Quality of life with functional pharyngeal preservation in advanced carcinomas of the base tongue complex using an integrated trimodality approach

Standard management of advanced carcinoma arising from the base of the tongue or infiltrating that region from contiguous areas (henceforth referred to as base of tongue complex [BTC] tumors) with radical surgery and postoperative radiation therapy results in extensive loss of function affecting deglutition, speech, and physical appearance. From January 1995, 16 patients with advanced stage BTC tumors were entered in this phase II study. Eleven patients (74%) had N2-3 neck disease. To optimize neck control, those with clinical N+ nodes at presentation had neck dissection. This was followed by hyperfractionated radiotherapy at 120 cGy twice daily to a median dose of 7,320 cGy to the primary and 6,240 cGy to areas with pathologically positive nodes. Concomitant chemotherapy was administered during weeks 1 and 4 of the radiation therapy using bolus cisplatin 75 to 100 mg/m2 on day 1 and continuous infusional 5-fluorouracil 750 to 1,000 mg/m2/d from days 1 to 4 of each chemotherapy cycle. Survival curves were plotted for various events, using actuarial life table methods. A functional assessment was made at least 1 year after completion of treatment using a previously validated Head/Neck Performance Status Scale. The median follow-up period was 23 months. There was a 100% complete response to the treatment at the primary site. The actuarial 4-year local (primary site) control was 100%, locoregional control (including nodes) was 69%, and disease-specific survival was 70% at 4 years. The predominant acute toxicity (63% incidence) was reversible grade III mucositis resulting in a median of 9 days' interruption in treatment. All of the patients were able to complete the prescribed treatment course, and there were no treatment-related deaths. Quality of Life assessment after treatment examined all facets of oropharyngeal function. Of note, none of the patients required long-term tube feedings. For the nine patients who responded to the functional assessment questionnaire, the results were excellent (score >75). The mean score for ability to eat in public was 75, mean of 76 for normalcy of diet, and 91 for understandability of speech. Concomitant hyperfractionated chemoradiation therapy produced excellent functional preservation with good long-term control in this patient group with historically poor prognosis. A 4-year actuarial local control rate of 69% was obtained, which is comparable to results of radical surgery and adjuvant radiation therapy. Further studies with modifications of fractionation and use of newer chemotherapy agents/radioprotectors will improve on these gains while reducing toxicity.

Endoscopic management of 108 sinus mucoceles

OBJECTIVES/BACKGROUND

Traditional teaching has emphasized the need for complete removal of sinus mucoceles to achieve a cure. However, with the introduction of endoscopic sinus surgical instruments and techniques, there has been a trend toward transnasal endoscopic management of sinus mucoceles. The aim of this study is to establish the efficacy of endoscopic management of sinus mucoceles.

STUDY DESIGN

Retrospective review.

PATIENTS AND METHODS

Between 1988 and 2000, 103 patients with 108 paranasal sinus mucoceles were treated endoscopically. This series includes 66 frontal and frontoethmoid, 17 ethmoid, 7 sphenoethmoid, 12 sphenoid, and 6 maxillary mucoceles. Ninety patients (83.3%) had intraorbital extension and 85 of them presented with some degree of proptosis or eye displacement. Sixty patients (55.5%) had erosion of the skull base with varying degrees of intracranial extension of the mucocele. Follow- up ranged from 1 to 131/2 years with a median of 4.6 years.

INTERVENTION

All patients underwent endoscopic-wide marsupialization of the mucocele cavity. Stents were used in frontal mucoceles only.

RESULTS

Recurrence of a frontal mucocele was seen in 1 patient (0.9%). In 5 patients, out of 23 patients who presented with massive pansinus polyposis in addition to the mucocele, recurrent polyposis required revision surgery. However, the mucoceles did not recur in those patients.

CONCLUSIONS

There is increasing evidence in the literature that endoscopic management of sinus mucoceles results in long-term control with recurrence rates at or close to 0%. Rhinologic surgeons should consider the endoscopic technique as the surgical treatment of choice.

Diabetes insipidus after pituitary surgery: incidence after traditional versus endoscopic transsphenoidal approaches

The endoscopic transnasal approach is gaining increasing popularity as the surgical method of choice for treatment of pituitary lesions. Previous studies have shown advantages such as quicker recovery and fewer cosmetic, dental, and nasal complications. However, no study has compared the rate of diabetes insipidus (DI) between the traditional and endoscopic approaches. This study will examine the incidence of short- and long-term postoperative DI after transnasal pituitary surgery and compare it with the incidence after traditional transseptal surgery. Eighty-one patients underwent transnasal surgery for the management of pituitary lesions. Fifty-five had the traditional sublabial, transseptal, transsphenoidal surgery and 26 patients had the direct transnasal, transsphenoidal endoscopic procedure. The incidence of immediate postoperative DI was 36% in the traditional group and 15% in the endoscopic group. Short-term (>2 weeks) DI that required treatment occurred in 11 patients (20%) in the traditional group and 2 patients (7.6%) in the endoscopic group. Long-term (>6 months) incidence of DI was 7.2% in the traditional group and 3.8% in the endoscopic group. We found a decreased incidence of immediate DI after transnasal endoscopic pituitary surgery as compared with the traditional sublabial transseptal approach. However, the incidence of long-term DI was not significantly different in the two groups.

Deep neck abscess: a retrospective review of 210 cases

This study was performed to review our experience with deep neck abscesses (DNAs) and compare it to the experiences in the available literature, and to study changing trends within our patient population. We retrospectively studied 210 patients who had DNAs between 1981 and 1998. Peritonsillar abscesses and limited intraoral abscesses were excluded. Demographics, presentation, etiology, site of abscess, associated systemic diseases, bacteriology, radiology, treatment, airway management, and outcome were reviewed. We compared the entire group to those in the available literature and studied changing trends within this patient population. Dental infection (43%) was the most common cause, followed by intravenous drug abuse (12%) and pharyngotonsillitis (6%). The incidences of intravenous drug abuse and mandibular fractures as causes of DNA were 19% and 8%, respectively, during the period 1981 to 1990, but were only 1% each during the period 1991 to 1998. Streptococcus viridans was the most common pathogen (39% of positive cultures), followed by Staphylococcus epidermidis (22%) and Staphylococcus aureus (22%). Lateral pharyngeal space abscess was the most common DNA (43%), followed by submandibular space abscess, Ludwig's angina, and retropharyngeal space abscess (28%, 17%, and 12%, respectively). Seventy-five percent of patients with true Ludwig's angina underwent tracheotomy. Nondental infections are no longer a significant etiologic factor in DNA. Streptococcus viridans has replaced S aureus and beta-hemolytic streptococci as the most common pathogen. Lateral pharyngeal space abscess was the most common DNA; however, its incidence has progressively decreased over the past decade. Intravenous drug abuse and mandibular fractures are no longer major etiologic factors. Tracheotomy is indicated in patients with Ludwig's angina.

Short-term and long-term quality of life after neck dissection

INTRODUCTION

Quality of life (QOL) is an important outcome measure in cancer therapy. Neck dissection (ND) morbidity has been well studied, but no study has focused on the quality of life after ND specifically.

METHODS

Fifty-one patients who have undergone ND completed a 6-item quality-of-life survey with a 7-point frequency and interference response scale. General QOL and comorbidity biases were evaluated with the SF-12 questionnaire and the Charlson comorbidity index.

RESULTS

The following symptoms were the most commonly experienced after surgery: neck tightness (71%), numbness or burning of the ear (57%), and shoulder discomfort (53%). However, interference with daily activities was reported by only 37%, 32%, and 33% of patients with these symptoms, respectively. Within 2 years of surgery, interference with daily activities decreased to 17%, 18%, and 12%, respectively. QOL after ND was negatively associated with previous radiation, previous chemotherapy, tumor stage, and more radical neck surgery but was positively associated with time after surgery. Shoulder discomfort and neck tightness had the greatest affect on QOL.

CONCLUSIONS

Our results suggest that patients should receive preoperative counseling regarding the morbidities from ND and the possible short-term and long-term impact on QOL. Further studies evaluating the relationship between primary tumor characteristics and quality of life after ND need to be undertaken.

A complete stylohyoid bone with a stylohyoid joint

Different clinical entities are associated with elongation of the styloid process or ossification of the stylohyoid ligament. Although partial ossification of the stylohyoid ligament is not uncommon, complete ossification is rare. We present a rare case of complete ossification of the stylohyoid ligament. This case may represent the extreme end of the spectrum of entities known as cervicopharyngeal pain syndrome, which includes Eagle's syndrome, stylohyoid syndrome, and pseudostylohyoid syndrome.

The role of endoscopic sinus surgery in chronic sinonasal sarcoidosis

The aim of this study was to define a role for endoscopic sinus surgery (ESS) in the treatment of chronic sinonasal sarcoidosis. All patients seen for sinonasal sarcoidosis in an otolaryngology practice in a tertiary care center from 1991 to 2000 were reviewed. Of 86 patients, 6 were treated with ESS for an operative rate of 7%. Surgeries were performed on those patients with significant sinonasal anatomic blockage. This included nasal obstruction from nasal polyposis and chronic and recurrent acute sinusitis from granulomatous lesions of the ostiomeatal complex. Patients remained symptom free for years after surgery on a nasal steroid regimen. Endoscopic sinus surgery is a viable treatment for those few patients with nasal obstruction or chronic sinusitis due to anatomic blockage from sinonasal sarcoidosis. Although it does not eradicate the disease or prevent recurrence, it does markedly improve quality of life by relieving severe symptoms and reducing the need for systemic steroids. This is the first study to advocate a role for surgery in sinonasal sarcoidosis beyond biopsy and management of complications. Although it may not be the appropriate approach for every patient, ESS certainly should be considered in the treatment options.

Intraoperative fabrication of palatal prosthesis for maxillary resection

BACKGROUND

Immediate placement of a palatal prosthesis has become the standard of care after maxillectomy or palatectomy, except when free-flap reconstruction is used. Palatal prostheses are usually fabricated preoperatively. Infrequently, the surgeon may face a situation where upper jaw resection has been performed and a prefabricated prosthesis is not available.

OBJECTIVE

To describe a method of rapid intraoperative fabrication of a palatal prosthesis, which allows immediate oral intake and excellent speech.

PROCEDURE

Two sheets of thermoplastic dressing (Aquaplast; WFR/Aquaplast Corporation, Wyckoff, NJ) were immersed in hot water. As they became soft and pliable, they were applied to the remaining hard palate and alveolar ridge. As the material cooled, it hardened, with its shape conforming to the remaining hard palate, alveolar ridge, and teeth. The rigid stent was then removed, trimmed, and fashioned to cover the palatal and maxillary defect. The stent was then wired to the remaining alveolar ridge and to the ipsilateral zygomatic buttress or lateral orbital rim. Removal of the stent was easily accomplished in an office setting.

PATIENTS

Twelve patients required partial upper jaw resection without available prefabricated prostheses. Of these, 3 patients underwent emergency surgery for mucormycosis and 2 for bleeding malignant tumors; 3 underwent bone resection more extensive than that anticipated preoperatively; and 4 did not have prefabricated prostheses for other reasons.

RESULTS

The thermoplastic prosthesis achieved its goals in all 12 patients. Eleven patients achieved oral food intake within 24 hours. One patient remained in a coma after extensive maxillary, orbital, and skull base resection for mucormycosis. The prosthesis was removed after 4 to 12 weeks and replaced with a permanent implant in 11 of the 12 patients.

CONCLUSIONS

This simple, quick, and inexpensive intraoperative fabrication of palatal prosthesis requires no special expertise and equipment. It allows immediate oral intake and excellent speech.

Quality of life after great auricular nerve sacrifice during parotidectomy

OBJECTIVE

To determine the impact of great auricular nerve (GAN) sacrifice during parotidectomy on patients' quality of life.

DESIGN

Historical cohort survey of patients who had undergone GAN sacrifice during parotidectomy.

SETTING

Tertiary academic otolaryngologic practice.

PATIENTS AND METHODS

Fifty-three patients who had undergone GAN sacrifice during parotidectomy completed an 8-item quality-of-life survey with a 7-point response scale designed to measure outcome after GAN sacrifice during parotidectomy.

RESULTS

Thirty patients (57%) reported experiencing at least 1 abnormal symptom, but the mean number of symptoms decreased significantly with time, from a mean of 2.3 during the first year to 0.2 after 5 years (P<.001). Even among patients experiencing symptoms, 23 (77%) reported only a little or no bother caused by the symptoms, and 27 (90%) reported no interference or almost none with their daily activities. The degree of bother or interference reported had a moderate positive correlation with the number of abnormal sensations reported.

CONCLUSIONS

The results suggest that, while many patients experienced sensory deficits, the overall quality of life was not significantly affected after GAN sacrifice during parotidectomy. Patients who report multiple abnormal sensations, however, would benefit from additional counseling and from reassurance that the number of sensations will diminish with time. Further study evaluating the effect of preservation of the posterior branch of the GAN during parotidectomy on patients' quality of life is needed.

Powered instrumentation for transcervical removal of gigantic intrathoracic thyroid

BACKGROUND

It is widely accepted that almost all intrathoracic goiters can be removed through the neck. For those rare gigantic goiters that cannot be removed transcervically, median sternotomy is usually recommended. During the last 11 years we used intracapsular volume reduction techniques to facilitate transcervical removal of extremely large intrathoracic goiters. Materials and Methods Of 149 patients with intrathoracic goiters, 11 patients had gigantic lesions that could not be removed transcervically. Instead of sternotomy, we used the arthroscopic or sinus microdebrider or a large-bore suction device for controlled intracapsular volume reduction. This was followed by complete removal of the gland through the neck.

RESULTS

The thyroid gland was removed completely in all 11 patients. None of the patients had any evidence of intraoperative spillage of thyroid tissue. No major complications were noted.

CONCLUSIONS

We have found the use of the microdebrider and/or suction device for intracapsular volume reduction to be extremely helpful for transcervical removal of gigantic intrathoracic goiters.

Frontal sinus obliteration with the pericranial flap

BACKGROUND

Frontal sinus obliteration is often accomplished by autologous grafts such as fat, muscle, or bone. These avascular grafts carry an increased risk of resorption and infection as well as donor site morbidity. Vascular regional flaps may be used to obliterate small sinuses with less morbidity.

OBJECTIVES

To review our experience with the use of the pericranial flap for obliteration of the frontal sinus.

METHODS

The records of 10 patients who underwent obliteration of the frontal sinus with the pericranial flap were reviewed. Demographics, indications for frontal sinus obliteration, immediate and late complications, and long-term outcome were recorded. These results were compared with those in the current literature.

RESULTS

Ten sinuses were obliterated with the pericranial flap. Indications included frontal sinus mucocele, mucopyocele, frontal sinus osteomyelitis, and frontal sinus fracture. The median follow-up was 3 years. There was 1 short-term complication of persistent headache for 1 month, and there was asymptomatic recurrence of a neofrontal sinus in 1 case.

CONCLUSIONS

The pericranial flap is a vascularized local flap that is easily harvested. The use of the pericranial flap avoids donor site morbidity associated with free fat or cancellous bone grafts. The pericranial flap arms the head and neck surgeon with an effective alternative to other methods of frontal sinus obliteration.

The superior turbinectomy approach to isolated sphenoid sinus disease and to the sella turcica

Sphenoidotomy or sphenoidectomy are most commonly performed as part of a more extensive pansinus procedure. However, rhinologists may find themselves occasionally in a need to surgically treat an isolated sphenoid sinus disease. With the introduction of endoscopic sinus techniques and instrumentation, intranasal sphenoidotomy has become increasingly popular. The most common approach used is the intranasal, transethmoid sphenoidectomy. Alternatively, many surgeons perform middle turbinectomy to approach the sphenoid sinus transnasally. We describe our direct transnasal, nontransethmoid, nontransseptal approach to the sphenoid sinus. Superior tubinectomy is performed to enhance the exposure of the anterior sphenoid wall. Seventy patients underwent sphenoid sinus exploration for isolation sphenoid sinus disease or for pituitary lesions. Surgical goals were achieved in all patients and there were no complications related to the technique. The superior turbinectomy approach to isolated sphenoid sinus disease provides excellent exposure and avoids the sequelae of total ethmoidectomy or middle turbinectomy.

Transnasal endoscopic management of frontal mucoceles

Traditional teaching has emphasized the need for complete removal of sinus mucocele to achieve a cure. With the introduction of endoscopic sinus surgical instruments and techniques, however, there has been a trend toward transnasal endoscopic management of frontal mucoceles with recurrence rates at or close to 0%. This article presents a useful classification of frontal mucoceles and the transnasal endoscopic surgical technique.

The role of fiberoptic nasopharyngoscopy in the management of the acute airway in angioneurotic edema

BACKGROUND

Angioneurotic edema of the upper aerodigestive tract (AEUAT) often challenges the otolaryngologist with the decision of surgical intervention versus observation.

OBJECTIVE

To develop a logical approach to the evaluation and management of the airway in patients with AEUAT, emphasizing fiberoptic examination (FOE) findings.

METHODS

A computer-based retrospective review of all patients diagnosed with AEUAT was performed. The charts were reviewed for demographics, etiology, medical history, presentation, physical examination, imaging studies, intervention, and outcome. Findings on FOE as well as other covariants were statistically compared.

RESULTS

Seventy patients with AEUAT were identified. The etiologies consisted of 24 cases of angiotensin converting enzyme inhibitor use (33%), 10 allergic reactions (17%), 1 hereditary (1.5%), and 35 idiopathic cases (48%). Fourteen patients underwent airway intervention, including 6 tracheotomies and 8 intubations. Of the 14 patients, 5 underwent emergent intervention before fiberoptic examination, 4 had laryngeal edema only, and 5 had both laryngeal and base of tongue edema. No patients with both laryngeal and base of tongue edema were observed. The remaining 52 patients were observed in a monitored setting and required no subsequent intervention.

CONCLUSION

FOE is an invaluable tool in the assessment of the compromised airway in patients with angioneurotic edema Laryngeal edema alone is an ominous physical finding. When laryngeal and pharyngeal edema are present together, the physician should consider immediate intervention. Our findings indicate that symptoms, including stridor, hoarseness, and dysphagia, do correlate with disease severity; however, they must be confirmed with fiberoptic visualization. Although sound clinical judgment should always be exercised, we present our results in the management of the acute airway in angioneurotic edema.

Unilateral pulmonary agenesis presenting as an airway lesion

Otolaryngologists are frequently consulted to perform rigid bronchosopy in children with suspected foreign body aspiration, mucous plug occlusion of a mainstem or lobar bronchus, or other bronchial mass lesions. Chest radiographs that demonstrate unilateral lung or lobar collapse with a shift of mediastinal structures toward the affected side often prompt this referral. We describe 2 children, one with unilateral pulmonary agenesis and one with pulmonary aplasia, who presented with these radiologic findings. In each case, the definitive diagnosis was made at the time of bronchosopy. The diagnosis might have been suspected preoperatively if the chest radiographs had been reviewed with this clinical entity in mind. Because of its variable clinical presentation, diagnosis requires a high index of suspicion. Although computed tomography of the chest is diagnostic, the diagnosis may be suggested by chronic changes in the contralateral aspect of the chest wall and lung expansion on chest radiographs. Misdiagnosis may subject the patient to the unnecessary risks of bronchoscopy and to potential perforation of the rudimentary bronchus. Although pulmonary agenesis is a rare entity, it may mimic more common airway lesions. Therefore, unilateral pulmonary agenesis should be considered in the differential diagnosis of pediatric airway lesions. Arch Otolaryngol Head Neck Surg. 2000;126:1386-1389

Retropharyngeal abscess secondary to penetrating foreign bodies

A retrospective study was conducted on patients with upper aerodigestive tract foreign bodies requiring operative intervention over a 12-year period to aid in the recognition and management of foreign body associated complications. Oesophagoscopies were performed for the removal of foreign bodies in 37 patients, age one to 82 years with a male to female ratio of 1.2:1. Retropharyngeal abscesses accounted for eight of 11 foreign body-associated complications. Fish bones were the cause in six cases, chicken bone and a pen refill in one case each. An abscess was already present at the time of initial procedure in six cases and developed in two cases after successful removal of the foreign body. A high level of suspicion for a retropharyngeal abscess should be maintained in cases with perforation, and in patients with immunodeficiency.

Transcranial magnetic stimulation in acute facial nerve injury

OBJECTIVE/HYPOTHESIS

Available electrodiagnostic tests that are used to evaluate facial nerve injury examine the nerve distal to the stylomastoid foramen; because most facial nerve injuries are within the temporal bone, the tests cannot evaluate the nerve at or across the injury site. The interpretation of these tests depends on the predictability (or unpredictability) of distal degenerative process. Transcranial magnetic stimulation may be able to stimulate the nerve proximal to the injury site. The hypothesis of the present study is that in cases of mild traumatic facial nerve injury where axonal integrity is maintained, proximal stimulation of the nerve using higher than normal stimulus intensities to "overcome" the block at the injury site result in recordable facial nerve activity.

STUDY DESIGN

A prospective controlled animal study comparing response to transcranial magnetic stimulation of the facial nerve in the following groups: mild injury, severe injury/transection, and control.

METHODS

We studied 44 facial nerves in 22 cats. Fifteen nerves were subjected to mild trauma. Five nerves were severely crushed, 2 nerves were completely transected, and 22 nerves were not traumatized. All nerves were examined with the transcranial magnetic stimulation system before the trauma, immediately after the trauma, and at 3, 8, and 12 weeks after trauma.

RESULTS

All nerves in the mild and severe trauma groups showed complete clinical paralysis immediately after trauma. The nerves in the mild trauma group showed significant increase in threshold as well as significant increase in latency for recordable facial muscle response to transcranial magnetic stimulation. Thresholds and latencies decreased gradually within 3 to 12 weeks and returned almost to preinjury levels. This paralleled the return of clinical facial muscle movement. In the severe trauma/transection group, the nerves had no facial muscle response to transcranial magnetic stimulation after trauma. Neither facial muscle response to transcranial magnetic stimulation nor facial muscle movements recovered.

CONCLUSIONS

In cats transcranial magnetic stimulation can assess the integrity of the facial nerve after trauma and predict its potential for regeneration. This technique can excite the nerve proximal to the injury site and may play a role in the clinical evaluation of the acute traumatic facial nerve paralysis. It can be used immediately after trauma, because it does not depend on wallerian degeneration to occur.

Is there a correlation between radiographic and histologic findings in chronic sinusitis?

OBJECTIVE

To determine if the degree of radiologic changes noted on computed tomography (CT) scan correlate with the severity of histologic changes.

DESIGN

Retrospective analysis.

SETTING

Academic tertiary care centre.

METHODS

Sixty consecutive patients undergoing endoscopic sinus surgery for chronic sinusitis, with complete data obtained for 131 sinuses.

MAIN OUTCOME MEASURES

Paranasal sinus CT scans and pathologic reports were examined. Respective findings were graded as mild, moderate, or severe, and the results were analyzed for agreement. CT scan grading was based on the extent of sinus opacification and pathologic grading was determined by the number of inflammatory cells found in the sinus mucosa.

RESULTS

Of the 51 ethmoid sinuses, agreement between the radiographic and histologic grading occurred in 32 or 62.7%. In the maxillary group, a 57.1% (24 of 42) correlation was noted. Of the 20 frontal sinuses, agreement occurred in 8 or 40%, whereas a 22.2% (4 of 18) correlation was present in the sphenoid group.

CONCLUSION

This study suggests that the severity of sinus disease based on preoperative CT scan does not correlate with the histologic degree of disease.

Alterations in head and neck cancer occurring in HIV-infected patients--results of a pilot, longitudinal, prospective study

To assess the impact of human immunodeficiency virus (HIV) infection on the presentation and course of head and neck squamous cell carcinoma (HNSCC), we performed a pilot, prospective, longitudinal study of all patients with HNSCC presenting to our institutions over a 6-month period (n = 10). A 60% incidence of HIV infection was seen in this study population, with SCC presenting as the initial manifestation of HIV infection in 2 of the 6 patients. In addition. HIV-infected patients were significantly younger than non-infected patients at (p = 0.01). None of the HIV-infected patients had acquired immunodeficiency syndrome (AIDS) at the time of presentation, but 5 of 6 patients had an abnormal CD4 count, compared to none of the non-infected patients (p = 0.05). The absolute CD4 count in HIV-infected patients decreased to less than 100x10(9)/L in the majority of these patients within 3 months of presentation with HNSCC (p = 0.05). Treatment-associated complications were common in HIV-infected patients, occurring in 4 of the 6 cases in contrast to none of the patients without HIV infection (p = 0.046). Outcome was significantly poorer for HIV-Infected patients, with 5 patients succumbing to their disease within one year, in contrast to none of the non-infected patients (p = 0.046). These data, combined with our previous work, justify further investigation of the relationship between HNSCC and HIV infection and the possibility of its inclusion as an AIDS-defining process.

Head and neck manifestations of non-Hodgkin's lymphoma in human immunodeficiency virus-infected patients

PURPOSE

Non-Hodgkin's lymphoma is the 2nd most common malignancy in human immunodeficiency virus (HIV)-infected patients. However, limited information regarding head and neck manifestations of non-Hodgkin's lymphoma is present in the literature. The aim of this article is to describe the head and neck manifestations of non-Hodgkin's lymphoma in HIV-infected patients and compare it with that seen in noninfected patients.

PATIENTS AND METHODS

A case-control study was performed including 124 patients with non-Hodgkin's lymphoma presenting over a 5.5-year period to tertiary care center in a metropolitan location.

RESULTS

Overall, the anatomic distribution of non-Hodgkin's lymphoma is not altered in the presence of HIV infection with the head and neck region (63%) most often involved overall. However, within the head and neck region, extralymphatic disease is significantly more common in HIV-infected patients (59%) than noninfected patients (33%; P = .001). Central nervous system (CNS) involvement accounts for 41% of head and neck non-Hodgkin's lymphoma in HIV-infected patients, in contrast to only 12% of noninfected patients. High-grade lymphoma (68%) are more common than intermediate (30%) or low-grade disease (2%) in the HIV-infected population, whereas low (24%) and intermediate (60%) grades are more common than high-grade lymphoma (16%) in noninfected patients (P < .001). The large cell immunoblastic type (48%) is the most common subtype in HIV-infected patients, whereas diffuse large-cell type (32%) was most common in HIV-negative patients (P < .05). Survival is significantly poor for HIV-infected patients (P < .05). The impact of HIV infection on survival remain significant even after controlling for the effects of confounding factors.

CONCLUSIONS

Head and neck involvement with non-Hodgkin's lymphoma occurs in a significant number of HIV-infected patients. Our data show that the distribution and course of non-Hodgkin's lymphoma is unique in HIV-infected patients. A high level of suspicion for non-Hodgkin's lymphoma is required in all cases of head and neck lesions in patients with HIV infection to facilitate management.

Ten-year experience with cervical miniesophagostomy

This report describes our experience with 35 patients who underwent intraoperative transcutaneous cervical miniesophagostomy (TCME) during conservation laryngeal and/or hypopharyngeal surgery. The TCME was designed to provide enteral alimentation without the need for a nasogastric tube. Nasogastric tubes may cause posterior laryngeal inflammation, granulations, muscle damage, and vocal cord immobility. Friction between nasogastric and tracheotomy tubes may result in damage to the remaining posterior larynx and may delay healing, oral feeding, and decannulation. Percutaneous endoscopic or radiologically assisted gastrostomy is a possible solution. However, it requires time, special expertise, and coordination with other specialties. In addition, immediate and delayed abdominal complications may occur. The TCME is a relatively simple and quick procedure that is performed during the primary cancer surgery by the head and neck surgeon. It requires no special equipment. It takes about 5 minutes to perform and, if done correctly with tunneling under the skin flaps, is associated with minimal or no postoperative morbidity. It is useful after supraglottic laryngectomy, partial laryngectomy, partial laryngopharyngectomy, and base of tongue resection, and in selected cases of vertical hemilaryngectomy and anterolateral laryngectomy. In the last group, we found that TCME is required if the arytenoid cartilage is removed and the posterior aspect of the larynx is disrupted. There were only minor complications related to TCME. Leakage from the miniesophagostomy did not occur, primarily because of the superior-to-inferior orientation of the tube and the long subplatysmal tunneling before esophageal entrance.

Latissimus dorsi myocutaneous flap for secondary head and neck reconstruction

PURPOSE

To review our experience and results with the use of pedicled latissimus dorsi myocutaneous flap (LDMF) for secondary reconstruction in head and neck surgery.

METHODS

Twenty-two patients had LDMF, 17 of them for secondary reconstruction. Data were collected regarding the primary surgery, primary method of reconstruction, indication for secondary reconstruction, and outcome.

RESULTS

Seventeen LDMF procedures were performed for secondary reconstruction. Flap success rate was 100%. Reconstructive goals were achieved immediately in 16 (94.1%) patients.

CONCLUSION

LDMF is a thin flap with a large surface area and a long pedicle that allows it to reach any region in the head, neck, and scalp. Its main disadvantages are the need for lateral positioning of the patient and the fact that its pedicle is not protected with muscle. In our experience, LDMF provides an excellent reconstructive option especially in complicated cases of secondary reconstruction. It may be used in cases where a free flap is usually used, but with significantly reduced surgical time.

Presentation, course, and outcome of head and neck skin cancer in African Americans: a case-control study

BACKGROUND

Several reports have shown that the presentation, course, and outcome of skin cancer is altered in African Americans. Subset data from these studies suggest that the course of head and neck skin cancer may be different from that occurring in other sites. However, very few studies have specifically investigated skin cancer involving the head and neck region in African-American patients.

METHODS

Retrospective case-control study including 215 patients with skin cancer (squamous cell carcinoma [SCC], basal cell carcinoma [BCC], malignant melanoma, and adnexal tumors) presenting to a tertiary care institution over a 9.5-year period. Cases were defined as African Americans with skin cancer, and the control group included white and Latin-American patients with skin cancer.

RESULTS

Skin cancer occurred in the head and neck region in 135 cases (62%). However, head and neck involvement was less common in African-American patients (44%) than the control group (76%; P < .001). The anatomic distribution of head and neck skin lesions was similar between the groups, with nasal and scalp skin most often involved. In the head and neck region, the ratio of BCC to SCC (4:1) was similar among all groups. In contrast, in non-sun-exposed regions, the ratio was 1:8.5 for African-American patients compared with 1:1 for the control group (P < .001). The overall distribution of malignant melanoma was not influenced by sun exposure in either groups. The study groups were similar in gender distribution, primary treatment modality, rates of positive margins, and development of second skin cancers. Although African Americans presented with more advanced lesions (P < .001), their disease-free interval was similar to the control group. Only the margin status was a significant predictor of disease-free survival by multivariate analysis, with a relative risk of 1.68 (95% CI: 1.58-18.24)

CONCLUSIONS

Head and neck skin cancer is similar with regard to presentation and distribution in patients of all skin types. Moreover, in contrast to previous reports, the course of head and neck skin cancer may be less aggressive in African Americans, if appropriate treatment is provided. This report suggests that differences in skin cancer in African Americans reported in the literature reflect cancer occurring in non-sun-exposed regions.

Isolated cervical tuberculosis in patients with HIV infection

OBJECTIVE

Tuberculosis isolated to the head and neck region is common in patients with HIV infection. However, the management of isolated head and neck tuberculosis has not been reported in the literature. This study was done to describe the characteristics of tuberculosis isolated to the head and neck region in patients infected with HIV and to detect differences in presentation and diagnostic management based on the status of HIV infection at presentation.

METHODS

A retrospective study was performed including 38 patients infected with HIV who were seen with tuberculosis isolated to the head and neck region at two tertiary care centers during a 10-year period. These patients were divided into two groups on the basis of the HIV status at presentation, which indirectly reflects the level of immunosuppression. Group 1 included 11 patients (29%) with AIDS at presentation. Group 2 included 27 patients (71%) with HIV infection but not AIDS.

RESULTS

The cervical lymphatics were the most common site for isolated head and neck tuberculosis (89%), with the supraclavicular nodes most often involved (53%). Extralymphatic involvement was less common (11%), but involved a variety of anatomic locations (skin, spinal cord, larynx, parotid). The presenting history and physical examination had a low sensitivity for tuberculosis in patients with HIV infection, mainly because of the presence of multiple confounding factors. Purified protein derivative testing was highly sensitive for tuberculosis in patients with HIV infection alone (61 %); however, its usefulness was diminished in patients with AIDS (14%; p=0.03). Fine-needle aspiration biopsy was 94% sensitive for diagnosing tuberculosis and was not affected by the status of HIV infection. Surgical biopsy was the gold standard for diagnosing tuberculosis but was associated with chronically draining fistulas in a significant number of cases (14%).

CONCLUSIONS

These data suggest that tuberculosis should be considered in the differential diagnosis of all head and neck lesions in patients infected with HIV, even in the absence of pulmonary involvement. Purified protein derivative testing should be done liberally in these patients, with realization that the sensitivity of purified protein derivative testing is reduced in patients with AIDS. Fine-needle aspiration biopsy should be the key diagnostic test in this patient population, with open surgical biopsy reserved for highly suspicious cases in which other measures were not diagnostic.

Branchial cleft cyst carcinoma: myth or reality?

Skepticism has surrounded the existence of branchial cleft carcinoma since the entity was first described in 1882. However, a landmark work of 1950 established four criteria for the diagnosis of branchial cleft carcinoma, the most important criterion being histologic proof of carcinoma arising from a normal cyst epithelium. Of the 43 cases found in an extensive review of the literature, only 7 cases have satisfied all four of the criteria. To this we add 2 patients who had recurrent infections of a cervical cyst as children and later developed carcinoma within these structures. Additionally, we propose a minor modification to the 1950 criteria and a paradigm for diagnosis and management of these lesions.

Pediatric temporal bone fractures

OBJECTIVE

To examine the etiology, presentation, and management of temporal bone fractures in children.

STUDY DESIGN

Case control.

METHOD

Retrospective review of a level I pediatric trauma center from July 1, 1990 to November 1, 1996 identified 680 patients. Inclusion criteria of age less than 14 years and only blunt temporal bone trauma identified 122 patients, with 97 charts available for review. The criteria for temporal bone fracture consisted of both clinical and radiologic information. Only patients with temporal bone fractures confirmed by computed tomography, a complete otolaryngology examination, and audiometric evaluations were included in the study. The data were analyzed with the Kruskal-Wallis analysis of variance (ANOVA) for examining the three separate age groups of fractures. Chi-squared analysis was used to compare these data with previously published adult and pediatric temporal bone fracture series and to examine the three separate age groups of fractures.

RESULTS

The review identified 72 children with 79 temporal bone fractures: 47 boys and 25 girls. The patients ranged from 6 months to 14 years of age, with a bimodal distribution of patients with peaks at 3 years and 12 years of age. The most common causes of fractures were motor vehicle accidents (47%), falls (40%), biking accidents (8%), and blows to the head (7%). Common presenting signs and symptoms included hearing loss (82%), hemotympanum (81%), loss of consciousness (63%), intracranial injuries (58%), bloody otorrhea (58%), extremity fractures (8%), and facial nerve weakness (3%). The most common causes of temporal bone fractures were falls and motor vehicle accidents. Forty-two patients were noted to have bloody otorrhea and possible cerebrospinal fluid leak. Twenty-four received intravenous antibiotics. No patient developed prolonged otorrhea or meningitis during hospitalization and the follow-up period. The classification of fracture patterns was longitudinal, 54%; transverse, 6%; oblique, 10%; squamous, 27%; and other, 3%. Hearing loss was found in 59 patients, with conductive hearing loss being the most common finding in 56% of the patients, followed by sensorineural hearing loss in 17% and mixed hearing loss in 10%.

CONCLUSIONS

Pediatric temporal bone fractures are associated with falls and motor vehicle accidents. There is a high incidence of associated intracranial injuries and hearing loss, but facial nerve injuries are uncommon. Timely management minimizes complications.

Impact of comorbidity on outcome of young patients with head and neck squamous cell carcinoma

BACKGROUND

Comorbid conditions have a significant impact on the actuarial survival of patients with head and neck cancer. However, no studies have evaluated the impact of comorbidity on tumor- and treatment-specific outcomes. This study was performed to evaluate the impact of comorbidity, graded by the Kaplan-Feinstein comorbidity index (KFI) on the incidence and severity of complications, disease-free interval, and tumor-specific survival in patients undergoing curative treatment for head and neck cancer.

METHODS

A multi-institutional, retrospective cohort of 70 patients 45 years of age and under with head and neck squamous cell carcinoma (SCC) presenting over an 11-year period was studied.

RESULTS

Advanced comorbidity (KFI grade 2 or 3) was present in 21 patients (30%). Patients with advanced comorbidity did not differ from patients with low-level comorbidity (KFI grades 0 or 1) in sex distribution, race, presence of human immunodeficiency virus (HIV) infection, tobacco use, location of primary lesion, stage at presentation, pathologic differentiation of the tumor, or type of initial treatment. The overall incidence of treatment-associated complications was similar between the groups (57% versus 49%; p > 0.05), but a higher proportion of patients with advanced comorbidity developed high-grade complications (24% versus 6%; p = .04). The median disease-free interval (11.1 months versus 21.6 months; p = .045) and tumor-specific survival (13.7 months versus 57.6 months; p = .03) was poorer for patients with advanced comorbidity. The effects of comorbidity on survival remained significant even after adjusting for the confounding effects of HIV status and tumor stage (p = .05).

CONCLUSIONS

The presence of comorbid conditions has a significant impact on tumor- and treatment-specific outcomes. Although the presence of advanced comorbid conditions is not associated with an increase in the rate of treatment-associated complications, complications tend to be more severe in this population. More importantly, advanced comorbidity has a detrimental effect on the disease-free interval and tumor-specific survival in patients with head and neck cancer, independent of other factors. This suggests that comorbidity may impact on tumor behavior, presumably by altering the host's response to cancer. Accordingly, to be more predictive and reliable, the current staging system for head and neck cancer should include a description of the patient's comorbidity.

Sinus mucoceles: is marsupialization enough?

Traditional teaching in the United States has emphasized the need for complete removal of sinus mucoceles to achieve a cure. In Europe, however, many rhinologic surgeons have been treating sinus mucoceles by draining and marsupializing them. We present our experience with the treatment of 16 patients with sinus mucoceles. This series includes nine frontal, two ethmoid, two sphenoid, one sphenoethmoid, and two maxillary sinus mucoceles. All patients were treated transnasally under telescopic control. All mucoceles were marsupialized, and 11 were stented. Intraoperative transillumination as well as intraoperative lateral x rays (for sphenoethmoid lesions) and anteroposterior x rays (for frontal mucoceles) were used to ensure complete marsupialization of the lesion and to confirm proper placement of the stent. There were no complications associated with the procedure. Follow-up periods ranged from 8 to 62 months (median, 32 months). No evidence of recurrent mucocele has been seen in any of the patients.

Validation of the Charlson comorbidity index in patients with head and neck cancer: a multi-institutional study

Comorbid conditions are medical illnesses that accompany cancer. The impact of these conditions on the outcome of patients with head and neck cancer is well established. However, all of the comorbidity studies in patients with head and neck cancer reported in the literature have been performed using the Kaplan-Feinstein index (KFI), which may be too complicated for routine use. This study was performed to introduce and validate the use of the Charlson comorbidity index (CI) in patients with head and neck cancer and to compare it with the Kaplan-Feinstein comorbidity index for accuracy and ease of use. Study design was a retrospective cohort study. The study population was drawn for three academic tertiary care centers and included 88 patients 45 years of age and under who underwent curative treatment for head and neck cancer. All patients were staged by the KFI and the CI for comorbidity and divided into two groups based on the comorbidity severity staging. Group 1 included patients with advanced comorbidity (stages 2 or 3), and group 2 included those with low-level comorbidity (stages 0 or 1). Outcomes were compared based on these divisions. The KFI was successfully applied to 80% of this study population, and the CI was successfully applied in all cases (P < 0.0001). In addition, the KFI was found to be more difficult to use than the CI (P < 0.0001). However, both indices independently predicted the tumor-specific survival (P = 0.007), even after adjusting for the confounding effects of TNM stage by multivariate analysis. Overall, the CI was found to be a valid prognostic indicator in patients with head and neck cancer. In addition, because comorbidity staging by the CI independently predicted survival, was easier to use, and more readily applied, it may be better suited for use for retrospective comorbidity studies.

Cervical necrotizing fasciitis

Cervical necrotizing fasciitis (CNF) is an aggressive infection of the head and neck with high complication and mortality rates. Sixty-eight cases of CNF have been reported in the English-language literature. We present a series of 8 patients with CNF, including 5 men and 3 women ranging in age from 25 to 92 years. To the best of our knowledge, this is one of the largest case series reported. Six of the 8 patients had a predisposing odontogenic focus of infection. Four patients had mediastinal involvement. Two patients, both with significant comorbidity at the time of presentation, died of CNF.

Concomitant infusion cisplatin and hyperfractionated radiotherapy for locally advanced nasopharyngeal and paranasal sinus tumors

PURPOSE

This is a prospective study to improve the therapeutic ratio in the treatment of patients with locally advanced nasopharyngeal and paranasal sinus tumors by using split-course concomitant infusion cisplatin chemotherapy and hyperfractionated radiotherapy.

METHODS AND MATERIALS

From 1983 to 1993, 21 patients with locally advanced nasopharyngeal and paranasal sinus tumors (T3 and T4, or recurrent tumors involving the facial bones and/or the base of the skull) were treated with a regimen of split-course hyperfractioned radiotherapy (1.2 Gy/fraction/bid) and concomitant infusion cisplatin (5-10 mg/m2/24 h). The therapy was given in three separate 2-week sessions with 1 to 2 week breaks between sessions. Seventeen of 21 patients were treated with curative intent with cumulative radiation doses ranging from 64.8 to 70.8 Gy. Four patients were treated with palliative intent to a total dose of less than 60 Gy or to a limited field due to previous irradiation.

RESULTS

Sixteen of 17 patients (94%) treated curatively achieved a complete response. Of the 16 patients who achieved complete response, 7 patients (50%) were alive at the time of analysis (36 to 126 months). One patient was alive at 4 years with no evidence of disease, and died in 10 years at the age of 80 of unknown cause. Two patients died of local recurrence at 21 and 45 months and one patient died of a cerebrovascular accident at 12 months with disease status unknown. Five patients died of distant metastases. The one patient who had a partial response died in 25 months with local disease and metastases to the bone and lung. Four patients that were previously irradiated received a reduced total dose or treated to a limited irradiation field. All had near complete responses, but died within a year of treatment, with the exception of one patient who died at 23 months. Acute reactions included intense erythema of the mucosa in all patients. Five of 21 (23%) developed punctate mucositis and 3 of 21 (14%) developed confluent mucositis. Hematologically, one patient developed neutropenia (1800 WBC/mm3) and one developed thrombocytopenia (38,000/mm3). A rising creatinine was observed in three patients (2.0, 1.7, 1.7) all of whom were treated with the higher 10 mg/m2/day dose of infusional cisplatin. In all three of these cases, the creatinine slowly returned to normal over a 6-month period. Hormonal evaluations were performed in three patients and all were within normal ranges. There was no evidence of neck fibrosis or trismus. One patient with gross recurrent disease of the orbit developed blindness of the involved eye due to corneal opacification. The orbital area had been reirradiated in this patient.

CONCLUSIONS

Concomitant infusion cisplatinum with hyperfractionated radiation improved tumor control, but did not increase normal tissue injury. Acute reactions were minimized by splitting the treatment with a 1- to 2-week break after each 2 weeks of radiation treatment. Late complications were not increased by using a hyperfractionated radiation regimen. The local failure rate was only 18% (3 of 17 patients), but the distant failure rate was 35% (6 patients). Further investigation is needed to prove if adjuvant chemotherapy after concomitant chemoradiation improves survival by decreasing the distant failure in such advanced cases.

Swallowing and pharyngeal function in postoperative pharyngeal cancer patients

This study examines the pharyngeal phase of swallowing after the resection of pharyngeal cancer, and focuses on the pharynx as a functional organ. The purpose of the study was to obtain information on both reconstruction and rehabilitation in cases of surgically treated pharyngeal cancer. The records of 21 consecutive patients who underwent surgical treatment of oropharyngeal and hypopharyngeal squamous cell carcinoma between 1990 and 1993 were reviewed. Functional results following surgery were graded on a numerical scale in three categories: pharyngeal swallow, laryngeal and lower airway protection, and oral alimentation. Three treatment groups were observed: group 1 = transoral excision with primary closure (six patients); group 2 = composite resection with primary closure (nine patients); and group 3 = composite resection with deltopectoral or pectoralis major flap closure (six patients). Comparison of pharyngeal swallow and laryngeal protection functions showed no significant difference between the three groups. However, oral alimentation performance in group 1 was significantly better than in group 3, and groups 1 and 2 achieved a similar level. In patients with T3 and T4 tumors postoperative function was poor and no difference in postoperative function was demonstrated between patients undergoing reconstruction with primary closure and patients undergoing reconstruction with deltopectoral or pectoralis major flaps. Patients with T3 and T4 tumors experienced impaired postoperative function regardless of the method of reconstruction used. This is not a condemnation of the surgical treatment of advanced pharyngeal tumors, but rather a suggestion that other reconstruction techniques be considered.

Frontal sinus outflow anatomy

Most of the studies of frontal sinus anatomy were completed 50 to 70 years ago. The information they provide is not necessarily relevant or helpful to the modern rhinologic surgeon who approaches the frontal sinus transnasally and endoscopically. We performed anatomical dissections of the outflow tract of 82 frontal sinuses in 41 cadaver heads to illustrate the various drainage patterns from the frontal sinus to the nose and to correlate these drainage sites with the distance and angle from the pyriform aperture. We found that the frontal sinus drained anterior to the uncinate process in 24 specimens (29.3%) with an average distance of 3.65 cm from the pyriform aperture and 58 degrees from the nasal floor. The frontal sinus drained posterior to the uncinate process in 56 specimens (68.3%) with an average distance of 4.10 cm and 65 degrees from the nasal floor. In this latter group, most of the sinuses (51 specimens) drained into the ethmoid infundibulum. Two of the specimens had a hypoplastic frontal sinus with no outflow tract at all. These findings are different from those described in the early 20th century.

Complications associated with 327 foreign bodies of the pharynx, larynx, and esophagus

We intended to identify the types and incidence of complications associated with foreign bodies (FBs) impacted in the upper aerodigestive tract (UADT) and to ascertain factors predisposing to the development of these complications. The design was a retrospective cohort study of 327 patients with UADT foreign bodies admitted to a tertiary care center. The overall incidence (7.6%) and types of complications varied by age. Complications developed in 4.8% of 208 patients 10 years of age and under, with pulmonary complications being most common. In contrast, complications occurred in 12.6% of 119 older patients, with retropharyngeal abscess being the most common (p < .0001). Delayed presentation (> 24 hours after the onset of symptoms) was the only factor associated with an increase in the incidence of complications in the younger patients (p = .02). In contrast, pharyngeal location of the FB (p = .0004), the FB's being a fish bone (p = .006), and radiolucency (p = .02) were all associated with an increased incidence of complications in patients over 10 years of age. A significant risk for complications is present for patients admitted for the management of FBs in the UADT. Older patients with sharp FBs are at greatest risk. In this group of patients, close observation in the perioperative period is required, especially if there is evidence of mucosal injury.

Low-velocity gunshot wounds to the paranasal sinuses

There are more than 200 million private firearms in the United States today. Firearm-associated deaths are the second leading cause of mortality for men 1 to 38 years of age. There are many studies in the literature concerning the management of high-velocity gunshot injuries to the head and neck. However, there are no studies in the English language literature concerning the management of isolated low-velocity gunshot wounds to the paranasal sinuses. We retrospectively reviewed 35 patients treated for low-velocity gunshot wounds of the paranasal sinuses between 1985 and 1994 at Kings County Hospital Center. The injuries sustained by these patients were less severe than previously reported for high-velocity missile or shotgun injuries. The management of these injuries is outlined with emphasis on (1) indications for angiographic studies, (2) airway management, and (3) indications for operative removal of bullet fragments.

Laryngeal tuberculosis in HIV-infected patients: a difficult diagnosis

Unrecognized laryngeal tuberculosis (TB) poses a significant hazard to otolaryngologists. However, the changing manifestations of TB in patients with human immunodeficiency virus (HIV) infection can make its diagnosis difficult. In our population of 146 patients with TB involving the head and neck, HIV infection was present in 70 cases (48%). The prevalence of laryngeal TB in this population was 5.5% (8 patients). Concomitant HIV infection was present in 2 (25%) of 8 patients with laryngeal TB. A delay in the diagnosis of laryngeal TB occurred in 100% of patients with HIV infection, compared with 17% of non-HIV-infected patients (P = .055). The cause of the delayed diagnosis was multifactorial, mainly the presence of multiple confounding variables and the carcinoma-like appearance of the laryngeal TB lesions in HIV-infected patients. To reduce risk for transmission of TB to health care providers, a high level of suspicion must be present for all patients with laryngeal lesions, especially those with HIV infection.

Regional spread of auricular and periauricular cutaneous malignancies

Over 90% of all cutaneous malignancies occur in the head and neck. Malignancies involving the external auditory meatus, auricle, and periauricular region are notoriously difficult to control. The morbidity and mortality associated with extension of these malignancies underscore the importance of complete initial removal. We present 14 patients who underwent excision of periauricular lesions. All lesions were less than 2 cm in diameter and previously excised with negative margins. These patients were subsequently referred for regional disease. Twenty-nine percent of the patients failed definitive surgical therapy. We examine the indications for regional lymphadenectomy in the treatment of auricular and periauricular cutaneous malignancies.
