ABSTRACT
ABSTRACT Objective: Paragangliomas are slow-growing tumours that present with varied clinical spectra. Early recognition is paramount in achieving reduced morbidity and mortality. There is a paucity of data regarding head and neck paragangliomas (HNPGs) in the Caribbean literature. This study aimed to reflect the clinical experience in the management of HNPGs at two Jamaican tertiary referral centres: the Kingston Public Hospital (KPH) and the University Hospital of the West Indies (UHWI). Methods: A retrospective analysis was conducted on all patients presenting to the Ear, Nose and Throat (ENT) departments of the UHWI in 2004-14 and of the KPH in 2012-14 with the diagnosis of a HNPG. Results: There were 15 patients, 1 male and 14 females. The average age at presentation was 47.1 years. The HNPGs in this series included eight patients with glomus tympanicum (GT, 53%), four with glomus jugulare (GJ, 27%), two with carotid body tumours (CBTs, 13%) and one with glomus vagale (GV, 7%). Eight patients underwent surgical resection (two CBTs, four GT and two GJ). Treatment outcomes achieved included: complete resection (four patients), stable with residual disease (two patients), and recurrence (two patients). Seven patients were awaiting definitive treatment, one patient with GJ was referred overseas, and one patient with GV defaulted. Conclusion: Glomus tympanicum is the most common HNPG in this series which contrasts with that of most international series. Despite the limitations within this region, such as limited access to angio-embolization and stereotactic modalities, the management outcomes are similar in some respects to the reported international literature.
RESUMEN Objetivo: Los paragangliomas son tumores de crecimiento lento que se presentan con variados espectros clínicos. Su detección precoz es fundamental para lograr una reducción de la morbilidad y la mortalidad. Hay escasez de datos con respecto a los paragangliomas de cabeza y cuello (PgCC) en la literatura del Caribe. Este estudio tuvo como objetivo reflejar la experiencia clínica en el tratamiento de PgCC en dos centros de remisión terciarios de Jamaica: jamaiquinos: el Hospital Público de Kingston (KPH) y el Hospital Universitario de UWI (HUWI). Métodos: Se llevó a cabo un análisis retrospectivo de todos los pacientes diagnosticados con PgCC que acudieron a los Departamentos de Otorrinolaringología de HUWI en 2004-14 y de KPH en 2012-14. Resultados: Hubo 15 pacientes - 1 varón y 14 hembras. La edad promedio al momento de presentarse fue 47.1 años. El PgCC en esta serie incluyó a ocho pacientes con glomus timpánico (GT, 53%), cuatro con glomus yugular (GY, 27%), dos con tumores del cuerpo carotídeo (TCC, 13%), y uno con glomus vagal (GV, 7%). Ocho pacientes fueron sometidos a resección quirúrgica (dos TCC, cuatro GT, y dos GY). Los resultados logrados con el tratamiento incluyeron: resección total (cuatro pacientes), estables con enfermedad residual (dos pacientes), y recurrencia (dos pacientes). Siete pacientes esperaban un tratamiento definitivo, un paciente con GY fue remitido al extranjero, y un paciente con GV no se presentó. Conclusión: El glomus timpánico es el PgCC más común en esta serie que contrasta con el de la mayoría de las series internacionales. A pesar de las limitaciones dentro de esta región, tales como el acceso limitado a la angioembolización y las modalidades estereotácticas, los resultados del manejo de la enfermedad son similares en algunos aspectos a la literatura internacional reportada.

Objective To summarize the condition of surgical treatment and prognosis of 54 cases of jugular foramen tumors in the past 5 years.Methods All 54 cases were treated with operation by Fisch approach.Thirty-eight cases underwent total or near total resection of the tumor.Most resection of the tumor was underwent in 16 cases,in which,7 cases underwent postoperative radiotherapy or gamma knife therapy.The facial nerve monitoring was used in all cases.The facial nerve was anatomized and shifted in 35 cases,was just anatomized like a bridge in 10 cases,and was excised partly in 9 cases,in which,4 cases underwent facial-hypoglossal nerve anastomosis and 3 cases underwent transplantation of facial nerve and great auricular nerve.Results The external auditory canal was closed in 41 cases.The near pedicled temporalis muscle flap was obliterated in the operating cavity in 35 cases.Six cases underwent fat filling in the operating cavity.Eighteen patients showed facial palsy in varying degrees after operation.Among them,14 cases improved to different extents in 2 weeks to 9 months and 4 cases did not improve.One case showed recurrent laryngeal nerve paralysis in the same side before operation and improved in half a year after operation.Postoperative subcutaneous hematoma occurred in 2 cases,wound infection in 1 case.All the cases improved by debridement suture and anti-infective therapy.The cavity filling necrosis occurred in 2 cases,which recovered after debridement and dressing.For half a year after operation,except 9 cases of residual or recurrent,and the rest showed no recurrence.Conclusion The Fisch approach of surgical treatment of jugular foramen tumors can provid good exposure,clear vision,facilitate hemostasis.The skills of intraoperative facial nerve monitoring,facial nerve anatomy like a bridge or anatomy and shift when necessary are beneficial to the total or nearly total resection of tumor and reduce the injury of facial nerve.The operating cavity filling and selective external auditory canal closure can effectively reduce the surgical cavity effusion and the incidence of postoperative infection.
