Postoperative Pain in Adult Tonsillectomy: Is There Any Difference Between the Technique?

Tonsillectomy is one of the most common surgical procedures performed worldwide. Several techniques have been developed to reduce morbidity and enhance recovery after tonsillectomy. Our study was designed to compare post-operative pain with three different techniques: cold dissection (CD), monopolar-bipolar dissection (MBD) and coblation dissection (CBD). 103 adults were scheduled for elective tonsillectomy from September 2014 to December 2015, and were randomized to CD, MBD and CBD. Post-operative pain was assessed using visual analogue scale (VAS) and Lattinen Test (LT). We did not find significant differences between the groups in the VAS pain scores (p > 0.05), except for the first day, when CBD tonsillectomy showed a higher pain score (p < 0.05). The differences in LT scores between the three techniques were not statistically significant (p > 0.05). Comparison of analgesic consumption between CD, MBD and CBD did not found any significant differences irrespective of the technique used. When first and second week after surgery were compared, differences in analgesics requirements were statistically significant (p < 0.05). Seventeen cases (16.5%) of secondary haemorrhage were reported, but there were no statistical differences in the rate of postoperative bleeding between the three groups (p > 0.05). We conclude that in our study comparison of the three techniques, CD, MBD and CBD, did not show significant differences in the post-tonsillectomy pain scores and bleeding rate.

Management of vagal paragangliomas: review of 17 patients.

Vagal paragangliomas are very rare benign vascular tumors of neuroendocrine nature, and are much less frequent than carotid and jugulo-tympanic tumors. The goal of this retrospective study is to review the clinical and genetic findings, surgical treatment, and complications of vagal paragangliomas, as well as to discuss the management options. During the period 1990-2013, 17 patients with vagal paragangliomas were referred to our institution. There were ten patients with isolated tumors, and seven with multicentric paragangliomas. There were nine women and eight men. Mean age of patients was 51.4 years. Five cases had a positive family history of paraganglioma (29.4 %). Germline mutations of SDH genes were found in six of our patients (35.3 %). Many options were considered in the management of vagal paragangliomas. Surgical treatment was performed in 11 young patients (64.7 %) using different approaches: in 4 patients the tumor was resected through a transcervical approach; in 3 through a transcervical-transmandibular approach; in 1 it was resected using a transcervical-transmastoid approach, and in 3 a type A infratemporal fossa approach was performed. In all operated cases, the removal of the tumor led to sacrificing of the vagus nerve. Postoperative hypoglossal nerve deficit was reported in 4 cases (36.3 %). In six elderly patients (35.3 %), we decided to "wait-and-scan" in order to avoid creating greater morbidity than that of the tumor itself. Many factors should be considered in the treatment of vagal paragangliomas: the age and general condition of the patient, the biological behavior of the tumor, tumor size, genetic results, bilaterality, multicentricity, lower cranial nerve function, and of course the potential morbidity of the surgical treatment itself. Rehabilitation and, possibly surgery, are necessary to treat postoperative lower cranial nerve deficits.

Manejo conservador del schwannoma vestibular / Conservative management of vestibular schwannoma

Introducción: El schwannoma vestibular (SV) es un tumor benigno de lento crecimiento originado en el VIII par craneal, en cuyo tratamiento entran a formar parte la microcirugía, la radioterapia estereoatáxica, y el manejo conservador de los tumores con controles radiológicos periódicos. Material y métodos: Estudio retrospectivo de pacientes con SV siguiendo un manejo conservador en un hospital de tercer nivel entre los años 1993-2013.Un total de 73 pacientes fueron incorporados a nuestro protocolo de seguimiento de SV. La edad media al diagnóstico fue de 59,7 años. El tamaño medio de 11,9 mm (4-27 mm), siendo el 58,9% intracanaliculares y el 41,1% extracanaliculares. El periodo de seguimiento medio fue de 35,75 meses. Resultados: En el 87,7% no hubo evidencia de crecimiento tumoral. Un total de 9 (12,3%) tumores incrementaron sus dimensiones. La velocidad media de crecimiento fue de 0,62 mm/año. El porcentaje de tumores extracanal que crecieron (20%) fue mayor que el de los tumores intracanal (7%). Siete pacientes experimentaron cambios significativos en su sintomatología (9,5%) y 6 de estos una pérdida de la audición útil (8,2%). Seis pacientes salieron del seguimiento y fueron intervenidos quirúrgicamente (8,2%). Conclusión: El seguimiento del SV con controles periódicos de resonancia magnética nuclear representa una opción válida de manejo, dado que la mayoría de los tumores de pequeño tamaño experimentan poco o nulo crecimiento a lo largo del tiempo (AU)

Introduction: Vestibular schwannoma (VS) is a benign, slow-growing tumour originating in the 8 th cranial nerve. The treatment includes microsurgery, stereotactic radiotherapy and conservative management of tumours with periodic radiological tests. Methods: This was a retrospective study of patients with VS following conservative management in a tertiary hospital between 1993 and 2013. A total of 73 patients were enrolled in our protocol. The mean age at diagnosis was 59.7 years. The average size was 11.9 mm (4-27 mm); 58.9% of the tumours were intracanalicular and 41.1%, extracanalicular. The mean follow-up period was 35.75 months. Results: In 87.7% of patients there was no evidence of tumour growth. A total of 9 tumours (12.3%) increased in size. The average growth rate was 0.62 mm/year. The percentage of extracanalicular tumours that grew (20%) was higher than that of intracanalicular tumours (7%). Seven patients (9.5%) experienced significant changes in their symptoms and 6 of these (8.2%) experienced a loss of useful hearing. Six patients (8.2%) left follow-up and underwent surgery. Conclusions: Periodic monitoring of vestibular schwannomas with magnetic resonance imaging represents an option for management, because most small tumours experience little or no growth over time (AU)
