-radiotherapy condition to enhance esthetic sequelae.

Chronological Volume Changes of the Temporal Muscle Pedicle Used for Encephalo-myo-synangiosis in Combined Revascularization for Moyamoya Disease: A Prospective Observational Study.

Although postoperative neurological events due to brain compression by the swollen temporal muscle are a rare complication, the chronological volume changes of the temporal muscle pedicle and their clinical impact have not yet been documented. This prospective observational study aimed to investigate the chronological volume changes in the temporal muscle pedicle in Moyamoya disease (MMD). Eighteen consecutive combined revascularization procedures using the temporal muscle were performed for symptomatic MMD in 2021. The postoperative pedicle volume was quantified using repeated computed tomography images on postoperative days (PODs) 0, 1, 7, 14, and 30. Postoperative neurological events with radiological evaluations and collateral development evaluated using magnetic resonance angiography obtained 6 months after surgery were studied. On average, the postoperative temporal muscle pedicle volume was most significantly increased by as much as 112% ± 9.6% on POD 7 (P < 0.001) and decreased by as little as 52% ± 21% on POD 30 (P < 0.0001) relative to POD 0. One exceptional patient (overall incidence, 5.6%) demonstrated postoperative transient neurological events due to brain compression by the swollen temporal muscle with decreased focal cerebral blood flow in the adjacent cortical area. The postoperative collateral development via direct and indirect revascularizations was confirmed in 16 (89%) and 12 (67%) hemispheres, respectively. All patients, except for one rebleeding case, showed independent outcomes at the mean latest follow-up period on 290 ± 96 days after surgery. Our observations confirmed the temporal profile of muscle pedicle volume changes after combined revascularization. Through routine attempts to avoid the unfavorable effects of temporal muscle swelling, combined revascularization can provide favorable outcomes in symptomatic MMD.

Salvation of Temporalis Muscle in Cranioplasty: A Technique Note.

OBJECTIVE: The preservation of the temporalis muscle during cranioplasty is very important for postoperative masticatory function and aesthetics. The key technique for temporalis muscle preservation is to find the surgical plane during the operation. METHODS: In the past, the so-called antiadhesion method could not be used to find the surgical plane very well. Here, we describe a novel method for separating the temporalis muscle and dura through an illustrative case, utilizing the natural space of the temporalis muscle at the bony border attachment point. RESULTS: The temporalis muscle is stretched by a wire saw to find the surgical plane quickly and accurately, maximizing the preservation of the temporalis muscle without damaging the dura. CONCLUSIONS: The technical effect is ideal, the operation is simple, and the technique is suitable for promotion.

Reappraisal of the anatomy of the frontotemporal branches of the facial nerve.

OBJECTIVE: The anatomy of the temporal branches of the facial nerve (FN) has been widely described in the neurosurgical literature because of its relevance in anterolateral approaches to the skull base and implication in frontalis palsies from these approaches. In this study, the authors attempted to describe the anatomy of the temporal branches of the FN and identify whether there are any FN branches that cross the interfascial space of the superficial and deep leaflets of the temporalis fascia. METHODS: The surgical anatomy of the temporal branches of the FN was studied bilaterally in 5 embalmed heads (n = 10 extracranial FNs). Exquisite dissections were performed to preserve the relationships of the branches of the FN and their relationship to the surrounding fascia of the temporalis muscle, the interfascial fat pad, the surrounding nerve branches, and their final terminal endpoints near the frontalis and temporalis muscles. The authors correlated their findings intraoperatively with 6 consecutive patients with interfascial dissection in which neuromonitoring was performed to stimulate the FN and associated twigs that were observed to be interfascial in 2 of them. RESULTS: The temporal branches of the FN stay predominantly superficial to the superficial leaflet of the temporal fascia in the loose areolar tissue near the superficial fat pad. As they course over the frontotemporal region, they give off a twig that anastomoses with the zygomaticotemporal branch of the trigeminal nerve, which crosses the superficial layer of the temporalis muscle, spanning the interfascial fat pad, and then pierces the deep temporalis fascial layer. This anatomy was observed in 10 of the 10 FNs dissected. Intraoperatively, stimulation of this interfascial segment yielded no facial muscle response up to 1 mA in any of the patients. CONCLUSIONS: The temporal branch of the FN gives off a twig that anastomoses with the zygomaticotemporal nerve, which crosses the superficial and deep leaflets of the temporal fascia. Interfascial surgical techniques aimed at protecting the frontalis branch of the FN are safe in their efforts to protect against frontalis palsy with no clinical sequelae when executed properly.

Clinical Efficacy of Superficial Temporal Artery-middle Cerebral Artery Bypass Grafting Surgery Combined With Temporal Muscle Patch on Patients With Moyamoya Disease.

OBJECTIVE: To analyze the clinical efficacy of superficial temporal artery-middle cerebral artery (STA-MCA) bypass grafting surgery combined with temporal muscle patch and STA-MCA bypass grafting surgery alone on patients with moyamoya disease. METHODS: Totally 73 patients confirmed with moyamoya disease in our hospital between January 2019 and December 2021 were enrolled. Among them, 43 patients treated with STA-MCA bypass grafting surgery combined with temporal muscle patch were assigned to the experiment group, whereas 30 patients treated with STA-MCA bypass grafting surgery alone to the control group. The following items of the 2 groups were compared: clinical efficacy, total effective rate, and disease control rate 6 months after surgery, the changes of modified Rankin Scale (mRS) and Karnofsky performance scale (KPS) scores before and on the seventh day and 6 months after surgery, and changes of Glasgow coma scale scores before and 24 hours after surgery. In addition, the incidences of cerebral ischemia and cerebral hemorrhage within 1 year after surgery were counted. The cerebral perfusion-associated indexes including relative mean transit time (rMTT), relative time-to-peak, relative cerebral blood flow (rCBF), and relative cerebral blood volume (rCBV) on the seventh day and 6 months after surgery were compared between the 2 groups, and the predictive value of cerebral perfusion-associated indexes before surgery for clinical efficacy on patients was analyzed. RESULTS: The Glasgow coma scale score after surgery ( P >0.05) was similar between the 2 groups, but the clinical efficacy and total effective rate of the 2 groups were notably different (both P <0.05). Compared with those before surgery, mRS scores of both groups declined, whereas KPS scores increased (both P <0.05) on the seventh day after surgery. In addition, compared with those before surgery and on the seventh day after surgery, mRS scores of both groups decreased 6 months after surgery, whereas KPS scores increased (both P <0.05). Both the groups showed decreased rMTT and rTPP, and increased rCBF and rCBV on the seventh day after surgery than those before surgery (all P <0.05). In addition, both the groups still showed decreased rMTT and rTPP, and increased rCBF and rCBV 6 months after surgery than those before surgery and on the seventh day after surgery (all P <0.05). Most notably, the experimental group displayed improved cerebral perfusion-associated indexes than the control group 6 months after surgery (all P <0.05). The relief group showed notably higher rCBF and rCBV levels than the nonrelief group (both P <0.05). According to ROC analysis, the areas under the curves of rCBF and rCBV in forecasting the clinical efficacy on patients were 0.842 and 0.823, respectively. CONCLUSION: Superficial temporal artery-middle cerebral artery bypass grafting surgery combined with temporal muscle patch can deliver a higher total clinical curative rate for patients with moyamoya disease and can alleviate their coma.

An Unusual Case of Severe Trismus After Craniotomy.

Myositis ossificans Traumatica (MOT) is a non-neoplastic, heterotrophic ossifying disease process in muscle and soft tissue rarely involving the craniofacial area. Treatment depends on the extent of ossification and functional limitations. We present the first case of MOT of the temporalis muscle following neurosurgical intervention. This is the case of a 28-year-old male patient who underwent numerous neurosurgical interventions and reported progressive trismus following these interventions. Imaging demonstrated a right temporal region radio-opacity consistent with ossification of the temporalis muscle. The patient underwent coronoidectomy with excision of the ossified right temporalis muscle and reconstruction with an anterolateral thigh adipofascial vascular free flap. Postoperatively, he maintained intact function with increased incisal opening and no cosmetic defects. Limited mouth opening after the neurological procedure has a wide differential, and MOT must be considered. Surgical repair and reconstruction are multifaceted problems. Free flap reconstruction should be considered in multiple operated patients.

Subfascial dissection and extended temporal muscle detachment for middle fossa approach.

BACKGROUND: The soft tissue dissection for the middle fossa approach requires adequate management of the neuro, vascular, and muscular structures in order to maximize exposure and diminish morbidities. METHODS: An incision anterior to the tragus is performed, extending from the zygomatic process to the superior temporal line. The superior temporal artery is exposed, followed by a subfascial dissection of the frontalis nerve. The temporal muscle is dissected and released from the zygoma. All cranial landmarks are exposed for the 5 × 5 cm temporal fossa craniotomy. CONCLUSION: This novel approach provides a safe and adequate access to perform an extended middle fossa craniotomy.

"The Double S" Technique: Subfascial Dissection and Temporalis Muscle Splitting to Prevent Cerebrospinal Fluid Leak and Maximize Surgical Exposure.

BACKGROUND: Middle cranial fossa surgery commonly is approached either performing a subtemporal or a pterional craniotomy. To maximize a basitemporal region exposure, an adjunctive bone drilling could be required. In these cases, a watertight dura and temporalis muscle closure are mandatory. OBJECTIVE: To describe a modified temporalis muscle dissection in middle cranial fossa surgery to increase basitemporal region exposure while assuring a safe and effective closure thus avoiding cerebrospinal fluid (CSF) leakage. METHODS: A total of 8 patients have been enrolled. Five pterional and 3 subtemporal approaches were performed. In all cases, the novel subfascial muscle dissection and temporalis muscle splitting technique named "the double S technique," was performed to cut up the temporal muscle. RESULTS: In all cases, a subgaleal drainage was used and removed within 48 hours. No cases of postoperative CSF leak or hematoma collection were reported. CONCLUSIONS: The double S technique is a safe and effective alternative to enhance the basitemporal region exposure while avoiding the potential, common risk of CSF leak.

Antegrade Subperiosteal Temporalis Muscle Elevation and Posterior Retraction Technique Avoiding Muscle Incision for Pterional Craniotomy: A Technical Note.

Background: The current technique of pterional craniotomy involves temporalis muscle incision followed by retrograde elevation. Feasibility of antegrade temporalis muscle elevation without any direct incision over its bulk is evaluated. Objective: Incisionless "antegrade, subgaleal, subfascial, and subperiosteal elevation" of temporalis muscle preserves vascularity and muscle bulk. Posterior maneuvering of "bare" temporalis muscle bulk either above (out rolling) or under (in rolling) the scalp for pterional craniotomy is discussed. Material and Methods: Technique of antegrade, subfascial, subperiosteal elevation, and posterior rotation of temporalis muscle without incising in its bulk by "out rolling" or "in rolling" along the posterior aspect of the scalp incision was carried out in 15 cadavers and later in 50 surgical cases undergoing pterional craniotomy. Postoperatively, patients were evaluated for subgaleal collection and periorbital edema. Operated side cosmesis and temporalis muscle bulk was compared with nonoperated temporalis muscle at 6 months interval. Results: Antegrade subperiosteal dissection of temporalis muscle was possible in all cases. "In-rolling" or "out rolling" technique provided adequate surgical exposure during pterional craniotomy. Postoperative subgaleal collection and periorbital edema was prevented. Facial nerve paresis or temporalis muscle-related complications were avoided. Conclusion: Antegrade, subgaleal, subfascial, and subperiosteal dissection techniques of temporalis muscle elevation without any direct incision in its bulk enables neurovascular and muscle volume preservation. Posterior maneuvering of elevated temporalis muscle with "out rolling" or "in-rolling" technique is easy, quick, and provides adequate exposure during pterional craniotomy. Opening and closing of scalp layers without violating subgaleal space prevent postoperative subgaleal hematoma and periorbital edema.

Public and patients' perceptions of facial reanimation using lengthening temporalis myoplasty.

OBJECTIVES: To answer the clinical research questions: "Among facial paralysis patients (FPPs), did lengthening temporalis myoplasty (LTM) improve public's perceptions, patients' perceptions, as well as objective oral measurements of post-operative outcomes?" METHODS: To answer the research questions, we designed and implemented a hybrid cross-sectional and retrospective cohort study enrolling a cohort of laypersons and FPPs treated at a tertiary care center from 2011 to 2020. The primary predictor variables were LTM in FPPs (before/after) and medical background on medical care (FPPs/laypersons). The main outcome variable was post-operative outcomes (from a public's perspective, FPPs' perspective, and with objective measurements). Descriptive and univariate statistics were computed as appropriate, and P ≤ 0.05 was considered statistically significant. RESULTS: The sample consisted of 203 lay volunteers and 15 FPPs. After LTM, public perception voted the significant improvements in disfigured, important to repair, bothersome, severity (DIBS) score, and facial attractiveness. Patients' perspective was also significantly improved for global severity, oral function, and facial movement. Objective measurements of deviation at the oral commissure and the smile angle also significantly improved after LTM. CONCLUSION: Despite no control groups (i.e., other techniques to be compared) in this study, our study results suggest that LTM can be used to improve public's perception, patient's perception, and objective oral measurement of post-operative outcomes in FPPs. Because different questionnaires were used, it is unknown whether public and patient's perceptions are compatible.

Anchoring the Temporalis Muscle with an Intact Fascial Layer Along the Superior Temporal Line in Pterional Craniotomy: A Technical Note.

BACKGROUND: Manipulation of the temporalis muscle during pterional and frontotemporal approaches poses major cosmetic and functional issues postoperatively. The temporalis muscle has usually been secured in its normal position using implants or by leaving a thin rim of muscle and fascia attached along the superior temporal line. In the present report, we have described a pure tissue-based method of anchoring the intact temporalis muscle precisely along the superior temporal line. METHODS: A total of 30 consecutive cases of pterional or frontotemporal craniotomy were performed by single surgeon (SKR). A subfascial dissection technique was used to expose the transition zone of the frontal pericranium with the temporalis fascia. These were then separated by sharp dissection along the superior temporal line at which the muscle is attached. The temporalis muscle and fascia were repositioned during closure, precisely at their original anatomical location by passing multiple anchoring sutures along the free edge of the muscle and fascia lying along the superior temporal line. RESULTS: Temporalis muscle reattachment was achieved in all 30 cases with good cosmesis and functional outcome without temporalis muscle-related complications at 6 months of follow-up. CONCLUSIONS: The approximation of sutures running through the free edge of the temporalis muscle with intact fascia along the superior temporal line from anteriorly to posteriorly restored the muscle and fascial layer to its original position. Avoidance of the formation of any potential dead space during surgical exposure will prevent periorbital edema and/or subgaleal collection postoperatively. The described inexpensive technique avoids implant-related complications, with good functional and aesthetic outcomes. A comparative study is needed to establish the superiority of this procedure over other techniques.

Modified Lengthening Temporalis Myoplasty Using an Intraoral Approach.

BACKGROUND: Lengthening temporalis myoplasty (LTM) is a unique and definite facial reanimation procedure that involves inserting the whole temporal tendon directly into the nasolabial fold. However, the nasolabial fold incision remains one of the difficulties of this procedure, particularly in young or female patient. To avoid the need for this incision, the authors developed an intraoral approach to manipulate the temporal muscle tendon toward the nasolabial fold. in this study, we describe the details of this procedure. METHOD: The authors performed their intraoral approach procedure in 5 patients with established complete facial paralysis. instead of making an incision at the nasolabial fold to approach the coronoid process, the authors made the incision at the buccal mucosa. The results were evaluated both subjectively and objectively. RESULTS: The authors achieved facial reanimation without leaving any obvious scar on the face or neck and the effect of static reconstruction is obvious, even immediately after the surgery. All the patients obtained good facial movement within 4 months (2.5 months in average), and improved all evaluated parameters postoperatively. No infections or other major complications were reported following surgery; however, 1 patient developed a slight dimple that required revision. DISCUSSION: The authors could advance temporal tendon toward nasolabial fold firmly obtaining sufficient surgical field similar to that of nasolabial fold incision, and achieved fairly good results without an obvious scar on the face.Establishing LTM without nasolabial fold incision, we could expand the indication of LTM more widely, and it could be more familiar procedure for smile reanimation in all generation.

El colgajo de músculo temporal en la cirugía de la ATM: ¿sigue siendo una opción válida? / The temporalis muscle flap in TMJ surgery: is it still a valid option?

El músculo temporal ha sido utilizado en reconstrucción craneofacial durante más de 130 años. En la cirugía de ATM se ha utilizado en dos entidades fundamentalmente: la anquilosis de la ATM y como reemplazo del disco articular postdiscectomía. El objetivo de esta revisión es valorar si el colgajo de músculo temporal sigue teniendo indicación en la cirugía de ATM o si hay alternativas más apropiadas para estas entidades. Para ello, se realiza una revisión narrativa sobre el uso del colgajo del músculo temporal en la cirugía de la ATM en base a los artículos que hicieran referencia a su utilización de forma individual o comparando con otras técnicas. Realizamos una descripción de la técnica quirúrgica y sus principales cambios a través de los años. En la cirugía de la anquilosis, el tratamiento busca eliminar la parte anquilótica, restablecer la función articular y sobre todo prevenir la reanquilosis. La utilización del músculo temporal, como material de interposición, ha demostrado disminuir la incidencia de reanquilosis, pero sus complicaciones han llevado a buscar alternativas. En cirugía de los trastornos internos de la ATM, su uso como reemplazo del disco comenzó en los años 90, pero ante la controversia actual de si es necesario o no reemplazar el disco al realizar discectomía, las posibles ventajas teóricas de este colgajo no compensan sus complicaciones. En conclusión, esta técnica, en la cirugía de la ATM, tiene alternativas con mejores resultados, lo que hace que ya no sea de primera elección. (AU)

The temporalis muscle has been used in craniofacial reconstruction for more than 130 years. In TMJ surgery, it has been used fundamentally in two entities: TMJ ankylosis and as a post-discectomy joint disc replacement. The objective of this review is to assess whether the temporalis muscle flap continues to have an indication in TMJ surgery, or whether there are more appropriate alternatives for these entities. To do this, a narrative review is carried out on the use of the temporalis muscle flap in TMJ surgery based on the articles that refer to its use individually or in comparison with other techniques. We make a description of the surgical technique and its main changes over the years. In ankylosis surgery, the treatment seeks to eliminate the ankylotic part, restore joint function and, above all, prevent re-ankylosis. The use of the temporalis muscle, as an interposition material, has been shown to reduce the incidence of re-ankylosis, but its complications have led to the search for alternatives. In surgery for internal derangement, its use as a disc replacement began in the 1990s but given the current controversy as to whether it is necessary to replace the disc when performing a discectomy, the possible theoretical advantages of this flap don't compensate its complications. In conclusion, this technique, in TMJ surgery, has alternatives with better results, which means that it is no longer the first choice. (AU)

Defecto oncológico maxilar reconstruido mediante colgajo de músculo temporal / Maxillary oncologic defect reconstructed with temporal muscle flap / Defeito oncológico maxilar reconstruído por aba muscular temporal

El macizo facial es una región anatómica compleja que alberga órganos sensoriales. El desarrollo de una enfermedad oncológica, así como su tratamiento, causan defectos funcionales y estéticos con un alto costo físico y psíquico para el paciente y su entorno. Es por ello que la reconstrucción representa un reto. Las diferentes posibilidades incluyen prótesis obturatríces, colgajos libres, pediculados o microvascularizados. En este artículo se describirá el colgajo de músculo temporal y se desarrolla un caso clínico de cirugía oncológica maxilar reconstruido mediante éste en un paciente que presenta una lesión exofítica en cuadrante superior derecho, que se extiende sobre el flanco vestibular, reborde alveolar y zona palatina, desde zona de premolares hasta la zona del segundo molar inclusive, impidiéndole usar la prótesis dental. Esta cirugía es una técnica económica, que requiere menor tiempo quirúrgico que otras técnicas, asociándose a poco porcentaje de fracaso y pocas complicaciones post operatorias.

The facial mass is a complex anatomical region that houses sensory organs. The development of an oncologic disease, as well as its treatment, causes functional and esthetic defects with a high physical and psychological cost for the patient and his environment. This is why reconstruction represents a challenge. The different possibilities include obturator-root prostheses, free, pedicled or microvascularized flaps. In this article the temporal muscle flap will be described and a clinical case of maxillary oncologic surgery reconstructed by means of it is developed in a patient who presents an exophytic lesion in the right upper quadrant, which extends over the vestibular flank, alveolar ridge and palatal area, from the premolar area up to and including the second molar area, preventing him from using the dental prosthesis. This surgery is an economical technique that requires less surgical time than other techniques, and is ass

A massa facial é uma região anatômica complexa que abriga órgãos sensoriais. O desenvolvimento de uma doença oncológica, assim como seu tratamento, causa defeitos funcionais e estéticos com alto custo físico e psicológico para o paciente e seu ambiente. A reconstrução é, portanto, um desafio. As diferentes possibilidades incluem as próteses de raiz obturadora, abas livres, pediculadas ou microvascularizadas. Este artigo descreve o retalho muscular temporal e descreve um caso clínico de cirurgia oncológica maxilar reconstruída utilizando-o em um paciente com lesão exofítica no quadrante superior direito, estendendo-se pelo flanco vestibular, rebordo alveolar e área palatina, desde a área do pré-molar até a área do segundo molar inclusive, impedindo-o de utilizar a prótese dentária. Esta cirurgia é uma técnica econômica, que requer menos tempo cirúrgico que outras.

Minimally invasive temporalis tendon transposition and upper lid lipofilling for immediate and secondary facial reanimation in patients treated for malignant tumors of the parotid gland.

Treatment for facial nerve-invading parotid malignancies usually results in complete facial palsy. The authors present a novel technique to treat facial palsy following radical parotid surgery and retrospectively evaluate results in terms of soft tissue symmetry at rest and during smiling and eyelid closure using the eFACE system. 9 patients with facial palsy following parotid malignancies resection or undergoing parotidectomy with planned facial nerve resection for tumor invasion were treated with the association of mini-invasive temporalis flap rotation and upper lid lipofilling to restore symmetry of the middle facial third at rest and during smiling and eyelid closure. The technique was employed during the same surgical session as the tumor removal or for secondary facial reanimation. Systematic eFACE evaluation demonstrated significant improvement in static nasolabial fold depth orientation and oral commissure position, palpebral fissure narrowing during eye closure, and oral commissure movement and nasolabial fold depth and orientation with smile (p respectively .008, .011, 0.008, 0.035, 0.011, 0.008, and 0.011, Wilcoxon's test). Furthermore, all patients described subjective improvement of corneal discomfort. The presented technique appears promising in treating facial palsy in oncological patients, representing a potential alternative to other more complex reconstructive techniques.
