Significance Statement: Primary middle ear inverted papilloma is an exceedingly rare finding posing a diagnostic challenge, as symptomatology often mimics common clinical entities like serous otitis media. Clinical and radiological findings are not specific, whilst high recurrence rates, local destruction, and potential malignant transformation constitute an overall demanding surgical challenge, requiring aggressive procedures. We report the case of a primary inverted papilloma of the middle ear, discussing diagnostic and therapeutic issues.

The middle ear fluids of seven patients with bilateral, and five patients with unilateral serous otitis media (SOM), were demonstrated to be microbiologically sterile when assessed for the presence of bacteria, mycoplasma, viruses, and fungi. The concentrations of immunoglobulins G, M, A, D, and lysozyme (muramidase) were determined in the serum and middle ear fluids. Lysozyme levels of middle ear aspirates were found to be elevated in SOM patients. The elevated levels of lysozyme in combination with the antibody-containing classes of immunoglobulins may explain the microbiologically sterile condition of the middle ear fluids of SOM patients. Also, the elevated lysozyme concentrations in middle ear fluids may indicate the previous presence of neutrophils and hence a previous inflammatory insult. The increased levels of IgA demonstrated in middle ear fluids may indicate local synthesis of secretory IgA by secretory cells of Eustachian tube and middle ear. The closed Eustachian tube, partial vacuum conditions and absence of a portal of exit for accumulated serous fluids are offered as a possible explanation for SOM.

Serous Otitis Media

In this issue of Pediatrics there is a report1 of a method by which abnormalities of the middle ear that affect mobility of the drum, and therefore hearing, may be assessed quantitatively. In brief, the technique, called tympanometry, measures the compliance of the ear drum and, by ascertaining compliance at different external pressures, estimates pressures in the middle ear. The value to pediatricians and their patients of a means by which ear drum compliance and middle ear pressure can be measured lies primarily in the diagnosis and management of serous otitis media. Clearly, the data presented in this report indicate that this technique will usually discriminate between ears with middle ear effusions and normal ears.

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.

Isoenzyme Patterns

Biochemical characteristics of middle ear effusions (MEE) should provide a better understanding of the etiopathogenesis of serous otitis media. In order to develop another parameter for the biochemical characterization of the MEE, lactate dehydrogenase (LDH) and LDH isoenzyme patterns in the serous middle ear effusion and serum from 20 patients with serous otitis media were compared. The LDH activity was measured by the usual spectrophotometric method. The isoenzyme patterns were compared on electropherograms using cellulose polyacetate strips. The LDH activity in MEE was significantly higher (P < 0.001) than it was in serum. Fractions of isoenzymes 1 and 2 were each smaller in MEE than in serum. Isoenzymes 4 and 5 have a significantly higher (P < 0.001) fraction in MEE than in serum. Since LDH is an intracellular enzyme and middle ear mucosa is reported to have high content of isoenzymes 4 and 5, the inflammatory changes in the middle ear mucosa which may release intracellular LDH, are suggested as the cause of both higher activity of LDH and the higher fractions of isoenzymes 4 and 5 in MEE than those in the serum.

AbstractObjective:We report an atypical case of ossicular necrosis affecting the incus, in the absence of any history of chronic serous otitis media. We also discuss the current theories of incus necrosis.Case report:A male patient presented with a history of right unilateral hearing loss and tinnitus. Audiometry confirmed right conductive deafness; tympanometry was normal bilaterally. He underwent a right exploratory tympanotomy, which revealed atypical erosion of the proximal long process of the incus. Middle-ear examination was otherwise normal, with a mobile stapes footplate. The redundant long process of the incus was excised and a partial ossicular replacement prosthesis was inserted, resulting in improved hearing.Conclusion:Ossicular pathologies most commonly affect the incus. The commonest defect is an absent lenticular and distal long process of the incus, which is most commonly associated with chronic otitis media. This is the first reported case of ossicular necrosis, particularly of the proximal long process of the incus, in the absence of chronic middle-ear pathology.

Review Of The Literature

Inverted papilloma (IP) with malignant transformation is rarely seen in the middle ear. Up to now, there have been 16 primary middle ear IPs reported in the English literature. Even though it is very rare in the middle ear, this pathology should be kept in mind for the differential diagnosis of middle ear masses. In this case, we report a 77-year-old female who had recurrent IP with malignant transformation and complication.
