Pathogenesis of peritonsillar abscess.

The pathogenesis of peritonsillar abscess is described in textbooks as being a direct communication and progression of acute exudative tonsillitis. Little study has been done on the true etiology and pathogenesis of peritonsillar abscess. This paper focuses on the pathogenesis of peritonsillar abscess. A group of salivary glands (Weber's glands) proven to be located in the supratonsillar space have been shown to be implicated in the pathogenesis of peritonsillar abscess. A review of peritonsillar abscess has been undertaken, and evidence has been presented to support the premise that the true cause for peritonsillar abscess is not necessarily an extension of an acute exudative tonsillitis, but an abscess formation of Weber's salivary glands in the supratonsillar fossa.

Rhinorrhea with airway obstruction.

Life endangering airway obstructions have many facets and causes. Rhinorrhea is a symptom whose etiology may be overlooked if an immediate crisis of airway obstruction is present. Unless the cause for the obstruction or rhinorrhea is investigated it may go undetected and continue to present further problems for the patient. This is especially true of infants under six months of age who are obligate nasal breathers. The following are three cases representing this problem.

Maxillary sinus development in patients with cleft palates as compared to those with normal palates.

Maxillary sinusitis appears to be more prevalent in the cleft palate population than in the normal population. The increase in sinusitis may be due to the fact that the maxillary sinus develops differently embryonically in cleft palate patients than in those patients with normal palates. A double blind study was done by measuring the maxillary sinus cephalometric x-rays in cleft palate patients and then comparing them to patients with normally developed palates. The groups studied were 3 months to 20 years of age. It was concluded that in each of these groups there was no significant difference in size, shape, or rate of development of the maxillary sinus in cleft palate patients compared to the normal population. It is probable that the increased incidence of maxillary sinusitis in cleft palate patients is due mainly to the open palate with constant contamination of the nasal mucosa by food pushed into the nares and sinus ostia, resulting in maxillary sinusitis.

Passy-Muir tracheostomy speaking valve on ventilator-dependent patients.

Communication for handicapped ventilator-dependent patients is a problem, not only for the patient but also for the healthcare personnel. The inability of these patients to vocalize is a paramount problem in their care. This study evaluates the efficacy of a one-way speaking valve on ventilator-dependent patients and evaluates the resulting effectiveness of their speech. Fifteen ventilator-dependent patients were fitted with the one-way Passy-Muir Tracheostomy Speaking Valve and their communicative skills and ease of vocalization were evaluated. This clinical evaluation was done by the patient, a speech pathologist, two nurses in charge of the patient, and the patient's private physician. No complications were observed in any of the patients. All 15 patients showed marked improvement, not only in speech intelligibility but in speech flow, the elimination of speech hesitancy, and speech time. This ability to communicate enhanced the care given by the healthcare personnel. In conclusion, use of the Passy-Muir Tracheostomy Speaking Valve restored verbal communicative skills of ventilator-dependent patients, facilitated care, and greatly enhanced the mental outlook of these patients without observed complications.

Bilateral vocal cord teflon injection. An ineffective treatment for recurrent aspiration pneumonia.

Recurrent aspiration pneumonia is a potentially lethal problem, and its treatment is controversial. A variety of procedures have been advocated to prevent aspiration. These are reviewed briefly. We have been dissatisfied with established procedures because they usually require external approaches with considerable complexity and potential complications. Therefore, we attempted to obstruct the glottic airway by injecting both vocal cords with Teflon in a series of patients with recurrent aspiration pneumonia secondary to severe neurologic impairments. Since Teflon injection of the vocal cords bilaterally did not reliably prevent aspiration, we cannot recommend it for routine use in the treatment of chronic aspiration.

Photoradiation therapy of head and neck cancer.

We have embarked upon a pilot study of photoradiation therapy (PRT) in the treatment of persistent or recurrent cancer of the head and neck, utilizing the photosensitizing agent, hematoporphyrin derivative (HPD). This treatment is based upon selective concentration of HPD within malignant tissue, with resultant necrosis upon illumination with light of the appropriate wavelength (640 nm). Patients entered in this trial have failed all forms of conventional therapy. Twenty-one patients with local recurrence were treated. Sites of recurrence were: tongue (9); nasopharynx (3); floor of mouth (2); soft palate (2); oropharynx (1); buccal mucosa (1); maxilla (1); larynx (1); and basal cell nevus (1). There were six complete responses and twelve partial responses (greater than 50% reduction). These responses are clinically significant, with some complete responses lasting over 1 year after a single course of therapy. Ten patients with cutaneous metastases from head and neck primary tumors were also treated. There were two complete responses and three partial responses. However, these patients rapidly developed new tumors in areas adjacent to those previously treated. Less than complete responses could be augmented by repeated applications of this technique. The success of this pilot study combined with the accessibility of head and neck primaries suggest that there should be a clinical trial of HPD-PRT in early mucosal cancer of the head and neck region.

Metastatic small cell carcinoma to the masseter muscle originating from the uterine cervix.

Metastatic tumors to the head from infraclavicular primaries are relatively uncommon. The vast majority of primary tumors that metastasize to the head originate from the lung and breast. Tumors metastatic to the masseter are exceedingly rare with only one other case being reported in the literature. The case of a 34-year-old woman with a history of surgically-treated small cell carcinoma of the uterine cervix is presented. This case and our review of the literature illustrates the unusual nature of metastatic patterns in the head and their diagnostic complexity. Masses localized to the buccomasseteric region are usually considered to be of parotid origin. The differential diagnosis for masses in this area is generally limited to cogenital, inflammatory, or neoplastic lesions. Though uncommon, metastatic tumors from non-head and neck primary malignancies should be considered in the diagnosis as they may herald the onset of a new disease or the recurrence of cancer.

Unusual foreign bodies of the temporal bone.

Foreign bodies that result from traumatic injury may be the cause of many clinical symptoms. Chronic otitis externa is one of the many clinical symptoms following a traumatic perforation of a foreign body from the oral cavity penetrating the deep tissue of the neck and ultimately lodging in the external ear canal. We discuss two such uncommon cases.

Bronchopulmonary levage to remove pulmonary casts and plugs.

Therapy for such obstructive pulmonary lung diseases as alveolar proteinosis, pneumonia, asthma, bronchiectasis, and cystic fibrosis, ranges from medical therapy to inhalation therapy to direct bronchoscopy and irrigation. The basic pathophysiologic feature is the retention of mucous secretions and foreign material within the lungs and therapy directed to removal of these secretions. Bronchopulmonary lavage recently has been suggested as an effective tool toward resolution of these illnesses. The otolaryngologist, who is adept in endoscopy, is asked to perform bronchoscopic procedures with washings to aid in the alleviation of these obstructive pulmonary diseases. This paper deals with the effectiveness of massive bronchopulmonary lavage in the elimination of severe chronic obstructive pulmonary lung diseases.

Endotracheal intubation. Complications in neonates.

Different opinions have developed on the use of endotracheal intubation in newborns and neonates for airway distress syndrome. The ensuing complications of the prolonged use of these airway tubes are drawing increased interest. This article reviews the case reports of 88 patients who received endotracheal intubation for airway problems and evaluates the complication rate as it correlates to the various contributing factors of duration of intubation, size of endotracheal tube, frequency of intubation, concomitant infections, and age of patient, which all lead to the complication rate.
