Objectives: The treatment of all forms of sinonasal inverted
papilloma (IP) is a complete, wide, local resection. The main
surgical purpose is to remove all diseased mucosa and mucoperiosteum, together with a cuff of normal-looking mucosa at
the attachment site, followed by drilling and/or coagulation.
Our aim is to present our experiences in endoscopic surgical
management of IP by using attachment-oriented excision.
Methods: We present 20 cases of sinonasal IP. The data collected include the histopathological diagnosis, staging, extension of the tumor, tumor attachment site, approach to surgery,
serum squamous cell carcinoma antigen (SCCA) level, and
recurrences.
Results: All patients underwent endoscopic surgery. A
Caldwell-Luc operation was required in addition to the endoscopic surgery in 1 case. There was 1 case of recurrence (5%).
After the additional operation, there was no recurrence. The
tumor attachment sites vary, and the case of recurrence had a
wide attachment site at the primary surgery. No major intraoperative or postoperative complications were observed.
Conclusions: The present study shows that attachment-oriented excision for IP is useful for complete resection of IP.
Surgeons should choose the surgical approach according to
the location of the tumor attachment site rather than the Krouse
staging system.
Bony Hemangioma of the Ethmoid Sinus
Christian Caceres (Presenter); Kathryn Kreicher;
Todd E. Falcone, MD
Objectives: We present a rare case of a bony hemangioma of
the ethmoid sinus.
Methods: Case report and review of the literature.
Results: A 71-year-old man with a remote history of nasal
trauma presented to the otolaryngology clinic with complaints of long-standing nasal congestion, postnasal drip, and
decreased sense of smell. In-office nasal endoscopy revealed
a fleshy, erythematous mass in the right middle meatus and
septal deviation toward the right. Computed tomography
(CT) of the sinuses revealed an approximately 2-cm mass in
the right ethmoid sinus with an internal calcified matrix. The
patient was offered surgery for definitive diagnosis and treatment and underwent right-sided endoscopic sinus surgery
with complete excision of the mass and septoplasty. Final
pathology revealed a bony hemangioma of the ethmoid sinus.
Conclusions: Bony hemangiomas arising within the nasal
cavity are exceedingly rare, with only 2 cases arising in the
ethmoid region. Intranasal bony hemangiomas have varying
presentations including headache, recurrent epistaxis, nasal
congestion, and hyposmia, although some can be asymptomatic. Radiologic examination with CT is helpful in making a diagnosis because CT delineates margins and may
illuminate a characteristic appearance of a honeycombed

mass with multiple cavernous spaces. En bloc resection
using a transnasal endoscopic approach with or without preoperative embolization is the treatment of choice for intranasal bony hemangiomas. Intranasal bony hemangioma
should be included in the differential diagnosis of an erythematous, firm, nasal mass.
A Case of Acute Invasive Fungal Sinusitis
in an Immunocompetent Patient on
Glatiramer Acetate Therapy
Emma C. Panico (Presenter); Carlos N.
Prieto-Granada, MD; Justin P. McCormick; Melanie D.
Hicks; Do-Yeon Cho, MD
Objectives: Acute invasive fungal sinusitis (AIFS) is a lifethreatening, rapidly progressive, angioinvasive infection.
AIFS classically presents in immunocompromised patients,
particularly in those with cellular immunodeficiency. With the
advent of immunomodulatory therapies, the patient population at risk for AIFS has broadened.
Methods: This case report describes an immunocompetent,
nondiabetic patient with a history of multiple sclerosis (MS)
who was maintained on immunomodulatory therapy for the
treatment of MS. We review the natural history and progression and AIFS, discuss the suspected mechanism of glatiramer
acetate, and review recent literature discussing AIFS in an
otherwise immunocompetent population.
Results: A 70-year-old woman with a history of MS being
treated by glatiramer acetate, a nonbiologic, noninterferon disease-modifying agent, was evaluated for acute vision change,
with computed tomography scan revealing an enhancing mass
in the left pterygopalatine fossa and inferior orbital fissure.
Endoscopic sinus surgery was performed with path-ology demonstrating AIFS. The patient was initiated on amphotericin
nasal rinses, amphotericin B lipid complex, and posaconazole.
Serial operative debridements were subsequently performed,
and a follow-up magnetic resonance imaging scan at 6 months
showed no disease progression. Glatiramer acetate was discontinued, and her MS has been stable since.
Conclusions: The interest in immune-modulating drug development has surged over the past decade. As such, disease processes, such as AIFS, that historically target the immune
compromise, are being reported in otherwise immunocompetent patients. Recognizing this unique subset of at-risk patients
is important because early identification and treatment is crucial in avoiding morbidity and mortality.
Central Skull Base Osteomyelitis Presenting
With High Vagal Injury: A Case Report and
Review of the Literature
Miriam Smetak, MD (Presenter); Carey Burton Wood, MD;
Benjamin Ray Campbell, MD; Shiayin F. Yang, MD
Objectives: We present a case report of a 76-year-old man
with history of multiple myeloma and myelofibrosis status
after stem cell transplant with central skull base osteomyelitis
presenting with high vagal injury.
