Double-handed endoscopic myringoplasty with a holding system in children: Preliminary observations.

OBJECTIVES: Endoscopic transcanal myringoplasty is a newly-introduced technique for reconstruction of tympanic membrane perforation that offers the advantage to obviate postauricular incision. The objective of this study was to evaluate the feasibility of a double-handed endoscope holder transcanal myringoplasty in children. This technique permits bimanual execution of the procedure and allows the surgeon to overcome the two significant issues of single-handed endoscope surgery, i.e. easy domination of a bloody field and smooth introduction of the graft. METHODS: A prospective non-randomized study of 10 consecutive primary endoscope holder-aided myringoplasties was performed; 3 mm or 4 mm 0° rigid endoscopes were used. A xenograft, biologic soft tissue, was applied in all cases. RESULTS: All procedures were performed successfully. Duration of surgery was faster than with a single-handed procedure and varied between 20 and 60 min. The tympanic membrane healed successfully in all patients. CONCLUSIONS: In this preliminary experience in children, a bimanual endoscopic holder-aided myringoplasty technique offers the possibility to overcome the obstacles encountered in a single-handed technique, since it can replicate the same concept of a bimanual microscopic approach and allow for easy management of a bloody field and introduction of the graft in the middle ear.

[Intranasal steroid therapy in inflammatory nasal-sinus pathology in pediatric age]. / La terapia steroidea intranasale nella patologia infiammatoria nasosinusale in età pediatrica.

Nasal obstruction is the symptom par excellence signalling the onset of nasal-sinus inflammatory pathologies (allergic rhinitis, acute or intermittent rhinosinusitis without nasal polyps, persistent rhinosinusitis without nasal polyps, chronic or intermittent rhinosinusitis associated with nasal-sinus polyposis). This symptom is due, in particular, to the host's response to the etiological factor for which, where there is no accompanying infectious process, the therapy should be aimed at resolving the inflammatory response. The anti-inflammatory properties of steroid drugs have been used systemically with excellent results. Unfortunately, prolonged use can foster the onset of major side-effects. Hence, the need to create new pharmacological molecules with topical action, while maintaining the characteristics of systemically used steroids. Up to the present, many intranasal steroids have been examined with positive results in inflammatory nasal-sinus pathologies. It should be noted that systemic bioavailability after intranasal therapy with mometasone furoate (MF) is lowest with respect to other steroid molecules. In recent decades topical intranasal steroids have also been tested in adenoid hypertrophy, a typical infant condition, with encouraging results. For this reason, the authors have assessed the effectiveness of MF on the reduction of the adenoid mass and, consequently, on the improvement in obstructive nasal symptoms in the short term and after a long-term follow-up, obtaining positive results. To conclude, intranasal steroid drugs are certainly useful in the treatment of nasal-sinus inflammatory pathologies. Furthermore, our studies have shown that MF can improve the clinical picture of adenoid hypertrophy.

Atypical carcinoid tumour of the larynx treated with CO2 laser excision: case report.

A case of atypical laryngeal carcinoid tumour of the right aryepiglottic fold is described in a 56-year-old female. The patient presented a 4-year history of dysphagia, occasional dyspnoea and pain originating in the right tonsillar fossa and radiating to the ear. A sessile, submucosal neoplasm of about 1 cm in diameter and apparently benign appearance was detected endoscopically in the supraglottic region. An excisional biopsy was collected by CO2 laser during direct microlaryngoscopy from which a diagnosis of atypical carcinoid tumour of the larynx was made, and later confirmed by histochemical and immunohistochemical staining. Post-operative course was uneventful, with return to a normal diet per os on the first post-operative day. Histopathological evaluation of the excised specimen revealed the presence of a neoplasm in proximity of the surgical margins, which were not, however, directly involved by the tumour. The close endoscopic follow-up was, nonetheless, implemented in order to promptly detect any evidence of relapse of the disease. After 18 months, a lesion, suspected of being a recurrence, was found, in the site of the original tumour. CO2 laser excision was again carried out, this time allowing for wider margins on the surgical resection. The post-operative diagnosis confirmed the clinical hypothesis of recurrence of atypical carcinoid tumour. The patient is presently alive and free from disease 7 years after the second endoscopic procedure. The difficult aspects of clinical and histopathological diagnoses, the surgical treatment as well as endoscopic and instrumental follow-up of this rare condition are discussed.

[Dacryocystocele in the adult: etiology, diagnosis and treatment]. / Il dacriocistocele in età adulta: eziologia, diagnosi e trattamento.

Dacryocystocele (DCC) is a pathologic condition frequently found in newborns as a consequence of congenital lacrimal system stenosis. Its occurrence in adult age is an exceedingly rare event and is secondary to inflammation, a neoplasm, facial trauma, or nasal surgery. Diagnosis is based on clinical examination, dacryocystography and computed tomography. Lacrimal system stenoses of the newborns usually recover spontaneously; only 2% to 4% of cases requires a treatment, which includes as a first step probing of the lacrimal system. If the clinical signs and symptoms persist, external or transnasal (endoscopic or microscopic) dacryocystorhinostomy (DCR) is indicated. The present work reports a case of adult DCC treated with endoscopic DCR. Rhinostomy was adequately stabilized and patent 33 months after surgery. The main advantages of the endoscopic compared to the external approach are: preservation of the pumping mechanism of the orbicularis muscle, low incidence of postoperative complications, simultaneous treatment of the nasal lesions, shorter hospitalization time, and absence of facial scars. Furthermore, the success rate for endoscopic DCR is similar to that obtained using an external approach.

Schwannoma of the nasal septum: a case report with review of the literature.

Schwannomas are neurogenic neoplasms rarely found in the sinonasal tract, where localization to the nasal septum is exceedingly rare (only 11 cases have been described in the western literature). We report the case of a 29-year-old white male with a schwannoma completely filling the left nasal fossa and arising from the bony part of the septum. A computer tomography (CT) scan and a biopsy suggestive of benign schwannoma were obtained before the lesion was removed by a degloving approach. The preoperative diagnosis of nasal septum schwannoma was confirmed. The patient is asymptomatic and without endoscopic evidence of recurrence 7 years after surgery. A review of the literature with particular emphasis on the clinical presentation, histological features, differential diagnosis and therapeutic options for such a rare lesion is included.

[Pleomorphic adenoma: a case treated by laryngotracheal resection and reconstruction]. / Un caso di adenoma pleomorfo trattato con resezione e ricostruzione laringo-tracheale.

Benign Pleomorphic Adenoma (PA) is a tumor rarely found in tracheal and laryngotracheal sites. A review of the literature published since 1922 has revealed only 30 certain cases of which 3 presented simultaneous involvement of both larynx and trachea. The present work describes the thirty-first case (the fourth with a laryngotracheal localization), diagnosed in a white, 40-year-old male who had been complaining of acute dyspnea for the last three years. Initially these symptoms had been interpreted as asthmatic crises. During one of these episodes, the patient underwent emergency tracheotomy and a laryngotracheoscopy revealed a rounded cricotracheal lesion with smooth surface and approximately 4 cm in cranio-caudal diameter. The mass occupied 90% of the air space and originated from the posterolateral right portion of the cricoid, and from the first 3 tracheal rings. CT and esophagoscopy ruled out its transmural invasion into the esophagus. Under rigid bronchoscopy, assisted NdYAG laser debulking was performed for biopsy purposes. The histological diagnosis was benign AP. For this reason a Grillo cricotracheal resection was performed with exeresis of the cricoid arch, mucosa of the cricoid plate and the first 4 tracheal rings. Reconstruction of the respiratory tract was achieved through termino-terminal cricothyrotracheal anastomosis. The initial diagnosis was confirmed and the resection edges were without evidence of neoplasm. Post-operative recovery proceeded without complications and the patient was discharged 7 days after surgery. Endoscopic and radiological follow-up after 30 months is still negative for any neoplastic recurrences. The laryngo-tracheal lumen is within the norm and cord motility has been preserved. The authors then describe the clinical, anatomopathological and radiological elements which prove useful in evaluating tracheal neoplasms and they underline the problems of differential diagnosis between benign AP and adenoid-cystic carcinoma. In addition, the various therapeutic options are discussed with special attention being focused on surgery through external approaches. Given the location of the AP described, the Grillo procedure-most commonly used in cases of inflammatory cricotracheal stenoses-proved well suited to the loco-regional control of the neoplasm. Stringent respect for some parts of this surgical technique make it possible to reduce post-operative complications to a minimum.

Endoscopic CO2 laser excision for tis, T1, and T2 glottic carcinomas: cure rate and prognostic factors.

We present the results of a retrospective study based on a cohort of 140 patients who underwent endoscopic CO(2) laser excision for previously untreated early glottic cancer (21 Tis, 96 T1, and 23 T2). This study used univariate analysis to review the impact on disease-free survival of 15 factors related to the host, the tumor, and the treatment. Recurrent cancer developed in 28 patients with an average interval to recurrence of 37.5 months. Retreatment consisted of different procedures, including laser excision, partial or total laryngectomy, and/or radiotherapy. The larynx was definitively preserved in 96% of patients. By the end of the study, 14 patients had died, but only 2 of them had died of the disease. Five-year overall survival and determinate survival were 93% and 98%, respectively. Ultimate local control at 5 years with CO(2) laser excision alone was 95% for Tis, 87% for T1, and 91% for T2 lesions. Only involvement of the anterior third of the vocal cord (P = 0.02), involvement of the false vocal cord (P = 0.02), and infiltration of the vocalis muscle (P = 0.004) showed a significant negative impact on disease-free survival.

[Endoscopic treatment of sphenoid aspergilloma]. / Il trattamento endoscopico dell'aspergilloma sfenoidale.

In recent years there has been an increase in fungal infections of the nose and paranasal sinuses, even though it is difficult to ascertain the incidence and prevalence of such disorders. The only information which can be drawn from the literature is that such infections are diagnosed in 6% to 13% of surgically treated chronic sinusitis. Aspergillus is the etiologic agent in approximately 80% of cases. Fungal infections are classified into two groups: non-invasive and invasive. The former includes mycetoma and allergic fungal sinusitis. The latter comprises the chronic indolent form, which presents slowly progressive bone erosion, and the fulminant form, which almost invariably carries a dismal prognosis. The maxillary sinus is involved in 80% of mycetomas, followed, in order of frequency, by the ethmoid and frontal sinus. Localization in the sphenoid sinus is exceedingly rare, with only 71 cases reported in the literature. Diagnosis of mycetoma is based on fungal cultures of nasal secretion (which are indeed of limited sensitivity, around 40%) and histological examination of the material removed from the sinus, which identifies the fungus in 80% of cases. CT and MR are highly sensitive diagnostic tools because of their ability to detect the presence of ferromagnetic substances (i.e. iron, magnesium and manganese) and calcium deposits in the diseased sinus. Four new cases of sphenoid mycetoma, treated with endoscopic surgery, are described. The advantages of the endoscopic approach compared to traditional techniques and the role of anti mycotic agents are also discussed.

Regional and distant metastases in laryngeal and hypopharyngeal sarcomas.

Cervical node and distant metastases are the most important prognostic factors in malignant laryngeal neoplasms. Owing to the unusual occurrence of laryngeal sarcomas, the prevalence of their metastases has never been analyzed in detail. We reviewed the laryngeal sarcomas reported in the literature and noticed that both regional and distant metastases are rare events and variable for different histotypes. These observations have obvious therapeutic and prognostic implications.
