An undulating vallecular cyst

April 30, 2018  |  Yu-Hsuan Lin, MD; Ming-Yee Lin, MD, PhD

Most vallecular cysts are indolent, but they carry the potential for airway obstruction if they become enlarged.

Dentigerous cyst

March 14, 2018  |  Lester D. Thompson, MD

Endoscopic endonasal management of recurrent maxillary mucoceles using biliary T-tube stenting

December 12, 2017  |  Noritsugu Ono, MD; Shin Ito, MD; Hirotomo Homma, MD; Hiroko Okada, MD; Junko Murata, MD; Katsuhisa Ikeda, MD, PhD

Abstract

Mucoceles of the paranasal sinus can be managed endoscopically with an extremely low recurrence rate. Frontal sinus mucoceles can sometimes be prevented from closing and reforming by stenting, which to the best of our knowledge has not yet been reported in the maxillary sinus....

Maxillary sinus mucoceles and other side effects of external-beam radiation in the pediatric patient: A cautionary tale

September 18, 2017  |  Anthony Sheyn, MD; Tate Naylor, MD; Felicity Lenes-Voit, MD; Eric Berg, MD

Abstract

A sinonasal mucocele can develop after the obstruction of a sinus ostium, which can occur secondary to trauma, infection, a neoplasm, or an iatrogenic cause. These mucoceles typically arise in the frontal and ethmoid sinuses. Sinonasal mucoceles are epithelium-lined cysts that...

Adenoid cystic carcinoma of the head and neck area: Oncologic treatment and plastic-reconstructive options

June 20, 2017  |  Johannes A. Veit, MD; Julia Thierauf, MD; Thomas K. Hoffmann, PhD, MD; Jens Greve, PhD, MD; Nicole Rotter, PhD, MD; Patrick J. Schuler, PhD, MD; Marc O. Scheithauer, PhD, MD

Abstract

Adenoid cystic carcinoma of the head and neck area is a rare malignant tumor with acceptable short-term but mediocre long-term prognosis. Radical tumor excision with clear resection margins, and sometimes resection of the facial nerve due to perineural growth, remains the...

Large pediatric maxillary dentigerous cysts presenting with sinonasal and orbital symptoms: A case series

April 30, 2017  |  Shakil Ahmed Nagori, MDS; Anson Jose, MDS; Ongkila Bhutia, MDS; Ajoy Roychoudhury, MDS

Abstract

Dentigerous cysts are benign odontogenic cysts associated with the crowns of unerupted, embedded, or impacted teeth. Most of them are associated with mandibular third molars, followed by maxillary third molars and canines. They are usually asymptomatic, and rarely do they grow...

Thyroglossal duct cyst

February 20, 2017  |  Lester D. Thompson, MD

Most patients present with a mobile, painless midline neck mass, usually inferior to the hyoid bone, showing movement with tongue protrusion.

Mucous retention cyst of mastoid bone mimicking cholesteatoma

January 25, 2017  |  Nurdoğan Ata, MD; Suna Erkılıç, MD

Occlusion of mastoid cells and the aditus ad antrum caused by inflammatory diseases can result in poor ventilation and poor drainage of mastoid cells, which can in turn cause the formation of cysts.

Endoscopic view of balloon dilation for excision of a sphenoid cyst

January 25, 2017  |  Dewey A. Christmas, MD; Joseph P. Mirante, MD, FACS; Eiji Yanagisawa, MD, FACS

The sphenoid sinus can be opened for ventilation, inspection, or biopsy from a transethmoid or transnasal approach after identifying its ostium.

October 31, 2015  |  Robert Saadi, BS; David Goldenberg, MD, FACS

Thyroglossal duct cysts  are classically midline, associated with the hyoid bone, move with swallowing or tongue protrusion, and often initially present with some degree of inflammation.
