Our previous report recommended that the management of ipsilateral otitis media with effusion (OME) after maxillary swing nasopharyngectomy was observation. The idea of introducing a stent into the eustachian tube (ET) at the nasopharyngeal side after nasopharyngectomy may prevent postoperative OME. The purpose of this study was to examine the feasibility of intraoperative ET stenting and the efficacy of preventing ipsilateral OME formation.
Prospective cohort study.
From 2009 to 2011, 28 patients with nasopharyngectomy via the maxillary swing approach were recruited. Patients with curative resection were recruited (n = 21). ET stenting was performed intraoperatively using a 16-gauge Angiocath (BD Medical Systems, Franklin Lakes, NJ) with dimensions of 1.7 mm × 30 mm. The stent stays inplace indefinitely. The otologic status was evaluated using otoscopy, pure-tone audiogram, and tympanogram at 3 months, 6 months, and 1 year after the surgery. The outcomes were analyzed and compared with historical control.
There were 9 (43%) patients with no OME at 6 months after surgery, and 15 (71%) patients had no OME at 1 year postoperatively. The results were statistically significant (P < .0001) when compared with our historical control of no ET stenting. There was no incidence of adverse effects of the stenting, such as acute otitis media, dislodgement of the stent, otalgia, and nasal pain.
ET stenting was feasible after nasopharyngectomy. ET stenting prevented a significant number of patients from suffering from ipsilateral OME and alleviated the symptoms of unilateral aural fullness and unilateral conductive hearing impairment up to at least 1 year after the surgery. ET stenting is recommended in all patients after maxillary swing nasopharyngectomy.
