Forty patients were treated or followed up for aesthesioneuroblastoma between 1980 and 1995 at Institut Gustave Roussy, France. There were three T₁; seven T₂, 15 T₃and 15 T₄lesions. The cervical metastatic rate at presentation was 18 per cent. Distant metastases were detected by bone marrow biopsy and bone scan in three patients at presentation. Treatment modalities included surgery alone in eight patients, radiotherapy alone in three patients, combined modality surgery plus radiotherapy in 11 patients, chemotherapy alone in two patients, chemotherapy plus radiotherapy in 10 patients, and multimodality therapy chemotherapy plus surgery plus radiotherapy in six patients.The five-year survival rate was 51 per cent. Multimodality treatment offered better survival (63 per cent at five years) and disease-free interval (54 months). Overall local, regional, and distant failure rates were 58 per cent, 15 per cent and 40 per cent respectively. Distant metastases commonly occurred in bone (82 per cent). Cervical metastasis was an unfavourable prognostic indicator (0 per cent survival at two years).In conclusion, aesthesioneuroblastoma is sensitive to chemotherapy and radiotherapy. Multimodality therapy should be used initially.

Obstructive sleep apnea (OSA) syndrome is a multi-factorial disorder. Recently identified pathophysiological contributing factors include airway collapsibility, poor pharyngeal muscle responsiveness, a low arousal threshold, and a high loop gain. Understanding the pathophysiology is of pivotal importance to select the most effective treatment option. It is well documented that conventional treatments (continuous positive airway pressure (CPAP), upper airway surgery, and dental appliance) may not always be successful in the presence of non-anatomical traits, especially in mild to moderate OSA. Orofacial myofunctional therapy (OMT) consists of isotonic and isometric exercises targeted to oral and oropharyngeal structures, with the aim of increasing muscle tone, endurance, and coordinated movements of pharyngeal and peripharyngeal muscles. Recent studies have demonstrated the efficacy of OMT in reducing snoring, apnea–hypopnea index, and daytime sleepiness, and improving oxygen saturations and sleep quality. Myofunctional therapy helps to reposition the tongue, improve nasal breathing, and increase muscle tone in pediatric and adult OSA patients. Studies have shown that OMT prevents residual OSA in children after adenotonsillectomy and helps adherence in CPAP-treated OSA patients. Randomized multi-institutional studies will be necessary in the future to determine the effectiveness of OMT in a single or combined modality targeted approach in the treatment of OSA. In this narrative review, we present up-to-date literature data, focusing on the role of OSA pathophysiology concepts concerning pharyngeal anatomical collapsibility and muscle responsiveness, underlying the response to OMT in OSA patients.

Forty-two patients were treated for sarcoma of the nasal cavity and paranasal sinuses at the Institut Gustave Roussy, Paris, between 1960 and 1993. Twelve patients had chondrosarcoma (CS), 14 had osteosarcoma (OS) and 16 had fibrosarcoma (FS). Ten patients had grade I, six grade II and 26 grade HI tumours. All but 10 patients had surgery for the primary tumour. A significantly increased risk of local failure was associated with the male sex (p <0.01), grade III tumours (p <0.02) and patients excluded from surgery (p <0.04). The overall incidence of local and distant failure was 76 and 12 per cent respectively. Overall survival was 28 per cent at three years and 23 per cent at five years. Eight patients (20 per cent) were alive more than 10 years later. The factors significantly influencing survival were sex (p <0.01), grade (p <0.05) and local failure (p<0.01).

A clinicopathological study of 51 cases of adenoid cystic carcinoma in the head and neck region seen over a period of 20 years is presented. The correlation between various histological features and their impact on the results is attempted. Longterm results with respect to loco-regional recurrences, distant metastases and survival with various modalities of therapy are presented. Although this is a small series, radical surgery in keeping with the aim of avoiding undue mutilation, thus preserving the quality of life, followed by a full course of radiotherapy has been the mainstay of treatment and the results here presented justify this approach.
