| Article | Number of patients | Treatment offered | Swallowing outcomes | Complications |
|
| Endoscopic stapling of postlaryngectomy neopharyngeal anterior diverticulum [5] | 1 | Dilation of stricture (self-dilation with mercury bougies) | Worse | Enlarged the anterior neopharyngeal diverticulum |
| Transoral endoscopic stapling of posterior wall of pouch | Patient stated swallowing was “best it had been since before laryngectomy” | None |
| Anterior diverticulum after total laryngectomy [6] | 34 | None (this article was a study to determine which types of laryngectomy lead to diverticulum formation) | | |
|
| Postlaryngectomy dysphagia masking as velopharyngeal insufficiency: a simple solution for an anterior neopharyngeal diverticulum [7] | 1 | Serial dilations | No improvement | |
| Transoral endoscopic stapling of nasopharyngeal diverticulum | Could not reach pouch | |
| Harmonic scalpel to cleave distal portion of pouch | 2-month follow-up: no significant regurgitation | None |
|
| Management of Zenker’s diverticulum and postlaryngectomy pseudodiverticulum with the CO2 laser [8] | 11 | CO2 laser on tissue bridge | 6 patients without swallowing difficulties after first operation, 2 patients required second operation and had no difficulties after operation, 3 patients had improved swallowing but not full resolution | One patient had parastomal fistula |
|
| Conservative management of a large postlaryngectomy neopharyngeal diverticulum [3] | 1 | Manual reduction of neck swelling | At 4-month follow-up, patient presented with dysphagia which was treated the same way | |
|
| Laser treatment of symptomatic anterior pharyngeal pouches after laryngectomy [2] | 9 | CO2 laser | 8/9 noted significant improvement in swallowing (remaining patients still reported swallowing issues but had irradiation caries treated with full mouth extraction which could explain persistence of difficulties) | One patient had recurrence of neo-vallecula but reported no further issues after a second CO2 laser treatment. Another patient improved after operation but had recurrence of problems 6 months later |
|
| Influence of closure technique in total laryngectomy on the development of a pseudodiverticulum and dysphagia [9] | | None (this was a review to determine correlation between closure and dysphagia and diverticulum formation) | | |
| Swallowing after laryngectomy [1] | | None (this is a review article) | | |
|
| Management of vallecular pseudodiverticulum [10] | 2 | External approach (hypopharyngoscope could not reach inferior margin) | One patient had resolution of swallowing difficulties and the other had swallowing improvement | None reported |
|
| Disabilities resulting from healed salivary fistula [4] | 12 | None (review of cases, and in each, the diverticulum was simply diagnosed but not treated) | | |
|
| Postlaryngectomy dysphagia caused by an anterior neopharyngeal diverticulum [11] | 2 | Transoral wedge resection | Resolution of swallowing difficulties | None |
|
| Postlaryngectomy neopharyngeal diverticula [12] | 3 | CO2 laser division | One required second procedure but had improvement of swallowing difficulties | None reported |
|
| Anterior neopharyngeal diverticulum following laryngectomy [13] | 1 | Endoscopic lysing of scar tissue | Relief of dysphagia | None reported |
| 1 | External approach (transverse high cervical incision) | Complete resolution of swallowing problems |
|
| The anatomy and complications of “T” versus vertical closure of the hypopharynx after laryngectomy (Davis) | 5 | Esophageal dilation | Improvement for 4/5 | One patient needed laser excision and had improvement following procedure |
