INTRODUCTION

Supracricoid partial laryngectomy (SCPL), which is a horizontal partial laryngectomy procedure for laryngeal cancer, is based on preserving the respiratory, sphincter and phonation functions of the larynx. SCPL is a surgical procedure in which the thyroid cartilage and true and false vocal folds are resected while preserving at least one arytenoid cartilage. There are two types of SCPL. The first procedure in particular, is applied to glottic carcinomas where the preepiglottic space and epiglottis are spared, and reconstruction is done by suturing the cricoid cartilage to the epiglottis, hyoid bone, and tongue base: cricohyoidoepiglottopexy (CHEP). The second procedure is used for supraglottic and trans-glottic carcinomas, where the epiglottis and preepiglottic space are resected and reconstructed by suturing the cricoid cartilage to the hyoid and tongue base: cricohyoidopexy (CHP) (1).

Swallowing difficulties is the most common functional impairment following SCPLs. Several studies have reported that the overall incidence of temporary aspiration after SCPLs varies from 32% to 89%. Thereby, recurrent or occasional episodes of aspiration after SCPL can lead to fatal diseases such as pneumonia (2).

It is suggested that sparing both of the arytenoid cartilages is beneficial for the rapid recovery of the swallowing function after SCPL (3, 4). Conversely in our study, we presented a patient with constant aspiration following CHP who was treated with unilateral arytenoid resection.

CASE PRESENTATION

In this case report we present a 67-year-old male who underwent a supracrycoid partial laryngectomy (CHP) with bilateral functional neck dissection in 2015. Postoperative pathological analysis was squamous cell carcinoma with low differentiation, and the stage of the tumor was T2N0M0. The tumor originated from the petiole of the larynx and was invading the ventricules and anterior vocal cords bilaterally and extending to the anterior commissure with no cartilage invasion. The patient did not get any adjuvant therapy.

Oral feeding was attempted in the 3rd week postoperatively. The patient could not tolerate any kind of oral intake, so a close monitoring period was started. After a 3 months follow-up with a nasogastic feeding tube no improvement was observed, and so an endoscopic percutaneous gastrostomy tube was inserted. In total the patient was monitored for 1 year with the g-tube; during this period although some improvement was observed (especially with a semi-solid and solid diet), the patient still could not tolerate any kind of oral liquid intake. Although the patient consented to a total laryngectomy to prevent aspiration, before carrying out a major and irreversible surgery our senior head and neck oncologist decided to perform a one sided arytenoidectomy which was a surgical dilemma for a patient with SCPL. The logic behind this idea was purely mechanical; arytenoid cartilages which were shifted medially due to the laryngectomy were contacting more medially than normal and thus preventing the neoglottis to close appropriately. In the first week follow up after surgery, the laryngoscopic examination showed full closure of the larynx, and no penetration was observed during functional endoscopic evaluation of swallowing (FEES). In the third month follow up the patient stated that he had no complaints during oral intake and he was not dependent on the g-tube (Figure1).

DISCUSSION

The main purpose of conservative laryngeal surgery for glottic carcinoma is to provide local control by maintaining laryngeal function. In recent reports, SCPL was shown to allow excellent local control rates ranging from 94 to 98.2 % at 5 years in cases of T1-T2 glottic carcinoma with extension to the anterior commissure (5-8).

It is generally agreed that SCPL results in severe swallowing dysfunction, most notably aspiration, but eventual return to oral nutrition in most cases (9). However, episodes of aspiration can occasionally occur throughout the patient's life. Furthermore, pulmonary diseases associated with aspiration that could be life threatening and require prompt diagnosis and treatment can occur.

Maintaining proper laryngopharyngeal sensation, re-creating a functional neoglottic valve and an adequate airway and enhancing physiological coordination during deglutition are crucial for successful rehabilitation of swallowing. In addition, posterior and lateral cricoarytenoid muscle preservation with normal recurrent laryngeal nerve function during SCPL can be beneficial for neoglottic functions postoperatively. Furthermore, total resection of one arytenoid cartilage, reconstruction with CHP, and not repositioning the pyriform sinuses create a risk after SCPL (4).

Various studies have reported that sparing both arytenoid cartilages speeds recovery of swallowing after SCPL (3, 4, 6, 9). On the contrary, Bron et al. have argued that sparing of arytenoid cartilages has very little impact on the recovery of perfect swallowing. Moreover, they reported that one arytenoid resection may be necessary to recover perfect swallowing. This has been explained by the presence of a relatively wide laryngeal closure defect that causes chronic aspiration in cases where both arytenoids are preserved and most of the vocal cords need to be sacrificed. Additionally, they reported that resection of one arytenoid allows either the base of the tongue or suprahyoid epiglottis to form a tight laryngeal sphincter with the remaining arytenoid cartilage (10). Similarly, in our case, despite the preservation of both arytenoid cartilages with normal recurrent laryngeal nerve function during SCPL, chronic aspiration related to the laryngeal closure defect were observed postoperatively. This may be explained by the following situations: Firstly, most of each vocal cord had to be resected for local control. Secondly, both arytenoid cartilages were obstructing each other's medialization for neoglottic closure. As a result, unilateral arytenoid resection allowed complete medialization of the remaining arytenoid, which enables the sphincter function of the neoglottis.

CONCLUSION

Swallowing difficulties is a commonly observed complication after SCPL. Although it has been reported that preservation of both arytenoid cartilages facilitates the rehabilitation of swallowing postoperatively, we have resolved the swallowing problem by scarifying the unilateral arytenoid unit. Unilateral arytenoid resection may be considered for patients who have swallowing disorders after SCPL and where swallowing rehabilitation proves ineffective.

SUMMARY

Supracricoid partial laryngectomy is a commonly used surgical technique in which the functional properties of the larynx are preserved. Swallowing difficulties is one of the most commonly seen complications of this procedure. It is known that sparing both of the arytenoid cartilages is important for swallowing recovery. In this case report we aimed to show that sparing the arytenoid cartilages can be the cause of aspiration, and a one sided arytenoidectomy should be considered before attempting any other surgical solutions.
