In the LOUPE
Globulomaxillary cysts are so-‐called as they were once believed to be caused by entrapment of epi-‐thelium between the nasal and maxillary processes called the globulomaxillary region between the maxillary lateral incisor and the adjacent canine.
The typical signs and symptoms of the so-‐called cysts are convergence of crowns of the maxil-‐lary cuspid and lateral incisor, so> texture and crepi-‐ta?on. More o>en though, they are accidentally dis-‐covered during rou?ne imaging studies as they could be completely intrabony.
Radiographically, their characteris?c ap-‐pearance is that of radiolucency between the roots of the maxillary lateral incisior and cuspid, causing divergence of roots of these teeth.
Since 1992, in the WHO classifi-‐ca?on of the cysts of the jaws, the globulomaxillary cyst has been con-‐sidered “of debat-‐able” origin.

Gree?ngs from the Philippine College of Oral and Maxillofa-‐cial Surgeons!
We welcome you to the PCOMS Annual Conference!
This newslePer is a PCOMS publica?on to guide you with the updates of the PCOMS Scien?fic event for 2014. This news-‐lePer will also help you in your prac?ce of oral and maxillo-‐facial surgery as we prepared some guidelines, nomencla-‐ture and updates in oral surgery.
I would personally like to thank the Publica?on Chair of this newslePer, Dr. Jay Hansel Tabije and PCOMS Fellows who contributed to this and for coming up with this 1st PCOMS newlePer.
Godspeed!

SHEDDING LIGHT...FROM PAGE 1
Christ, in the 70’s, a>er thorough evalua?on of literature, con-‐cluded that facial processes do not exist per se and therefore, ecto-‐derm cannot be trapped in these fissures, and these so-‐called globu-‐lomaxillary cysts should not be classified as fissural cysts. Not all literature though considered these cysts an “obsolete” en?ty as pub-‐lished in the 1993 by D’Silva and Anderson.
However, more recent literature (Shear, 1996) show more evidence against globulomaxillary cysts being fissural cysts than the evidence sugges?ng they are such. Today’s literature agree that the en?ty of globulomaxillary cyst should be used only as a clinical descrip,ve name 1rela?ve to its loca?on in the globulomaxilary region; and the inverted pear-‐shaped radiolucency found be-‐tween the maxillary lateral incisor and the cuspid.
Studies support that ma-‐jority of these lesions are of peria-‐
pical origin. Keratocys?c odonto-‐genic tumor have been described histologically for the globulomaxil-‐lary cysts. Some also revealed Rushton bodies, a feature not pre-‐sent in fissural cysts.
Histologically the so-‐called globulomaxillary cyst can be
any of the following odontogeninc lesions: periapical cyst, keratocys-‐?c odontogenic tumor, rarely ade-‐nomatoid odontogenic tumor, and squamous odontogenic tumor 1,2. Furthermore, Aisenberg and In-‐man also reported a case of ame-‐loblastoma developing in a globu-‐lomaxillary cyst.
At present, defini?ve di-‐agnosis for cysts in this region is needed for defini?ve treatment and prognosis.

ACOMS comes to Manila in 2016
The Asian Association of Oral & Maxillofacial Surgeons conducts this biennial congress hosted by the different affiliate societies in each of the member Asian country. Last 2012 in Bali Indonesia during the 10th Asian Congress on Oral & Maxillofacial Surgery (ACOMS) the Philippine College of Oral & Maxillofacial Surgeons (PCOMS) won the bid to host the 12th ACOMS.
This is the largest scientific congress in Asia on Oral & Maxillofacial Surgery and it will be held in Manila. This congress will feature world renowned experts on topics ranging from minor to major oral surgical procedures, trauma,
reconstructive surgery and implants to name a few. International and local exhibitors showcasing the finest materials and instruments and other activities provide an added flare to this international event.
Start marking the date November 9-12, 2016 at the SMX Convention Center, Mall of Asia Complex, Pasay City, Philippines.
