Three hundred and twenty-six patients with diagnoses of serous otitis media—or mucold otitis medid—were reviewed for the presence or absence of middle ear cilia activity. This study strongly suggests that if active cilia can be observed, ventilating tubes are not needed. This easily observed activity in the anterior-inferior quadrant offers the otolaryngologist an accurate tool for determination of the future health of the middle ear.

OBJECTIVE: To determine whether tympanostomy tube (TT) inner diameter or shaft length impacts the rate of mucoid plug clearance. STUDY DESIGN AND SETTING: Ex vivo model. Silicone TTs with different inner-diameters (ID) and shaft-length (SL) pairings (1.14 mm ID × 12 mm SL versus 1.14 mm ID × 1 mm SL; 1.14 mm ID × 4.8 mm SL versus 1.32 mm ID × 4.8 mm SL) were plugged with middle-ear mucus (n = 15 per group) and placed in a model ear chamber. Ofloxacin otic solution was instilled into the chamber to cover the plugged TT, and the time to clearance of each plug was recorded. RESULTS: TTs with larger IDs ( P = 0.019) and greater SLs ( P = 0.033) cleared plugs more rapidly. However, the difference in the percentage of tubes that unplugged was not significant ( P = 0.151). CONCLUSIONS: Rate of ex vivo TT plug clearance may be altered by changing TT ID and SL.

Chinchillas with unilateral tympanostomy tubes in place underwent palate-clefting in an effort to determine the histologic and bacteriologic effects of using tympanostomy tubes in the treatment of otitis media. The tympanostomy tube appeared to almost totally eliminate the occurrence of middle ear effusion but had much less, if any, effect on eliminating the middle ear inflammation which occurs in the clefted chinchilla.

ABSTRACT Tympanostomy tube (TT) insertion for ventilation of the middle ear is one of most commonly performed procedures in the United States. Indications for tube insertion include otitis media with effusion, recurrent acute otitis media, hearing loss caused by middle ear effusion and persistent acute otitis media. In general, TTs are divided into two categories, short-term tubes and long-term tubes. Depending on the indications for tube placement and surgeon experience with the TT, different tubes can be used. A myriad of tubes have been created since their first documented use in 1845 in attempts to provide better middle ear ventilation, improve ease of placement and prevent complications, such as post-tube otorrhea, persistent perforation and tube occlusion. In order for a tube to be effective, it should be biocompatible with the middle ear to minimize a foreign body reaction. Teflon and silicone remain two of the most commonly used materials in TTs. In addition, the tube design also plays a role for insertion and retention times of TTs. Lastly, TTs can also be coated with various substances, such as silver-oxide, phosphorylcholine and more recently, antibiotics and albumin, in order to prevent biofilm formation and decrease the rate of post-TT otorrhea. Persistent middle ear effusion affects many children each year and can impact their quality of life as well as hearing and language development. With nearly 1 out of every 15 children by the age of 3 years receiving TTs, it is imperative that the right tube be chosen to facilitate optimal ventilation of the middle ear while minimizing complications.

A pilot study was conducted to evaluate the efficacy of a membrane ventilating tube as a Eustachian tube prosthesis in 20 patients with otitis media. The design was based partly on assumptions since many of the physiological parameters required to calculate the gas transport processes have not been previously reported. An elementary gas transport model with assumed partial pressures of gases was developed. A semipermeable membrane covering a tympanostomy tube was fashioned and used to ventilate the middle ear cavity. From this preliminary investigation, the device successfully maintained atmospheric pressures in the tympanum, compensated for Eustachian tube malfunction, prevented otorrhea and recurrence of middle ear effusions.

Background/Aim. Secretory otitis media (SOM) is a chronic, nonpurulent inflammation of the middle ear, characterized by a long-term presence of liquids of different density in the middle ear for at least three consecutive months, different degrees of hearing loss and the absence of perforation of the eardrum. The aim of this study was to estimate the early postoperative complications after insertion of tympanostomy tube (TT) in children with secretory otitis media (SOM) in an 18-month period after TT insertion. Methods. This retrospective study included children with SOM (n = 478), aged from 2.5 to 16 years, operated from 2000 to 2009. During these ten years 365 children had TT in both ears, 131 children had TT in one ear and 55 children were operated two or more times. Totally 843 ears were operated on. Date were obtained by regular fallow up in Out-patient clinic concerning symptoms reported by children and parents, otomicroscopy findings and hearing measurements (audiometry and tympanometry). Results. Transient otorrhea was the most common early postoperative complication (16.5%), then obstruction (9.5%), premature extrusion of TT (3.9%), chronic otorrhea (3.1%), granulation tissue (1.1%) and medial displacement (0.5%). According to our experience gold and silicone TT were shown less successful than others. The incidence of premature extrusion of TT was significantly higher with gold TT, comparing to others (6/33, 18%; p < 0.001). We also found significantly more frequent medial displacement with silicone TT than with other ones (2/4, 50%; p < 0.001). Conclusion. There are many early postoperative complications of TT insertion, but they depend on the meticulous surgery techniques, regular postoperative examinations and the type of TT. The type of TT should be determined according to own experience.
