Spontaneous posterior wall external canal cholesteatoma.

A 44-year-old woman with a history negative for trauma, inflammation, surgery, or radiotherapy of the head or neck was referred for cerumen removal. Following the cerumen removal, a dehiscence of the posterior wall of the bony canal with squamous debris suggestive of external canal cholesteatoma was ob-served (figure).This is a rare condition usually involving the inferior auditory canal

Endoscopic Ear Surgery in Children

Endoscopic assistance is gradually gaining recognition in otology not only for office examinations but also during surgery. The first endoscopic surgical procedure that was started in our institution was endoscopic ventilation tube placement to manage children with stenotic and curved canals. Following this, endoscopy was used in all type I tympanoplasty and stage I cholesteatoma removals with the advantage of avoiding a postauricular or endaural approach. The last application of endoscopic assistance was to better visualize round window and scala tympani via posterior tympanotomy during cochlear implantation. There are several advantages in using endoscopes: the wide view obtained and the possibility to observe areas behind the angle with less invasiveness and its excellent resolution, in addition to its intense light and higher magnification that facilitates teaching and tutoring. The limits of endoscopic surgery are that one hand is always needed to hold the endoscope and the lack of a third dimension. Until miniaturization of 3D systems allow the possibility to work in the narrow external ear canal, in order to overcome the limitation that one hand is dedicated to the endoscope, we will describe the use of an endoscope holder in otologic procedures

Smell and taste alterations in Covid-19: a cross-sectional analysis of different cohorts

Olfactory (OD) and gustatory (GD) dysfunction have been proven to be a typical symptom of SARS-CoV-2 infection. However, their prevalence in different patient populations still needs to be clarified

Management and prognostic factors of recurrent pleomorphic adenoma of the parotid gland: personal experience and review of the literature

The aim of this study was to investigate the management and prognostic determinants of recurrent pleomorphic adenoma (RPA). A retrospective analysis was performed to examine the clinical features, the prevalence of surgical complications, and new recurrences of RPA. Tumor recurrence rate was estimated by the Kaplan–Meier method, and the prognostic value of some of the variables was tested by univariate analysis using the log rank test. The study focused on 33 patients, 18 female (54.5%) and 15 male (45.5%), aged 12–71 years (median 41). A total or extended total parotidectomy was performed in 16 cases (48.5%), a superficial parotidectomy in 10 cases (30.3%), and a local excision in 7 cases (21.2%). In ten patients (30.3%), a branch or the trunk of the facial nerve was deliberately sacrificed. Major complications included one unexpected definitive paralysis of the marginal mandibular branch of the facial nerve and 14 cases of Frey syndrome. Follow-up varied from 2 to 25 years (median 10.5 years), and there were 11 new recurrences (33.3%) within a period varying from 1 to 16 years (median 6 years). The estimated tumor recurrence rates were 14.1 ± 6.6% at 5 years, 31.4 ± 9.4% at 10 years, 43.0 ± 10.8% at 15 years, and 57.2 ± 14.8% at 20 years. Presence of a multinodular lesion and the type of intervention performed were significantly associated with a higher probability of recurrence. RPAs are prone to new recurrences, especially when multinodular and treated with a local excision. Surgical treatment should include facial nerve resection in selected cases. Follow-up for the patient’s lifetime is warranted

Long-Term Surgical Results of Cortical Mastoid Bone Osteomas

Background: Though osteomas can commonly arise in the cranial bones, an extra canalicular mastoid bone location is a rare entity with less than 200 cases described to date. We present three cases of cortical mastoid bone osteomas and compare them with cases presented in the literature. Methods: In this study, we used a retrospective chart analysis. Results: All three patients presented after years of progressively increasing postauricular swelling without symptoms. Temporal bone non-contrast CT allowed accurate preoperative diagnosis. Surgical treatment was performed for cosmetic issues with minimal postoperative morbidity. Complete excision was achieved in all cases, and to date, there is no evidence of recurrence. Conclusions: Mastoid osteomas are rare benign slow-growing tumors. They usually present as a painless cosmetic disfigurement and are otherwise asymptomatic. Surgical excision is the treatment of choice when they cause esthetic discomfort or are symptomatic. Recurrences are infrequently reported

Osteoneogenesis at the Round Window: A Possible Cause of Cochlear Implant Failure?

Surgery for cochlear implant is a traumatic procedure, with inflammatory responses leading to immediate and delayed intracochlear changes, resulting in newly formed fibrous and bony tissue. This newly formed tissue is thought to affect speech perception with cochlear implants and can also play a role in causing device malfunctioning and soft failures. We present a case of left cochlear implant explantation and reimplantation in a 15-year-old girl, who experienced deterioration of speech perception and device failure associated with osteoneogenesis of the round window, which could represent a cause of cochlear implant failure. To avoid surgical trauma of the cochlear lateral wall, enlarged round window insertion rather than a cochleostomy, soft surgical techniques, and the application of steroids are all important issues to prevent new tissue formation, although special attention should also be given to the trauma of round window borders
