RESUMEN
SUMMARY: Head and cervical spine movements cause narrowing or widening of neuroforamina. In healthy individuals these movements do not cause symptoms of radiculopathy. This implies a compensating volume-regulating mechanism of the neuroforamina. Such a mechanism has been postulated in the years before CT and MRI for the neuroforaminal veins. Dural sac indentations with emptying and refilling of the internal vertebral venous plexus (IVVP) were postulated in the lumbar region using myelography. Emptying of the IVVP occurs in the lumbar spine when moving towards maximal extension and refilling while moving towards maximal flexion. Such indentations have not been shown in the cervical region. With MRI this mechanism has been demonstrated during axial rotation in the C1-C2 segment. It consists of emptying and refilling of the IVVP and thus prevents dural sac compression. During spinal surgery, the IVVP and connecting neuroforaminal veins may be damaged. Because the clinical implications of dysfunction of this protecting mechanism of the IVVP and its neuroforaminal venous connections are not clear, the consequences of such damage are unknown. Therefore, these venous structures should be examined by studying the cervical spine in supine position and, if possible, in different postures (flexion, extension and axial rotation) using MRI with contrast-enhancement and fat suppression. These images may be a basis for future advancement of clinical care.
Los movimientos de la cabeza y la columna cervical provocan un estrechamiento o ensanchamiento de las neuroforaminas. En individuos sanos estos movimientos no causan síntomas de radiculopatía. Esto implica un mecanismo compensador de regulación del volumen de las neuroforaminas. Este mecanismo se ha postulado en los años anteriores a la TC y la RM para las venas neuroforaminales. Mediante mielografía se postularon hendiduras del saco dural con vaciado y llenado del plexo venoso vertebral interno (PVVI) en la región lumbar. El vaciado del PVVI se produce en la columna lumbar cuando se mueve hacia la máxima extensión y se rellena mientras se mueve hacia la máxima flexión. En la región cervical no se han observado tales depresiones. Con resonancia magnética se ha demostrado este mecanismo durante la rotación axial en el segmento C1-C2. Consiste en vaciar y rellenar la PVVI y así evitar la compresión del saco dural. Durante la cirugía de columna, la PVVI y las venas neuroforaminales que las conectan pueden dañarse. Debido a que las implicaciones clínicas de la disfunción de este mecanismo protector de la PVVI y sus conexiones venosas neuroforaminales no están claras, se desconocen las consecuencias de dicho daño. Por tanto, estas estructuras venosas deben examinarse estudiando la columna cervical en decúbito supino y, si es posible, en diferentes posturas (flexión, extensión y rotación axial) mediante resonancia magnética con contraste y supresión grasa. Estas imágenes pueden ser una base para futuros avances de la atención clínica.

La radioterapia de cabeza y cuello posee un rol central en el tratamiento de las neoplasias otorrinolaringológicas, ya sea como tratamiento adyuvante a la cirugía o como terapia definitiva. Dentro de este campo de estudio, un tópico aún poco explorado y motivo de debate, es la indicación de irradiación de los ganglios linfáticos retrofaríngeos, correspondientes a los niveles VIIa y VIIb de cuello. Hemos llevado a cabo una revisión sistemática con el objetivo de dilucidar criterios de irradiación electiva de estos grupos nodales y de emitir recomendaciones en cuanto a su inclusión en la práctica de la radio-oncología.
Radiation therapy has a central role in the management of head and neck malignancies, either as adjuvant treatment after surgery or as definitive therapy. Within this field of study, a still poorly explored and matter-of-debate topic is the indication for irradiation of retropahyngeal lymph nodes, corresponding to neck levels VIIa and VIIb. We have conducted a systematic review with the objective of elucidating elective irradiation criteria for these nodal groups and to issue recommendations about its inclusion in the practice of radiation oncology.

Se informa de un lipoblastoma perineal en una niña de 5 años localizado en el labio mayor derecho. La lesión aumentó gradualmente en 6 meses. En la ecografía y la resonancia magnética (RM), se observó un tumor heterogéneo sólido limitado con componente graso. Tras su extirpación quirúrgica, el estudio anatomopatológico confirmó un lipoblastoma. El lipoblastoma es un tumor mesenquimatoso benigno poco frecuente de la lactancia y la primera infancia. Los síntomas varían en función de la localización; pueden observarse signos de compresión de los órganos adyacentes. Este tipo de tumores inusuales de los tejidos blandos son más frecuentes en menores de 3 años. Los lipoblastomas se localizan predominantemente en las extremidades, pero también pueden encontrarse en la cabeza y el cuello, el tronco, el mediastino, el riñón, el mesenterio, el retroperitoneo y el perineo. Se debe sospechar su presencia en función de los hallazgos de la ecografía y la RM.
We reported a perineal lipoblastoma in a 5-year-old girl located in the right labia mayor. The lesion gradually increased within 6 months. Ultrasound and magnetic resonance imaging (MRI) showed a limited solid heterogenous tumor with fatty component. After it had been surgically removed, the anatomopathological examination confirmed that it was a lipoblastoma. Lipoblastoma is a rare benign mesenchymal tumor of infancy and early childhood. Symptoms vary depending on localization; signs of compression of adjacent organs may be seen. This type of unusual soft tissue tumors occurred most often in under 3 years old. The localization of lipoblastomas is predominantly in the extremities but may be also found in other sites including the head and neck, trunk, mediastinum, kidney, mesentery, retropritoneum and perineum. The suspicion should be considered according to ultrasound and MRI findings.

INTRODUCTION Radiobiological-based optimization functions for radiotherapy treatment planning involve dose-volume effects that could allow greater versatility when shaping dose distributions and DVHs than traditional dose volume (DV) criteria. Two of the most commercially available TPS (Monaco and Eclipse) already offer biological-based optimization functions, but they are not routinely used by most planners in clinical practice. Insight into the benefits of using EUD, TCP/NTCP-based cost functions in Monaco and Eclipse TPS was gained by comparing biological-based optimizations and physical-based optimizations for prostate and head and neck cases. METHODS Three prostate and three H&N cases were retrospectively optimized in Monaco and Eclipse TPS, using radiobiological-based cost functions vs DV-based cost functions. Plan comparison involved ICRU Report 83 parameters D95%, D50%, D2% and TCP for the PTV, and NTCP and RTOG tolerance doses for OARs. RESULTS Although there were differences between Monaco and Eclipse plans due to their dissimilar optimization and dose calculation algorithms as well as optimization functions, both TPS showed that radiobiological-based criteria allow versatile tailoring of the DVH with variation of only one parameter and at most two cost functions, in contrast to the use of three to four DV-based criteria to reach a similar result. CONCLUSION Despite the use of a small sample, optimization of three prostate and three head and neck cases allowed the exploration of optimization possibilities offered by two of the most commercially available TPS on two anatomically dissimilar regions. Radiobiological-based optimization efficiently drives dose distributions and DVH shaping for OARs without sacrifice of PTV coverage. Use of EUD-based cost functions should be encouraged in addition to DV cost functions to obtain the best possible plan in daily clinical practice
INTRODUCCION Las funciones de optimización basadas en radiobiología para la planificación del tratamiento de radioterapia implican efectos dosis volumen que podrían permitir una mayor versatilidad a la hora de dar forma a las distribuciones de dosis y DVH que los tradicionales criterios dosis-volumen (DV). Dos de los TPS más disponibles comercialmente (Mónaco y Eclipse) ya ofrecen productos de funciones de optimización de base biológica, pero la mayoría de los planificadores no las utilizan de forma rutinaria en la práctica clínica. El conocimiento de los beneficios del uso de las funciones de costos basadas en EUD, TCP/NTCP en Mónaco y Eclipse TPS se obtuvo comparando optimizaciones de base biológica y optimizaciones físicas para casos de próstata y cabeza y cuello. MÉTODOS Tres próstatas y tres casos de H&N en Mónaco y Eclipse TPS fueron optimizadas retrospectivamente usando funciones de costos basadas en radiobiología vs funciones de costos basadas en DV. La comparación de planes involucró los parámetros del Informe ICRU 83 D95%, D50%, D2% y TCP para el PTV, y dosis de tolerancia NTCP y RTOG para OAR. Resultados. Aunque hubo diferencias entre los planes Mónaco y Eclipse, debido a sus diferentes algoritmos de optimización y cálculo de dosis, así como funciones de optimización, ambos TPS demostraron que el criterio basado en radiobiología permiten una adaptación versátil del DVH con variación de un solo parámetro y como máximo dos funciones de costos, en contraste con el uso de tres o cuatro criterios basados en DV para alcanzar un resultado similar. CONCLUSIÓN A pesar del uso de una muestra pequeña, la optimización de tres casos de próstata y tres de cabeza y cuello permitió la exploración de las posibilidades de optimización que ofrecen dos de los TPS más disponibles comercialmente en dos regiones anatómicamente diferentes. La optimización basada en radiobiología impulsa de manera eficiente las distribuciones de dosis y la configuración de DVH para OAR sin sacrificar Cobertura de PTV. Se debe fomentar el uso de funciones de costos basadas en EUD además de las funciones de costos DV para obtener el mejor posible plan en la práctica clínica diaria

SUMMARY: Cervical necrotizing fasciitis (NF) is a rare complication of oral cavity infection with high morbi-mortality. Given its low prevalence, adequately reporting cases of NF, its therapeutic management, and associated morphofunctional modifications to the clinical and scientific community is pivotal. To that end, we herein describe a case of cervical NF in a 60-year-old patient with comorbidities and patient presented large, painful cervical swelling associated with a necrotic ulcer lesion in the anterior neck region. Intraoral examination indicated a periodontal abscess in the right mandibular area, while computed tomography indicated the lesion's extension from the right mandibular to the submandibular region. Following empirical intravenous antibiotic treatment, a broad surgical debridement was performed, and the foci of oral infection were removed. Debridement revealed communication between deep and superficial anatomical regions in the submandibular area, where we subsequently placed a Penrose drain. Biopsies showing acute inflammatory infiltrate associated with necrotic and hemorrhagic regions confirmed the diagnosis of NF. When an antibiogram revealed resistance to the empirical treatment, the antibiotic scheme was replaced with an adequate alternative. After a second debridement, we closed the defect with fascio-mucocutaneous advancement flaps with a lateral base while maintaining suction drainage. Having reacted positively, the patient was discharged 10 days after the operation. Despite an extensive morphofunctional change generated in the treated area, the patient showed no difficulties with breathing, phonation, swallowing, or mobilizing the area during control sessions. Altogether, this report contributes to the highly limited literature describing morphological aspects that can facilitate or delay the spread of infection or the morphofunctional disorders associated with the size and depth of surgical interventions for cervical NF, information that is relevant for the comprehensive, long-term prognosis of the treatment of NF.
La fascitis necrosante (FN) cervical es una rara complicación de una infección proveniente de la cavidad bucal asociada a una alta morbimortalidad. Por lo anterior, es fundamental informar a la comunidad clínica y científica los casos de FN, su manejo terapéutico y las modificaciones morfofuncionales asociadas. Se describe un caso de FN cervical en una paciente de 60 años quien presentó una gran tumefacción dolorosa asociada a una lesión ulcerosa necrótica en la región anterior del cuello. El examen intraoral mostró un absceso periodontal en el área mandibular derecha y la tomografía computarizada mostró la extensión de la lesión hacia la región submandibular. Tras el tratamiento antibiótico empírico, se realizó un desbridamiento quirúrgico extenso y se extirparon los focos de infección oral. El desbridamiento reveló comunicación entre las regiones anatómicas profundas y superficiales del área submandibular, donde se colocó un drenaje Penrose. Las biopsias mostraron un infiltrado inflamatorio agudo asociado con regiones necróticas y hemorrágicas, confirmando el diagnóstico de FN. El antibiograma reveló resistencia al tratamiento empírico, por lo que el esquema antibiótico se sustituyó. Tras un segundo desbridamiento, se cerró el defecto con colgajos de avance fascio-mucocutáneos de base lateral manteniendo drenaje aspirativo. El positivo progreso del paciente permitió su alta 10 días después. Aun cuando se generó una gran modificación morfofuncional en el área tratada, la paciente no presentó dificultades para respirar, hablar, deglutir o movilizar el área cervical intervenida durante las sesiones de control. Este informe contribuye a la limitada literatura que describe los aspectos morfológicos que pueden facilitar o retrasar la propagación de la FN y las consecuencias asociadas a los trastornos morfofuncionales provocadas por el tamaño y profundidad de las intervenciones quirúrgicas requeridas por la FN, información relevante para el pronóstico integral a largo plazo del tratamiento de la FN.

Abstract Purpose Several bedside clinical tests have been proposed to predict difficult tracheal intubation. Unfortunately, when used alone, these tests show less than ideal prediction performance. Some multivariate tests have been proposed considering that the combination of some criteria could lead to better prediction performance. The goal of our research was to compare three previously described multivariate models in a group of adult patients undergoing general anesthesia. Methods This study included 220 patients scheduled for elective surgery under general anesthesia. A standardized airway evaluation which included modified Mallampati class (MM), thyromental distance (TMD), mouth opening distance (MOD), head and neck movement (HNM), and jaw protrusion capacity was performed before anesthesia. Multivariate models described by El-Ganzouri et al., Naguib et al., and Langeron et al. were calculated using the airway data. After anesthesia induction, an anesthesiologist performed the laryngoscopic classification and tracheal intubation. The sensitivity, specificity, and receiver operating characteristic (ROC) curves of the models were calculated. Results The overall incidence of difficult laryngoscopic view (DLV) was 12.7%. The area under curve (AUC) for the Langeron, Naguib, and El-Ganzouri models were 0.834, 0.805, and 0.752, respectively, (Langeron > El-Ganzouri, p= 0.004; Langeron = Naguib, p= 0.278; Naguib = El-Ganzouri, p= 0.101). The sensitivities were 85.7%, 67.9%, and 35.7% for the Langeron, Naguib, and El-Ganzouri models, respectively. Conclusion The Langeron model had higher overall prediction performance than that of the El-Ganzouri model. Additionally, the Langeron score had higher sensitivity than the Naguib and El-Ganzouri scores, and therefore yielded a lower incidence of false negatives.

A odontologia reabilitadora tem como um dos seus ramos a especialidade de Prótese Bucomaxilofacial (PBMF), que visa restaurar ou substituir estruturas perdidas na região facial e no sistema estomatognático artificialmente, podendo ser ou não removidos pelo paciente. O presente trabalho objetiva revisar a leitura a respeito da reabilitação com PBMF e a sua aplicabilidade na clínica odontológica. Os indivíduos com alguma perda de estrutura na região de cabeça e pescoço, devido a traumas físicos e/ou químicos, defeitos congênitos, doenças autoimunes, neoplasias, infecções e parasitas, são pacientes para os quais há a indicação da reposição da parte ausente. As reconstruções podem ser perdas intraorais (área da maxila, mandíbula), extraorais (oculopalpebral, ocular, nasal, facial extensa e auricular) ou conjugadas. Esse é um trabalho multidisciplinar, com especialistas de áreas abrangentes e todos os especialistas trabalham de forma conjunta. Pode-se concluir que, embora seja uma das especialidades mais nobres da odontologia, ainda é muito desconhecida por parte dos estudantes e profissionais das áreas da saúde e são próteses absolutamente fundamentais para a reabilitação e qualidade de vida dos indivíduos que tem a necessidade do uso da prótese PBMF(AU)
Rehabilitating dentistry has as one of its branches the specialty of Oral and Maxillofacial Prosthesis (PBMF), which aims to restore or replace structures lost in the facial region and in the stomatognathic system artificially, which may or may not be removed by the patient. The present study aims to review the reading about rehabilitation with PBMF and its applicability in dental clinic. Individuals with some loss of structure in the head and neck region, due to physical and/or chemical trauma, birth defects, autoimmune diseases, neoplasms, infections and parasites, are patients in whom there is an indication for replacement of the absent part. Reconstructions can be intraoral (maximal area, mandible), extraoral (oculopalpebral, ocular, nasal, extensive facial and auricular) or conjugated losses. It is a multidisciplinary work, with specialists from the comprehensive areas and that all specialists work together. It can be concluded that although it is one of the noblest specialties of dentistry, it is still very unknown to students and health professionals, and they are absolutely fundamental prostheses for the rehabilitation and quality of life of individuals who need the use the PBMFprosthesis(AU)

La enfermedad relacionada con inmunoglobulina (Ig) G4 es una enfermedad de reciente conocimiento que puede comprometer cualquier órgano teniendo preferencias por ciertas regiones del cuerpo, donde la región de cabeza y cuello es uno de sus principales puntos afectados, pudiendo comprometer tanto la órbita, glándulas salivales, glándulas lagrimales, glándula tiroides, cavidades paranasales, hueso temporal, faringe y laringe. Este último órgano es infrecuentemente comprometido, solo existiendo 12 casos registrados en la literatura antes de la publicación de este escrito. Presentamos un caso de una mujer de 49 años con historia de disnea frente a esfuerzo, diagnosticándose una estenosis subglótica la cual fue manejada quirúrgicamente con una reconstrucción laringotraqueal. En el estudio histopatológico se evidenció histología compatible con enfermedad relacionada con IgG4, por lo que se inició tratamiento médico con corticotera- pia oral por un lapso de 2 meses en conjunto con inmunología. Paciente luego de 4 años de seguimiento, no ha presentado recaídas, manteniendo un lumen subglótico adecuado.
Immunoglobulin (Ig) G4-related disease is a medical condition of recent knowledge that can compromise any organ, having preferences for certain regions of the body, where the head and neck region is one of the main affected points, being able to affect orbit, salivary glands, lacrimal glands, thyroid gland, paranasal cavities, temporal bone, pharynx and larynx. The latter is infrequently compromised, with only 12 cases registered in the literature before the publication of this writing. We present a case of a 49-year-old woman with a history of exertional dyspnea, diagnosed with a sub- glottic stenosis which was managed surgically with laryngotracheal reconstruction. The histopathological study revealed histology compatible with IgG4-related disease, so medical treatment with oral corticosteroid therapy was started for a period of 2 months in conjunction with immunology. After 4 years of follow-up, the patient has not presented relapses, maintaining an adequate subglottic lumen.

Pseudoaneurysms of the neck are seldom, and those caused by neck infections especially parapharyngeal abscess are even rarer. However, it is life-threatening and may bring sudden death due to the obstruction of airway and the pseudoaneurysms rupture. We analyzed the clinical features, diagnosis and treatment of the disease through a case summary and literature review in order to guide clinical diagnosis and treatment of pseudoaneurysms. The patient, whom we presented was an 87-year-old male and admitted in emergency of our hospital with the chief complaint of neck swelling for 7 days and shortness of breath for 2 days. Cervical ultrasound examination showed that there was an liquid dark area next to the left common carotid artery which was approximately 8.0 cm × 5.0 cm, consideration of formation of left carotid artery pseudoaneurysm, and the liquid dark area which was visible on the right considered of pseudoaneurysm or infection. Angiography of neck showed a clustered high-density shadow around the bifurcation of the left carotid artery, with an overall range of approximately 65 mm × 52 mm × 72 mm, the pseudoaneurysms for sure, while on the right side of the lesion, mixed low density shadows with air could be seen, the parapharyngeal abscess for sure.Then he was diagnosed as the pseudoaneurysm of left internal carotid artery which was caused by parapharyngeal abscess. After tracheal intubation and anti-infection treatment, the patient died due to hemorrhagic shock of the ruptured of the pseudoaneurysm. Morever we performed literature search on PubMed, Wanfang database and CNKI with keywords of "neck pseudoaneurysm, neck infection, parapharyngeal abscess" and enrolled 10 cases. Then we summarized the clinical characteristics and treatment. We analyzed and summarized the 10 case reports, in which the number of male was 7. Among them, there were 4 pediatric, and 6 adults were enrolled overall. Most of the symptoms were neck swelling, and the diseased blood vessel was mainly the right internal carotid artery which accounted for half overall. All the patients underwent surgical intervention, and recovered well. So we draw the conclusion that the clinical incidence of cervical pseudoaneurysms is low and can be caused by a variety of factors, especially caused by infectious factors. When a patient has a progressive pulsating mass in the neck, the preliminary diagnosis should be made by ultrasound as soon as possible, and the aortic enhancement CT should be used to further confirm.For a patient with cervical pseudo-aneurysms caused by parapharyngeal infections, he should take operation timely combined with antibiotic treatment in time.

Objective:To investigate the correlation between preoperative platelet parameters and the clinicopathological features of differentiated thyroid cancer. Methods:We retrospectively analyzed the medical records of patients with thyroid tumors admitted to Zhongda Hospital affiliated to Southeast University and healthy adults with normal physical examination results in our hospital from January 2019 to December 2020, and collected their general information and preoperative blood routine data. Patients with undifferentiated thyroid cancer, diabetes, coronary heart disease, hematological diseases, kidney diseases, autoimmune diseases, genetic diseases, infectious diseases, other systemic tumors, hepatitis or cirrhosis, or those taking anticoagulants were excluded. The exclusion criteria for healthy adults were the absence of the above diseases and normal physical examination results. Differences in platelet parameters among the three groups were compared, and the correlation between clinicopathological characteristics of thyroid cancer, accompanying cervical lymph node metastasis, and platelet parameters of patients was analyzed. A multivariate logistic regression model was used to analyze the risk factors of thyroid cancer with cervical lymph node metastasis. Results:A total of 117 cases of differentiated thyroid cancer were collected, including 33 males and 84 females, with an average age of (41.64±12.25) years; 46 patients had benign thyroid tumors, including 15 males and 31 females, with an average age of (41.35±12.52) years; 50 healthy adults with normal physical examination results in our hospital during the same period were also included, including 18 males and 32 females, with an average age of(42.02±9.62) years, without underlying diseases. The platelet count of the differentiated thyroid cancer group was higher than that of the benign thyroid tumor group(t=-2.219, P=0.028) and the normal control group(t=2.069, P=0.04), while the platelet distribution width of the differentiated thyroid cancer group was lower than that of the benign thyroid tumor group(t=2.238, P=0.027) and the normal control group(t=-2.618, P=0.002). These differences were statistically significant. Preoperative age ≤45 years(χ²=4.225, P=0.04), tumor diameter>1 cm(χ²=4.415, P=0.036), PLT(t=-4.018, P<0.01) increase, and PDW(t=4.568, P<0.01) decrease were significantly correlated with cervical lymph node metastasis of thyroid cancer and had statistical significance. Univariate analysis showed that age ≤45 years(OR=0.447, 95%CI 0.206-0.970, P=0.042), tumor diameter>1 cm(OR=2.3, 95%CI 1.050-5.039, P=0.037), PLT(OR=1.012, 95%CI 1.005-1.019, P=0.001), and PDW(OR=0.693, 95%CI 0.518-0.827, P<0.01) were risk factors for cervical lymph node metastasis of thyroid cancer. The results of multifactorial logistic regression analysis showed that PLT(OR=1.008, 95%CI 1.001-1.016, P=0.026) and PDW(OR=0.692, 95%CI 0.564-0.848, P<0.01) were independent risk factors for thyroid cancer with cervical lymph node metastasis. Conclusion:PLT and PDW may be useful predictive factors for the differentiation of thyroid cancer malignancy and central lymph node metastasis.

Adenoid cystic carcinoma usually occurs in the salivary glands of the head and neck. It is a malignant tumor with a high degree of malignancy, resistance to radiotherapy and chemotherapy and poor prognosis. The clinical course of adenoid cystic carcinoma is slow and easy to be misdiagnosed. The main diagnosis and treatment means are individualized and precise treatment under the multi-disciplinary consultation mode, that is, surgical treatment and radiotherapy and chemotherapy. Adenoid cystic carcinoma is prone to relapse and hematologic metastasis, and the traditional radiotherapy and chemotherapy based therapies have not achieved satisfactory efficacy in the past three decades. How to detect, diagnose and treat early is an urgent task faced by clinicians.

Objective:To compare the clinical effect of transaxillary non-inflatable endoscopic surgery and traditional open thyroid surgery in the treatment of PTC. Methods:A retrospective analysis was performed on 342 patients with PTC treated in the Otorhinolaryngology Department of Qilu Hospital of Shandong University from December 2020 to December 2022. There were 73 males and 269 females, aged 16-72 years, who underwent unilateral non-inflatable transaxillary endoscopic thyroid surgery(endoscopic group) and unilateral traditional open thyroid surgery(open group). There were 108 patients in the endoscopic group and 234 in the open group. Results:The endoscopic group was lower in age(37.1±9.4 vs 43.5±11.2) years and BMI(23.4±3.4 vs 25.7±3.8 )kg/m² than that in the open group, and the difference was statistically significant(t was 5.53, 5.67 respectively, P<0.01). There was no significant difference in hospitalization days between the two groups(P>0.05). The logarithmic curve of the operation time showed a smooth downward trend, and the overall operation time of the endoscopic group was relatively consistent. There was no significant difference in intraoperative blood loss between the endoscopic group(13.3±3.2) mL and the open group(14.7±6.3) mL(P>0.05), but the operation time(130.1±37.9) min was longer than that in the open group(57.4±13.7) min, and the difference was statistically significant(t=19.40, P<0.01). There was no significant difference in complications such as temporary recurrent laryngeal nerve injury within 3 days after operation between the two groups(P>0.05). The aesthetic satisfaction score of the surgical incision and the incision concealment effect score in the endoscopic group were higher than those in the open group, and the difference was statistically significant(P<0.05). Conclusion:Compared with traditional open thyroidectomy, transaxillary non-inflatable endoscopic thyroidectomy has more advantages in the concealment and aesthetics of postoperative incision. Although the former has longer operation time and more drainage, it is still a safe and feasible surgical method with good postoperative clinical effect.

Objective:To investigate the clinical characteristics and surgical treatment outcomes of children with cervical bronchogenic cysts. Methods:A retrospective study of 6 pediatric patients with bronchogenic cysts in the neck region treated in our hospital during 2014 to 2020 was performed. All children underwent complete resection of cervical mass under general anesthesia. Results:There were 6 children, aged from 1 to 5 years, with a median of 2.25 years. There were 3 males and 3 females. The lesions were located on the left neck in 3 cases, the midline neck in 2 cases and the right neck in 1 case. The clinical manifestations were painless mass in 5 cases and recurrent neck infection in 1 case. The size of the mass ranged from 2.1 to 7.5 cm. There was no characteristic clinical or imaging features of bronchogenic cysts. Misdiagnosed as lymphangioma in 3 cases, thyroglossal cyst in 2 cases and piriform fistula in 1 case. The follow-up ranged from 1.50 to 7.75 years, with a median of 4.13 years. All 6 children had no recurrence or complications. Conclusion:Although rare, bronchogenic cysts should be considered in the differential diagnosis of cervical cystic masses in children. Surgery is the most effective way to treat cervical bronchogenic cyst, and histopathological examination is the gold standard for diagnosis.

OBJECTIVE@#To investigate the clinicopathological characteristics and factors influencing the prognosis of non-Hodgkin lymphoma (NHL) in oral and maxillofacial regions.@*METHODS@#Clinicopathological data of 369 patients with oral and maxillofacial NHL initially diagnosed in Peking University Hospital of Stomatology from 2008 to 2020 were collected and analyzed retrospectively.@*RESULTS@#There were 180 males and 189 females. The median age of the patients was 56 years (3 months to 92 years), and the median duration was three months. Clinically, 283 cases manifested as mass, 38 cases as ulcerative necrotizing lesions, and 48 cases as diffuse soft tissue swelling. The lesions of 90 cases located in face and neck (75 cases neck, 20.3%), 99 cases were of major salivary glands (79 cases parotid glands, 20.9%), 103 cases of oral cavity, 50 cases of maxillofacial bones, 20 cases of Waldeyer's ring, and 7 cases of infratemporal fossa. In the study, 247 of the 369 patients had cervical lymphadenopathy, only 40 cases had B symptoms, and 23 cases had the bulky disease. Of the 369 NHLs, 299 (81%) were B-cell NHL, and 70(19%) were T-cell NHL. Diffuse large B-cell lymphoma, extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue, follicular lymphoma, and extranodal natural killer (NK)/T-cell lymphoma nasal type were the most common pathological subtypes. According to Ann Arbor staging, 87, 138, 106, and 38 cases were classified as staged Ⅰ, Ⅱ, Ⅲ, Ⅳ, respectively. The me-dian follow-up time was 48 months, 164 patients died during the follow-up period. The overall survival rates for one year, two years, and five years were 90.1%, 82.4%, and 59.9%, respectively, and the median survival was (86.00±7.98) months. Multivariate analysis showed that age (P < 0.001), Ann Arbor staging (P < 0.001), elevated lactate dehydrogenase (P=0.014), and pathological subtype (P=0.049) were the independent factors influencing the overall survival rate of NHL patients.@*CONCLUSION@#Oral and maxillofacial NHL has unique clinical characteristics and distribution patterns of pathological subtypes. Fewer patients had systemic symptoms. Neck and parotid glands were the most common sites invaded by NHL. Advanced age, Ann Arbor stage Ⅲ-Ⅳ, B symptoms, and T-cell NHL may predict a poor prognosis in oral and maxillofacial NHL patients.

Objective: To explore risk factors affecting treatment for deep neck space infections (DNSIs) so as to provide guidance for appropriate early managements. Methods: A retrospective cohort study was conducted on inpatients with DNSIs admitted to the Department of Otolaryngology, Head and Neck Surgery, Affiliated Hospital of Qingdao University from March 2013 to February 2021. Patients were divided into surgical and non-surgical groups based on whether they had surgery or not. Information collected included demographic data, disease-related signs and symptoms, treatment history, systemic comorbidities, imaging data and laboratory indicators. Hypothesis testing, univariate Logistic regression and multivariate Logistic regression were used for data processing. Resuts A total of 61 patients were included, including 37 males and 24 females, aged 6-96 years. There were 35 cases (57.4%) in the surgical group and 26 cases (42.6%) in the non-surgical group. Multivariate analysis showed that risk factors for surgery as followings: neck dyskinesia (OR=0.03, 95%CI: 0.00-0.24), dysphagia (OR=0.10, 95%CI: 0.02-0.72), serum white blood cell count≥16.74×109/L (OR=1.18, 95%CI: 1.01-1.39) and interspace gas (OR=0.03, 95%CI: 0.00-0.30). Conclusion: Clinicians should be alert to these risk factors for surgery in the course of treatment and timely surgical treatment for patients who meet the conditions.
