Complicaciones ORL severas por mononucleosis infecciosa en adolescentes sanos: 2 casos clínicos y revisión de la literatura / ENT severe complications of infectious mononucleosis in healthy adolescents: report of two cases and literature review

Resumen La mononucleosis infecciosa (MI) es un cuadro clínico generalmente benigno y autolimitado en la infancia y adolescencia debido a la primoinfección del virus de Epstein-Barr caracterizado por la triada de faringitis, fiebre y adenopatías. El riesgo de complicaciones aumenta con la edad y la inmunosupresión, siendo las complicaciones letales más frecuentes las asociadas a rotura esplénica, alteraciones neurológicas y obstrucción de la vía aérea por el aumento del tamaño amigdalar. Los abscesos cervicales asociados a MI son poco frecuentes, siendo mayoritariamente periamigdalinos e intraamigdalares. Presentamos dos casos quirúrgicos de abscesos cervicales profundos de gran tamaño con afectación retrofaríngea y parafaríngea en adolescentes sanos de corta edad (14 y 15 años), sin ningún tipo de inmunosupresión o factores de riesgo, uno de ellos asociado además, a una relevante hemorragia amigdalar espontanea, condición no descrita previamente en la literatura en relación a MI en un paciente tan joven.

Abstract Infectious mononucleosis (MI) is a generally benign and self-limited condition in childhood and adolescence due to the primary EBV infection characterized by the triad of pharyngitis, fever, and lymphadenopathies. The risk of complications increases with age and immunosuppression. The most frequent fatal complications are those associated with splenic rupture, neurological alterations, and airway obstruction due to increased tonsillar size. Cervical abscesses associated with MI are rare, being mostly peritonsillar and intra-tonsil. We present two surgical cases of big deep cervical abscesses with retropharyngeal and parapharyngeal involvement in healthy very young adolescents (14 and 15 years old), without any type of immunosuppression or risk factors, one of them associated with a clinically relevant spontaneous tonsillar bleeding, which had not been described in the literature associated with MI in such young patient.

The CO2 waveguide laser with flexible fiber in transoral resection of oral and oropharyngeal cancers: a retrospective cohort study on postoperative and quality of life outcomes.

The aim of this study was to evaluate the CO2 waveguide laser (WG CO2 laser) with flexible fiber (Lumenis Ltd., Yokneam, Israel) in the treatment of oral and oropharyngeal cancers, specifically focusing on postoperative outcomes, pain, and quality of life (QoL). Eighty-one patients, 43 women and 38 men, with oral or oropharyngeal cancer who consecutively underwent transoral resection by WG CO2 laser from August 2015 to April 2020 were retrospectively enrolled. Resections were performed in super pulsed mode with a power setting ranging between 3 and 10 W. Data about frozen sections, reconstruction, complication rate, length of hospital stay, tracheostomy rate and time to decannulation, nasogastric feeding tube rate and time to oral feeding, pain, and QoL were reviewed. Continuous variables were presented as mean and standard deviation. Concordance between intraoperative frozen section examination and definitive histology was calculated using Cohen's K test of agreement. The mean length of hospital stay was 13 days. The feeding tube rate was 81%; the tracheostomy rate was 35%; the feeding tube was left in place for 8 days on average, and the time to decannulation was 9 days. The only complication was a postoperative bleeding in 4 patients. The median postoperative pain score measured by the Numeric Pain Rating Scale on postoperative days 1, 3, and 5 was 0 and there was a constant decrease in painkiller use over the days. The overall mean composite QoL score was 77 ± 14, with excellent results in saliva, taste, pain, and speech domains. Frozen section evaluation had a specificity of 99% and a negative predictive value of 98%. WG CO2 laser is a good and safe tool for transoral tailored resection of oral and oropharyngeal cancers. It ensures a good overall QoL and guarantees fast recovery and a very low postoperative pain.

Is there a role for ultrasonic surgery in transoral laryngeal cancer resections?

INTRODUCTION: Minimally invasive surgery for laryngeal cancer is nowadays the goal of all larynx surgeons. Transoral laser microsurgery is a widespread and standardized technique that has made it possible to reduce surgical morbidities and hospitalization and to spare laryngeal function. Nonetheless, it has some limitations, which may be exceeded by using new optical and cutting devices as in TransOral UltraSonic Surgery. Areas covered: The aim of this paper is to identify current knowledge about ultrasonic scalpel (US) application in transoral laryngeal surgery and to deduce reasonable indications and contraindications of the tool. Expert opinion: Transoral laryngeal surgery with US is feasible and allows for 'angulated' dissections with higher hemostatic capacity than the CO2 laser. When coupled with an endoscope, surgeons have the possibility to angulate the laryngeal exposure from the inside, reducing blind areas. Nonetheless, US blades are quite bulky, thermal damage is higher than that produced by CO2 laser, and its use should be avoided where the functional result is more closely related to the amount of resected tissue. Tumors limited to the suprahyoid larynx are the current indications for US surgery.
