ENDOSCOPIC CORDECTOMIES FUNCTIONAL RESULTS Patients treated by Type I and II cordectomies present vocal outcomes comparable to those of a control (normal) population Peretti et al, Ann Otol Rhinol Laryngol, 2003Patients affected by T1a glottic tumors without involvement of the anterior commissure present comparable vocal outcomes when treated by RT or endoscopic surgery Wedman et al, Eur Arch ORL, 2002A metanalysis of the VHI related data in the literature about patients treated by endoscopic resections or RT for T1 glottic tumors doesn t show any statistical significant difference among the two groups Cohen et al, Ann Otol Rhinol Laryngol, 2006A comparison between functional outcomes in patients treated by endoscopic partial laryngectomies for T2-T3 glottic tumors and those treated by supracricoid partial laryngectomies for similar lesions shows comparable vocal outcomes but reduced postoperative morbidity and better swallowing in the endoscopic group Peretti et al, COSM, 2007 2012
  • 23. ENDOSCOPIC CORDECTOMIES FUNCTIONAL RESULTS In a recent review Spielmann et al. examined 21 papers evaluating quality of life and functional outcomes in the management of early glottic carcinoma comparing radiotherapy and transoral laser surgery. No randomized controlled trials were identified.For vocal outcomes the majority of studies found no significant difference between RT and laser surgery.Nine studies reported QOL outcomes; seven showed no difference in overall scores. No study that assessed swallow function was identified. The evidence base to date demonstrates comparable voice and quality of life outcomes. There is a need for consensus on which measures of vocal quality and 2012 life satisfaction to be used in research trials to allow comparison between studies.

  • 31. OPEN-NECK CONSERVATIVE SURGERY FUNCTIONAL RESULTS Vertical Partial LaryngectomyThe functional outcome after standard vertical hemilaryngectomy is some degree ofpermanent hoarseness. Hirano el al. compared the vocal function after a variety ofreconstruction and noted that poor outcome was ofter associated with free mucosalgrafts.Chronic dysphagia is not associated with standard vertical partial laryngectomy, with orwithout resection of the vocal process, and 92% of patients resumed a normalpostoperative diet in one month. From Cummings, Otorhinolaryngology Head and Neck Surgery, 5th Ed. Horizontal Supraglottic LaryngectomyPrades reported a rate of permanent aspiration between 1.5% and 21%, and between0% and 50% of non decannulated patients. Prades, Eur Arch Otorhinolaryngol, 2005Sevilla et al. reported a 9% incidence of total laryngectomy due to aspirationpneumonia, and 15% of permanent tracheostomy due to laryngeal stenosis or edema. 2012 Sevilla et al, Eur Arch Otorhinolaryngol 2008
  • 32. OPEN-NECK CONSERVATIVE SURGERY FUNCTIONAL RESULTS Supracricoid Partial LaryngectomiesAspiration pneumonia is the most common complication after SCPL. In a seriesof 457 patients, normal swallowing was observed in 58.9%. Aspiration correlatedwith increased age, CHP, not repositioning of the piriform sinus, and removal ofone arytenoid. However, management of aspiration required a permanentgastrostomy in only 0.6% of patients and completion total laryngectomy in Benito et al, Head Neck, 20111.5%.Laccourreye reported tracheal tube removal in 97.2% of patients, and 52.1%achieved normal swallowing in the first postoperative month. Aspirationpneumonia developed in 21.7% and by the end of the first year the incidence ofcompletion total laryngectomy and permanent gastrostomy was 1.4%. 2012 Laccourreye et al, Laryngoscope 1998

  • 35. CONSERVATIVE SURGERY CONCLUSIONS TLS in early-intermediate glottic and supraglottic tumors allows diagnosis and treatment in the same surgical procedure, and is associated with oncological outcomes comparable to those obtained with other surgical and not-surgical therapeutic approaches. Open-neck conservative surgery offers the patients with intermediate- advanced glottic and supraglottic tumors an excellent local control of the disease counterbalanced by a long hospitalization time and recovery of swallowing function. Waiting for Level II studies comparing different conservative surgical strategies or conservative surgical treatment vs a non-surgical organ preservation protocol, selection of treatment should be customized based2012 on tumor and patient factors, with an accurate discussion on quality of life issues and specific needs of the patient.
