Shah and Shepard ventilation tubes are the two most commonly used ventilation tube in current practice. In some centres these two tubes are used interchangeably, in others the Shepard is often used as the first ‘grommet’ of insertion and the Shah for subsequent insertions. A study was undertaken of extrusion rate of these ventilation tubes in 180 children who had surgery for Serous otitis media in 1987. Extrusion time was found to be very significantly different between these tubes. The Shah ventilation tube remains in situ 3 months longer than the Shepard. A case is made for the use of Shah ventilation tubes as the first “grommet” of insertion. Otorrhoea following insertion of ventilation tube did not affect the extrusion rate of ventilation tubes in this study. Nor has otorrhoea a predilection for any particular ventilation tube.

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.

AbstractObjective:To demonstrate that ventilation tubes can remain in situ much longer than expected, and that the materials used in the manufacturing of these tubes can degrade and cause complications. Long-term follow up and replacement of the tube is recommended.Method:Case report and review of the literature concerning the use of long-term ventilation tubes.Results:In the case reported, the ventilation tube was in place for 19 years, which resulted in chronic ear discharge. When it was removed, it was noted that the tube itself had degraded and had caused a chronic inflammatory reaction.Conclusion:We recommend that the long-term use of ventilation tubes is followed up and that the tube is replaced before material degradation takes place.

Objective: To further understand the roles of bacteria and antibiotics in the development of otitis media with effusion (OME).Methods: Samples of middle-ear effusion (MEE) were collected during the placement of ventilation tubes to treat chronic OME. Children with acute otitis media within the past three months were excluded from this study. We used polymerase chain reaction (PCR) to detect pathogens and to test the susceptibility of Streptococcus pneumoniae to penicillin.Results: Among MEE samples from 52 children, PCR detected bacterial DNA in 32 per cent (24/75) of them. S. pneumoniae was detected more frequently in middle ears that required ventilation tube insertion at least twice compared with those requiring ventilation tube insertion only once (5/15 versus 4/60; p = 0.013). Higher levels of S. pneumoniae were detected in MEE from children with, than without, a long history of antibiotic administration (7/10 versus 2/14; p = 0.0187). The pbp genes of all isolated S. pneumoniae contained mutations.Conclusions: Long exposure to antibiotics might significantly influence the bacterial genome in MEE.

A new heat myringotomy device is described that produces a 2-mm myringotomy which remains open three to four weeks without the need for a ventilation tube. The device can be used in the office in young children under iontophoretic anesthesia and may eliminate the need for tube insertion in 50% of chronic serous otitis media cases.

Aggressive otologic management has been recommended for children with cleft palate because of the almost universal occurrence of otitis media with effusion (OME) in these children and the association of OME with hearing loss and possible language, cognitive, and academic delays. In this study, 28 children with cleft palate and 29 noncleft children were seen at 3-month intervals from 9 to 30 months to compare otologic treatment and management. Hearing and middle ear function were tested at each session; information on ventilation tube placement was obtained from medical records. Ventilation tubes were placed earlier and more often in children with cleft palate, but children with cleft palates failed the hearing screening more often. The correlation between age at first tube placement and frequency of hearing screening failures was significant for the children with cleft palate, indicating that the later tubes were first placed, the poorer the child's hearing.

AbstractVentilation tube (VT) insertion is an accepted treatment for chronic otitismedia with effusion (OME) in children. One hundred and eighty five children with bilateral OME were treated by unilateral myringotomy and VT insertion with no treatment to the contralateral ear. During a 5 year follow-up 95 of the children required only one VT but the remainer required more than one but always treatment was carried out to the same ear. The rate of development of tympanosclerosis was measured and scored. After 2–3 yearsthe extent of the sclerotic changes stabilised and the rate of development reached 37–39 per cent in ears receiving only one VT, compared with 47–49 per cent in ears treated by more than one tube. The extent of the changes was no different whether or not one or more than one tube had been inserted. There was no overall evidence of resolution of sclerotic change with time.

Recurrent Otitis Media

Over the past several years the indications for adenoidectomy have become increasingly controversial. Attempts to justify the operation in recurrent otitis media by correlating cultures of the nasopharynx with cultures of middle ear fluid have been inconclusive. Using quantitative bacteriologic techniques, we have studied the levels of aerobic and anaerobic bacteria per gram of tissue in adenoids removed from 48 patients. In seven patients, adenoidectomy was performed for nasal obstruction alone, in 17 patients for chronic serous otitis media, and in 24 patients for recurrent suppurative and serous otitis media. Using the criterion that greater than 105 organisms/gm of tissue constitutes infection, we found that 83% (20) of patients in the third group had infected adenoids, as opposed to only 15% (4) in the first and second group combined. Adenoid size measured radiographically did not correlate with the presence of infection. When recurrent suppurative and serous otitis media are unresponsive to medical therapy including antibiotics and decongestants, adenoidectomy should be considered in addition to myringotomy and ventilation tubes.

OBJECTIVES: To evaluate prognostic factors related with cure rate, in pediatric patients with serous otitis media treated with laser-assisted tympanostomy without ventilation tubes, in a single institution. PATIENTS AND METHOD: The procedure was performed on 124 ears in 88 individuals, from 3 to 14 years old. External auditory canal anatomy, type of anesthesia, tympanic membrane and middle ear fluid characteristics, myringotomy size, and laser parameters, in relation to cure rate, were accordingly studied. RESULTS: The overall cure rate by ear at the end of the 2-month follow-up period was 54.83%, whereas 45.17% still suffered from otitis media. Multivariate statistical analysis demonstrated that the presence of a thick tympanic membrane is significantly correlated with pure outcome in children with serous otitis media, when laser-assisted tympanostomy without ventilation tubes is performed favoring a worse cure rate ( P < 0.023). Other parameters did not statistically correlate with the outcome. A 41% parental dissatisfaction rate was noticed. CONCLUSION: This study addresses selection bias for children with serous otitis media, candidates for laser-assisted tympanostomy. These are related to the duration of serous otitis media, the condition of middle ear mucosa, the thickness of the tympanic membrane, the type of anesthesia, and the cost of laser apparatus. There is likely to be a causal relationship between outcome and tympanic membrane appearance in children undergoing laser-assisted tympanostomy.

The aim of this study was to improve the accuracy and sensitivity of methods for ventilation tube patency evaluation after timpanostomy. New method of one-dimensional ultrasound middle ear sonography was developed. We studied ventilation tubes patency in 40 patients with otitis media with effusion, after timpanostomy. All patients tympanometry and one-dimensional ultrasound sonography was obtained at 4, 7th and one month after surgery. After timpanostomy in children with the otitis media with effusion, at 4 days after the surgery one-dimensional ultrasound sonography detected normal function of ventilation tubes in 75% patients. At the same time, according to tympanometry ventilation tube patency was recorded in 80% patients. On 7th  day after surgery one-dimensional ultrasound sonography detected normal function of ventilation tubes in 85% patients. According to tympanometry the 90% patients demonstrated normal ventilation tube function. One month after surgery one-dimensional ultrasound sonography detected normal function of ventilation tubes in 92.5% patients. At the same time, according to tympa nometry ventilation tube patency was recorded in 95% people. Calculation of ultrasound sonography sensitivity and specificity showed that the sensitivity of this process is 97.4%, specificity – 100%. The statistical significance of differences in ventilation tube patency assessment is not determined. Thus, we have proved one-dimensional ultrasound sonography the sensitive method for ventilation tubes patency validation. The method is simple, requires a bit of time for application, so it can be widely recommended for outpatient network.
