Chapter 70 / Otolaryngology: Head and Neck Surgery 615

What are the disadvantages?

May result in increased mortality from

 

 

local recurrence

FACIAL FRACTURES

 

 

 

 

MANDIBLE FRACTURES

 

 

 

 

What are the symptoms?

Gross disfigurement, pain, malocclusion,

 

 

drooling

What are the signs?

Trismus, fragment mobility and

 

 

lacerations of gingiva, hematoma in floor

 

 

of mouth

What are the possible

Malunion, nonunion, osteomyelitis, TMJ

complications?

ankylosis

What is the treatment?

Open or closed reduction

 

 

MMF MaxilloMandibular Fixation

 

 

(wire jaw shut)

MIDFACE FRACTURES

 

 

 

 

How are they evaluated?

Careful physical examination and CT scan

Classification

 

 

 

 

Le Fort I?

Transverse maxillary fracture above the

 

 

dental apices, which also traverses the

 

 

pterygoid plate; palate is mobile, but

 

 

nasal complex is stable

616 Section III / Subspecialty Surgery

Le Fort II?

Le Fort III?

What is a “tripod” fracture?

Fracture through the frontal process of the maxilla, through the orbital floor and pterygoid plate; midface is mobile

Complete craniofacial separation; differs from II in that it extends through the nasofrontal suture and frontozygomatic sutures

Fracture of the zygomatic complex; involves four fractures:

1.Frontozygomatic suture

2.Inferior orbital rim

3.Zygomaticomaxillary suture

4.Zygomaticotemporal suture

Chapter 70 / Otolaryngology: Head and Neck Surgery 617

What is a “blowout” fracture? Orbital fracture with “blowout” of supporting bony structural support of orbital floor; patient has enophthalmos (sunken-in eyeball)

What is “entrapment”? Orbital fracture with “entrapment” of periorbital tissues within the fracture opening, including entrapment of extraocular muscles; loss of extraocular muscle mobility (e.g., lateral tracking) and diplopia (double vision)

What is a “step off”?

Fracture of the orbit with palpable “step off” of bony orbital rim (inferior or lateral)

Are mandibular fractures No; because the mandible forms an usually a single fracture? anatomic ring, 95% of mandible

fractures have more than one fracture site

What is the best x-ray study for mandibular fractures?

What must be ruled out and treated with a broken nose (nasal fracture)?

ENT WARD QUESTIONS

Panorex

Septal hematoma; must drain to remove chance of pressure-induced septal necrosis

How can otitis externa be

Otitis externa is characterized by severe

distinguished from otitis

pain upon manipulation of the auricle

media on examination?

 

What causes otitis media?

Most cases are caused by pneumococci

 

and H. influenzae

What causes otitis externa?

Pseudomonas aeruginosa

What must be considered in

Nasopharyngeal carcinoma

unilateral serous otitis?

 

What is the most common

Bell’s palsy, which has an unidentified

cause of facial paralysis?

etiology

618 Section III / Subspecialty Surgery

What is the single most important prognostic factor in Bell’s palsy?

What is the most common cause of parotid swelling?

What is Heerfordt’s syndrome?

Which systemic disease causes salivary gland stones?

What is the most common salivary gland site of stone formation?

Whether the affected muscles are completely paralyzed (if not, prognosis is95% complete recovery)

Mumps

Sarcoidosis with parotid enlargement, facial nerve paralysis, and uveitis

Gout

Submandibular gland

What is Mikulicz’s

Any cause of bilateral enlargement of the

syndrome?

parotid, lacrimal, and submandibular glands

What are the three major

1.

Airway protection

functions of the larynx?

2.

Airway/respiration

 

3.

Phonation

What is a cricothyroidotomy?

Emergent surgical airway by incising the

 

cricothyroid membrane

Name the four major

1.

Prolonged mechanical ventilation

indications for a

 

(usually 2 weeks)

tracheostomy.

2.

Upper airway obstruction

 

3.

Poor life-threatening pulmonary toilet

 

4.

Severe obstructive sleep apnea

What is a ranula?

Sublingual retention cyst arising from

 

sublingual salivary glands

What is Frey’s syndrome?

Flushing, pain, and diaphoresis in the

 

auriculotemporal nerve distribution

 

initiated by chewing

What causes Frey’s

Cutting the auriculotemporal nerve

syndrome?

causes abnormal regeneration of the

 

sympathetic/parasympathetic nerves,

 

which, once destined for the parotid

 

gland, find new targets in skin sweat

 

glands; thus, people sweat when eating

Chapter 70 / Otolaryngology: Head and Neck Surgery 619

What is the classic triad of Ménière’s disease?

What is the most common posterior fossa tumor and where is it located?

Hearing loss, tinnitus, vertigo (HTV)

Acoustic neuroma, usually occurring at the cerebellopontine angle

What is the most common

Maxillary sinus

site of sinus cancer?

 

What tumor arises from

Esthesioneuroblastoma

olfactory epithelium?

 

What cell type is most

Squamous cell

common in head and neck

 

cancer?

 

What are the most important predisposing factors to head and neck cancer?

Excessive alcohol use and tobacco abuse of any form

What is the most frequent site of salivary gland tumor?

What is the most common salivary gland neoplasm:

Benign?

Malignant?

What is the classic feature of croup?

What are the classic features of epiglottitis?

What comprises the workup of neck mass?

Parotid gland

Pleomorphic adenoma

Mucoepidermoid carcinoma

Barking, seal-like cough

“Hot-potato” voice, sitting up, drooling, toxic appearance, high fever, leaning forward

Do not biopsy; obtain tissue via FNA and complete head and neck examination
