The discovery of stapes.

Giovanni Filippo Ingrassia revisited and redefined some of Galeno's reports, and was recognized as one of the leading Italian Physicians of the 16th century. Ingrassia principally studied the skull, and gave very important contributions to otorhinolaryngology, including the discovery of the stapes. He also isolated the inferior nasal concha from the maxillary bone, described the frontal sinus, the pterygopalatine fossa and several foramina of the skull. Ingrassia firstly attributed a sensorial function to the middle ear bones, which he called fifth particular function. He also added some details to the description of the VIII cranial nerve, which introduces the concept of bone conducting sound. The most important discovery in Ingrassia's study about the hearing organ was the first description of the third bone of the ossicular chain that he called "stapes". Ingrassia should thus be reconsidered under a new light for his important discovery and for his intuitions about the stapes and its role in hearing. It is appropriate for a Sicilian physician to be placed at his rightful place side-by-side with Eustachio and Valsalva in the history of otology.

Malignant peripheral nerve sheath tumour (malignant epithelioid Schwannoma) of the parotid gland.

PROBLEMS/OBJECTIVES: Malignant peripheral nerve sheath tumours are uncommon soft tissue tumours originating from Schwann cells or nerve sheath cells. Malignant epithelioid schwannoma is an aggressive variant of malignant peripheral nerve sheath tumour, and unfortunately is related with a high rate of recurrence and poor prognosis. METHODOLOGY: In this study we present a rare case of malignant epithelioid schwannoma of the parotid gland and we discuss its origin, unusual presentation, and possible treatments options. RESULTS: Patient underwent total parotidectomy without neck dissection. Postoperative radiotherapy and chemotherapy management were not necessary. CONCLUSION: Patients with malignant epithelioid schwannomas typically present with pain and/or rapid enlargement of a pre-existing lesion but the diagnosis of these tumours remains difficult as it is based primarily on clinical suspicion. There is no recognized management for this tumour yet while the prognosis seems to correlate best with the extent of surgical resection (Fig. 4, Ref. 16).

Intermediate nerve schwannoma: a rare tumour.

The intermediate nerve (IN), also called the nerve of Wrisberg, is a relatively small nerve with a variable anatomical course. Currently, this nerve is not addressed well in the pertinent literature. Pre-operative diagnosis of IN tumours is clinically challenging due to the lack of related symptoms. Symptoms are typically caused by the functional deterioration of neighbouring anatomical structures. In this report, we describe a patient with a schwannoma that arose at the porus acusticus of the internal auditory canal; during surgery, this proved to originate from the IN. We discuss our findings in the context of previously reported cases of IN schwannomas and analyse the vague characteristics and symptoms of this rare tumour.

Obstructive sleep apnoea syndrome (OSAS): effects on the vestibular system.

Aim of the present study was to evaluate the effects of obstructive sleep apnoea syndrome (OSAS) on the peripheral and central vestibular system, by means of a case series prospective study at the University referral centre of Otolaryngology Head and Neck Surgery; 45 consecutive patients suffering from OSAS were compared with a control group of 30 volunteer subjects selected from among the department employees. Severity of the disease was evaluated by means of cardio-respiratory function monitoring during sleep; the apnoea-hypopnoea index was calculated. Both groups underwent: 1) head and neck examination; 2) fibre-optic examination; 3) pure tone audiometry; 4) evaluation of eye movement disorders using oculomotility tests recorded with the help of video-nystagmography; 5) caloric vestibular responses recorded with video-nystagmography; 6) auditory brainstem response. Results, when evaluating our data, showed that the peripheral vestibular system may become asymmetric due to hypoxic damage while the central vestibular system corrects this disequilibrium.

Management of tinnitus: oral treatment with melatonin and sulodexide.

The main problem arising from tinnitus is the disturbance it causes in day-to-day life and disturbance in sleep leading to fatigue and general discomfort. We attempted to study the effect of melatonin in conjunction with Sulodexide as a treatment method for tinnitus and evaluate its effectiveness. We studied 102 patients suffering from tinnitus with a Prospective Randomised Controlled Study conducted in a tertiary care ENT department. After randomisation, 34 patients were treated with melatonin and Sulodexide, another 34 were treated with melatonin alone, and the remaining 34 (control group) were managed without therapy in order to evaluate spontaneous variations in quality of tinnitus. Patients were assessed prospectively with Tinnitus Handicap Inventory and Acufenometry both pre-treatment and post-treatment. Among the patients we studied, we found better results with both Tinnitus Handicap Inventory and Acufenometry in the group who received melatonin and Sulodexide as against melatonin alone. Any improvement was noted in the control group. In conclusion, our opinion is that melatonin in combination with Sulodexide is a viable treatment option for patients suffering from central or sensorineural tinnitus.

Delayed facial nerve paralysis post middle ear surgery: herpes simplex virus activation.

UNLABELLED: Delayed facial nerve paralysis post middle ear surgery: herpes simplex virus activation. PROBLEM: Facial nerve paralysis following middle ear surgery is a nightmare for the otology surgeon. Usually this is caused by surgical trauma or local anaesthetic use. It is uncommon to see onset of facial nerve palsy more than 72 hours following the surgery. METHODOLOGY: We report a case of facial nerve paralysis appearing 11 days following a successful canal wall-down mastoidectomy. RESULTS: Viral screening for Herpes Virus type 1 confirmed the viral aetiology of the delayed facial paralysis. CONCLUSION: When an ipsilateral facial nerve palsy appears more than 72 hours after an uneventful middle ear procedure, without symptoms of any infection, suspect a viral reactivation.

Treatment of central and sensorineural tinnitus with orally administered Melatonin and Sulodexide: personal experience from a randomized controlled study.

Since very little is understood about the exact aetiology of tinnitus, this has made treatment of the condition difficult. Even though approximately 10-15% of the general population suffer from tinnitus, only 2% consider it serious enough to warrant any treatment. The main problem arising from tinnitus is the disturbance it causes not only in day to day life but also in sleep, leading to fatigue and general discomfort. The present study focused on the effect of Melatonin in conjunction with Sulodexide as a treatment method for tinnitus. Overall, 102 patients suffering from tinnitus were evaluated in a prospective randomised controlled study conducted in a tertiary care ENT department. After randomisation, 34 patients were treated with Melatonin and Sulodexide, another 34 were treated with Melatonin alone, while the remaining 34 (control group) were managed without treatment in order to evaluate spontaneous variations in the quality of tinnitus. Patients were assessed prospectively with the Tinnitus Handicap Inventory and Acufenometry, both pre- and post-treatment. Among the patients studied, better results with both Tinnitus Handicap Inventory and Acufenometry were found in the group who received Melatonin and Sulodexide compared to those receiving Melatonin alone. No improvement was observed in the control group. In conclusion, Melatonin in combination with Sulodexide is, in our opinion, a viable treatment option for patients suffering from central or sensorineural tinnitus.

Uvulopalatopharyngoplasty with tonsillectomy in the treatment of severe OSAS.

OBJECTIVE: To establish the efficacy of uvulopalatopharyngoplasty with tonsillectomy for treating selected patients with severe obstructive sleep apnea syndrome. METHODOLOGY: Retrospective study of patients who underwent clinical/instrumental evaluation and surgical treatment. SETTING: University ENT division with a tertiary snoring referral center. PARTICIPANTS: Twenty-two patients with normal body mass index affected by severe obstructive sleep apnea syndrome. MAIN OUTCOME MEASURES: Pre- and post-operative cardiopulmonary monitoring during sleep, daytime sleepiness evaluation, post-treatment complication recording. RESULTS: Complete response to therapy was obtained in 78% of patients. Four patients had relief of symptoms but retained apnea/hypopnea index scores greater than 5. CONCLUSIONS: Uvulopalatopharyngoplasty associated with tonsillectomy can beemployed safely to treat patients with normal body mass index who suffer from severe obstructive sleep apnea.

Pleomorphic adenoma of the lateral nasal wall: case report.

Pleomorphic adenoma is the most common tumour of the salivary glands. However, it is extremely rare for these to originate in the nose and even when they do so, it is most commonly in the nasal septum. It is important to be aware of the paucity of presenting symptoms (nasal obstruction and epistaxis), as the lesion may not be recognized immediately. Growth is generally restricted locally and the tumour is not known to spread to the neighbouring structures. Surgical resection is the treatment of choice. Recurrences and evolution to malignancy are not frequent, but long-term follow-up is recommended. The case is presented of pleomorphic adenoma arising from the lateral wall of the right nasal cavity, in a 34-year-old male, which was resected completely, endoscopically. Histological and immunohistochemical evaluation revealed the presence of a pleomorphic adenoma.

Nasal septal polyps: a report of two cases.

PROBLEM: It is common to see nasal polyps arising from the lateral wall of the nose; however, polyps arising from the nasal septum are rare. Diagnosis of such lesions is usually made by nasal endoscopy and confirmed by computer tomography. METHODOLOGY: Two cases of isolated nasal septum polyps were diagnosed from 150 consecutive functional endoscopic sinus surgeries. Both patients had septal deviation; only one had a history of allergy. The polyps were completely excised in both cases; the septal deviations were not corrected. RESULTS: Both patients remain disease-free after two and three years of follow-up. CONCLUSIONS: Nasal septal deviation does not seem to play an important role in septal polyp development, whereas local nasal inflammatory factors appear to be important for the genesis of septal polyps. Limited resection using a functional endoscopic surgical approach is the best choice of treatment to prevent recurrence of polyps.

The Picture Archiving and Communication System: a useful tool in a case of upper oesophageal foreign body.

We present a case of an oesophageal foreign body (approximately 2x2 cm) which was not seen on the initial lateral soft tissue neck X-ray but was detected following manipulation of the X-ray using the Picture Archiving and Communication System of X-ray viewing. This system gives the user much greater flexibility, including a choice of magnification and contrast.
