Surgery for recurrent and residual cholesteatoma.

One hundred twelve patients (116 ears) were treated for recurrent and residual cholesteatoma. A retrospective review revealed that 66% had undergone canal wall down mastoidectomy at the previous surgery. The surgical procedure at revision was selected on the basis of an intraoperative assessment of the extent of disease, and clinical prediction of eustachian tube function. The average period of follow-up was 3.4 years. Revision surgery was successful in providing the patient with a safe, dry ear in 105 (91%) of 116 cases. Surgical principles and hearing results are presented.

Management of labyrinthine fistulas caused by cholesteatoma.

The surgical management of labyrinthine fistulas caused by cholesteatoma remains controversial. Forty cases (41 ears) of labyrinthine fistulas were reviewed. This represented 10% of our total series of cholesteatomas in adults and children (426 ears). Clinical presentation, extent of disease, results of fistula testing and audiometric studies, and radiographic findings were analyzed. A canal wall-down procedure was performed in all but one patient. Generally an attempt was made to completely remove the cholesteatoma, to graft the fistulous area, and to reconstruct the middle ear mechanism in one stage. The matrix was preserved in patients with large fistulas where the involved ear was the only hearing one, when the matrix was adherent to the underlying optic duct, and in selected elderly persons. Long-term followup did not reveal a significant difference in hearing, degree of vertigo, or incidence of recidivism when those patients in whom the matrix was removed were compared with those in whom the matrix was preserved. The importance of recognizing the presence of a labyrinthine fistula preoperatively is stressed, along with the need to be prepared for an unexpected fistula. Operative management is described.

Assessment of clinical skills using videotapes of the complete medical interview and physical examination.

Complete medical interviews and physical exams were performed on two stimulated patients by a class of medicine interns. These interviews and examinations were videotaped and were then scored using a rating scale developed by the authors. This system of videotaping and rating complete interviews and physical examinations is called the The Northwestern Evaluation & Training System (NETS). Selected findings are presented and discussed. It is shown how the NETS can be used for educational feedback to the individual student and for quality assurance feedback to training programs regarding the effectiveness of their instruction in interview and physical examination skills.

The large vestibular aqueduct syndrome in children. A review of 12 cases and the description of a new clinical entity.

The large vestibular aqueduct as an isolated anomaly of the temporal bone has been previously identified radiologically, and its association with sensory neural hearing loss has been recognized. It has not, however, been defined as a distinct clinical entity in children. We studied 12 children, ages 3 to 9 years, with downward-fluctuating progressive high-frequency neurosensory hearing losses whose symptoms were thought to be related to the isolated enlargement of the vestibular aqueduct identified by high-resolution computed tomographic scanning. Previously it had been assumed that a large vestibular aqueduct is a temporal bone dysplasia that is a variant of the Mondini type of deformity and that the associated hearing loss is congenital in nature. Our clinical observations, however, indicate that the hearing loss in children with an isolated enlargement of the vestibular aqueduct is acquired during childhood. The natural history of this progressive deafness is reviewed, and a pathophysiologic hypothesis is presented.

Acquired cholesteatoma in the pediatric age group.

Successful treatment of cholesteatoma in children is based on the same principles of therapy used in adults. A clinical profile of children with acquired cholesteatoma is compared with that of adults. Issues related to aggressiveness of disease, pathophysiology, diagnostic problems, and treatment approaches are discussed.

Surgical techniques and recidivism in cholesteatoma.

Cholesteatoma is a difficult disease to treat as demonstrated by the relatively high recidivism rate attained by the best of surgeons. The concept of recidivism encompasses all reoccurrence of the disease, regardless of the theorized origins. This is a term that should be accepted so that some uniformity may be introduced into the evaluation of this disease. A standard reporting format that includes the extent of the disease, the eustachian tube function, the integrity of the ossicles, and a uniform description of the surgical procedure would enhance future evaluations of this disease. The future of otology still lies in finding new ways to eradicate this disease and to avoid recidivism.

Management of congenital pediatric cholesteatomas.

During the past 10 years discrete middle ear congenital cholesteatomas have been detected with greater frequency in young children. The increased recognition of this condition is probably related to the pediatricians' greater awareness of this defect, their improved facility with pneumatic otoscopy, and effective audiometric and tympanometric screening procedures. This early detection while the lesions are small and localized facilitates their surgical removal. Clinically, it would appear that congenital cholesteatomas can be subdivided into two categories according to their anatomic locations. The anterior lesions present as an isolated pearl that arise from an area on the anterior surface of the malleus, are usually associated with normal hearing, and have pneumatized mastoids. The posterior lesions do not seem to originate from a clearly defined anatomic area, have a higher incidence of sclerotic mastoids, and erode the ossicular chain commonly producing a hearing loss. The anterior middle ear cholesteatoma probably arises from a persistent epidermoid formation, a structure that normally is present during fetal development of involutes by the 33rd week of gestation. The origin of cholesteatomas arising in the posterior middle ear space remains more controversial.

Otitis media.

Otitis media is a disease involving the inflammation and infection of the middle ear. Despite modern medical therapy, its widespread incidence in all age groups makes it one of the most common illnesses seen by physicians. The advent of a wide range of antibiotics has helped to decrease the number of complications resulting from the disease. Nevertheless, the large number of missed school and work days and the hearing losses and related problems that accompany otitis media make it a perpetual menace to public health.

Fibrous dysplasia involving the temporal bone: report of three new cases.

Monostotic fibrous dysplasia, an unusual disease that can involve the temporal bone, will frequently cause an acquired stenosis of the external auditory canal. Three patients with this disorder who presented with occluded canals are described. Two individuals developed external canal cholesteatomas medial to the obstruction, one of whom eventually developed a postauricular abscess and infected draining sinus. The third patient presented with a restenosis nine months following canalplasty. The cases reported illustrate three surgical criteria necessary to manage these unusual cases successfully: removal of sufficient diseased bone to create a patulous canal; resurfacing denuded bony areas with thin split-thickness skin grafts to prevent soft tissue contractions; an adequate meatoplasty. Postoperatively, the reconstructed canals have remained patent and stable during follow-up periods ranging from one to four years. Clinical, radiographic, and pathologic features of fibrous dysplasia are discussed, the differential diagnosis is presented, and the relevant literature is reviewed.

Verrucous carcinoma of the temporal bone.

Verrucous carcinoma, a familiar lesion of the oral cavity and larynx, is distinctly rare in the ear. We report five cases of verrucous carcinoma of the temporal bone, each of which fulfills Ackerman's histologic and biologic criteria. Only three cases of verrucous carcinoma of the ear have been previously reported. Most cases of verrucous cancers of the head and neck demonstrate a lack of nodal involvement, relatively slow growth potential, local invasiveness, and responsiveness to surgical treatment. In our five cases of verrucous carcinoma of the temporal bone, three had a biologic behavior similar to other verrucous tumors, while two cases were unusually aggressive. Three patients were treated surgically and had favorable outcomes, while the remaining two were treated with combination therapy. These cases highlight the difficulty in diagnosis and treatment as well as the lack of understanding of the biologic behavior of this rare otologic entity.

Cholesteatoma in the pediatric age group.

The diagnosis and management of cholesteatoma in children remains controversial. In the past 15 years, the senior author (S.C.P.) has treated 320 patients with cholesteatoma. Patients 18 years and younger composed 40% (125) of the overall group and are the basis for this report. The patient data were compiled using the history, physical examination, audiograms, radiographs, patient questionnaires, surgical findings, and postoperative observations. The surgical treatment selected was determined by the extent of disease, the configuration of the mastoid, and a clinical assessment of eustachian tube function. A middle ear tympanotomy approach was used in 17% of the patients, a canal wall up procedure in 31%, and a canal wall down procedure in 52.3%. The average clinical follow-up was 3.9 years, with the range being from 3 months to 13.5 years. Hearing was maintained or slightly improved in a majority of cases. Residual disease occurred in 8% of patients, and recurrent disease in only 3%.
