Oncocytic papillary cystadenoma of the larynx: a case report.

BACKGROUND: Cystadenoma of the salivary glands is a rare benign clinical condition affecting both major and minor salivary glands equally. It constitutes approximately 2% of total neoplasms and 4.2-4.7% of benign formations in minor salivary glands. Typically presenting as a slow-growing, painless neoplasm, it can be distinguished from Cystadenolymphoma (Whartin's Tumor) by the absence of lymphoid elements in histological examination. While mostly located in the oral cavity and oropharynx, it can also be found in sinonasal mucosa, and rare cases have been identified in the larynx. CASE PRESENTATION: A 75-year-old Caucasian woman presented to the ear, nose, and throat department with complaints of dysphonia and headaches persisting for several months. Dysphonia had developed months after an unspecified vocal cord surgery elsewhere. Flexible laryngoscopy identified a left-sided cystic swelling affecting the supraglottic space, leading to respiratory obstruction and dysphonia. Head and neck computed tomography confirmed a 1.9 × 1.7 cm bilobed cystic mass originating from the left Morgagni ventricle. Microlaryngoscopy with CO2 laser excision and biopsy revealed a histopathological diagnosis of oncocytic papillary cystadenoma. Post-surgery, the patient fully recovered from dysphonia, with no significant complications noted. Long-term clinical surveillance was advised to detect potential recurrences promptly. CONCLUSION: Ectopic minor salivary gland tumors, both benign and malignant, should be taken into consideration as potential differential diagnosis for any swelling arising within the upper digestive tract mucosa. Ears, nose, and throat clinical examination completed by videolaryngoscopy can easily point out the location of the mass. Imaging is mandatory for differential diagnosis and for surgical planning. Surgical excision can provide both diagnosis and definitive cure.

Sternocleidomastoid muscle flap in esophageal perforation repair after cervical spine surgery: concepts, techniques, and personal experience.

STUDY DESIGN: A retrospective report was conducted on clinical and instrumental data of 3 patients treated for esophageal perforation after anterior cervical spine surgery. OBJECTIVE: To define indications and evaluate the safety and effectiveness of surgical repair of esophageal perforations by means of sternocleidomastoid (SCM) muscle flap in the setting of anterior spinal surgery. SUMMARY OF BACKGROUND DATA: Esophageal perforation is an occasional or underreported complication in anterior cervical spine surgery. To prevent its potentially devastating and even life-threatening sequelae, prompt diagnosis and treatment are required. No treatment protocol has yet been standardized. In addition to conservative measures, several surgical approaches have been presented, ranging from primary repair to reconstruction with local, regional, or distant flaps. METHODS: Primary spinal pathology and intervention, esophageal fistulae morphology, diagnostic work-up, clinical course, and surgical techniques for their repair are illustrated in each case. Follow-up data have been gathered by in-person visits. RESULTS: Mean time from discovery of perforation to definitive surgical treatment institution was 44.3 days (range: 34 to 61 d). SCM muscle flap way used as reinforcement and protection of a primary esophageal suture in 2 cases and as a patch to the perforation in 1 case. All the fistulae healed without further complications. Mean time to oral feeding resumption was 17.6 days (range: 10 to 27 d) and mean hospitalization time was 19 days (range: 11 to 28 d). All the patients presented with a free oral diet at the last follow-up check. CONCLUSIONS: Esophageal perforation treatment has to be multidisciplinary and tailored on each individual case. SCM muscle flap, used as reinforcement of a primary suture or as a patch to the lesion, has proved to be effective as definitive treatment for persisting or recurring esophageal fistulae after anterior cervical spine surgery. In this setting, conservative treatments may be inadequate or may actually perpetuate the condition.

Reconstruction of the hypopharynx after free jejunum flap failure: is a second free jejunum transfer feasible?

Reconstruction after circumferential pharyngolaryngectomy is a challenging problem. Reconstruction methods should ensure an appropriate mucosa lining of the digestive tract, preferably already tubulized, and peristalsis. Despite the high reported success rates, the jejunum flap is still occasionally lost due to thrombosis of the pedicle and/or fistula formation. Five cases of circumferential pharyngolaryngectomy in which failure of the jejunum loop was managed with a second free or pedicle flap are presented. A second free jejunum was reliable in selected patients, depending on time of detection of flap necrosis, on bacterial control of the wound and on the vascular or general conditions. For this reason, careful monitoring of the flap and clinical signs of necrosis in the first 5 post-operative days is crucial to prevent the formation of fistulas and infection and to increase the possibility of using this kind of salvage surgery. Pedicle flaps should be used only in the event of severe complications because of their high risk of post-operative salivary fistulas.

Atypical reconstructions with free jejunum flap after circumferential pharyngolaryngectomy.

The ideal reconstruction after circumferential pharyngolaryngectomy is represented by the jejunum free flap, but when the resection extends to the oro- or nasopharynx, the discrepancy between the lumen of the flap and the pharyngeal defect represents a disadvantage. Two reconstructions to overcome this problem are presented: end-to-side anastomosis between the pharynx and the antimesenteric side of the jejunum; and a jejunal "reservoir." The type 1 technique is quicker to perform, but can result in dysphagia; the type 2 technique is more complex, but usually no dysphagia is observed. In our opinion, no ideal surgical technique exists to equal the jejunum loop. The choice must be tailored to the single patient, bearing in mind the degree of the defect, the stage of the tumor removed, the general conditions of the patient, and personal surgical experience. Whatever procedure is chosen, it should provide the best possible quality of life for the expected life span of the patient.

The use of pedicled and free flaps in laryngeal cancer recurrences: postoperative considerations and functional results.

The objective of the study was to compare the rate of complications and the functional outcomes following reconstructive surgery with pedicled and free flaps for recurrences after laryngeal cancer treatment. A retrospective analysis was conducted among the clinical records of the Department of Otolaryngology Head Neck Surgery of the University of Pavia from January 1995 to December 2004. Twenty-three patients were identified as having been reconstructed with pedicled or free flaps for hypopharyngeal recurrences after laryngeal cancer treatment. We observed a higher rate of postoperative complications after pedicled flaps (60%) than free flaps reconstructions (23%). The pedicled flaps group evidenced a longer hospitalization time (35 versus 14 days); a lower rate of patients with pedicled flaps (14% versus 69%) was able to resume a normal feeding 1 year after surgery; no patient achieved an esophageal voice, but the entire free flaps group reached an intelligible voice with the positioning of a voice prosthesis. The possibility to achieve such functional results in this kind of patient justifies the use of a surgical approach that generally requires a longer operation time than pedicled flaps, and the need for a surgical team with special skills in microsurgical techniques.
