RESUMO

Objective: To evaluate the therapeutic effect of a novel air-cooled Nd:YAG laser in the venous lakes of the lips (VLL). Background: The thermal injury is one of the most important issues during laser therapy for venous lakes. Methods: Six pieces of fresh pork livers were used to provide 30 regions with a diameter of 6 mm for experiment in vitro, among which 15 regions were treated by Nd:YAG laser with air cooling until the tissue turned gray-white, whereas the rest were treated without air cooling as control. The operation time of laser irradiation, the degree of temperature increase, and the depth of coagulation tissue were compared between two groups. Then, 60 VLL patients were selected for Nd:YAG laser treatment with or without air cooling. The operation time of laser irradiation, the degree of temperature increase, the postoperative pain visual analog scale (VAS) score, and the percentage of lesions removed within 1 month were compared. Results: In tissue studies, the treated group showed a longer operation time of laser irradiation (p < 0.01), a lower degree of temperature increase (p < 0.01), and there was no significant statistical difference in the depth of coagulation tissue (p = 0.624). In clinical studies, the treated group showed a longer operation time of laser irradiation (p < 0.01), a lower degree of temperature increase (p < 0.01), and a lower VAS score on the 1st and 2nd day, compared with the control group (p < 0.01). Conclusions: Air cooling during Nd:YAG laser for the treatment of VLL can prolong the surgical time, but lowered tissue temperature and reduced patient pain within 2 days under the premise of ensuring the treatment effect.

RESUMO

BACKGROUND: Balance is achieved through opposing interactions. Objective three-dimensional assessment of changes during surgical treatment of the unilateral cleft lip and nasal deformity are limited, and false assumptions may prevent optimal management. METHODS: The authors performed anthropometric analysis on the immediate preoperative and postoperative images (captured under anesthetic) of patients undergoing primary repair ( n = 36). Changes in dimensions and measures of balance were assessed ( P < 0.05). RESULTS: Angles and ratios that reflect cleft to noncleft side balance normalized, although alterations occurred in opposing ways. Centralization of the columella narrowed the cleft nasal base and widened the noncleft nasal base. As the cleft columellar height elongated, the noncleft columellar height shortened. With these changes and correction of cleft alar base retrusion, the cleft alar dome was raised. The cleft and noncleft lateral lip heights and widths elongated. Meanwhile, the Cupid's bow broadened as the commissures were drawn closer together. Whereas the cleft philtral height lengthened, the noncleft philtral height shortened. Reduction in noncleft philtral height averaged 20% but varied with measures of preoperative severity including columellar angle ( R = 0.67), the difference in philtral heights ( R = 0.65), and lateral deviation of the subnasale ( R = 0.74). CONCLUSIONS: Tissue does not need to be added to "lengthen" the columella, the noncleft philtral height shortening can be estimated, and the contours of anatomic subunits change with surgery on both cleft and noncleft sides. It is inadequate to focus on correction of the cleft side alone without considering corresponding noncleft side changes. Achieving balance through opposing alterations should be the principal goal of treatment. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

RESUMO

Pollen-food allergy syndrome (PFAS) is an immunoglobulin E (IgE)-mediated allergic reaction caused when patients with pollen allergy ingest food having cross-reactivity with pollen. To date, no effective treatment method for this has been established. Here we report the case of a patient with PFAS who experienced lip edema, causing difficulties in treatment. This report describes the case of a 12-year-old boy with perennial allergic rhinitis since the age of 8 years. After ingesting fresh fruits and raw vegetables at the age of 11 years, he started to experience lip edema repeatedly. Thus, the patient was referred to our department. Based on the results of serum antigen-specific IgE, prick-to-prick, and allergen component tests, he was diagnosed with PFAS. He has been instructed to avoid causative food. Furthermore, the treatment using an antihistamine and antileukotriene receptor antagonist was initiated for pollen allergy. Sublingual immunotherapy (SLIT) for Japanese cedar pollen was initiated because the patient experienced severe nasal allergy symptoms during the dispersal season of this pollen. These treatments alleviated the nasal symptoms; however, the lip edema persisted. Omalizumab administration improved the lip edema. The combination of SLIT and omalizumab may be an effective treatment option for patients with PFAS.

RESUMO

Schwannoma is an uncommon benign tumor in the oral and maxillofacial region, and development of schwannoma in the lower lip is rare. Herein, we present the case of a 68-year-old woman who visited Nihon University Itabashi Hospital complaining of a painless mass in the lower lip. The lesion was surgically resected under local anesthesia. On histopathological examination, the resected specimen was a mixture of Antoni types A and B schwannoma. No recurrence has been seen over a postoperative follow-up period of 58 months. In the schwannoma of the lower lip, the mean tumor volume was compared for type A and the mixed type, which tended to be larger in the mixed type. No previous reports have described the relationship between the size of schwannoma in the lower lip and Antoni classification. Therefore, this report discusses the possibility of a relationship between tumor size and Antoni classification for schwannomas in the lower lip.

RESUMO

BACKGROUND: Various preformed early orthodontic appliances for correcting oral habits and training orofacial muscles have emerged on the market. However, there are few reports on the effectiveness of these appliances for orofacial myofunctional training. METHODS: This retrospective study evaluated children with lip incompetence and mixed dentition treated at the Pediatric Dentistry Department of Shanghai Ninth People's Hospital from 2016 to 2018. A total of 109 children (54 males, 55 females; age range: 7-10 years, mean age: 8.2 years) were selected from an overall sample of 870 patients. During the first visit, all patients were instructed to perform active lip and tongue training at home daily and were divided into two groups according to the kind of appliances worn. The first group consisted of 56 subjects (30 females; 26 males), with a mean age of 8.1 years (SD 1.1 years), treated with preformed appliances. The second group consisted of 53 subjects (25 females; 28 males), with a mean age of 8.2 years (SD 1.0 years), treated with conventional early orthodontic appliances (arch expansion devices along with "2*4" local fixed appliances). For each subject in the two groups, initial (pretreatment, T1) and final (posttreatment, T2) intraoral and external photos, dental casts, lateral cephalograms, and orthopantograms were taken, and lip strength was measured. SNA, SNB, ANB, APDI, FMA, U1SN, and IMPA before and after treatment were measured by The Dolphin Imaging Cephalometric Analysis Software. The hyoid bone position was also recorded. Differences between groups were identified with an independent sample t-test (P < 0.05). RESULTS: In the first group, a statistically significant forward movement of the mandible was detected by an increase in SNB of - 1.06 degrees (P < 0.01) and an increase in APDI of - 2.23 degrees (P < 0.01). The increase in IMPA (- 3.21 degrees, P < 0.01) demonstrated a statistically significant protrusion of the lower incisors. Lip strength significantly increased (- 2.44, P < 0.01). The increase in HC3 (- 1 mm, P < 0.01) and HFH (- 2.95 mm, P < 0.01) implied a forward and downward movement of the hyoid bone. In the second group, a statistically significant forward movement of the mandible was also detected by an increase in APDI of -1.96 degrees (P < 0.01). Lip strength also significantly increased (- 1.24, P < 0.01). The increase in HFH (- 2.55 mm, P < 0.01) implied a downward movement of the hyoid bone. Compared with the treatment in the second group, orofacial myofunctional therapy combined with the preformed appliances led to a statistically significant lip strength increase (- 2.30, P < 0.05). Significant differences were observed in SNB and IMPA between the two groups (P < 0.05). CONCLUSIONS: Orofacial myofunctional therapy effectively improved patient lip strength and was a good option for mixed dentition patients with lip incompetence. Preformed appliances could enhance the orofacial myofunctional therapy effect and result in significant improvements in lip strength and forward movement of the mandible, which can optimize the jaw relationship.

RESUMO

BACKGROUND: Fusarium species are saprophytic fungi with a worldwide distribution. These fungi cause various infections among immunocompromised patients; however, they can also involve immunocompetent individuals. CASE PRESENTATION: We report a case of a 41-year-old Iranian woman who presented with ulcerative lesions on her lips 10 months ago. She had a long history of anxiety but had no history of classical risk factors such as trauma, cosmetic lip tattoo, burning in her lips, smoking or use of alcohol and opium. A skin biopsy from the lower lip was performed and sent for microbiological examinations. Hyaline septate hyphae were seen on direct microscopy with potassium hydroxide. The clinical specimen was subcultured on sabouraud dextrose agar with chloramphenicol and prepared for antifungal susceptibility testing and molecular identification. Considering the minimum inhibitory concentrations (MIC) for antifungals, itraconazole (100 mg orally twice a day) was started for her, and after 2 months, the lesions were treated. She followed up for 3 months, and no signs of disease recurrence were observed. CONCLUSIONS: Selecting an appropriate treatment strategy according to the laboratory assessments is essential in clinical practice and the management of rare infections to prevent related mortality and morbidity of opportunistic fungal infections.

RESUMO

Viewing speaker's lip movements facilitates speech perception, especially under adverse listening conditions, but the neural mechanisms of this perceptual benefit at the phonemic and feature levels remain unclear. This fMRI study addressed this question by quantifying regional multivariate representation and network organization underlying audiovisual speech-in-noise perception. Behaviorally, valid lip movements improved recognition of place of articulation to aid phoneme identification. Meanwhile, lip movements enhanced neural representations of phonemes in left auditory dorsal stream regions, including frontal speech motor areas and supramarginal gyrus (SMG). Moreover, neural representations of place of articulation and voicing features were promoted differentially by lip movements in these regions, with voicing enhanced in Broca's area while place of articulation better encoded in left ventral premotor cortex and SMG. Next, dynamic causal modeling (DCM) analysis showed that such local changes were accompanied by strengthened effective connectivity along the dorsal stream. Moreover, the neurite orientation dispersion of the left arcuate fasciculus, the bearing skeleton of auditory dorsal stream, predicted the visual enhancements of neural representations and effective connectivity. Our findings provide novel insight to speech science that lip movements promote both local phonemic and feature encoding and network connectivity in the dorsal pathway and the functional enhancement is mediated by the microstructural architecture of the circuit.

RESUMO

INTRODUCTION: Cheilitis is the most common mucocutaneous side effect of isotretinoin (ISO). Dexpanthenol (DXP) increases fibroblast proliferation and re-epithelialization in wound healing. We aimed to investigate the effect of DXP-mesotherapy in ISO-induced cheilitis in this study. METHODS: This study was conducted on patients who had been using ISO (0.5-1 mg/kg/day) for at least 2 months. Twenty-five patients who administered DXP-mesotherapy (mesotherapy group) and 33 patients without the procedure (control group, only ointment) participated in this study. All patients were prescribed only hamamelis virginiana distillate in ointment form as a lip balm. The efficacy of the treatment was interpreted by the change in lip balm use frequency, quality of life, and Isotretinoin Cheilitis Grading Scale (ICGS). RESULTS: There was a statistically significant decrease in all ICGS-subgroups scores in the mesotherapy group after 1 month compared with the baseline (p = <0.001), although in the controls, erythema, crust, and fissure scores significantly increased (p = 0.001, p = 0.002).While there was no difference between the groups in terms of ICGS total scores at baseline, there was a significant difference after 1 month in favor of the mesotherapy group (p < 0.001). In the mesotherapy group, lip balms were needed significantly less frequently and there was a significant improvement in quality of life compared with both the control group and at baseline after 1 month (both; p < 0.001). On the other hand, the control patients suffered more from cheilitis and dryness than at baseline (p < 0.001). CONCLUSION: Dexpanthenol-mesotherapy seems to be a safe, and so effective method in management of ISO-related cheilitis.

RESUMO

PURPOSE: To verify the immediate effects of different doses of photobiomodulation on maximum lip pressure. METHODS: Experimental, randomized and triple-blind study. The sample consisted of 23 women and 17 men, age between 18 and 33 years old (average 23.18 years old, SD=2.1), distributed in four groups: CG (control group), G1, G4 and G7. The maximum pressure was assessed with the Iowa Oral Performance Instrument (IOPI). The bulb was placed between the lips and the participants were instructed to press it as strong as possible. Infrared LASER (808 nm), manufactured by DMC, Therapy EC model, 100 mW of power output, was applied. The doses tested were 1 J (G1), 4 J (G4) and 7 J (G7), applied at six points of the orbicularis oris muscle. In the CG there was no intervention. The evaluation procedures were repeated after the LASER application. The results were analyzed with a significance level of 95%. RESULTS: The maximum lip pressure increased significantly only in the group irradiated with 7 J. CONCLUSION: Low level LASER therapy with 7 J dose promoted changes in the performance of the orbicularis oris muscle in the maximum pressure task.

RESUMO

BACKGROUND: Physiological lip hyperpigmentation (PLH) is a common cosmetic concern in the Middle East and Asia. It is characterized by homogeneous symmetric diffuse hyperpigmentation affecting both lips. There is no satisfactory treatment for this condition. The aim of this study is to evaluate the efficacy and safety of Q-switched (QS) 532 nm Nd:YAG laser for PLH. METHODS: A total of 30 patients with clinical diagnosis of PLH were retrospectively reviewed and included in the study. Patients underwent at least one laser treatment using QS 532 nm with a minimum follow up of six months. Laser parameters were as follows: spot size 2-3 mm, pulse duration 20 ns, fluence 2-4 J/cm2. One to three sessions were performed depending on clinical response. Two methods were used for assessment: patient satisfaction and independent physician assessment. PLH was classified as grade 1 (upper lip fully affected plus only border of lower lip), grade 2 (upper lip fully affected plus most of lower lip), and grade 3 (majority of both lips hyperpigmented). RESULTS: Excellent (>75% improvement) response was achieved in 30% of patients. Good (51-75% improvement) response was seen in 37% and 43% of patients according to patient satisfaction and independent physician assessment, respectively. Majority of patients required only one treatment session. Reactivation of herpes labialis occurred in two patients, and mottled hypopigmentation in three patients. None of the patients developed persistent hyperpigmentation or scarring. CONCLUSIONS: PLH can be effectively treated with QS 532 nm Nd:YAG laser and is well tolerated by patients.

RESUMO

Las queilitis por contacto son procesos patológicos de etiología multifactorial de origen externo que generan lesiones en el bermellón de los labios, en algunos casos se acompaña por una dermatitis contigua. Este tipo de queilitis recibe esta denominación debido al mecanismo de acción de la noxa productora, la cual actúa por contacto en la superficie labial produciendo una reacción antígeno anticuerpo. Los agentes sensibilizantes y desencadenantes del proceso inflamatorio son de origen físico y químico en sus diversas formas. Los físicos son los rayos actínicos y ultravioletas. Los químicos son más numerosos, como los cosméticos, alimentos, pastas y cepillos dentales. La incidencia es alta en el sexo femenino y en el labio inferior por su mayor superficie. El objetivo de este estudio fue realizar una evaluación comparativa de la crema de propóleos en el tratamiento de las queilitis por contacto y de la posible reacción adversa medicamentosa. Se llevó a cabo en pacientes de ambos sexos, a partir de los 15 años con diagnóstico clínico de queilitis por contacto, los que fueron asignados en forma aleatorizada simple en dos grupos. El primer grupo de control, recibió tratamiento tradicional. El segundo grupo experimental recibió la formulación objeto de estudio, la crema de propóleos. Ambas medicaciones redujeron de manera significativa la intensidad de la sintomatología y los signos sin efectos adversos en pacientes con queilitis por contacto. La formulación magistral de crema de propóleos objeto del presente estudio, ha demostrado ser efectiva en el tratamiento de las queilitis por contacto.

RESUMO

PURPOSE: To compare the immediate effects of laser photobiomodulation at wavelengths of 660 nm and 808 nm on fatigue of the orbicularis oris. METHODS: This is a randomized study with 60 women aged between 19 and 43 years. The participants were divided into four groups. Group RG received photobiomodulation with a laser wavelength of 660 nm at four points of the orbicularis oris; group IRG received photobiomodulation with a laser wavelength of 808 nm at the same points; the control group did not receive light treatment; and the placebo group underwent the same procedures as RG and IRG but with the equipment switched off. The irradiation was performed with a laser of 100 mW of power, 4 J of energy per point and 133.3 J/cm2 of fluency. An electromyography evaluation was performed before and after the irradiation, concomitantly with the exercise of lip protrusion maintained until the sensation of fatigue. Fatigue was evaluated by a median frequency using the electromyographic fatigue index. The amplitude of the signal was evaluated, examining the root mean square, and the values were normalized by the peak. The difference in amplitude between the upper and lower lips was also analyzed. All variables were compared before and after irradiation. RESULTS: No significant difference was found between the measures taken before and after irradiation. CONCLUSION: Photobiomodulation with the parameters investigated in this study had no immediate effect on orbicular oris fatigue.


OBJETIVO: comparar os efeitos imediatos da fotobiomodulação com laser nos comprimentos de onda 660 nm e 808 nm na fadiga do músculo orbicular da boca. MÉTODOS: trata-se de um estudo experimental randomizado, com 60 mulheres, com idade entre 19 e 43 anos. As participantes foram divididas em quatro grupos. O grupo GV recebeu irradiação com laser de comprimento de onda de 660 nm em quatro pontos do orbicular da boca; o grupo GIV recebeu irradiação com laser de comprimento de onda de 808 nm nos mesmos pontos; o grupo controle não recebeu irradiação e o grupo placebo passou pelos mesmos procedimentos dos grupos GV e GIV, porém o equipamento não foi acionado. A irradiação foi realizada com laser de 100 mW de potência, 4 J de energia por ponto e 133,3 J/cm2 de fluência. Avaliação eletromiográfica foi realizada antes e após a irradiação, concomitantemente ao exercício de protrusão labial sustentada até a sensação de fadiga. O índice de fadiga eletromiográfica foi calculado a partir da frequência mediana. A amplitude do sinal foi avaliada, examinando o RMS, e os valores normalizados pelo pico. A diferença na amplitude entre lábios superiores e inferiores também foi analisada. Todas as variáveis foram comparadas antes e após a irradiação. RESULTADOS: não foram encontradas diferenças significativas nas medidas antes e após a irradiação. CONCLUSÃO: a fotobiomodulação, com os parâmetros investigados neste estudo, não resultou em efeitos imediatos sobre a fadiga do músculo orbicular da boca.

RESUMO

The case report aims to describe the parameters of performing upper labial frenectomy with the use of diode laser beams without infiltrated local anaesthesia. A 6-year-old patient was referred by the orthodontist for assessment of the upper anterior labial frenum. The dental treatment plan reported only the presence of caries on deciduous teeth and seals on the first permanent molars. The clinical examination reported the presence of a high attachments of labial frenum with a pathologically attachment and the presence of a diastema supports this theory. The laser used to remove the frenulum was a diode laser used with a wavelength of 980 nm with 320 microns of fiber in contact with a power of 2.0 W in continuous wave mode. The clinical examination showed an acceptable healing by secondary intention of the wound and the initial functional recovery of a physiological upper lip movements. The patient reported that the procedure was well tolerated. The diode laser can be used with good result for the removal of pathological frenum. The diode laser can be used in pediatric dentistry because of its application, adequate coagulation, no need for sutures and less inflammation and pain.

RESUMO

In natural conversations, visible mouth and lip movements play an important role in speech comprehension. There is evidence that visual speech information improves speech comprehension, especially for older adults and under difficult listening conditions. However, the neurocognitive basis is still poorly understood. The present EEG experiment investigated the benefits of audiovisual speech in a dynamic cocktail-party scenario with 22 (aged 20-34 years) younger and 20 (aged 55-74 years) older participants. We presented three simultaneously talking faces with a varying amount of visual speech input (still faces, visually unspecific and audiovisually congruent). In a two-alternative forced-choice task, participants had to discriminate target words ("yes" or "no") among two distractors (one-digit number words). In half of the experimental blocks, the target was always presented from a central position, in the other half, occasional switches to a lateral position could occur. We investigated behavioral and electrophysiological modulations due to age, location switches and the content of visual information, analyzing response times and accuracy as well as the P1, N1, P2, N2 event-related potentials (ERPs) and the contingent negative variation (CNV) in the EEG. We found that audiovisually congruent speech information improved performance and modulated ERP amplitudes in both age groups, suggesting enhanced preparation and integration of the subsequent auditory input. In the older group, larger amplitude measures were found in early phases of processing (P1-N1). Here, amplitude measures were reduced in response to audiovisually congruent stimuli. In later processing phases (P2-N2) we found decreased amplitude measures in the older group, while an amplitude reduction for audiovisually congruent compared to visually unspecific stimuli was still observable. However, these benefits were only observed as long as no location switches occurred, leading to enhanced amplitude measures in later processing phases (P2-N2). To conclude, meaningful visual information in a multi-talker setting, when presented from the expected location, is shown to be beneficial for both younger and older adults.

RESUMO

Many oral signs and symptoms related to the novel coronavirus disease (COVID-19) have been reported; however, both prevalence and etiology are still undetermined. Since the clinical features of the oral lesions seen in COVID-19 are highly heterogeneous and the treatments differ considerably in the literature, the present study aimed to report a clinical case in which a combination of antimicrobial photodynamic therapy (aPDT) and photobiomodulation therapy (PBMT) was used for extensive lip lesions in a patient suffering from COVID-19. Within 4 days and without any systemic drug administration, after two sessions of aPDT and one session of PBMT, the lip lesions were completely healed, and the patient recovered her orofacial functions satisfactorily. According to the current case report and taking into consideration the evident lack of information about many aspects of COVID-19 infection, this combination of phototherapy modalities seems to be a promising tool for managing COVID-19-related lip lesions; however, more studies are necessary.

Long-term hearing loss in postlingually deaf (PD) adults may lead to brain structural changes that affect the outcomes of cochlear implantation. We studied 94 PD patients who underwent cochlear implantation and 37 patients who were MRI-scanned within 2 weeks after the onset of sudden hearing loss and expected with minimal brain structural changes in relation to deafness. Compared with those with sudden hearing loss, we found lower gray matter (GM) probabilities in bilateral thalami, superior, middle, inferior temporal cortices as well as the central cortical regions corresponding to the movement and sensation of the lips, tongue, and larynx in the PD group. Among these brain areas, the GM in the middle temporal cortex showed negative correlation with disease duration, whereas the other areas displayed positive correlations. Left superior, middle temporal cortical, and bilateral thalamic GMs were the most accurate predictors of post-cochlear implantation word recognition scores (mean absolute error [MAE] = 10.1, r = .82), which was superior to clinical variables used (MAE: 12.1, p < .05). Using the combined brain morphological and clinical features, we achieved the best prediction of the outcome (MAE: 8.51, r = .90). Our findings suggest that the cross-modal plasticity allowing the superior temporal cortex and thalamus to process other modal sensory inputs reverses the initially lower volume when deafness becomes persistent. The middle temporal cortex processing higher-level language comprehension shows persistent negative correlations with disease duration, suggesting this area's association with degraded speech comprehensions due to long-term deafness. Morphological features combined with clinical variables might play a key role in predicting outcomes of cochlear implantation.

RESUMO

BACKGROUND AND OBJECTIVES: Laser is being widely used in clinical treatment nowadays, including 755 nm Alexandrite laser [1,2]. This study was conducted to examine the clinical outcome of long-pulse 755 nm Alexandrite laser in the treatment of venous lake of the lip. STUDY DESIGN/MATERIALS AND METHODS: Forty-one patients (2015-2019) were reviewed. The clinical outcomes were assessed 1 month after the treatment. The efficacy of the treatment was classified into four categories: basic recovery (most optimal outcome), effective, improvement, and ineffective (least favorable outcome). Adverse reactions were also recorded. RESULTS: Thirty-three (80.49%) patients achieved basic recovery and 8 (19.51%) were effective; 29 (70.73%) recovered after receiving one treatment, 3 (7.32%) recovered after receiving two treatments, and 1 (2.44%) recovered after three treatments. CONCLUSION: Long-pulse 755 nm Alexandrite laser is an effective treatment for the venous lake of the lip. Lasers Surg. Med. © 2020 Wiley Periodicals LLC.

RESUMO

The aim of the present study is to describe a case report on the treatment of recurrent herpes using Photodynamic therapy (PDT) and Photobiomodulation as the treatments of choice. A 21-year-old white man checked in in the clinic for evaluation of vesicles arranged in the lower lip skin region. The clinical diagnosis was recurrent herpes and, for treatment, PDT was chosen, using 0.1% methylene blue as a photosensitizer and a pre-irradiation time of five minutes. The Therapy XT laser was used, with a wavelength of 660 nm, power of 100 mW, in a spot area of 0.028 cm², using 4 J energy per point, having been applied on 4 points, one in the center of the lesion and three on its laterals, so that it involved the entire extension of the lesion, totaling 16 J. After 24 hours after the application of the PDT, the patient returned for photobiomodulation with a low-power laser with a wavelength of 660 nm, power of 100 mW, using energy of 1 J per point, for 10 s, being applied on 4 points, totaling 4 J. It was possible to observe complete healing after 10 days of treatment, and the patient remains in follow-up for eight months without any recurrences.

RESUMO

The management of pilon fractures remains challenging owing to the high-energy axial loading mechanism that produces comminution of the articular surface, displacement of tibia metaphysis, and severe soft tissue injury. How to preserve the vitality of soft tissue and achieve anatomic reduction has become a timely issue. We report and evaluate the effect of a modified staging treatment for AO Foundation/Orthopaedic Trauma Association (AO/OTA) 43C1 pilon fracture accompanied by distal fibular and posterior lip of the distal tibia fracture. We performed a modified 2-stage treatment of type C1 pilon fracture with distal fibular and posterior malleolar fractures. In the first stage, the posterolateral incision was used for simultaneous reduction of fibula and posterior malleolus, and the tibia was fixed with an external fixator. In the second stage, the external fixator was removed, and the medial malleolus and tibia were fixed after the edema of soft tissue had subsided. The following data were collected: Foot and Ankle Outcome Score (FAOS), American Orthopaedic Foot & Ankle Society (AOFAS) score, Short Form 36 (SF-36) score, Burwell-Charnley fracture reduction score, and postoperative complications. Twenty-seven patients were monitored for an average of 31.70 ± 7.38 months. The Burwell-Charnley fracture reduction scores had anatomic and fair ratings of 92.59%. SF-36 physical component score was 42.94 ± 12.47 and mental component score was 48.73 ± 9.79. Score data from the multiple scales of FAOS included pain, 88.79 ± 8.59; activities of daily living, 91.89 ± 7.50; quality of life, 90.26 ± 10.52; sports, 87.93 ± 11.64; and symptoms, 85.32 ± 8.65. The AOFAS ankle-hindfoot scores were 87.30 ± 13.45. Complications were reported in 5 patients (18.52%). Our study provides a good alternative to the existing protocol for type C1 pilon fractures with distal fibular and posterior lip of the distal tibia fracture and effectively reduces soft tissue complications.
