Characteristics of 419 patients with acquired middle ear cholesteatoma

Brazilian Journal of Otorhinolaryngology (2016)

Letícia Petersen Schmidt Rosito Maurício Noschang Lopes da Silva Fábio André Selaimen Yuri Petermann Jung Marcos Guilherme Tibes Pauletti

Cholesteatoma is a destructive lesion that can result in life-threatening complications. Typically, it presents with hypoacusis and continuous otorrhea as symptoms. Because it is a rare disease, there are few studies in Brazil describing the characteristics of patients with the disease.This study aimed to determine the prevalence of cholesteatoma in patients with chronic otitis media and describe clinical, audiological and surgical characteristics of patients with acquired middle ear cholesteatoma treated at a referral hospital in the public health system.Cross-sectional and prospective cohort study, including 1710 patients with chronic otitis media, treated between August 2000 and June 2015, without prior surgery. Detailed clinical history, videotoscopy, and audiometry were performed, in addition to review of medical records to search for surgical data. Cholesteatomas were classified according to their route of formation.Of the patients with chronic otitis media, 419 (24.5%) had cholesteatoma; mean age of 34.49 years; 53.5% female and 63.8% adults. Bilateral cholesteatoma was observed in 17.1%. Anterior epitympanic cholesteatoma corresponded to 1.9%; posterior epitympanic, 32.9%; posterior mesotympanic, 33.7%; two routes, 14.8%; and indeterminate, 16.7%. The mean air-bone gap was 29.84dB and did not differ between routes of formation. There were no correlations between gap size and patient age or duration of symptoms. Of the surgical cases, 16.8% underwent closed tympanomastoidectomy and 75.2% open tympanomastoidectomy.The prevalence of cholesteatoma in patients with chronic otitis media was 24.5% and it was more common in adults than in children. Posterior mesotympanic cholesteatoma was more frequent, with no difference in mean air-bone gap between the different routes of formation. In patients undergoing surgery, open tympanomastoidectomy was the procedure most frequently chosen.

Marginal Tympanic Membrane Perforations: A Critical View

Otolaryngology (2014)

Sady Selamen Costa Letícia S. Rosito Inesângela Canali Yuri Petermann Jung Marcos Guilherme Tibes Pauletti

Objectives: (1) Assess the marginal perforation prevalence in patients with chronic otitis media (COM). (2) Analyze evidence suggesting prior moderate or severe tympanic retractions (TM) of the pars tensa in marginal perforation cases. (3) Correlate the abnormal findings with those in the contralateral ear (CLE). Methods: Prevalence study. The bilateral videotoscopies of 1510 patients diagnosed with COM in a tertiary hospital were analyzed. Previous TM retraction was evaluated according to: (1) medialization of the manubrium of malleus, (2) remnant tympanum adhered to the ossicular chain, (3) remnant tympanum adhered to the promontory, and (4) ossicular chain erosion. The videotoscopies of the CLE were also described. Results: Of the 1510 patients evaluated, 34 (2.25%) had marginal TM perforation. Only 5.9% of ears showed no evidence of previous retraction, and 88.3% showed 2 or more abnormal findings. The CLE was diagnosed with perforation‐retraction (2.9%), moderate or severe retraction (52.9%), and cholesteatoma (14.7%); 23.5% were normal. Conclusions: The study population had a low marginal perforation prevalence. The vast majority of ears with marginal perforation had evidence suggesting previous TM retraction. In addition, retraction or cholesteatoma occurred in 70.5% of CLE.

Ossicular Erosion and Air‐Bone Gap in Attic and Tensa Cholesteatomas

Otolaryngology (2014)

Sady Selaimen da Costa Letícia S. Rosito Inesângela Canali Fábio André Selaimen Yuri Petermann Jung

Objectives: (1) Compare the air‐bone gap between patients with posterior epitympanic (attic) and posterior mesotympanic (tensa) cholesteatomas. (2) Correlate the air‐bone gap and intraoperative ossicular chain findings. Methods: Cross‐sectional study. In total, 262 patients with attic and tensa cholesteatomas treated at a tertiary hospital were included. Audiometry was performed, and the pure tone average air‐bone gap (PTA‐ABG) was compared between the 2 groups. In addition, ossicles were classified as normal, eroded, or absent based on intraoperative evaluation. Data were compared using the Mann‐Whitney and Chi‐square tests, and statistical analysis was performed using SPSS. Results: Attic cholesteatoma was diagnosed in 51.1% of patients and tensa cholesteatoma in 48.9%. The mean patient age was 33 ± 18.7 years, and 52.3% were male patients. The PTA‐ABG was higher in tensa cholesteatoma cases than in attic cholesteatoma (30.25 ± 12.82 dB and 26.73 ± 13.08 dB, respectively, P =. 031). There were no differences in the malleus erosion or absence prevalence and the stapes suprastructure prevalence ( P =. 09 and P =. 17, respectively). The incus was normal in 17.6% of the attic and 6.3% of tensa cholesteatoma cases; eroded in 79.4% of tensa and 48.6% of attic cases; and absent in 33.8% of attic and 14.3% of tensa cholesteatoma cases ( P <. 01). Conclusions: The PTA‐ABG was higher in tensa cholesteatoma cases and correlated with a lower normal incus prevalence and a higher eroded incus prevalence compared to attic cholesteatoma cases.
