Background: Otosclerosis is a primary osteodystrophy of the otic capsule that causes stapedo-vestibular ankylosis. Its diagnosis is suspected on the basis of clinical and audiometric elements, basically in the presence of conductive hearing loss with a normal eardrum. The CT-scan is an essential examination for the preoperative evaluation of otosclerosis. The aim of our study was to evaluate the use of CT-scanning in predicting the functional outcome of otosclerosis surgery by correlating postoperative audiometric results and preoperative CT findings., Methods: We conducted a retrospective study at the ENT Department in association with the Medical Imaging Department of our hospital, over a period of 8 years, from January 2014 to December 2022 and involving 90 patients (104 ears)., Results: The average age of our patients was 40 years with extremes ranging from 22 to 61 years. We noted a sex ratio of 0.38. The preoperative CT-scan showed signs of otosclerosis in 87% of the cases and infra-radiological forms in 13% of the cases. Veillon stage II was the most frequent radiological stage encountered with a percentage of 48%. A good audiometric evolution, defined by a closure of postoperative Air Bone Gap (ABG ≤ 20 dB) and by an improvement of Bone Conduction (BC gain ≥ 0), was recorded in 86 cases (82.7%) for ABG and in 84 cases (80.8%) for BC gain. Scanographic predictive factors of poor postoperative outcome for ABG and BC gain were: advanced stages (Veillon stage III and IV), endosteal effraction, and round window involvement. According to multivariate analysis, only the extent of otosclerotic foci was directly and independently associated with the postoperative audiometric outcome., Conclusion: The CT-scan is an essential examination in the preoperative evaluation of otosclerosis. It allows a positive diagnosis to be made and evaluate the extension of otosclerosis. Moreover, thanks to the analysis of the extent of the otosclerosis foci, mainly by the Veillon classification, the CT-scan allows to predict the postoperative audiometric prognosis., (© 2024.

Thyroglossal duct cysts (TDCs) are rare congenital cervical malformations in adults, which expose to two major risks: infection and malignant degeneration which remains the most dreaded complication in adults., Aims of the Study: This study aims to establish the clinical, management of TDC during adulthood, as well as the evolutionary aspects of these malformations in this age group., Patients Et Methods: This is a retrospective study on 61 adults over 18 years old, undergoing TDC surgery in our department., Results: The average age was 33.7 years with a sex ratio M/F of 1.10.The circumstances of discovery were dominated by a median cervical swelling in 53 patients (86,9%). The swelling was median in 28 cases and located in ad-hyoid in 32 cases. Cervical ultrasound confirmed the diagnosis of TDC in all patients. CT scans were performed on 15 patients. Surgical excision according to the Sistrunk method was performed on all patients. Three of our patients have experienced a degenerated TDC requiring total thyroidectomy with central neck dissection, followed by radioactive iodine therapy., Conclusion: CT scan keeps indications in adults. The treatment is surgical in order to prevent the risks degeneration, which is specific complication in adulthood.

Background and Objectives: We present the anatomical and functional results on the use of cartilage in myringoplasty and use the data to analyze the factors influencing hearing gain., Subjects and Methods: This retrospective study included 161 cases of cartilage myringoplasties collected over an 11-year period (2010-2020). Of the 161 cases, the etiology of the tympanic perforations was simple chronic otitis media in 154 (95.65%) ears and traumatic in 7 (4.35%) ears. The mean preoperative Rinne was 26.20±7.05 dB. The most commonly used approach was retroauricular, and the common graft material was tragal or conqual cartilage., Results: After the follow-up period (mean:15 months), the anatomical success rate was 93.2%; there were nine cases of reperforation, of which three were reoperated with a good final result. The hearing success rate (residual Rinne ≤20 dB) was 91.9% with an average gain of 11.48±8.62 dB. The only factor significantly influencing the anatomical outcome was the history of chronic rhinosinusitis. In univariate studies, several factors influencing the functional result were revealed; the only one retained after elimination of bias was the anatomical result., Conclusions: We recommend cartilage as the material of choice for myringoplasties as it has been shown to be resistant to predictive factors of failure after tympanic repair surgery. We recommend the adequate management of all chronic rhinosinusitis before performing myringoplasty.

Introduction: nasopharyngeal carcinomas (NPCs) are relatively common in the Mediterranean basin. Survival has been greatly improved by new radiation techniques and new molecular-targeted chemotherapy. The purpose of our study was to analyze the therapeutic outcomes and to describe the prognostic factors of NPCs., Methods: we conducted a retrospective study of patients with nasopharyngeal carcinoma on treatment and follow-up in our department between January 1995 and December 2014. Data were collected using a standardized sheet. Statistical analysis was performed using SPSS software. Kaplan-Meier method was used to determine patient´s overall survival., Results: seventy-three cases of NPC were reported. The average age of patients was 48 years. A male predominance was noted. The majority of cancers (56%) were locally advanced tumors (T3-T4). After an average follow-up of 45.5 months, the rate of locoregional recurrences was 19.4%. Three patients (4%) had bone metastases. Five-year overall survival was 65%. Factors positively influencing overall survival were early-stage tumor (TNM classification) and 1.8 Gy single fraction radiotherapy. Local and lymph node recurrence rates were 13.8% and 5.5% respectively, mainly for T4 N2 tumors. Therapeutic sequelae were dominated by seromucous otitis (42.7%), trismus (38.7%), and xerostomia (32%)., Conclusion: overall survival in patients with NPC has improved, in particular with the advent of concomitant radiotherapy and chemotherapy; however, disabling late toxicity is significant. Good prognostic factors reported in this study include early tumor stage as well as radiotherapy fractionation., Competing Interests: Les auteurs ne déclarent aucun conflit d´intérêts., (Copyright: Amel El Korbi et al.)

Inverted papilloma is a rare nasosinusal tumor that mainly occurs in adults during the 5 th decade. The occurrence in children is exceptional and only few cases have been reported in the litterature. Clinical and radiological findings mimic other benign nasosinusal pathologies; therefore, diagnosis is based on histopathology either via biopsy or following surgical excision. Here we present a rare case of pediatric inverted papilloma in a 11-year-old child and we discuss clinical, radiological, therapeutic and evolutionary features through a literature review., Competing Interests: The authors declare no competing interests., (Copyright: Amel El Korbi et al.)

Castleman's disease is a rare pathology, poorly understood. It is considered as a lymphoproliferative disorder, described for the first time in 1954, which may be confused with other causes of lymphadenopathy. We report in this paper the case of a young women presenting with left latero-cervical lymphadenopathy. All the investigations were negative except a large high-vascularized level II cervical lymphadenopathy. We performed a cervicotomy. The extemporaneous histological exam was non-contributive. We decided to perform a complete level II and III left cervical lymphadenectomy. The diagnosis of unicentric Castleman's disease was confirmed based on the final histological study of the specimen, and the absence of other cervical and extra-cervical lymphadenopathy. The patient is free of recurrence at the time of reporting this article., Competing Interests: The authors declare no competing interests., (Copyright: Amel El Korbi et al.)

We report a rare case of salivary duct carcinoma and we study its clinical and evolutionary features. A 64-year-old patient was referred for right peripheral facial paralysis. MRI showed suspected formation of the right parotid gland. Treatment included total parotidectomy and ipsilateral neck lymph node dissection. The histology concluded to a ductal carcinoma of the parotid with lymph node metastasis. Radiation therapy has been indicated. Salivary duct carcinoma of the parotid gland is a highly aggressive and uncommon tumor. Treatment of localized forms is based on surgery and radiotherapy., (Copyright © 2020 Société française de radiothérapie oncologique (SFRO). Published by Elsevier Masson SAS. All rights reserved.)

Mucoceles are slow-growing paranasal sinus cystic masses whose clinical presentation varies according to the affected sinus. Diagnosis is often radiological, based essentially on CT scan. The aim of this work was to study the radiologic characteristics of mucoceles on CT scan and MRI. We conducted a retrospective study of patients with mucoceles explored by imaging and operated on in our department. In our series, fronto-ethmoidal sinuses were the most frequently affected (81%). Facial scan confirmed the diagnosis in the majority of cases. Magnetic resonance imaging (MRI) was performed in 4 cases. Eleven patients were operated on by endonasal approach, three by external approach and one by combined surgical approach. Recurrence was observed in two patients after an average delay of 24 months. CT scan is considered the method of choice in the investigation of mucoceles. MRI is indicated in some cases to assess any orbital or intracranial extension., Competing Interests: The authors declare no competing interests., (© Rachida Bouatay et al.)

This study aimed to determine the diagnostic value of fine needle aspiration biopsy (FNAB) and of its contribution to the management of parotid tumors. We conducted a retrospective study of 47 patients who had undergone parotidectomy as well as preoperative fine needle aspiration biopsy. The study highlighted that eighty one percent of patients had a benign tumor while 19% of patients had a malignant tumor. The sensitivity and specificity of FNAB were 78% and 92% respectively. Parotid tumors were correctly classified as malignant or benign in 89% of cases, overall accuracy was 64.4%. FNAB is a reliable examination providing preoperative informations about the treatment plan and the postoperative course., Competing Interests: Les auteurs ne déclarent aucun conflit d'intérêts.

Thyroglossal duct carcinoma is a rare pathologic entity. The surgeon's main concern is whether to perform thyroidectomy or not. In this paper, we report another case of thyroglossal papillary duct carcinoma in a 14-old girl suspected preoperatively and confirmed postoperatively on the histological analysis of resected specimen by a Sistrunk procedure. Therapeutic strategy was completed by a total thyroidectomy with radioactive iodine therapy and suppressive levothyroxine therapy. In the absence of clear guidelines, the management of thyroglossal duct carcinoma is depending on the clinical situation and the experience of the team of surgeons., Competing Interests: The authors declare no competing interests.

Complications occur in 3% of the cases of frontal sinusitis. These are mainly oculo-orbital, intracranial and osteomyelitis. Our aim is to describe the contribution of different imaging modalities in the diagnosis of these complications and their post-treatment monitoring. within a 15 years period (2000-2014), 10 patients with complicated frontal sinusitis were included into this retrospective study. 10 patients (9 males) aged 9 to 70 year old (mean 28). Two of these patients (20%) had a history of craniofacial trauma. Frontal headache was present in all cases (100%), frontal swelling in 8 cases (80%) and unilateral palpebral edema in 3 cases (30%). A CT scan of the face and brain was performed in all cases and revealed frontal osteomyelitis in 6 cases (60%), extradural empyema in 3 cases (33%), intracranial frontal abscess in 2 cases (20%) and occulo-orbital complications in 3 cases (30%). Magnetic resonance imaging was performed in one patient and demonstrated thrombosis of the upper longitudinal sinus. 40% of our patients associated 2 complications. Cross-sectional imaging is important in early and accurate diagnosis of complicated frontal sinusitis., Competing Interests: The authors declare no competing interest.

Posttraumatic Unilateral paralysis of the last four cranial nerves (IX-XI), known as collet-Sicard syndrome, is rare following closed head injury. A 21-year-old man presented with slurred speech, hoarseness voice and difficulty swallowing his saliva following closed head trauma. The cranial nerve examination revealed left sided severe dysfunction of cranial nerves VII, IX, X, XI, and XII. A CT-Scan of the neck was performed demonstrating a fracture of the left styloid process at the base of the skull. The Magnetic Resonance Imaging showed unusually well seen lower cranial nerves due to nerve edema. The patient was managed conservatively with steroids and regular sessions of neuromuscular and orthophonic rehabilitation. The nutrition had to be administered by gastrostomy since he was unable to swallow. Six months after the injury a total neurological recovery was noted. We present the exceptional case of Collet-Sicard Syndrome caused by styloid process fracture.
