RESUMEN
Objetivo:
Comparar los resultados de timpanoplastia entre fascia temporal (GI) y cartílago auricular (GII) en perforación timpánica secundaria a trauma por onda explosiva.Diseño:
Estudio de cohorte histórica.Métodos:
Se incluyeron pacientes llevados a timpanoplastia tipo I, intervenidos entre febrero 1.º del 2007 y diciembre 31 del 2009. Los sujetos son miembros de las Fuerzas Armadas de Colombia, heridos en combate. Fueron excluidos aquellos sometidos a mastoidectomía u osciculoplastia. El resultado anatómico se evaluó mediante prueba exacta de Fisher, y el funcional, mediante Anova.Resultados:
Se incluyeron 36 sujetos, GI = 16 y GII = 20. No hubo diferencias en el éxito anatómico entre GII = 95% (19/20) y GI = 87,5% (14/16), a los 12 meses (p = 0,57). En pacientes con cadena íntegra-móvil, la brecha aire-hueso a los seis meses (n = 30) fue de 5,8 dB (DE = 8 dB), y a los doce meses (n = 26) fue de 5,4 dB (DE = 8 dB). No hubo asociación entre el resultado funcional y el tipo de injerto utilizado (p > 0,05).Conclusiones:
la timpanoplastia en perforación secundaria a trauma por onda explosiva ofrece resultados satisfactorios y estables a los doce meses, tanto con fascia como con cartílago...ABSTRACT
Objective:
to compare tympanoplasty outcomes between fascia temporalis (GI) and auricular cartilage (GII) in tympanic membrane perforation caused by blast injury.Design:
historical cohort study.Methods:
patients underwent tympanoplasty type I, between February 1-2007 and December 31-2009, were included. The study subjects are members of the armed forces of Colombia that were wounded in combat. Patients who underwent mastoidectomy or ossiculoplasty were excluded. The Fishers exact test was performed to assess the anatomical outcome, and the ANOVA test to assess the functional outcome.Results:
36 subjects were included, GI = 16 and GII = 20. Regarding the anatomical success, there was no differences between GI = 95% (19/20) and GII = 87.5% (4/16), at 12 months of follow-up (p = 0.57). In patients with an intact ossicular chain, the airbone gap at 6 months (n = 29) was = 5.8 dB (SD = 8 dB); while at 12 months (n = 26) it was = 5.4 dB (SD = 8 dB). There was no relationship between the functional outcome and the kind of graft used (p > 0.05).Conclusions:
the surgical outcomes of the tympanoplasty in tympanic membrane perforation caused by blast injury are satisfactory and stable at 12 months, with fascia and cartilage...Key words
