Catheter Irrigation

Objectives: To evaluate the effectiveness of mastoidectomy with antibiotic catheter irrigation in patients with chronic tympanostomy tube otorrhea. Methods: A chart review of adult and pediatric patients with persistent tympanostomy tube otorrhea who had failed outpatient medical management and underwent mastoidectomy with placement of a temporary indwelling catheter for antibiotic instillation was performed. Patients were retrospectively followed for recurrent drainage after 2 months and outcomes were categorized as resolution (0-1 episodes of otorrhea or otitis media with effusion during follow-up), improvement (2-3 episodes), or continued episodic (>3 episodes). Results: There were 22 patients and 23 operated ears. Median age was 46 years (interquartile range, IQR = 29-65). The median duration of otorrhea from referral was 5.5 months (IQR = 2.8-12). Following surgery, 14 ears had resolution of drainage, 6 had improvement, and 3 had episodic. The observed percentage of resolved/improved ears (87%) was significant ( P = .0005, 95% CI = 67.9%-95.5%). Median follow-up time was 25 months (IQR = 12-59). Pre and postoperative pure tone averages improved (difference of medians = −3.3 dB, P = .02) with no significant difference in word recognition scores ( P = .68). Methicillin-resistant Staphylococcus aureus was the most common isolated microbe while no growth was most frequently noted on intraoperative cultures. Conclusions: Mastoidectomy with antibiotic catheter irrigation may be an effective surgical strategy, and single stage alternative to intravenous antibiotics, for select patients with persistent tube otorrhea who have failed topical and oral antibiotics.

Air Conduction

A comparison has been made of air conduction threshold changes up to 1 year after myringotomy, aspiration of middle ear fluid, and insertion of ventilation tubes in ten patients with bilateral and 12 with unilateral secretory otitis media (SOM). Pure tone air conduction thresholds have been analyzed in three frequency groups: Low frequency (LF; 0.25, 0.5, and 1 kHz), high frequency (HF; 2,4, and 8 kHz), and extra-high frequency (EHF; 10, 12, 14, and 16 kHz). In the LF and HF ranges, significant improvement came during the first 24 hours after intubation, while in the EHF range, threshold lowering occurred gradually over the following 2 months. Possible explanations for these findings are discussed.

Vestibular Neuronitis

Relationships between middle ear pressure and non-infection-related cochleovestibular dysfunction have been suggested by several authors. According to some data, vertiginous attacks can be prevented by the insertion of a ventilation tube in patients suffering from Meniere's syndrome. The aim of our study was to investigate if the incidence of eustachian tube malfunction and pathologic middle ear pressure is frequent, and if routine implantation of ventilation tubes is reasonable in ears with dysfunctions of the labyrinth, including clinical Meniere's syndrome. So, we determined in our pressure chamber all active and passive parameters of eustachian tube function in 40 patients suffering from Meniere's syndrome, sudden sensory hearing impairment (SSHI), or vestibular neuronitis. Our results disclosed no nonrandom incidence of impaired tubal function among our patients compared to healthy control subjects. Pressure equalization was sufficient in most patients suffering from clinical Meniere's syndrome, and only one patient with vestibular neuronitis presented with a patulous tube. Our results show that impairment of vestibular or cochlear function is not regularly accompanied by eustachian tube dysfunction. Furthermore, no patient reported symptoms while pressure variation was performed. We conclude that variation of middle ear pressure does not usually play a role in the genesis of Meniere's syndrome, vestibular neuronitis, or SSHI. Thus, from our data, we cannot recommend routine implantation of tympanic ventilation tubes in patients suffering from Meniere's syndrome, vestibular neuronitis, or sudden hearing loss.

Bone Conduction Hearing

The use of potentially ototoxic topical drugs is controversial. Few experimental reports of audiometric data from human subjects exist. The purpose of this study is to determine if a significant difference between bone conduction hearing sensitivity before and after otic drop treatment for children with chronic suppurative otitis media and patent ventilation tubes exists. A statistical analysis of sensorineural threshold status after treatment of chronic suppurative otitis media with otic drops is presented.

Mastoid Surgery

The “blue ear drum” generally refers to a condition in which blood or blood products are found in the middle ear. After all possible causes for hemotympanum, including blood dyscrasias and trauma are searched for and ruled out, the patient may have chronic serous otitis media accompanied by bloody effusion. Treatment for all of these patients is conservative, consisting of medical therapy and, if need be, myringotomy and insertion of ventilation tubes. In spite of proper treatment, rarely the condition may progress, over a long period of time, to a state of intractability. Characteristic findings are a hypocellular mastoid, hyperplastic and metaplastic mucoperiosteal lining, including the presence of glands and cysts and Cholesterin granuloma. The recommended procedure is a modified radical mastoidectomy, placement of silicone rubber sheeting in the middle ear and insertion of a ventilation tube. It is to be emphasized that mastoid surgery is rarely indicated for these patients and only after all else has failed.
