Reconstructive Option

<b><i>Introduction:</i></b> Mandibular defects reconstruction could result challenging in childhood, due to facial and mandibular growth patterns. For these reasons, the choice of the most suitable reconstructive option in pediatric patients, affected by mandibular malignancies, still objects of debate. <b><i>Objective:</i></b> The aim of our study was to compare our reconstructive schedules to the existing literature in order to give a personal contribute to the present panorama. <b><i>Methods:</i></b> We performed, in October 2019, a retrospective evaluation of pediatric patients treated for biopsy-proven mandibular malignancies at our Institute between January 2013 and December 2016. All of them received multimodal therapy in accordance with standard guidelines and their demographic, clinical, treatment, and outcome parameters were collected and analyzed. <b><i>Results:</i></b> We observed a shorter duration of surgery, a faster tracheostomy tube and feeding-tube removal, and a minor hospitalization in patients who received grafts transfer compared to those who underwent microsurgical mandibular reconstruction. After a 36-month period of follow-up, osteochondral grafts showed a pattern of growth similar to the mandibular epiphysis (condilylion-gonion linear and vertical ratio ranging to 0.96–1.03 and 1–1.02 at orthopantomogram, respectively). No bone consolidation delays and functional impairment were recorded. <b><i>Conclusions:</i></b> Free flaps mandibular reconstruction in children needs to be better assessed and proximal fibular epiphyseal free flap indication might deserve further studies. Osteochondral grafts find indication for lateral defects, 50–55 mm in maximum length and located in the mandibular ramus, without massive teeth or soft tissue defect. Condyle involvement does not represent an absolute contraindication to rib graft use.

OBJECTIVE The middle fossa transpetrosal approach to the petroclival and posterior cavernous sinus regions includes removal of the anterior petrous apex (APA), an area well studied in adults but not in children. To this end, the authors performed a morphometric analysis of the APA region during pediatric maturation. METHODS Measurements of the distance from the clivus to the internal auditory canal (IAC; C-IAC), the distance of the petrous segment of the internal carotid artery (petrous carotid; PC) to the mesial petrous bone (MPB; PC-MPB), the distance of the PC to the mesial petrous apex (MPA; PC-MPA), and the IAC depth from the middle fossa floor (IAC-D) were made on thin-cut CT scans from 60 patients (distributed across ages 0–3, 4–7, 8–11, 12–15, 16–18, and > 18 years). The APA volume was calculated as a cylinder using C-IAC (length) and PC-MPB (diameter). APA pneumatization was noted. Data were analyzed by laterality, sex, and age. RESULTS APA parameters did not differ by laterality or sex. APA pneumatization was seen on 20 of 60 scans (33.3%) in patients ≥ 4 years. The majority of the APA region growth occurred by ages 8–11 years, with PC-MPA and PC-MPB increasing 15.9% (from 9.4 to 10.9 mm, p = 0.08) and 23.5% (from 8.9 to 11.0 mm, p < 0.01) between ages 0–3 and 8–11 years, and C-IAC increasing 20.7% (from 13.0 to 15.7 mm, p < 0.01) between ages 0–3 and 4–7 years. APA volume increased 79.6% from ages 0–3 to 8–11 years (from 834.3 to 1499.2 mm3, p < 0.01). None of these parameters displayed further significant growth. Finally, IAC-D increased 51.1% (from 4.3 to 6.5 mm, p < 0.01) between ages 0–3 and adult, without significant differences between successive age groups. CONCLUSIONS APA development is largely complete by the ages of 8–11 years. Knowledge of APA growth patterns may aid approach selection and APA removal in pediatric patients.

Tissue Defects

Extensive soft tissue defects following trauma, burn or after cancer surgery need coverage by flaps. Sometimes surrounding tissues are not healthy enough or quantity is not favorable to provide adequate pedicle flaps. Microvascular free flap can provide healthy tissue of adequate amount from distant area for those difficult situations.15 microvascular free flaps were performed from October 2011 to February 2013. Radial forearm free flap was done in 8 and Latissimusdorsi (LD) flap in 7 cases. 10 flaps done in foot, ankle & lower leg region (radial forearm-5, LD-5) and 5 flaps were done in face and scalp region (radial forearm-4, LD-1).12 flaps healed uneventfully with good coverage of the defect. Average ischemia time was 135 min (range 100-240 min) and average anastomosis time was 75 min (average 60-100 min). 2 flaps failed. There was necrosis of the tip of 2 LD and cumbersome swelling of the flap was found in 2 cases of LD flaps.Large soft tissue defect of body where local or regional flaps are not feasible; can be easily covered with free flaps. Its capacity to cover huge soft tissue defect has neutralizes its technical demand. Though complications are still high in our hands; can be reduced performing more number of cases.

Background: Unplanned return to the operating room (uROR) within the 30-day postoperative period can be used as a quality indicator in pediatric surgery. The aim of this study was to investigate and evaluate uROR as a quality indicator. Methods: The case records of pediatric patients who underwent reoperation within the 30-day period after primary surgery, from 1 January 2018 to 31 December 2020 were retrospectively reviewed. The primary outcome of the study was the rate of uROR as a quality indicator in pediatric surgery. Secondary outcomes were indications for primary and secondary surgery, types and management of complications, factors that led to uROR, length of hospital stay, duration of surgery and anesthesia, and starting time of surgery. Results: A total of 3982 surgical procedures, under general anesthesia, were performed during the three-year study period (2018, n = 1432; 2019, n = 1435; 2020, n = 1115). Elective and emergency surgeries were performed in 3032 (76.1%) and 950 (23.9%) patients, respectively. During the study period 19 (0.5%) pediatric patients, with the median age of 11 years (IQR 3, 16), underwent uROR within the 30-day postoperative period. The uROR incidence was 6 (0.4%), 6 (0.4%), and 7 (0.6%) for years 2018, 2019, and 2020, respectively (p = 0.697). The incidence of uROR was significantly higher in males (n = 14; 73.7%) than in females (n = 5; 26.3%) (p = 0.002). The share of unplanned reoperations in studied period was 4.5 times higher in primarily emergency surgeries compared to primarily elective surgeries (p < 0.001). The difference in incidence was 0.9% (95% CI, 0.4–1.4). Out of children that underwent uROR within the 30-day period after elective procedures, 50% had American Society of Anesthesiologists (ASA) score three or higher (p = 0.016). The most common procedure which led to uROR was appendectomy (n = 5, 26.3%) while the errors in surgical technique were the most common cause for uROR (n = 11, 57.9%). Conclusion: Unplanned reoperations within the 30-day period after the initial surgical procedure can be a good quality indicator in pediatric surgery. Risk factors associated with uROR are emergency surgery, male gender, and ASA score ≥3 in elective pediatric surgery.

Os defeitos mandibulares devido à ressecção de lesão óssea interferem a harmonia e estética facial comprometendo a qualidade de vida dos pacientes. Grandes defeitos exigem planejamento minucioso, principalmente quando lançamos mão de enxertos e placas de reconstrução, evitando assim resultados insatisfatórios ou até mesmo sequelas. Apesar de algumas classificações dos defeitos mandibulares vêm sendo discutidas ao longo dos anos, ainda não há um protocolo definido para reconstrução mandibular. O uso de prototipagem na Cirurgia Bucomaxilofacial tem se tornado cada vez mais frequente; a precisão da reconstrução, diminuição do tempo de cirurgia reflete em recuperação mais rápida do paciente. Mesmo com a ferramenta da prototipagem, grandes lesões e perdas ósseas permanecem como grande desafio ao cirurgião.  O objetivo deste trabalho é relatar um caso clínico de reconstrução mandibular no qual houve a necessidade de ser tratado com remoção de placa de reconstrução e nova reabilitação cirúrgica do paciente.Descritores: Mandíbula; Reconstrução Mandibular; Modelos Biológicos.ReferênciasSantos LCS, Seixas AM, Barbosa B, Cincura RNS.

Purpose The gold-standard for reconstruction of large mandibular defects is the use of free flaps of vascularized autologous bone with the fibula as the preferred donor site. The use of "custom cutting guides" for this indication is becoming increasingly prevalent. But cost of the procedure averages around 2,500 dollars per patient excluding treatment and entails selection criteria. We think it is possible to standardize mandibular reconstructions from an anatomical mean. The objective of this study was to perform a mandibular morphometric analysis in order to obtain a set of "mean" measurements, which can be used by all surgeons interested in mandibular reconstruction. Methods We performed a morphometric analysis consisting of three-dimensional mandibular reconstructions of 30 men and 30 women. Several reference points were set and defined to evaluate specific lengths and angles of interest. We conducted an intra and inter-sexual descriptive analysis of measurements obtained. Results We did not identify any major intra-sexual differences within each group. The gonial angle is more open in women and the measurements characterizing the basilar contour are more prominent in men. We did not identify any differences in alveolar region parameters. Conclusion The results of this study constitute a morphological tool for surgeons, from bone graft to free flap. These results also confirm us that the use of «custom cutting guides» for mandibular reconstruction may be excessive. It is pertinent to examine the value of "custom made" mandibular reconstructions since the differences observed are of the order of millimeters.

Tissue Defects

Extensive soft tissue defects present a dif!cult problem to the plastic surgeon as they are usually associated with exposed important structures such as vessels, nerves, tendons, joint cavity or bone. Reconstruction of soft tissue defects have a wide range of therapeutic options. We reconstructed soft tissue defect in many areas using free anterolateral thigh flap (ALTF). From Februari 2009 - 2010, 9 cases of soft tissue defects in the face, neck, leg and foot of various etiologic factors were admitted to the plastic and reconstructive surgery unit, Cipto Mangunkusumo general hospital. Trauma is the commonest cause of soft tissue defects of the lower extremity, followed by tumours. The cruris was the commonest site (4 cases, 44,4%). Flap success rate was 66,67 %. Failure was reported 1 cases in this study due to vein compromise. In our hospital, we are quite familiar with Anterolateral thigh flap (ALTF) even though the case is limited. Anterolateral thigh flap (ALTF) is used for reconstruction of various simple and complex soft tissue defects, for big and small defects with cavity (orbita).
