The SOOF lift as an adjunct in rehabilitation of facial paralysis: help or hype?
Rehabilitation of the midface in chronic facial paralysis is one of the last frontiers in global facial reanimation. The suborbicularis oculi fat pad lift, or SOOF lift, also known as the midface lift, has been popularized in aesthetic surgery literature as a way to restore midface fullness with a youthful appearance while eliminating midface sag associated with aging. These techniques of midface aesthetic rejuvenation have recently been applied in cases of chronic facial paralysis. This article analyzes the role of the midface lift or SOOF lift in cases of facial reanimation and determines whether or not it is of benefit to patients affected by chronic facial paralysis.

Sensory recovery of innervated and non-innervated radial forearm free flaps: functional implications.
Findings reported in the literature on the sensation provided by intraorally applied innervated vs. non-innervated radial forearm free flaps differ. In an effort to understand these differences in sensory recovery, the authors carried out sensory evaluations in 12 patients who had undergone radial forearm free flaps. Seven patients had innervated flaps for defects of the tongue and floor of mouth; five had non-innervated flaps to various sites. Flap sensitivity to temperature, light touch, dull touch, and sharpness and two-point discrimination was assessed at the donor site and contralaterally, and at the recipient site and contralateral mirror-image oral mucosa. Patients subjectively rated post-reconstruction sensation and provided quality of life (QOOL) data. The innervated flaps demonstrated better sensory recovery than the non-innervated flaps, although the latter did restore reasonable sensation. This paper describes the results, compares the study to other similar studies, and discusses various factors in the sensory recovery of both innervated and non-innervated intraoral radial forearm free flaps. The authors conclude that, although the trend in this study is toward improved function with the innervated flaps, these flaps do not appear to offer major intraoral functional advantage over the non-innervated flaps, which attain reasonably effective sensory recovery from neural ingrowth, if the lingual nerve is intact.

Neural anatomy of the radial forearm flap.
Typically the lateral antebrachial cutaneous nerve alone is used to innervate the radial forearm free flap when a sensate flap is required. The authors desired, by means of fresh cadaveric microdissections and by means of local anesthetic injections in living subjects, to map the sensory nerve territories of this flap. Eight radial forearm flaps were elevated and the medial antebrachial cutaneous nerve (MABC), lateral antebrachial cutaneous nerve (LABC), and superficial radial sensory nerve (SRSN) were dissected with the aid of an operating microscope (2.5-10x) and traced to their dermal insertions. In the injection study, the MABC, LABC, and SRSN in eight forearms of 4 subjects were blocked sequentially with 2% lidocaine injections. The resulting sensory deficit from each injection was mapped on the skin and superimposed on the marked radial forearm flap territory. Distribution of the three dissected nerve regions and the sensory deficit after injection were determined by digital images and computer analysis. During flap dissections, mean nerve distributions of total flap area were as follows: LABC, 61.8% (range, 48.3-71.6%); MABC, 33.8% (range, 30.5-38.9%); and SRSN, 34.6% (range, 26.8-44.1%). After nerve block the mapped sensory areas were as follows: LABC, 62.3% (range, 44.5-88.5%); MABC, 19.6% (range, 8.0-35.8%); and SRSN, 19.5% (range, 9.9-26.3%). At least 40% of the total flap area was not innervated by the LABC as identified both by nerve dissection and sensory local anesthetic blockade. By including the LABC, MABC, and SRSN in the radial forearm flap, both the theoretical and the clinically determined useful sensory innervation of the radial forearm flap potentially would be increased.

Quality of life and disease-specific functional status following microvascular reconstruction for advanced (T3 and T4) oropharyngeal cancers.
In an effort to evaluate quality-of-life benefits of ablative head and neck cancer surgery and microvascular reconstruction, a longitudinal study was undertaken in which patients with T3 or T4 oropharyngeal cancers without systemic metastases at presentation were administered both general and disease-specific quality-of-life instruments preoperatively and postoperatively. In an initial prospective pilot study, 17 cancer patients were evaluated both preoperatively and postoperatively using the Medical Outcomes Short-Form Health Survey questionnaire (SF-36) and the Performance Status Scale for Head and Neck Cancer Patients. In the second part of the study, the need was recognized for a different disease-specific measure, for more frequent intervals of longitudinal follow-up (rather than be limited by a single data collection point), and for a noncancer control group. Since then, 17 more cancer patients were evaluated in the second part of the study and were compared with patients who had similar reconstructions after suffering head and neck trauma and also with age-matched controls. Instead of the performance status scale, the University of Washington Head and Neck Quality of Life questionnaire was substituted. Interval assessments were done at 1, 3, 6, and 12 months and preoperatively. Whereas many of the general and disease-specific quality of life subclasses initially worsened following extensive surgery and radiation therapy, most returned to the preoperative baseline by 6 months following conclusion of treatment and surpassed pretreatment values at 1 year. It can be concluded, based on this study, that large resections and reconstructions for head and neck cancer patients are justified in terms of outcome; the resection controls the local disease, and the microvascular reconstruction restores quality of life and functional status.

Free composite myo-osseous flap with serratus anterior and rib: indications in head and neck reconstruction.
BACKGROUND: Although the microvascular transfer of the serratus/rib myo-osseous composite flap has been previously described, the indications for its use in head and neck reconstruction have not been fully explored. Slender and easily contoured, rib bone offers reconstructive advantages over other bone sources under certain circumstances. The serratus/rib myo-osseous flap can provide vascularized muscle, bone, and cartilage; in combination with the latissimus dorsi muscle, the serratus/rib flap provides additional soft-tissue bulk on a single thoracodorsal vascular pedicle unrestricted by orientation requirements of the bone. Many orientations of bone and soft tissue are possible. METHODS: We describe, through three illustrative cases, the indications for this flap, which might include bony, cartilaginous, and soft-tissue requirements in the retromolar trigone region, large calvarial defects, and large composite full-thickness cheek and mandibular defects. CONCLUSIONS: The serratus/rib composite myo-osseous flap reliably provides vascularized bone of relatively delicate composition which offers advantages in certain reconstructive circumstances. In addition, when combined with latissimus dorsi muscle on a single vascular pedicle, it supplies additional soft-tissue bulk which can be positioned without being constrained by the bone placement. Finally, this is a useful "backup" supply of vascularized bone when other sources cannot be used due to, for example, inability to use fibula in the face of severe peripheral vascular disease and inability to use iliac crest if this has been previously used as a donor site for nonvascularized free grafts (as in secondary reconstructions).

Baseline and post-treatment assessment of the general health status of head and neck cancer patients compared with United States population norms.
BACKGROUND: It is a common perception that the overall health of patients with head and neck cancer (HNC) is likely to be poor compared with the general population. This project was undertaken to investigate the pre- and post-treatment, global health status of HNC patients in comparison with age-matched, U.S. population norms using a self-administered general health status survey. METHODS: Between July 1, 1993, and May 1, 1996, 180 patients underwent pretreatment and 6 month follow-up evaluation with the standard version of the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36). The SF-36 scale scores, means, standard deviations, and 95% confidence intervals were calculated for each SF-36 scale as well as for physical-health-component summary scores (PCS) and mental-health-component summary scores (MCS). Comparisons of these scores were made to U.S. population normative data. Pretreatment and 6-month follow-up SF-36 scores were compared. RESULTS: In the 45-54-year age group, all 8 SF-36 scale scores, the PCS, and MCS scores were significantly worse for the HNC patients in comparison with age-matched norms (p < .05). In the 55-64-year age group, the HNC patients were worse in 5 of the 8 SF-36 scale scores and the MCS score in comparison with age-matched norms (p < .05). In the 65-74-year age group, the HNC patients scored significantly worse in the mental health scale. In the comparison of pretreatment and 6-month follow-up scores, the HNC patients had significant decreases in the physical functioning scale (p = .003) and the PCS score (p = .047). The HNC patients showed significant improvement in the mental health scale (p = .049) and improvement in the bodily-pain scale, which approached significance (p = .053) at 6-month follow-up. The HNC patients showed a marked decrease in general health status with increasing stage of HNC. CONCLUSIONS: This work provides objective support for the perception that many HNC patients are initially seen for treatment with baseline health status functioning significantly below their age-matched contemporaries in the general population. An educated evaluation of global health outcomes following treatment in the HNC patient population must begin with an accurate pretreatment assessment of these parameters. Self-reported health-status assessment (HSA) is a useful means of evaluating global health status in this patient population.

Orbital involvement in allergic fungal sinusitis.
BACKGROUND: Although allergic fungal sinusitis is a relatively common, noninvasive form of paranasal sinus mycosis, and despite frequent orbital involvement, there have been few reports of this condition in the ophthalmic literature. METHODS: Two cases of allergic fungal sinusitis having orbital symptoms are described. The current classification, typical presentation, and ideal management of fungal sinusitis are reviewed. RESULTS: Distinguishing radiologic and pathologic features were present in both patients. Aspergillus flavus was cultured in one case, and Bipolaris spicifera was cultured in the other. CONCLUSIONS: Allergic fungal sinusitis is a unique subset of sino-orbital disease with highly characteristic clinical, radiologic, and pathologic features. Unlike invasive forms of mycotic disease, allergic fungal sinusitis may be managed adequately with surgical debridement, aeration of the involved sinuses, and systemic and topical corticosteroids.

Combined transconjunctival/intranasal endoscopic approach to the optic canal in traumatic optic neuropathy.
Surgical decompression of the optic canal is indicated in patients with traumatic optic neuropathy who fail to respond to corticosteroids. Traditional surgical approaches to the orbital apex have been effective in achieving optic nerve decompression but require either a craniotomy, provide limited exposure with late identification and protection of the optic nerve, or require external incisions. The combined transconjunctival/intranasal endoscopic approach to the optic canal offers sufficient exposure, allows early identification and protection of the optic nerve, provides space for the use of multiple surgical instruments, obviates a craniotomy and external incisions, and can be performed quickly with minimal morbidity. The technique of combined transconjunctival/intranasal endoscopic optic nerve decompression will be described and the experience with nine cases will be presented.

Intracranial complications of sinusitis.
Intracranial suppurative complications of sinusitis remain a challenging and contemporary topic. To determine the prevalence of sinogenic sources in intracranial infectious complications, we reviewed the records at a large public hospital between 1985 and 1995. There were 203 patients with 212 suppurative intracranial infections. Sinogenic sources were identified in 12 patients with 19 infections. Most patients had ethmoid or frontal sinusitis. We discuss the presentation, microbiology, diagnosis, treatment, and clinical course of these 12 cases. The diagnosis of intracranial complications of sinusitis requires a high index of suspicion and radiographic imaging of the head and paranasal sinuses. The mean hospital stay was 31.4 days and all 12 patients survived, although three patients had significant neurologic sequelae.

An algorithm for management of residual posttraumatic calvarial defects in adults.
For the discussion of options in late reconstruction of residual posttraumatic calvarial defects in adults, the calvaria is divided into three reconstructive zones. Zone 1 comprises the frontal sinus region and the contour of the supraorbital brow; Zone 2 comprises the smooth, cosmetically visible prehairline forehead; Zone 3 comprises the posthairline area and the calvaria. The particular reconstructive requirements (autogenous bone versus alloplastic material) of each zone are described and illustrated with clinical cases. The merits of bone from various donor sites and those of alloplastic material are discussed. The authors present an algorithm of reconstructive choices for residual posttraumatic calvarial defects in adults based on the nature of the defect and the aesthetic reconstructive zone.

Superficial versus deep: options in venous drainage of the radial forearm free flap.
We performed a fresh cadaver dissection study of the superficial venous system (cephalic vein and its branches) and the deep venous system (venae comitantes) of the radial forearm to assess the suitability of each system for venous anastomosis during free tissue transfer. We used methyl methacrylate to evaluate vessel diameters and anatomic variability of both venous systems. Colored radiopaque injectate allowed us to combine anatomic dissection with tissue radiographs. We discovered the cephalic vein to invariably be of larger caliber than the venae comitantes. Ensuring capture of the cephalic vein in the flap necessitated additional dorsoradial subcutaneous dissection beyond the boundaries of the skin flap in four of ten specimens. The vessel diameters of the venae comitantes in four cadavers were less than 2 mm. Proximal confluence of the two venae comitantes, and communication between the deep and superficial venous systems were encountered in only four cases. In these cases, had an anastomotic site been chosen proximal to such a communication to ensure greater vessel caliber, pedicle length probably would have made free tissue transfer unwieldy. We recommend mapping the course of the cephalic vein before flap elevation and maintaining a wide proximal subcutaneous pedicle to capture the best possible superficial drainage system. If the superficial venous system has been damaged (as by previous intravenous catheterization), one may not necessarily be able to rely on the vessel caliber of the deep venae comitantes for microvenous anastomosis.

Endoscopic management of a giant cholesterol cyst of the petrous apex.
Giant cholesterol cyst (GCC) of the petrous apex is a rare clinical entity. This benign cystic lesion can cause neurologic deficits and vascular compromise by persistent growth and progressive bone destruction. Magnetic resonance imaging studies of GCC show the lesions to be hyperintense on T(1)-weighted sequences with progressively lower signal intensities on the first and second echoes of T(2)-weighted sequences. These findings are relatively specific for GCC, permitting a narrow differential diagnosis. The goal of surgery is to provide adequate drainage with the creation of a permanent fistula. The classic approaches to these lesions are the posterior fossa craniotomy and the middle fossa extradural craniotomy. The translabyrinthine approach provides wide exposure at the expense of cochlear and vestibular function. The transsphenoidal approach provides adequate drainage with hearing preservation and no craniotomy. The endoscopic, endonasal transsphenoidal approach to a 2.5 cm GCC of the petrous apex accomplished complete drainage with the creation of a fistula. Advances in endoscopic technique and instrumentation facilitated the addition of the approach to the surgeon's armamentarium. In selected cases, this approach provides adequate surgical exposure with minimal morbidity.

Life-threatening presentations of fibrovascular esophageal and hypopharyngeal polyps.
Giant fibrovascular polyps of the esophagus and hypopharynx are benign tumors of the upper digestive tract. Although a rare cause of asphyxiation, laryngeal impaction by a regurgitated polyp of the esophagus may be the initial symptom that brings the patient to request medical attention. Two new cases of giant fibrovascular polyps with dramatic and potentially life-threatening presentations illustrate the unpredictable behavior of these unusual tumors. Both patients presented to the emergency center with a history of coughing and eructation followed by temporary airway obstruction that was relieved by clenching a regurgitated fleshy mass between the teeth. Diagnostic and therapeutic intervention requires aggressive airway management, radiographic and endoscopic evaluation, and definitive surgical treatment. Tracheotomy was required in one patient, and successful endotracheal intubation provided satisfactory airway control in the second. Esophagoscopy revealed the origin of both tumors to be near the cricopharyngeal muscle. Complete surgical excision was curative in both cases.

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.

Efficient adenoviral-mediated ornithine transcarbamylase expression in deficient mouse and human hepatocytes.
100% of primary human hepatocytes infected with an adenoviral vector carrying beta-galactosidase expressed the exogenous gene. Expression was also achieved in > 40% of adult mouse hepatocytes in vivo. Normal levels of activity were achieved in mouse ornithine transcarbamylase (OTC)-deficient primary hepatocytes using another adenoviral vector carrying human OTC cDNA. Study of OTC-deficient primary human hepatocytes from a single patient confirmed the utility of adenoviral delivery of OTC. We describe adenoviral-mediated exogenous gene expression in human and mouse hepatocytes in vitro and in mouse liver in vivo. Data suggest that adenoviral vectors may be useful for correcting OTC deficiency.

In situ skin grafting of free muscle flaps prior to microvascular transfer to provide intraoral lining for full-thickness defects.
BACKGROUND: Previously, the importance of providing skin for intraoral lining for full-thickness mucocutaneous defects has been emphasized. More recently, simple skin grafting of the intraoral portion of muscle flaps has been described. METHODS: Six patients were evaluated who had full-thickness mucocutaneous defects reconstructed by means of free muscle flaps with skin grafting of the intraoral muscle surface. An illustrative case is provided. A technique of preplacing the skin graft on the muscle prior to microvascular transfer is described. Mucosal biopsies were performed at the reconstruction site. RESULTS: All patients had complete take of the skin grafts. No fistulas occurred. Functional and esthetic results were satisfactory. CONCLUSIONS: The ideal candidate for this form of reconstruction is one in whom there is a large, full-thickness mucocutaneous defect. Preplacement of the skin graft reduces ischemia time, allows suturing of the skin graft to the muscle surface outside the narrow confines of the oral cavity, and enables placement of multiple quilting sutures that secure the graft against shear forces and so obviate the need for a stent dressing.
