Patients with chronic otitis media that did not respond to conventional treatment were studied for the types and incidence of complications from the use of large-bore tubes inserted into their ears. The most common complication was otorrhea (41%, 50 of 123 ears). Permanent perforation occurred in 25% (17/68 ears). Use of large-bore tubes proved effective and continues to be indicated in certain conditions of chronic otitis media that are refractory to other forms of treatment.

Ear Effusion

Otitis media with effusion can be successfully treated without the use of middle ear ventilation tubes. Middle ear inflation will, if performed properly, empty most ears as effectively as direct suction through a myringotomy incision. Over 12,000 patients with middle ear effusion have responded to conservative treatment which includes medical management aided by middle ear inflations using a modification of the classic politzerization technique. The technique of controlled middle ear inflation is described and the proper medical management discussed. The avoidance of oral decongestants is stressed as is the proper diagnosis and treatment of the etiological factors causing the formation of the fluid.

Background: Middle ear ventilation and the drainage of secretions are the basic functions of the eustachian tube. Eustachian tube (ET) dysfunction can lead to otitis media. Multiple causes of ET dysfunction exist; ET obstruction is one of them. Osseous obliteration of ET is quite rare. In the literature, there are two cases of solitary osteoma and a case of hamartoma with an osseous content in the ET. Herein, this report describes the case of a patient with multiple osseous lesions consistent with osteomas in the ET, causing ipsilateral otitis media with CT findings. Case Report: A 53-year-old woman presented with left-sided intermittent otalgia and otorrhea. Temporal bone computed tomography showed opacification of middle ear consistent with otitis media and nearly complete blockage of the left ET lumen with multiple osseous lesions wall probably consistent with osteomas on the left side. Conclusion: There are limited data about the radiological features of ET osteoma due to its rare occurrence. Radiographically, external ear osteoma generally appears as a single pedunculated hyperdense mass on CT scan originating from the tympanosquamous or tympanomastoid suture line and extending into the auditory canal with otherwise preserved canal dimensions. Considering this information, osseous lesions arising from ET bone wall and extending into the lumen in the present case were considered as osteomas. Especially in the case of unilateral chronic otitis media, ET should not remain a neglected anatomical area.

Middle Ear Ventilation

Introduction: Balloon dilation of the cartilaginous segment of the Eustachian tube has emerged as a means to directly augment tubal dilatory function, and this has been applied as a potential treatment for otitis media with effusion (OME). Although results of clinical studies involving this modality appear promising, there are still a moderate number of ears affected by OME that do not respond. The purpose of this study was to investigate the status of mucosa of the Eustachian tube at the middle ear orifice in OME as it may relate to some cases of tuboplasty failure. Methods: Twenty-three temporal bone specimens with OME were identified within an institutional archived collection. Each specimen was inspected for the presence of a fixed obstruction at the level of the Eustachian tube orifice at the protympanum. In addition, the mucosa at the tubal orifice was graded on a 4-point scale. Results: Overall, 3 cases (13%) were normal (Grade 1), 6 cases (26%) were mildly thickened (Grade 2), 11 (48%) were severely thickened (Grade 3), and 3 (13%) were severely thickened with polypoid degeneration (Grade 4). A single case was noted to have a complete fixed obstruction in the form of a mucosal web. Conclusion: In ears affected by OME, the mucosa of the Eustachian tubal orifice at the middle ear is most often severely thickened. Normal mucosa, mucosa with severe polypoid changes, or a complete fixed obstruction are possible but uncommon. The majority of specimens studied had sufficiently diseased mucosa to raise questions regarding whether thickened mucosa in the tubal orifice may act as a barrier to middle ear ventilation that would not be directly addressed by cartilaginous Eustachian tube balloon dilation.

Ventilation Tubes

Surgical methods of treating otitis media and its sequelae are discussed, according to the classification of otitis media presented in an earlier report Surgical management of otitis media with effusion and recurrent purulent otitis media includes myringotomy and use of ventilation tubes. Occasionally, otitis media with effusion will lead to structural and other pathologic changes in the middle ear, and conservative treatments such as use of medication or tubes will not suffice. Indications and methods for exploratory tympanotomy and reconstruction of the middle ear are discussed. In such instances, tympanoplasty can be used to the patient's benefit Chronic otitis media with mastoiditis, defined by the presence of intractable pathologic tissue, generally requires surgical correction. Classic methods include simple mastoidectomy, modified radical (Bondy) mastoidectomy, and radical mastoidectomy. Current classifications of procedures would also include closed-cavity tympanomastoidectomy, open-cavity tympanomastoidectomy, and intact-bridge tyrnpanomastoidectomy (a combined approach). The diagnostic and surgical approach to silent or subclinical otitis media is discussed. Diagnosis and treatment of sequelae of otitis media, including sequelae in the middle ear and, less commonly, in the inner ear, are discussed.

AbstractThe fate of 32 Per-Lee ventilation tubes inserted by a single surgeon for secretory otitis media in children and adults is analysed over a 15-year period. There were no extrusions and 25 tubes were still functional at the time of the survey. The total ventilation time achieved by the 32 tubes was over 157 years. Seven tubes were removed on account of either obstruction or infection. Spontaneous healing of the tympanic membrane was uncertain following removal of the tube and a considerable degree of scarring was inevitable. Hearing improvement occurred while the tube was functioning and there were no cases of hearing deterioration. It is concluded that the Per-Lee tube is a suitable prosthesis for long-term middle-ear ventilation.

Background: The middle ear cavity is ventilated through the aditus ad antrum. Aditus blockage contributes to the pathology of otitis media. Objective: To determine the normal values of the aditus ad antrum diameter on computed tomography and to investigate its relationship with chronic otitis media and related pathologies (tympanosclerosis and myringosclerosis). Methods: The temporal CT images of 162 individuals were evaluated retrospectively. In the axial sections, the inner diameter of the aditus was measured at the narrowest point at the cortex. The differences in diameter were compared between diseased and healthy ears. Results: In healthy individuals, the diameter was narrower in women. There was no difference between the right and left ears in healthy subjects. No correlation was found between age and diameter. In male patients with myringosclerosis, the diameter was slightly narrower on both sides but more marked on the left. In female patients with myringosclerosis, the diameter in both ears was slightly narrower. In cases of otitis media and tympanosclerosis, the diameter was less than that of healthy individuals, despite the lack of statistically significant result in all cases. Conclusion: The aditus ad antrum was narrower in diseased ears, indicating that a blocked aditus may contribute to the development of otitis media, as well as mucosal diseases.

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.
