Intrasinus bone mass encountered during a sinus lift: sequestrum or osteoma? Histological examination and postponed treatment

DDM and W. C. suggest different explanations for a bone mass in the sinus. They discuss removal, postponing the lift and histological examination; DDM also clarifies when the CT was acquired.

It is intrasinus. This is not a bone sequestrum.

Intrasunusale. Nessun sequestro

It's an osteoma.

I elevated the anterior sinus septum.

Furthermore, it has an Underwood septum anatomy.

It could be an osteoid osteoma or an ossifying fibroma.

Original text

Potrebbe essere osteoma osteoide. O fibroma ossificante

↳ Reply

I would like to remove it.

Assisted translation

Original text

io vorrei toglierlo

↳ Reply

That would require creating an access window and postponing the sinus lift.

Original text

significa forare e rimandare il rialzo

↳ Reply

If you remove it yourself, submit the specimen for histological examination.

Assisted translation

Original text

Se togli tu, provvedi ad esame istologico

↳ Reply

Of course, I'm sorry to have to postpone

Assisted translation

Original text

certo, mi dispiace dover rimandare

↳ Reply

Technically, I should not encounter any problems.

tecnicamente non dovrei avere probemi

What if I used resorbable sutures and stabilised the graft with fibrin glue?

Assisted translation

Original text

se suturassi con riassorbibile e stabilizzassi innesto con colla di fibrina?

↳ Reply

Strongly discouraged.

Assisted translation

Original text

Sconsigliato vivamente

↳ Reply

Unless a bone block stabilised with screws is used.

A meno di utilizzare blocco osseo stabilizzato con viti

Should it be placed in 4% formalin?

Assisted translation

Original text

va in formalina 4%?

↳ Reply

Between 3% and 10%; this must be agreed with the receiving pathology laboratory.

Assisted translation

Original text

Dal 3 al 10. Va concordato con l'istituto ricevente

↳ Reply

Why do you describe it as a bone sequestrum?

Assisted translation

Original text

Perché parli di sequestro?

↳ Reply

because it is not connected to anything

Assisted translation

Original text

perchè non è connesso a nulla

↳ Reply

It was clearly trapped within inflamed mucosal tissue that held it in place.

Assisted translation

Original text

chiaramente era imbrigliato in una mucosa infiammatoria che lo tratteneva

↳ Reply

Please keep us informed. If it is an osteoma, to my knowledge it requires intrasinus curettage to prevent recurrence. Thank you for sharing the case.

Assisted translation

Original text

Tienici informati! Perché se è un osteoma da quel che so necessita di un curettage intrasinusale altrimenti recidiva. Grazie della condivisione

↳ Reply

what I noticed, is that there was a lot of inflammatory tissue

Assisted translation

Original text

quello che ho notato, è che c era molto tessuto infiammatorio

↳ Reply

During membrane elevation, I felt a type of firm tissue. To describe the sensation approximately: imagine rubbing a finger over a drop of cyanoacrylate glue, which forms a harder layer on the fingertip. The membrane felt similar to that.

e quando ho scollato avvertivo una sorta di tessuto pseudo duro...per darvi la sensazione grossolanamente : avete presente quando strusciate il dito su una gocciolina di attack?si forma quello strato più duro sulla superficie del polpastrello. ecco la membrana era tipo così

↳ Reply

I am referring to the thickened portion, and I removed everything I could see.

Assisted translation

Original text

parlo della parte inspessita....e ho tolto via tutto ciò che ho potuto vedere

↳ Reply

Are you sure there was not a previous failed lateral-window sinus lift? The CBCT video you showed appears to reveal a lateral window.

Assisted translation

Original text

Sicuro che non ci sia stato il fallimento di un grande rialzo con botola laterale prima? Al video della cbct che hai mostrato sembra sia ststa effettuata una botola

↳ Reply

I am 100% certain that there was no previous failure.

Assisted translation

Original text

100% nessun fallimento

↳ Reply

I did it.

Assisted translation

Original text

l ho fatta io

↳ Reply

Yes, after opening the site and elevating the membrane.

Assisted translation

Original text

si, dopo aperto e scollato

↳ Reply

So the CBCT showing the osteoma inside the sinus was acquired afterwards. My apologies; I had not understood that.

Assisted translation

Original text

Quindi la cbct con l’osteona debtro la hai fatta dopo…scusami allora, non lo avevo capito

↳ Reply

to understand if it was connected to the medial wall

Assisted translation

Original text

per capire se era collegato alla parete mediale

↳ Reply

or if it was just floating

Assisted translation

Original text

o se era proprio fluttuante

↳ Reply

I didn't get it.

Assisted translation

Original text

Non l'ho ricevuta
