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.

Aims. Hidrocystomas are benign cystic growths of the apocrine and eccrine sweat glands. These cystic lesions have been well documented on the face, head, and neck, but rarely in the external auditory canal. Presentation of Case. A 67-year-old woman presented with a bluish cystic mass partially occluding the external auditory canal and interfering with hearing aid use. Lesion was excised completely via a transcanal endoscopic approach with excellent cosmetic results, no canal stenosis, and no recurrence at 1-year follow-up. Discussion. We present a rare eccrine hidrocystoma of the external auditory canal and successful excision of this benign lesion. We describe the surgical management using a transcanal endoscopic approach and follow-up results. An eccrine gland cyst that presents as a mass occluding the external auditory canal is quite rare. There are only a few such cases reported in the literature. These masses can be mistaken for basal cell carcinomas or cholesterol granulomas but can be easily differentiated using histopathology. Conclusion. Eccrine hidrocystoma is a cystic lesion of sweat glands, rarely found in the external auditory canal. A characteristic bluish hue aids in diagnosis and surgical excision using ear endoscopy provides excellent control.

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.

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 Cholesteatoma

Transcanal endoscopic ear surgery is a minimally invasive procedure that allows a clear visualization of the middle ear. Recently, indications for endoscopic surgery have been expanding. We performed combined underwater endoscopic and microscopic surgery for external auditory canal cholesteatoma, the computer tomography of which indicates the possibility of cholesteatoma not only in the canal wall but also in the mastoid. The 30° endoscope and underwater technique makes the surgical view clear, and we could remove the cholesteatoma without canalplasty. To the best of our knowledge, no case of external auditory canal cholesteatoma treated with underwater endoscopic and microscopic surgery has been previously reported. This case indicates that the procedure could be a good indication for external auditory canal cholesteatoma.

Reactive Process

Auditory exostoses are bone masses located in the external auditory canal. Currently, most researchers agree that the environment (especially water temperature, but also atmospheric temperature and wind action) plays a pivotal role in the development of exostosis. Exostoses are a condition in which the external auditory canal becomes stenotic secondary to hyperplastic bone formation. Also known as ‘‘surfer’s ear,’’ exostoses are thought to be a reactive process from repeated stimulation by cold water because it occurs commonly in populations such as beach lifeguards and surfers. Exostoses are usually asymptomatic and discovered on routine otoscopy. Rarely, exostoses become sufficiently obstructive to impair hearing or cause recurrent otitis externa. Exostoses are almost always bilateral, symmetric, and occurring in the medial portion of the external auditory canal. Tthe authors report a case of bilateral external auditory canal exostoses in an adult male treated with surgical excision.  DOI: http://dx.doi.org/10.3329/bjo.v18i1.10428  Bangladesh J Otorhinolaryngol 2012; 18(1): 91-95

Introduction: Totally endoscopic ear surgery (TEES) is defined as exclusive application of endoscope transcanally in otologic surgery. This study is aimed to highlight indications and ear pathologies for TEES. In addition, intraoperative, early postoperative and delayed postoperative complications of TEES will be also described in this study. Methodology: This is a retrospective study of TEES performed by a single experienced and trained otologist in endoscopic ear surgery in a single institution between 1 July 2014 and 31 June 2018. A total of 43 patients were recruited in this study. Sociodemographic information, indications for TEES, ear pathologies, type of surgery performed and complications of TEES were analyzed. Results: The indications for TEES comprised middle ear lesion (65.1%), followed by second look surgery (14.0%), external auditory canal lesion (11.6%) and internal acoustic meatus lesion and surgery for conductive hearing loss which were 4.7%. Various external auditory canal pathologies encountered for TEES were ear canal osteoma (4.7%), acquired ear canal stenosis (2.3%) and tumor (4.7%). Regarding middle ear pathologies, limited atticoantral cholesteatoma accounted for most of the cases, 46.5%. Other middle ear lesions included adhesive otitis media (14.0%), recurrent cholesteatoma (14.0%), tumor (4.7%), otosclerosis (2.3%) and ossicular discontinuity (2.3%). Internal acoustic meatus lesion constituted 4.7% of cases. Some 4.7% of cases developed intraoperative complications, while early and delayed complications were 7.0%. Conclusion: TEES is a feasible surgical technique for diverse ear pathologies in the otologic specialty. It is also proven to be safe with good surgical outcomes.

AbstractBackground:Lesions arising in the external auditory canal that require surgical excision are uncommon. They are associated with a range of pathologies, including bony abnormalities, infections, benign and malignant neoplasms, and epithelial disorders.Methods:This paper describes a 10-year personal case series of external auditory canal lesions with chart, imaging and histopathology review.Results:In total, 48 lesions required surgical management, consisting of: 13 bony lesions; 14 infective lesions; 14 neoplasms with 11 histological types (including ceruminous adenoma and the extremely rare cavernous haemangioma); 3 epithelial abnormalities; and 4 other benign lesions. The surgical management is described.Conclusion:This study emphasises the diagnostic differences between exostoses and osteomas, and between external auditory canal cholesteatoma and keratosis obturans. It also discusses the management of aural polyps, and highlights the need to excise external auditory canal masses for histology in order to guide subsequent treatment.
