Research paper thumbnail of Type I Tympanoplasty in Adolescence : Prognostic Factors and Surgical Outcomes

Different views have been reported concerning this procedure in young ages and the best moment to perform surgery remains controversial. Surgery in early adolescence appears to achieve the same outcomes than adulthood and without disadvantages of childhood. Characteristics of perforation and the functioning of the Eustachian tube were proposed as determinants of prognosis; however their effect also remains unclear. This study aims to analyse the success rates of type I tympanoplasty in adolescence and ascertain the existence of variables that may predict surgery outcomes. Subjects and methods: We present a retrospective study of 52 teenagers who undergone type I tympanoplasty, between January 2004 and December 2013. We analysed the impact of age, site, size and cause of perforation, state of middle ear and the existence of contralateral disease on anatomic and aud...

Successful ossiculoplasty depends on several factors. This retrospective study was carried out to analyze hearing results of ossiculoplasty in ears with chronic otitis media (COM) and evaluate clinical outcomes and factors predictive of hearing improvement. Subjects and methods: We reviewed the results of 153 patients with COM (with cholesteatoma (COMC) and without cholesteatoma (COMWC)) who underwent ossiculoplasty between January of 2002 to December of 2011. Several potential prognostic factors were evaluated: cholesteatoma present vs absent; type of surgical procedure, state of the middle ear mucosa, state of the ossicular chain, type of prosthesis. Results: We analyzed 153 ossiculoplasties: 96 patients presented COMWC and 57 patients presented COMC. The ossiculoplasties were performed using autologous ossicles for the most part. All ossiculoplasties were carried out in one-stage surgery. In 38% of cases ossiculoplasty was combined with mastoidectomy; in the remaining 62% of cases, ossiculoplasty was performed without mastoidectomy. Ossiculoplasty was successfully achieved in 113 patients (74%). The presence of the stapes superstructure and normal mucosa were significant predictive factors of surgical success. Conclusion: The majority of the ossiculoplasties improved hearing status satisfactorily. Multivariate analysis should be performed to investigate prognostic factors of favorable short-term hearing outcomes after ossiculoplasty. Better knowledge of these predictive factors may contribute to the surgeon's judgment and the information given to patients.

Research paper thumbnail of Abnormal Congenital Location of Stapes’ Superstructure: Clinical and Embryological Implications

Most part of them are usually associated with other malformations, such as aural atresia, microtia, and dysmorphic craniofacial features. A clinical case of a 24-year-old male with a right-sided conductive hearing loss since his childhood, without craniofacial malformation, is presented. He was proposed for exploratory tympanotomy under the suspicious diagnosis of otosclerosis. The surgery revealed an abnormal location of stapes’ superstructure, which was attached to the promontory and had an isolated and mobile osseous footplate in the oval window. A stapes prosthesis was inserted and resulted in closure of the air-bone gap by 25 dB. A review of the literature was also performed using MEDLINE. Two theories diverge on the embryologic origin of the stapes. Our findings seem to be in favour of the theory that defines two different embryologic origins to the stapes.

Research paper thumbnail of Respiratory Epithelial Adenomatoid Hamartoma: Diagnostic Pitfalls With Emphasis on Differential Diagnosis

Advances in Anatomic Pathology, 2007

The lesion can be confused with a variety of benign and malignant entities, including inflammatory polyp, inverted schneiderian papilloma, and low-grade sinonasal adenocarcinoma. In reviewing the historical, clinical, gross, and histopathologic features of REAH and its subtypes, we elucidate how the distinction of REAH with florid mucinous metaplasia from low-grade adenocarcinoma can be challenging particularly in the setting of small biopsy samples. Diagnostic criteria are reviewed with emphasis on key distinguishing characteristics. The significance of this distinction is paramount in preventing unwarranted surgery and untoward consequences for the patient.

Several methods have been developed to reduce its morbidity. Cold dissection is one of the most used techniques. Tonsillectomy can be associated with operative and postoperative complications. With the onset of Ambulatory Surgery, this procedure began to be performed as outpatient surgery. The present work aims to determine the postoperative surgical complications, ascertain the rate of postoperative bleeding and identify possible risk factors for these complications. We reviewed all tonsillectomies and adenotonsillectomies performed from January 2010 to December 2013. There were 647 surgeries, 58% made as outpatient surgery. The postoperative complications were severe sore throat (5.4%), vomiting (3.1%), fever (2.2%) and hemorrhage (1.1%). The severe sore throat was more common in adults (p The bleeding was equally distributed among patients performed in conventional or outpatient practice. Complications ve...
