Introducción: Los tumores de Senos paranasales y cavidad nasal representan el 0.2% de todos los cánceres; son más frecuentes en hombres y predominantemente unilateral; los tipos histológicos más comunes son el Carcinoma escamocelular y los carcinomas de glándulas salivales menores, dentro del cual, se encuentra el carcinoma adenoideo quístico. Las bases del tratamiento para las lesiones resecables combinan radioterapia y cirugía radical cuyo abordaje puede ser endoscópico, abierto (ej. degloving mediofacial) o la combinación de ambos. Objetivo: Describir un abordaje por degloving para la realización de una maxilectomía parcial y presentarlos resultados de nuestra experiencia clínica en un paciente con una masa en fosa nasal con diagnóstico de carcinoma adenoideo quístico. Diseño: Reporte de caso Materiales y métodos: Se presenta el caso de un varón de 57 años, quien consultó por epistaxis intermitente en fosa nasal izquierda de un año de evolución, con nasosinuscopia que mostró una lesión abombada en tercio medio de cornete inferior y piso de fosa nasal y una lesión violácea en paladar óseo a nivel paramediano izquierdo; identificándose histopatológicamente como carcinoma adenoideo quístico patrón tubular y adenoideo, estadificado como T3N0M0. Se consideró la realizaciónde maxilectomía parcial por abordaje de degloving mediofacial. Resultados: La estancia hospitalaria postquirúrgica fue de 3 días y no presentó complicaciones ni recurrencia hasta la fecha. Conclusiones: El abordaje con degloving mediofacial y maxilectomía parcial, permite resecar el tumor nasosinusal en bloque con márgenes amplios; y la reconstrucción con prótesis, una rápida rehabilitación de la función masticatoria y de resonancia fonatoria.Introduction: Tumors of nasal cavity and paranasal sinuses represent 0.2% of all cancers; they are more common in men and presentation is predominantly unilateral; the most common histological types are the squamous cell carcinoma and carcinoma of minor salivary glands, within which, adenoid cystic carcinoma is located. The basis of treatment for resectable lesions combine radiotherapy and radical surgery whose approach may be endoscopic or open (e.g. midface degloving) or a combination of both. Objective: To describe an approach by degloving to perform a partial maxillectomy and present the results of our clinical experience in a patientwith a mass in left nasal fossa with histopathological diagnosis of Adenoid Cystic Carcinoma. Design: Case report. Materials and methods: We present a case of a 57 year old man, with a history of intermittent epistaxis from the left nasal fossa during a year, whose nasoscopy showed a bulging lesion on the middle third of the inferior turbinate and nasal fossa floor and a purplish lesion on bony palate at paramedian left level; it was identified histologically as adenoid cystic carcinoma with tubular and adenoid pattern, staged as T3N0M0. It was considered to perform a partial maxillectomy by midfacial degloving approach. Results: The postoperative hospital stay was 3 days and there were not any complications or recurrence to date. Conclusions: The approach to midface degloving and partial maxillectomy allows en-bloc resection of sinonasal tumor with wide margins; and prosthetic reconstruction gives a rapid rehabilitation of masticatory function and phonation resonance.

Introduction Sinonasal cancer is very rare and accounts for under 1% of all malignancies of which sinonasal adenoid cystic carcinoma (SNACC) is about 5%. The maxillary sinus is the most common site of SNACC. Misleading symptomatology which overlaps with rhinosinusitis contributes to the delay of diagnosis. Recently, the endoscopic approach is commonly applied with equal or better results to the open approach. Radiofrequency coblation might be used to reduce blood loss. Material and Methods We present a case of an adenoid cystic carcinoma arising from the left inferior turbinate. The patient received endoscopic surgical treatment with the application of radiofrequency coblation in Clarós Clinic at the beginning of 2019 and remains followed up with no sign of recurrence. Afterward, we review the literature on the subject. Conclusion SnACC is a rare malignancy, characterized by slow growth and perineural infiltration with spreading towards the skull base, cavernous sinus, and orbit. The regional nodal involvement is rare. Frequent and delayed distant metastasis in lung, bone, liver, and brain are also typical. Prognosis is poor with the 5-year overall survival between 41%-86%. Surgery with or without complementary radiotherapy provides the best outcomes for the majority of patients. The significance of prognostic factors remains unclear. Lifelong surveillance is obligatory as very late recurrences are common.

Adenoid Cystic Carcinoma is a rare and aggressive tumor representing less than 1% of head and neck cancers. This malignancy often arises from the minor salivary glands, being the palate its most common location. Surgical en-bloc resection with clear margins is the primary treatment. However, this location presents a limited line of sight and a high risk of injuries, making the surgical procedure challenging. In this context, technologies such as intraoperative navigation can become an effective tool, reducing morbidity and improving the safety and accuracy of the procedure. Although their use is extended in fields such as neurosurgery, their application in maxillofacial surgery has not been widely evidenced. One reason is the need to rigidly fixate a navigation reference to the patient, which often entails an invasive setup. In this work, we studied three alternative and less invasive setups using optical tracking, 3D printing and augmented reality. We evaluated their precision in a patient-specific phantom, obtaining errors below 1 mm. The optimum setup was finally applied in a clinical case, where the navigation software was used to guide the tumor resection. Points were collected along the surgical margins after resection and compared with the real ones identified in the postoperative CT. Distances of less than 2 mm were obtained in 90% of the samples. Moreover, the navigation provided confidence to the surgeons, who could then undertake a less invasive and more conservative approach. The postoperative CT scans showed adequate resection margins and confirmed that the patient is free of disease after two years of follow-up.

Background and aim Cold snare polypectomy (CSP) is growing in popularity due to its safety and convenience. Its indication is benign tumours such as adenoma and sessile serrated lesions (SSLs) <10 mm in size. CSP for SSLs ≥10 mm in size has not been well examined. In this study, we aimed the feasibility of this treatment regarding therapeutic results and local recurrence. Methods This was a single-centre retrospective cohort study. We reviewed SSLs with or without dysplasia of 10–20 mm that were resected by CSP from 2014 to 2020. All tumours were diagnosed endoscopically as SSLs without dysplasia before CSP with the help of magnifying narrow band imaging or blue laser imaging. We analysed the lesion characteristics, en bloc resection, histopathological diagnosis, adverse events and local recurrence. We analysed risk factors for recurrence, comparing recurrent lesions to non-recurrent lesions. We also compared risk factors for lesions 10–14 mm in size to those for lesions 15–20 mm in size. Results We analysed 160 lesions in 100 patients ( Mage± SD=67.7±10.1 years). The polyp size ( M± SD) was 11.8±2.8 mm, and the en bloc resection rate was 60.0% (96 cases). The rates of massive perioperative haemorrhage, postoperative haemorrhage and perforation were 1.3%, 0% and 0%, respectively. Regarding histopathological diagnosis, two (1.2%) cases showed SSLs with high-grade dysplasia. The recurrence rate in 101 lesions with a median follow-up period of 18 months (interquartile range 12–24 months) was 5.0%. There were no significant risk factors such as tumour size, location, morphology and so on in terms of recurrence. All recurrent cases could be resected by repeat CSP. The recurrence rates of lesions 10–14 mm in size and 15–20 mm in size were 4.7% and 6.3%, respectively ( p=0.713). Conclusion CSP of SSLs ≥10 mm in size according to magnifying endoscopic diagnosis was safe and promising, but the rate of recurrence was slightly high, meaning that close follow-up is required.

Adenoid cystic carcinoma is a cancer of the salivary gland that primarily affects the parotid, submandibular, and accessory salivary glands. Its growth is slow and it has infiltrative nature. A 46-year-old female patient coming from the rural area presented a lesion on the palate and reported pain in the region for three years. After incisional biopsy, and histopathological diagnosis of adenoid cystic carcinoma of the cribriform type of minor salivary gland, superior hemimaxillectomy and adjuvant treatment with radiotherapy and maxillofacial prosthetic rehabilitation were performed.

A 71-year-old woman was admitted with angina pectoris. During hospitalization she developed a myocardial infarction (NSTEMI). Laboratory results revealed a mild elevated troponin and an elevated calcium level (3.35 mmol/l). Subsequently, there was a decreased phosphate (0.36 mmol/l [normal 0.81-1.62 mmol/l]) as well as 16-fold elevated serum level of parathyroid hormone (PTH, 1156 ng/l [normal 10-73 ng/l]), indicating a primary hyperparathyroidism. Sonographically a thyroidal node was detected, not clearly demarcated (TIRADS 5). FNA showed a monomorphic, partial follicular cell population with an immunohistochemical positivity for PTH. Magnetic resonance imaging (MRI) showed a 5 cm large tumor at the right caudal pole of the thyroid with compression of the dorsolateral trachea without infiltration. Surgical removal with en bloc resection of the right hemithyroid with parathyroidectomy was performed. Postoperatively the PTH level dropped to 12.1 ng/l. Pathological examination revealed a 5 cm tumor with infiltration of the thyroid and a perineural invasion. The diagnosis of a presymptomatic parathyroid carcinoma could be established. The affirmative histopathological diagnosis of a parathyroid carcinoma can be challenging and is limited to tumors with evidence of invasive growth in adjacent structures such as the thyroid and/or soft tissue, perineural spaces, angioinvasion of capsular and/or extracapsular vessels, and/or documented metastases.
