ABSTRACT
Nasal tip under projection is often found in rhinoplasty cases both for congenital or post-traumatic deformity. Nasal trauma may result in alteration of the external and internal nasal structures with following aesthetic impairment and difficulties in breathing. Post-traumatic surgery is frequent, but restoration of pre-traumatic form and function remains a challenge. The present paper describes a new method to increase tip projection by a columellar strut harvested from the autologous nasal bone and cartilage of the resected hump. A total of 15 cases (11 women/4 men, mean age 32.6 ± 12.3 years) of major tip projection/misalignment abnormalities to be corrected by increased nasal tip projection were drawn, and all underwent closed or open rhinoplasty with the placement of a bony columellar strut harvested from the resected hump of the patient. Short and long-term advantages of this procedure are to be underlined. Harvesting is routinely performed during dorsal resection and preparation of the graft is easy. Differently from bone of the vomer or the inferior turbinate, this is cortical bone straight in shape and rigid in framework, and therefore ideal to gain reliable tip support overtime. No additional harvesting areas are needed. Placement of this bony strut is carried out in the standard fashion without additional dissection or further procedures. Long-term follow-up shows maintained projection over time. This graft can be combined with various grafting or suturing techniques usually applied according to each surgeon's experience and the needs of each patient.

The drooping tip deformity is both a bothersome aesthetic feature and functional impairment of the nose. Both static and dynamic factors may affect tip appearance and it seems logical to take into account these factors when planning correction of drooping tip. Many studies have examined this topic, but its treatment remains controversial. In order to make nasal tip surgery successful, it is useful to identify the keystone anatomical characteristics of the tip itself. Naso-labial angle, nostril axis, tip rotation angle according to Frankfort plane and columellar-facial angle may be measured to assess nasal tip position. The present study focuses on the authors' personal experience on the key anatomic changes of the nose that deserve correction and on the main surgical steps needed to achieve consistent results when dealing with a drooping tip. Pre- and post-operative nasal tip rotation and projection were studied. Correction of the drooping tip was accomplished by an open or closed septorhinoplasty approach according to patient's needs. The surgical techniques mostly employed for tip repositioning was septum straightening (41/41) and tongue-in-groove (36/41 cases) (87.8%). A columellar strut was used in 8/41 (19.51%) cases. LLC cephalic resection was applied in 29/41 patients (70.73%), LLC re-orienting sutures were made in 18/41 cases (43.9%) and lateral crural overlay was needed in 2/41 (4.8%). The key anatomic changes of the nose that deserve correction and the surgical steps needed to ease the often intriguing pre-operative decision-making process are reviewed.

The aneurysmal bone cyst (ABC) is a solitary, expansile, non-neoplastic bone lesion, described as a distinct clinicopathological entity by Jaffe and Lichtenstein. We report a case of an ABC arising from the nasal bone in a adult male patient treated with complete surgical excision.
ABSTRACT
PERFORATION OF THE NASAL SEPTUM MAY HAVE MULTIPLE CAUSES: traumatic, iatrogenic, infectious, degenerative, overuse of vasoconstrictors, abuse of cocaine and more recently chemotherapy agents. Perforations are also classified according to their size and type of cartilaginous or osteocartilaginous deficit, as well as location (front, middle and rear). Many surgical techniques have been proposed to repair the perforation, although the results are often unsatisfactory for perforations of small and medium size; in large perforations permanent obliteration of the defect cannot always be ensured. It is often necessary to use tissues from inside the nasal turbinates or cartilage from other donor sites such as the ear or rib, and various techniques are discussed in light of the recent literature. The perforations observed in the last eight years and surgical approaches performed in open or closed approaches are taken into account. The authors propose a new technique that has been used with success in many types of septal perforation regardless of aetiology, and in particular large perforations, which allows for the use of the osteocartilaginous donor site as a hump. It is also useful in reductive rhinoseptoplasty, which targets selection to easily obtain mucopericondral flaps with an extramucosal technique and to obtain also an aesthetic improvement.

OBJECTIVE: Mucosa-associated lymphoid tissue (MALT) lymphoma of the salivary glands occurring in 6 patients affected by primary Sjögren's syndrome is reported. METHODS: Clinical findings, histologic type, stage, treatment and outcome of the 6 patients have been revised. RESULTS: In all 6 cases the lymphoma was of the MALT type. Four patients had stage IE disease, 1 patient had stage IIE disease and 1 patient had stage IV disease. The patients received different treatments resulting in all cases in prolonged remission. After 7 years of complete remission 1 patient developed a diffuse large B-cell lymphoma. CONCLUSION: MALT lymphoma of the salivary glands is an indolent disease. Though the best therapy of this lymphoproliferative disorder remains to be established, prolonged remission has been obtained in our cases with different therapeutic approaches. We review the literature regarding the relationship between Sjögren's syndrome and MALT lymphomas and study the mechanisms which may be involved in the transformation from a lymphoepithelial lesion into a neoplastic disorder.

We describe a 68-year old woman affected by chronic hepatitis C virus infection; hypertransaminasemia was first observed at the age of 46 years, when the patient was diagnosed uterus carcinoma. Since 1994 she had complained of xerostomia, xerophtalmia, pain at the left parotid and laterocervical adenomegaly. Neck ultrasound examination revealed enlarged intraglandular, submandibular and laterocervical lymph nodes. Fine-needle aspiration of both left parotid and laterocervical lymph nodes was not diagnostic. The histologic examination of the surgical biopsy of the left parotid and the right submandibular salivary gland allowed to diagnose mucosa-associated lymphoid tissue lymphoma (MALT lymphoma). The patient was given alpha-interferon obtaining a clinical remission of the lymphoma and transitory normalization of transaminase level. The authors review the literature about some aspects of MALT lymphomas: a) the etiopathogenesis of MALT lymphomas and the mechanisms suspected to be involved in the evolution from a "benign" lymphoepithelial infiltrate to a neoplastic disorder; b) the relationship between chronic inflammatory diseases as Sjögren's syndrome and chronic C virus infection and MALT lymphomas, particularly MALT lymphomas of the salivary glands; c) the significance of the evidence of a B-cell clonality in the context of a lymphoepithelial lesion; d) diagnostic and therapeutic aspects of MALT lymphomas of the salivary glands.

Identification of the specific pathophysiological processes and correlation with post-operative hearing are the prerequisites for utilizing electrophysiological audio monitoring techniques in preventing damage to auditory structures during vestibular Schwannoma (VS) surgery. The present paper compares the value of auditory brainstem responses (ABRs), electrocochleography (ECochG) and directly recorded cochlear nerve action potentials (CNAPs) in detecting damage to auditory structures during VS surgery and predicting post-operative hearing. Eighteen consecutive patients operated on for VS, in an attempt at hearing preservation, participated in the investigation. The ipsilateral hearing level (pure tone average [PTA] 0.5-3 kHz) ranged from 10 to 50 dB HL (mean: 30.7 dB HL), with a speech discrimination score equal to or better than 50 per cent. CNAPs furnished the highest predictive score for post-operative hearing. In particular, when a permanent loss of CNAPs occurred the sensitivity and specificity were 100 per cent. The discrepancies between the ECochG and CNAP findings were attributable to high prevalence of cochlear nerve damage, capable of 'disconnecting' the ear from the central auditory pathways, causing persistence of peripheral auditory function and no propagation of the neural input. ABR monitoring was highly sensitive in detecting auditory damage but its prognostic utility was marred by its poor specificity.

The authors stress that conservative correction should be the main goal in rhinoplasty in general and in the surgical treatment of the nasal tip in particular. After outlining contemporary concepts and criteria relating to the modeling of an aesthetically pleasing nasal tip and the consequent surgical planning for its achievement as well as the specific indications for tip plasty, they go on discuss the technical aspects of tip projection and rotation. A personal technique is proposed for reshaping and sculpturing the tip, completed by a double interdomal suture with different application points during closed rhinoplasty. The technique also involves ancillary procedures consisting in the execution of a series of incisions with a radial pattern at the domal level and, when necessary, in the undersurface of the lateral crus. The procedure is explained in detail and the results are illustrated and discussed.

Surgery of acoustic neuroma (AN) has significantly refined over the past years due to a series of advances in diagnostics and surgical technique. Electrophysiologic investigation performed during surgery has greatly contributed to this progress, increasing the surgeon's understanding of the mechanism of damage and suggesting various changes in his or her surgical strategy.In this context, the advantages of the retrosigmoid "en-bloc" removal of small to medium size ANs have been examined in the present study. At the ENT Department of the University of Verona, 103 subjects with AN were operated on, from January 1990 to December 1995, with a retrosigmoid-transmeatal approach. Eighteen subjects (17.4%) presented pure a intracanalar (IC) tumor and 85 (82.6%) had both IC and extracanalar (EC) involvement. All the IC tumors (n = 18) and 70 of the IC-EC neuromas with an EC size less than 25 mm are reported in this paper for a total of 88 patients. The first 48 patients were operated on via the classic procedures described in the literature, characterized by removal of the tumor after "debulking" and limited exposure of the internal auditory canal (IAC). The following 40 subjects were operated on according to the technique of "en-bloc" removal of the tumor and wide exposure of the IAC.In the "en-bloc" group the tumor was first detached from the cerebellar flocculus and the pons, when necessary. The tumor was not debulked to preserve the anatomic relationship with the nerves and to facilitate identification, cleavage and dissection of the tumor from the neural structures. Thereafter, the posterior wall of the IAC was drilled out and opened in a circumferential range from 180 to 270 degrees . The IAC dura was subsequently opened, and the distal end of the AN along with the vestibular nerves were identified. The vestibular nerves were sectioned in the distal portion of the IAC and dissected with the tumor from the underlying facial and cochlear nerves. Dissection continued medially to the IAC porus. The AN was progressively dissected from the cochlear and facial nerves in the cerebellopontine angle (CPA) with multiple direction maneuvers, as required by the characteristics and degree of adherence to the neural structures.The anatomic and functional results obtained with this new procedure ("en-bloc" removal) were compared with the classic "debulking" technique. The statistical analysis shows an improvement in postoperative outcome for both auditory and facial nerve function. The "en-bloc" removal procedure along with the wide exposure of the content of the IAC and electrophysiologic monitoring of the seventh and eighth cranial nerves are, in our experience, the recommended strategies for improving outcomes in small to medium size ANs.
ABSTRACT
Parotid gland biopsy was performed in 32 female patients affected by suspected Sjögren's syndrome. In all cases histologic findings were in agreement with this diagnosis and in two subjects led us to detect the malignant transformation into lymphoma. None of the patients developed relevant complications. Our study indicates that parotid gland biopsy in Sjögren's syndrome is a safe procedure and may be useful in performing diagnosis.

The authors emphasize the importance of MRI as a means to functionally evaluate patients in primary (PR) and secondary (SR) rhinoseptoplasty. Forty-eight subjects were appraised who underwent various types of corrective nose surgery: 31 PR, 12 SR, 4 introgenic perforations, and 1 dermoid cyst of the nasal dorsum. MRI allows the nasal structures at the level of the valve to be visualized, as well as the medial and lateral walls of the nasal fossa in all of its components. MRI studies improve pre-surgical evaluation (alar cartilages, iaterdomal distance, and valvular configuration), and the exam of structures and anomalies which are hard to evaluate by the rhinoscopy (turbino-septal-synchias, perforations, losses of bone-cartilaginous substance). Moreover, through MRI the nasal respiratory surface (NRS) is determined and used by the authors to quantify the improvement of the postsurgical nasal respiratory function. All of these points gain importance during the planning of primary, secondary, and/or corrective surgery.

Acute functional narrowing of the glottis frequently leads to an inappropriate diagnosis of asthma. Only 2 cases have been reported of patients with asthma and concomitant vocal cord dysfunction. We present the case of an adolescent boy with asthma, who exhibited a worsening of wheezing and a reduction in peak expiratory flow rate out of proportion to symptoms due to a vocal cord dysfunction.
