Histopathologic Findings

Osteoma of the external auditory canal is a rare benign tumor with an estimated incidence of 0.05% of total otologic surgeries. In most cases, an osteoma in the external auditory canal does not cause symptoms because the tumor grows slowly and does not occlude the ear canal. However, if the mass grows to occlude the external auditory canal, several symptoms can occur, including conductive hearing loss, aural fullness, and keratin debris accumulation. We present two cases of this rare tumor in a 23-year-old woman and a 19-year-old man. The mass was surgically excised at the level of the peduncle under local anesthesia with microscope assistance. The base of the excised mass was drilled with a diamond burr to remove all osseous lesions. Histopathologic findings showed spongiotic osteomas. In these cases, patients had symptoms of aural fullness, although the osteomas did not completely occlude the external auditory canal, and the symptoms improved after surgical excision without recurrence.

External auditory canal exostosis (EACE) is prone to occur in patients frequently exposed to cold water, which causes earwax impaction, recurrent otitis externa, and conductive hearing loss. The main treatment for symptomatic EACE is surgical excision. External auditory canal cholesteatoma (EACC) is a bone-destructive cystic mass caused by accumulation of plugs of desquamated keratin debris in the external auditory canal (EAC), which is also mainly treated with surgical removal. The main difficulties in the surgical removal of obstructive EACEs or EACCs are related to the adjacency of EAC skin, tympanic membrane, temporomandibular joint, and the blockage of the medial EAC landmarks during the operation. The piezoelectric device (PZD), which has long been used to cut bony structures in dental surgery, has clinical advantages here with regards to accurate exclusive bone cutting ability and minimal heat production. We report a series of cases that managed EAC lesions using PZD.

Eccrine syringofibroadenoma is a rare, benign tumor of eccrine ductal differentiation, typically presenting in the extremities. Herein we report a case of a 77-year-old man with pain in the lateral midfoot and the presence of an eccrine syringofibroadenoma lesion in the lateral heel. On surgical excision of the lesion, the foot pain promptly resolved, and at the most recent follow-up visit, the patient remained pain free.

Introduction. Despite modern radiological workup, surgeons can still be surprised by intraoperative findings or by the pathologist’s report.Materials & Methods. We describe the case of a 52-year-old male who was referred to our clinic with a single sided conductive hearing loss. He ultimately underwent middle ear exploration and excision of a middle ear tumour followed by second look and ossiculoplasty a year later.Results. Though preoperative CT and MRI scanning were suggestive of a congenital cholesteatoma, the pathologist’s report diagnosed a middle ear adenoma.Discussion. Middle ear glandular tumors are extremely rare and, despite numerous histological techniques, continue to defy satisfactory classification. Most surgeons advocate surgical excision though evidence of the tumour’s natural course and risk of recurrence is lacking.

Neuroendocrine adenoma of the middle ear (NAME) is a rare tumor. We report a case of NAME, the clinical and pathologic findings of which illustrate the biologic behavior of adenomatous tumors of the middle ear and their relationship with rare carcinoid tumors of the middle ear. A 29-year-old man presented with a history of recurrent otitis media, right conductive hearing loss, and aural fullness. The tumor was removed in its entirety. Otolaryngologists should be familiar with this unusual but important entity.

Tumors originating from ceruminous glands are rare lesions of the external auditory canal. The lack of specific clinical and radiological signs makes their diagnosis challenging. We report the case of an exceptionally rare benign tumor, a syringocystadenoma papilliferum (SCAP), in an atypical location in the bony segment of the external auditory canal with uncommon clinical signs. The special traits of the case included the following: the most lateral component of the tumor was macroscopically cystic and a granular myringitis with an obstructing keratin mass plug was observed behind the mass. The clinical, audiological, radiological, and histological characteristics of the neoplasm are consequently presented. Intraoperative diagnosis of the epidermal cyst was proposed. The final diagnosis of SCAP was determined only by histological analysis after the surgical excision. The educational aspects of the case are critically discussed.

The treatment of external auditory canal (EAC) stenoses often requires the prolonged use of a stent or splint. Traditional stents often occlude the EAC, resulting in a temporary conductive hearing loss. This case report describes a custom canal earmold with a large bore used as a stent in a patient with EAC stenosis. The customized earmold stent successfully prevented restenosis, while the large bore provided ventilation and improved hearing subjectively during the stenting phase. El tratamiento de la estenosis del conducto auditivo externo (EAC) a menudo requiere del uso prolongado de un stent o una férula. Los stents tradicionales a menudo ocluyen el EAC, provocando una hipoacusia conductiva temporal. Este reporte describe un caso un molde auditivo hecho a la medida con un agujero grande utilizado como stent en un paciente con estenosis del EAC. El stent de molde auditivo a la medida fue exitoso en prevenir la re-estenosis, mientras que el gran agujero aportó ventilación y mejoró subjetivamente la audición durante la fase de mantenimiento del stent.

Tympanic Membranes

Five cases of schneiderian-type mucosal papillomas arising in the middle ear space are reported. The patients were all women, ranging in age from 19 to 57 years (median, 31 years). Clinical complaints — unilateral conductive hearing loss, pain, or otorrhea — ranged from those lasting several months to recurrent problems spanning 20 years. All of the patients had a history of chronic otitis media predating the development of the papillomas; none of the patients had a history of sinonasal or nasopharyngeal schneiderian-type papillomas. Clinically, three patients had intact tympanic membranes, while the other two patients had perforated tympanic membranes through which a bulging polypoid mass was identified. Radiographic studies showed opacification of the middle ear space without evidence of osseous destruction. The intraoperative findings were of polypoid lesions filling the middle ear space, including involvement of the eustachian tube orifice. Histologically, the tumors were identical to sinonasal schneiderian papillomas. Immunohistochemical evaluation for human papillomavirus was negative. Surgical excision is the treatment of choice. In four of the patients, recurrent tumor was identified, necessitating additional surgery. In only one patient did the initial surgery result in complete ablation of the tumor. All patients are alive and free of recurrent disease over periods ranging from 6 months to 120 months (median, 84 months).

Cholesteatomas are found almost exclusively in the middle ear and mastoid. Occasionally this disease is seen in the external auditory canal. Cholesteatoma of the external auditory canal is a rare condition. Severe pain and profuse discharge associated with a normal eardrum and normal hearing are essential clinical features. In addition, we found facial paresis and conductive hearing loss in our case. Smaller cholesteatomas can be managed by frequent debridement in the office; larger lesions require surgical intervention. Surgery is successful in resolving otorrhea and relieving pain. In addition, our own experience has shown that surgery is successful in relieving facial paresis.
