Recurrent adult myofibromatosis. A case report.

Myofibromatosis generally is regarded as a fibrous proliferative disease of neonates and children that, even when multicentric, has an excellent prognosis and a propensity for spontaneous involution. Reported is a case of solitary, locally recurrent myofibromatosis in the ear canal of an adult patient. It was initially thought to be a leiomyoma. The diagnosis of myofibromatosis was made on the basis of its histologic appearance and corroborated by immunohistochemical stains. Clinicians and pathologists should be aware that myofibromatosis may occur in adults in unusual locations, with a potential for local recurrence. Furthermore, its histologic appearance may mimic that of other mesenchymal neoplasms.

Polyethylene oxide gel: a new dressing after endoscopic sinus surgery.

The purpose of dressings after endoscopic sinus surgery is to absorb secretions, tamponade bleeding, discourage adhesions, and facilitate sinus and nasal hygiene. The ideal dressing should conform to the irregularities of the nasal-sinus cavity and resist adherence to the wounds so it can be easily removed. It should be economical, non-irritating, and antiseptic. The failure of previous dressings to fulfill all of these criteria led the author to evaluate a new alternative. Polyethylene oxide gel (Vigilon) was identified as a potential improvement and investigated in a clinical trial of 60 cases. This paper presents the author's observations and technique for application. Polyethylene oxide gel resulted in no significant complications. It appears superior to previously described dressings, primarily because of patient comfort at removal.

Polyethylene oxide gel. A new intranasal dressing after septorhinoplasty.

The purpose of intranasal dressings after septorhinoplasty is to absorb secretions, stop bleeding, act as an internal splint, discourage adhesions, and facilitate nasal hygiene. The ideal dressing should conform to the irregularities of the nasal cavity and resist adherence to the wounds of the nasal lining so it can be easily removed. It should be nonirritating, antiseptic, and economical. The failure of previously reported dressings in one or more of these requirements led us to evaluate a new alternative. Polyethylene oxide gel (Vigilon) was identified as a potential improvement and investigated in 48 patients over 17 months. There were no significant complications. Polyethylene oxide gel appears superior to previously described dressings, primarily because of comfort for the patient at removal.

Oral dantrolene sodium for tonsillectomy pain: a double-blind study.

Tonsillectomy in adults and older children is typically accompanied by 7 to 14 days of pain. On the basis of clinical observations of patients treated perioperatively with dantrolene sodium for malignant hyperthermia, we hypothesized that pharyngeal muscle spasms are a major factor in tonsillectomy pain. We entered 113 patients, 11 years of age and older, into a double-blind, placebo-controlled study to evaluate the effectiveness of dantrolene sodium in reduction of tonsillectomy pain. Patients were randomly assigned either dantrolene (1.5 mg/kg per day) or placebo orally four times a day for 5 days postoperatively. On a standardized questionnaire, the patient recorded pain, diet, activity level, analgesics, and side effects, daily for 2 weeks. Also, alkaline phosphatase (alk phos) and serum aspartate aminotransferase (SGOT) levels were determined before the operation and 2 weeks after. Patients who received dantrolene had no significant differences in subjective pain, diet, or activity level scores from those of patients who received placebo. Dantrolene patients did, however, require significantly less analgesic use than placebo patients (p = 0.034, 0.015, and 0.005 for postoperative days 2, 3, and 4, respectively). There was no significant difference in side effects or changes in liver enzyme between the dantrolene and placebo groups. We conclude that dantrolene sodium, given in the dosage noted, is effective in reduction of analgesic requirements after tonsillectomy.

Life-threatening soft-tissue infections of the neck.

Four adult patients had life-threatening soft-tissue infections of the neck. One had Hemophilus influenzae infection, one had Streptococcus pyogenes infection, and two had polymicrobial mixed aerobic and anaerobic infections. Three of the four patients died despite appropriate antimicrobial therapy and surgical intervention. These cases demonstrate the spectrum of serious soft-tissue infections of the neck in both the compromised and the uncompromised host. Soft-tissue infections of the neck may be necrotizing or nonnecrotizing. Cellulitis secondary to H. influenzae and beta-hemolytic streptococci is usually non-necrotizing, whereas necrotizing infections are caused most commonly by synergistic organisms. Potential complications include septic shock, disseminated intravascular coagulation, acute renal failure, adult respiratory distress syndrome, mediastinitis, and pericarditis. Early recognition with aggressive medical and surgical therapy is essential to reduce the mortality.

Respiratory distress after recurrent laryngeal nerve sectioning for adductor spastic dysphonia.

Adductor spastic dysphonia is a voice sign associated with various neurologic and psychologic disorders. Treatment of spastic dysphonia in selected patients is unilateral recurrent laryngeal nerve sectioning. Except for voice change or, in some patients, return of phonatory spasticity, there have been no long-term sequelae or complications of this treatment. We describe three patients with adductor spastic dysphonia who underwent recurrent laryngeal nerve sectioning and who, 3 to 38 months later, suffered respiratory distress that required tracheostomy. The respiratory distress in all three patients was due to episodic jerky vocal cord hyperadductions that caused stridor during inspiration and expiration. These repetitive laryngospasms during respiration and phonation were progressive. Two patients needed an arytenoidectomy to achieve a useful voice, and all three required a permanent tracheostomy to alleviate inspiratory laryngeal obstruction.

Gross and microscopical blood supply of the trachea.

Twenty-one human tracheal specimens were perfused and dissected, 10 with conventional techniques and 11 with clearing and microdissection techniques. The lateral pedicles of the trachea and esophagus induct vessels from the inferior thyroid, subclavian, supreme intercostal, internal thoracic, innominate, and superior and middle bronchial arteries. These vessels are interconnected along the lateral surface of the trachea by an important longitudinal vascular anstomosis. From the 2 lateral longitudinal anastomoses the lateral and anterior tracheal walls receive their blood supply through transverse segmental vessels that run in the soft tissues between the cartilages. These transverse vessels interconnect the longitudinal anastomoses across the midline and feed the submucosal capillary network that arborizes richly beneath the endotracheal mucosa. The tracheal cartilages receive nourishment from the capillary bed applied to their internal surface. The esophageal arteries and their subdivisions that supply the posterior membranous wall of the trachea contribute almost nothing to the circulation of the cartilaginous walls.

"Colonic type" adenocarcinoma of the nasal cavity and paranasal sinuses.

Primary "colonic type" tumors of the nasal cavity and paranasal sinuses are adenocarcinomas with histologic features similar to those of colonic cancers. Their behavior is one of local invasion and recurrence. Unlike tumors of the colon, they rarely metastasize. Surgical resection by means of lateral rhinotomy with or without radiation is the treatment of choice. Prognosis is poor. This type of tumor should be recognized by pathologists and its implications should be known to head and neck surgeons.

Malignant pyoderma.

Malignant pyoderma is a rare inflammatory pyoderma of unknown cause with characteristic destructive and necrotizing ulcers limited to the face, neck, and upper trunk. The typical lesions are small, purulent, periauricular ulcers. Enlargement and coalescence result in extensive lesions that may ultimately destroy portions of the external ear. The histopathologic findings are acute and chronic inflammation with necrosis. Treatment consists of long-term systemic corticosteroids. We present two new cases and alert otolaryngologists to the seriousness of this disease.
