[Hyperbaric oxygen therapy application in otorhinolaryngology and head and neck surgery: state of the art and review of literature]. / Applicazioni dell'ossigenoterapia iperbarica in otorinolaringoiatria e in chirurgia cervico-facciale: stato dell'arte e revisione della letteratura.

Hyperbaric Oxygen Therapy (HOT) encompasses an extensive research area in which new indications, some of which are now well-codified, have emerged both in the fields of medical and surgical pathology. Its utilization in carefully targeted clinical situations, in which its true efficacy can be demonstrated, is first of all connected with medicolegal responsibility, in suspected iatrogenic accidents; its application must furthermore be subordinated to a favourable cost/benefit ratio for the health service employing it. In otorhinolaryngology and head and neck surgery, HOT is a strategic therapeutic weapon in several applications. Its most widely recognized indications are radiation lesions, chronic osteomyelitis of the mandible, head and neck infections, malignant external otitis, sudden hypoacusia, chronic tinnitus, encephalitis, treatment of the gasseous embolus, skin grafts, vascularized flaps, cervicoencephalic traumas. HOT indications as a radiosensitizing and/or chemiosensitizing factor are still being studied. Both a review of the literature and our experience appear, beyond any doubt, to confirm that HOT promotes faster recovery and reduces hospital stays, thus qualifying as a new therapeutic aid that complements the usual well-established methods.

[Complications of tracheostomy in critically ill patients: comparison of dilation and surgical techniques]. / Confronto sulle complicanze di varie tecniche tracheotomiche in area critica.

The tracheotomy, one of the oldest surgical procedures, has in recent years been the focus of particular attention given the undoubted, and not always justified, increase in indications, and by the introduction of dilatational tracheotomy techniques, particularly in critically patients. The present work compares the standard surgical tracheotomy with the more recent percutaneous techniques (Ciaglia dilatational tracheotomy and Fantoni translaryngeal tracheotomy). In particular, the relationship between the technique adopted, timing and complications were analyzed for 215 tracheotomies performed at different Intensive Care Units at our Hospital between 1993 and 1998 (106 performed using the standard surgical technique, 51 with the Ciaglia technique and 58 with the Fantoni technique). The pre-operative oro-tracheal intubation time ranged between 4-54 days (17 tracheotomies performed before oro-tracheal intubation). The results of this study showed that percutaneous techniques present fewer early post-operative complications (severe bleeding, erosive stomitis, dislocation of the cannula) and above all fewer sequelae in time (tracheal stenosis, tracheomalacia). The surgical procedures are shorter and nursing is limited to a few days which certainly results in a savings in health care resources. After decannulation, the esthetic result in patients that underwent the dilatational tracheotomy can be considered excellent. Among the disadvantages one must recall the possible dislocation of the cannula immediately after surgery: forced reinsertion of the cannula exposes the patient to the risk of creating a dangerous false route. The results obtained are statistically significant and in line with those found in the literature. The conclusion is drawn that, when performed by skilled surgeons and aided by endoscopy, the percutaneous tracheotomy techniques are the method of choice for patients in critical areas.

[Reconstructive strategies in head and neck cancer: case history review from 1992 to 1997 (154 cases)]. / Strategie ricostruttive in oncologia cervico-cefalica: revisione della casistica (154 casi) degli anni 1992-97.

Technological progress in reconstructive surgery, in particular the use of pedunculated or free flaps, has given new impetus to head and neck dissection. This stems from the fact that such techniques provide greater oncological radicality, reduce the number of severe post-operative complications and give better quality of life. The present study examines 154 patients suffering from upper aero-digestive tract neoplasms (131 males and 23 females; age range 23-82 years) who had undergone radical surgery. Reconstruction was performed with flaps in 154 cases: 119 pedunculated flaps (102 large myocutaneous pectoral and 17 temporal muscle flaps) and 35 free flaps (18 radial osteofasciocutaneous, 13 radial fasciocutaneous and 4 omentum flaps). Analysis of the individual districts showed that the flap of choice was the temporal muscle flap when surgery involved the soft parts of the orbital-maxilly-zigomatic area and the rhinopharynx. This is because it is highly moldable and reliable. In surgery of the oral cavity and oropharynx the grand pectoral flap is most frequently used as it provides enough tissue for the reconstruction, adequately protects the vascular-nerve axis in the neck and it is quick and easy. However, the functional results are not the best and there is some alteration in the initial phases of deglutition. To reduce these problems, the authors encourage the use of free flaps which provide good results from both the functional and esthetic points of view. They are, however, more difficult to perform and this leads the authors to conclude that they should only be selected for certain patients (long life expectancy, female, young, etc.). In the center where the authors work the flap of choice is the radial fasciocutaneous or osteofasciocutaneous flap. In surgery of the hypopharynx and larynx reconstruction is normally performed with a grand pectoral myocutaneous flap, sculpted as needed for the individual case. In this region, reconstruction proves functionally satisfactory even when there is a minimum of residual mucosa. Finally, for reconstructive surgery of the apex, the omentum free flap was used as it is malleable and can be used to reconstruct broad areas of dissection. The esthetic and functional results, the low incidence of complications and the greater quality of life suggest that this type of flap be extended to the surgery of locally advanced tumors in combination with an accurate, valid reconstructive solution.
