Facial nerve paralysis: Smile reconstruction using the masseteric nerve

September 21, 2015  |  Moustafa Mourad, MD; Christopher Linstrom, MD; Grigoriy Mashkevich, MD

Reanimation methods range from static slings and nerve transfers to dynamic muscle techniques, such as regional temporalis and free gracilis transfer.

Missed skull base injury during sinonasal surgery: A dangerous scenario still existing

August 27, 2015  |  Mohamed H. Hassab, MD; Ahmed Z. Eweiss, MD, FRCS(ORL-HNS); Ahmed A. Ibrahim, MD


Skull base injury is a known complication of sinonasal surgery. Cerebrospinal fluid (CSF) rhinorrhea has been reported to occur in 0 to 2.5% of these procedures. More extensive skull base injury may result in more serious complications. In this retrospective case series, we...

A case of bilateral internal auditory canal osteomas

January 21, 2014  |  Maria K. Brake, MD; David P. Morris, MD, FRCS(C); Jonathan Trites, MD, FRCS(C); S. Mark Taylor, MD, FRCS(C); Rene G. Van Wijhe, PhD; Robert D. Hart, MD, FRCS(C)


Osteomas of the skull base are rare, benign, slowly progressing growths of dense cortical bone. Osteomas occurring in the internal auditory canal are extremely rare. These lesions have sometimes been linked with dizziness, sensorineural hearing loss, and/or tinnitus. Although...

Endoscopic appearance of a healed skull base resection reconstructed with a pedicled nasoseptal flap

October 24, 2013  |  Hadia M. Leon, MD; Mark H. Tabor, MD

Expanded endonasal approaches to the skull base are becoming more common, and closure of CSF leaks with reliable separation of the sinonasal tract from the cranial cavity is critical to a successful outcome.

A case of chronic subdural hematoma following lumbar drainage for the management of iatrogenic cerebrospinal fluid rhinorrhea: Pitfalls and lessons

October 24, 2013  |  Vincent Eng-Soon Tan, MD, MRCS, MS(ORL-HNS); Donald Liew, FRACS


Chronic subdural hematoma as a complication of lumbar drain placement for the management of iatrogenic cerebrospinal fluid (CSF) leak has not been previously documented in the literature. We describe such a case in a 69-year-old man who presented with right nasal obstruction...

Langerhans cell histiocytosis: Temporal bone invasion in an adult

October 24, 2013  |  Richard L. Alexander, MD, PhD, MBA; Mary L. Worthen, BS; Changlee S. Pang, MD; John S. May, MD

Despite the characteristic of extensive destruction of the temporal bone in this disease, the facial nerve is surprisingly resistant to destruction, and facial nerve palsy is rare.

A study of persistent unilateral middle ear effusion caused by occult skull base lesions

April 18, 2013  |  John P. Leonetti, MD


The goal of this article is to review a series of patients with persistent unilateral middle ear effusion (MEE) and to suggest a more contemporary diagnostic algorithm. The author conducted a retrospective chart review of adults with persistent unilateral MEE and normal...

Skull base plasmacytoma with conductive hearing loss and an external auditory canal mass

July 5, 2012  |  Andrew I. Ahn, MD; Mary K. Wren, MD; Ted A. Meyer, MD, PhD


Skull base plasmacytomas are rare and difficult to differentiate clinically and radiologically from other tumors of the head and neck. Because of the risk of progression to multiple myeloma, early diagnosis is essential. We report the case of a 65-year-old...

Aneurysmal bone cyst at the base of the skull

May 1, 2012  |  Arun Goyal, MS; Shalabh Rastogi, MS; P.P. Singh, MS; Sonal Sharma, MD


Aneurysmal bone cysts have been described as pseudocysts in view of their lack of an epithelial lining. These cysts are uncommon, but when they do occur they typically involve the long bones of the extremities, the membranous bones of the thorax and pelvis, and the vertebrae....

Intracranial sarcoid granuloma as an extension of severe sinonasal sarcoidosis

April 1, 2012  |  Stephen M. Wold, MD and John T. Sinacori, MD


Sarcoidosis is a chronic, multisystem, granulomatous disease of unknown etiology. It manifests with a wide range of symptoms and clinical findings, including some that occur in the head and neck. Sinonasal sarcoidosis, in particular, frequently demonstrates a rather...

Multicentric giant cell tumor: Metachronous central and peripheral involvement

January 25, 2012  |  Alireza Karimi Yazdi, MD, Amir A. Sazgar, MD, and Ali Kouhi, MD


Giant cell tumors are rare in the head and neck region. The most frequently involved sites of giant cell lesions in the head and neck are the maxilla and mandible, whereas the sphenoid and temporal bones are rarely involved. This tumor is usually located in the long bones of...

Bilateral skull base osteomyelitis in an immunocompetent patient

December 15, 2011  |  Douglas Leventhal, MD, Thomas O. Willcox, MD, James J. Evans, MD, and Steven G. Finden, MD


A 75-year-old immunocompetent man presented to our office with right otalgia. After a comprehensive workup, he was found to have right temporal bone osteomyelitis and was treated with intravenous antibiotics. He then began to experience left-sided otalgia and was diagnosed with...
