Nasosinusal chondrosarcoma with orbito-cerebral extension.

Chondrosarcoma is a highly aggressive malignant tumor originating from cartilaginous and mesenchymal tissues. The aim of this report is to describe a rare case of nasosinusal chondrosarcoma with orbito-cerebral extension. Our patient was a 55-year-old with a right cheek swelling evolving over a year, with unilateral right nasal obstruction gradually becoming bilateral associated with hyposmia, bilateral exophthalmos, reduced bilateral deep visual acuity and permanent headaches. The clinical examination found a tumor obstructing the two nasal cavities. Imaging showed a lobulated heterogeneous tissue process occupying the paranasal sinuses, with calcifications and enhancement at its periphery, extending to the orbito-cerebral area. The histopathological analysis was in favor of chondrosarcoma. The patient was first treated with an incomplete surgical resection by an endonasal route due to the extension to the orbit and the brain and received adjuvant radiotherapy. Surgical excision is a prognostic factor in this type of sarcomas and reduces recurrence rates.

Angiofibroma of the external auditory canal: a rare case with literature review.

Angiofibromas represent <1% of all head and neck tumors and occur primarily in the nasopharynx. Extra-nasopharyngeal angiofibromas are rarer. Remarkably, only a case of external auditory canal location has been reported. We present a case of an angiofibroma in this unique location in a female who presented with fullness of right ear and hypoacusis for 6 months. The clinical examination found a mass in the right external auditory canal attached to the posterosuperior wall. Preoperative audiometry revealed average right conductive hearing loss of 37.5 dB. A computed tomography scan revealed a mass on the right external auditory canal. Surgical resection of the mass was performed and the histopathological assessment confirmed the diagnosis. Post-operative audiometry showed an improvement in hearing function. There was no recurrence after 5 years. The prognosis of these tumors is good after total bloc resection.

Bilateral orbito-cerebral-extending frontal mucocele following nasosinus polyposis: A case report.

INTRODUCTION: and importance: Mucoceles are expansive pseudocystic formations, developed from the sinuses of the face, affecting mainly adults. Evolving at low noise, they are most often revealed by neurological or ophthalmological complications. We report a rare case of a bilateral frontal mucocele with orbito-cerebral extension following nasal sinus polyposis. CASE PRESENTATION: This was a 35-year-old patient with a history of Widal syndrome, who presented frontal headaches and left proptosis evolving for 4 months, in whom clinical examination revealed a left superomedial eyelid swelling, left proptosis and stage 2 nasosinus polyposis. Computed tomography and craniofacial magnetic resonance imaging were in favor of a bilateral frontal mucocele with left orbital and bilateral cerebral extensions. The patient was bilaterally operated by a combined approach including external Jacques eyebrow and endonasal Draf IIa procedure in addition to a radical total ethmoidectomy. The outcomes were favorable with regression of headaches and resolution of exophthalmos. CLINICAL DISCUSSION: The frontal mucocele, although benign, has an aggressive potential in the absence of treatment either towards the endocranium or the orbit behind the orbital septum causing intra-orbital extension, or in front of it; causing the dominant upper palpebral form as in the case of our patient. The treatment is still based on surgical excision of the cyst with drainage of the causal sinus, which was carried out for our patient. CONCLUSION: Despite its benign behavior, frontal mucocele may become serious by compression of neighboring organs which require an early and appropriate surgical management.

[Ossiculoplasties: about 30 cases and literature review]. / Ossiculoplasties: à propos de 30 cas et revue de la littérature.

The purpose of this study was to evaluate the functional outcomes of ossiculoplasties. We conducted a retrospective study, in the department of ear, nose and throat (ENT) and congestive cardiac failure (CCF) at the University Hospital Mohammed VI, in Oujda, from October 2018 to March 2020. Out of 45 patients with secondary otitis, 30 had gone ossiculoplasty using endoscopic transmeatal approach. These patients were enrolled in the study. The average age of patients was 31.8 years, with a F/M sex ratio of 1.5. The examination of the eardrum showed type A otitis (18 cases) type B otitis (5 cases), type C otitis (3 cases) and type D otitis (4 cases), according to Austin classification; 70% of patients who had undergone surgery had hearing loss between 30 and 40 dB and 30% of patients had hearing loss of ≥40 dB. Type II ossiculoplasty was performed in 26 cases, using tragal cartilage in 18 cases. Autologous incus interposition graft and placement of titanium PORP were performed in 4 cases each, whereas ossiculoplasty type III was performed in 4 cases, with placement of titanium TORP. Type II ossiculoplasty group had a hearing gain of ≥20 dB (all cases), whereas type III ossiculoplasty group had a hearing gain of ≥1 dB (1 case). Success rate was 90%. The analysis of these results shows that the overall outcome is slightly worse in patients undergoing type III ossiculoplasty than in those undergoing type II ossiculoplasty. However, comparative studies between the placement of prostheses and autografts or between different types of materials have only shown minor differences reported by the same author or the same team. Many authors highlighted that the preservation of the handle of malleus could provide better functional results.
