Tumefactive cartilage proliferation after rhinoplasty. A newly reported complication.

OBJECTIVE: To describe and document the development of tumoral proliferation of cartilage in 4 patients after nasal surgery, a complication that, to our knowledge, has not been reported before. DESIGN: Similar postoperative nasal masses were excised from 4 patients who underwent rhinoplasty. Histopathologic evaluation was carried out to identify the nature of the lesions and to provide a basis for rational management of similar lesions subsequently encountered. SETTING: Academic tertiary referral center. PARTICIPANTS: Four healthy patients (3 women and 1 man) ranging in age from 21 to 49 years. Two of the patients underwent routine rhinoplasty with resection of cephalic margins of alar cartilages, and 2 underwent augmentation procedures with implantation of auricular cartilage. INTERVENTION: Discrete firm masses were excised from each patient's nose approximately 1 year after the most recent rhinoplastic procedure was performed. Histological evaluation was carried out on each specimen. RESULTS: All 4 masses were found to consist of tumefactive proliferation of cartilage. Clonal proliferation and mild nuclear atypia were observed. CONCLUSIONS: After rhinoplasty, progressive asymmetrical fullness in or adjacent to cartilaginous structures or graft material should suggest the possibility of tumefactive proliferation of cartilage and should be evaluated with surgical exploration. All areas of thickened cartilage should be excised completely, with immediate auricular cartilage reconstruction of resulting anatomical defects. Perichondrium should be completely removed from auricular cartilage implants in the nose, and mechanical injury to the graft should be minimized. We strongly caution against morsellizing dorsal cartilage implants for nasal reconstruction.

Isolated Castleman disease of the neck: MR findings.

Castleman disease in an 11-year-old girl appeared as a neck mass that grew despite antibiotic treatment. MR showed a well-defined solid mass, isointense with muscle on short-repetition-time/short-echo-time images, with a stellate area of central hypointensity on long-repetition-time/long-echo-time images, that did not enhance with gadolinium.

Methods and materials for wound closure.

Over the years, a number of different modalities have become available to close wounds. Before selecting a method of wound closure, the characteristics of the specific tissues to be closed and the anticipated time for wound healing to occur must be considered. This article reviews the methods available for tissue closure for the head and neck surgeon.

Torn earlobe: a new approach to management with a review of 68 cases.

The torn earlobe is a common problem, yet no objective analysis of causation or management is found in the literature. We present a series of 68 patients with statistical data on earlobe characteristics and cleft-related historical factors. We describe three new methods of repair: two for full clefts and one for partial clefting (ie, elongation of the piercing site without penetration of the inferior rim). We report follow-up from 4 to 10 years, with a 91% success rate for lobe appearance and a 1.2% recurrence of clefting. We offer guidelines for repair and repiercing based on lobe thickness and shape. We make recommendations for earring use based on lobe characteristics and historical development of the defect.

Fetal wound healing.

Wound healing research has produced some startling discoveries during the past decade. Foremost among these is the observation that cutaneous wounds created and healed in utero are histologically indistinguishable from intact, unwounded tissue. Observers have documented that the acute inflammatory response and endogenous immunoglobulins that characterize healing in human beings after birth are absent in the fetal wound. Determination of the cellular and biochemical differences between fetal and postdelivery wound healing offers the promise of improved control over the process of tissue repair. Another promise of fetal wound healing research is the option of in utero repair of defects such as cleft lip and palate. We review what is known at present about fetal wound healing.

Methods and materials for wound management.

Rumor, myth, and unsubstantiated opinion have guided wound management since our forebearers achieved upright ambulation. The past decade has seen discovery of specific substances and pathways that initiate, control, and terminate healing. The roles of oxygen, nutrition, and growth factors are rapidly revealing themselves to wound healing researchers, and a scientific basis for wound management is emerging. Although the healing process still harbors much mystery, we know enough to improve our methods of wound management. We can now pick from a variety of tools for surgical incision. Scientific studies help in the choice of sutures, needles, and needle holders, as well as alternative closure methods and materials. Natural and synthetic tissue adhesives vie with staples and tapes for use in wound repair. Dressing materials may be active, passive, selectively interactive, or inert. Wound management can be changed to meet changing wound needs, with dressings as diverse as hydrocolloids, silicone gels, and amino acids. We have new ways of improving hypertrophic scarring and practical hopes for its prevention. This article offers a summary of currently available methods and materials for wound management, along with the scientific information that supports and guides their use.

Alternatives to packing in septorhinoplasty.

Nasal packing is considered routine by most physicians and patients at the completion of nasal and septal surgery. Yet the rationale for this maneuver is not clearly defined by reported investigation or logical analysis. We discuss 75 consecutive nasal surgical procedures completed without packing. There were two postoperative episodes of bleeding, both from pyriform aperture incisions for lateral osteotomy and both managed in the recovery room with an absorbable gelatin sponge. Technical refinements such as scrupulous preoperative history taking, through-and-through suturing of the entire septal flaps, small-caliber osteotomy, meticulous closure of all intranasal incisions, and proper application of a conforming dressing are essential for hemostasis. We offer specific procedural guidance to minimize the risk of postoperative nasal bleeding.

Invasive intramuscular hemangiomas of the head and neck.

Intramuscular hemangiomas make up less than 1% of all hemangiomas [1]. These invasive and aggressive lesions appear to have a predilection for large muscle masses. They can be strikingly aggressive in the head and neck, and persistence despite radical treatment is common. Spontaneous resolution in adults to our knowledge has not been reported in the literature. We present a case report of an invasive intramuscular hemangioma involving the parotid gland, the masseter and pterygoid muscles, and the infratemporal fossa after local resection of an apparently isolated lesion of the lip and the submandibular triangle. We describe a detailed course of treatment and review the literature.

Dentoalveolar considerations in the management of facial trauma.

Facial trauma may result in damage to the structures of the mouth, both by direct insult and by hindering access for routine oral health and hygiene measures. Successful management must include consideration of the stomatognathic system. The four major areas of consideration are dentoalveolar response to the forces of trauma and repair, evaluation and management of changes in vitality of the dental pulp, control of infectious and inflammatory periodontal disease throughout the period of evaluation and management, and restoration of the dentition and supporting structures. Guidelines are offered for use in the management of patients with facial trauma in each specific area presented for consideration.

Auditory distortion.

The auditory system responds to pulsatile energy flow from the environment. Compression and rarefaction of gaseous molecular mass is transduced into electromechanical forms, in order to produce an effect at the cortical level. For energy input to have consistent meaning, transduction must preserve information coded within the pattern of energy flow. Distortion, or alteration of the original form, occurs in many ways throughout the chain of generation/transmission/reception/interpretation. Parameters of energy flow are discussed, and distortion of each parameter is presented in a context which permits the development of a distortion-based analysis of common clinical problems in otolaryngology.

Third branchial cleft sinus: an unusual cause of neck abscess.

Sinuses and fistulae of the third branchial cleft or pouch are rarely encountered. We have cared for a child with a history of multiple neck masses and abscesses, in whom the causative factor seems to have been an unrecognized branchial cleft sinus. This case suggests the need for contrast radiography of the hypopharynx in children with recurrent neck abscess, and dramatizes the need to exercise all reasonable diagnostic options before proceeding with surgery of newly presenting neck masses in children.

Middle ear immittance in rheumatoid arthritis.

Audiologic and electroacoustic immittance measurements were obtained from each ear of 23 patients with rheumatoid arthritis and 13 normal control subjects. Audiologic findings revealed 14 patients with rheumatoid arthritis with hearing loss of either conductive (three patients) or sensorineural (11 patients) type, while only two control subjects demonstrated hearing loss, both of sensorineural type. Immittance data revealed abnormal findings in 59% of the patients with rheumatoid arthritis as compared to only 4% of the control subjects. The increased incidence of sensorineural hearing loss in the sample with rheumatoid arthritis could not be readily explained. The observed prevalence of abnormal immittance findings in patients with rheumatoid arthritis suggested either increased middle ear stiffness or increased stiffness associated with decreased stability of ligamentous anchorage.
