Ceruminous adenoma is an extremely rare condition that arises in the external auditory canal. The right ear canal in a 32-year-old man was obstructed by a ceruminous adenoma mimicking otitis externa and its symptoms. The lesion was resected under microscopic view using a transcanal approach. There were no tumor-related symptoms postoperatively and he has been disease free for 1 year after surgery.

The Relationship

The external auditory canal is not only a part of the external ear, but also an integral part of the human auditory system, which conducts and amplifies the sound wave. In the field of otosurgery, it is often the priority access to the tympanic cavity, and therefore it is necessary to clearly understand the features of its anatomy. The dimensions and anatomy of the external auditory canal are extremely variable: the length is 2–3,5 cm, the diameter ranges from 5-9 mm, it is somewhat curved in the horizontal and frontal planes and consists of a membranous cartilaginous part and a bony part, between which there is the most the bottleneck – the isthmus. The ear canal is covered with skin, the thickness and structure of which depends on the section of the ear canal. The membranous cartilaginous section contains sebaceous and sulfur glands. Studies identify several forms of the bony part of the ear canal: conical, hourglass-shaped, ovoid, reverse conical, and cylindrical. The endoscopic scale (CES) for the visibility of the tympanic membrane was also proposed for the convenience of assessment. It has been suggested that the shape of the external auditory canal is an etiological factor in chronic otitis externa. Unambiguous interpretations of the relationship between ear diseases and the shape of the external auditory canal have not yet been obtained, but modern developments tend to consider its importance in the development of ear diseases. Clinical observations show that certain anatomical forms of it may be involved in the pathogenesis of chronic inflammation, since they interfere with proper self-cleaning.

The tumors derived of the ceruminous gland in the external auditory canal are rare. Here, we report a case of a ceruminous adenoma (apocrine adenoma) with refractory chronic inflammation in the external auditory canal. A 46-year-old man presented with otorrhea, itching, and a foreign body sensation in his right ear. A soft reddish protruding lesion was revealed at the posterosuperior portion of the entry to the right external auditory canal by otoscopy. The skin lesion was endaurally resected; histopathology showed luminal structures in the middle to deep layer of the epidermis and inflammatory granulation below pseudoepitheliomatous hyperplasia. The walls of the luminal structures consisted of inner luminal secretory cells featuring apical decapitation secretion and outer myoepithelial cells. The patient was diagnosed with an apocrine adenoma. Three years after surgery, there has been no evidence of recurrence. Complete resection, including the deep layer of the epidermis, is necessary.

AbstractA 69-year-old man presented with a three-month history of otalgia and tenderness of the right ear and a one-week history of a painful right parotid swelling. Examination revealed granulation tissue in the right ear canal with normal looking tympanic membranes and a parotid abscess. Repeated biopsies from the ear canal and parotid showed non-specific inflammation. Repeated cultures from both areas grew Ps. aeruginosa. The patient's condition improved following three weeks of intensive treatment for malignant otitis externa only to relapse five weeks after the end of treatment. He received a second course, only to improve temporarily. He developed a right facial nerve palsy five weeks after he was first seen, followed four months later by palsies of all cranial nerves except the olfactory, before dying, seven months after his first appointment.The radiological, histological and post-mortem findings are discussed.

We report a rare case of isolated malleus dislocation into the external auditory canal with lateralized intact tympanic membrane following a head trauma. The patient was a 63-year-old woman who presented at the outpatient department of our institute with hearing loss of 10 years’ duration after a bicycle accident. During physical examination of the patient, total dislocation of the malleus-like bony structure into the external auditory canal on the right side was observed. In the computed tomography scan, an isolated malleus dislocation with intact incus-stapes articulation was identified. The patient was successfully treated with endoscopic exploratory tympanotomy and partial ossicular replacement prosthesis. The isolated malleus dislocation can rarely occur after trauma. A careful diagnostic step through history, physical examination, and temporal bone computed tomography scan are needed to confirm this rare condition.

Pseudomonas is a Gram-negative bacterium frequently recovered from environmental sources, particularly an aquatic environment. Epidemics of skin rash,1 otitis externa,2 isolated cases of urinary tract infections,3 and pneumonia4 have been associated with whirlpools contaminated by Pseudomonas aeruginosa. This report describes P aeruginosa otitis externa in an infant associated with a contaminated infant bath sponge. CASE REPORT K.E., a 3-month-old, first born, healthy girl was seen for drainage from the left ear. She was listless and febrile and had a moderate amount of whitish drainage from the left ear canal. There was no discharge from the right ear canal, but on examination there was right otitis media.

Follicular Cysts

An 11-year-old, 18-kg, neutered male standard schnauzer was presented for evaluation of recurrent otitis externa with para-aural swelling and fistulation of the right external ear canal of 6 months’ duration. Otoscopic examination was impossible because of the severe stenosis of the ear canal. Right para-aural ultrasound examination and ultrasound-guided fine-needle aspiration of a mass-like lesion were performed. Cytology was suggestive of a follicular cyst. Magnetic resonance imaging revealed severe ear canal stenosis with a heterogeneous mass in the horizontal portion of the ear canal and associated otitis media. Total ear canal ablation with lateral bulla osteotomy was performed. Histopathological diagnosis was chronic otitis externa associated with multiple follicular cysts confined to the ear canal. Surgical treatment proved curative. This is the first report of multiple follicular cysts originating from the ear canal in a dog.

Acute otitis externa (AOE) is an infection of the external auditory canal, the auricle, and the outer surface of the tympanic membrane. Although AOE is one of the most common otologic conditions encountered in pediatric population, it is known to primarily affect children older than 2 years. We report a case of AOE caused byStaphylococcus aureusin a 23-day-old neonate. A 23-day-old female infant presented to our neonatology clinic with irritability and discharge from the right ear. There were yellow otorrhea, mild erythema, and edema of right external ear canal. There was no sign of otitis media on otoscopy. The results of laboratory tests were insignificant. The discharge culture grew colonies of methicillin-sensitiveStaphylococcus aureus. After 48 hours of treatment with intravenous cloxacillin, significant improvement was observed. The present case highlights an unusual presentation of staphylococcal infection in a neonate. This is the first case of methicillin-sensitiveStaphylococcus aureusotitis externa in an immunocompetent newborn.

Variable pH values for skin have been reported in the literature, all within the acidic range, varying from 4.0 up to 7. 0. The origin of the acidic pH remains conjectural, and several factors have been incriminated with this role, such as eccrine and sebaceous secretions as well as proton pumps. Keeping low levels of pH prevents microbial dispersal as well as multiplication. The skin in the external auditory canal is also covered with this acidic mantle with antimicrobial value. Changes of pH in the external ear can lead to acute otitis externa. This condition is defined by the inflammation and infection of the cutaneous and subcutaneous tissues of the external auditory canal. 10% of the world�s population may suffer from acute otitis externa at least once in their lifetime. This paper aims to consolidate the relevance of an acidic pH in the healthy external ear and its relation to the pathogenesis and treatment of otitis externa through a prospective and interventional clinical study on 80 patients who presented to the outpatient department at Prof. Dr D. Hociota ENT Institute in Buch
