RESUMO
BACKGROUND: Paediatric tympanoplasty is now a common surgical procedure. The age from which it could be proposed varies regarding children specificities such as Eustachian tube dysfunction, the high incidence of upper airway infections and the immaturity of the immune system. The aim of this study is to describe the specific constitutional, epidemiological and operative aspects as well as the anatomical and functional results of tympanoplasty in children. METHODS: From 2014 to 2018, a cohort of 95 patients with ages between 6 and 16 years, operated for a type I tympanoplasty, was reviewed by analysing the medical history, the epidemiological and clinical parameters, in addition to the operative features and the functional results. RESULTS: The mean age at surgery was 11,7 years. The main risk factors of tympanic perforation were recurrent otitis (78,9%), auricular trauma (16,8%) and tonsillar and adenoid hypertrophy (7,4%). Good anatomical postoperative results with a closed and reinforced neo-tympanic membrane were seen in 90 (94,7%) cases, while a significant improvement of the hearing loss was observed in 87 (91.6%) patients, with a mean value of 34,23 dB HL before and 21,9 dB HL after surgery (p < 0,0001). CONCLUSIONS: The indications of type I tympanoplasty in the paediatric population remain a subject of debate, but still offer good anatomical and functional results as long as it is adapted to each particular case.
RESUMO
Parotid gland tumor is complex and poses diagnostic and therapeutic problems. The purpose of this study was to assess the role of extemporaneous examination in the management of patients with parotid gland tumors. We report a pro and retrospective analytical study of a series of cases of salivary gland tumors, whose data were collected in the ENT and in the department of cervical-facial Surgery at the University Hospital in Casablanca, between January 2012 and December 2015. Seventy two cases of parotid tumors were recorded. The sex-ratio (H/F) was 0.94, 0.76 for patients with benign tumors and 1.62 for patients with malignant tumors. The average age was 47 years (15- 75 years). The median of consultation time was 40 months. Clinical symptoms were dominated by parotid swelling (100%), pain in 25% of patients, facial palsy in 6%, and cervical adenopathies in 10%. Ultrasound was recommended in 80% of patients. MRI was performed in 26% of cases. All patients underwent surgery, 76% of patients underwent exofacial parotidectomies and 24% total conservative parotidectomies. This treatment was associated with ganglion resection in 24% of cases and radiotherapy in 24% of cases. Extemporaneous examination was performed in 71% of patients, its susceptibility was 89% and its specificity 88%. Definitive histological diagnosis was confirmed by anatomopathological examination in all cases. We confirmed benign and malignant tumors in 71% and 29% of cases respectively. Benign tumors were dominated by pleomorphic adenoma (59%), while malignant lesions were dominated by mucoepidermoid carcinoma (38%). The postoperative course was marked by: discrete haematoma in 4% of cases, transient facial palsy in 15%, superinfection of the wound in 3% and post-parotidectomy Frey´s syndrome in 3% of patients. One patient had labial recurrence of acinar cell carcinoma. No cases of death were noted. Parotid gland tumors are characterized by a great histological variability. Differentiation between malignant tumor and benign tumor is often difficult. Currently, MRI is the imaging test of choice. Extemporaneous examinationis is very useful intraoperatively when it is necessary to communicate with the pathologist. Multidisciplinary approach is adopted including ENT, oncological, radiotherapeutic, pathological and radiological approaches. Prognosis depends on the histological type, the stage of progression and treatment.
