Rimozione di cisti mucose dal seno mascellare in associazione all’elevazione del pavimento sinusale : una nuova tecnica microinvasiva con accesso intra-orale
No full textObiettivi. L’obiettivo di questo lavoro è quello di presentare una nuova tecnica chirurgica micro-invasiva, con approccio intra-orale, che consente l’enucleazione di grandi cisti mucose del seno mascellare contestualmente all’elevazione del pavimento sinusale, al fine di evitare l’ostruzione dell’ostio sinusale, preservando l’integrità del periostio schneideriano.
Materiali e metodi. Dal 2004 al 2012, 12 pazienti candidati a un grande rialzo del seno mascellare a scopo implantologico, e affetti da ampie cisti mucose sinusali occupanti almeno 1/3 del volume del seno mascellare, sono stati sottoposti alla rimozione della cisti contestualmente all’elevazione del seno mascellare. Attraverso un piccolo accesso osteotomico, posto apicalmente al margine superiore dell’opercolo osseo necessario al rialzo del seno mascellare, la lesione è stata sottoposta ad aspirazione del suo contenuto liquido e a successiva enucleazione, preservando l’integrità del periostio schneideriano. Gli impianti dentali (numero=19) sono stati inseriti contestualmente alla procedura di rialzo oppure dopo 7-9 mesi di guarigione, in relazione alle dimensioni della cresta ossea residua.
Risultati. Nessun caso ha evidenziato complicanze intra- o post-operatorie né recidive delle lesioni cistiche. Il follow-up medio dopo la finalizzazione protesica è stato di 50 mesi (range: 12-96 mesi), con successo degli impianti e della relativa riabilitazione protesica pari al 100%.
Conclusioni. Nonostante il numero limitato di pazienti, gli autori ritengono che la tecnica chirurgica presentata possa costituire un’alternativa terapeutica semplice ed efficace per l’enucleazione di cisti mucose del seno mascellare in pazienti candidati a interventi di grande rialzo a scopo implantologico.Purpose. The purpose of this study is to present a new micro-invasive intra-oral surgical
technique that allows the removal of large maxillary mucosal cysts (MMC) during sinus
floor elevation via a lateral approach, to prevent obstructions of the osteo-meatal complex
(OMC). The integrity of the schneiderian periosteum is preserved with this procedure.
Materials and methods. From 2004 to 2012, twelve patients scheduled for a maxillary
sinus elevation and affected by MMC involving at least 1/3 of the maxillary sinus volume
were treated with a sinus lift procedure via a lateral approach and simultaneous removal
of the maxillary cyst through a small accessory bony access, located above the upper
border of the bony window performed for sinus floor elevation. Initial suction of the
cystic liquid with a fine needle was followed by the enucleation of the lesion through the
accessory bony window, preserving the integrity of the schneiderian periostium over the
maxillary sinus floor. Dental implants were inserted during the sinus floor elevation or
during a second stage procedure, 7 to 9 months later. A total of 19 implants were placed.
Results. No patients developed intra- or post-operative complications, with no cyst
recurrences. The mean follow-up after the prosthetic rehabilitation was 50 months (range:
12 to 96 months). The success rate of implants and related prostheses was 100%.
Conclusions. Despite the limited number of patients, this technique seems to represent a
simple and effective procedure that allows MMC removal in patients scheduled for a sinus
floor elevation procedure via lateral approach
Sinus grafting and simultaneous removal of large antral pseudocysts of the maxillary sinus with a micro-invasive intraoral access
No full textLarge antral pseudocysts of the maxillary sinus (APCs) may hamper the elevation of the Schneiderian membrane during sinus grafting and may impair osteo-meatal complex patency after sinus augmentation. Therefore, these should be removed prior to or at the time of sinus grafting. This study presents a new technique that combines enucleation of large APCs during sinus grafting via a lateral approach with preservation of the Schneiderian membrane periosteal layer. Twelve patients underwent a sinus graft via lateral approach during the years 2004-2012. Simultaneous APC removal was achieved through a small additional bony access, preserving the integrity of the periosteal layer of the Schneiderian membrane. Nineteen implants were inserted at the time of sinus augmentation or during a second stage. Prosthetic rehabilitation was started at 4-6 months after implant placement. No patient developed surgical complications or APC recurrence. The survival rate of implants and related prostheses was 100% over a mean follow-up of 50 months (range 12-96 months) after completion of the prosthetic restorations. This technique may represent an effective procedure to achieve APC removal at the time of sinus grafting, preserving the integrity of the Schneiderian membrane periosteal layer
