A visor flap may be used for anterior lesions in the oral cavity if one wishes to avoid external facial incisions heart attack recovery diet discount moduretic 50mg with visa, but this is done at the expense of bilateral mental nerve sacrifice blood pressure phobia buy 50mg moduretic mastercard. Carcinomas arising at or extending to the posterior portion of the oral cavity may require a mandibulotomy for adequate exposure. Placing the mandibulotomy anterior to the mental foramen preserves the integrity of the inferior alveolar nerve and may exclude the osteotomy from portals typically employed for adjuvant external beam radiation. Oncologically, there is no benefit from removal of a portion of the mandible simply to keep the contents of a neck dissection in continuity with the primary resection. Functionally, resection of the anterior arch of the mandible results in significant disability, including drooling and interference with eating, in direct relation to the amount of bone removed. Aesthetically, this may also result in a significant recession of the pogonion, leading to what is known as an "Andy Gump" deformity. Marginal mandibulectomy is acceptable for lower gingival cancers if the erosive defect does not extend to the inferior alveolar canal and at least 1 cm of bone inferiorly can be preserved. The use of internal fixation and microvascular free tissue transfer reconstruction can reduce the risk of secondary fracture when marginal mandibulectomy is employed. However, the rehabilitation of hard palate defects with the use of prosthodontics, in addition to free tissue transfer, is significantly easier than that of mandibular defects. An important concept in the management of cancers of the oral cavity concerns the adequacy of surgical margins. Edentulous patients are generally not good candidates for marginal mandibulectomy. It should be remembered, however, that oral cavity margins shrink approximately 30 to 50% from the in situ measurement by the surgeon to the final pathologic evaluation after formalin fixation. Modalities for primary radiation include wide-field or intensity-modulated external beam radiation therapy, brachytherapy, or a combination of modalities. Definitive radiotherapy shares comparable results with surgical treatment for early-stage oral cancers and is therefore preferred for early-stage lesions in patients in whom surgical management is contraindicated. The dosage of radiation depends upon the extent of disease and the tolerance of surrounding normal tissues to radiation injury. Intensity-modulated radiation therapy may increase the amount of radiation delivered to the tumor itself while sparing the surrounding normal tissues, such as the major salivary glands and the mandible, leading to a potential decrease in xerostomia and osteoradionecrosis, respectively. The risk of osteoradionecrosis necessitates comprehensive dental care prior to the initiation of radiotherapy. The adjuvant use of hyperbaric oxygen, either prophylactically or for treatment of mandibular osteoradionecrosis, although commonly practiced, remains controversial. The price paid for this improved survival is an increase in mucositis and hematopoetic toxicity. Combined Therapy A combination of surgery and radiation or chemoradiation is recommended for advanced cancers of the oral cavity in light of the high propensity for locoregional failure. The current standard of care for combined modalities is surgery followed by adjuvant radiotherapy with or without chemotherapy. Adjuvant therapies have been shown to improve locoregional control, but it should not be construed as a panacea for inadequate surgery. For example, adjuvant radiation therapy does not decrease the risk of local recurrence in patients with positive margins to a level comparable to patients with negative margins treated without radiation. Adjuvant radiation with chemotherapy is indicated for patients with positive margins and Table 110-3 Indications for Postoperative Radiation therapy versus Indications for Chemoradiotherapy Indications for Postoperative Radiation Therapy Advanced tumor classification (T3-4) Advanced nodal classification (N2-3) Perineural invasion Lymphovascular invasion Indications for Postoperative Chemoradiotherapy Positive margins Lymph node extracapsular extension nodal metastases with extracapsular extension (Table 110-3). The addition of chemotherapy to radiation has been shown to improve locoregional control and survival in properly selected patients. Prognostic models have been developed and validated to improve risk stratification for individual patients after surgery and to help assist in the decision-making process regarding the application of adjuvant therapies. The ideal timing of postoperative radiotherapy with or without chemotherapy is six weeks following surgery. Nomograms can provide an individualized risk assessment that can be helpful in deciding adjuvant treatment after surgery. A prospective randomized trial demonstrated effective treatment of oral leukoplakia with a six-month trial of isotretinoin (13-cis-retinoic acid) with significant reduction in lesion size and reversal of dysplasia.

Treatment via an endoscopic approach is often completed via an outpatient surgery or a short hospital stay following surgery hypertension uncontrolled icd 9 code order cheap moduretic on line. Radiation therapy blood pressure medication first line cheap moduretic 50mg mastercard, on the other hand, requires a six to seven week course of treatments five days a week. Occasionally, this difference alone prompts some patients to choose one treatment over the other. It is also important to note that multiple studies have shown that radiation therapy for T1 glottic carcinoma is significantly more costly than an endoscopic resection. This has even been shown to be true after adjusting for cost variations in different countries. There have been multiple studies examining local control rates and cure rates of both surgery and radiation therapy for T1 glottic cancers. In general, the studies do not demonstrate any clear difference between these modalities in disease control. Gourin et al studied 89 patients with T1 carcinoma at all laryngeal sites and compared survival for those who received radiation therapy versus those who received surgery in a retrospective fashion; with regard to overall survival, no difference was found when outcomes were examined by treatment modality. Furthermore, many centers do not have the necessary surgical expertise available to complete these procedures. In these patients, radiation therapy is an excellent choice that has demonstrated essentially equivalent rates of cure. Disease involving the anterior commissure is a special consideration, as discussed above. The ideal modality for disease in this area is still controversial and most likely depends on several host and tumor related factors. Total laryngectomy was first described in the late 1800s and is utilized today with little modification. Total laryngectomy involves the removal of the entire larynx including the hyoid bone and cricoid cartilage. A total laryngectomy with tracheoesophageal puncture with or without postoperative radiotherapy is anoption for T3 glottic cancer and may be the best alternative in some patients. That is, those with poor pulmonary reserve or comorbidities making them poor chemoradiation candidates may require surgery. Total laryngectomy may also be an option when there is concern that chemoradiation will lead to severe aspiration or airway difficulties. Total laryngectomy may be performed as a primary treatment for advanced laryngeal cancer in those patients who have gross extension outside of the cartilaginous framework and into the overlying strap musculature. Total laryngectomy is performed through an "apron"-type incision that may be extended further in the superolateral direction to accommodate lateral neck dissection. Exposure of the trachea inferiorly is accomplished by dividing the strap muscles completely. The thyroid gland is divided in the midline and each lobe is lateralized off of the trachea to the point that the recurrent laryngeal nerves are divided bilaterally. In those cases where there is concern of invasion of one or both sides of the thyroid gland, the inferior thyroid artery must be identified such that the parathyroid glands may be lifted off of the posterolateral aspect of the thyroid gland and preserved. In this way, the thyroid gland is left on the laryngotracheal complex and resected en bloc as part of the total laryngectomy. Laterally, the posterior edges of the thyroid cartilage are identified as the carotid sheath contents are lateralized. This is accomplished by dividing the middle layer of the deep cervical fascia in a superior to inferior direction. Once the thyroid ala has been identified, the constrictor muscle is separated from the ala and the piriform sinus is bluntly dissected medially to enhance its preservation. Superiorly, the hyoid bone is identified and the suprahyoid musculature is lifted off of the hyoid bone for its entire length taking care to preserve the hypoglossal nerve and the lingual artery. The trachea is entered inferiorly at a site that is felt to be oncologically safe and the vallecula is entered superiorly. The pharynx isthen closed using interrupted or running suture followed by creation of a tracheostoma. A tracheoesophageal puncture may be performed primarily or at a later date in suitable candidates. It is common for tumors involving the larynx to involve also partially the neighboring pyriform sinus. In these patients, a portion of the pharynx sometimes requires resection in addition to partial or total laryngectomy.

If this is the situation hypertension with pregnancy proven moduretic 50mg, a balloon test occlusion is warranted to evaluate the potential for a stroke blood pressure medication dosage too high order moduretic once a day. The catheter is inserted via the femoral artery into the internal carotid artery and inflated. If the patient becomes hemiparetic or aphasic, the balloon is deflated and the catheter is immediately withdrawn. If the patient can tolerate balloon test occlusion for 15 to 20minutes, the surgeon may proceed with a carotid resection. However, up to 22% of patients who pass the balloon test occlusion may have delayed ischemic complications. Growth rates are variable, and symptoms may not occur until the neoplasm has obtained large size. Benign sinonasal neoplasms are discussed in Chapter 54, "Endoscopic Surgery of the Skull Base, Orbits and Benign Sinonasal Neoplasms. In those with asymptomatic benign tumors found incidentally, surgery may be recommended to establish a definitive diagnosis. In some cases, these abnormalities may be watched over time with serial imaging and/or clinical examination. Intervention may be required in those with pain, obstruction of frontoethmoid outflow and mucocele, and cranial-nerve dysfunction due to foraminal compression. Nerve-Sheath Neoplasms Peripheral nerve sheath neoplasms of the sinonasal tract are rare. Unlike other head and neck schwannomas, sinonasal schwannomas are typically not encapsulated and may have surface ulceration. More typical encapsulated schwannomas may be seen in the pterygopalatine or infratemporal fossa associated with V2 or V3, respectively. There is no high level evidence to prove optimal therapy, and most patients are treated with surgery when resectable, followed by adjuvant radiotherapy. Neck dissection is rarely indicated, although it should be considered when tumors extend into the oral cavity or when patients present with known neck metastases. A diverse group of epithelial and nonepithelial malignant neoplasms with variable biologic aggressiveness may occur and are listed in Table 108-3. Table 108-3 Malignant Anterior Skull Base Neoplasms Adenoid cystic carcinoma Basaloid carcinoma Chondrosarcoma Chordoma Esthesioneuroblastoma Fibrosarcoma Hemangiopericytoma Lymphoma Malignant fibrous histiocytoma Metastatic disease (breast cancer, renal cell cancer, etc. Squamous cell carcinoma is the most common malignant neoplasm of the paranasal sinuses. Squamous cell carcinoma of the nasal cavity may extend directly to the skull base. Stage 1 and 2 tumors may be eligible for surgical resection alone, depending on final pathology. For unresectable tumors, chemoradiation is the standard of care if the patient is medically able to tolerate treatment. The incidence of regional metastases is less than 10%, and the clinically negative neck is typically not treated. Adenocarcinomas are classified by grade based on glandular architecture and cytopathologic features. Comparison of biologic behavior is difficult due to low incidence and variable classification systems in the literature. In general, low-grade adenocarcinomas have more glandular differentiation, less nuclear pleomorphism and fewer locoregional metastases. Adenoid cystic carcinoma is the most common malignancy occurring in the minor-salivary tissue in the sinonasal mucosa adjacent to the skull base and the second most common sinonasal malignancy. Adenoid cystic carcinoma comprises approximately 10% of paranasal sinus malignancies and affects the skull base by direct extension and/or perineural spread. Adenoid cystic carcinoma usually presents as a slow growing mass with early perineural involvement. Tumor grade is determined by percentage of solid growth pattern and nuclear pleomorphism. Perineural invasion and submucosal spread are common in both low and high grades leading to a high rate of local recurrence with considerable morbidity at the skull base.

Two vertical trenches in the soft palate lateral to the uvula of variable width and length at free margin of the distal soft palate are created and the uvula reduced pulse pressure 62 order moduretic 50 mg on line. Surgery may be single stage or "titrated" to improvement in snoring or appearance of velopharyngeal dysfunction blood pressure chart with age and height buy generic moduretic 50mg line. Palatal scarring initially increases tension and reduces snoring but long-term data (five years) suggest recurrence of snoring is common. Various less expensive cutting and ablational tools have been used to shorten the palate, remove mucosa, and reduce the uvula and allow healing by secondary intension and all likely create scar and reduce snoring with variable effectiveness. Failure may be from persistent flow limitation, softening of scar, or flutter at nonpalatal airway sites. All patients following snoring surgeries should be cautioned both about the risk of recurrence of snoring and the possible later development of overt sleep apnea. To avoid the extensive thermal damage created by the laser to all three layers of the soft palate and chronic inflammation, ulceration, and loss of seromucinous glands, alternative approaches to create palatal stiffening have been developed. Techniques using ablational radiofrequency demonstrate less pain for treatment of snoring compared to laser. Maxillofacial surgery with or without combined ancillary soft tissue procedures have demonstrated successful surgical results of greater than 90% success even in obese populations. The genioglossus and geniohyoid muscles and the hyoid bone contribute to determining the position of the tongue in space. By advancing the insertion of the genioglossus muscle, geniohyoid muscle, or hyoid bone, the characteristics of the tongue can be altered. Multiple osteotomies techniques to capture the genioglossus insertion and advance the genioglossus muscle have been described including a bicortical rectangular osteotomy of the mentum, sliding genioplasties, and split sliding ramus osteotomies. Major complications or tooth damage requiring restorative surgery, however, are rare. The hyoid may be suspended anteriorly and superiorly to the mandible or anteriorly and inferiorly to the thyroid cartilage. Mandibular advancement techniques may markedly enlarge the lower pharyngeal airway. Procedures have been described as "telegnathic" in contrast to traditional orthognathic surgery. Aggressive advancement is required in sleep apnea compared to orthodontic treatment. Dentition may limit advancement in traditional techniques and orthodontic methods alone may be inadequate to maintain a normal bite. This flap allows closure of the lateral wall defect after advancement using mucosa from the dorsal aspect of the palate. Sclerotherapy agents to create scar in the mucosa of the soft palate and have been used to treat patients with primary snoring. The procedure has less pain than laser therapy: long-term results for snoring are better than 70% with few major complications. Alternatively, palatal implants have been developed and demonstrate effectiveness for the treatment of primary snoring in selected populations. Base of Tongue Soft Tissue Techniques Hypopharyngeal obstruction is surgically challenging. Ablational radiofrequency of the tongue base can be performed in the office-based setting. Complications, including tongue abscess, infection (cellulitis), tongue weakness, changes in speech and swallowing, and acute airway obstruction and edema, are rare. Both randomized blinded, controlled, and uncontrolled studies have demonstrated effectiveness in reducing the severity and improving the disease specific quality of life. Lingual Tonsillectomy Lingual-tonsillar hypertrophy may cause or contribute to sleep apnea. Historically, difficult exposure and removal in sleep apnea patients caused by structurally small underlying anatomy and concerns about airway edema, bleeding, and pain made the threshold to remove these tonsils high. Newer surgical techniques, combining endoscopes and excisional radiofrequency, allow easier removal of lingual tonsil tissue.
